New study says percent of people developing dementia each year is falling

From STAT NEWS:

The long-running Framingham Heart Study has found that “the rate of dementia was 3.6 percent in the late 1970s and early 1980s, falling to 2.8 percent a decade later, 2.2 percent a decade after that, and 2 percent in the late 2000s and early 2010s. That means 44 percent fewer Framingham-ites were developing dementia in the most recent period than in the late 1970s, after taking into account that the group had aged. Rates of vascular dementia fell the most. Rates of Alzheimer’s also declined, but the drop just missed being statistically significant.”
