Prevention may slow rate of dementia cases

Aging is a risk factor for dementia and Alzheimer’s disease, the most common dementia. Because the number of older people is increasing, so is the prevalence of dementia cases globally. However, in an editorial, several physicians report that a number of population studies show that for “younger” older people, the number of new cases of dementia may be declining. They also noted that people who do get dementia may do so later in life, closer to the time of death.
