Proof-of-concept randomized controlled trial of single-session nitrous oxide treatment for refractory bipolar depression: Focus on cerebrovascular target engagement.

Background: There remain few efficacious treatments for bipolar depression, which dominates the course of bipolar disorder (BD). Despite multiple studies reporting associations between depression and cerebral blood flow (CBF), little is known regarding CBF as a treatment target, or predictor and/or indicator of treatment response, in BD. Nitrous oxide, an anesthetic gas with vasoactive and putative antidepressant properties, has a long history as a neuroimaging probe.

Nitrous oxide as a putative novel dual-mechanism treatment for bipolar depression: Proof-of-concept study design and methodology.

Introduction: Depressive symptoms predominate in the course of bipolar disorder (BD) and there is an urgent need to evaluate novel application of repurposed compounds that act on pre-specified treatment targets. Several lines of reasoning suggest that nitrous oxide (NO) is an ideal medication to study as a potential treatment and as a strategy to identify the underlying pathophysiology of bipolar depression. NO is a potent cerebral vasodilator and there is compelling evidence of reduced frontal cerebral blood flow (CBF; i.

Similarities and Differences Across Bipolar Disorder Subtypes Among Adolescents.

To compare demographic, clinical, and familial characteristics across bipolar disorder (BD) subtypes in adolescents. A total of 168 participants, 13 to 19 years of age, with BD-I ( = 41), BD-II ( = 68), or operationalized BD-not otherwise specified (NOS) ( = 59) were recruited from a tertiary subspecialty clinic at an academic health sciences center. Diagnoses were determined using the semistructured K-SADS-PL (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version) interview.

Elevated Familial Cardiovascular Burden Among Adolescents With Familial Bipolar Disorder.

Bipolar disorder (BD) is one of the most heritable medical conditions, and certain phenotypic characteristics are especially familial in BD. BD is also strongly associated with elevated and premature cardiovascular disease (CVD) morbidity and mortality. Thus, far, little is known regarding the familiality of cardiovascular risk in BD.

Elementary school children's cheating behavior and its cognitive correlates.

Elementary school children's cheating behavior and its cognitive correlates were investigated using a guessing game. Children (n=95) between 8 and 12 years of age were asked to guess which side of the screen a coin would appear on and received rewards based on their self-reported accuracy. Children's cheating behavior was measured by examining whether children failed to adhere to the game rules by falsely reporting their accuracy.

Caucasian infants scan own- and other-race faces differently.

Young infants are known to prefer own-race faces to other race faces and recognize own-race faces better than other-race faces. However, it is entirely unclear as to whether infants also attend to different parts of own- and other-race faces differently, which may provide an important clue as to how and why the own-race face recognition advantage emerges so early. The present study used eye tracking methodology to investigate whether 6- to 10-month-old Caucasian infants (N = 37) have differential scanning patterns for dynamically displayed own- and other-race faces.
