Middle Adulthood Erikson Age
40-65
Young Adulthood Erikson Age
19-40
Advanced Maternal Age
> 35 years
What is the “Positivity Effect”
pay more attention and recall positive stimuli
less amygdala reactivity with negative stimuli
-how perception changes with age
Memory and Information Process Changes
slower processing speed, trouble filtering distracting stimuli
slower processing (due to diabetes, chronic pain) with increased problem solving
perceived memory loss (no difference)
DIetary Prevention of Cognitive Decline
Caffeine: moderate (2-3 cups/day) lowers risks of dementia
Alcohol: WHO: no level safe
Mediterranean Diet: fruit, veg, grains, low red meat
Presbyopia
Loss of visual acuity from:
-thickening of lens (can’t see up close)
-build up of debris and deterioration of light receptors in retina –> age-related macular degeneration
Other Vision Changes
Difficulty adjusting to changes in light
-pupil does not dilate or contrict
-difficulty seeing at night
Presbycusis
nerve and inner ear deteriorate
difficulty with high frequency sound waves (microwave beep)
Common Causes of Hearing Changes with Age
can be exacerbated by smoking, HBP, and diabetes
or due to chronic noise exposure (affects 25% of US adults)
Skin Sensitivity Changes
loss of elasticity, sensitive to hot/cold
Propioceptive Changes
more prone to lose balance, falls, ankle injurys
Sarcopenia
age-related muscle loss
1-2%/year loss in adults 50+
Metabolism Changes
decreased BMR, less energy needed at rest
Skin Changes
loss of elasticity, thickness, water, fat
appears loose
wrinkles, age spots, sagging
increased risk of skin cancer, decreased with sun protecting
Ostepenia
weaking of bones
T-score: -1.0–2.4
weaker than healthy bone
Osteoporosis is characterized by…
T-score lower than -2.5
higher risk for fractures
may cause pain, bone fragility, increased with for deformities
Osteogenesis Imperfecta
inherited disorder of extreme fragile bones
“brittle bone disease”
Osteoporosis
more common in females
risks can be reduced through diet (calcium, vitamin D)
and exercise (strength training, weight bearing) to support balance, metabolism and cognition
Female Hormonal Changes Due to Pregnancy
estrogen and progesterone peak, relaxation of ligaments and joints
Menopause Hormonal Changes
(40-60)
estrogen peaks at 30 then drops
Premenopause
irregular cycles
Perimenopause
irregular cycles
can still get pregnant
“hot flashes”
brain fog, memory
Postmenopause
no cycle for a year
embarrassment, loss of control, anxiety
wisdom, mentor others, new chapter of life
