With a growing number of states legalizing recreational or medical marijuana, more women are using the drug during pregnancy, in part due to its reported ability to relieve morning sickness. A new study, conducted in rats, sheds light on how cannabis exposure affects the brain of a developing fetus.
Researchers are reporting early success with a new tool to help people with Parkinson's disease improve their balance and potentially decrease falls with high-tech help: virtual reality. After practicing with a virtual reality system for six weeks, people with Parkinson's disease demonstrated improved obstacle negotiation and balance along with more confidence navigating around obstacles in their path.
A study led by a team from the University of Barcelona identified greater cortical thickness in the frontal lobe in a group of old people with high levels of education. The study of the molecular architecture revealed these areas feature a relative overexpression of gene families involved in the synaptic transmission and the activation of the immune response. Results may explain how high levels of education are associated with the preserved cognitive function in the elderly.
A recent study found that nearly 18 percent of patients diagnosed with multiple sclerosis before being referred to two major Los Angeles medical centers for treatment actually had been misdiagnosed with the autoimmune disease. The investigators found that many patients who came to the medical centers with a previous diagnosis of MS did not fulfill the criteria for that diagnosis, and spent an average of four years being treated for MS before receiving a correct diagnosis.
A protein implicated in the development of migraine symptoms caused pain responses in female rodents, but not in males, when introduced into the meninges, potentially helping to explain why migraine is three times more common in women than men.
Young children who live close to a major roadway are twice as likely to score lower on tests of communications skills, compared to those who live farther away from a major roadway, according to an analysis by researchers at the National Institutes of Health and the University of California, Merced.
Prefrontal brain regions linked to higher educational attainment are characterized by increased expression of genes involved in neurotransmission and immunity, finds a study of healthy older adults published in JNeurosci. The identified genes and molecular pathways could provide insight into factors that help keep the brain sharp in old age.
Performance-enhancing steroid use could increase the risk of cocaine use and addiction in teens, according to a new rodent study. The combination of these drugs could also impair fertility in young women. The research will be presented today at the American Physiological Society's (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla.
New research in mice suggests that a shared circuit in the brain could be one reason why heavy drinking and high-fat 'junk food' cravings go hand in hand. The findings will be presented today at the American Physiological Society's (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla.
Consuming garlic helps counteract age-related changes in gut bacteria associated with memory problems, according to a new study conducted with mice. The benefit comes from allyl sulfide, a compound in garlic known for its health benefits.
