Dementia
As you learned in Week 1, normal aging is not characterized by significant loss in physical or cognitive functioning. Although there are gradual changes during the aging process, people are usually able to cope with and adapt to those changes, because the changes happen slowly. When significant changes do occur, it is often a result of a physical or mental illness. The onset of dementia, for example, represents a significant change due to physical or mental illness.
Dementia is defined as a significant change in general cognitive functioning such as memory, reasoning, language, or thinking skills. Significant implies that the impairment is great enough to disrupt a person’s everyday life. Dementia is caused by a host of different disorders and conditions.
Some of the conditions that cause dementia are reversible, such as nutritional deficits or depression. Some conditions are associated with infectious diseases such as HIV and Creutzfeldt-Jakob disease. Disorders associated with genetic or inherited traits such as Huntington’s disease will cause dementia. Physical damage to the brain due to stroke or vascular disease has also caused dementia. Other conditions have unknown (or unidentified) causes such as Lewy Body, Parkinson’s, and Alzheimer’s disease. Alzheimer’s disease is one of the most common disorders that cause dementia.
Diseases like Alzheimer’s progress over a number of years. Such diseases become a significant life stressor not only for the individual with the disease, but for family members as well. Typically, the primary care provider for a person with Alzheimer’s disease is a family member. The majority of individuals with Alzheimer’s disease remain in their own home, or the home of a family member, for the duration of the disease.

Stress and Coping
The two scenarios below describe events in the lives of two men, Jorge and Bill. Both are 75 years old
and each has gone through a traumatic event.
Scenario 1
Jorge is now living alone. His wife of forty-nine
years, Luisa, left him for another man. To make
matters worse, the other man was Jorge’s best
friend, Ramón. Jorge has been alone for a week
and he still does not understand why his wife
left.
Scenario 2
Bill was reading the newspaper. He read about
an estate sale on Saturday. Bill yelled out to his
wife, Mary, to see if she wanted to go. It has
been a year since Mary passed away, but
sometimes Bill still forgets that she is no longer
with him.
Of Jorge and Bill, which one seems to be going through what is considered a normative life event?
Which one is going through a non-normative life event? Normative life events are those life experiences
that are considered common for a particular age group. For Bill, being a widower at 75 is a normative
life event. Although the loss of his wife may be tragic, it is an event that many older adults go through.
Furthermore, the loss of a spouse is much more common for people in their seventies than for people in
their thirties.
On the other hand, Jorge seems to be going through a non-normative life event. Older adults do get
divorced, but it is less common, especially for couples that have been married as long as Jorge and his
wife were married, when older adults divorce, infidelity is rarely the cause.
Coping Strategies
The question becomes, would a non-normative event such as divorce be more difficult to cope with than
the death of a spouse? For an older adult, the death of a spouse is a normative event; divorce is not.
Both are significant life stressors. However, even though a couple has divorced, that doesn’t necessarily
mean the former spouses wouldn’t be able to maintain contact with each other.
Individual coping strategies are derived from a person’s sense of self-esteem and self-efficacy. Self-
esteem is an individual’s evaluation of his or her own self-worth. Self-efficacy is an individual’s belief in
his or her ability to accomplish personal tasks and goals.
As a person ages, that person develops or grows into certain roles, whether in a career or in family life.
As you have already learned, those social roles help to define a person. Someone who spent thirty years
as a teacher may have difficulty adapting to a new role after retirement. A person’s self-esteem is also
influenced by social roles within the context of family, and, to a lesser extent, with friends and social
acquaintances.
As children grow and leave home to raise their own families, older adults may become less central in the
family dynamics. Membership in social organizations and friendships also changes over time, especially
for older adults. Close friends pass away. Individual roles within organizations change as activity levels
change. All of these issues can have an effect on an older adult’s self-esteem and self-efficacy. How
might older adults cope with such change in their life?
Change is gradual. For the most part, the changes described in this week’s lectures are anticipated,
normative life events and experiences. An individual may have had many years to prepare for such
changes. Also, the transition is not without support, as roles change, new roles can develop and emerge.
Older adults may not be active in parenting their grown children, but that doesn’t mean that their
parenting skills are no longer needed. It is very common for grandparents to take an active role in the
lives of their grandchildren.
In recent years healthy aging and living has become a common idea for older adults. Many adults have
turned to a more active and productive lifestyle. The old stereotype of older adults retiring to the
rocking chair on the porch is a thing of the past. An active and healthy living lifestyle provides strong
coping mechanisms even when facing chronic illness (Schneller & Vandsbuger, 2008).

Causes of Dementia
Alzheimer’s Disease
There are two main types of Alzheimer’s disease: early onset and late onset. Individuals who are diagnosed with the disease before the age of 65 are classified as early onset. Those who are diagnosed after the age of 65 are classified as late onset. The cause of the disease is not known, but there are risk known risk factors including age, lifestyle, and heredity factors. In recent years, researchers have linked genetic factors as well. The stages of the disease are marked by changes in overall cognitive and physical functioning. In the early stages, memory loss and changes in executive functioning are apparent. In the late stages, cognitive functioning diminishes to the point where the individual loses the ability to engage in basic activities of daily living (bathing, grooming, dressing, and dining) and the capacity for verbal expression. Toward the end stage, the individual will also lose the ability to ambulate and move purposefully.
Lewy Body Lewy Body Dementia (LBD) is a disease that manifests in ways that are similar to other types of diseases that cause dementia. Patients with LBD exhibit the cognitive changes related to Alzheimer’s disease and the physical changes related to Parkinson’s disease. The change in functioning is due to the presence of Lewy Bodies, protein structures that develop in different parts of the brain. The same types of structures have been found in individuals diagnosed with Parkinon’s. Individuals with Lewy Body disease also have plaques and tangles, which are hallmarks of Alzheimer’s disease. Some have speculated that Lewy Body is a variant of Alzheimer’s or is another type of Parkinson’s. The disease also produces hallucinations and delusional problems for some individuals.
Vascular Dementia
Vascular dementia results from brain tissue damage. Such damage is caused when blood flow to the brain is interrupted. The interruption may occur when a blood clot blocks the flow of blood in the brain or when a blood vessel breaks. The damage can range from minor to major physical and mental changes. The tissue damage can cause memory loss, personality change, loss of movement, as well as overall functional limitations, including the impairment of ADLs. Overall cognitive and intellectual loss can also occur, depending on the extent of the damage.

Other Causes
Other diseases that cause dementia include:
• Creutzfeldt-Jacob disease • Huntington's chorea • Infectious diseases, such as encephalitis, HIV, or syphilis • Multiple sclerosis • Parkinson’s disease • Pick’s disease
Reversible Dementias
Some diseases that cause dementia can be treated and the dementia reversed. These diseases include:
• Brain tumors • Chronic alcohol abuse • Drug use and abuse • Exposure to toxins or toxic substances • Hydrocephalus • Hypoxia • Metabolic conditions and disorders • Nutritional deficiencies
