Answer is A (Hepatic encephalopathy): Symmetric, high voltage, triphasic slow wave (2-5/second) fattern on Electroencephalogram (EEG) is characteristic (hut non specific) of hepatic encephalopathy- Harrison 16th/1868 The diagnosis of hepatic encephalopathy should be considered when four major factors are present Acute or chronic hepatocellular disease and/or extensive poal systemic collateral shunts Disturbance of awareness and mentation which may progress from forgetfulness and confusion to stupor and finally coma. Shifting combinations of neurological signs including asterixis, rigidity, hyperreflexia, extensor plantar signs and rarely seizures.
