Published Bullied teens' brains show chemical change associated with psychosis (via sciencedaily.com) Original source
Researchers have found that adolescents being bullied by their peers are at greater risk of the early stages of psychotic episodes and in turn experience lower levels of a key neurotransmitter in a part of the brain involved in regulating emotions. The finding suggests that this neurotransmitter may be a potential target for pharmaceutical interventions aimed at reducing the risk of psychotic disorders.
Published Active components of ginkgo biloba may improve early cognitive recovery after stroke (via sciencedaily.com) Original source
Adults treated with 14 days of intravenous injections of ginkgo diterpene lactone meglumine (GDLM) -- a combination of biologically active components of ginkgo biloba -- after an ischemic (clot-caused) stroke had better cognitive recovery at 14 days and 90 days.
Published Firing nerve fibers in the brain are supplied with energy on demand (via sciencedaily.com) Original source
To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical signals of active nerve fibers and provide them with energy on demand, as researchers have discovered. If this process, regulated by potassium, is disabled in mice, the nerve fibers are severely damaged as the animals age -- resembling the defects of neurodegenerative diseases.
Published Vigilant monitoring is needed to manage cardiac risks in patients using antipsychotics, doctors say (via sciencedaily.com) Original source
The use of the antipsychotic drugs quetiapine and haloperidol is associated with an increased risk of ventricular arrhythmias and sudden cardiac death (SCD) caused by drug-induced QT prolongation, reports a new study. Caution is advised to manage cardiac risks in patients prescribed these medications, the authors of the study and an accompanying editorial say.
Published Study reveals function of little-understood synapse in the brain (via sciencedaily.com) Original source
New research for the first time reveals the function of a little-understood junction between cells in the brain that could have important treatment implications for conditions ranging from multiple sclerosis to Alzheimer's disease, to a type of brain cancer known as glioma. Neuroscientists focused on the synapse connecting neurons to a non-neuronal cell, known as oligodendrocyte precursor cells. OPCs can differentiate into oligodendrocytes, which produce a sheath around nerves known as myelin. Myelin is the protective sheath covering each nerve cell's axon -- the threadlike portion of a cell that transmits electrical signals between cells.
Published Clinical predictive models created by AI are accurate but study-specific, researchers find (via sciencedaily.com) Original source
Scientists were able to show that statistical models created by artificial intelligence (AI) predict very accurately whether a medication responds in people with schizophrenia. However, the models are highly context-dependent and cannot be generalized.
Published Quest for personalized medicine hits a snag (via sciencedaily.com) Original source
The quest for personalized medicine, a medical approach in which practitioners use a patient's unique genetic profile to tailor individual treatment, has emerged as a critical goal in the health care sector. But a new study shows that the mathematical models currently available to predict treatments have limited effectiveness.
Published A more eco-friendly facial sheet mask that moisturizes, even though it's packaged dry (via sciencedaily.com) Original source
Starting a new year, many people pledge to enact self-care routines that improve their appearance. And facial sheet masks soaked in skin care ingredients provide an easy way to do this. However, these wet masks and their waterproof packaging often contain plastics and preservatives. Now, a study reports a dry-packaged hydrating facial mask that is made of biobased and sustainable materials.
Published Unravelling the association between neonatal proteins and adult health (via sciencedaily.com) Original source
Scientists studied two complement components that are important parts of the immune system and are linked to schizophrenia and autoimmune disorders. They studied the link between two protein concentrations -- C3 and C4 -- in over 68,000 newborn babies and the risk of developing six mental disorders later in life.
Published Yoga nidra might be a path to better sleep and improved memory (via sciencedaily.com) Original source
Practicing yoga nidra -- a kind of mindfulness training -- might improve sleep, cognition, learning, and memory, even in novices, according to a pilot study. After a two-week intervention with a cohort of novice practitioners, the researchers found that the percentage of delta-waves in deep sleep increased and that all tested cognitive abilities improved.
Published Cheap medicines prevented migraine as well as expensive ones (via sciencedaily.com) Original source
A new study sheds light on what works best to prevent migraine attacks, and surprisingly, cheaper medicines worked as well as the expensive ones.
Published For epilepsy, yoga may be good for your mind (via sciencedaily.com) Original source
For people with epilepsy, doing yoga may help reduce feelings of stigma about the disease along with reducing seizure frequency and anxiety, according to new research.
Published An unexpected link between 2 schizophrenia risk proteins (via sciencedaily.com) Original source
The discovery of a physical interaction between two proteins in brain cells that can be traced in mice to control of movement, anxiety and memory could one day open the door to development of new schizophrenia treatment strategies, researchers say.
Published New clues to early development of schizophrenia (via sciencedaily.com) Original source
Schizophrenia is a severe neuropsychiatric disease that remains poorly understood and treated. Schizophrenia onset is typically in adolescence or early adulthood, but its underlying causes are thought to involve neurodevelopmental abnormalities. Because human prenatal and postnatal brain tissue is exceedingly difficult to procure and therefore study, researchers have had limited opportunities to identify early disease mechanisms, especially during the critical prenatal period. Now, a pair of studies use new technology to study schizophrenia in models of early human brain development.
Published Heated yoga may reduce depression symptoms, according to recent clinical trial (via sciencedaily.com) Original source
In a randomized controlled clinical trial of adults with moderate-to-severe depression, those who participated in heated yoga sessions experienced significantly greater reductions in depressive symptoms compared with a control group.
Published Brain connectivity is disrupted in schizophrenia (via sciencedaily.com) Original source
Schizophrenia, a neurodevelopmental disorder that features psychosis among its symptoms, is thought to arise from disorganization in brain connectivity and functional integration. Now, a new study finds differences in functional brain connectivity in people with and without psychosis and schizophrenia that could help researchers understand the neural underpinnings of this disease.
Published Omega watch: Researchers develop new blood test for measuring levels of critical omega-3 fatty acids (via sciencedaily.com) Original source
Researchers have discovered a convenient new way to track levels of omega-3 fatty acids in the bloodstream, making it much easier to access information that is critical to cardiovascular and cognitive health, but which has previously been challenging to gather. While the human body can generate most of the fats it needs, it cannot produce adequate levels of omega-3 fatty acids and must obtain them from dietary sources.
Published AI language models could help diagnose schizophrenia (via sciencedaily.com) Original source
Scientists have developed new tools, based on AI language models, that can characterize subtle signatures in the speech of patients diagnosed with schizophrenia.
Published Scientists take next big step in understanding genetics of schizophrenia (via sciencedaily.com) Original source
Scientists are figuring out which of the 5,000 variants associated with schizophrenia have an actual causal effect in the development of the condition that affects millions of people worldwide.
Published Socioeconomic status may be an uneven predictor of heart health (via sciencedaily.com) Original source
The benefits of four measures of socioeconomic status (education, income, employment status and health insurance) on ideal heart health were greater for non-Hispanic white adults compared to Black, Hispanic and Asian adults in the U.S.
