As people age, a normal brain protein known as amyloid beta often starts to collect into harmful amyloid plaques in the brain. Such plaques can be the first step on the path to Alzheimer’s dementia. When they form around blood vessels in the brain, a condition known as cerebral amyloid angiopathy, the plaques also raise the risk of strokes.
Imagine surgeons performing surgery with the assistance of augmented reality glasses. Or doing complex, minimally invasive procedures through an incision smaller than your fingernail.
