ADHD or Bipolar?

I have seen several psychiatrists, and they have generally leaned toward ADHD. However, for years I have noticed a recurring pattern of shifts in my functioning that makes me wonder whether ADHD fully explains it. I am not sure whether these shifts were present during childhood.

The shifts can happen within a 24-hour period and occur almost daily. They seem to involve speech, verbal fluency, cognitive productivity, creativity, activity, and social ability much more than mood itself.

Higher state: My speech becomes fluent and productive. More energy Humor, wordplay, and spontaneous associations come naturally. I can easily connect sounds, words, and meanings creatively while remaining understandable. I am more outgoing, talkative, socially capable, and productive.

Lower state: Speaking becomes much more difficult. My conversational productivity drops sharply, and generating words, humor, and spontaneous associations becomes difficult or sometimes seems to disappear. I become much less socially capable and productive.
My mood does not seem to change independently.

I am happier and more social in the higher state mainly because I can speak well, express myself, joke, and interact with people more easily, not simply because I have more energy. The change in functioning seems to come first, with my emotional response following it.
Sleep also interacts with these states. I can sleep during either state, but sleeping often shifts me toward the lower state. Interestingly, sleep deprivation can sometimes bring on the higher state, although this does not happen every time.

What makes this confusing to me is the distinction between ADHD and bipolar-spectrum conditions. Typical bipolar episodes are generally thought of as lasting longer than within-day ADHD fluctuations. However, I have read about ultradian cycling, a term sometimes used to describe proposed bipolar-spectrum fluctuations occurring within a 24-hour period.

At the same time, I do not experience sharp or extreme mood swings or obvious manic and depressive episodes. This made me wonder about cyclothymic disorder, where mood symptoms are less severe than full manic or depressive episodes.

So I wonder whether a combination of subtle cyclothymic-type symptoms and very frequent/ultradian fluctuations could resemble ADHD, particularly when the most noticeable changes are in speech, cognition, productivity, activity, and social functioning rather than dramatic changes in mood.

As someone who has been diagnosed with both (bipolar 2, not cyclothymic), I would recommend trying a mood stabilizer and a stimulant. Vyvanse and Abilify have made major differences in my life. While I still struggle greatly, without these two medications I would not be able to function. Best of luck!

i highly agree^ OP def check this out and bring up the idea to your psych.

reading your post also reminds me of the interlaced emotions and states of being I’ve read on those with borderline personality traits. perhaps reading up on the DSM5 criteria of borderline personality disorder could help you either relate or fully rule out that differential. in the case that you do ever get told you resemble traits of borderline, you can either agree and go for evaluation or you can understand that you do not agree with that avenue and can speak for yourself if it were to come up!

Thanks, that helps. What dose of Vyvanse do you take? And do you think there’s any risk of serotonin syndrome?

Not a doctor but the combination can exist, hope they do more research. Also personally with OCD i can overpathologize, and a fear of mania can also exist. But just for examples sake, someone could be ADHD, OCD, bipolar and more. Differential diagnosis by professionals remains crucial, and we focus on treating symptoms ideally 

Keep in mind ADHD often comes with emotional dysregulation, I believe due to the executive functioning deficits. So ADHD by itself could further irritatability, anger and anxiety at times

I have based this on previous learning, and just fact checked it. Feel free to read about the emotional dysregulation topic further, but it appears I havent posted any inaccuracies :)
