Three types of longevity Average life expectancy is the age at
which half the people born in a particular year will have died. Average life span for women is80.4 and men is 75.4 years
Useful life expectancy is the number of years a person is free from debilitating chronic disease
Maximum life expectancy is the oldest age to which any person lives, currently 120 yrs.

Heredity is a major factor in longevity Environment plays a role through the
effects of disease, lifestyle, and toxins Social class plays a role because
certain conditions are related to lack of access to health care

Programmed Theories – functioning may be part of a master genetic program with a biological clock
Damage or error theories – Wear-and-tear theory suggests that the
body simply wears out Free radicals cause cellular damage,
aging is caused by this damage over the lifetime
Cross linking – some proteins interact randomly with certain body tissues and stiffen these tissues

Cellular theories focus on the buildup of toxic cellular substances and subsequent deterioration Some research indicates that cells have an
absolute limit on the number of times they can divide
Telemeres on ends of chromosomes become shorter with each replication until they are too short and the chromosome becomes unstable and cannot replicate and they are susceptible to prolonged stress

Other Wear and Tear Approaches Free radicals - chemicals produced by
cell division that cause cell damage Cross-linking is an explanation that
suggests that certain proteins interact with body tissue, which results in stiffer tissues. Heart, muscle, and arteries can be affected

Metabolic Theories These theories examine the interaction
between caloric intake and stressProgrammed Cell Death Theories
This approach points to evidence that aging is biologically or genetically programmed
Recent information about human genetics is contributing to these explanations

Changes in the Neurons The fibers in the axon form spiral-
shaped masses called neurofibrillary tangles, which interfere with transmission of signals increased in Alzheimer's Disease and forms of dementia
Damaged or defective neurons collect around a core of protein and form neuritic plaques, which interfere with other, healthy neurons. Large numbers cause dementia.

The speed at which a person can make a specific motor response (psychomotor speed) may slow with advancing age
This finding may be due to taking longer to decide what response to make, especially when faced with an ambiguous situation
These changes make driving with advancing age a controversial issue

Working memory is the information that is being used at the moment, Involves the processes and structures involved in holding information in mind and simultaneously using it to solve a problem, make a decision, perform some function or learn new information.
Working memory typically declines with age A combination of declining working memory
and psychomotor speed may explain decline in cognitive performance in older adults

Explicit memory is the deliberate and conscious remembering of information Episodic memory is memory of
information from a specific time or event Semantic memory is the remembering
of the meaning of words or concepts unrelated to a specific time or event
Implicit memory is unconscious remembering of information learned at an earlier time

Depression is diagnosed based on two changes: Feelings and physical changes present for 2 weeks Feelings of sadness are called dysphoria Physical changes include loss of appetite,
insomnia, and trouble breathing,memory problems
Evaluation of older adults is difficult because some of these changes may be normal
Significant impairment of daily life Other causes must be rules out

Biological and physical causes may include imbalances in neurotransmitters
Loss and internal belief systems may play a role in how people interpret things that happen to them

Depressed people tend to believe that-
They are personally responsible for the bad things that happen to them
Things are unlikely to get betterTheir whole life is in shambles

Medicines that affect the levels of neurotransmitters, such as heterocyclic antidepressants (HCAs), monamine oxidase inhibiters (MAOIs), and selective seratonin reuptake inhibitors (SSRIs), may be used
SSRIs used first because fewer adverse effects, then HCAs and lastly MAOIs which have potentially fatal reactions with some foods – cheddar cheese, wine, chicken liver

Psychotherapy in the forms of behavior (depressed people experience too few rewards or reinforcements from their environment) therapy or cognitive therapy (maladaptive beliefs about oneself are responsible for depression) may be used to learn new behaviors or examine the way patients think about their experiences. Cognitive therapy is the therapy of choice for older adults.

Anxiety disorders involve excessive dread in everyday situations, feelings of severe anxiety for no apparent reason, phobias and obsessive-compulsive thoughts or actions.
Anxiety disorders are more common in older adults, partly due to loss of health, relocation of residence, isolation, loss of independence, and other factors, more common in women.
Anxiety disorders can often be successfully treated with psychotherapy and medications
Psychotherapy is tx of choice for the aged

Dementia is a family of diseases that results in serious behavioral and cognitive impairments. Alzheimer’s disease is one of the more common
Alzheimer’s disease may cause confusion, disability, and dependence
The incidence of Alzheimer’s disease increases with age, 50% for those 85 and older. Women are at greater risk

Confusion and difficulties in communication Changes in personality, inappropriate social
behavior, and decline in hygiene Incontinence, or the loss of bladder or bowel

Diagnosis can only be confirmed by autopsy
Diagnosis is made by microscopic analysis of neurons in the brain
The diagnosis of possible Alzheimer’s disease is based on extensive psychoneurological testing and ruling out other causes for symptoms
Possibly abnormally high levels of the protein amyloid in the blood

The exact cause is not knownPossible explanations have included
a slow-acting virus and aluminum deposits in the brain. These have not be confirmed
Genetic research has shown promising results in identifying genetic markers related to specific genes

Familial,early Alzheimer’s before age 60 – certain genes indicate 100% chance of developing Alzheimer’s
Later onset may be linked to risk genes

Though symptoms can be successfully treated, no cure exists
Galantamine appears to help memory loss but does not reverse the deficits
Thioridazine and haloperidol are used to treat severe psychotic symptoms
Spaced retrieval – remembering new information and increasing the time between retrieval times
Antidepressants may be used to treat the depression that often goes along with the disease
Maintain dignity and optimizing level of functioning
