Evidence indicates that following a Mediterranean-style diet, rich in fruit, vegetables, nuts, and cereals, can bring many health benefits, including protection against cardiovascular and metabolic problems. Now, a study also presents a link between this diet and a lower risk of depression later in life. New research finds a link between Mediterranean-style diets and a

New research identifies changes in the neurochemistry and anatomy of the brain that occur decades before people experience any symptoms of Alzheimer’s disease. Brain changes may occur decades before people experience Alzheimer’s symptoms, accumulating evidence suggests. The fact that more than 35 million people are currently living with Alzheimer’s disease has led some experts to

Research in mice now shows that a specific cell death mechanism can lead to rheumatoid arthritis. Stopping this mechanism could help prevent this condition from developing, the authors argue. Researchers uncover a key cellular mechanism involved in RA that has potential therapeutic implications. Rheumatoid arthritis (RA) is a chronic autoimmune condition characterized mainly by pain

Researchers have previously shown that a type of light therapy could potentially reduce toxic proteins that build up in the brain in Alzheimer’s disease. Now, the same team has identified what happens at cell level to achieve this result. A recent study asked why flickering light might help fight Alzheimer’s. In 2016, scientists at Massachusetts

An international working group of experts has agreed on guidelines to help increase scientific and public awareness about a brain condition that mimics Alzheimer’s disease. The condition is not new but has come to light in recent research and clinical trials. Researchers have identified a misfolded protein in the brain that may be ‘a possible

A prescription drug already in use for the treatment of high blood pressure could be effective against conditions such as Parkinson’s, Alzheimer’s, and Huntington’s, in which toxic proteins build up in brain cells. Scientists could repurpose felodipine to prevent Parkinson’s disease. Scientists at the University of Cambridge in the United Kingdom and the Guangzhou Institutes

Increasing muscle strength is good, but increasing muscle power may be even better for enjoying a longer life, according to a recent study. Increased muscle power can improve longevity, new research suggests. Professor Claudio Gil Araújo, who is the director of research and education at Exercise Medicine Clinic — CLINIMEX in Rio de Janeiro, Brazil,

Alzheimer’s is a relentless disease in which toxic clusters of beta-amyloid protein collect in brain cells. Now, scientists have designed a synthetic peptide, or small protein, that can block beta-amyloid in its early and most harmful stages. New research may have found a way to stop Alzheimer’s-related brain damage in its early stages. The synthetic

The World Health Organization report that life expectancy has increased by 5 years, but data show inequalities in access to health services among countries. A new global report finds that people are living longer, despite disparities in healthcare access. The World Health Statistics series is an annual snapshot of global health compiled by the World

Memory can deteriorate naturally, due to age, and even when this process is not related to neurodegenerative conditions, such as Alzheimer’s, it can still affect a person’s quality of life. Now, researchers from Boston University in Massachusetts are exploring ways of fighting age-related memory decline. By resynchronizing brain waves, we could reverse some age-related memory

PET scans that can detect changes in the brain relating to Alzheimer’s disease could improve the diagnosis and medical care of people with dementia and similar symptoms. An innovative type of brain scan may improve care for people with Alzheimer’s disease, dementia, and other forms of cognitive impairment. Investigators came to this conclusion after analyzing

Oxidative stress is an imbalance of free radicals and antioxidants in the body, which can lead to cell and tissue damage. Oxidative stress occurs naturally and plays a role in the aging process. A large body of scientific evidence suggests that long-term oxidative stress contributes to the development in a range of chronic conditions. Such

Dementia — an umbrella term for various neurodegenerative conditions involving memory loss and other forms of cognitive impairment — is hard to treat because its causes remain unknown. Researchers, however, are making painstaking progress. A new approach to dementia research may bring us closer to a treatment, but unexpected challenges could halt this progress. Dr.

The blood-brain barrier is a protective layer that surrounds the brain. Its main function is to prevent potentially harmful agents from leaking into this organ. However, it can also stop certain therapeutic drugs from reaching their target. Using ultrasound in new ways could open the door to better treatments for conditions that affect the brain.

A randomized controlled study finds that a diet low in carbs can relieve pain for people who have knee osteoarthritis. Seniors with knee osteoarthritis may benefit from switching to a low-carb diet. Osteoarthritis is the most widespread form of arthritis among older adults in the United States. Knee osteoarthritis, in particular, affects about 10 percent

Researchers are finding new evidence that exercise — even low-intensity, casual physical activity — can boost brain health in the short- and long-term. Frequent but leisurely exercise can boost brain health. Evidence that exercise can benefit the brain and help maintain cognitive function — including memory — is accumulating. One study, for instance, suggests that

A parasitic fungus that infects caterpillars and various other insects may hold the key to better treatments for osteoarthritis, a condition characterized by pain and stiffness in a person’s joints. This, at least, is what new research from the United Kingdom suggests. A parasitic fungus could offer an improved treatment for osteoarthritis. Osteoarthritis is the
