ABSTRACT
Cryptogenic epilepsy is a group of epilepsy syndromes for which the etiology is unknown but the underlying brain disease is suspected. So the present work aims to study the probable relationship between Toxoplasma gondii and cryptogenic epilepsy. Fifty patient, were selected with cryptogenic epilepsy and 50 patients with known cause of epilepsy in comparision to 50 healthy as control group to investigate the sero-positivity rate for anti-To-Toxoplasma IgG antibody by ELISA. The sero-positiviry rate of anti-Toxoplasma IgG antibodies among cryptogenic epilepsy patients was [20%] and it was higher than healthy controls [2%] and known cause epilepsy patients [4%] with highly significant statistically difference [P< 0.01]. There might be a causal relationship between chronic toxoplasmosis and cryptogenic epilepsy
