That might be me. At 17, I experienced a powerful sequence of temporal lobe seizures, which were preceeded by the lesser seizure of abdominal aura. I had about 30 epileptic discharges on intervals of 5 seconds over 3 minutes. I was smoking cannabis for the 1st time, and it was all very confusing. I lost my personality, my emotions, developed a head tremor, began experiencing frequent ocular migraine headaches,
developed agoraphobia, and according to literature I would read some 40 years later, I was a worst case scenario as my "post ictal psychosis segued into an affective disorder of major depression". I survived 5 horrible episodes in my lifetime. Despite the severity of my illness, I got little to no help from the US medical community.
One neurologist told me "We have bigger fish to fry" in regards to my ocular migraines. He never offered an EEG which would have shown I was epileptic. After 40 years of dp and major depressive episodes, I solved the riddle of my illness through a British Medical Library where I read a case history of someone who
also suffered a rare and difficult to diagnose epileptic syndrome which featured every unique symptom that I also experienced. At age 57, I ordered the diagnostics (EEG and MRI) which verified my self diagnosis. Sadly, neurology has not made much headway in 40 years. I am no longer experiencing focal seizures. Since having ECT
in 2014, I have been depression free. But the pathology in my temporal lobe is evident on EEG. The neurologist told me "Go to the Social Security Office, you are disabled.". LOL. I'm an honorably discharged Vietnam Era Vet, I set production records at a US Steel Blast Furnace, I worked in the nuclear industry for 5 years and did
another 23 as an electronics technician. My trophy case is full. I'm not bragging so much, but I'm just pointing out that I never quit. I persevered through the darkest of times. I just added the SSDI check to my pension. I got nothing kind to say about mental health providers or the medical industry in general. But, yes....epilepsy and its syndromes can and do cause dp and dr.
Focal temporal lobe seizures are easily confused with panic attacks. I recommend anyone who is experiencing altered states of consciousness (like some panic attacks) get an EEG. If it is negative, you have learned something. If it is positive, it can save you 40 years. 40 years was my entire adult life.
