The vast majority of people who develop the rare neurological disease amyotrophic lateral sclerosis have one feature in common: toxic buildup of faulty TDP-43 protein in the affected nerve cells. One recent study tackled the toxic protein deposits that characterize 97 percent of ALS cases. Postmortem evidence suggests that 97 percent of people with amyotrophic

Although anecdotal sources and academic studies show that yoga can boost a person’s well-being, some may need to use caution. A new study suggests that certain yoga poses can lead to bone injuries in people with osteoporosis or osteopenia. Do some yoga poses worsen the symptoms of osteoporosis? In the United States, about 24.5 percent

A new study has revealed that a diet rich in protein and low in calories can help older adults with obesity lose more weight while maintaining muscle mass and improving bone density. Losing weight as an older adult presents some challenges. Older adults often lose bone density and muscle mass when they concentrate on shedding

Language and communication are as vital as food and water. We communicate to exchange information, build relationships, and create art. In this Spotlight feature, we look at how language manifests in the brain, and how it shapes our daily lives. In this feature, we will take a look at the importance of language to our

Dementia is a term that describes a variety of symptoms affecting a person’s cognitive functioning, including their ability to think, remember, and reason. It tends to get worse over time, so there are a few key early warning signs. Dementia occurs when nerve cells in a person’s brain stop working. Although it typically happens in

In Japan, many have long believed that a plant called ashitaba is important in supporting a person’s health and well-being. Now, researchers are suggesting that a compound in this plant boosts cellular health and may prolong youth. Practitioners of traditional medicine in Japan have long touted ashitaba’s health benefits. New research suggests that they may

Aging cells can become toxic to surrounding tissue, thus leading to numerous health problems. A class of drugs scientists call senolytics could help address these health issues, and improve symptoms. Can a new drug combination help fight off the ill effects of cellular aging? Senolytics are a class of drugs that target cells that have

New research examines the potential of stem cell therapy in the replacement of damaged neurons in Parkinson’s disease. The authors say that stem cells could “provide superior treatment, possibly using different types of cells to treat different symptoms” of Parkinson’s. Could stem cell therapy one day help treat Parkinson’s disease? Parkinson’s disease affects around half

New research has shown that impaired insulin signaling in the brain, often a feature of diabetes, may negatively impact cognition, mood, and metabolism — all of which are common aspects of Alzheimer’s disease. A new study examines the links between Alzheimer’s and diabetes. Although the conditions are seemingly independent of each other, earlier studies have

Memory loss does not only occur in neurodegenerative diseases, such as dementia. It also happens with age, or in relation to mental health problems, such as depression. Now, researchers have developed new compounds that could reverse this cognitive effect. Newly developed compounds may offer fresh hope for depression-related memory loss. Memory loss is not solely

As we age, we may experience a decline in our mental ability. A recent study has concluded that chronic inflammation in midlife might speed up this decline as we get older. Could influencing inflammation slow cognitive decline? The average age of the population of the United States is gradually increasing, so conditions of old age

New research in the Journal of Biological Chemistry breaks down the process through which tau tangles grow as long as they do. The findings may lead to new therapies that target the formation of tau aggregates in Alzheimer’s disease. Researchers knew that Alzheimer’s-related tau aggregates consisted of a small number of long tau fibrils. One

For years, many experts have assumed that spending more time in education protects against dementia. The latest study may overturn this long-held theory. A new study examines the links between education and dementia risk over time. It will have escaped no one’s attention that dementia is on the rise. The most common type of dementia

It is still unclear exactly what causes Alzheimer’s disease, which is a neurodegenerative condition chiefly characterized by memory loss and other forms of cognitive impairment. However, new research is uncovering more of the factors that contribute to its pathology. According to a new study, a blood protein leaked into the brain contributes to cognitive decline.

As interest in gut bacteria peaks, they are implicated in yet another condition. Researchers recently identified stark differences in levels of specific gut bacteria in people with dementia. A new study links changes in gut bacteria to dementia. Our bodies swarm with microscopic visitors. On our skin, in our mouths, deep in our lungs, and,

An article, published in JAMA Network this month, attacks what it refers to as pseudomedicine. In particular, the authors are concerned that individuals with dementia and their families are being targeted. Is fear of dementia being used to sell pseudomedicine? Dementia is becoming increasingly prevalent as the population of the United States ages. Currently, 5.7

Recent research adds to a growing body of knowledge that links hearing loss with cognitive decline, which is a hallmark of dementia and often precedes the disease. Research suggests a link between hearing loss and cognitive decline. After analyzing 8 years of data from a health study of more than 10,000 men, scientists at Brigham

In a new study, researchers have found that a bacterium largely responsible for gum disease also contributes to the development of Alzheimer’s disease. A bacterium involved in gum disease boosts Alzheimer’s toxicity. According to data from the National Institute of Dental and Craniofacial Research, 8.52 percent of adults between 20 and 64 years of age

Recent research suggests that doing even low-intensity physical activity allows older people to reduce their risk of dementia. Carrying out even basic activities in older age might help maintain brain health. Several factors can affect a person’s chance of developing dementia. Some of the factors, such as age and genetics, are unavoidable. Others, such as

Scientists have uncovered a mechanism through which a toxic brain protein that is a hallmark of Alzheimer’s disease can damage neurons, or brain cells. New research uncovers the mechanism that leads to the progressive loss of brain cells that characterizes Alzheimer’s disease. The team at the Grenoble Institute of Neurosciences in France that made the

New research suggests that stools from so-called “super donors” have such rich microbial diversity that using them for fecal transplants could cure conditions ranging from inflammatory bowel disease to Alzheimer’s and multiple sclerosis. Scientists have found that stool samples from ‘super donors’ hold the potential for curing a wide range of conditions. Recently, a growing
