"LTC" also makes a crappy "syndrome" in the sense that a syndrome is supposed to be a fairly neat collection of symptoms, whereas anybody who has any adverse effects after E seems to pool it under "LTC" when their symptoms could fit under established diagnoses (e.g. depression/anxiety/depersonalization) and be treated under that
Persisting brain zaps are rather odd and are relatively confined to these E/SSRI issues, but even HPPD symptoms can arise with a cranial nerve condition like occipital neuralgia (which can be treated with lidocaine injections onto those cranial nerves, but one would never think that if all they're thinking is LTC LTC LTC, brain is fried). I think people misdirect their doctors when they tunnel vision on the E, sometimes they immediately become headcases
Lots of people use E, lots of people develop neurological conditions, eventually those two will intersect
