A study by the American Academy of Neurology has shown that people with diabetes significantly increase the risk of developing dementia in the elderly.
American researchers insist on entering diabetes into a list of risk factors for the development of dementia. The number of people suffering from diabetes is constantly increasing, but in the light of new facts, diabetes is becoming even more important.
Dementia, or acquired dementia, in varying degrees of severity is manifested in 10-15% of all elderly people over the age of 60 years. Senile dementia leads to changes in personality and character, reduction of intellectual and logical abilities, influences familiar skills, worsens interpersonal relationships, leads to memory loss, irritability and even the impossibility of self-service.
The most common cause of dementia in the elderly - Alzheimer's disease, but also dementia can be caused by vascular pathology, Parkinson's disease, and age-related atrophic changes in the brain.
People with diabetes are in the risk group for developing dementia caused by Alzheimer's disease, as well as other types of dementia, such as vascular dementia, which develops when damage to the vessels of the brain, which causes the brain to receive no sufficient amount of oxygen.
The study involved 1017 people aged 60 and over. Patients were periodically tested for glucose tolerance to detect the development of diabetes mellitus. On average, participants underwent regular examination for 11 years, after which they were tested for dementia. During the study, dementia developed in 232 people.
The study found that in people with diabetes, the probability of developing dementia doubled the probability of the same disease in people with normal blood sugar. Of the 150 people with diabetes, dementia was manifested in 41, compared with 115 people out of 559 with normal sugar in which the same disease developed.
The results remained the same, even when scientists took into account factors such as high blood pressure, high cholesterol and smoking. The risk of aging dementia was also higher in people without diabetes, but with impaired glucose tolerance or prediabetes.
The study has shown that the risk of developing dementia increases significantly if blood sugar levels remain high even within two hours of eating.
The study was published in the journal Neurology.
