Researchers found that serotonin transporter binding potential values were higher in fall and winter, suggesting a link between lower serotonin levels and seasonal mood changes. The study suggests that variations in brain serotonin levels may explain why people feel happier on sunny days and more sluggish during the dark winter season.
A study found that low-birth-weight children are more likely to experience externalizing and internalizing psychiatric problems, as well as attention problems in urban communities. Early interventions may improve attention skills and lead to better outcomes later.
A new study suggests that blocking the corticotrophin releasing factor-1 (CRF1) receptor and the vasopressin-1B (V1B) receptor may retain their efficacy in treating depression, even when neurogenesis is disrupted. The researchers found that restoration of the stress axis may be key to how these new antidepressant approaches work.
Researchers found that chronic stress alters the genetic immune response by changing the pattern of gene expression in monocytes, a type of white blood cell involved in the body's immune response. This altered response can lead to increased inflammation and contribute to the risk for illnesses like depression, heart disease, and diabetes.
Researchers found that excessive drug use causes increased brain connections as a defense mechanism against addiction. Boosting MEF2 protein activity may help combat addiction, according to the study.

Patients with antisocial personality disorder elicit feelings of distance, while those with avoidant personality disorder induce feelings of helpfulness.
A new report suggests that switching from a selective serotonin reuptake inhibitor (SSRI) to a non-SSRI antidepressant may be more effective for treating symptoms of major depressive disorder. However, the effectiveness and tolerability of this approach varied depending on the individual.
A new study using fMRI found that people with depression show increased activation in the anterior cingulate region when anticipating reward, indicating a conflict between processing rewards and punishments. This finding suggests that depression may not be solely the absence of pleasure, but rather an experience of emotional pain or fr...
Researchers examined two emotion regulation strategies: reappraisal and suppression. Reappraisal reduced negative emotions and activated prefrontal cortex, while suppression increased amygdala activity. These findings suggest reappraisal as a more successful coping strategy.
A study found reduced gray matter density in the pregenual anterior cingulate cortex of combat-exposed veterans with PTSD, but not their identical twins. The researchers suggest that stress exposure may cause this damage, leading to emotional consequences.
Researchers found approximately one in every two hundred genes showed an epigenetic difference in the brains of psychiatric patients. These changes were noted on genes involved in neurotransmission, brain development, and other processes linked to disease origins.
Researchers have discovered a strong link between gene variants and anxiety-related traits, including shy behavior in children and introverted personality in adults. These variations were associated with increased activity of brain regions involved in emotional processing.

The study also found that the MEGF10 gene is expressed more extensively in post-mortem brain tissue from individuals with schizophrenia.
A new study found that clozapine was approximately twice as effective as high-dose olanzapine in treating adolescents with schizophrenia. Both medications produced significant weight gain and metabolic abnormalities, but clozapine showed greater symptom reduction for positive and negative symptoms.
A new study published in Biological Psychiatry reveals that mothers' brains show distinct activation patterns when identifying their own infant's cries versus those of other infants. This unique response is thought to be biologically meaningful for successful infant care.
Researchers at Indiana University School of Medicine have isolated biomarkers in the blood that identify mood disorders, providing an objective tool for diagnosing and assessing the severity of illness. The discovery may alter the way bipolar illness is diagnosed and treated, offering a new approach to psychiatric treatment.
A new approach identifies five genes involved in myelination and six genes involved in growth factor signaling as potential biomarkers for high and low mood states. The study suggests that blood biomarkers may offer an informative window into brain functioning and disease state.

A meta-analysis of 34 clinical trials found venlafaxine (SNRI) outperformed SSRIs in treating depression, resulting in a 5.9% increased remission rate. This translates to the need for doctors to treat 17 patients with venlafaxine to achieve one patient's benefit.
A new study by Yale School of Medicine researchers found that older women are more prone to depression and less likely to die from it compared to older men. The study, which evaluated 754 individuals aged 70+, found that women were more likely to experience symptoms of depression and remain depressed over time.
A study found that older women are more likely to develop depression and remain depressed over time, whereas older men are less prone to this condition. This disparity contributes to the higher burden of depression among older women.
A new study published in Perspectives in Psychiatric Care shows that a psychiatric consultation team working closely with hospital staff led to the elimination of patient restraints for those with mental and developmental disabilities. The use of restraints was reduced through better communication, support, and staff training.
