Neuroscientists should help to develop compelling digital games that boost brain function and improve well-being, say two professors specializing in the field in a commentary article published in the science journal Nature.
For chronic pain sufferers, such as people who develop back pain after a car accident, avoiding the harmful effects of stress may be key to managing their condition. This is particularly important for people with a smaller-than-average hippocampus, as these individuals seem to be particularly vulnerable to stress.
A novel way to image the brain’s glymphatic pathway may provide the basis for a new strategy to evaluate Alzheimer's disease susceptibility, according to a research paper published in The Journal of Clinical Investigation.
The American Academy of Neurology (AAN) is releasing a list of five tests, procedures, and treatments that doctors and their patients should question as part of today’s announcement regarding the “Choosing Wisely” campaign by the American Board of Internal Medicine (ABIM) Foundation. The list is published in the February 21, 2013, online issue of Neurology, the medical journal of the American Academy of Neurology. Sixteen other medical societies are also releasing their lists.
In the weeks, months and years after a severe head injury, patients often experience epileptic seizures that are difficult to control. A new study in rats suggests that gently cooling the brain after injury may prevent these seizures.
Triglyceride lipid emulsions rich in an omega-3 fatty acid injected within a few hours of an ischemic stroke can decrease the amount of damaged brain tissue by 50 percent or more in mice, reports a new study by researchers at Columbia University Medical Center. The results suggest that the emulsions may be able to reduce some of the long-term neurological and behavioral problems seen in human survivors of neonatal stroke and possibly of adult stroke, as well.
Contrary to other research, a new study found that the total level of antioxidants in people’s diets is not related to their risk of developing stroke or dementia. The study is published in the February 20, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Antioxidants such as lycopene, beta-carotene and vitamins C and E are found in many foods.
A team of researchers at UC San Francisco has uncovered the neurological basis of speech motor control, the complex coordinated activity of tiny brain regions that controls our lips, jaw, tongue and larynx as we speak.
New findings by Columbia researchers suggest that along with amyloid deposits, white matter hyperintensities (WMHs) may be a second necessary factor for the development of Alzheimer’s disease.
In a pair of new papers, researchers at the University of California, San Diego School of Medicine and the Royal Netherlands Academy of Arts and Sciences upend a long-held view about the basic functioning of a key receptor molecule involved in signaling between neurons, and describe how a compound linked to Alzheimer’s disease impacts that receptor and weakens synaptic connections between brain cells.
A new study led by an international team of biologists has identified some of the brain chemicals that allow seals to sleep with half of their brain at a time.
A new Columbia Engineering study finds that the infant brain does not control its blood flow the same way as the adult brain, that the control of brain blood flow develops with age. These findings could change the way researchers study brain development in infants and children.
One of the most challenging issues in stroke care involves the use of clot-busting drugs such as tPA. In Expert Review of Neurotherapeutics, stroke specialists offer guidance on commonly asked questions about the use of these drugs.
Newswise invites press release submissions from new and current members for inclusion in our Theme Wires on a variety of topics, including; Cancer Research, Environment and Climate Change, Nutrition, and Mental Health. Each wire is also open for sponsorships to promote your organization’s campaign, product, service, or news.
New Mayo Clinic research suggests that blood may hold clues to whether post-menopausal women may be at an increased risk for areas of brain damage that can lead to memory problems and possibly increased risk of stroke. The study shows that blood’s tendency to clot may contribute to areas of brain damage called white matter hyperintensities. The findings are published in the Feb. 13 online issue of Neurology, the medical journal of the American Academy of Neurology.
For many patients with difficult-to-treat neuropathic pain, deep brain stimulation (DBS) can lead to long-term improvement in pain scores and other outcomes, according to a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Two patients freed from severe to disabling effects of dystonia through deep brain stimulation therapy continued to have symptom relief for months after their devices accidentally were fully or partly turned off, according to a report published online Feb. 11 in the journal Movement Disorders.
Researchers at Mayo Clinic have discovered an abnormal protein that accumulates in the brains of many patients affected with two common neurodegenerative disorders — amyotrophic lateral sclerosis, also known as ALS or Lou Gehrig’s disease, and frontotemporal dementia.
Strokes that occur during or shortly after surgery can be devastating, resulting in longer hospital stays and increased risks of death or long-term disability, but prompt identification and treatment can improve neurologic outcomes.
Researchers at the University of California, San Diego School of Medicine say overexpression of a protein called alpha-synuclein appears to disrupt vital recycling processes in neurons, starting with the terminal extensions of neurons and working its way back to the cells’ center, with the potential consequence of progressive degeneration and eventual cell death.
