The new study, which lasted nearly 25 years, involved 8,000 people. His findings are important for the prevention of age-related dementia, and also indicate additional signs of neurodegeneration, which doctors will need to consider when examining the elderly.
Changes in the brain with the development of dementia can begin 15-20 years before the onset of the first symptoms of the disease, so scientists are constantly looking for sensitive methods for early diagnosis. A new study involving almost 8,000 people proves that diseases of the cardiovascular system at the age of 50 are an important risk factor for the development of dementia in the future, writes Science Daily.
At the start of the study, all volunteers were healthy. They were observed on average for 25 years. All participants underwent a comprehensive assessment of the state of the cardiovascular system.
Observations showed that in patients with poor heart and vascular health, the incidence of dementia was 3.2 per 1000 people. For the most healthy participants, this indicator was 1.3.
The authors emphasize that even a slight improvement in the risk factors of cardiovascular disease at the age of 50 can reduce the risk of dementia.
“It is important to pay attention to the first signs of heart and vascular diseases on time and pay special attention to the prevention of conditions to strengthen cognitive skills in the future,” the scientists said.
Another major study showed that another risk factor for dementia is the person’s social activity. It turned out that an active attitude and sociability positively affect the brain of older people. According to scientists, social activity – regular meetings with friends make the brain form new connections that make it more resistant to degeneration. Interestingly, communicating with relatives has a different effect. Researchers from the UK have discovered a new risk factor for age-related dementia – social activity. The higher it is, the better.
