WHO: Modifiable factors could cut up to 45% of dementia risk

The World Health Organization says up to 45% of dementia risk could be prevented or delayed by addressing modifiable factors such as tobacco and alcohol use, social isolation, physical inactivity, air pollution, and the management of chronic conditions like hypertension and diabetes, with a push for early awareness, integrated care, and investment since there is no cure and the global cost of dementia runs about $1.3 trillion annually.
