The Claim
The global burden of Alzheimer's disease and other dementias is increasing at the fastest rate in countries with high and high-middle sociodemographic indices, with the most rapid rises in age-standardized prevalence and mortality observed in East Asia.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Alzheimer's disease and other dementias are growing most quickly in wealthier countries, especially in East Asia, where the number of cases and deaths per person is rising faster than anywhere else.
See the scientific wording
The global burden of Alzheimer's disease and other dementias is rising fastest in countries with high and high-middle sociodemographic indices, particularly in East Asia, where age-standardized prevalence and mortality trends show the most rapid increases, suggesting that economic development and aging populations are key drivers of the dementia epidemic.
High blood sugar and excess body fat cause the brain to receive less energy and trigger inflammation, which stops the brain from cleaning out toxic proteins. These proteins build up, damage nerve cells, and kill them, leading to memory loss and dementia.
What the research says
1 studyThis study shows that more older people are getting dementia worldwide, especially in countries where people are living longer — like China and South Korea — which is exactly why dementia cases are rising fastest there.
