Newly identified neuromarker reveals clues about drug and food craving
Craving is known to be a key factor in substance use disorders and can increase the likelihood of future drug use or relapse. Yet its neural basis — or, how the brain gives rise to craving — is not well understood. In a new study, researchers from Yale, Dartmouth, and the French National Centre for […]
Long-Term Neurologic Problems Rise by 7% After SARS-CoV-2 Infection
Risk of movement disorders, memory problems, strokes, and seizures rose 1 year after acute SARS-CoV-2 infection, an analysis of millions of U.S. veterans’ records showed. Former COVID patients had a 42% increased risk of neurologic problems 12 months after testing positive (HR 1.42, 95% CI 1.38-1.47), reported Ziyad Al-Aly, MD, of Washington University in St. […]
Gene mutation discovered that causes language impairment, ADHD and myasthenia
Two studies have revealed that certain disorders of the CAPRIN1 gene have significant consequences for people. First, the research team showed that insufficient production of the protein CAPRIN1 in the brain can lead to developmental differences, including autism spectrum disorders, attention deficit hyperactivity disorder (ADHD), and language disorders. Furthermore, the scientists identified a specific mutation […]

No more binge eating: Signal pathway in the brain that controls food intake discovered
A group of researchers has developed an entirely novel approach to treating eating disorders. The scientists showed that a group of nerve cells in the hypothalamus (so-called AgRP, agouti-related peptide neurons) control the release of endogenous lysophospholipids, which in turn control the excitability of nerve cells in the cerebral cortex, which stimulates food intake. In […]

Learn about how mood disorders can affect cognitive function Studies have shown that people who have bipolar disorder are at an increased risk of dementia.

Medication treatment of pediatric psychiatric disorders reduces the later onset of substance use problems: Early and longer-lasting treatment reduces risk of substance use disorder most significantly
One half of psychiatric and substance use disorders start by the age of 18; three-quarters by age 24. While these are concerning statistics, a new study from Massachusetts General Hospital (MGH) finds that treating psychiatric disorders with psychotropic medications in children and adolescents does not increase the risk of developing substance use, misuse, or substance […]
