Gene mutation enhances cognitive flexibility in mice, study suggests

Researchers at the National Institutes of Health have discovered in mice what they believe is the first known genetic mutation to improve cognitive flexibility—the ability to adapt to changing situations. The gene, KCND2, codes for a protein that regulates potassium channels, which control electrical signals that travel along neurons. The electrical signals stimulate chemical messengers

Parkinson’s symptoms improve with weekly regimens of both physical and cognitive exercises

Parkinson’s patients’ motor and non-motor symptoms were improved with a weekly exercise regimen that included physical and cognitive tasks, according to new research presented today (18 December) at The Physiological Society early career conference, Future Physiology 2019: Translating Cellular Mechanisms into Lifelong Health Strategies. Parkinson’s Disease is a chronic neurodegenerative disease that can lead to

Cognitive behavioral therapy effective for prenatal insomnia

(HealthDay)—Cognitive behavioral therapy is an effective nonpharmacologic treatment for insomnia during pregnancy, according to a study published online April 5 in Obstetrics & Gynecology. Rachel Manber, Ph.D., from Stanford University in California, and colleagues evaluated the effectiveness of cognitive behavioral therapy for insomnia during pregnancy among women (18 to 32 weeks of gestation) randomly assigned

Teen cannabis use is not without risk to cognitive development

Although studies have shown that alcohol and cannabis misuse are related to impaired cognition in youth, previous studies were not designed to understand this relationship and differentiate whether cannabis use was causal or consequential to cognitive impairment. A new study by researchers at CHU Sainte-Justine and Université de Montréal, published in the American Journal of

Link between depression and cognitive decline explored

Depression can affect anyone at any stage of their life. According to the Centers for Disease Control and Prevention (CDC), about 1 in 6 people in the United States will experience depression at some point in their life. Scientists do not know the exact cause of depression, but many believe it is a combination of

Acupuncture and cognitive behavioral therapy for treating insomnia in cancer survivors

A Patient-Centered Outcomes Research Institute (PCORI)-supported randomized clinical trial of cancer survivors showed that eight weeks of either acupuncture or cognitive behavioral therapy for insomnia (CBT-I) decreased the severity of insomnia among cancer survivors, though improvements were greatest among patients receiving cognitive behavioral therapy. The study will be presented at the upcoming 2018 ASCO Annual

Brain size mediates the association between height and cognitive ability

Several studies have found that height and general cognitive ability, or intelligence, are positively associated. A recent study reveals a biological factor underlying this relationship: the size of the cerebral cortex. Reports from several studies have identified a link between height and general cognitive ability, or intelligence, but the mechanisms underlying this association are not

Looking for links between diet, gut microbes and cognitive decline

Are abnormal intestinal microorganisms a risk factor for developing cognitive impairment? Researchers at Rush University Medical Center are trying to answer that question with a new, National Institute on Aging-funded study that will explore how the intestinal microbiota—the bacteria in the intestine—influence the progression of cognitive decline and the development of Alzheimer’s disease.
