Brain Injuries Affect Memory

At any age, an injury to the head and brain can cause trouble with somebody’s memory. Some people who recover from brain injuries need to learn old things all over again, like how to talk or tie their shoes.

Abusing alcohol or using illegal drugs is another way to injure the brain and cause memory problems. Hallucinogens (like LSD or PCP) can alter certain chemicals in the brain that actually make memories harder to recall.
