Hi there and thanks so much for posting this question. Unfortunately this is not my specialty and I would suggest you to post in the Neurology forum where they could help you more.
In any case I would just mention one thing:
I used to train someone with Epilepsy where his attacks where would be so intense that he would lose consciousness with some bladder control.
He used to use moderate physical activity to regain control and he would know when this attacks were going to happen. Then a Neurologist helped him identify where these seizures where taken place in the brain and helped to remove them through surgery
I would provide some information however:
According to the Mayo Clinic
Because epilepsy is caused by abnormal activity in brain cells, seizures can affect any process your brain coordinates. A seizure can produce:
A staring spell
Uncontrollable jerking movements of the arms and legs
Loss of consciousness or awareness
According to the same article
Tonic-clonic seizures (also called grand mal). The most intense of all types of seizures, these are characterized by a loss of consciousness, body stiffening and shaking, and sometimes loss of bladder control or biting your tongue.

Sound exactly thw same as me and I have epilepsy and something called postural orthestatic tachycardia syndrome (also known as POTS to moat doctors) I only found out it was this because I went to specialists. You need to tell them to go to a good neurologist.
Thanks for your comment and suggestion!
