In a vivid 1969 study, half of intoxicated participants forgot seeing a toy just 30 minutes earlier, despite recalling it minutes before. Ethanol disrupts the physical changes in brain cells required for storing memories, especially in the hippocampus. While its short-term effects fade within a day, repeated heavy drinking can cause lasting damage.
