Diabetes, Hearing Loss Linked To Dementia Risk In India: Study
A study looked at 25 years of data in India and found that early diabetes, hearing loss, not exercising enough, and being underweight can all raise the chance of getting dementia.
Women and people in rural areas are more likely to have dementia, maybe because doctors miss the warning signs.
Diabetes can make dementia risk two or three times higher, and hearing loss can raise it by almost 60%.
Even a short walk each week can lower the risk by 40%, but many adults don’t get enough exercise.
Not having enough education or untreated vision problems also add to the risk.
The study suggests that fixing these problems could stop or delay dementia in many people.
Early-onset diabetes, hearing loss, inactivity, and undernutrition are key modifiable dementia risk factors in India.
Women and rural residents have higher dementia prevalence, partly due to underdiagnosis of risk factors.
Diabetes can double or triple dementia risk; hearing loss raises risk by 59% and doubles Alzheimer’s risk.
Only 35 minutes of weekly physical activity lowers dementia risk by 41%, yet 57% of adults fall short of this level.
Limited education and untreated vision loss account for 22% and 14% of modifiable dementia risk, respectively.
