Promising new research conducted last year at the Salk Institute for Biological Studies has shown that marijuana extracts may hold a key to treating Alzheimer’s disease. The next step: To conduct tests on mice and, if the results are promising, move on to human trials. But Salk Institute researchers have run into a major hurdle, and not a scientific one: the federal government.
Any exercise is usually considered better than no exercise, but a new study indicates interval training — interspersing high and low speed levels during activities such as biking — is best at reversing age-related declines in muscle cells.
Whether it’s transgender teens trying to find informed providers to help them navigate their life-changing physical transformations; lesbians who are less likely than others to get preventive breast-cancer care; or gay and bisexual men who had to push an indifferent health care system to respond to the early AIDS epidemic, LGBT individuals have faced many challenges in the health space. As researchers look for ways to improve LGBT health, one issue hasn’t received much attention with respect to this population, although it is an equal-opportunity process: aging.
Every 66 seconds this year, an American will develop Alzheimer’s disease, according to the Alzheimer’s Association annual report, released Tuesday. By the year 2050, that number is expected to double to one every 33 seconds. Those startling statistics are mirrored worldwide. In 2016, the World Alzheimer’s Report estimated that 47 million people around the globe had dementia.
New research suggests that a compound commonly found in red wine and some fruits may protect our neurons against the unwanted effects of aging. In fact, the study suggests that the benefits may be equivalent to those of dieting and exercising.
Are there health benefits to staying in the work force longer?
The scientific research is inconclusive, though it tends to tilt toward “yes.” This is particularly pronounced among people who find work fulfilling in the first place, who tend to be office workers, teachers and others whose workplace is not, say, a factory or a construction site.
“The context of aging and work is changing,” said Jacquelyn B. James, a psychologist and co-director of the Center on Aging and Work at Boston College. In addition to health and longevity, she said education is a factor. “This is one of the most educated generations in history,” Dr. James said. “A lot of the jobs people are continuing in are fields in which you use the mind, not the body.”
Alzheimer’s disease is rewriting the rules of drug discovery, with a handful of companies abandoning caution to keep pursuing an elusive hypothesis because the potential payoff is so great.
When it comes to retirement, the anxiety can be worse than the reality.
At least that’s how retirees and pre-retirees in four countries — the United States, Canada, the United Kingdom and Australia felt, according to a research report from Malvern, Penn.-based investment management giant Vanguard Inc. In both the U.S. and Canada, 65% of recent retirees each felt highly satisfied with their financial situations compared with 53% of pre-retirees in the U.S. and 46% in Canada. In the U.K., 78% of recent retirees were highly satisfied with their financial situations, compared with 52% of pre-retirees.
John Hoch, a graying, bespectacled 51-year-old, has struggled with homelessness, alcohol and drug addiction, depression and anxiety, and has been in and out of prison for much of his adult life. But when he is released from the Prince William County Adult Detention Center in April, he believes things will be different, in part because of a class he just completed that teaches inmates how to manage chronic health problems.
