ABSTRACT
The patient had a history of seizures since the age of 16 years (etiology and type unknown) and had been well controlled on phenobarbital and phenytoin since then. His seizures consisted of arm and leg shaking with loss of consciousness and occasional incontinence. Six months before admission, he slipped down some stairs and sustained head trauma with loss of consciousness for 10 minutes. At that time, he did not seek medical attention because he felt well. Over the ensuing 6 weeks, the patient developed increasing lethargy, memory impairment, decreased sensation on the right side of his body, headache and visual impairment.
