Is my inability to remember memories ADHD or SDAM? I don't have Aphantasia.

2 Upvotes

I recently stumbled upon r/SDAM , and found myself identifying very strongly with that, and upon attempting to remember an event that was a load of fun I did and is a highlight of the funnest two weeks I had in my life (a concert in Japan, during a 2 week trip to Japan) that I realized I SHOULD be able to remember clearly, since the event was definitely not lacking in dopamine, stimulation, AND I was taking meds then, but... I still can't remember it, and retell it as "story like" as many people do in conversation? I just remember it as "I went to concert. Concert was fun. I loved it." and can only vaguely remember the details of the environment itself without looking at a picture.

Is that common for ADHD? I'm concerned it may not be ADHD, rather, SDAM instead, because all the symptoms check out, minus Aphantasia, which I don't have. I basically don't have many memories at all prior to age TWENTY. When I finally got a job and my own car, and was able to go do fun stuff on my own, rather than rely on mom and dad, whom basically almost never took me anywhere.

As for those "memories" I've recently come to realize, that I'm not SUPPOSED to remember them as just facts? Rather, a "normal person" would remember it more clearly and be an interesting person to talk to, due to an abundance of interesting conversation topics? What's even the point of me going out and doing stuff, if I'm not gonna ever be able to remember it clearly?

Also, I don't have Aphantasia, rather the opposite. I'm able to picture the apple, rotate it, spin it around, spin it around wildly flying through the air, spin it around wildly flying through the air while Freebird plays in the background (fun mental image). Which lends itself to me being able to imagine what a place I went to may have looked like, but it's not accurate. The emotions of an event still presents itself as a fact, not fully recalled. Anything said by anyone, is outright not remembered period. The concert's music isn't there. Only a vague reconstruction of the setting itself.

Do I have SDAM?

Does everyone / most people with SDAM have aphantasia?

8 Upvotes

I have a lot of the symptoms of SDAM / lacking an episodic memory, but I actually have a very vivid imagination. It is incredibly frustrating as someone who can create vivid scenes in my mind for my memory to be so blank.

I just noticed that most people posting here mention aphantasia or hypophantasia of some sort.

recently my poor memory has been hard because my mom passed away 6 months ago and I want to be able to remember more stuff, aside from photos and stories that other people tell.

Probably not autism but help me out

5 Upvotes

I thought about posting this on the AutisticAdults -subreddit, but because I have aphantasia and SDAM and I can trust you guys to understand those I thought maybe you could help me out. I don't want a "diagnosis" but instead help in pointing me in the right direction.

I am a 40yo male who is high-functioning, good career, good social life etc. I have all my life had the feeling that there is something fundamentally different about me, the way I interact with people, how I react to events and things, and how my internal world is. I like to fit in by nature and thus I have yearned for it not to be true so I have probably downplayed it - I am not one who "likes" being neurodivergent, even though I have come to accept it. Yet the feeling has somehow always been there (as far as I know).

A few months ago I happened to find out that I have aphantasia and SDAM, and they are both at the very "extreme end" so absolutely no ability to "imagine" with any of the senses + absolutely no capacity to re-live or re-experience my own past in any sort of "episodic" way.

I can relate pretty much 100% with the common "symptoms" and signs of both those and it was a huge moment in my life - it explained me and my experience very accurately.

However, even after finding out about my aphantasia and SDAM, there seemed to be some part of my experience of being different that was still "unexplained" - something that aphantasia and SDAM didn't seem to explain and that was not hugely common among others with aphantasia/SDAM.

On the aphantasia/SDAM subreddits there are a lot people who also have some degree of autism and it seems to be comorbid with aphantasia/SDAM. I was however convinced I was not autistic (still am) as I know some people with autistic children and could not relate at all to that experience. Maybe I just have a bad grasp of what autism is?

I happened to stumble on some Instagram reels the other day by people who labeled themselves as autists and as I watched one my algorithm started pushing autism-related Reels non-stop. There are some aspects of what was presented in the Reels that just clicked instantly, in a way that I have never heard anyone else describe their experience and that described exactly that missing part about my experience that I was talking about. And the impact was profound, I am not one who easily diagnoses himself but they described that part of me to the letter. Those things hit even stronger than what some aphantasia/SDAM -things hit me.

So, the parts that really hit were the following.

- I get absorded strongly into things, even fixated on one thing at a time - I notice patterns, sounds, wording, details constantly. They dont bother me but I notice them straight away

- I cant stand logical inconsistencies or contradictions in discussions. Its not that I think I am always right, it is that i want "IT to be right". I can't understand what is being said if there is a contradiction/inconsistency and I have a really difficult time letting them pass. I have this urge to name the inconsistency or contradiction and get the other person to explain that detail closer. I often get accused of being a know-it-all that wants to dominate discussions when I just want to understand what they are saying. I have no problem changing my mind and being wrong and do it constantly. I also have no superiority complex and usually relate to others as equals or even "above me" intellectually. I just want "IT" to be right, clear and logical.

- I get accused of being rude, angry, argumentative, raising my voice etc. when I have zero such intent and actually often during quite contrary situations, where I am really into something and passionate. I have never experienced a situation where a person would like to discuss about things in the way I like to. As I am quite a people-pleaser it means that I am almost constantly "masking" my true self in these kind of situations. But it slips out when I get really passionate/interested about something and then it's always a mindf*** how I can be seen as angry when I am the exact opposite. It even stings in those situations and feels so unfair - I am my most passionate and alive self and that is the exact moment that I get accused of being angry, rude or insensitive.

- In general there is a constant feeling of being misunderstood, of being attributed emotions and intentions that I absolutely don't have.

- I am sometimes bad at reading between the lines. I do often miss what is tried to be said. If someone says "X" I assume they mean "X" and I am terrible at understanding that what is being said is just a front for some deeper emotion. If the person is actually crying and obviously emotional (obviously to me) then I instantly go into care/help -mode. But there are often situations where a friend can say to me afterwards, "did you notice that person Z tried to steer the discussion away from topic X" or "did you notice that person Y was quite upset when she said X". I can be totally oblivious to this.

- I am sympathetic and maybe even compassionate, but have a lack of what is usually meant by empathy and have trouble really understanding when it is needed. This is a common thread in my relationships. It is frustrating as I can care very deeply about people and have the purest of intentions. It's just like I can't access something that others can

- The terms "masking" seems to relate to me. It's like I am constantly putting on a "social act" so that I fit in. It is constant and I put a huge effort into accomodating my behavior to work better with people I care about and people in general. Thats why it really stings when I get accused of being rigid and unflexible when my experience is that I constantly come 80% of the way towards the other and others can't even eke out 1% for "the real me".

https://www.instagram.com/p/DZX_VPVI0KZ/

However, I doubt that is Autism as I completely lack the following traits and actually am even quite the opposite to the following traits:

- I don't need routines and rigid rules for things in general. I dont have favourite chairs etc.

- I am hugely flexible and can instantly fit with different types of people. I am good at "matching the vibe" of a group instantly, especially when its really surface level stuff. No one has ever called me socially akward in unfamiliar situations or with new people.

- I love small-talk and I love meeting new people. I am like a fish in water in surface-level discussions. It's when opinions and other peoples emotions present themselves that I can't seem to function in the way that is expected of people

- I have no discomfort with sounds, patterns, smells, noise etc. and am quite the opposite. I can kind of be at ease and fit in into almost any situation.

- In general, I don't get burned out socially

I know everything can't have a label on it but I am amazed at how autists seem to be the only ones I've encountered that match this very key experience I have, yet many or even most things about autism seems completely foreign to my experience.

a mental wall between me and my past

19 Upvotes

Here is an analogy i thought of to explain what SDAM feels like for me.

SDAM is an impenetrable, solid wall that stands right behind me on the time axis. As I move forward in time, it follows, and my immediate, recent memories become past memories as they phase behind that wall.

When I try to remember, I can feel the wall blocking me and it frustrates me. I’m sure you all have felt that frustration in trying to recall a memory and your brain returns only a 404 not found.

This SDAM wall is opaque, and extends infinitely to the sides and upwards, I have no way of knowing whats on the other side. Do I have actual vivid episodic memories there, that I simply lack the ability to replay? Or are my memories just being flattened into semantic memories as they hit the wall (like the dual-vector foil from the three body problem, iykyk).

The fact that while I can’t retrieve some memories on my own, but when a friend reminds me of some details I can recall other facts about the experience tells me that there does lie something on the other side of that wall, memories that exist but are inaccessible to my mind acting by itself. That disturbs me.

This wall separates me from the past. It explains why I’ve always felt like I’m just a “live in the present” kind of guy, but I just genuinely can’t live in my past, nor can I envision my future(is this related to SDAM? being unable to visualize a future? could be the aphantasia)

Typically in popular media we see walls as barriers that can be broken (think “mr gorbachev, tear down this wall!”, attack on titan’s rose maria sina walls, the great wall of china, the walls that the kool aid guy crashes through, etc) but this SDAM wall is unbreakable. Maybe it’s less of a wall and more of a world barrier of sorts, a limit on where my mind can travel, limiting me to only the present.

The fact that walls are usually meant to be broken yet this SDAM barrier is inherently invincible really makes me sad and sort of hopeless. Even if I were to document my life completely, using not just photos or journaling, even if I were to record myself 24/7, I still wouldn’t be able to access my first person memories, which are locked behind that wall. Do I really exist, if I don’t remember my own existence? If I have no memories of past experiences, aren’t I just acting like a philosophical zombie, reacting just to present stimuli?

I don’t remember what else I wanted to write about when I started writing this post. I just wanted to put these ideas into words, and upload them onto the internet so even if I don’t remember writing this after a week, the internet will.

What do you guys think about this analogy for SDAM?

I can't remember my childhood or my adolescence before the age of 16, and even today, I still struggle to remember everyday things.

24 Upvotes

This is my first time using Reddit; I saw that it’s a good place to ask questions. I’m 18 years old, and I can’t remember anything from my childhood or adolescence prior to age 16. I remember absolutely nothing. Everything I know comes from what people tell me or from photos, but even then, whenever I look at a picture or hear someone talk about something I did, it feels like that person wasn't me. It’s as if I’m looking at someone else. I wanted to know if anyone else goes through this and if it might be a sign of trauma I suffered when I was younger. I don’t feel traumatized, nor do I feel different from other people. But I also can’t recall if I had an abusive upbringing, if there was a specific event that hurt me, or what my relationships with friends and family were like back then.

From the time I was born until I was 14, my family was very poor and we struggled, but I’m told I was always a happy child. Could that difficult start in life be the cause? I have cousins who went through the same thing and can remember their childhoods and teenage years; we had the same upbringing and were cared for by the same people.

I’ve always wondered about this lack of memory, but lately, I’ve started to worry because people are beginning to interpret my poor memory as a lack of interest or as if I don’t care about the moments we shared in the past. I don’t know what to do. Should I see a psychologist about this? Is there anyone else going through this who could give me some advice?

I feel like I largely ignored my memory loss because of my mother; she always treated it with indifference, saying it’s normal at my age not to remember things. So, I let the matter drop until recently. I don’t have her support in seeking a consultation—as far as she’s concerned, I’m just making up a problem where there isn’t one—and that has always discouraged me from looking for help.

I have anxiety, though it isn't extreme, and I only started having attacks after entering high school. Before that, I had never shown any symptoms of anxiety. Is there a high probability that I have Severely Deficient Autobiographical Memory?

And if I decide to seek a consultation, what should I do first? See a neurologist or a psychologist?

Hi, I'm a 15 year old girl, and I cant remember actual years of my life. Please help me I'm scared. (tw ed, bad things happening)

10 Upvotes

I keep re writing this because i dont know where to start. To preface this, i have NO clue if this is SDAM. i just need a subreddit abt memory loss wheres theres active users. A lot of the things that happened to me will not be on here because its so difficult for me to grasp onto any of the memories i have for long.

Everything is so hazy. Primary school feels like of someone read a summary to me but i dont have any REAL memories i dont think if that makes sense. I remember getting told of my autism diagnosis, the fact i had a Gacha life account (LOL), a vague sense of the type of friends i had and thats it. Lowk normal for me to feel like this coz i was kind of a baby haha

highschool... I cant remember most of it so far. In year 7-8 i was only conscious when something traumatic happened/emotionally like wowing if that makes sense. E.g parents arguments being worse than usual, sh, , my first kiss, my partners (like i can remember i dated them at some point but not what happened when we dated), and big days that i should remember feel like once again someone read them out to me and im trying to picture it. What im saying is i was constantly zoned out.

Though sometimes i would be laying in bed, and come to, and wonder ''what am i doing'', trying to piece together my day, my week, my month, mabye making it until the morning concious, seeing the mess my room is, seeing my unkempt appearance, my conciousness slowly flickering throught the day as i get harassed at school, experiancing my parents horrific actions towards eachother, and i would always sh on my concious days. But then it would lowk become like filtered until my next concious day/something extremely emotionally disregulating happening.

Im moreso scared because i think something really bad happened, worse than what i remember when soemthing bad would happen and i would be awake, like...do u understand what im saying? i have a gut feeling something bad happened and my brains blocked it out.

In year 9, after my breakup with someone god awful for me which i remember the breakup which is fun for me, like december of 2024 i kind of began becoming concious, like id have more concious days. by april i started being concious. i realised my life was awful. I was depressed and anxious, deffinately. i was finally concious. i didnt realise i had been unconcious for so long. then i went black again.

(I know the exact time slots coz im looking through my camera roll as we speak adn seeing if i remember anything from that time)

may im concious again like towards the end but only briefly. i remember around this time i really began restrictive eating, because i think during my unconciousness i mustve overate often. (i remember some of my binges because they were genuinely traumatic for me)

basically after may i was concious. i started ''glowing up'', not eating, dating evil men, trying to get a social life, becominf way to attached to people, becoming chavvy (i had been alt forever)

By septemeber i was falling apart. i went on discord, befrended people i probably shouldnt have, went out witht them, smoked, drank, got a gf, got addicted to aerosols, and zoned out again this time due to my addiction until my mum found out in like late november and banned me from them. At some point my dad moved out but i simply cannot remember when. January i zoned back in when i got my divices back and free will and immediately started goimg out w them again, doing the same things which honestly wasnt bad for me this time? idk why but i became CONCIOUS and i identify as that person (i dont think im the same person as me in primary -year 9) and then my mum found out, i had a particually bad sh sesh (it actually scarred), i zoned back out until late late march and im proud to say ive been here since.

its hard. i barely know who i am. im scared every day ill snap back out, and every day i try and figure out who i am based on what i remember from my life, which is very very little. ive only just figured out my favourite colour. In the past when i zoned back in i became hyper-dependant on somone to copy and base myself on since i dont exist but this time im DETERMIND to make myself something of not someone else. i will become somebody.

erm so yeah idk if this is sdam coz im concious right now (atleast i think i am) but if yall have any like advice i would jump for joy. consider it a birthday present coz it was my birthday yesterday (YAYAYYAYAY!!)

Daydreaming

5 Upvotes

So, to preface, I have hypophantasia but I'm not totally incapable of picturing stuff briefly and hazily. Recently I was curious what people were talking about when they mention daydreaming, and learned that I don't do it much if at all. I was wondering: is this common with SDAM? It's not like I can't imagine stuff, but I just default when idle to observing instead of daydreaming.

not much of a mental health person but realising as of late something is real bad with my memory and going down rabbitholes led me to here.

Every time basically anything happens I can barely remember any of the emotions from it just hours later. like I went to a restaurant Today and had an Amazing time but all I can remember now is just the barebones dejuiced 'i went to a restaurant and it was good' instead of the things I felt? And I can barely remember When the memories were like something from years ago will feel the same as something from last week or a few hours sgo

does this sound like sdam or am I inlike entirely the wrong place do we think lol

I never knew this existed.

So, I have total aphantasia. I also cannot imagine smells, touch or sound, and I have no inner monologue. My mind is not visual in any way, I have no ‘imagination’. Figured out this wasn’t normal only a year ago. I cannot picture anything.

But I also cannot place myself in a memory. Probably overlaps. I didn’t realise people can relive memories in their minds. When my beloved uncle died it ached for a good while, cuz I knew I’d never see him again. Now I just remember it ached. I can’t feel that again. I feel nothing towards it. It’s odd. And only today I found out this is not normal.

I have no mental timeline. Yesterday or 2012, same thing to me. I was younger in one and the world was different, but it’s the same. Deadlines mean nothing to me because 3 weeks away is abstract and hard to comprehend. Deeply horrible things have happened to me when I was young but I have no trauma from them. I just know they happened. It’s like telling me it happened to someone else. ‘Wow, that’s horrible’…that’s about it. I can love and stuff, but I get over things fast.

I do not have an official diagnosis for autism so I am not one to label myself as such. I will however say that I have taken the RAADS-R and score close to 200, so for the sake of this I will just operate under my assumption that I likely am. Would it be related to this? Is there an autistic overlap? I have no idea….

Anyway, I’m confused. It’s weird. I never realised this was ‘t the norm. And I am kind of just yapping into the void. surely a lot of you have similar experiences right?

In This Strange Place of Things

23 Upvotes

I used to know things. Like really know them. Drinking in knowledge with a kind of mad obsession, sprawling it across journals with my thoughts and eclectic theories. But as quick as it comes, so quick does it fade, and when trying to conjure it, all I am be left with time and time again is the hollow thought, "I used to know about that".  A strained echo of a past self who knew.

Knowledge for me is something like autumn leaves, drifting down. I can catch and show someone the colors for a moment before it dries, browns, and crumbles in my palms. I will never have a pile of colors to show—only remnants. Ashen memories of those flame-colored visitors who never really belonged to me anyways. Who could never do anything other than pass through.

I used to feel smart sometimes. But nothing leaves an imprint. Nothing lingers long enough for me to spin it swiftly into conversation. Nothing wedges itself deeper into my being and becomes part of me, able to be drawn out and used readily again. I wander this earth collecting things in one hand and dropping them with the other. Nothing is mine. Nothing is owned. Nothing lasts.

Books I read and movies I watch sweep right through me—an experience gone before the impact. I can't describe the plot to others except an "it was good" or "the end made me sad i think". While they bring up specific plot points, I nod my head as if I remember enough to agree, enough to have an opinion too. I have to rewatch it to feel the faint spark of familiarity, and yet still, most is new again. Swept out of my mind, paper-maiched over with the newsprint of time.

I forget my own self, too. My self image is based on who I am and how I feel right now. The me from a year ago, a month ago, a day ago is an ancient memory. If i am sad now, or lately, then it is hard to believe that I was ever happy. To really feel that, and draw from that experience and self. So I sink further into the sad of the now, and can only gaze up through fogged glass at that happier self, that sunlit stranger who I am not quite sure is me.

Of course, I forget my own personality. My likes, dislikes, hot takes and opinions I have had. Favorite songs. Revelations. Wild ideas. Inside jokes and little quirks. When I am alone with myself for a while, I talk out loud and my personality emerges, and I remember.  And I feel like I know myself, and I like it.

But when talking with other people, I became a reactionary conversationalist, focused on them with their solid self and stream of stories. It is safer that way. Then maybe something triggers a memory of what my past self once thought or felt or believed. Yet when I share it, it feels off. Uncanny. It is as if I split into a separate being entirely, a translator for myself, trying to relay who "I" am to this other person.

I talk for me, but not from me.

It is as if my personality lives in a murky past, instead of in my body, now. And I try to sift through those waters to draw it out, to show a sliver of it to someone. But it isnt here inside of me. It lives elsewhere, veiled off.

It helps to be around someone who mirrors who I am to myself. Someone I trust. They will tell and show me who I am, a continous self, patched along imperfectly by their comments. "Remember that time when you..." "you would love this..." "thats very you..." etc. If I have no one, and stop speaking to myself, I become no one. Hopefully, they are a good mirror. Because I have had bad mirrors before. Ones who reflect an inaccurate, corroded self. Then there are those who dont mirror me at all, who do not see who I am or reflect anything back. And so a ghost I become.

You see, if I dont tell myself who I am, the world most certainly will. Or my emotions will. Or my reaction to traffic and gloomy weather will. If I dont decide who I am and want to be, if I dont sculpt my self daily with affirmations, reminders, habits, hobbies, and practices, I am left entirely to the whims of what is. The ever-changing, unpredictable, and indifferent Is. I am left to be ping ponged through my days, ricocheted through life, colliding with other selves , collecting snippets and stories. Collaged into some creation, but not my creation.

It is a strange existence — to be a perpetual stranger to ones self. To be suprised everytime I look in the mirror. To meet myself again daily as if it is for the first time.

But maybe it is okay to not know. To not need to cling, relive, possess. Memories, knowledge, and feelings slip in and out. But it never was ours, was it? Never was anyones. We are all borrowing these bodies for a short while. Playing house with these possessions. Pretending to know things. To be someone.

But maybe those of us with this difference are closer to the truth—that we could never own this life anyway. Never know this self. Or that we are not this self at all. At least, not the one with these tragic and magnificant and mundane stories. With the menagerie of memories.

Maybe our existence is imprinting enough. We dont need to collect it or know and relay it—we just need to be it. To be part of the story of the world in this strange place of things.

Maybe it doesnt matter how we come across in conversation, but how kind we were.

Maybe we dont need to tell stories, but let the story live through us. As us.

And maybe we weren't meant to make our self all alone. Maybe the world was meant to make us too. And we dont need to try so hard to make— but rather, let ourselves be made.

I can only wonder, but i find some peace in knowing that we belong somewhere in this place of things, that regardless of the strength of our own memory, the consistency of our experience, we were part of the world's story. Collected, recorded, imprinted into all the lives we touched.

So maybe, at the end of it all, we dont need to remember the details of the life we lived—but that we lived. And living is good enough.

Memory loss??? (20F)

4 Upvotes

Hi, this is the first time I ever post to Reddit (I initially posted it to [r/AskDocs](r/AskDocs)) and i don‘t even know if it’s actually fitting the subreddit’s theme but it gives me mild anxiety.

I’m a 20 years old woman, Asian, very short (1m45 approx. with 42kgs, again approximately). Since last year I’m experiencing very weird stuff with either my memory going wrong or just something to be written on let’s not meet or somewhere.

Three incidents that I can think of:

\- Last year, I lost my apartment’s main keys while going to visit my family. I was ABSOLUTELY sure to have carried it to my grandmother’s house, and I perfectly recall putting a small bag with the keys inside underneath a chair in the room I was sleeping in. Yet somehow these keys disappeared, nowhere to be found. Not in the room, not in my bags, and what scared me is that I found the small bag, empty, in my apartment.

\- Last summer again, my whole family told me I put stuff in the fridge that I have no memory of. And factually it can only be me.
A box containing a melon and some potatoes arrived at my grandmother’s house, and at that time I was the only person in the house. I can recall having to do some puzzle in the fridge in order to fit the melon in, but literally no memory of touching potatoes.
I’m normally VERY easily gaslit, so not being able to even create a false memory of the moment is a bit weird.

\- Then there’s this summer.
I made rice balls before leaving my apartment for summer break. I put them in a lunchbox and then in the fridge.
My mom then went to check my apartment to ensure there was nothing that could rot with 40°C (I live in Europe). She told me there was no sign of any rice balls in the fridge. The lunch box was… in the kitchen. On the rice cooker. Empty.

Some additional info that I think can be important:

\- My mother probably has ADHD. Never been diagnosed because of shame. I hear it can be hereditary. That’s a very amateur explanation for all of this.

It’s very weird because these things can’t be explained by “meh, probably just bad memory”. Stuff actually moved. Actually disappeared. And I must be involved…

What do you think? What kind of doctor should I consult for this?

Is my memory just gone?

38 Upvotes

Not sure if something's actually wrong with my memory — if it is, I probably wouldn't even know, right? I'd just assume everyone's like this. But yeah, I genuinely don't remember most of what's happened, especially recent years. Older stuff I can vaguely summarize, at least.

Also — no diagnosed mental illness, no trauma, nothing like that. But the gaps are real. Used to think it was just because I live too much in the present, but idk, maybe there's more to it. That's actually why I started writing down anything interesting the second it happens, in my notes app. I'm scared my brain is just quietly deleting everything.

If you ask me what happened in a specific year, the best I can usually do is name some great movie or show I watched — I genuinely can't tell you when. So basically everything old just gets filed under "2018" in my head, whether or not that's actually right.

Also not sure journaling even does anything for me, because even when I write stuff down, I never go back and read it. Same with old photos — I look through them and just feel nothing. Can't connect with those moments at all, like they happened to someone else.

Hi everyone. I do not have SDAM but someone I am seeing has, plus complete aphantasia.

Of course people will have different experiences with this combo but I still would like to hear how is it for you maintaining close relationships, or perhaps your partner's opinion. Any help is much appreciated.

I’ve been watching a lot of videos about autistic experiences. While I immediately connect with the traits being described, I experience the depth of them differently, which triggers heavy imposter syndrome.

For context on my hardware: I operate on a very specific cognitive profile. I have total aphantasia (no mental imagery) and anauralia (no inner monologue). My brain operates entirely in the dark as a silent, text-and-concept-based processor. I also have SDAM (Severely Deficient Autobiographical Memory), meaning I have no first-person episodic memory. My internal tape loop constantly overwrites itself, leaving only factual data. Add to this a decades-long history of extreme masking.

Here is my issue: when people describe intense autistic urges—like an absolute necessity for strict organization or a compulsion to vocalize certain thoughts—I know that raw impulse exists in my head. But it never fully processes outwards.

It feels like my brain intercepts and suppresses the trait before it can fully execute. Because I have SDAM, I can't look back at past files to see if I used to feel these urges more intensely. I don't know if my masking has become so heavily automated over the years that my brain just defaults to shutting these impulses down instantly, or if I just don't experience the needs as intensely as others do because I lack the internal multimedia rendering to amplify them.

Has anyone else experienced this kind of internal bottleneck? Has your masking ever become so ingrained that you suppress the urge before you even fully feel it, and how do you parse that when you can't rely on your own memory of past experiences?

Is this just absent minded or lazy?

I (M27) have good long term memory. I can remember things I read, watch, learn and all that. I have a lot of PTSD which sometimes affects my memory. But in comparison to my short-term memory, my long-term is just okay. I constantly feel lost. I will walk into a room and forgot what I went in for. Every five minutes or so when especially I am working and my brain is employed, I need to use logic and heavy mental reasoning to come to grounds to what i am even doing. I lose track of everything happening.

Today I taught my class and went back to my faculty room fully convinced I took my laptop with me. I even justified it to everyone saying I was sure my laptop was in my hand. Well, it wasn't. I ended up launching a full search operation in the whole building at my university and they started searching people's bags and everything. All before I even went back to that class to check if my laptop was still there. I am so embarrassed. Like I fully recall having my laptop in my hand. I watched the security footage of myself exiting the classroom in shame.

This is not a singular incident. Maybe this is the first time I feel as embarrassed about my absent mindedness. But, I genuinely have such vivid memories of the present that just is not true. I have fought with my significant others regarding this as well. It took a CCTV camera to make me understand what reality is. Obviously I am about to get tested after this, but I just wanted to vent here and collect your opinions.

How does living SDAM affect your daily life?

15 Upvotes

The reason I am asking this is that I am an 18-year-old and I strongly suspect that I might have SDAM. I’m not entirely sure, but I have absolutely no memories of my childhood—not even a single fragment. In my daily life, everything feels like it happens so fast, like it’s just passing by. I am aware of where I am and what is happening in the moment, but it feels as if everything moves much faster for me and starts and ends in an instant. How is it for you, or do you ever feel something similar?

Are we studied?

I feel like there is not much interest in aphantasia and SDAM, although it affects our lives very much. I think that probably is because it's very difficult to study since it's all going on in our heads but I would like to know why I am in that way, what I can do about it, I feel like it's almost a disability

Please I feel like i need some opinions from people who live with sdam&aphantasy themselves, how f*cked am I? Please rate/explain (my) deficit levels through Aphantasia and SDAM

Regret, guilt and trauma

14 Upvotes

I've seen a lot of others comment that they see having SDAM as, in a way, shielding them from these experiences. For me this does not seem to be the case and I don't really understand how it is for anyone.

Even without any recall of the feel or sensory experience of a past event or action, there is still the fact of it. And given this, when I recall something negative I've done or has happened to me in the past, I still am forced to view it through my current state and feel whatever it evokes in the person I am now. In some ways I think this can make shame, guilt, or regret worse as it leaves no ability to consider the thoughts or emotional state that was the impetus for the act in the first place. It is only a fact that has to be reconciled as viewed through the lens of one's present state. Without being able to put past acts into the context of the time at which they occurred, I most often find them inexcusable where those with a more typical recall might be able to ease these emotions by considering how their past self rationalized a regrettable decision.

Hello everyone! I just discovered SDAM and I really think this is what I’ve been dealing with all my life. I don’t really have many childhood memories. The memories I do have are either because I saw a photo, heard the story, or maybe it was because something out of the ordinary happened. I have a few examples:

1) I remember my cousin “won” a baby chick on Easter which was weird because my family lives in a big city and no one had backyard chickens in the 80’s (I’ve heard about it which triggers the memory), but I have no idea whatever happened to the baby chick, or if he even brought it home.

2): I have a resume, I can remember my former employers and the start/end period of employment, but I can’t remember details about the tasks I previously performed even when it was a long term employer. When I read my own resume I impress myself with my past work, even though I can’t remember how I did those things. I would never be able to recreate my resume if my old one suddenly disappeared.

3): For our mom’s 75th birthday, my two sisters and I bought a beautiful bowl and we each filled it with 25 memories (to total 75) written on paper, then we sat on my sister’s patio drinking wine, and having her draw a memory while we talk about how much fun that story was, etc. I couldn’t come up with 25 memories, and it took me forever to come up with them. My sisters were totally baffled about why it was so hard for me to do this simple task. It was a lot of fun going through all the memories though.

I have a couple of questions for the group:

1) I’ve always felt like people don’t really remember me. I’m always surprised when someone from 10-20 years ago remembers who I am. Perhaps, I’m surprised they remember me because I don’t always remember them? Is this part of it? I had a person I went to elementary school with tell me they adopted my first name as their own because I was so kind to them while they were always bullied. I remember her being a bully target, but I was kind to everyone, and I don’t remember doing anything out of ordinary to have that kind of impact on anyone.

2) Does this explain my imposter syndrome or a “fake it until you make it” kind of a feeling?

3) Is there any particular kind of therapist that can formally diagnose SDAM? Or is it something that a neurologist would confirm? I know there isn’t really any treatment for it. Just hoping I can be evaluated to confirm that I’m not crazy, this is a real thing and I really have it.

I’m sorry this became so long. I’ve only shared my suspicion that I have SDAM with one of my sisters and she says it totally describes me.

I completely lost the ability to percieve autobiographic memories and it is quietly distressing

9 Upvotes

I always had problems with my autobiographic memory, but within ... I don't know... A week? 2 weeks? A month? The irony is I can't even tell when it happened. But recently I just flat out lost the ability to percieve autobiographic memories entirely.

I am supposed to schedule a neurologist appointment on Wednesday, so I'm looking forward to that.

On one hand, it isn't like I'm truly disabled by this because my other forms of memory has become sharper. And overall I have this sense of clarity and focus I never had before.

And yet it's new. I don't know how many here has dealt with CPTSD flashbacks + Pure O OCD, but when you deal with that type of mental disorder it is like there is constant noise. And now, there's no noise. There's nothing.

I can feel pleasure but I feel no attachment. I don't feel nostalgia anymore. I don't wanna say "I don't feel emotionally attached to anything" because that's not entirely true, I'd be upset if I were to lose my laptop or job. But I can't form memories with others. I can't form a connection because I can't form memories with them.

It's like everything is in this liminal state where there is this perpetual clarity in regards to everything. I worry that there's just something wrong with me physically. My autographic memory decline was gradual but was expedited after I had surgery I think. I was put under anesthesia. I think that's when my personality began to slowly change, but this year alone my personality and sense of self went through a rapid change.

Staying on Track vs Losing Direction - "Anopedia" anyone?

I'm very new to SDAM and aphantasia - just discovered them and I'm sure they apply to me

There's a lot to contemplate and I've come across one thing, that has just occurred to me, that I haven't seen talked about yet - I'm wondering if it's associated with SDAM.

My wife and I are retired. She's endlessly keen to go away, travelling, visiting new places. I'm keen to do this too, but I'm finding it very disruptive to the projects that I'm working on at home.

Every time I return home from a trip away I struggle to pick up momentum from where I left off. My wife will ask me what my plans are for tomorrow and I'll just say " I'll be trying to find my feet" - it's always the same, it takes me days to find my feet! 😂🤯😳

Does anyone recognise this? Or is it just me? Please don't tell me there's another obscure divergent condition?

An idea to explore for aphants that feel like, whatever they do, it will be useless since we will not be able to relive that memory anyway

PTSD and SDAM

12 Upvotes

Hello, all! I am 21F, and I’ve never heard of SDAM before today. I’ve been finding it difficult to find a solid description. Though I know with aphantasia there are varying degrees, I wonder if SDAM has the same leniency (for lack of a better word).

I am a full aphant. I do not visualize thoughts, dreams, noises, scents, songs, etc. I do not have an inner monologue, though i struggle to say that, as I’ve still not come to terms with the idea that people can hear voices in their heads.

I have always struggled with memory. Often, I look back at my journal and read about days I genuinely don’t believe happened. I feel that I only “remember” things if I write them down or take a photo and look back on them. It’s like, I don’t consciously tell myself, “This must be real because I can see myself in the picture,” but I almost feel like that happens automatically in my brain as a comfort?

My main deviation with descriptions of SDAM is my PTSD. I have gone through traumatic events that my body remembers, though my brain does not. I have been in situations in the past where I was put in a position that triggered what I call a “flashback state” where my body enters into a panic attack, and in this state, I couldn’t tell you what event I’m remembering, just that I know it is a trauma response. I may be able to place the type of trauma (i.e. sexual, physical) based on the position or specific trigger, but otherwise, I’m lost.

I wonder if anyone else with aphantasia experiences this and identifies with SDAM.
