TRANSCRIPT
Adulthood 127-132• All physical
abilities essentially peak by our mid twenties. Then it all goes downhill.
Physical Milestones
• Menopause: the natural ending of a woman’s ability to reproduce
• Men do not experience anything like menopause.
Alzheimer’s Disease
• A progressive and irreversible brain disorder characterized by gradual deterioration of memory, language and physical functioning.
• Runs its course in 5 to 20 years.• Deterioration of neurons that produce the
neurotransmitter….Acetylcholine
Estrogen supplements may stop the onset of Alzheimer’s Disease.
Cognitive Changes
• We tend to remember events from our teens and twenties.
• Difference between recognition and recall. Recognition remains stable. Recall declines with old age.
Do old people get stupid?
• Cross-sectional studies show decline.• Longitudinal Studies show consistency.
What is the difference?
Cross-sectional studies: study with people of different ages studied at the same time.
Longitudinal Studies: same people studied and retested over a period of time.
