Scientists have long known that getting enough sleep is important for brain health. Poor sleep has been linked to problems with memory, concentration, and mood. Over the past several years, researchers have also discovered that sleep may play an important role in the development of Alzheimer’s disease, the most common form of dementia. Now, a […] The post How Sleep and AQP4 Gene Variants May Shap…

For many older adults, glucosamine is a familiar name. The supplement is widely advertised as a way to support joint health and ease pain from arthritis. Because it is sold without a prescription and has been used by millions of people for years, many consumers view it as a safe and natural product. However, new […] The post Common Arthritis Supplement Linked to Faster Alzheimer’s Development app…

Walking is something most people do without thinking. The brain automatically coordinates movements of the legs, balance, and timing of each step. For people with Parkinson’s disease, however, walking can become one of the most difficult parts of daily life. Many patients shuffle their feet, lose balance, or suddenly freeze in place. Falls become more […] The post New Brain Device Could Help Peop…

For many years, doctors treated diabetes and dementia as two separate health problems. Diabetes was mainly seen as a disease that affects blood sugar and damages organs such as the heart, kidneys, and eyes. Dementia was viewed as a disorder of memory and thinking that happens in the brain. Today, scientists are finding that these […] The post Could Controlling Diabetes Help Prevent Dementia? appe…

When older adults undergo surgery, doctors often focus on complications such as infections, bleeding, or heart problems. Yet one of the most common complications affects the brain. Known as postoperative delirium, this condition can cause sudden confusion, disorientation, memory difficulties, and changes in behavior. Many families assume that delirium is temporary. In some cases, symptoms […] The…

Scientists are increasingly discovering that diabetes and dementia are closely connected. For many years, doctors thought of diabetes mainly as a disease that affects blood sugar, the heart, kidneys, and eyes. Dementia, on the other hand, was seen as a completely separate brain disorder. However, new studies are showing that the two conditions influence each […] The post 10 Surprising Ways Diabet…

Aeran and colleagues present research on targeted gene therapy vector engineering and pre-clinical testing of neuron-targeted AAV9-based constructs for STXBP1-related neurodevelopmental and epileptic encephalopathies. Candidate vectors designed to target specific neuronal types and detarget tissues associated with toxicity produced robust phenotypic reversal in Stxbp1 +/− mice and were well toler…

Nearly all Michiganders age 50 and over say it's very important to keep their brains healthy as they grow older, a new poll finds. But less than half (47%) of middle-aged and older Michiganders know that everyday actions can be very important for reducing their future risk of dementia.

Six months in, the capsules were clearly working. Spinal fluid drawn from older adults swallowing two grams of DHA a day showed the omega-3 piling up exactly where it was meant to go: inside the brain, ferried across from the bloodstream, lifting concentrations by roughly 17 per c New!

Alzheimer’s disease is one of the most feared illnesses of old age. It slowly damages memory, thinking, and the ability to manage everyday tasks. At first, a person may simply forget names or appointments. Over time, they may struggle to recognize loved ones, communicate clearly, or live independently. Because there is currently no cure for […] The post A Simple Eye Photo Could Spot Alzheimer’s R…

Many people think about exercise, healthy food, and mental activities when trying to protect their brains as they get older. However, scientists are beginning to discover that another everyday factor may also matter: sunlight and bright daytime exposure. Dementia affects memory, thinking, and behavior. As the condition progresses, it can interfere with a person’s ability […] The post This Simple …

Putting brain cells into a hibernation-like state via drugs that cool down core body temperature may help to preserve them following a stroke

Researchers investigated whether modulating a deep brain region called the zona incerta (ZI) could alleviate persistent tremor in patients with Parkinson’s disease.

Americans spend more than $1 billion annually on fish oil supplements, in part due to purported cognitive benefits from the omega-3 fatty acids they contain, essential nutrients that help form brain cell connections needed for cognition.

Most people rarely think about their sense of smell or taste. The smell of fresh coffee, the taste of a favorite family recipe, or the scent of flowers are such ordinary experiences that they often go unnoticed. It is only when these senses disappear that many people realize how important they are. A new study […] The post Losing Sense of Smell and Taste Can Be as Devastating as Parkinson’s and s…

A new Keck Medicine of USC study published suggests that increasing omega-3 levels via supplements has little effect on brain health despite showing evidence that the nutrients directly reach the brain.

Most people know the ketogenic diet as a popular way to lose weight. Celebrities, athletes, and people trying to improve their health have embraced the low-carbohydrate eating plan over the past decade. But scientists are increasingly discovering that the keto diet may have effects far beyond the bathroom scale. According to a new review published […] The post This Weight-Loss Diet May Also Fight…
