Wernicke encephalopathy is the first, acute phase and Korsakoff psychosis is the long-lasting, chronic stage.
Patients with this condition have the sudden onset of Wernicke encephalopathy; the symptoms include marked confusion, delirium, disorientation, inattention, memory loss, and drowsiness.
Wernicke's syndrome, also known as Wernicke encephalopathy, is a neurological disease characterized by the clinical triad of confusion, the inability to coordinate voluntary movement (ataxia), and eye (ocular) abnormalities.
Because some patients in coma are malnourished and susceptible to Wernicke encephalopathy, thiamin 100 mg IV or IM should be given routinely. If plasma glucose is low, patients should be given 50 mL of 50% dextrose.
In most societies, however, thiamine deficiency is largely associated with excessive alcohol use. One manifestation is Wernicke encephalopathy (E51.2); another is peripheral neuropathy, and the two may occur together .
