New research finds that a 6-month regimen of aerobic exercise can reverse symptoms of mild cognitive impairment in older adults. Just 6 months of exercise that raises the heart rate can reverse signs of age-related cognitive impairment. Mild cognitive impairment (MCI) is characterized by a mild loss of cognitive abilities, such as memory and reasoning

Alzheimer’s disease is a form of neurocognitive decline that affects millions across the world. The exact cause is unclear, but new research is uncovering the mechanisms that allow Alzheimer’s to become established in the brain. Which brain cells are the most vulnerable to Alzheimer’s? In Alzheimer’s disease, as in other forms of dementia, a defining

Women tend to live longer than men, a difference that seems to apply to female versus male individuals across the animal kingdom. Why is this the case? What gives women their longevity? Genetically, most women have two X chromosomes, and most men have one X and one Y chromosome. X chromosomes contain hundreds of protein-encoding

A widely held belief has it that the more we use our brains, the less likely it is that we will experience mental decline as we age, but to what extent is this notion true? A new study tests whether flexing your brain with problem-solving tasks can help prevent age-related mental decline. As we get

Doctors may find it hard to diagnose Alzheimer’s disease before the obvious symptoms set in, and many of the current tests for it are expensive and complicated. However, researchers recently devised a blood test that could accurately detect this condition. Recent research aimed to develop an accurate blood test to diagnose Alzheimer’s. According to the

New research looks to brain lipids to identify a new therapeutic target for Parkinson’s disease. Researchers have identified a new therapeutic target to disrupt the formation of toxic plaques in the brain. Parkinson’s disease is a neurodegenerative condition that affects about half a million people in the United States, according to the National Institutes of

For the first time, researchers have identified two clusters of genes that appear to generate the neurological hallmarks of dementia. The discovery provides a new path toward drug discovery. Understanding the genetic mechanisms behind Alzheimer’s moves us ever closer to an effective treatment. Dementia is a growing concern throughout the Western world and beyond. According

A recent article raises important questions about the prevalence of firearms in the aging population of the United States. The authors argue that there is a vital need to discuss the relationship between dementia and guns. A recent article investigates the issue of gun ownership in an aging population. Gun ownership is a controversial topic,

In a new study involving people over 70 who have exercised regularly for years, scientists discovered that the participants’ hearts, lungs, and muscles were in equivalent shape to those of people in their 40s. Regular exercise could help keep the body young, new research shows. Researchers from the Human Performance Laboratory at Ball State University

Endurance training, resistance training, or high-intensity interval training — what type of physical exercise will help your body to stay youthful for longer? A new study aims to answer that question. What type of training should you embrace for healthy aging? New research investigates. One key factor in cellular health is telomeres, the “safety caps”

Dementia refers to a series of neurodegenerative diseases, such as Alzheimer’s, where a person’s memory and other cognitive abilities decline. A recent study may have found a new risk factor that might predispose people to dementia: lung disease. To limit the risk of dementia, people may also want to look after the health of their

Hyperpigmentation is the name that healthcare professionals give to patches of skin that become darker than surrounding areas of skin. Types of hyperpigmentation include age spots, melasma, and post-inflammatory hyperpigmentation. Each of these has different cause and a range of treatments and products, including creams and cosmetic procedures. We discuss these below. What is hyperpigmentation?

Cancer treatments can work, but the same factors that help them eradicate tumors may also accelerate aging processes in the body — especially the brain. New research explores. Breast cancer treatments leave their mark on the brain years after completion, a new study suggests. Previously on Medical News Today, we covered a study explaining that

New research finds that an HIV enzyme plays a crucial role in driving Alzheimer’s-related brain pathology by altering the APP gene. The findings warrant “immediate clinical evaluation of HIV antiretroviral therapies in people with Alzheimer’s disease,” say the authors of the study. The revelations of a recent study suggest that HIV drugs might successfully treat

New research, published in the journal Cell Reports, suggests that a low-protein, high-carb diet may be an easier alternative to calorie restriction for people looking to preserve brain health and prevent cognitive decline. Components of traditional low-protein, high-carb diets include lean fish and sweet potatoes. As the world’s population ages, protecting against cognitive decline is

The largest genetic study of Alzheimer’s disease to date finds that a “handful of gene variants” increases some people’s risk of both dementia and cardiovascular disease. The findings imply that, in principle, we may be able to repurpose some cardiovascular drugs to prevent or treat Alzheimer’s. The findings of a new study raise the question:

Building on decades of research, a new paper brings us one step closer to a vaccine that targets the neurological hallmarks of Alzheimer’s disease. Prevention may soon be possible. Scientists inch closer to finding a way to prevent Alzheimer’s disease. Alzheimer’s disease, the most common form of dementia, is a degenerative neurological disease. Memory issues

New research finds that our response to even minor daily stressors, such as getting stuck in traffic or queuing for too long at the supermarket, can affect how healthy our brain is, particularly into old age. Our emotional response to a daily stressful situation, such as being stuck in traffic, may affect our brain health,

A long-held belief has it that some people have “better genes” than others, which predisposes them to living longer lives. A large new study, however, questions the accuracy of this idea. Do genes really predict lifespan? Scientists from Calico Life Sciences, a research and development company — in collaboration with colleagues from Ancestry, an online

An artificial intelligence tool taught to analyze brain scans can accurately predict Alzheimer’s disease several years before a final diagnosis. Researchers used PET scans to train a deep learning algorithm to predict signs of Alzheimer’s. The team responsible suggests that, after further validation, the tool could greatly assist the early detection of Alzheimer’s, giving treatments
