There is a limited understanding of the physiological effects of state and trait mindfulness, and it has been a challenge to the research community to measure these ef...

Objectives: Despite increasing evidence of excessive substance use disorder (SUD) prevalence among adolescents with bipolar disorder (BP), little is known about this topic among Canadian adolescents with BP. We therefore sought to examine the clinical characteristics and dimensional measures of psychopathology associated with comorbid SUD among Ca...

The article reviews systemic and context-specific challenges of psychoeducational assessment using two case studies: a 19-year-old woman with feigned attention-deficit/ hyperactivity disorder and a 50-year-old man with genuine dyslexia. These cases demonstrate that providing a thorough evaluation of performance validity is an essential component of...

Mindfulness has been promoted as a way to increase resiliency during times of stress. Universities are reporting that record numbers of undergraduate students are seeking mental health services related to stress. This study assessed the feasibility of layering brief mindfulness-based practice within a large-scale university course. Data were collec...

Objectives: Cerebral blood flow (CBF) is altered in mood disorders but has not been examined among adolescents with bipolar disorder (BD). Similarly, little is known about the acute neurophysiologic effects of aerobic exercise in BD. We therefore compared CBF between adolescents with and without BD at rest and acutely following a single exercise se...

Executive dysfunction is common during and between mood episodes in bipolar disorder (BD), causing social and functional impairment. This study investigated the effect of acute exercise on adolescents with BD and healthy control subjects (HC) to test for positive or negative consequences on neural response during an executive task. Fifty adolescent...

Objective: The purpose of this study was to examine the prevalence and correlates of disruptive mood dysregulation disorder phenotype (DMDDP) in a clinical population of adolescents with bipolar disorder (BD). Methods: DMDD criteria were modified and applied to a sample of 116 adolescents with BD-I (n = 30), BD-II (n = 46) or BD-not otherwise sp...

Objective: Despite numerous studies regarding obesity (OB) in adult bipolar disorder (BP), there are few studies on this topic among adolescents. The current study attempts to extend the literature on prevalence and correlates of OB in adolescent BP by including control participants, and determining OB by direct measurement. Methods: Participant...

Background: Exercise may be a practical, non-pharmacological strategy for symptom and health management for adolescents with bipolar disorder (BD). The purpose of this study was to determine if adolescents with BD experience changes in exercise-induced feelings from one bout of exercise similar to their otherwise healthy peers.

Background: Little is known regarding correlates of borderline personality-spectrum symptoms (BPSS) among adolescents with bipolar disorder (BP). Methods: Participants were 90 adolescents, 13-19 years of age, who fulfilled DSM-IV-TR criteria for BP using semi-structured diagnostic interviews. BPSS status was ascertained using the Life Problems I...

Objective To identify factors associated with psychiatric hospitalization among adolescents with bipolar disorder (BD). Methods Participants were 100 adolescents, ages 13–19, who fulfilled DSM-IV criteria for bipolar I disorder [(BD-I), n = 26], bipolar II disorder [(BD-II), n = 40], or operationalized criteria for BD not otherwise specified [(BD-...

Objective: Little is known regarding demographic and/or clinical characteristics associated with the use of lithium among adolescents with bipolar disorder (BP) in naturalistic clinical settings. We therefore examined factors associated with lithium among adolescents with BP presenting to a tertiary outpatient clinic. Methods: Participants were...
