Social hierarchies are not just a human phenomenon; they’re prevalent in the animal kingdom too, particularly among social creatures like mice. A groundbreaking study on isogenic C57BL/6 mice has shed light on the intricate mechanisms that govern social hierarchy, particularly focusing on the role of dopamine and stress response. This discovery not only enhances our …
Depression, a common yet complex mental health disorder, has various treatment options, including psychotherapies like Non-Directive Supportive Therapy (NDST). A recent meta-analysis sheds light on the effectiveness of NDST in treating depression, comparing it with control conditions and other therapies. Highlights: NDST has been identified as a moderately effective treatment for depression compared to control …
Recent research in the Australian Genetics of Depression Study reveals a fascinating connection between an individual’s chronotype and the efficacy of antidepressants. A study, focusing on selective-serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), suggests that evening chronotypes may experience poorer responses to these medications. Highlights: Chronotype Impact: Individuals with an evening chronotype reported …
In the intricate world of neuropsychiatric research, the role of serotonin in stress-related behaviors and disorders has long been a topic of fascination. Recent studies on rats have shed new light on this area, revealing intriguing ways in which genetics influence anxiety, depression, and neuroplasticity. Highlights: Serotonin Transporter Genes Influence Stress Behaviors: Rats with modified …
A recent study examined how our genetic makeup influences our temperament traits, particularly in relation to depression. By analyzing the polygenic risk for depression (PRS) and its correlation with various temperament traits over time, this research provides significant insights into the complex interplay between genetics and mood. Highlights: High PRS Linked to Increased Persistence: Individuals …
Major depressive disorder (MDD) affects millions worldwide, yet its underlying causes remain largely enigmatic. A new study integrated neuroimaging, transcriptomic, and epigenetic data to better understand the genetic underpinnings of MDD. This comprehensive approach revealed a complex interplay between brain structure, gene expression, and DNA methylation, offering new insights into this debilitating condition. Highlights: Integrative …
Patients with severe mental illnesses (SMI), such as schizophrenia and chronic depression, often face the challenge of managing weight gain and metabolic complications, side effects commonly associated with antipsychotics and antidepressants. These medications are known to induce increased appetite and weight gain, leading to long-term metabolic syndromes. Recent studies have evaluated into the role of …
