Alcohol consumption can lead to memory loss. According to [2], alcohol affects the hippocampus, which is responsible for forming new memories. Alcohol can impair the ability of the hippocampus to create new memories and also affect the brain's ability to recall existing memories. Long-term alcohol abuse can lead to permanent damage to the hippocampus, resulting in chronic memory problems. In addition, alcohol abuse can lead to thiamine deficiency, which can also cause memory loss [3]. Thiamine is an essential nutrient that helps the brain function properly, and alcohol can interfere with its absorption. According to [1], alcohol is a depressant that slows down the central nervous system, which can lead to a range of cognitive impairments, including memory loss. While moderate alcohol consumption may not have a significant impact on memory, excessive alcohol consumption can lead to blackouts, where the individual is unable to recall events that occurred while they were intoxicated [2]. In conclusion, alcohol consumption can lead to memory loss, especially in cases of long-term abuse and excessive consumption.
