Meta AnalysisSubcortical brain volume differences in participants with attention deficit hyperactivity disorder in children and adults: a cross-sectional mega-analysis.
Neuroimaging studies have shown structural alterations in several brain regions in children and adults with attention deficit hyperactivity disorder (ADHD). Through the formation of the international ENIGMA ADHD Working Group, we aimed to address weaknesses of previous imaging studies and meta-analyses, namely inadequate sample size and methodological heterogeneity. We aimed to investigate whether there are structural differences in children and adults with ADHD compared with those without this diagnosis. ⋯ National Institutes of Health.

Clinical TrialDeep brain stimulation of the subcallosal cingulate for treatment-refractory anorexia nervosa: 1 year follow-up of an open-label trial.
Anorexia nervosa is a life-threatening illness. Brain circuits believed to drive anorexia nervosa symptoms can be accessed with surgical techniques such as deep brain stimulation (DBS). Initial results suggest that DBS of the subcallosal cingulate is safe and associated with improvements in mood and anxiety. Here, we investigated the safety, clinical, and neuroimaging outcomes of DBS of the subcallosal cingulate in a group of patients during 12 months of active stimulation. ⋯ Klarman Family Foundation Grants Program in Eating Disorders Research and Canadian Institutes of Health Research.

Over the past decade, concussion has become the most widely discussed injury in contact sports. However, concussions also occur in several other settings, such as non-contact sports, elderly individuals, young children, military personnel, and victims of domestic violence. Concussion is frequently undiagnosed as a cause of psychiatric morbidity, especially when the patient has no history of loss of consciousness or direct head trauma. ⋯ In this Review, we address key issues so that the psychiatric clinician can better understand and treat patients with a clinical phenotype that might be the direct result of, or be exacerbated by, concussion. Future research needs to focus on prospective clinical trials in all affected patient populations (ie, those affected by concussion and those affected by various degrees of traumatic brain injury), the identification of reliable biomarkers that can be used to assist with diagnosis and treatment response, and the development of effective treatment interventions. Clearly differentiating concussion from traumatic brain injury is essential to achieve reliable and clinically relevant outcomes.

Randomized Controlled Trial Multicenter StudyEfficacy and cost-effectiveness of a specialist depression service versus usual specialist mental health care to manage persistent depression: a randomised controlled trial.
Persistent moderate or severe unipolar depression is common and expensive to treat. Clinical guidelines recommend combined pharmacotherapy and psychotherapy. Such treatments can take up to 1 year to show an effect, but no trials of suitable duration have been done. We investigated the efficacy and cost-effectiveness of outpatient-based, specialist depression services (SDS) versus treatment as usual (TAU) on depression symptoms and function. ⋯ National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care, UK Medical Research Council, Nottinghamshire Healthcare NHS Foundation Trust, Derbyshire Healthcare NHS Foundation Trust, Cambridgeshire and Peterborough NHS Foundation Trust, University of Nottingham.
