Previously, scientists have identified 12 factors that lead to dementia. A new study has shown that two more factors can be added to the list, including bad cholesterol. As it turned out, in its absence, the risk of dementia is 50% lower.
It is known that 12 factors increase the risk of dementia. Earlier The Lancet said that among them are high blood pressure, obesity, alcohol abuse, nicotine addiction, physical inactivity, traumatic brain injury, social isolation, hearing problems, depression, brain activity and air pollution.
But this is not the whole list, assure experts from the Lancet Commission.
A study conducted by scientists in 2024 showed that the factor that increases the risk of dementia is also bad cholesterol. In addition, vision problems completed the list.
Scientists managed to prove that high cholesterol leads to dementia in 7% of cases, and vision impairment in the elderly - in 2%.
Clogging vessels, "bad" cholesterol narrows their patency, which leads to circulatory disorders. As a result, organs experience oxygen deficiency, including the brain. Reduced vision also affects the work of various brain structures.
As it turned out, in the absence of these two factors, the risk of dementia is reduced by 50%.
Meanwhile, earlier, a doctor-neurologist and candidate of medical sciences Maria Cherdak said that people with diabetes have a 3-fold higher risk of dementia. It became known that in diabetes the body's sensitivity to insulin is disturbed, so glucose does not get into the cells of the body and, accordingly, into the brain.
Among other things, according to Chinese scientists, obesity in the area of arms and abdomen also leads to dementia.

At the same time, according to British scientists, dementia can be prevented by proper nutrition.
