Niemann-Pick disease type C (NPC) is a neurometabolic genetic disorder that is distinguished from Niemann-Pick disease by its later onset, more insidious progression, variable visceromegaly, and abnormalities of intracellular cholesterol metabolism. We describe a patient who presented with an 8-year history of psychosis requiring chronic neuroleptic therapy for a presumed diagnosis of schizophrenia. He was subsequently diagnosed with NPC as the emerging features of dementia, ataxia, dysarthria, and vertical supranuclear ophthalmoplegia were recognized. The characteristic features of adult-onset NPC and the obstacles to early diagnosis are reviewed.

Clinically, we most often associate Wernicke's encephalopathy (WE) with an alcohol abusing population. However, it is important to consider other causes of malnutrition and vitamin deficiency as risk factors for the development of this disorder. We present a case of a 51-year-old man with schizophrenia and malnutrition who presented with delirium, ophthalmoplegia, and seizures. He responded rapidly to the administration of IV thiamine. Because of the high rate of mortality and morbidity, WE should be high on the differential of any patient at risk for malnutrition or with ophthalmoplegia, regardless of alcohol history. This is particularly important in psychiatric patients where the syndrome may be masked and thus treatment delayed.

While Wernicke's encephalopathy (WE) is a well-characterized syndrome in alcoholism and malnutrition, little is written of its prevalence or presentation in patients with psychiatric illness. We present a case of a 37-year-old Nigerian male with schizophrenia and malnutrition who presented with delirium and ophthalmoplegia. The clinical diagnosis was supported by dramatic reversal of the symptoms and signs following the administration of intravenous thiamine. Owing to the high rate of mortality and morbidity, WE should be considered in the evaluation of any patient with unexplained nystagmus, gaze palsies, gait ataxia, or confusion, especially if a condition associated with malnutrition is present. This is particularly important in psychiatric patients where the clinical history and syndrome may be obscured and treatment delayed.
