Alzheimer's Disease
From Anvita Health Wiki
Contents |
More Specific Terms
- early-onset Alzheimer's disease
- familial Alzheimer's disease (FAD)
- Lewy body variant of Alzheimer's disease (AD)
Etiology
Epidemiology
- 4 million persons in USA affected
- 4th leading cause of death; 46,000 deaths/year
- 35% of dementia pure AD; 15% mixed AD/ vascular dementia
- 5% age 65-74; 15-25% age 75-84; 35-50% > 85 years of age
- 70% of women & 17% of men > age 90 ( ADAMS study, 2006)
- prevalence of neuropathologically-defined AD may be substantially higher than clinically-defined AD (2x) [8]
Pathology
Genetics
Clinical-manifestations
Laboratory
- see laboratory evaluation of Alzheimer's disease
- also see laboratory evaluation of dementia
Diagnostic-procedures
- electroencephalogram ( EEG): seizure disorder
- small bowel biopsy to rule out intestinal lipodystrophy ( Whipple's disease)
- brain biopsy: only definitive test
Radiology
Complications
Differential-diagnosis
Management
- see guidelines for AD management
- pharmaceutical agents (see pharmaceuticals for treatment of AD)
- associated behavioral syndromes (see pharmaceuticals for treatment of AD)
- bright light +/- melatonin may reduce cognitive decline & improve physical function [16]
- adequate nutrition
- regular exercise
- prognosis:
- associated with shortened survival [13]
- mean life span 9.6 +/- 3.5 years after diagnosis [15]
- prognosis dependent upon several factors
- patient education
- caregiver support
- financial planning
- home care needs
- advanced directives
- also see guidelines for Alzheimer's disease (AD) management
- Alzheimer's disease is a reportable disease & must be reported to the health department
- Follow-up:
- every 4-6 months
- assess & document cognitive decline & behavioral changes
- health maintenance
- assess caregiver burden
