We report a 37-year-old man who presented memory loss, homonymous right hemianopsia, and elevation of anti-herpes simplex antibody titer. He had an auto accident in January 1992 in that the car he was driving slipped down a 3m slope; his car was severely damaged, however, he himself was not injured. Shortly after this accident, he went out of his house less often than before, and he noted some difficulty in his vision.
