Researchers found that using a computer, playing games, and participating in social activities may reduce the risk of mild cognitive impairment. New research suggests that playing games, using a computer, and having a rich social life can keep mild cognitive impairment at bay. Our brains go through changes as we get older, and some people

Doctors use lasers and retinoic acid to treat skin damage. Scientists have now uncovered a common mechanism that links both, paving the way for new treatments. What links laser and retinoic acid treatment for sun damage? Skin damage, in the form of dark spots and wrinkles, naturally occurs as we age. Ultraviolet light from the

As women get older, they tend to have less sex. They may also find it less enjoyable than before. So far, studies have explained these tendencies by pointing the finger at physiological changes during and after menopause. What are the other factors? What prevents a woman from having sex or enjoying sex later in life?

The buildup of defective tau proteins is a prominent feature of neurodegenerative diseases such as Alzheimer’s. The faulty proteins form tangles that disrupt brain function and kill nerve cells, or neurons. Experiments in human cell cultures reveal a mechanism through which scientists can regulate defective tau protein levels. Now, scientists have identified a molecule that

Large-scale research suggests that drinking alcohol in older age may lower mortality risk. However, the scientists are cautious about potential biases in their own research and say that more research is necessary. Does moderate drinking in older age have any health benefits? A new study investigates. The debate around the potential health benefits of alcohol

A recent study concludes that social interaction might be more than just a pleasant pastime; it might help doctors predict an individual’s risk of cognitive decline and, perhaps, dementia. How does social interaction influence cognitive decline? Cognitive decline refers to a general reduction in mental abilities over time. It affects many people as they age

Researchers have designed a brain aging model to investigate the factors that contribute to cognitive decline, borrowing principles from precision medicine. How can we tackle cognitive decline? Cognitive decline affects a person’s ability to focus, remember, and make decisions. Its severity can range from mild to severe, and it may lead to dementia, in the

A common class of drugs that doctors prescribe for a number of conditions — from bladder problems to Parkinson’s disease and depression — may increase a person’s risk of dementia, a large new study concludes. Some common drugs may increase dementia risk. New research by scientists from the University of Nottingham in the United Kingdom

Researchers have found that nilvadipine, a drug that doctors regularly use to treat hypertension, may help people with Alzheimer’s disease by increasing blood flow to the brain. New research suggests that a high blood pressure drug may slow down the progression of Alzheimer’s disease. Alzheimer’s disease is the most common form of dementia. This progressive

In this Spotlight, we introduce the glymphatic system: the brain’s dedicated waste clearance system. Now implicated in various conditions, it is high time that we became acquainted. Astroglia (illustrated above) play a pivotal role in the brain’s trash collection service. Many of us are relatively familiar with the lymphatic system; it performs a number of

A large study concludes that atrial fibrillation does, indeed, raise the risk of dementia even in people who did not have a stroke and that anticoagulants may reduce this risk. An irregular heartbeat may be a sign of A-fib, which may, in turn, raise dementia risk. Atrial fibrillation (A-fib) is a condition in which the

Researchers reveal a marker and new testing tool of frontotemporal dementia that may help distinguish this condition from Alzheimer’s disease. ‘Moral emotions’ are ones that prompt us to do good and contribute to pro-social behavior and cooperation. Frontotemporal dementia (FTD) is a less common form of dementia than Alzheimer’s. Sometimes called Pick’s disease or frontal

New research in mice uncovers a previously unknown “pathway toward healthy aging.” A circulating protein from the blood of young mice led to health improvements and visible signs of rejuvenation when researchers gave it to aging mice. Scientists have found an enzyme that might have antiaging properties in humans as it does in mice. As

Older adults with insufficient vitamin K are likely to be at higher risk for mobility disability, according to new research. New research shows that low levels of vitamin K may restrict mobility in older adults. Dietary sources of vitamin K include kale, spinach, broccoli, and other leafy greens. Some dairy foods also contain vitamin K.

For many years, specialists believed that people who studied more and kept their brains more active had lower dementia risk. Some recent studies have contradicted this idea. So how is education linked to the evolution of Alzheimer’s disease, if at all? Another study suggests that there is no link between a person’s level of education

There are two major stumbling blocks to developing effective drugs for Alzheimer’s, Parkinson’s, and other diseases that destroy the brain. The first is overcoming the blood-brain barrier, and the second is delivering the drug to a precise location and ensuring that it does not spread to the rest of the brain. New research finds a

Millions of people die prematurely each year due to noncommunicable diseases, some of the most common of which are cardiovascular diseases. New research from Harvard suggests that three tried and tested interventions could prevent many of those deaths if implemented through global policies. Three global interventions could prevent millions of deaths over the next couple

Many factors can cause eyebrow hair loss, including hormonal imbalances, diet, and some skin conditions. Determining the cause of eyebrow hair loss can help a person find the best treatment. Eyebrow hair loss, the medical name for which is eyebrow hypotrichosis, or eyebrow madarosis, can cause a person to notice thinning hair or missing patches

Targeting the gut microbiome — the communities of bacteria and other microorganisms that inhabit the gastrointestinal tract — could be a way to treat a range of age-related conditions. Scientists made this conclusion after investigating the effect of transplanting fecal samples from young to aged mice. Jump-starting the gut bacteria may help people age more

A large new study has found a link between taking various kinds of blood pressure-lowering drugs and a lower risk of dementia among older adults, adding to the discussion around the link between cognitive decline and high blood pressure. People who take blood pressure-lowering medication may have a lower risk of dementia. Dementia is an
