The scientific journal of the American Academy of Neurology has published a study which tells about the memory loss and the loss of grey matter in the brain.

Scientists who scanned brains of older people with memory loss and no other cognitive impairments like thinking, or reasoning found that they had reduced gray matter density which was previously found in people with Alzheimer’s disease or mild cognitive impairment (MCI).

The study included 120 people over the age of sixty who had mild memory problems but normal other cognitive functions. The brain scans showed a 3% reduction in gray matter density in an area important for memory comparing to the 4% reduction in those diagnosed with mild cognitive impairment.

This is why the researchers suggested that the people who only had remembering problems could still be in danger of developing Alzheimer’s disease or suffering from severe dementia. They emphasize the importance of reporting the cognitive complaints in older adults and their evaluation and monitoring especially now when the drugs are being developed to slow and prevent Alzheimer’s disease.
