Long-term alcohol use disorder can lead to which of the following pathophysiologic conditions?

Long-term alcohol use disorder can lead to Wernicke-Korsakoff syndrome, which is a serious neurological condition caused primarily by thiamine (vitamin B1) deficiency. Chronic alcohol consumption disrupts the absorption and utilization of nutrients, particularly thiamine, which is essential for brain function. The syndrome consists of two separate but related conditions: Wernicke's encephalopathy, characterized by confusion, ataxia, and ophthalmoplegia, and Korsakoff's psychosis, which involves significant memory disturbances and confabulation.

The development of Wernicke-Korsakoff syndrome underscores the impact that prolonged alcohol use has on brain health and function, specifically the areas of the brain responsible for memory and cognition. Understanding this link is crucial for accurately recognizing and addressing the potential neurological consequences of alcohol abuse, which can significantly affect an individual's quality of life.
