In epileptics, valproic acid is used to control absence seizures[?], tonic-clonic seizures[?] (grand mal[?]), complex partial seizures[?], and the seizures associated with Lennox-Gastaut syndrome[?].

Valproate is believed to affect GABA receptors in the human brain.

There have also been reports of cognitive dysfunction[?], Parkinsonian syndrome[?] and even pseudoatrophic brain changes[?] in long-term treatment with valproic acid.
