A study by Columbia engineers and psychiatrists reveals that avoidant grievers unconsciously monitor and block their mental state to prevent painful thoughts. The researchers used neural decoding to track the interactions between mental processes, showing that this control occurs outside of conscious awareness.
Researchers used brain scans to identify patterns that distinguish individuals with DID from healthy controls, achieving an accuracy of 73%. The study provides the first evidence of a biological basis for diagnosing DID, potentially preventing unnecessary suffering through earlier and more accurate diagnosis.
A study in Biological Psychiatry found that individuals with childhood maltreatment have altered brain networks, but those who are resilient may have additional changes that compensate for the effects of maltreatment. These changes can help predict susceptibility or resilience to psychiatric symptoms.
Researchers at The Ohio State University found that eliminating microglia can reverse some aspects of stress sensitization, but not increased anxiety. Microglia hold unique signatures of chronic stress and play a critical role in the recurrence of anxiety after chronic stress.
A new study shows that fewer Americans have serious psychological distress, but those with less distress are getting more outpatient mental health care. The growth in treatment is driven by people with little or no distress, while those with serious distress often don't receive the care they need.
Research from RCSI found that one quarter of individuals who attempted or died by suicide had problems with basic sensory experiences, such as hearing or seeing things that aren't real. This dysfunction can predict suicidal behavior and offers new avenues for treatment and suicide prevention.
A new specialist programme at South London and Maudsley NHS Foundation Trust has been shown to significantly reduce hospital readmissions for people with bipolar disorder. The OPTIMA Mood Disorders Service provides intensive, specialist treatment tailored to individual needs, resulting in lower rates of re-admission.
A new study highlights the need for a shift in mental health provision based on public views and individual perspectives. Mental health professionals should adapt their practice to acknowledge patients' beliefs and preferences, rather than relying on assumed assumptions.
A Michigan Medicine study finds that nearly half of suicidal adolescents who watched Netflix's '13 Reasons Why' reported an increased suicide risk, highlighting the need for parental vigilance and tailored prevention programming. The majority of teens who discussed their reactions with peers did so without a parent's involvement.

A new study published in Biological Psychiatry found that high maternal cortisol levels during pregnancy are associated with anxious and depressive-like behaviors in female offspring at the age of 2. The effect is linked to altered brain connectivity, particularly in the amygdala region important for emotion processing.
A study found that frequent tobacco smokers had a nearly 20% decrease in CB1 receptors across the brain, similar to previous findings in cannabis and alcohol abuse. This reduction may be associated with addiction and could have negative effects on normal brain functions like memory and stress coping.

The study's findings suggest that a universal feature of these transport proteins may ...
A new study using machine learning has identified four brain-based dimensions of mental health disorders, including mood, psychosis, fear, and disruptive externalizing behavior. These findings suggest that psychiatric symptoms do not neatly fall into established categories, but instead emerge from diverse clinical domains to form dimen...
A study by researchers at IRCCS Santa Lucia Foundation and University of Rome found that childhood adversity alters the immune system, increasing sensitivity to cocaine in adulthood. Exposure to psychosocial stress early in life leads to permanent changes in immune function, sensitizing the body to cocaine's effects.

A Facebook-based treatment program found that smokers are 2.5 times more likely to quit after three months compared to an online quit-smoking program. Young adults, who are often reluctant to seek help, showed high engagement and short-term abstinence rates.
The article highlights significant flaws in the design, implementation, and analysis of pharmacogenetic tests for treating major depressive disorder (MDD) and related psychiatric conditions. The researchers argue that these tests are not supported by robust evidence and may provide misleading information.
A new study identifies a brain abnormality associated with a person's general risk for mental illness, found in participants with higher mental health liability. The study suggests a single risk factor may predict development of any form of psychiatric disorder.
A study of 133 veterans found that a gene variant may increase psychiatric symptoms, such as PTSD and depression, after traumatic brain injury. The researchers suggest possible explanations for this link, including the gene's effect on emotion regulation and vascular disease.
Researchers found that brain regions responsible for understanding what we see have trouble communicating with other brain networks, increasing risk of mental illness. This breakdown may help target interventions and therapies.

A new study found that a family history of psychiatric disorders, especially bipolar disorder, increases the risk of postpartum psychiatric conditions in mothers. The risk is higher when there's a male relative with a psychiatric disorder, and it's more pronounced among women without prior mental health issues.
A new study found that children with greater parent-child communication have better brain connectivity, leading to lower harmful alcohol use and emotional eating in young adulthood. The research highlights the importance of parenting skills in childhood for long-term brain development and health behaviors.
