[A case of temporal lobe epilepsy with recurrent dysphasic seizures].

We reported a 40-year-old right-handed female with temporal lobe epilepsy manifesting recurrent dysphasic seizures. At age 25, the patient developed a complex partial seizure, who subsequently showed frequent auditory seizures that often evolved to complex partial or secondarily generalized seizures at age 25-27, and dysphasic seizures (DSs) at age 27 -40. DSs were characterized by total aphasia without impairment of consciousness, which were often accompanied by functional hallucination. Brain CT, cerebral angiography, and brain MRI demonstrated no abnormal findings. At age 39 (May 20, 1989), recurrent aphasic state was unexpectedly observed during medical examinations. An EEG was performed immediately, and the EEG seizure pattern (duration: ca. 8-17 sec) in which 15 -16 Hz spikes began in the left posterior temporal region and spread rapidly to the left midtemporal, inferior frontal, and central regions was detected 14 times within 30 minutes. During the seizure patterns, the patient was aphasic.
