When assessing a client with chronic alcoholism, reviewing serum levels of which vitamin can address memory dysfunction?

Thiamine, also known as vitamin B1, is crucial for proper brain function, and its deficiency is particularly relevant in individuals with chronic alcoholism. Chronic alcohol consumption often leads to malnutrition and impaired absorption of vital nutrients, including thiamine. This deficiency is linked to serious neurological conditions, most notably Wernicke's encephalopathy, which can present as memory dysfunction, confusion, and other cognitive impairments.

Assessing serum levels of thiamine can provide insight into a client’s nutritional status and the risk or presence of these cognitive issues. Supplementation of thiamine is an essential part of treating individuals with alcohol use disorder, as it can help alleviate symptoms of cognitive dysfunction and prevent permanent damage. Other vitamins mentioned do not have the same direct correlation with memory dysfunction specifically in the context of chronic alcoholism, making thiamine the appropriate focus for evaluation and intervention.
