The treatment target specific alpha oscillations in the brain, bringing them back into balance and decreasing symptoms.
The revised guidelines address pharmacogenetics, diagnosis of mental disorders with new molecular genetic technologies, and ethical challenges of genetic testing in psychiatric patients. Key findings include a lack of consensus on CNV testing in adults with mental illness and the need for more research to identify relevant genes.
Deep brain stimulation (DBS) of the ventral capsule (VC) or anteromedial subthalamic nucleus (amSTN) reduced OCD symptoms to a similar extent, but produced distinct effects on specific symptoms. VC stimulation improved mood, while amSTN stimulation improved cognitive flexibility.

Children as young as four years old who expressed suicidal ideation demonstrated a solid understanding of death concepts, including the possibility of violent causes.
Researchers found that psychiatric readmissions occur later in the postpartum period, with younger women and those with multiple gestations at increased risk. Obstetric care providers should be aware of these risk factors to optimize postpartum care for at-risk women.
A new study finds that people with psychosis experience accelerated aging of brain networks important for general cognition, but at a faster rate than healthy individuals. This accelerated decline can be a promising target for early intervention and cognitive remediation strategies to improve functional outcomes.
A major Australian study has found that suicidal thoughts do not accurately predict suicide, challenging a widely held belief. The meta-analysis of 70 studies showed that only 1.7% of people with suicidal ideas died by suicide, while about 60% of those who did die had denied having suicidal thoughts.

This suggests a distinct mechanism underlying the biology of schizoaffective disorder, which shares symptoms with schizophrenia.
Reactive attachment disorder is a social functioning disorder characterized by ambivalence towards comfort and emotional withdrawal. A study of 614 children with RAD found that parents' psychiatric diagnoses increased the child's risk by nine-fold for mothers and six-fold for fathers.
A mouse model of traumatic memory found that male mice recall fear-related memories better than female mice due to natural activation of cyclin dependent kinase 5 (Cdk5) in males. Artificial activation of Cdk5 reduced the strength of fear memories in female mice, highlighting sex differences in how fear is remembered.
The study analyzed register data from 5.9 million people in Denmark, uncovering how different types of mental disorders accumulate across a lifespan.

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.

High cessation fatigue scores predicted lower chances of going a full week without smoking at two months.
Rutgers is creating a regional Mental Health Technology Transfer Center to train mental health practitioners and support the implementation of evidence-based research. The center will focus on increasing access to treatment, prevention, and recovery services for underserved populations.
Researchers discovered that toddlers with autism spectrum disorder display enhanced anger and frustration but decreased fear in response to naturalistic situations. The capacity to experience joy appears intact in the early stages of the disorder, which may help harness emotional competence for therapeutic purposes.
A nationwide study found that mental health diagnoses and treatment among college students increased substantially between 2007 and 2017. The study also revealed a significant decrease in mental health stigma over the same period.
A study published in Biological Psychiatry found that exposure to early life violence accelerates biological aging, including pubertal development, while deprivation-related adversity leads to delayed pubertal development. Children who experienced violence showed signs of accelerated epigenetic aging and increased symptoms of depression.
Researchers have established an in vitro model of human neuron development to investigate the complex genetic origins of mental illnesses. The study found that changes in gene expression during neural development were significantly associated with genetic risk for schizophrenia.
