The study suggests a focus on replication is necessary to confirm accurate correlations between genes and environmental variables.
A new study investigates the paternal transmission of stress and its impact on children's mental health. Researchers found that male mice exposed to chronic stress passed those stress behaviors along to their offspring, increasing depression and anxiety-like behaviors in both males and females.
A new study suggests that differences in brain activity, particularly in the frontal lobe and visual areas, can predict depression relapse in formerly depressed patients. Those who ruminate and activate the frontal lobes are more likely to relapse.
Research reveals that depression-related rumination is associated with a brain network imbalance, where the default mode network (DMN) dominates over the task-positive network (TPN). This imbalance leads to maladaptive thinking and less effective coping mechanisms, exacerbating depressive symptoms.
Research shows antipsychotics are more effective than mood stabilisers in tackling acute mania. Haloperidol, olanzapine, and risperidone were ranked most effective antimanic drugs, with haloperidol outperforming other options.
A study published in Psychological Medicine found that psychiatrists are not regularly monitoring patients for metabolic complications associated with antipsychotic medication. The researchers reviewed over 300,000 individuals across five countries and found that only half of patients had blood pressure and triglyceride checks conducted.

The researchers also found correlations between molecular changes and biomarkers, paving the way for targeted clinical studies in humans.
A new tool, REMIT, has been developed to improve the measurement of primary care depression outcomes. The tool adds a patient's subjective sense of recovery to existing measurements, showing that about one-third of patients with mild depression were not in remission, as their PHQ score would indicate.
Researchers used EEG to measure brain's response to tones, finding smaller mismatch negativity in individuals who developed schizophrenia. The test showed promise as a potential predictor of psychosis development.
Researchers at Washington University and King's College London have independently identified a DNA region on chromosome 3 associated with depression. The region contains up to 90 genes and shows genome-wide significance, suggesting that many genes may be involved in depression.
A recent survey led by McGill Psychiatry Professor Amir Raz found that one in five respondents, mostly psychiatrists, have administered or prescribed placebos. The majority of responding psychiatrists (more than 60%) believe that placebos can have therapeutic effects.
Research studies found that vulnerable individuals with genetic deletions on chromosome 22, known as velocardiofacial syndrome (VCFS), are at risk for developing schizophrenia. Progressive brain abnormalities emerge during adolescence, including deficits in the volume of temporal cortex gray matter, which predicts psychosis.
Researchers at Wayne State University have found a new method to identify children with major depressive disorder (MDD), setting them apart from both healthy children and those with obsessive compulsive disorder (OCD). Cortical thickness in the brain was used as a key factor, revealing distinct differences between MDD patients and heal...
Children whose mothers are successfully treated for depression show progressive improvement in their own behaviors even a year after treatment discontinuation. The faster mothers get better, the faster and greater their children's improvements are.
A study from Massachusetts General Hospital finds that siblings of individuals with both ADHD and emotional reactivity have a significantly greater risk of having both conditions. This suggests that heritable factors influence how we control our emotions, and that ADHD can impact emotional expression beyond classic symptoms.
Researchers have developed a mouse model that mimics the social deficits of autism and schizophrenia, showing improved social behavior with oxytocin treatment. The study provides insights into biological factors related to social deficits and may be useful in evaluating new treatments for these disorders.
A UK survey found that adults with autism were rarely aware they had the condition, with prevalence higher in males and lower educated individuals. The study suggests that changes in diagnosis methods may be responsible for recent increases in reported cases.
A new study suggests that individuals with autism have a weak mirror neuron system in their youth, but it increases with age and becomes unusually high thereafter. This delay in development may be related to increased capacity for social function or responsiveness to rehabilitative treatments.
A University of Melbourne study found that male doctors are four times more likely than female doctors to face disciplinary action for misconduct. The majority of cases involved sexual misconduct, which was responsible for 24% of all cases handled by tribunals.
Researchers analyzed data from the largest study on depression treatment, finding that even responders experience residual symptoms like insomnia and decreased concentration. The study suggests a need for more targeted antidepressant therapies to decrease depressive symptoms and understand their association with concentration.
Researchers found that a teacher-based intervention reduced PTSD symptoms in war-exposed children by 50% compared to a control group. The study suggests that this universal and cost-effective approach can enhance community preparedness for mass trauma and prevent PTSD development.
A new study published in Biological Psychiatry suggests that serotonin activity affects how people perceive intimate relationships. Healthy adults with lower serotonin levels rated couples as less intimate and romantic than those with normal serotonin activity.
Scientists have discovered how anti-depressants make new brain cells by regulating the glucocorticoid receptor, a key protein involved in stress response. This finding holds promise for developing more effective anti-depressant treatments to combat depression.
Researchers found that thiazolidinediones (TZDs) and fibrates, commonly used to treat type-2 diabetes, may help counteract nicotine and alcohol addiction by activating specific receptors in the brain. These drugs stimulate PPAR-α and PPAR-γ receptors, reducing inflammation and increasing high-density lipoprotein (HDL) levels.
Researchers found that people who experience stronger stimulating and lower sedative effects of alcohol are more likely to develop binge drinking problems. A new study published in Archives of General Psychiatry suggests that the 'double whammy' of alcohol effects predicts those who progress to severe drinking and alcohol-use disorders.
