Diálise - demência: estudo eletrencefalográfico de um caso

Abstract

A case of a 65 years-old black man with chronic renal failure, treated with chronic haemodialysis, in which a dialysis dementia syndrome developed is reported. In the initial phase the electroencephalogram had the typical burst of sharp and slow waves, waning with haloperidol and diazepam treatment. The withdrawal of this medication induced reappearance of the symptoms and EEG. abnormalities. As soon as the patient came back to the diazepine (potassium clorazepate), the mental symptoms subsided, but few weeks later he died of a cerebral haemorrhage. The electroencephalographic features are described and a brief comment about this disease is made.
