Filter by:This study will evaluate the effectiveness of a doctor-office collaborative care approach in treating children with disruptive behavior problems in the pediatric primary care setting.
This Protocol is intended to facilitate development and testing of new techniques for functional MRI by UC Davis Research Faculty, as well as to facilitate the evaluation of new techniques provided by the system manufacturers (GE and Siemens).
Does parenting style affect emotion regulation among children who initially demonstrate high levels of fear and anxiety? Although recent correlational research has demonstrated a linkage between parental behaviors, such as excessive intrusiveness, and children's manifestations of fear and anxiety, it is not clear if parenting behaviors directly influence children's ability to regulate these emotions. Alternatively, these parental behaviors may be elicited by children who express fears and anxieties more frequently than other children do. Experimental research designs would offer a more definitive test of these competing explanations of the extant correlational findings. Intervention studies, in particular, can test whether experimentally manipulating current family interaction patterns affects children's ability to regulate emotion. This study provides a preliminary experimental test of the relationship between parental behavior and children's regulation of fear and anxiety. Some 40 clinically anxious youth, aged 6-13, were randomly assigned to a family intervention program for childhood anxiety problems, which includes extensive parent communication training, or a child intervention program without parent-training. By comparing these two interventions, we tested if it was possible to improve parenting behaviors—such as intrusiveness—through intensive parent-training, above and beyond the effects of involving children in a child intervention program. We then tested the impact of this change in parental behaviors on children's ability to regulate fear and anxiety. We hypothesized that parent-training would reduce intrusiveness, which would in turn improve children's anxiety outcomes.
Many patients with schizophrenia and schizoaffective disorder have symptoms that persist, including hallucinations or delusions, despite adequate pharmacotherapy with antipsychotic drug. Glutamate is a major excitatory neurotransmitter in the brain that has been implicated in several brain diseases. NMDA antagonist drugs cause symptoms of psychosis in otherwise normal persons. It is postulated that reduced NMDA receptor mediated neurotransmission leads to an increase in synaptic glutamate. Excessive synaptic concentrations of glutamate can produce excitatory neurotoxicity. Agents which reduce excess glutamate activity are neuroprotective. This therapeutic strategy has been applied to schizophrenia through the use of compounds that reduce presynaptic release of glutamate or otherwise decrease excessive postsynaptic stimulation, including lamotrigine, memantine and a m-GLU-R2 agonist (LY354740) with the hypothesized result of a reduction in psychotic symptoms. Recently it was shown that a commonly available antibiotic (ceftriaxone) has the unique neuroprotective function of decreasing the amount of extracellular glutamate in nervous system tissue by increasing the number of glutamate transporter proteins. Our clinical experience with patients who have refractory psychosis and past Lyme disease indicates that in some patients psychosis may improve with IV ceftriaxone therapy. Whether this improvement was due to its antimicrobial or glutamate effect or a placebo effect is uncertain. In a placebo-controlled design, this study investigates the ability of ceftriaxone to decrease psychotic symptoms in patients with refractory psychotic disorders. In addition, the study will examine glutamatergic functional activity before and after treatment using brain imaging with magnetic resonance spectroscopy.
The study aims to evaluate the effectiveness of a cognitive behaviour therapy program (FRIENDS) for anxiety disorders in children aged 8-15 years who have been referred to child and adolescent mental health clinics in Western Norway.
The primary aims of this study are to assess: 1. The inter-rater and test-retest reliability of the MINI-KID 2. The validity of the standard MINI-KID interview in relation to the parent rated pencil/paper version (MINI-KID-P) and th longer clinician rated "Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime Version (K-SADS-PL) and "expert opinion" (when available). Secondary aims will include evaluating the concordance between: The Children's Global Assessment Scale (a required part of the K-SADS) with the clinician-rated Sheehan Disability Scale (to be administered with the MINI-KID) as a measure of illness severity.
The primary objective of this study is to investigate the relationships among findings in structural and functional neuroimaging, cognitive testing and HPA (hypothalamic-pituitary-adrenal) axis dysregulation in psychotic depression.
This trial is a preliminary study to determine the use of far infrared radiation for the treatment of dementia and other mental sickness.
Many individuals with schizophrenia abuse cannabis at the onset of their illness, portending a poorer course of illness and poorer treatment response. Preliminary evidence suggests that clozapine may uniquely reduce substance use in patients with schizophrenia. The purpose of this study is to establish an effective methodology for studying early treatment with clozapine in patients with co-occurring schizophrenia and cannabis use disorder, while generating pilot data comparing clozapine vs. risperidone on substance use, psychiatric symptoms, side effects, and treatment discontinuation.
Although cognitive behavioral therapy (CBT) has been found to be efficacious in the treatment of child anxiety disorders, little progress has been made in the dissemination of such treatments to real-world practice settings. Clinical trials conducted in practice settings can demonstrate the degree to which evidence-based treatments are appropriate for larger scale dissemination. This study evaluates CBT as a treatment for child anxiety disorders in the elementary school clinic setting. A randomized, controlled trial design has been employed, comparing immediate treatment and a three-month waitlist. The trial is being conducted in several Los Angeles area elementary schools and is only available to children in these particular schools. To ensure that the CBT intervention is flexible and capable of matching the characteristics of various school settings, clinicians, and referred children, a modular treatment approach is employed. The study design includes elements to ensure high quality data, such as the use of independent evaluators and tests of treatment fidelity. Children, ages 5 to 12 years, are referred by teachers and staff or are identified as having high anxiety in concurrent studies. All participating children have DSM-IV diagnoses of separation anxiety disorder, generalized anxiety disorder, or social phobia, according to a semi-structured diagnostic interview. Therapy and clinical supervision is provided by the research team. It is hypothesized that children receiving immediate treatment will have significantly lower anxiety scores than children assigned to the waitlist at the posttreatment/postwaitlist assessment. If results are favorable, further exploration of dissemination of CBT into school clinic settings may be indicated.
