Abstract
AbstractAn 82‐year‐old woman presented with a complaint of sudden difficulty in chanting the Heart Sutra because visual hallucinations of Tetris‐like color blocks disturbed the image of the Sutra in her mind. Neuropsychological examination revealed transient impairment of visual memory recall with hallucinations. Physical examination showed no abnormalities except mild hypertension. She was alert, oriented with normal motor, sensory, and cerebellar function. She was diagnosed with mid‐temporal lobe seizures based on electroencephalography and single‐photon emission computed tomography (SPECT) findings. Subtraction ictal SPECT co‐registered to MRI (SISCOM) examination was useful in detecting the seizure focus. Symptoms resolved completely after the administration of antiepileptic drugs. This case report provides new insights into the mechanism of visual memory recall.
