Alzheimer's disease (AD) was first discovered in 1906 by a German doctor named Alois Alzheimer. It is a disorder
of the brain, causing damage to brain tissue over a period of time. The disease can linger from 2 to 25 years before
death results. AD is a progressive, debilitating and eventually fatal neurological illness affecting an estimated 4-5
million Americans. It is the most common form of dementing illness.
Alzheimer's disease is characterized clinically by early memory impairment followed by language and perceptual
problems. This disease can affect anyone - it has no economic, social, racial or national barriers.
There is no one cause for Alzheimer's disease. AD may be sporadic or passed through the genetic make-up. The
disease causes gradual death of brain tissue due to biochemical problems inside individual brain cells. The
symptoms are progressive, but there is great variation in the rate of change from one person to another. Although
in the early stages of Alzheimer's the victim may appear completely healthy, the damage is slowly destroying the
brain cells. The hidden process damages the brain in several ways:

  • Patches of brain cells degenerate (neuritic plaques)
  • Nerve endings that transmit messages become tangled (neurofibrillary tangles)
  • There is a reduction in acetylcholine, an important brain chemical (neurotransmitter)
  • Spaces in the brain (ventricles become larger and filled with granular fluid)
  • The size and shape of the brain alters - the cortex appears to shrink and decay

Understandably, as the brain continues to degenerate, there is a comparable loss in mental functioning. Since the
brain controls all of our bodily functions, an Alzheimer victim in the later stages will have difficulty walking, talking,
swallowing and controlling bladder and bowel functions. They become quite frail and prone to infections such as
pneumonia. Dementia vs. Normal Aging as a person grows older, he/ she worries that forgetting the phone number
of a best friend must mean he/ she is becoming demented or getting Alzheimer's disease. Forgetfulness due to
aging or increased stress is not normal aging and is not dementia. "Dementia" is an encompassing term for
numerous forms of memory loss. There are many types of dementia such as Alzheimer's disease, Multi-Infarct
dementia or Parkinson's disease. When a person has dementia, he or she will lose the ability to think, reason and
remember and will inevitable need assistance with everyday activities such as dressing and bathing. Changes in
personality, mood are also symptoms of dementia. Many dementias are treatable and reversible. Alzheimer's
disease is the most common form of untreatable, irreversible dementia. Alzheimer's Disease - Stages of
Progression Alzheimer's Disease can be characterized as having early, middle, and late stages through which the
patient gradually progresses, but not at a predictable rate. The range of the course of the disease is 2-25 years.
NOTE: Stages very often overlap. Everyone progresses through these stages differently.

First Stage: This is a very subtle stage usually not identified by either the impaired person or the family as the
beginning signs of the disease. Subtle changes in memory and language along with some confusion occur at this
time. The family usually denies or excuses the performance deficiencies at this stage.

  • Forgetfulness/memory loss
  • Impaired judgment
  • Trouble with routines
  • Lessening of initiative
  • Disorientation of time and places
  • Depression
  • Fearfulness
  • Personality change
  • Apraxia (forgetting how to use tools and equipment)
  • Anomia (forgetting the right word or name of a person)

Second Stage: As Stage 1 moves onto Stage 2, there is usually a particular significant event which forces the
family (and impaired person) to consider that something is really wrong. At this time, they usually go to a doctor to
diagnose the problem.

  • Poor short-term memory
  • Wandering (searching for home)
  • Language difficulties
  • Increased disorientation
  • Social withdrawal
  • More spontaneity, fewer inhibitions
  • Agitation and restlessness, fidgeting, pacing
  • Developing inability to attach meaning to sensory perceptions: (taste, touch, smell, sight, hearing)
  • Inability to think abstractly
  • Severe sleep disturbances and/ or sleepiness
  • Convulsive seizures may develop
  • Repetitive actions and speech
  • Hallucinations
  • Delusions

Third (Final Stage): This stage is the terminal stage and may last for months or years. The individual will
eventually need total personal care. They may no longer be able to speak or recognize their closest relatives.

  • Little or no memory
  • Inability to recognize themselves in a mirror
  • No recognition of family or friends
  • Great difficulty communicating
  • Difficulty with coordinated movements
  • Becoming emaciated in spite of adequate diet
  • Complete loss of control of all body functions
  • Increased frailty
  • Complete dependence



  • Suspiciousness: accusing others of stealing their belongings
  • People are" out to get them"
  • Fear that caregiver is going to abandon (results in AD person never leaving caregiver's side)
  • Current living space is not "home"
  • Hallucinations
  • Seeing or hearing people who are not present
  • Repetitive actions or questions
  • They forget they asked the question
  • Repetitive action such as wringing a towel
  • Wandering
  • Pacing
  • Sundowning: trying to get "home"
  • Generally feeling uncomfortable or restless
  • Increased agitation at night
  • Losing things/Hiding things
  • Simply do not remember where items are
  • Might hide things so that people don't" steal" them
  • Inappropriate sexual behavior
  • Person with AD loses social graces and is only doing what feels good

Agnosia: inability to recognize common people or objects

-A wife of forty years will become a stranger to the person with AD, he might even think she is the hired help
Might not recognize a spatula or the purpose of the spatula and/ or cannot verbalize the name or purpose of the

Apraxia: loss of ability to perform purposeful motor movements
Cannot tie a shoe or manipulate buttons on a shirt
Catastrophic reactions

-(Causes) AD person often becomes excessively upset and can experience rapidly changing moods. The person
becomes overwhelmed due to factors such as too much noise, too many people around, unfamiliar environment,
routine change, being asked to many questions, being approached from behind.
(Reactions) AD person may become angry, agitated, weepy, stubborn or physically violent. It is best to attempt to
avoid catastrophic reactions rather than dwell on how to handle them.


One of the most difficult challenges for caregivers is how to handle some of the disturbing behaviors that
Alzheimer's can cause. Symptoms such as delusion, hallucinations, angry outbursts, suspiciousness, failure to
recognize familiar people and places are often the most upsetting behaviors for families. The following points may
help in responding to disturbing symptoms. First, try to understand if there is a precipitating factor causing the
behavior. Were there household changes, too much noise or
activity, was the daily routine upset? Time of day can also affect behavior (Sundowning). Being aware of these
factors can help to better plan activities or anticipate problems.

1. Keep tasks, directions and routine Simple without being condescending
2. Always give the person plenty of time to respond
3. Attempt to remain calm and remind yourself that the behavior is due to the disease
4. Avoid arguing
5. Write down the answers to frequently asked questions, then remind them to look at the message
6. Reduce environmental noise: television, radio, too many people talking
7. Use distraction when unacceptable behavior starts: bring them into a different room, start talking about childhood
or another favorite topic, show them magazines, ask them to help you do something like dusting or sweeping
8. Do not overreact or scold for problem behavior: redirect or distract
9. Be reassuring with touch, eye contact and tone of voice
10. Find the familiar: old pipe, favorite chair, family pictures
11. Avoid denying hallucinations: try non-committal comments like, "You spoke with your mother, I miss my mother
12. Be sure to inform physician of hallucinations, no matter how tame
13. Restless behavior or pacing is usually unavoidable, however you can make the environment safe by installing
locks that are above reach, remove unnecessary obstacles, make sure the person is wearing some kind of
