The Mayo Clinic reports that a form of dementia often mistaken for Alzheimer's is preventable.
Vascular cognitive impairment (VCI) can strike suddenly from a stroke. Or it may develop in the brain over the years.
As VCI advances, it cause ireversible damage to the brain and results in Alzheimer-type symptoms.
The good news is that quitting smoking, eating right, exercising, and managing stress prevents it.
