Trials present lecanemab slows cognitive decline by a few quarter in sufferers with early-stage Alzheimer’s illness.

Alzheimer’s researchers reward take a look at outcomes It is referred to as “historic” as a result of no drug has beforehand convincingly proven the underlying mechanism to gradual the illness.

Lecanemab works by clearing out a rogue protein referred to as amyloid that accumulates within the brains of Alzheimer’s sufferers.

Even when the drug is permitted within the UK, it is going to be as much as well being our bodies such because the Nationwide Institute for Well being and Care Excellence (NICE) and the Scottish Medicines Consortium (SMC) to determine whether or not the drug is definitely worth the cash and ought to be really useful to sufferers.

However she mentioned there are causes to stay hopeful.

“Lecanemab has proven that slowing illness development is feasible and works. Now we have to step up our efforts to find new, safer remedies,” Professor Spires-Jones mentioned.
