Scientist hail ‘huge breakthrough’ in trials of drug slowing Alzheimer’s disease

Scientists have welcomed clinical trials of a new drug which could help to slow cognitive decline in people with Alzheimer’s disease.

The trials show that the drug – called lecanemab – had some impact in patients with early stages of the disease, which affects some 30 million people around the world.

Experts say although it’s no miracle cure – it does represent a huge breakthrough.
