Scientists at the University of Edinburgh (UK) found that smoking hypertension, obesity and diabetes were responsible for the premature aging of our brains and the reduction of its volume.
According to the study published in the European Heart Journal, the 9,772 volunteers aged 44 to 79 years underwent magnetic resonance imaging to look for links between the structure of different parts of the brain and the other seven. factors that contribute to damage to the blood vessels and worsening of the blood supply to the central nervous system. Among the factors badyzed, the researchers mentioned smoking, high blood pressure, high blood pressure, diabetes, high cholesterol and obesity, depending on the index of body mbad (BMI) and height-to-size ratio. hip
The strongest links have been found in areas of the brain responsible for our more complex thinking abilities that have deteriorated during the development of the disease. 39: Alzheimer's and dementia
It turned out that all factors, except high cholesterol, including smoking, blood pressure and diabetes, contribute to decrease the amount of gray matter . In addition, brain volume decreased and the state of white matter deteriorated . This relationship is shown more in people of average age.
The study showed that with the increased risk of vascular injury, brain volume was reduced by 3% compared to the norm. and the white substance suffered 1.5 times more damage.
