For a recurrent fainting
episode, the possibility of seizure
is strong. The description of the fainting by you and by somebody who saw you at that time helps the neurologist
most in arriving a diagnosis of seizure. The details would typically include any abnormal feelings before you fainted, duration of loss of consciousness
, position of your hand and legs during fainting, any problems when you recovered etc etc. If you could give all these details and the doctor was satisfied, then probably diagnosis of seizure is true. Other tests including EEG are only supplementary and can remain normal in a sizable number of patients with seizures. I hope your query is solved.
