Alzheimer’s Disease


Alzheimer’s disease is a form of dementia, a disease that is characterized by cognitive and behavioral problems. As the most common form of dementia, Alzheimer’s affects as many as 5 million Americans, mostly older adults, and is one of the top 10 leading causes of death in the United States. People with Alzheimer’s may experience confusion and have problems involving memory, language, and recognizing family and friends—all which impact their ability to carry out daily activities.Although it’s possible for Alzheimer’s to develop in younger individuals (early onset Alzheimer’s), it usually begins after age 60. Even though the risk of Alzheimer’s increases with age, it’s not a normal part of aging.

What Causes Alzheimer’s Disease?

There is no known specific cause of Alzheimer’s. It’s likely caused by several factors. Age is a risk factor, and this risk doubles every five years after age 65. Genetics may also play a role in the development of Alzheimer’s, and education, diet, and environment are also being studied as potential risk factors. Certain heath conditions may also be linked to Alzheimer’s; these include the same risk factors for heart disease and stroke (high blood pressure and high cholesterol).

What Are the Symptoms?

Symptoms of Alzheimer’s include:

  • Memory problems
  • Confusion
  • Trouble recognizing family and friends
  • Mood and personality changes (agitation, anxiety, anger, or depression)
  • Getting lost or wandering
  • Taking longer to complete regular tasks or inability to complete them
  • Hallucinations, delusions, and paranoia
  • Sleeplessness

Diagnosing Alzheimer’s

Alzheimer’s can only be definitively diagnosed after death with an autopsy. Doctors will instead make a diagnosis of “possible” or “probable” Alzheimer’s. Steps used to make these diagnoses include:

  • Information about overall health, past medical problems, ability to carry out daily activities, and changes in behavior and personality
  • Tests of memory, problem solving, attention, counting, and language skills
  • Medical tests such as blood, urine, or spinal fluid tests
  • Brain scans such as computed tomography (CT) scan or magnetic resonance imaging (MRI)

How Is It Treated?

There is no cure for Alzheimer’s and no treatment to slow its progress, but there are several FDA-approved drugs used to treat symptoms. By treating symptoms, some individuals are better able to carry out the activities of daily life, as these medicines can help them maintain thinking, memory, or speaking skills. FDA-approved drugs for symptoms of Alzheimer’s include Aricept® (donepezil), Exelon® (rivastigmine), Reminyl® (galantamine), and Namenda® (memantine).

Certain lifestyle factors may also help manage symptoms of Alzheimer’s. These include diet, physical activity, social engagement, and mentally stimulating pursuits.

Living with Someone with Alzheimer’s

Caring for an individual with Alzheimer’s can be very challenging. As caregiver, your burden may be physical, emotional, and financial. It’s therefore important to find personal support and resources that will educate you and help you deliver safe and effective care.

Support groups can be helpful for caregivers. You can share concerns, experiences, and tips as well as ask questions and find emotional comfort. The Alzheimer’s Association (, other national organizations (see Resources below), as well as local organizations offer in-person support groups, and support groups can also be accessed online.

Effective coping skills can help you with daily activities like dressing, bathing, and eating that can become very difficult with a person who has Alzheimer’s. Some general tips for caring for a person with Alzheimer’s include:

  • Ask the doctor questions about Alzheimer’s disease, treatment, and lifestyle factors that can help your loved one feel more comfortable.
  • Develop a routine to help things go more smoothly. This may involve choosing to do certain activities—like bathing—when your loved one is less confused, more cooperative, and functioning better. A schedule for activities such as dressing can help the day go more smoothly, as the person can expect a routine.
  • Consider using adult day care in order to give yourself a break.
  • Learn how to best communicate with your loved one. Simple words, short sentences, and a calm tone may help. Make eye contact. Gently help him or her find a word he or she is searching for or complete a thought.
  • Make safety adjustments in the home, such as secure locks (especially if wandering is a risk), no-slip mats and handrails in the bathtub or shower, and good lighting.
  • Make sure that your loved one always carries a form of identification or wears a medical bracelet.
  • When it’s no longer safe for your loved one to drive, make sure that he or she doesn’t have access to a car or car keys.
  • Know when it’s not safe to leave your loved one alone and never do so in those circumstances—such as in the bath or around kitchen appliances.
