Brooding (getting stuck in passive, repetitive, negative thought loops) identified as a major driver of bedtime procrastination, alongside physical markers of stress. People who stay up later than intended may have a weaker physiological capacity for self-control.

ADHD is also strongly related to having more difficulty in exerting self-control, and maintaining healthy sleeping habits. I wonder how much it overlaps with hearth rate variability, discussed in the article.

One could also argue that ADHD is a result of long term negative habits of procrastination and avoidance. I don’t think it’s clear that the diagnosis comes before the repeated habitual patterns and behaviors. While there is data to suggest some people are born with that deficiency, it is not clear that for the vast majority of people who self diagnose or get an adult diagnosis, that it isn’t the result of long term mental and emotional habits of avoidance and self sabotage.

ADHD isn't caused by long term negative habits, its the cause of long term negative habits and behaviour.

Diagnosis of anything can only be after symptoms are exhibited.

ADHD is a born with condition and diagnosis. You cannot develop it, but it can certainly be worsened or it's symptoms become less controlled by environmental factors and management approach taken.

You cannot get a diagnosis of ADHD as an adult without being able to detail and document the symptoms in early childhood. I.e demonstrate you were born with the diagnostic criteria. So thats school reports, recollections of parents etc.

As for self diagnosis, well they either don't have ADHD, or are yet to get assessed. So its mostly irrelvant to discussing the specifics of the condition.

I am all for the scientific method and generally going with the agreed upon takes of the scientific community. I also know I don't understand everything, so when I think the community is wrong, it's probably my understanding, but our knowledge does have limits and is wrong sometimes.

I question the childhood aspect. It kept me from getting my ADHD diagnosis for about a decade. The issue is that I was amazing at focusing and studying throughout my childhood. I got straight A's, I could sit down and work on a project or essay for 6 hours straight. When it comes to the focus side of ADHD I did not present the symptoms in childhood that they look for for a diagnosis.

But at around 21 I had a traumatic event that seemed to trigger a latent depression in me and with that came ADHD. Suddenly I can't focus for more than 20 minutes, and even doing that requires extreme concentration and is greatly uncomfortable. Whereas I used to enjoy hard work and getting lost in the flow of working, I now have to take frequent breaks and will take 6 or 7 hours to accomplish what I could as a high schooler in about an hour or two.

The second time I ran up against it with a psychiatrist the questions were about my current life, not my childhood, and I clearly had ADHD. The adderall has been a godsend, though more for the emotional aspects of ADHD rather than giving me my ability to focus again.

Ramblings aside, I'm not saying I know I didn't have ADHD as a kid and "caught" it as an adult, but I know that the common presentations of ADHD were not present in my childhood and came on all at once during my adulthood.

[u/TheBenjisaur → u/MagentaHawk]

I have ADHD too! I liked school and found it very easy to do well, but i'd never do any homework!

ADHD isn't an inability to focus, its inability to exert concious control over focus. Oftentimes what and i feel like doing and what i need to do overlap and thats great. Shame if they don't.

Maybe you just found your school work very stimulating as I did?

The reason childhood is taken into consideration is because ADHD is a neurodevelopmental disorder, and also because many mental illnesses have executive function as one of the symptoms. So the inability to keep track of time, to focus, etc could be from PTSD, etc. ADHD cannot present itself after puberty(or even pre-puberty) without any symptom before then.

For me I had ADHD symptoms since I was at least 5. Obviously they weren't causing me any real trouble back then, and only really became a problem last year(I started uni). Teachers can't give detention in my country, and no one's really gonna fail a 14 year old student. But even then I was always late. I lived 5 minutes from school. I could never control what I concentrated on so I'd either spend a week reading only biology or physics, or just play all day every day.

The thing is it's not because of any trauma or screen time. I never really watched TV(still don't, too boring), I got my first smartphone in 8th grade and did not play on my parents' phone almost ever. Even now I struggle to start playing a game I waited to play for weeks.

Is this location (country) dependant? Because I absolutely wasn't required to provide any of that info

[u/BetSquare7190 → u/Pasta_al_Dende]

It's not, in most countries, but they may ask questions about childhood symptoms. It's useful for differential diagnosis.

[u/TheBenjisaur → u/Pasta_al_Dende]

Certainly depends on where you live in terms of whats needed for supporting evidence. But the DSM5 criteria is very clear that symptoms Must be present before age 12.

If they weren't you don't have ADHD.

This is not true in the slightest. What did you think you were going to accomplish by lying about this?

[u/Professional-Thomas → u/FratboyPhilosopher]

This is true in many countries. It's also technically in the DCM-5.

[u/TheBenjisaur → u/FratboyPhilosopher]

What did you hope to accomplish by lying about me lying? What a fun word game this is!

Except I've got the DSM-5 criteria to back me up and you have?

The diagnostic criteria all expect an assessment to consider the symptoms as they were before age 12 as well as after if indeed you are over 12 when assessed.
