For the first time, scientists say, they have evidence that using a biologic drug to remove sticky beta amyloid plaques from the brains of people destined to develop Alzheimer’s dementia can delay the disease.

An early Alzheimer's treatment that removes amyloid plaques from the brain many years before symptoms arise may help delay the onset of dementia, a clinical trial suggests.

A method for slowing disease progress in Alzheimer's patients may also delay onset in people predisposed to the disease who are yet to show symptoms. The just-published results from a clinical trial on an experimental drug targeting amyloid plaque buildup suggest the treatment can indeed put the brakes on cognitive decline,
