Reversible causes of memory loss

Many medical problems can cause memory loss or other dementia-like symptoms. Most of these conditions can be treated. Your doctor can screen you for conditions that cause reversible memory impairment.

Possible causes of reversible memory loss include:

• Medications. Certain medications or a combination of medications can cause forgetfulness or confusion.
• Minor head trauma or injury. A head injury from a fall or accident — even if you don't lose consciousness — can cause memory problems.
• Emotional disorders. Stress, anxiety or depression can cause forgetfulness, confusion, difficulty concentrating and other problems that disrupt daily activities.
• Alcoholism. Chronic alcoholism can seriously impair mental abilities. Alcohol can also cause memory loss by interacting with medications.
• Vitamin B-12 deficiency. Vitamin B-12 helps maintain healthy nerve cells and red blood cells. A vitamin B-12 deficiency — common in older adults — can cause memory problems.
• Hypothyroidism. An underactive thyroid gland (hypothyroidism) can result in forgetfulness and other thinking problems.
• Brain diseases. A tumor or infection in the brain can cause memory problems or other dementia-like symptoms.
