This study investigated the diagnostic value of proton magnetic resonance spectroscopy (MRS) findings in temporal lobe epilepsy (TLE). 24 patients whose neurologic examinations revealed TLE were examined by EEG, magnetic resonance imaging (MRI) and MRS and ten healthy volunteers by MRI and MRS. In the patient group, EEG abnormalities were seen in 15 cases, MRI abnormalities in 12 and MRS abnormalities in 17. In 14 patients, MRS lateralized the seizure focus. MRS is an effective modality for demonstrating temporal lobe abnormalities and contributes to lateralization of the epileptic focus.
