Talk to Neuro Physician on Like Seizure Disorders

Since age 14 i experienced a passing out or fainted for the first time. Then another attack took place in 19 and 20 age respectively. After a brief gap in the age of 23. So i have experienced total 4 attempts of passing out. We went through a test of valproic acid and using a medicine of epival and arcalion. Silliver syrup. We want to know what is the root cause and reason. Plus have gone through two EEG tests the result where as follows: A single normal inter-ictal EEG does not by itself rule out seizure disorder. An appropriate clinical Correlation is therefore suggested.
