Scientists at the University of Edinburgh in the UK have discovered that the Smoking, hypertension, obesity and diabetes They cause the premature aging of our brain 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 seven factors in question. damage the blood vessels and aggravate the blood supply to the central nervous system. Among the factors analyzed, the researchers mentioned smoking, high blood pressure, high blood pressure, diabetes, high cholesterol and obesity, depending on the index of body mass (BMI) and height-to-size ratio. hip
The strongest links were found in areas of the brain that are responsible for our thinking abilities more complex and deteriorate during the development of Alzheimer's disease and dementia.
All factors except high cholesterol, including smoking, blood pressure and diabetes, have been shown to contribute to decrease the amount of gray matter. In addition, brain volume has decreased and the condition of the white matter deteriorated. To a greater extent, this relationship has manifested itself in people of average age.
The study showed that with an increased risk of vascular lesions, brain volume it has been reduced by 3% compared to the norm, and the white matter had 1.5 times more damage.
