PURPOSE: Cryptogenic epilepsy, defines a group of epilepsy syndromes for which an aetiology is unknown but an underlying brain disease is suspected. We selected patients in this subgroup of epilepsy and investigated the sero-positivity rate for anti-Toxoplasma IgG antibodies by Enzyme Linked Immunosorbent Assay (ELISA). We investigated the probable relationship between Toxoplasma gondii and cryptogenic epilepsy. METHODS: We selected 50 patients with cryptogenic epilepsy, 50 patients with known cause epilepsy and 50 healthy volunteers and investigated the sero-positivity rate for anti-Toxoplasma IgG antibodies by ELISA. RESULTS: The sero-positivity rate for anti-Toxoplasma IgG antibodies among cryptogenic epilepsy patients (52%) was found to be higher than healthy volunteers (18%) and known cause epilepsy patients (22%) with statistical significance, (X(2)=18.095, P<0.01). CONCLUSION: There might be a causal relationship between chronic toxoplasmosis and the aetiology of cryptogenic epilepsy
