A large study of 350,000 cases over 15 years found no higher suicide risk in clinics with locked wards compared to those with open-door policies. The study suggests that a controlled atmosphere may actually hinder successful therapy and patient autonomy.
Researchers found that brain dopamine function returns to normal three months after quitting smoking, indicating chronic smoking may cause smoking-related deficits. This suggests the possibility of treatments targeting dopamine systems in smokers.
Researchers recommend measures to reduce US firearm suicide rates, including targeted legislation and smart gun technology. Public education and research are also crucial in preventing firearm suicides.
A new 15-year study of 145000 patient cases found that locked wards do not reduce the risk of suicide attempts or unauthorized absence from hospital. In contrast, patients treated on open wards are less likely to attempt suicide and have a lower likelihood of absconding.
Researchers found that low UPSIT scores predicted dementia and cognitive decline in older adults, while entorhinal cortical thickness was associated with UPSIT score in those who transitioned to dementia. Odor identification testing may be useful in detecting early-stage Alzheimer's disease.
A recent study found that adults with moderate or more severe pain are at a 41% higher risk of developing prescription opioid use disorders. The study, published in the American Journal of Psychiatry, analyzed data from over 34,000 adults and confirmed previous findings on age and sex as risk factors.
A recent study examined opioid agonist therapy (OAT) use among Medicare Part D beneficiaries.

A national survey of over 34,000 adults found that individuals with bipolar disorder are equally likely to develop anxiety as depression after experiencing an episode of mania. This study may lead to a broader clinical definition of bipolar disorder that includes episodes of mania along with anxiety or depression.
Experts weigh the benefits of expanding buprenorphine prescribing, citing its effectiveness in reducing opioid mortality rates, but also raising concerns about misuse and diversion. Proposed strategies aim to ensure safe and effective use while promoting quality care.
Researchers identified four previously unknown genetic conditions within schizophrenia, each with distinct symptoms and disease features. The study provides a framework for finding influential genes across complex genetic diseases, enabling more precise treatment design.
A meta-analysis of nine published randomized trials found that mindfulness-based cognitive therapy (MBCT) was associated with a reduced risk of depressive relapse/recurrence over 60 weeks. The treatment effect appeared to be larger in patients with higher levels of depression symptoms at baseline.
Researchers found structural brain damage in the hippocampus, a key memory region, that correlates with memory performance and disease severity in patients with anti-NMDA receptor encephalitis. The autoimmune disorder can cause schizophrenia-like symptoms and long-term cognitive impairment if not treated promptly.
A study of nearly 700 ICU survivors found that two-thirds experienced depression, anxiety, or PTSD, with most experiencing multiple symptoms. The risk factors were not related to illness severity or length of stay, but rather age, gender, unemployment, and substance misuse.
A study using Swedish registry information found that individuals with alcohol use disorder (AUD) experience excess mortality, with both predisposition and AUD itself contributing to the risk. The study suggests that interventions targeting AUD could lead to reduced mortality rates among those affected.
A study published in JAMA Psychiatry found that U.S. veterans who experienced military sexual trauma were at a higher risk of postdeployment homelessness. The study analyzed data from over 601,000 veterans and found that those with positive MST screens had significantly higher rates of homelessness compared to those without.
New research finds that implementing specialist community services, clinical guidelines, and staff retention improvements led to significant reductions in patient suicide rates. Higher levels of non-medical staff turnover were linked to higher suicide rates.
A study by Columbia University Irving Medical Center found that heavy cannabis users have lower dopamine release in the brain's striatum, a region involved in working memory and attention. This effect is similar to other addictive substances and may impair learning and behavior.
Researchers developed a novel method for predicting attention impairment using brain network growth charts in young people. The study found associations between deviations from normative maturation patterns and impaired sustained attention performance, as well as ADHD diagnosis.
A new study found that low-risk drinking guidelines differ significantly across countries, reflecting varying attitudes towards alcohol consumption. Different countries assign distinct daily or weekly limits for men and women, leading to confusion among researchers and the public.
Researchers have identified a range of neurological and psychiatric symptoms in Ebola survivors, including vision complications and joint pain. The study's findings highlight the need for improved treatment options for those affected by post-Ebola syndrome.
Researchers found that depression combined with metabolic risk factors significantly increases the risk of developing type 2 diabetes. The study suggests a vicious cycle where depression and metabolic symptoms exacerbate each other, making integrated treatment crucial for prevention.
A randomized clinical trial found that injectable hydromorphone was noninferior to injectable diacetylmorphine in treating long-term severe opioid dependence. The study suggests that hydromorphone could be a licensed alternative for patients where diacetylmorphine is unavailable or unsuccessful.
A study of over 2,000 US veterans found nearly 14% reported suicidal thinking at one or both survey phases, challenging past findings that suggest it's a longer-term problem. Social connectedness was linked to remission, while addressing psychiatric and physical health issues may be more critical for those with chronic suicidal thinking.
Researchers at Indiana University have identified blood-based biomarkers and developed questionnaire-based apps that can help clinicians identify female patients at greatest risk of suicidal ideation or behavior. The study found that these tools were able to predict future instances of suicidal thoughts with high accuracy, suggesting p...
A new study has identified a pattern of brain activity linked to memory problems in people with schizophrenia. The findings provide evidence that the dorsolateral prefrontal cortex is compromised in patients with schizophrenia and may be a specific target for treatment.
A genome-wide association study found that specific genetic variants contribute to cannabis dependence, potentially overlapping with other psychiatric conditions. The study also suggests a risk component for cannabis dependence in relation to other substance use disorders.

Child abuse was linked to various mental disorders, including post-traumatic stress disorder and panic disorder.
A study by Columbia University Irving Medical Center found that medical marijuana programs with less regulation had higher enrollment rates, raising concerns about potential recreational users. The analysis of state-specific characteristics highlights the need for policymakers to differentiate among programs to interpret the effects of...
A novel psychiatric intervention called Attempted Suicide Short Intervention Program (ASSIP) has been shown to reduce the risk of suicide re-attempts by 80% in patients who have attempted suicide. The study found that ASSIP participants experienced a significantly lower rate of repeat attempts compared to those who received standard care.
A new study from Trinity College Dublin reveals that modifying ECT can minimize cognitive side effects while maintaining its effectiveness in treating severe depression. The 'unilateral' approach, involving unilateral electrode placement, shows promising results.

After 12 months, participants in the active ABM group reported even greater reductions in self-reported depressive and anxious feelings.
A study by the University of Helsinki found that young people with psychotic-like symptoms benefit from early intervention treatment in their own environment. The treatment approach improved functioning and reduced symptoms compared to conventional youth psychiatric treatment.
