Study Questions Effect of Drugs on Alzheimer’s Disease

According to the Guardian, a large-scale analysis of clinical trials suggests that anti-amyloid drugs for Alzheimer’s disease offer limited clinical benefit to patients. The Cochrane review finds that improvements in cognitive function and dementia severity over an 18-month period are minimal, with little measurable impact on patients’ daily functioning.

The study analysed 17 clinical trials involving more than 20,000 patients and assessed seven drugs designed to remove amyloid plaques from the brain. It also identified a higher incidence of side effects, including brain swelling and bleeding.

Some experts have criticized the methodology, arguing that the analysis combines results from older, unsuccessful drugs with those from newer treatments. They warn that this approach may distort the overall findings.

Regulators have approved several newer drugs that demonstrate modest improvements. However, some countries have declined to include them in public healthcare systems due to high costs. In the UK, a decision on public funding remains under review.The authors conclude that future research should shift towards alternative approaches to treating Alzheimer’s disease.
