no less powerful or pervasive “All Rivers Run to the Sea” “Memory is a passion no less powerful or pervasive than love.” Elie Wiesel “All Rivers Run to the Sea”
Dementia Prevalence 8% over 65 years + 8% MCI 47% at 85 years
The Economics of Dementia Total Costs = $100 BILLION annually Individual excess lifetime costs = $170,000 Patients in nursing homes with Alzheimer’s disease are more expensive to look after than those not afflicted .
Mild Cognitive Impairment Complaints and objective evidence of memory problems No defects in ADLs Abnormal memory for age Not demented Not depressed (Winblad et al; J Int Med. 2004)
Mild Cognitive Impairment OUTCOMES Poor functional recovery from major event 30% dead within 5 years 30% develop Alzheimer’s disease within 5 years
Mild Cognitive Impairment is NOT BENIGN
Mild Cognitive Impairment WHO PROGRESSES? Small hippocampal volumes Decreased blood flow to posterior cingulate gyrus Increased CSF tau protein and decreased beta- amyloid (1-42)
Families and physicians fail to recognize dementia. 50% of persons with mild to moderate dementia have not been diagnosed
Mini-Mental Status Examination Folstein et al. 1975 Educationally dependent Both false positives and false negatives Minimal testing of visuospatial system

CONCLUSION The SLUMS is an acceptable alternative to the MMSE It also identifies MNCD Copyright belongs to the US Government as it was developed by St Louis GRECC Clinicians CONCLUSION
