      Why Fidgeting Bothers Some People

      Misokinesia, affecting about one-third of individuals, is an aversion to repetitive bodily movements like fidgeting, causing emotional, cognitive, and physical distress. New research explores its impact on daily life, relationships, and mental well-being, revealing challenges such as intense distraction, rage, and social strain.

      Astrocytes Hold the Key to Stress Response Regulation

      Astrocytes, previously known for supporting nerve cells, have been identified as key regulators of stress responses in the lateral septum of the brain. Researchers demonstrated that astrocytes release adenosine to suppress nearby nerve activity when exposed to stress-inducing stimuli. This groundbreaking finding reveals that astrocytes interact dynamically with neurons to influence fear, anxiety, and social behaviors, varying based on the stress type and brain region.

      Mapping the Brain’s Response to Social Rejection

      A new study explores how the brain processes social acceptance and rejection, revealing how these experiences shape relationships and influence mental health. Using behavioral experiments and MRI imaging, researchers identified distinct brain regions activated during rewarding interactions and feelings of rejection. While acceptance triggers reward pathways, rejection activates areas tied to social value assessment, helping individuals gauge relational worth.

      Antipsychotics Worsen Behavior in Dementia

      A study of 500,000 Canadian nursing home residents found antipsychotic medications significantly worsened behaviors in patients, with nearly 68% experiencing increased issues. Antipsychotics are often prescribed "off-label" for dementia-related symptoms, despite serious side effects like tremors and cognitive decline. Researchers advocate for person-centered care, emphasizing non-drug therapies like music, art, and exercise to address behavioral issues.

      Gene Defect Linked Brain Size and Social Behavior in ASD, Schizophrenia

      A new study reveals how genetic deficits, particularly in the Tbx1 gene, are linked to reduced brain volume and altered social behavior, findings relevant to autism and schizophrenia. Researchers observed smaller amygdala volumes in Tbx1-deficient mice, a brain region key to emotional regulation and social behavior. These mice displayed less interest in social interaction, relying more on non-social cues like bedding preferences.

      Depression Genes in Women Linked to Higher Heart Disease Risk

      A new study analyzing genetic data from over 300,000 people revealed that women with a high genetic risk for depression also face a higher likelihood of developing heart disease, even without a depression diagnosis. This link was not observed in men, highlighting significant gender differences. Researchers emphasized the importance of addressing cardiovascular health in women, particularly those with depression, regardless of menopausal status.

      Ancient Friendship: Humans and Dogs Bonded 12,000 Years Ago

      Humans and canines in the Americas formed close relationships 12,000 years ago, earlier than previously thought. Archaeological findings in Alaska, including a 12,000-year-old canine tibia and an 8,100-year-old jawbone, indicate these animals relied on humans for food, such as salmon, rather than hunting independently.

      Teens’ Views on Cannabis Tied to Perceptions of Parental Use

      Teens who perceive their parents use cannabis are more likely to hold favorable views toward the drug and express intentions to try it. The impact of parental cannabis use perception varies by parent gender, with closeness to mothers and fathers influencing teens’ attitudes differently.

      Newly Discovered Brain Circuit Predicts Response to Stress

      Researchers identified a brain circuit involving the amygdala and hippocampus that predicts resilience to stress in mice. Mice with disrupted neural communication in this circuit struggled to seek rewards, but activating the neurons restored resilience and improved decision-making.
