What is Alzheimer’s Disease?

By Cheryl Theriault

Alzheimer’s Disease is defined as a progressive, degenerative disease that attacks the brain and impacts memory, thinking, and behavior. It is the most common form of dementia. Dementias affect people’s memory, thinking ability, their ability to care for their daily activities of living. Alzheimer’s disease ultimately results in death and is the fourth leading cause of death in adults. The leading three causes of death in adults are heart disease, cancer, and stroke. Alzheimer’s usually occurs in persons 65 years of age or older but can begin when people are in their 40s or 50s.

Symptoms of Alzheimer’s disease include forgetfulness, decreased capacity to manage daily activities of living such as bathing, dressing, shopping, meal preparation, medication management, bill paying, etc. There can be personality changes including reclusiveness, paranoia, and aggressiveness. Frequently persons with Alzheimer’s disease are disoriented, have trouble with language skills, and lose the ability to use good judgment, follow steps, and problem solve.

The progression of the disease varies from person to person but the average time from onset to death is eight years. This is just an average range and the span between onset to death has been as little as three years and as long as twenty years. Some warning signs include:

  • Recent memory loss that affects job skills or ability to drive
  • Difficulty performing familiar tasks
  • Language skill problems
  • Disorientation regarding time and place
  • Poor judgment
  • Problems with abstract reasoning
  • Misplacing things
  • Changes in mood and/or behavior
  • Changes in personality
  • Loss of initiative

It is extremely important to note that sudden onset of any or all of the above symptoms might reflect some reversible medical trauma the individual is suffering. This can be as simple as a urinary tract infection, side effects or a new medication, the body’s reaction to the trauma of a fall. Therefore the first course of action is to get immediate medical attention to see if there is a treatable, reversible medical event going on.

Diagnosing Alzheimer’s disease continues to be elusive. A detailed medical evaluation must take place and should include:

  • lab work
  • medical history
  • neurological testing
  • mental status assessments
  • a thorough physical examination.

A diagnosis is usually arrived at by first ruling out all other possible causes however confirmation of the diagnosis requires examination of brain tissue which is done by autopsy.

There are no treatments to “cure” Alzheimer’s disease. There are medications that can slow the progression. There are interventions that can be developed to deal with physical, mental, and behavioral changes. There is advance planning that can take place in the form of getting final affairs in order while the Alzheimer’s victim can still execute legal documents such as Power of Attorney, Health Care Power or Attorney, Living Will.

Educating the caregivers and family is an important step in coping with the changes that are occurring. Dealing with difficult behaviors, maintaining a calm, comfortable routine, how to include social activities and maintain adequate hygiene and nutrition are all important skills that must be learned.

Many people find adult day programs to be an excellent source of specialized socialization. Raleigh has even developed a Saturday and evening program (for people who become restless and wander and pace as the night hours approach).

If you hear people talk about the “stages” of Alzheimer’s disease the following provides a brief summary:
