NBC News (7/16, Fox) reports that despite the many warnings that “Obamacare was going to create a crush of pent-up medical demand,” a new study shows that visits to physicians actually “appear to be down slightly over 2013.” A research team at Athenahealth found that “Most specialty types did not see higher new patient visit rates for the first five months of 2014 than they did in the same period in 2013. Indeed, with the exception of pediatrics, all specialties are seeing lower new patient visit rates in 2014 compared to 2013.”

The AP (7/16, Marchione) reports that the dementia rate “is falling in the United States and some other rich countries.” What’s more, the onset of dementia, including Alzheimer’s, appears to be happening later in life. Investigators came to both conclusions after analyzing data from the “federally funded Framingham study” that “tracked new dementia cases among several thousand people 60 and older in five-year periods starting in 1978, 1989, 1996 and 2006.”

Dallas Anderson, chief of epidemiology at the National Institute on Aging, said, “For those who get the disease, it may come later in life, which is a good thing.”

HealthDay (7/15, Doheny) reports that research presented at an international meeting of the Alzheimer’s Association suggests that “for certain seniors, widowhood may…delay dementia.” The study started with approximately “3,800 married men and women starting to show some brain decline.” Investigators found that participants “who were widowed progressed to dementia at age 92 roughly, while those who didn’t lose a spouse were demented by age 83 – nearly a 10-year difference.”

In continuing coverage, the New York Times (7/2, Reynolds) “Well” blog reports that according to a study (7/2) published in the May issue of the journal Frontiers in Aging Neuroscience, “exercise may help to keep the brain robust in people who have an increased risk of developing Alzheimer’s disease.” For the study, researchers from the Cleveland Clinic “recruited almost 100 older men and women, aged 65 to 89, many of whom had a family history of Alzheimer’s disease.”

All participants underwent brain scans before and after the study. Researchers found that “the brains of physically active volunteers at high risk for Alzheimer’s disease looked just like the brains of people at much lower risk for the disease.”
