News Topical, Digital Desk : Obesity has become a common problem in today's fast-paced life. It not only affects our heart, liver, and joints, but scientists now warn that it can also be dangerous for our brains. A recent study has revealed that obesity may increase the risk of serious diseases like Alzheimer's.
Fat tissue sends dangerous messages
Scientists have found that fat tissue doesn't just store fat, it also communicates with different parts of the body. When a person is obese, this fat tissue sends chemical signals to the brain via microvesicles that can damage brain cells.
These signals lead to the accumulation of a protein called amyloid-β in the brain, a hallmark of Alzheimer's disease. This protein gradually weakens memory and learning.
The danger crosses the blood-brain barrier
Normally, our brain is protected by a protective wall called the blood-brain barrier. However, in the case of obesity, these harmful vesicles can penetrate this barrier. This means that fat is no longer confined to the stomach or thighs; it can reach deep inside the brain and cause damage. This discovery demonstrates a deep biological connection between obesity and the brain, which until now was not fully understood by science.
New direction found in the study
The study, published in "Alzheimer's & Dementia: The Journal of the Alzheimer's Association," was conducted by scientist Stephen Wag and his team. They say that obesity may now be among the leading causes of dementia in many countries, including the United States.
The research found that the composition of lipids (fat molecules) in the vesicles of obese and normal-weight individuals differs. This difference determines how quickly amyloid-β protein accumulates in the brain. This effect was clearly observed in laboratory tests using mice and human fat samples.
Can Alzheimer's be prevented by controlling obesity?
Researchers believe that in the future, targeting these micro-messengers and blocking their harmful signals could reduce the risk of diseases like Alzheimer's . In other words, disrupting this "fat-to-brain" communication associated with obesity could offer a new way to protect the brain.
Healthy weight, healthy brain
This study offers a profound message: obesity is not only a threat to the body, but also to the mind. A healthy diet, regular exercise, and an active lifestyle not only keep the body lean but also strengthen memory and mental health. Overall, if we can control our weight, we may be one step away from serious diseases like Alzheimer's.
