The damage done to the brain by physical trauma doesn’t end with the initial impact. It triggers a series of harmful molecular and cellular events that lead to a damaging secondary injury. But scientists are learning that the brain’s cannabinoid system is a powerful tool for handling TBIs, which means cannabis could become a promising
Alzheimer’s disease (AD) is a debilitating neurodegenerative disease characterized by the accumulation of amyloid-β and tau hyperphosphorylation as well as neuroinflammation and oxidative stress. Current AD treatments do not stop or reverse the disease progression. It is unlikely that any drug acting on a single pathway or target will mitigate the complex pathoetiological cascade leading to AD. Therefore,
Published in the American Journal of Psychiatry, a King’s College London clinical trial involving the cannabis compound CBD has shown it may be beneficial in treating psychosis in schizophrenia. While cannabis can pose a risk to people with schizophrenia, this is primarily due to the effects THC, the psychoactive component that can induce paranoia, anxiety and trigger psychosis.
A good night’s sleep and a higher IQ could be achieved by eating fish at least once per week — for children, at least. UPenn researchers analyzed the IQs, fish-eating habits and sleeping patterns of 541 Chinese children aged 9–11 years. They found children who ate fish weekly scored 4.8 points higher on IQ tests
New, unpublished research, presented in November at the annual Society for Neuroscience conference suggests female soccer players experience greater brain damage from heading the ball than men do. The injury occurs in white matter tracts — the long, branch-like nerve fibers, or axons, that extend from neurons, crisscross the brain and connect different regions. The research
Living with TBI is full of challenges for daily living. Here are some problems experienced by an engineer and what he did about them: Physically—I dropped tools and parts out of my left hand because it got weak easily. Mentally—my working memory had completely malfunctioned and I had a short attention span. Visually—I saw everything in double
The link between concussions and brain injury might be a hot topic in the NFL, but at the high school level? Apparently not so much. Overall, only about a third of high school athletes, their coaches and parents know that a concussion is a brain injury, according to a new study by Mayo Clinic researchers.
University of Maryland School of Medicine (UMSOM) researchers have found a two-way link between traumatic brain injury (TBI) and intestinal changes. These interactions may contribute to increased infections in these patients, and may also worsen chronic brain damage. This is the first study to find that TBI in mice can trigger delayed, long-term changes in the
The US DEA continues to stand by a decades-old assertion that cannabisand certain of its derivatives are as dangerous as heroin, in spite of a wealth of increasing evidence revealing that the opposite is true. In a preliminary report released by the World Health Organization (WHO) last month, a non-psychoactive substance in cannabis, cannabidiol, which the US Drug
