Everyone occasionally experiences forgetfulness. Mild memory loss tends to increase with age and is generally no cause for concern. But progressive memory loss due to illnesses like Alzheimer’s disease can be serious.

Consult your doctor if memory loss starts to affect your daily life, or if it’s accompanied by other symptoms. Noting what type of memory loss you have will help your doctor determine its cause.

Many causes of memory loss are treatable if diagnosed early. If not diagnosed and treated, some illnesses will progress and make treatment more difficult.

As you age, you may find that you have memory lapses from time to time. You may forget the name of someone you just met, or you may misplace things more often. Perhaps you rely more on lists and calendars to remember chores and appointments. Memory loss from normal aging doesn’t affect your ability to function at work or at home.

Coping with Your Own Memory Loss

If your memory is not as sharp as it once was, a few simple adjustments can help you with your daily activities.

  • Use lists for chores.
  • Keep a checklist of medications and when they
    should be taken. Some people find “pill sorters” helpful. You can purchase
    these at your local pharmacy, and they will help you remember whether or not
    you took your medication.
  • Keep your address book and calendar up to date.
  • Keep your home organized and easy to manage.
  • Be socially active and engage in hobbies you
  • If your memory loss is progressing or becoming
    severe, make an appointment with your doctor. Ask someone you trust to go with

  • Keep important items in plain sight.
  • Use sticky notes around the house as reminders
    of how to perform tasks.
  • Encourage them to remain socially active.
  • Use photographs and familiar belongings to spark
  • Arrange to have someone help in the home. If
    memory loss is severe, investigate home health care, assisted living, or nursing
    home options.
  • Be patient. Don’t take someone else’s memory
    loss personally — remember that they can’t help it.

Many factors can cause memory loss. These factors include:

  • vitamin B-12 deficiency
  • sleep deprivation
  • use of alcohol or drugs and some prescription
  • anesthesia from recent surgery
  • cancer treatments such as chemotherapy,
    radiation, or bone marrow transplant
  • head injury or concussion
  • lack of oxygen to the brain
  • certain types of seizures
  • brain tumor or infection
  • brain surgery or heart bypass surgery
  • mental disorders such as depression, bipolar
    disorder, schizophrenia, and dissociative disorder
  • emotional trauma
  • thyroid dysfunction
  • electroconvulsive therapy
  • transient ischemic attack (TIA)
  • neurodegenerative illnesses such as Huntington’s
    disease, multiple sclerosis (MS), or Parkinson’s disease
  • migraine

Some of these conditions are treatable and, in some cases, memory loss can be reversed.


Progressive memory loss is a symptom of dementia. Other symptoms include difficulty with reasoning, judgment, language, and thinking skills. People with dementia can also exhibit behavioral problems and mood swings. Dementia usually starts gradually and gets more noticeable as it progresses. Dementia can be caused by a variety of diseases, the most common of which is Alzheimer’s disease.

Alzheimer’s Disease

Alzheimer’s disease impairs memory and affects reasoning, judgment, and the ability to learn, communicate, and perform everyday functions. People with Alzheimer’s disease can quickly become confused and disoriented. Long-term memories are usually stronger and last longer than memories of recent events. Although it can strike earlier, this progressive disease generally affects people over age 65.

Consult your doctor if memory loss is interfering with your daily activities, threatening your safety, progressing, or accompanied by other physical symptoms.

Memory loss can be caused by a variety of diseases and conditions that may worsen if left untreated.

A medical exam for memory loss will include a complete medical history. Bring a family member or trusted friend along to help you. Your doctor will ask questions about the specifics of your problems with memory. They may also ask a few questions to test your memory. Your doctor should also give you a complete physical exam and ask about other physical symptoms.

Depending on the findings of the exam, your doctor may refer you to a specialist, such as a neurologist, geriatrician, or mental health professional. Additional tests may include:

  • cognitive testing to check your thinking ability
  • blood tests to look for various conditions
    including vitamin B-12 deficiency and thyroid disease
  • imaging tests such as magnetic resonance imaging
    (MRI) or computed tomography (CT) scan
  • electroencephalogram (EEG) to measure the
    electrical activity of the brain
  • spinal tap
  • cerebral angiography, which is an X-ray to see
    how blood flows through the brain

Getting a diagnosis is an important first step. Many medical conditions that cause memory loss are treatable when identified early.
