Aims:
The aim of the study was to review and describe the Alcoholic Pellagra Encephalopathy, a severe neuropsychiatric condition caused by a combination of niacin (vitamin B3) deficiency and alcohol abuse.
Methods:
PsychInfo, Medline and Embase databases were searched for peer-reviewed studies addressing this illness.
Results:
A historical and conceptual review of the psychopathological aspects of this condition is offered, followed by the report of a patient with a history of chronic alcohol consumption showing signs of pellagra, delusions and visual hallucinations, which was treated successfully with niacin.
Conclusion:
Pellagra encephalopathy should still be considered in the differential diagnosis of acute psychotic disorders seen in the context of chronic alcoholism.
