Q&A: Start of new era for Alzheimer’s treatment

Researchers say we appear to be at the start of a new era for Alzheimer’s treatment. Trial results published in January showed that for the first time a drug has been able to slow the cognitive decline characteristic of the disease. The drug, lecanemab, is a monoclonal antibody that works by binding to a key protein linked to the malady, called amyloid-beta, and removing it from the body. Experts say the results offer hope that the slow, inexorable loss of memory and eventual death brought by Alzheimer’s may one day be a thing of the past.
