With the elderly beginning to outnumber the young around the world, workers, employers, and policymakers are rethinking retirement — what work we do, when to stop, and how to spend our later years.
The global demographic transition, described by a panel Thursday at the Harvard T. H. Chan School of Public Health, is tied to rapidly expanding life spans and declining birthrates. While it is furthest along in developed nations such as Italy, Japan, Germany, and France — with the United States not far behind — it is also a factor in rapidly developing nations like China and India.
The risk of developing dementia is decreasing for people with at least a high school education, according to an important new study that suggests that changes in lifestyle and improvements in physical health can help prevent or delay cognitive decline.
Building on research reported last year, Harvard Stem Cell Institute (HSCI) researchers at Brigham and Women’s Hospital have succeeded in identifying the neurons that secrete the substance responsible for the plaques that build up in the brains of Alzheimer’s disease patients.
The work has been published in the Journal of Neuroscience.
A man - let’s call him Paul - decides to undergo genetic testing to determine his risk of developing Alzheimer’s disease. Paul’s doctor reports back that he has elevated risk for that and another life-threatening illness: heart disease. How does Paul react?
Doctors have long worried that unanticipated genetic test results could harm patients, leading to depression, stress, or despondence.
Aging is one of the most mysterious processes in biology. We don’t know, scientifically speaking, what exactly it is. We do know for sure when it ends, but to make matters even more inscrutable, the timing of death is determined by factors that are in many cases statistically random.
Researchers in the lab of Walter Fontana, Harvard Medical School professor of systems biology, have found patterns in this randomness that provide clues into the biological basis of aging.
The National Institutes of Health (NIH) today released the NIH-Wide Strategic Plan, Fiscal Years 2016–2020: Turning Discovery Into Health, which will ensure the agency remains well positioned to capitalize on new opportunities for scientific exploration and address new challenges for human health.
Several neurological disorders, such as Alzheimer’s disease, are characterized by proteins that accumulate in the brain. One protein, called tau, clumps into twisted threads known as tangles. These are a hallmark of Alzheimer’s disease and several other neurodegenerative disorders known as tauopathies.
Alzheimer’s disease affects one of every nine Americans age 65 or older, and some experts estimate that this number will double by 2050. As more and more people develop memory loss, individuals are finding creative ways to help those afflicated. One of these unlikely places? Museums.
