Dementia: Globally, there were 57 million cases of dementia in adults in 2019, which could increase to 153 million by 2050. This increase is due to increase in population and aging population. According to researchers, there are four main causes of dementia – smoking, obesity, high blood sugar and low education. Researchers have made future predictions based on these four factors.
Researchers have suggested that improving global education access could reduce the prevalence of dementia in 6.2 million people. But due to the increase in obesity, high blood sugar and smoking, 68 lakh cases of dementia will increase further. That is, only the spread of education is not going to work.
Dementia cases will increase in every country
Studies show that cases of dementia will increase in every country. The lowest growth is estimated to be in high-income Asia Pacific (53 percent) and Western Europe (74 percent). According to estimates, the largest increase will be in North Africa and the Middle East (367 per cent) and Eastern Sub-Saharan Africa (357 per cent).
The number of dementia cases in the UK is estimated to increase by 75 per cent. In 2019, there were only 907,000 cases, which will increase to about 16 lakh in 2050. The number of dementia cases in Western Europe is expected to increase by about 74 percent. Where there were 80 lakh cases in 2019, it will be around 1.5 crore in 2050.
A relatively small increase in cases is expected in Greece (45 per cent), Italy (56 per cent), Finland (58 per cent), Sweden (62 per cent) and Germany (65 per cent).
Calling for aggressive containment efforts
The Global Burden of Disease Study is the first to provide a prognosis estimate for adults 40 years of age and older in 195 countries around the world. Experts are calling for more aggressive prevention efforts to reduce the risk of dementia through lifestyle factors such as education, diet and exercise.
Lead author Emma Nichols, from the Institute for Health Metrics and Evaluation at the University of Washington in the US, said: “Our study provides a better prognosis for dementia at the global as well as country level, providing new information to policymakers and public health experts. Meet up.
He said that we need to pay more attention to prevention and control of risk factors that cause dementia. To have the greatest impact we need to reduce the major risk factors in each country.
Worldwide, more women are affected by dementia than men. The number of women with dementia exceeded men with dementia by 100 to 69 in 2019, and this pattern is expected to persist into 2050. IHME co-author Dr Jamie Steinmetz said Alzheimer’s disease can spread to different parts of the brain in women than in men.
