Medical Network, February 2nd, a study published in the online edition of the American "Neurology" magazine showed that over time, people with enlarged perivascular spaces may be more likely to develop cognitive problems or suffer from Alzheimer's disease than others.
.
This discovery may help the early diagnosis of Alzheimer's disease
.
The perivascular space is the fluid-filled space around the small blood vessels in the brain, which participates in the removal of waste and toxins in the brain.
The size of this space may be related to the changes in the brain caused by aging
.
Researchers from the University of New South Wales in Australia and other institutions used 8 years to track 414 elderly people aged 72 to 92
.
These elderly people passed cognitive tests at the beginning of the study and every two years thereafter, were assessed for Alzheimer's disease, and received an MRI brain scan
.
During the study period, a total of 97 people were diagnosed with Alzheimer's disease
.
Among the 31 people with the largest enlargement of the perivascular space, 12 were diagnosed with Alzheimer's disease
.
Researchers found that people with the most enlarged perivascular spaces are nearly three times more likely to suffer from Alzheimer's disease than those with less or no enlarged spaces
.
People with the most enlarged space around the cerebral vessels are also more likely to have a decline in their total cognitive scores than those with less or no increase in the space
.
The researchers pointed out that the expansion of the perivascular space may mean that the brain’s ability to remove waste is impaired, and may be a sign of cognitive decline or an increased risk of Alzheimer’s.
More research is needed to understand these enlarged cerebral blood vessels in the future.
