According to a new study done by the University of South Australia, there is a link amid body fat and the risk of stroke or dementia. The study connects some types of body fat with the reduction in gray matter.
Gray matter is a part of the brain that has most neurons and is dangerous to cognitive function. Researcher and lead author at the Australian Centre of Precision Health, Anwar Mulugeta,
explains, ‘we found that individuals with a high level of obesity, especially those with unfavorable and neutral adiposity subtypes, have low levels of gray brain matter.
Some Types Of Body Fat Reduce The Quantity Of Gray Brain Matter
This indicates that these persons may have negotiated brain function which requires additional investigation.’
What is gray matter and cognitive function?
As per Dr. Mulugeta ‘Gray matter is a vital component of the brain rich in neuronal cell bodies, capillaries, and glial cells. It is located in many diverse parts of the brain and plays multiple roles like memory, learning, cognitive function, attention, and muscle control.’
Also, Dr. Christina E. Though not involved in the study, explained ‘age-related cognitive function and dementia both linked and reduce grey matter termed as atrophy.’ Also ‘ for example, Alzheimer’s disease dementia is linked with reduction gray matter, also known as hippocampal atrophy, which extends to other parts as the disease progresses. So we can say that the quantity of gray matter indicates cognitive health.’
About the obesity
Nowadays, obesity is in the rise globally, and according to WHO, about two billion adults at present are struggling with overweight issues, and about 650 billion of them have obesity. This problem also can be now seen in children as about 40 million kids less than five years old and people with 15 to 19 years are suffering from obesity.
As per WHO reports, there is a connection between obesity and many other health issues. These health-related problems include cardiac disease, i.e., heart disease and stroke, diabetes, osteoarthritis, some cancers, and musculoskeletal disorders.
Types of obesity
Dr. Mulugeta says, ‘in this study, we examine the link of persons within three metabolically types of obesity, i.e., neutral, favorable and unfavorable to know whether certain weight groups were more prone than others.’ The author added that the study explains three types of obesity ‘persons with the rise in genetic load for unfavorable adiposity are categorized by fat accumulation around internal organs and abdomen, high cholesterol and high risk of type 2 diabetes and coronary disease.’ He continued and said, ‘people with favorable adiposity have aft accumulation around hip and less around internal organs. Therefore, these people are less prone to type 2 diabetes and linked with heart disease. Also, people with neutral adiposity are not associated with type 2 diabetes and links with coronary diseases’.
According to senior author Prof. Elina Hypponen, ‘if an individual has a normal weight, the excess weight around the abdominal area may be the concern. ‘Author added that obesity is a complex condition, especially people with excess fat around internal organs can have a harmful effect on health.’ She also clarifies that ‘ obesity in midlife is linked with poor cognition and high risk of cognitive decline. On the other hand, increased body mass index can be linked with better cognition and may affect overall health.’
According to the study, there is actually a connection
As per the study, it is clear that for an extra every three kg of body weight in an individual of average height, the quantity of gray matter decreases by 0.3 percent. Therefore, although Dr. Mulugeta notifies, ‘we do not find conclusive proofs to connect certain obesity subtype with stroke or dementia. In its place, as per study explains the probable part of inflammation as well as metabolic abnormalities and how they can contribute to obesity and gray matter volume reduction.’
