What Are the Links Between COVID-19, Brain Harm, and Dementia Risk? — MedicineNet Health News
Latest Alzheimer’s News MONDAY, Nov. 22, 2021 Headaches, brain fog and that peculiar inability to smell or taste things. By now, most people know these symptoms as a few of the hallmarks of COVID-19. Researchers say they are a clear indication the virus impacts neurological functions. But what that impact means to long-term […]
As we develop, the brain connects lessons learned differently
A new study of brain activity patterns in people doing a memory task finds that the way we make inferences — finding hidden connections between different experiences — changes dramatically as we age. The study’s findings might one day lead to personalized learning strategies based on a person’s cognitive and brain development. The researchers found […]
Blood plasma protein fibrinogen interacts directly with nerve cells to cause brain inflammation
Neuroinflammatory diseases, including Alzheimer’s disease and traumatic brain injury, have been linked to deposits of a tough protein known as fibrin, derived from the blood clotting factor fibrinogen. These mesh-like fibrin deposits occur outside blood vessels in the brain, contributing to the death of certain central nervous system cells (neurons) that eventually leads to impaired […]
Researchers investigate role of gene associated with Alzheimer’s disease in brain’s immune cells
When immune cells move throughout the brain, they act as the first line of defense against viruses, toxic materials and damaged neurons, rushing over to clear out them. Researchers at Indiana University School of Medicine have been investigating how these immune cells in the brain — microglia — relate to a gene mutation recently found […]
Brain reveals the risk for developing obesity
Obesity risk factors of family background are associated with changes in the brain function, finds a study conducted at the Finnish Turku PET Centre. The results show that the function of neural networks regulating satiety and appetite is altered already before a person develops obesity. Obesity is a globally increasing health problem, and new interventions […]
Insomnia may be a risk factor for highly fatal brain aneurysm rupture
Insomnia may be a potential risk factor for a brain bleed from a ruptured aneurysm along with more well known risk factors of smoking and high blood pressure, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association. More than 3% of […]
Brain-circuit discovery may help explain sex differences in binge drinking
A brain circuit that works as a “brake” on binge alcohol drinking may help explain male-female differences invulnerability to alcohol use disorders, according to a preclinical study led by scientists at Weill Cornell Medicine. In the study, which appeared August 23 in Nature Communications, the researchers examined a brain region in mice called the bed […]
Directly into the brain: A 3D multifunctional and flexible neural interface: Novel design of brain chip implant allows for measuring neuronal activity while simultaneously delivering drugs to the implant site
Being able to measure the electrical activity of the brain has helped us gain a much better understanding of the brain’s processes, functions, and diseases over the past decades. So far, much of this activity has been measured via electrodes placed on the scalp (through electroencephalography (EEG)); however, being able to acquire signals directly from […]
Zebrafish anticipate the future to avoid virtual danger
Scientists from the RIKEN Center for Brain Science (CBS) and collaborators in Japan have discovered particular neurons in the brain that monitor whether predictions made by fish actually come true. By making use of a new virtual reality-outfitted aquarium where brain imaging of zebrafish can be done as they learn and navigate through virtual reality […]
Novel small molecule potently attenuates neuroinflammation in brain and glial cells
Neuroinflammation can worsen outcomes in stroke, traumatic brain injury or spinal cord injury, as well as accelerate neurodegenerative diseases like ALS, Parkinson’s or Alzheimer’s. This suggests that limiting neuroinflammation may represent a promising new approach to treat neurological diseases and neuropathic pain that are driven by neuroinflammation. In a preclinical study published in the journal […]
