Most of these conditions can be treated. Your doctor can screen you for conditions that cause reversible memory impairment, says the Mayo Clinic.
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.
