Memory and Aging:What Everyone Should Know Brent P. Forester MD, MSc Director, Mood Disorders Division, Geriatric Psychiatry Research Program McLean Hospital Assistant Professor of Psychiatry, Harvard Medical School
Outline • Cognition and Normal Aging: Background • When Memory Loss becomes Problematic: Mild Cognitive Impairment (MCI) and Alzheimer’s Dementia 3. Healthy Brain Aging Tips 4. Unique Role of McLean Hospital in addressing questions of the aging brain
The Graying of America WE ARE HERE
Successful Aging • 94 year old woman, widowed • Living at a continuing care retirement community • History of depression • Now with mild memory complaints • PhD in psychology • Trying to get her dissertation published on Sigmund Freud’s introduction to America
Risk Factors for Memory Loss • Age • Obesity • Sedentary Lifestyle • Hypertension • Hyperlipidemia • Diabetes • Alcohol and other Substance Abuse • Depression, Stress
Mechanisms For Memory Loss • Inflammation • Heart Disease • Genetics
Treatable Causes of Cognitive Decline • Vitamin B12 or folate deficiency • Underactive thyroid • Unstable medical problems: diabetes, heart failure • Fluid accumulation in the brain • Medication side effects: Tylenol PM • Excessive alcohol consumption
Memory Changes with Middle Age: 35-55 • Brain becomes more efficient at processing information • Misplace keys and glasses BUT… • Improved managerial skills, seeing big picture, figure out novel ways to solve complex problems Small and Vorgan. The Alzheimer’s Prevention Program. 2012.
Memory Changes with Aging: Beyond age 55 • Forgetfulness • Slower processing of information • Learning and recall is slowed down
Mild Cognitive Impairment (MCI) • Memory decline on at least one standard memory test • Functioning is normal • 10 million in US over the age of 65 • 10-15% per year convert to Alzheimer’s Disease
Alzheimer’s Disease • Alzheimer’s disease (AD) affects about 5.4 million Americans¹ • Most are aged 65 years and older, with prevalence reaching nearly 50% at age 85 and older1 • New AD diagnosis every 70 seconds • AD patients typically live about 7 to 10 years after diagnosis2,3,4 1.

Risk for Alzheimer’s Disease • Age • Family history • Genetics – APOE 4 • Down’s Syndrome • Depression • Cerebrovascular factors – diabetes, high cholesterol, hypertension
Alzheimer’s Disease: Redefining the Criteria • Pre-Clinical Alzheimer’s Disease • MCI of Alzheimer’s Disease • Dementia due to Alzheimer’s Disease
Steps to Improve Memory as We Age • Memory Training • Nutrition • Exercise
Memory Training and Brain Fitness • Practice memory techniques • Games, puzzles, new approaches to daily activities • Education
Look, Snap, Connect • Look – actively observe/pay attention to what you want to learn • Snap – create a mental snapshot or picture of the information (real or imagined) • Connect – bring two mental snaps together Small and Vorgan 2012
The Mediterranean Diet Associated with improved cardiovascular health, reduced risk of dementia and depression (30%)
Healthy Brain Diet • Limit caloric intake, avoid processed foods • Moderate caffeine and alcohol intake • Omega 3 fatty acids – reduce risk for heart disease, stroke and cognitive decline • Antioxidants – limiting damage from free radicals • Vitamin E – 400-800 IU/day • Vitamin C – 500-1000 mg/day
Exercise • Exercise at mid-life reduces subsequent risk of dementia1 • Increases brain cell growth in animals2 • Increases brain blood flow in humans3 1. Andel, 2008; 2. Gage 2002; 3. Rolland 2008
Tips for Successful Aging • Healthy brain and heart diet • Minimize stress • Mental and physical aerobics • Plan for retirement • Maintain social relationships • Attitude is KEY • Assess and treat memory problems early on
Geriatric Psychiatry Research at McLean Hospital • Well situated to study common late life psychiatric disorders (depression, anxiety, dementia) • Large clinical population: inpatient, outpatient, community • Collaboration among clinical programs, McLean Imaging Center and the Mailman Research Center • Use advanced technologies to explore behavioral symptoms and syndromes that reflect the effects of aging and physical illness on brain function
