  1. Chapter 24 Cognitive Development in Late Adulthood Michael Hoerger

  2. Brain Slowdown • Cognitive tasks are slower with age • Breakdown of myelin • Reduced production of neurotransmitters • Slower blood flow • Not usually due to neuron death • Healthy diet and education may be protective factors

  3. Dementia • Definition: cognitive decline, for judgment, memory, and problem solving • Over 70 causes; we’ll focus on two 1) Strokes can cause “vascular dementia” or “multiple infarct dementia” • Infarcts (blocked blood vessels) prevent oxygen from reaching the brain • Ministrokes are silent and common • Lack of exercise, poor diet, and smoking increase risk

  4. 2) Alzheimer’s Disease: most common dementia, characterized by plaques and tangles • Autopsy findings • Strokes = more decline • Odds increase with age, 20% over 85 • Genetics factors can increase or decrease risk • Risk reducers: healthy diet (fruits and vegetables), intellectual stimulation, physical exercise, no smoking
