A 53-YEAR-OLD man was admitted with a 2-day history of odd behavior and increased drowsiness. On the day of admission he suddenly lost the ability to speak. He also had a 3-month history of lethargy, abdominal pain, and weight loss, which had been investigated by his general practitioner. The only abnormality found was a plasma viscosity of 2.27 mPas (normal, 1.25-1.72 mPas). He smoked 20 cigarettes per day. The remainder of the history was unremarkable. On admission he was pyrexial (temperature, 38.0°C) and tachycardic with a global aphasia without hemiparesis. There were no other abnormalities: in particular the findings of cardiovascular examination were normal.
