Dementia Is On the Wane . . . But Maybe Not For Long

A new study says that dementia has been on the wane for multiple decades:

The risk for a person to develop dementia over a lifetime is now 13 percent lower than it was in 2010. Incidence rates at every age have steadily declined over the past quarter-century….In 1995, a 75-year-old man had about a 25 percent chance of developing dementia in his remaining lifetime. Now that man’s chance declined to 18 percent, said Dr. Albert Hofman, chairman of the department of epidemiology at the Harvard School of Public Health and the lead author of the new paper.

But wait:

In a reversal of trends, American baby boomers scored lower on a test of cognitive functioning than did members of previous generations, according to a new nationwide study.

Findings showed that average cognition scores of adults aged 50 and older increased from generation to generation, beginning with the greatest generation (born 1890-1923) and peaking among war babies (born 1942-1947). Scores began to decline in the early baby boomers (born 1948-1953) and decreased further in the mid baby boomers (born 1954-1959).
While the prevalence of dementia has declined recently in the United States, these results suggest those trends may reverse in the coming decades, according to study author Hui Zheng, professor of sociology at The Ohio State University.

Trust the boomers to screw things up. On the other hand, this might be the result of juvenile lead poisoning, and that’s the fault of the Greatest Generation. Greatest indeed.

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
