Impulsivity, inattention and poor behavioral inhibition are common deficits in pediatric bipolar disorder (PBD) and attention deficit hyperactivity disorder (ADHD). This study aimed to identify similarities and differences in the neural substrate of response inhibition deficits that are associated with these disorders. A functional magnetic resonance(More)
OBJECTIVE This functional magnetic resonance imaging (fMRI) study examined how working memory circuits are affected by face emotion processing in pediatric bipolar disorder (PBD) and attention-deficit/hyperactivity disorder (ADHD). METHODS A total of 23 patients with PBD, 14 patients with ADHD, and 19 healthy control (HC) subjects (mean age, 13.36 ± 2.55(More)
OBJECTIVE To identify barriers to seeking help for preschool behavior problems and understand the pattern of service utilization. METHOD Altogether, 320 preschool children from eight preschool centers were studied using a two-stage design. After the initial screening, a more detailed assessment was carried out in the second stage involving semistructured(More)
BACKGROUND To investigate microstructure of white matter fiber tracts in pediatric bipolar disorder (PBD) and attention-deficit/hyperactivity disorder (ADHD). METHODS A diffusion tensor imaging (DTI) study was conducted at 3 Tesla on age- and IQ-matched children and adolescents with PBD (n = 13), ADHD (n = 13), and healthy control subjects (HC) (n = 15).(More)
The pathophysiology of pediatric bipolar disorder (PBD) impacts both affective and cognitive brain systems. Understanding disturbances in the neural circuits subserving these abilities is critical for characterizing developmental aberrations associated with the disorder and developing improved treatments. Our objective is to use functional neuroimaging with(More)
BACKGROUND Facial emotions are central to human interaction. Identifying pathophysiology in affect processing circuitry that supports the ability to assess facial emotions might facilitate understanding of affect regulation in pediatric bipolar disorder. METHODS Ten euthymic, unmedicated pediatric bipolar patients and 10 healthy control subjects matched(More)
This fMRI study investigates the neural bases of cognitive control of emotion processing in pediatric bipolar disorder (PBD) and attention deficit hyperactivity disorder (ADHD). Seventeen un-medicated PBD patients, 15 un-medicated ADHD patients, and 14 healthy controls (HC) (mean age = 13.78 +/- 2.47) performed an emotional valence Stroop Task, requiring(More)
OBJECTIVE A systematic evaluation of neuropsychological functioning in individuals with pediatric bipolar disorder is necessary to clarify the types of cognitive deficits that are associated with acutely ill and euthymic phases of the disorder and the effects of medication on these deficits. METHOD Unmedicated (N=28) and medicated (N=28) pediatric bipolar(More)
OBJECTIVE To review the literature of the past decade covering the epidemiology, clinical characteristics, assessment, longitudinal course, biological and psychosocial correlates, and treatment and prevention of pediatric bipolar disorder (BD). METHOD A computerized search for articles published during the past 10 years was made and selected studies are(More)
OBJECTIVE This prospective 6-month open trial examined the safety and efficacy of two combination therapies for manic or mixed episodes of pediatric bipolar disorder: (1) divalproex sodium plus risperidone (DVPX+Risp), or (2) lithium plus risperidone (Li+Risp). METHODS Thirty-seven (37) subjects aged 5 and 18 (age=12.1+/-3.5 years) with DSM IV current(More)
