Memory loss

Definition

Memory loss is unusual forgetfulness. You may not be able to remember new events, recall one or more memories of the past, or both.

The memory loss may be for a short time and then resolve (transient). Or, it may not go away, and, depending on the cause, it can get worse over time.

In severe cases, such memory impairment may interfere with daily living activities.

Causes

Normal aging can cause some forgetfulness. It is normal to have some trouble learning new material or needing more time to remember it. But normal aging does not lead to dramatic memory loss. Such memory loss is due to other diseases.

Memory loss can be caused by many things. To determine a cause, your health care provider will ask if the problem came on suddenly or slowly.

Many areas of the brain help you create and retrieve memories. A problem in any of these areas can lead to memory loss.

Memory loss may result from a new injury to the brain, which is caused by or is present after:

• Brain tumor

• Cancer treatment, such as brain radiation, bone marrow transplant, or chemotherapy

• Concussion or head trauma

• Not enough oxygen getting to the brain when your heart or breathing is stopped for too long

• Severe brain infection or infection around the brain

• Major surgery or severe illness, including brain surgery

• Sudden, temporary loss of memory (transient global amnesia) of unclear cause

• Transient ischemic attack (TIA) or stroke

• Fluid collection in the brain (hydrocephalus)

• Multiple sclerosis

• Dementia

Sometimes, memory loss occurs with mental health problems, such as:

• After a major, traumatic or stressful event

• Bipolar disorder

• Depression or other mental health disorders, such as schizophrenia

Memory loss may be a sign of dementia. Dementia also affects thinking, language, judgment, and behavior. Common types of dementia associated with memory loss are:

• Alzheimer disease

• Vascular dementia

• Lewy body dementia

• Fronto-temporal dementia

• Progressive supranuclear palsy

• Normal pressure hydrocephalus

• Creutzfeldt-Jakob disease

Other causes of memory loss include:

• Alcohol or use of prescription or illegal drugs

• Brain infections such as Lyme disease, syphilis, or HIV/AIDS

• Overuse of medicines, such as barbiturates, opioids or hypnotics

• Electroconvulsive therapy (ECT) most often causes short-term memory loss

• Epilepsy that is not well controlled

• Illness that results in the loss of, or damage to brain tissue or nerve cells, such as Parkinson disease, Huntington disease, or multiple sclerosis

• Low levels of important nutrients or vitamins, such as low vitamin B1 or B12

Home Care

A person with memory loss needs a lot of support.

• It helps to show the person familiar objects, music, or and photos or play familiar music.

• It is important to write down when the person should take any medicine or do other critical tasks.

• If a person needs help with everyday tasks, or if safety or nutrition is a concern, you may want to consider extended-care facilities, such as a nursing home.

What to Expect at Your Office Visit

Your provider will perform a physical exam and ask about the person's medical history and symptoms. This will usually include asking questions of family members and friends. For this reason, they may be interviewed in-person or by phone.

Medical history questions may include:

• Type of memory loss, such as short-term or long-term

• Time pattern, such as how long the memory loss has lasted or whether it comes and goes

• Things that triggered memory loss, such as head injury or surgery

Tests that may be done include:

• Blood tests for specific diseases that are suspected (such as low vitamin B12 or thyroid disease)

• Cerebral angiography

• Cognitive tests (neuropsychological/psychometric tests)

• CT scan or MRI of the head

• Electroencephalogram (EEG)

• Lumbar puncture

• Positron emission tomography (PET) scan

• Genetic tests

Treatment depends on the cause of memory loss. Your provider can tell you more.
