- Educate patient and family regarding diagnosis
- See specific concerns in Dementia above
- Regular Exercise improves quality of life
- Teri (2003) JAMA 290:2015-22
- Start acetylcholinesterase inhibitor (see below)
- Titrate medication to most effective dose
- Informed consent with patient and family
- Set reasonable expectations
- Medications offer only modest benefit at best in function
- Rate of cognitive decline and outcomes including Nursing Home placement are not affected
- Re-evaluate at 6 month intervals
- Repeat scales performed at baseline (MMSE, ADL, IADL)
- Indicators to continue acetylcholinesterase inhibitor
- Patient improved or stable on current agent
- Indicators to switch to other agent
- Decline in MMSE (>2 points)
- Decline in ADL or IADL
- Indicators to discontinue cholinesterase inhibitors
- Persistent decline in MMSE and ADL or IADL
- Intolerable side effects
- MMSE <10 with dependency in all ADLs
- Severe Dementia with minimal functional capacity (bedridden, non-verbal)
- Management: Medications
- Acetylcholinesterase Inhibitors
- Efficacy
- Improve neuropsychiatric scores 7 points
- Seven point improvement equals ~1 year of decline
- Benefits may persist for 1-2 years
- Rogers (1998) Arch Intern Med 158:1021-31
- Meta-analysis shows marginal benefit to risk ratio
- Where NNT is Number Needed to Treat
- NNT for global improvement: 10
- NNT for cognitive improvement: 12
- NNT for significant side effects to stop med: 16
- Lanctot (2003) CMAJ 169:557-64
- Agents
- Donepezil (Aricept): Preferred agent
- Delays Nursing Home placement by 17-21 months
- Geldmacher (2003) J Am Geriatr Soc 51:937-44
- Galantamine (Reminyl)
- Rivastigmine (Exelon)
- Adverse effects limit use (new patch may be better tolerated)
- Tacrine (Cognex)
- Not used now due to hepatotoxicity
- N-Methyl-D-Aspartate (NMDA) Receptor Blocker
- Memantine (Namenda, Ebixa in Europe)
- Dose: Start 5 mg PO qd and titrate to 10 mg PO bid
- Indicated only in moderate to severe Dementia
- Can improve cognition and function
- Consider as alternative to cholinesterase inhibitor (e.g. Aricept) if side effects limit use
- Memantine may be better tolerated than cholinesterase inhibitors
- Previously added on to cholinesterase inhibitor protocol for added benefit
- Combination therapy no longer recommended due to low efficacy (only helped 1 in 12)
- Combination therapy is associated with gastrointestinal side effects, Bradycardia and Syncope
