Brain Activation Patterns May Help Predict Bipolar Disorder Risk

New research indicates that patterns of brain activation during reward anticipation may help identify people most at risk for developing bipolar spectrum disorders. Mania in people with bipolar spectrum disorders (BPSD) is often accompanied by impulsivity, including impulsive responses to potential rewards. In this new study, patterns of neural activation during a reward task predicted […]

Disrupted Circadian Rhythm May Have Genetic Link To Mood Disorders

A potential genetic link between circadian disruption and mood disorders has been identified by scientists at the University of Glasgow. Circadian rhythms are regular 24-hour variations in behaviour and activity that control many aspects of our lives, from hormone levels to sleeping and eating habits. The new findings, from the largest ever genome wide association […]

Nucleus Gigantocellularis Neurons May Play Role In Cognition

New research sheds light on an area of the brainstem that is so little understood the first author of the paper, Rockefeller University’s Inna Tabansky, calls it β€œthe black box.” Many traits of our central nervous system depend on an underappreciated deep brain mechanism that Donald Pfaff, head of the Laboratory of Neurobiology and Behavior […]

Nitrate-cured Meats Associated With Manic Episodes

Nitrates β€” chemicals used to cure meats such as beef jerky, salami, hot dogs and other processed meat snacks β€” may contribute to mania, an abnormal mood state, a Johns Hopkins Medicine analysis of more than 1,000 people with and without psychiatric disorders has found. Mania is characterized by hyperactivity, euphoria and insomnia. The study, […]

Schizophrenia And Bipolar Disorder Shared Genetic Risks Categorized

Symptoms of bipolar disorder and schizophrenia, including psychosis, depression and manic behavior, have both shared and distinguishing genetic factors, reports an international group led by researchers from Vanderbilt University and Virginia Commonwealth University. The findings raise hopes that genetics could help characterize and eventually inform more effective treatment options for patients with these brain disorders. […]
