Document Summary
Sds 150r - lecture 15 - physical and cognitive development in middle adulthood. Changes in two main components of the brain = white matter volume increases until middle adulthood and declines, while grey matter continues to decline. Volume of cerebrospinal fluid (csf) = increases steadily across lifespan. Brain respond more slowly to cognitive tasks. Less ability to control attention processes by inhibiting brain responses to irrelevant stimuli. Osteoporosis: loss of calcium from bones, reduced bone mass and more brittle and porous bones. Other factors: race, gender, weight (underweight higher risk), timing of climacteric. fam. history, diet, exercise can be prevented by getting enough calcium regular exercise, esp. weight bearing exercise early detection: weight mineral test. Begins at about age 30 for both men and women (but for women = process accelerated by menopause due to decreasing estrogen and progesterone levels in premenopausal) Significantly increased risk of fractures, beginning as early as age 50 for women and much later for men.
