Paroxystic neuropsychological symptoms as the early expression of hepatic encephalopathy. A case report.
A 52-year-old patient presented with paroxystic episodes of generalized apraxia, anomia, agraphia and acalculia. The transient character of these attacks was supported by several neuropsychological examinations. Initially a tentative diagnosis of multiple TIA's was made. Treatment consisted of antiplatelet aggregation therapy. Three years later, however, paroxystic neuropsychological symptomatology occurred more frequently with an increase of severity. The patient was again seen and the differential diagnosis included epilepsy or a metabolic disturbance, in casu hepatic encephalopathy. A therapeutic trial with carbamazepine was started but the patient deteriorated further. He developed a flapping tremor and became stuporous. The blood ammonia was high and there were triphasic waves on the EEG. A probable diagnosis of hepatic encephalopathy was made and carbamazepine therapy was withdrawn. There was a good response on low protein diet and lactulose.
