Longstanding episodes: focal seizures vs functional/dissociative? Looking for people with similar experiences
I've had stereotyped episodes since childhood (~30 years). They usually start with déjà vu, then chest tightness/heat/sweating and sometimes nausea, followed by about 2–4 minutes where my recent memory seems impaired. I'm awake and can talk, but I may repeat myself, forget parts of conversations, or get confused about the date/location. Afterwards I'm usually disoriented/headachy and often don't remember the episode well.
I've had multiple normal routine/ambulatory EEGs and a normal-ish MRI. Several antiseizure medications haven't meaningfully reduced the episodes.
I'm trying to understand whether people with focal/temporal seizures OR functional/dissociative seizures recognize this pattern.
If you've experienced something similar, what was your eventual diagnosis, and what happened when you had a typical episode captured on video EEG?
