Persistent interictal aphasia after repeated partial seizures: a case report.

We reported a case of persistent interictal aphasia after repeated partial seizures. This 64-year-old man, left-handed and literate, developed repeated right facial twitching associated with head turning to the right or transient loss of awareness since October 30 1991. Persistent aphasia between seizures occurred from November 4. An electroencephalogram (EEG) on November 6 showed an epileptic focus over the left frontal area. Tc-99m HMPAO brain single photon emission computed tomography (SPECT) performed one and half and hour after an attack on November 7 showed focal hyperperfusion over the left frontal area. The aphasia recovered on November 7 after the seizures had been stopped. Follow-up EEG and Tc-99m HMPAO brain SPECT done on November 11 and November 14 respectively were normal.
