Facts Predominantly a disease of the elderly, but affects young, too Prevalance for Alzheimer s >65 y.o., 5% >85 y.o., 50% 2 nd most feared disease among the elderly 5 million affected in U.S. Estimate 20 million by 2050
Myths It is irreversible It is untreatable There are no effective means to prevent it
Dementia Loss of memory or other cognitive functions Can be caused by numerous untreatable, but also treatable diseases Sometimes mistaken for other symptoms Normal aging Benign forgetfulness Aprosexia
10 Warning Signs 1. Memory loss 2. Difficulty performing familiar tasks 3. Misusing words 4. Confusion about time 5. Confusion about place 6. Problems with judgement & reasoning 7. Difficulty with abstract concepts 8. Personality change 9. Mood changes 10. Loss of initiative
Causes Most common untreatable cause is: Neurodegenerative disease such as Alzheimers Common treatable causes: stroke pseudo-dementia (depression) medications metabolic disorders infections

Diagnosis: Step 2 Routine laboratory tests Electrolytes, blood sugar, liver, & kidney Blood count Thyroid test Vitamin B 12 level Urinalysis
Diagnosis: Step 3 Brain scan (routine) CT (or MRI)
Step 4: Special Evaluations (not routinely performed) Neurology Consult Psychiatry Consult Neuropsychometric testing Spinal Tap EEG (electroencephalogram) Cerebral arteriogram
Step 5: Pay the Bill
Learning Pearl Though most UNTREATABLE causes of dementia can only be definitely diagnosed by AUTOPSY OR BRAIN BIOPSY, reasonable certainty can be made by a detailed history, physical exam, & laboratory tests or x-rays that EXCLUDE TREATABLE causes
Treatment Specific treatment for reversible causes: B 12, antibiotics, modify medications, prevent stroke, treat depression, thyroid supplement, remove/treat brain tumor, shunt for hydrocephalous, etc.
Treatment 1. Cures 2. Delays or reverse the damage or stop progression of the disease 3. Symptomatic 4. Provide Hope Replace neurotransmitters Decrease inflammation Decrease toxic substances Vaccine
Effect of physical activity on cognitive function in older adults at risk for Alzheimer Disease Conclusion A 6 month program of physical activity provided a modest improvement in cognition over an 18 month follow-up period Journal of the American Medical Association. Sept 3, 2008, vol 300(9), pg 1027
Healthy diet, exercise, and socialization may protect against dementia. Healthy diet to avoid obesity may decrease risk for dementia Physically active adults have lower risk for Alzheimer s disease than inactive adults Social disengagement may be a risk factor for cognitive impairment among older persons (Neurology Reviews, Aug 2008, pg 37)
