Development: Ageing Flashcards
What are the 2 types of ageing?
primary - natural decline
secondary - results from disease, disuse or abuse
What is the menopause?
What is it caused by?
What are the primary/secondary symptoms?
Treatment?
- end of reproductive year, -occurs in all women
- caused by decline in oestrogen
- primary = hot flushes, night sweats
- secondary = vaginal dryness, depression, somatic symptoms, fatigue etc.
- treatment = HRT but less so today
Why do we age?
What are the 4 biological theories of ageing?
- Wear and Tear
- Cellular
Type 1 - limited to the number of types a cell can divide
Type 2 - cross-linking proteins in cells interact to produce molecules leading to stiffness
Type 3 - free radicals interact with molecules and cause cellular damage and shut organs down
Type 4 - DNA is unable to replicate itself when cells divide / DNA repair system - Rate of living - born with limited amount of physiological capacity
- programmed cell death - cells are genetically programmed to die
What are the physiological changes that occur when we age?
Brain = cell body and axon changes, plaques
CVS = acculumation of fat deposits, stiffening of artery walls
IRM = rib cage and air passagways become stiffer
Appearance and movement = skin, muscle decline, internal bone mass decline
Senses = transmissiveness
Immune function = changes in immune cells
What are some psychological and cognitive changes that occur with ageing?
- infromation processing
- attention
- physcomotor spped
- mental and psycho-social health concerns
- organic mental disorder
- changing relationships
What is dementia?
What is the pathogenesis?
Relentless progressive cognitive decline - permentant brain damage and incurable
Microscoping changes involving neurones
- neurofibrillary tangles
- neurtic plaques
What are the characteristics of dementia?
- communication difficulties
- spatial and temoral disorientation
- aberrant behaviours
- incontinence
- memory loss
- changes in personality
- depression/paranoia
- diminished ability to self care
- inappropriate sexual behaviours
- wandering
- family burden and stress
