predictors for longevity
heriditary- 50% of fathers to people over 80 also lived past 80
other predictors- regular checkup, minimal caffeine and alcohol, work gratification and perceived sense of self as being useful, eating healthy, exercise
changes in causes of death -CVA, MI
60% decline in mortality fromm CVA, 30% in coronary
leading causes of death among older people
heart disease, cancer, stroke
also accidents are prevalent- e.g. falls- most commonly resulting from hypotension or arrythimia
M:F ratio with age(per 100 females)
55-64: 92
65-74- 83
75-84- 67
85< - 46
alcohol , salt, statins and longevity
1 oz =30 ml of alcohol a day reduce HDL and correlate with longevity
salt less than 3 gr- reduce hypertension
statins reduce CV disease in diet and exercise resistant hyperlipidemia
aging changes- neurons
degenaeration mainly in superior temoral ,precentral and inferior temporal gyri.
no loss in brainstem nuclei
aging- cellular changes
increased collagen and elastin
altered receptor sites and sensitivity
deacreased anabolism and catabolism of cellular transmitter substances
immune changes in aging
increased autoimmune,
leukocytes unchanged but reduced T lymphocytes and their response
increased ESR

difficult to shift attention
encoding and simple recall diminish
recognition remains intact
neurotransmitters -aging
decreased NE and increased MAO and serotonin
brain changes - aging
17% decrease of brain weight by 80
wide sulci, smaller convolutions, gyral atrophy
enlarged ventricle
increased transport in BBB
decreased cerebral blood flow and oxygenation
cardiovascular- aging
increased in size and weight- lipofuscin
decreased valvulaar elasticity
cardiac output maintained in absence of coronary heart disease
