Brains of young people exposed to dirty air show signs consistent with Alzheimer’s and Parkinson’s
It’s no secret that air pollution can damage the lungs and the heart. But new research suggests that exposure to polluted air can trigger neurodegeneration as well. In a study published in the journal Environmental Research, an international team of researchers described how they found tiny air pollution particles lodged in the brain stems of […]

How does the glymphatic system get rid of “trash” in your brain?
In a major breakthrough, researchers from the University of Rochester Medical Center (URMC) discovered the primary cleansing system responsible for keeping the brain free from toxins and harmful substances. Published in Science Translational Medicine, their findings revealed that this clearing system, dubbed the “glymphatic system,” is most active during sleep. The brain can cleanse itself in a […]

Study: Aerobic exercise is key to lowering the risk of dementia among the elderly
Regular exercise among older adults is critical to good health. It keeps aging bodies from becoming stiff and susceptible to chronic conditions, such as heart disease, diabetes and arthritis. But scientists find that maintaining optimum fitness in old age might also protect against another age-related problem: brain decline. In a major breakthrough, Rong Zhang, an expert […]

Keep moving for better cognitive function: Regular exercise delays brain deterioration in those at risk for Alzheimer’s
Exercising is one of the best things that older adults can do to reduce their risk of dementia, according to the findings of a recent randomized controlled trial (RCT). In a major breakthrough, Rong Zhang, a neurologist at the University of Texas Southwestern (UTSW) Medical Center, and his colleagues found that regular aerobic exercise training can […]

Study: Over-the-counter drugs can increase your risk of developing dementia
Anticholinergic drugs are prescribed by doctors to treat a variety of conditions. These range from inflammatory lung diseases like chronic obstructive pulmonary disease (COPD) to gastrointestinal disorders like diarrhea and brain disorders like Parkinson’s disease. Anticholinergic drugs work by blocking a chemical called acetylcholine, which serves as the chief neurotransmitter of the parasympathetic nervous system. […]

Why do sufferers of Alzheimer’s nap so much? Study suggests the disease kills the cells needed to stay awake
A study published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association found that in people with Alzheimer’s, tau proteins promote the degeneration of brain regions responsible for keeping people awake. This explains why excessive daytime napping is common among people with the disease and suggests that it could be an early sign of Alzheimer’s. Previous studies have explored […]

Immune cells ATTACK the aging brain and release a substance that hinders new nerve cell production, report scientists
One of the defining features of the brain that sets it apart from all other organs of the human body (except muscles) is that it is made up of cells that cannot regenerate. The nerve cells in the brain called neurons are terminally differentiated, meaning that, unlike skin cells or blood cells, they cannot reproduce. So […]

Microglia protect the central nervous system from inflammation and could hold the key to treating retina disease
Microglia help protect the central nervous system from disease-causing pathogens and issues. Recent research has revealed that these cells determine whether or not other immune cells might enter the brain. Managing these gatekeeper cells might offer a way to control the risk of inflammation that damage the retina. Researchers at the Massachusetts Eye and Ear (MEE) hospital discovered […]
