pharmaceutical agents for treatment of Alzheimer's disease (Alzheimer's agent)

Adverse effects

* relative to donepezil

Management

no agent shown to improve clinically relevant outcomes[19]

associated behavioral syndromes

sleep disturbance

others (from 2001 recommendations of the American Academy of Neurology, see early intervention for Alzheimer's disease)

estrogen NOT useful, may be risk

statins may diminish rate of deterioration[14]

centrally-acting ACE inhibitors may diminish rate of deterioration[15][26]

idalopirdine, a 5HT6 receptor antagonist, failed to slow cognitive decline in patients with Alzheimer's disease[39]

cholinesterase inhibitors, memantine, & statins inappropriate in patients with advanced dementia[32]

* FDA proposes approval of new drugs for treatment of preclinical Alzheimer's disease based on changes in biomarkers without demonstration of actual clinical benefit[6]

* NICE (UK) recommends cholinesterase inhibitors & memantine no longer be used for treating Alzheimer's disease. These drugs do NOT delay institutionalization & are NOT cost-effective[8]

* NICE (UK) recommends cholinesterase inhibitor as an option for moderately severe AD (MMSE 10-20)[8]

* NICE does NOT recommend memantine except for clinical trials, OK to continue if currently prescribed medication[8]

* benefits of cholinesterase inhibitors in Alzheimer disease patients are relatively small & likely extend to only a subset of AD patients that can't be identified in advance[11]

* treatment of dementia with cholinesterase inhibitors & memantine can result in statistically significant but clinically marginal improvement in measures of cognition & global assessment of dementia[15]

* neither donepezil nor memantine significantly affects outcomes important to caregivers[22]

* continuing donepezil in patients with moderate-severe AD

* evidence is insufficient to compare the effectiveness of different pharmaceutical agents to treat dementia[15]
