U.S. Spends More on Dementia than Either Heart Disease or Cancer
At as much as $215 billion annually, the cost of dementia care in the United States is now higher than the costs for either heart disease or cancer, according to a new study in the New England Journal of Medicine. That includes the costs for both professional and family care. And the costs will only rise as the population ages, with as many as 14 million Americans expected to have Alzheimer’s by 2050, according to HealthDay. "It's not a happy situation," said lead researcher Michael Hurd, a senior principal researcher at the nonprofit research institute RAND. "A lot of the costs fall on families, and right now, there's no solution in sight." Read more on aging.
Brain Stimulation Could ‘Turn Off’ Compulsive Drug-Taking
Targeting a specific region of the brain could help turn off addictive behavior, according to a new study in the journal Nature. Researchers at the Intramural Research Program of the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, and the University of California, San Francisco were able to reduce compulsive cocaine-seeking in rates by stimulating their prefrontal cortexes. They believe this technique could ultimately be used to stop compulsive drug-taking in humans. “We already knew, mainly from human brain imaging studies, that deficits in the prefrontal cortex are involved in drug addiction,” said NIDA Director Nora D. Volkow, MD. “Now that we have learned how fundamental these deficits are, we feel more confident than ever about the therapeutic promise of targeting that part of the brain.” Read more on addiction.
Study: Black Men Wait Longer to Begin Prostate Cancer Treatment
Black men wait longer than white men to begin prostate cancer treatment after diagnosis, according to a new study in the journal Cancer. Researchers at the University of North Carolina found a delay of seven days with early prostate cancer and nine days with aggressive prostate cancer. As the study looked at Medicare data, the researchers know all the men were insured so it wasn’t a lack of insurance stopping them from seeking treatment earlier. Multiple studies also show that black men in general are less likely to be screen for cancers and to receive aggressive treatment. "Now we have shown that African American patients also wait longer for treatment,” said study leader Ronald Chen, MD, an assistant professor at UNC's Lineberger Comprehensive Cancer Center. “I think all of these disparities together add up to contribute to worse long-term survival outcomes for African American patients."
