Thank you for posting your query.
The first seizure
in your friend needs to be investigated, to find out the underlying cause of his seizure. Identification and treatment of the underlying cause could prevent the recurrence of seizure in the future.
Evaluation would include doing a brain scan (CT or MRI
of brain), electroencephalography
(EEG), blood tests (sugar, calcium, sodium, etc) and screening for toxic substances or drugs.
If his MRI or EEG shows any abnormality, then, long term anti epileptic drugs may be required.
Confusion and memory impairment may occur following a generalized seizure. It usually lasts for 1-2 days, but may last longer in some people.
Please show him to a neurologist
I hope it helps.
