[Clinical judgment and decision making in clinical practice. A music conductor with epilepsy followed by memory...

A 40-year-old conductor was admitted because of increasing drowsiness and confusion. Two years before admission he had had a first seizure. One year before admission he had a generalized convulsive status epilepticus; the following months he was less able to concentrate. A second status epilepticus was followed by transient weakness of his left arm and a depressed level of consciousness for several weeks. After awakening, he had delusions, and his wife found him demented. In the following months his confusion and drowsiness gradually deteriorated. He had previously had gonorrhoea, an episode of fever and exanthema, and was found to have oligospermia as cause of his infertility. On examination he was disoriented, and he had dysarthria. His left pupil was smaller, but both pupils reacted normally. There was left hemianopia and cerebellar ataxia. CT and MR showed large ventricles and periventricular diffuse lesions in the white matter. CSF examination revealed leucocytosis and increased protein content. Further examination were focussed on serological evidence of syphilis, and finally neurosyphilis was diagnosed. After treatment with penicillin, the patient started to recover.
