Epilepsy research and treatment

Four 51-year-old monozygotic quadruplets concordant for schizophrenia, originally studied at the National Institute of Mental Health 25 years ago, were restudied with topographic electroencephalography (EEG), evoked potentials (EPs), computed tomography (CT scans), polysomnographic sleep recordings, and positron emission tomography (PET) with 18F-2-deoxyglucose. EEG and EP findings were consistent with those from other groups of patients with schizophrenia and showed great similarity within the quadruplets. CT scans revealed uniformly small lateral ventricles. PET scans replicated earlier findings of relatively low glucose use in the frontal lobes but did not show strong familial concordance.
