Meds for Alzheimers – no real benefit

Dr. Weeks’ Comment:   Many drugs have been offered for Alzheimer’s patients and none of them help to any significant degree.  The conclusion of the article below  is  that  cognitive enhancers in general have minimal effects on cognition.

But seed nutrition has been found to be VERY HELPFUL for Alzheimer’s   as has curcumin also.    

Remember – Alzheimer’s is made worse by INFLAMMATION.

Abstract and Introduction

Abstract

Background/Objectives To examine the comparative effectiveness and safety of cognitive enhancers for Alzheimer’s disease (AD).

Design Systematic review and Bayesian network metaanalysis (NMA).

Setting MEDLINE, EMBASE, Cochrane Library, CINAHL, Ageline (inception–March 2016).

Participants Individuals with AD in randomized controlled trials (RCTs), quasi-RCTs, and nonrandomized studies.

Intervention Any combination of donepezil, rivastigmine, galantamine, or memantine.

Measurements Two reviewers independently screened titles, abstracts, and full-texts; abstracted data; and appraised risk of bias.

Results Twenty thousand three hundred forty-three citations were screened, and 142 studies were included (110 RCTs, 21 non-RCTs, 11 cohort studies). NMA found that donepezil (Mini-Mental State Examination: mean difference (MD) = 1.39, 95% credible interval (CrI) = 0.53–2.24), donepezil+memantine (2.59, 95% CrI = 0.12–4.98), and transdermal rivastigmine (2.02, 95% CrI = 0.02–4.08) improved cognition more than placebo. NMA found that donepezil (Alzheimer’s Disease Assessment Scale–cognitive: MD = −3.29, 95% CrI = −4.57 to −1.99) and galantamine (MD = −2.13, 95% CrI = −3.91 to −0.27) improved cognition more than placebo. NMA found that donepezil+memantine (MD = −5.23, 95% CrI = −8.72 to −1.56) improved behavior more than placebo. NMA found that donepezil (MD = −0.32, 95% CrI = −0.46 to −0.19), donepezil+memantine (MD = −0.57, 95% CrI = −0.95 to −0.21), oral rivastigmine (MD = −0.38, 95% CrI = −0.56 to −0.17), and galantamine (MD = −3.79, 95% CrI = −6.98 to −0.59) improved global status more than placebo. NMA found that galantamine decreased the odds of mortality (odds ratio = 0.56, 95% CrI = 0.36–0.87). No agent increased risk of serious adverse events, falls, or bradycardia. Some increased risk of headache (oral rivastigmine), diarrhea (oral rivastigmine, donepezil), nausea (oral rivastigmine, donepezil, galantamine), and vomiting (oral rivastigmine, donepezil, galantamine).

Conclusion An exhaustive review of the literature involving 142 studies demonstrated that cognitive enhancers in general have minimal effects on cognition according to minimal clinically important difference and global ratings. The drugs appear safe, but this must be interpreted cautiously because trial participants may have less comorbidity and fewer adverse effects than those treated with these drugs in clinical practice.
