Studying Aging Connotations: A negative psychological shift. Western cultural views are different from others GERONTOLOGY: The study of aging. GERONTOLOGIST: One who studies aging.
Retire Younger Old People Should Retire So That Younger People Can Work?
Why study the effects of aging? (5 reasons): biology of aging (genetic and environmental factors associated with aging) shift in survival and life expectancy has itself driven the inquiry about the social implications medical science documents the diseases of old age and attempts to moderate their effects

The Changing Face of the Nation Baby Boomers approaching retirement. Elderly are living longer - combination of modern medicine and lifestyle related factors = age 115 years
Changing Face of the Nation higher quality of life - therefore older people are a major social, political and economic factor in society. Changing demographics also reflected in fact that not as many children are being born in first world countries.

THEORIES ON AGING Biological: – “ It’s Not the Years.., It’s the Mileage”the wear and tear theory – “ It’s Not the Years.., It’s the Mileage” the human body simply wears out the human body simply wears out some activities may predispose this condition (running)some activities may predispose this condition (running)
THEORIES ON AGING the cellular theory – limited number of cells / capacity to reproduce / once exhausted body begins to deteriorate / varies from individual to individual the autoimmune theory – declining immune system / loses control attacking body
THEORIES ON AGING the genetic mutation theory – the older you are the more mutant cells develop/ function differently than intended / dysfunction of body organs + systems
Physical Changes The Skin: (30’s)thinner + loses elasticity /(40’s) lines on the face / (50’s) crow’s feet /(60’s) loses colour + sags / (70’s) age spots etc. Bones and Joints: constantly changing accumulating and losing minerals (modeling)constantly changing accumulating and losing minerals (modeling) 30’ and 40’s – net loss of minerals – could lead to osteoporosis30’ and 40’s – net loss of minerals – could lead to osteoporosis
Physical Changes OSTEOPOROSIS: loss of bone material / bone mass post-menopausal women fractures common very debilitating risk factors: calcium, lack of exercise, lack of estrogen therapy post- menopause
Physical Changes The Head: features of the head enlarge ( nose, ears, head - skull thickens) Brain shrinks The Urinary Tract: urinary incontinence individual treatable - drug therapy
Physical Changes Heart and Lungs: Resting Heart Rate stays about the same throughout life stroke volume decreases heart muscle deterioration Vital Capacity decreases (max. inhalation + exhalation) exercise slows these changes
Eyesight: 30 years of age – lens harden 40 years of age – lens: yellow and looses transparency Cataracts – (clouding of the lens) / focus on retina / blurred vision / blindness possible glaucoma – ( increased pressure within the eyeball) hardening of the eyeball, impaired vision, eventual blindness

Getting Around and body Comfort Mobility: 50% of older Canadians Report some disability related to mobility or agility Body Comfort: loss of body fat / thinning of epithelium / diminished glandular function body temperature hypothermia / heat stroke / heat exhaustion
Mental Changes:Intelligence: unchanged - except for illness continue to learn and develop (time?) compensate with practical knowledgeMemory: short-term can be memory - affected long-term unchanged
Coping with Change Flexibility vs. Rigidity: LIFE = diverse joys, sorrows, and obstacles –developed coping methodsDepression: most adults continue to lead healthy, fulfilling lives however, depression is the most common
Alzheimer’s Disease and other Dementias Dementias – progressive brain impairments that interfere with memory and intellectual functioning
ALZHEIMER'S DISEASE The disease most dreaded by the elderly is dementia; loss of mental functions in an alert individual, characterized by group of symptoms : memory loss loss of language functions inability to think abstractly inability to care for oneself personality change emotional instability loss of sense of time
ALZHEIMER'S DISEASE three quarters (75%) dementia’s caused by Alzheimer's disease - chronic, degenerative dementing illness / cause unknown no known cure to stop the progression 6% of people over 65 years have Alzheimer's disease Alzheimer's disease 4th leading cause of death - older adults < seventy conditions can cause dementia
Types of Dementia: Degenerative = Alzheimer's, Parkinson's, Huntington's. Vascular dementia: cerebral embolisms, blood clots, and infarctions. Traumatic dementia: head injuries. Lesions: tumors, hematomas, and cancers. Toxic dementia: alcohol, poisons. Others: epilepsy, post-traumatic stress disorders, and heat stroke.
THEORIES OF AGING: Brain size & longevity Biological clock determines how long we live. Disposable soma: Allocation of resources - optimal is as little as possible to body repair, and more to other functions. Wear and tear: Accumulated damage leads to breakdown - like a machine!
Genes and Aging Genetic theories: Loss of genetic info. over time = loss of protein to rebuild. Immunological: Breakdown of immune system. Others: Error accumulation, cell loss, nutritive, environment, and brain chemistry.
