简要总结
This research protocol seeks to learn more about bipolar disorder in children and adolescents ages 6-17. Researchers will describe the moods and behaviors of children with bipolar disorder and use specialized testing and brain imaging to learn about specific brain changes associated with the disorder. This protocol studies children who have been diagnosed with bipolar disorder, and those who have a sibling or parent with bipolar disorder and are thus considered "at risk" for developing the disorder.
详细描述
Objective:
For this protocol we define Bipolar Spectrum disorders (BSD) as the propensity to have a manic episode by having Bipolar Disorder or Substance/Medication-Induced Bipolar and Related Disorder. BSD in children and adolescents is receiving increased research attention, but important questions remain about its developmental trajectory, phenomenology and behavioral correlates, and little is known about its underlying neural mechanisms. In its study of youth with BSD, this study has three objectives:
- to use longitudinal techniques to characterize the clinical and physiological manifestations of pediatric BSD, and to use cross-sectional techniques (e.g., comparing children and adults with BSD on these measures) to provide preliminary data to guide such longitudinal studies
- to identify and follow longitudinally behavioral, neuropsychological, neurophysiological, and neuroanatomical correlates of pediatric BSD, and compare to children with chronic irritability and hyperarousal symptoms (severe mood dysregulation, SMD, as outlined in protocol 02-M-0021), youth with attention deficit hyperactivity disorder (ADHD), and typically developing youth.
- to examine genetic and familial correlates of pediatric BSD
Study population:
There are 11 separate populations being studied in this protocol:

主要结局
Objective 1: clinical manifestations
时间窗: lifetime of protocol
(1) clinical interviews \[e.g., Schedule for Affective Disorders and Schizophrenia for School-Age Children-present and lifetime version, K-SADS-PL, (Kaufman et al., 1997); Structured Clinical Interview for DSM-IV-TR Axis I Disorders, SCID (First et al., 2002)\]; (2) clinical and mood rating assessments (e.g., Children's Depression Rating Scale (Poznanski et al., 1984), Young Mania Rating Scale (Young et al., 1978), Pediatric Anxiety Rating (2002), EMA; (3) episode setting via detailed clinical interview at baseline and every 6 month follow up phone call (4) parent-report and self-report \[e.g., The Screen for Child Anxiety Related Emotional Disorders SCARED (Birmaher et al., 1997); Social Responsiveness Scale, SRS (Constantino et al., 2003, Granader et al.); Child Behavior Checklist CBCL (Achenbach, 1991)\].
Objective 2: behavioral, neuropsychological, neurophysiological, and neuroanatomical correlates
时间窗: lifetime of protocol
1) behavioral performance (e.g., accuracy, response time) on tasks assessing attention, emotion, and attention-emotion interactions; (e.g., Stop/Change task, CPT/Flanker, Decision Making tasks) 2) neuropsychological performance (e.g., performance and verbal IQ) 3) brain activation using functional MRI during tasks assessing attention, emotion, and attention-emotion interactions; 4) structural MRI to examine the size, shape and development of grey matter; 5) Diffusion Tensor Imaging (DTI) to measure white matter track myelination; 6) resting state imaging to test functional connectivity between prefrontal regions and the amygdala
Objective 3: genetic and familial correlates
时间窗: lifetime of protocol
(1) clinical interviews \[e.g., Schedule for Affective Disorders and Schizophrenia for School-Age Children-present and lifetime version, K-SADS-PL, (Kaufman et al., 1997); Structured Clinical Interview for DSM-IV-TR Axis I Disorders, SCID (First et al., 2002)\] to examine the rate of various diagnoses in relatives of individuals with BD (2) genetic material to compare genetic polymorphisms in BSD, their relatives and controls (3) relationship between genetic material and performance on behavioral tasks and activation during fMRI paradigms (4) behavioral performance on standardized paradigms; brain activation using functional MRI; size, shape and development of several ROIs using structural MRI; Diffusion Tensor Imaging (DTI); and, Resting State in individuals with a BD relative
