Nearly half of all dementia cases could be delayed or prevented altogether by addressing 14 possible risk factors, including vision loss and high cholesterol.
That is the key finding of a new study that we and our colleagues published in the journal The Lancet.
Dementia, a rapidly increasing global challenge, affects an estimated 57 million worldwide, and this number is expected to increase to 153 million by 2050 worldwide. Although the prevalence of dementia is on the decline in high-income countries, it continues to increase in low- and middle-income countries.
