Short-term memory loss refers to the inability to retain information for a brief period, typically lasting from a few seconds to a few minutes. This condition can affect daily activities, making it difficult to remember recent conversations, appointments, or tasks. It may result from various factors, including stress, fatigue, or medical conditions such as Alzheimer's disease. Common causes of short-term memory loss include head injuries, medications, and substance abuse. While it can be temporary, persistent issues may require medical evaluation. Treatment options often focus on addressing underlying causes and improving cognitive function through strategies like memory exercises and lifestyle changes.
