"The Influence of Wealth on the Brain's Reward Response"

A study by MIT neuroscientists found that children from lower socioeconomic status (SES) backgrounds exhibit less activation in the reward-linked striatum during a money-earning game, indicating reduced sensitivity to rewards compared to those from higher SES backgrounds. This reduced reward sensitivity in lower SES children is hypothesized to be an adaptation to their environment, which typically offers fewer consistent rewards. The research underscores the profound impact of socioeconomic factors on brain development and behavior, highlighting the importance of including diverse SES backgrounds in studies to fully understand brain development variations.

Predicting Mania Risk in Bipolar Spectrum Disorders Using Neurobehavioral Profiles and Polygenic Signatures

A recent study has identified neurobehavioral profiles that can predict the risk of future mania or hypomania in bipolar spectrum disorders (BSD). The study found three profiles: healthy, moderate risk, and high risk, based on factors such as reward sensitivity, impulsivity, and sleep-circadian characteristics. Individuals in the high-risk and moderate-risk groups showed more symptoms of mania over a 12-month period compared to those in the healthy group. The findings may help detect mania risk earlier and inform intervention strategies.

Unveiling the Link Between Neural Responses and Suicidal Ideation

The way the brain responds to rewards and losses may serve as a brain-based marker for suicidal ideation in individuals with depression and social anxiety, according to a study published in Biological Psychology. The researchers found that lower reward sensitivity was associated with higher levels of suicidal ideation, regardless of the specific diagnosis. Cognitive-behavioral therapy and supportive therapy were both effective in reducing symptoms of social anxiety and depression, but reward sensitivity remained stable throughout treatment, suggesting it may be a vulnerability marker for suicidal thoughts. Further research is needed to replicate the findings and explore other potential pathways leading to suicidal ideation.
