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.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

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.

Why this might work

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.

  1. Study: Global Burden of Alzheimer's disease and other dementias in adults aged 65 years and older, 1991–2021: population-based study

    This 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.
