Gerontologists
Specialists who study ageing
We can no longer define old age my chronological years alone: we also must take into account peoples physical and psychological well-being, they’re functional ages. Explain the three groups of people according to functional ages
The young old are healthy and active. The old old have some health problems and difficulties with daily activities. The oldest old are frail and need to care
Ageism
Prejudice and discrimination directed at older people
Primary aging
Also known as senescence. Primary ageing is ageing that involves universal an irreversible changes that due to genetic programming occur as people get older
Secondary ageing
Changes in physical and cognitive functioning that are due to illness health habits and other individual differences but are not due to increased agent self and are not inevitable
Peripheral slowing hypothesis
The theory that suggests that overall processing speed to clients in the peripheral nervous system with increasing age
Generalized slowing hypothesis
The theory that processing in all parts of the nervous system including the brain is less efficient as we age
Cataracts
Cloudy or OPK areas on the lens of the eye that interfere with the passage of light
Intraocular lens implants
When a plastic lenses permanently placed in the eye
Glaucoma
Glaucoma occurs when pressure in the flute of the eye increases either because the fluid cannot drain properly or because too much fluid is
Macular degeneration
Macular degeneration leads to a gradual deterioration of the centre of the retina leaving only proof feel vision
Age related macular did generation effects of the_______
Macula, a yellowish area near the right now which visual perception is most acute
Arthritis
Inflammation of one or more joints
Hypertension
High blood pressure. Around 1/3 of older adults have it
Dementia
The most common mental disorder of older adults, they cover several diseases Each of which includes serious memory loss and companied by the clients and other mental functioning
Alzheimer’s disease
A progressive brain disorder that produces memory loss and confusion
Beta amyloid precursor protein
When this protein goes awry Alzheimer’s disease occurs
Genetic programming theories of ageing
Series that suggest that her body is DNA contains a built in time limit for the reproduction of human cells
Wear and tear theories Of ageing
The theory that the mechanical functions of the body simply where out with age
Life expectancy
The average age of death for members of a population
Telomere therapy
Hello music are tiny areas at the tip of chromosomes that grow shorter each time a cell divides and eventually disappear ending cell replication. Some scientists believe that if telomeres could be lengthened Adrian could be slowed. Researchers are now looking for genes that control the production of telomerase an enzyme that seems to regulate the length of telomeres
Unlocking longevity jeans
Certain genes control the body’s ability to cope with environmental challenges and physical adversity. If hardest those dreams may provide a way to increase the lifespan. One particular Lee promising family of genes is sortions, which might regulate and promote longer life
Reducing free radicals through antioxidant drugs
Free radicals – unstable molecules that dripped through the body – damage other sales and leave the evening. Antioxidant drugs that can reduce the number of free radicals might eventually be perfect. Furthermore it might be possible to insert into human cell dreams that produce enzymes that act as antioxidants. In the meantime nutritionists urge a diet rich in antioxidants vitamins which are found in fruits and vegetables
Restricting calories
For at least the last decade researchers have known that laboratory rats were fed and extremely low calorie diet providing 30 to 50% of their normal intake often live 30% longer than better for rats, providing they get all the vitamins and minerals they need. The reason appears to be that they produce if you were free radicals. Researchers hope to develop drugs that maybe the effects of calorie restriction without forcing people to feel hungry all the time
