Memory loss, or amnesia, is the inability to remember past events or information, affecting either short-term or long-term memory. Causes include aging, head injuries, neurological disorders like Alzheimer's disease, medical conditions, psychological stress, and substance abuse. Symptoms range from mild forgetfulness to severe memory impairment. Treatment focuses on addressing underlying causes, using medications, cognitive therapy, lifestyle changes, and stress management to improve memory and quality of life.
