People over 65 shouldn’t take three or more medicines that act on their brain and nervous system, experts strongly warn, because the drugs can interact and raise the risk of everything from falls to overdoses to memory issues. But a new study finds that 1 in 7 people with dementia who live outside nursing homes are taking at least three of these drugs.
LifeBridge Health recently announced the launch of its “Care Happens Here” mobile unit, which will bring a wide range of healthcare testing and treatment services, including COVID-19 vaccinations, to vulnerable communities throughout central Maryland.
Nursing homes with the largest proportions of non-White residents experience 3.3 times more COVID-19 deaths than do nursing homes with the largest proportions of White residents, according to a new study from the University of Chicago.
Physicians understand frailty as a dysregulation among multiple systems in the body that make it less resilient and unable to recover completely when faced with a physical challenge such as injury or illness. “Defining frailty on a scientific level, however, has been a challenging task,” explains Ravi Varadhan, Ph.D., associate professor of oncology in the Division of Biostatistics and Bioinformatics at the Johns Hopkins Kimmel Cancer Center.
A meta-analysis finds that vision impairment and blindness are tied to an increased risk of mortality, prompting the need to address global eye health disparities.
In a study published in the March 5, 2021 online edition of Cerebral Cortex, researchers at University of California San Diego School of Medicine found that specific regions of the brain respond to emotional stimuli related to loneliness and wisdom in opposing ways.

During the COVID-19 pandemic, Johns Hopkins Medicine Media Relations is focused on disseminating current, accurate and useful information to the public via the media. As part of that effort, we are distributing our “COVID-19 Tip Sheet: Story Ideas from Johns Hopkins” every other Wednesday.
Researchers at UC San Diego School of Medicine and elsewhere have identified a new drug that could prevent AD by modulating, rather than inhibiting, a key enzyme involved in forming amyloid plaques.
Eighty percent of Americans over 50 say their primary care doctor hasn’t asked about their hearing in the past two years, and nearly as many haven’t had their hearing checked by a professional in that same time, according to a new national poll report.
As the U.S. population ages, more hospitals are implementing geriatric emergency department (GED) programs with specialized staff focused on transitional care for older adults. A new study finds that providing specialized geriatric emergency care results in lower Medicare expenditures up to $3,200 per beneficiary.
What are some of the critical determinants of a healthy and independent lifestyle for older adults?
As people age, it’s natural to experience thinner, drier skin and an increase in wrinkles and other signs of aging. However, sometimes one’s environment and lifestyle choices can cause the skin to age prematurely. Although there is no way to prevent your skin from aging, dermatologists from the American Academy of Dermatology say it’s possible to prevent premature skin aging by following a few simple steps.
Today, the Honourable Patty Hajdu, Minister of Health, and the Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry, announced an investment of $3.34 million in research to understand the health impacts of extended periods of inactivity and the effectiveness of preventative measures to mitigate the impact of inactivity on our health.

In a study released Feb. 22 in JAMA Internal Medicine researchers found that six 20-minute telephone calls over eight weeks coaching participants on how to get better sleep improved their sleep, pain, and daytime function. The improvements in sleep and daytime function persisted 12 months after treatment. One of the lead investigators who has been researching age and sleeping for 40 years offers great tips on getting better sleep. Just because you are aging, does NOT mean your sleep needs to get worse.

For many of us, as we get older the skin on our face begins to sag and we seem to lose volume around our eyes, cheeks and chin. Is gravity taking its toll in our later years or do we lose fat over the course of several years that many of us associate with youth, vibrancy and energy? Understanding the cause is paramount to how plastic surgeons treat the signs of facial aging.
A grant-funded project will produce single-molecule images of the interaction that produces a protein key to Alzheimer's Disease.
