Tracking brain wave activity in individuals at high risk for Alzheimer’s disease may be a promising new method for early detection, according to a new Canadian study by researchers at Baycrest Centre for Geriatric Care in Toronto, Ontario.
This is possible because brain waves tend to slow down in certain regions likely to be affected by the disease next, even before neurons have been lost.
The findings, published online in the journal Human Brain Mapping, show that individuals potentially in the early stages of Alzheimer’s disease (mild cognitive impairment) and those with a rare form of language dementia (primary progressive aphasia) exhibited sluggish brainwaves and subtle signs of damage in the brain regions responsible for memory and planning.
