Gerontology aspects
Introduction about aging
The beginning :
Aging begins the day

we are born
No single measure of how "old" a person is
Aging is highly individualized
Aging proceeds at different rates in different people, and within different systems of the body
The causes of aging
Many theories to include:
Hereditary Factors
Loss of cellular mass and ability of cells to divide and replicate
Accumulation of waste materials that clog cells and cause them to die
Changes in structure of connective tissue
When Does Aging Begin?!
Why Do People Age?!

Comparison between chronological ,biological and functional age

Слайд 9

Aging
The ageing process
It is a gradual accumulation of irreversible

functional losses which involves not only physiological changes but also social and psychological one.
Aging person
There many differences between old and young people .in only some cases are these changes due to true ageing, ie ,, due to changes in the characteristics compared with when the person was young.

Слайд 10

Comparison between changes due to ageing and not due to ageing

Слайд 11

Theories of ageing
Theories of Aging:
Oxidative damage
Reactive oxygen damage

key molecules including DNA and so impairment in metabolism and cell death.
Abnormal control of cell mitosis
For most cell line the number of times that cell division can occur is limited ,but in other cells , division may continue uncontrolled resulting in hyperplasia and pathologies as diverse as atherosclerosis and prostatic hyperplasia.

Слайд 12

Theories of ageing
Protein modification
Complex glycosylated molecules are the final

result of multiple sugar-protein interactions ,resulting in a structurally and functionally abnormal protein molecule
Wear and tear
Physical damage play apart in ageing of some structures especially skin ,bone and teeth .
Ageing and evolution

Слайд 13

Gerontology
Gerontology
It is the study of aging persons and the

process of aging.
It refers to the study of all aspects of the aging process, including economic, social, clinical, and factors, and their effects on the older adult and on society.
Aspects of gerontology

Слайд 14

Слайд 15

Geriatrics
Geriatrics
It is the medical specialty that deals with the

physiology of aging and with the diagnosis and treatment of diseases affecting the aged.
Geriatrics focuses on abnormal conditions and the treatment of those conditions .
Geriatric nursing
It is the application of the nursing process through the assessment of nursing needs of the older people, planning and implementing nursing care to meet these needs and evaluating the effectiveness of such care to achieve and maintain a level of wellness .

Слайд 16

Demographics
Life Expectancy: the average age of death for members of

the population.
lifespan : maximum possible attainable age , it is thought to be around 120 years , it determined by human biology and has not changed .

Слайд 17

Characteristics of healthy older adults
The vast majorities of elderly ,even with

chronic disease or other disabilities are living outside institutions and are relatively independent .
No one knows conclusively all of the variables that influence healthy aging but it is known that a lifetime of healthy habits and circumstances ,a strong social support system , and a positive emotional outlook.

Слайд 18

Factors affecting health and wellness
Wellness is influenced by many factors

including:
Personality traits
Life experiences
current physical health
Current social support
Personal health behaviors; smoking, obesity….
Their ability to function is a key indicator of health and wellness and is an important factor in understanding healthy aging.
Good health in the elderly means maintaining the maximum possible degree of physical, mental, and social vigor

Слайд 19

Social impact of ageing population
Financing pensions and health services

private pension investment
Healthcare and disability services, the prevalence and degree of disability increases with age.
Families are more likely to be supporting older members
Retired people comprise a growing market and companies/industries that accommodate the needs/wishes of older people will flourish
• Transport, housing, and infrastructure must be built or adapted
• Political power of older people (the "grey lobby‘ in America) will grow
