Alzheimer’s disease is the most common form of dementia. For many years, researchers believed that its main cause was a buildup of toxic proteins. But recent findings suggest that the problem may have another origin, specifically in the bloodstream.
Contrary to a commonly held belief, dementia isn’t just about memory. Imagine the brain as a car. To run properly, this complex system depends, among other things, on an engine (our neurons, the central component) and a set of pipes (our cerebral vascular system) to deliver fuel (oxygen and nutrients) to the engine.
