A common misnomer about adhd brains is that they're wired, but really they're actually super tired brains, trying desperately to wake themselves up by flooding adrenalin and cortisol in place of desperately and dangerously low dopamine, (which is actually the petrol that gets you around, not just a carrot at the end of the ride). So when a super tired brain that's overly flooded with adrenalin, gets enough stimulus to produce enough dopamine, it let's go of the adrenaline, mops it all up and can finally rest. Think of those nights you tried to stay awake with teenage friends and caffeinated yourself silly and everyone got all loud and weird. That, but all the time.
Anecdotes are sources of data. The compilation of multiple anecdotes can lead to hypotheses, which are then tested. If you get enough anecdotes, they can become a compelling form of data. The validity of the data is then dependent on the suitability of the anecdote in relation to the subject matter and the opportunities for triangulation. People who make statements like this do not understand how data works.
I read a study that says people with sleep disorders are more likely to be diagnosed with ADHD and vise versa. Not just insomnia either. Narcolepsy, Insomnia, Restless Leg Syndrome, Sleep Apnea…all of em.
Suggests they are tied together. My doctor says one can cause the other so it comes down to the chicken or the egg when diagnosing.
That wouldn't surprise me. I have always been a night owl and maybe slightly non-24. I can get up early, but a single late night will destroy my schedule as my body reverts to that and takes days or weeks to recover.
