Researchers say a new experimental drug could be a game changer when it comes to treating Alzheimer's disease.
Patients with early-stage Alzheimer's were given the drug aducanumab once a month for a year.
According to researchers, the drug cleared some deposits of toxic plaque from the brain.
It's that plaque that experts believe plays a crucial role in triggering the onset of Alzheimer's and memory loss.
After a year, patients on the highest dose of aducanumab had virtually no detectable signs of these deposits.
Larger studies are under way to test whether this potential breakthrough holds up.
