i read an interesting article on epilepsy yesterday and it transpires thare are similarities between it and dp/dr.
an epileptic will experience an aura before a fit,a sence of deja vu,familiarity,apprehension,unreality.it isnt as troubling as the dp/dr suffered by people with comorbid psychiatric disorders.
the one massive psychological similarity between epileptics and dp/dr sufferers is the anticipatory angst felt while fearing another fit,and not knowing when or where it will happen.
in terms of the neurological similarities between the two,im sure some but not all dp/dr sufferers have convulsive tendencies in their temporal lobes,albiet not as severe as a full on seizure.
what i have learned and deduced from this,as a lay man and not as a doctor,is anticipatory angst seems to be the principal problem,not the actual neurological condition.this fear,once out of control can hold anyone to randsom,epileptic,psychiatric or otherwise.
