Size of the treatment effect on cognition of cholinesterase inhibition in Alzheimer's disease

Abstract: Background: Six cholinesterase inhibitors (ChEIs) have been tested in people with Alzheimer's disease, using methods currently required for regulatory approval. The clinical importance of their treatment effects is controversial. Objective: To determine whether cholinesterase inhibition produces treatment effects in Alzheimer's disease that are large enough to be clinically detectable.

“…[11][12][13][14][15][16][17][18][19][20] A recently published systematic review analyzed the results of 43 placebo-controlled randomized trials (24 of donepezil, 10 of galantamine and 9 of rivastigmine) involving a total of 13 717 participants. 20 The duration of the drug intervention in most (24/43) of these studies was 23-26 weeks; it was 52 weeks or longer in 5 trials (4 of donepezil, 1 of rivastigmine).…”

“…27 The randomized controlled trials of cholinesterase inhibitors have shown consistent benefits, albeit modest and of debatable clinical significance, with treatment on patients' cognition and global clinical state. [11][12][13][14][15][16][17][18][19][20] The cognitive measure most commonly used in these studies was the cognitive section of the Alzheimer's Disease Assessment Scale. 28 This scale comprises 11 items that test a range of cognitive domains.…”

“…Estudos controlados por placebo mostram que os benefícios são geralmente observados a partir de 12 a 18 semanas e, possivelmente, desaparecem após seis a oito semanas da interrupção do tratamento (Jann, 1998 (Lanctôt et al, 2003;Rockwood, 2004). Dada a ausência de preditores clínicos ou biológicos de eficácia, justifica-se a prescrição de um inibidor da colinesterase para todos os pacientes com diagnóstico de DA leve ou moderada, desde que não haja contra-indicações para o seu uso.…”
