High blood pressure tied to dementia

Hypertension was linked to one of two types of mild cognitive impairment, a condition that can foreshadow the development of dementia, but not the type strongly associated with Aizheimer's diseases, according to a study published in the journal archives of Neurology.
People with mild cognitive impairment can have difficulties with language, memory, attention span or other mental functions significant enough to be noticeable to other people and to be detected in tests.
The elderly people with high blood pressure in this study often had a form of mild cognitive impairment that can be a precursor to vascular dementia, the second most common form of dementia after Aizheimer's disease. It is often associated with stroke. High blood pressure raises the risk for stroke.
