(CNN)An experimental drug shattered and removed toxic plaques in the brains of patients with early-stage Alzheimer's disease, researchers said Thursday.
Given to patients once a month for a year, infusions of the drug aducanumab cleared the brain of the deposits, which experts believe play a crucial role in disrupting cellular processes and blocking communication among nerve cells.
Although most aging brains contain some plaques, the brains of Alzheimer's patients tend to have much more. The disease, the most common form of dementia, has no cure, although some treatments are available to alleviate symptoms. Treatments to slow the progression or reverse it have not panned out.
