What is bad for your heart can also shrink brain
Researchers have identified how specific cardiovascular risk factors, such as alcohol consumption, smoking, obesity and diabetes, may damage the brain, thereby increasing the risk of Alzheimer\'s disease and dementia. The researchers examined the link between cardiovascular risk factors with three main brain regions, including the hippocampus, precuneus and posterior cingulate cortex.
New York: Researchers have identified how specific cardiovascular risk factors, such as alcohol consumption, smoking, obesity and diabetes, may damage the brain, thereby increasing the risk of Alzheimer's disease and dementia. The researchers examined the link between cardiovascular risk factors with three main brain regions, including the hippocampus, precuneus and posterior cingulate cortex.
Because of each region's connection to memory retrieval, gray matter volume loss in these areas may be a predictor of Alzheimer's disease and dementia. The researchers analysed results from 1,629 individuals and divided the participants into two age groups. There were 805 participants under age 50, and 824 of age 50 and above.
The study found that risk factors of alcohol use and diabetes were associated with smaller total brain volume, while smoking and obesity were linked with reduced volumes of the posterior cingulate cortex, the area of the brain connected with memory retrieval as well as emotional and social behaviour.
