Lesions linked to risk of mild cognitive impairment

Brain damage seen on brain scans may predict memory loss in old age

Areas of brain damage seen on brain scans and originally thought to be related to stroke may help doctors predict a person’s risk of memory problems in old age, according to research published in the August 11, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

Researchers tested 679 people age 65 and older without dementia for mild cognitive impairment, the stage between normal aging and dementia. Participants underwent brain scans where scientists looked for small areas of brain damage called white matter hyperintensities, often referred to as ministrokes. They also looked for infarcts, or areas of dead tissue usually called strokes. Both types of brain damage may be caused by vascular disease in the brain. … > full press release : review by MedPage Today
