Filter by:The purpose of this study is to better understand the long-term progress of people with obsessive-compulsive disorder (OCD) and related conditions such as anorexia nervosa, Tourette syndrome, and trichotillomania. This study involves the screening and follow-up of individuals with OCD and OCD-related disorders. Participants will be screened with a medical and psychiatric evaluation, questionnaires, and neurological testing. Participants will then have study visits every 4 to 12 weeks to undergo symptom and daily functioning evaluations, personality tests, blood and urine tests, memory tests, brain scans, and other clinical exams. Participants will be assessed with interviews and paper-and-pencil or computer-assisted tests. Participants may have the opportunity to participate in drug studies and to join a monthly OCD support group. At the end of the study, participants will be referred to community or private treatment centers.
OBJECTIVES: I. Investigate the pathobiology of Tourette syndrome and related disorders by measuring various compounds of interest in cerebrospinal fluid, plasma, and urine of patients with Tourette syndrome, obsessive compulsive disorder, and/or chronic tics. II. Determine the pattern of familial aggregation of Tourette syndrome and obsessive compulsive disorder by systematic assessment of all first-degree family members of patients selected for cerebrospinal fluid studies. III. Establish the neurochemical and neuropeptide profile associated with the range of expression of the putative Tourette gene expression in adult and adolescent patients.
OBJECTIVES: I. Characterize the natural history, associated features, and severity of symptoms of obsessive compulsive disorder and Tourette syndrome in children and adolescents. II. Identify factors that influence the clinical course and prognosis of these patients.
Abnormalities in the re-uptake of dopamine and serotonin have been described in various neuropsychiatric disorders and substance abuse. [I-123] Beta-CIT is a recently developed radioligand for SPECT imaging of dopamine and serotonin transporters. [I-123]Beta-CIT SPECT has been used at the SPECT-lab of the Clinical Brain Disorders Branch in over fifty subjects without adverse events. Due to the trace concentrations used, a pharmacological effect of Beta-CIT is unlikely and has not been observed. The purpose of this study is to use Beta-CIT and SPECT to study the expression of dopamine and serotonin transporters in vivo in normal controls and various patient populations to address hypothesized abnormalities of the transporters in different disorders and to understand the effects of genetic variations in the genes of these transporters on their in vivo expression.
Bacteria carry substances on their surface called antigens. When antigens come into contact with the right kinds of cells in the body an immune reaction is caused. This reaction is often the symptoms of sickness that a patient feels. In order for the body to fight off the attack of antigens, it creates substances called antibodies. Antibodies counter the action of antigens and make the bacteria harmless. However, the immune system must learn how to make the right antibodies for the right antigens. Sometimes the body creates antibodies that confuse normal tissues as foreign and attack them. This is called an autoimmune reaction and sometimes occurs when the body is exposed to certain bacteria. One bacteria known for causing autoimmune reactions is Group A beta-hemolytic Streptococcus (GABHS). This bacteria often causes throat infections commonly known as "strep throat". Some researchers believe that the autoimmune reaction associated with strep throat infections may cause neuropsychiatric disorders, like obsessive-compulsive disorder and/or tic disorder in children. As a result, each time a child with one of these disorders experiences an infection with GABHS his/her symptoms can reoccur or worsen. Researchers believe that by giving patients a certain antibiotic, they can prevent GABHS infection and thus prevent the return of symptoms. This study is designed to test the effectiveness of the antibiotic Amoxicillin for the treatment of Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS). Patients will receive Amoxicillin for six weeks and placebos "inactive sugar pills" for six weeks in order to see if the medication is truly working. Effectiveness of the treatment will be based on the presence or absence of symptoms. If at the end of the study Amoxicillin is proven to be effective treatment for PANDAS patients may be offered the opportunity to continue taking the medication for an additional six months.
A subgroup of patients with childhood-onset obsessive-compulsive disorder (OCD) and/or tic disorders has been identified who share a common clinical course characterized by dramatic onset and symptom exacerbations following group A beta-hemolytic streptococcal (GABHS) infections. This subgroup is designated by the acronym PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections). There are five clinical characteristics that define the PANDAS subgroup: presence of OCD and/or tic disorder; prepubertal symptom onset; sudden onset or abrupt exacerbations (relapsing-remitting course); association with neurological abnormalities (presence of adventitious movements or motoric hyperactivity during exacerbations); and temporal association between symptom exacerbations and GABHS infections. In this subgroup, periodic exacerbations appear to be triggered by GABHS infections in a manner similar to that of Sydenham's chorea, the neurological variant of rheumatic fever. Rheumatic fever is a disorder with a presumed post-streptococcal autoimmune etiology. The streptococcal pathogenesis of rheumatic fever is supported by studies that have demonstrated the effectiveness of penicillin prophylaxis in preventing recurrences of this illness. A trial of penicillin prophylaxis in the PANDAS subgroup demonstrated that penicillin was not superior to placebo as prophylaxis against GABHS infections in these children, but this outcome was felt to be secondary to non-compliance with treatment, and there was no decrease in the number of neuropsychiatric symptom exacerbations in this group. In a study comparing azithromycin and penicillin, both drugs were completely effective in preventing streptococcal infections - there were no documented titer elevations during the year-long study period for children taking either penicillin or azithromycin. Comparable reductions in the severity of tics and obsessive-compulsive symptoms were also observed. Thus, penicillin was not performing as an "active placebo" as originally postulated, but rather provided effective prophylaxis against Group A beta-hemolytic streptococcal. Both azithromycin and penicillin appear to be effective in eliminating GABHS infections, and reducing neuropsychiatric symptom severity; thus, between-group differences are negligible. Since increasing the "n" to demonstrate superiority of one prophylactic agent over another would be impractical, we have amended the study design to address two issues: 1. To determine if antibiotics prophylaxis against GABHS infections is superior to placebo in prolonging periods of remission among children in the PANDAS subgroup. 2. To determine if antibiotics prophylaxis against GABHS infections is superior to placebo in improving overall symptom severity for obsessive-compulsive symptoms and tics among children in the PANDAS subgroup. Because penicillin has a narrower therapeutic index and is less expensive than azithromycin, it is the preferable prophylactic agent. Further, penicillin (250 mg orally twice a day) has a long history of providing safe and effective prophylaxis for rheumatic fever and is the first line oral therapy recommended by the American Heart Association. Thus, penicillin has been chosen as the prophylactic antibiotic in the present study. Blister packs are used to increase compliance and to allow for easier documentation of missed doses.
The purpose of this study is to see if it is effective to treat children with anxiety disorders with fluvoxamine. Fluvoxamine has been successfully used to treat obsessive-compulsive disorder (OCD) in adults and children. Anxiety disorders other than OCD, such as generalized anxiety disorder, social phobia, or separation anxiety, are very common in youth and are not always responsive to behavioral therapies alone. These disorders may respond to fluvoxamine. A child will be evaluated for 3 weeks before he/she is assigned randomly (like tossing a coin) to receive either fluvoxamine or an inactive placebo for 8 weeks. After this double-blind phase (neither the child/parents nor the doctor know which treatment is being given), the child will have the option of continuing treatment during a 4-month open-label extension period (both the child/parents and the doctor know which the child is receiving). A child may be eligible for this study if he/she: Is 6 to 17 years old and has been diagnosed with an anxiety disorder (i.e., generalized anxiety disorder, social phobia, or separation anxiety).
The purpose of this study is to evaluate a behavioral treatment program for children and adolescents with OCD and their families. Exposure and Response Prevention (ERP) behavior therapy, in which the patient is gradually exposed to the object or situation that causes anxiety and is taught to refrain from responding in a compulsive manner, is combined with family counseling (Family Treatment Program). This treatment will be compared to Relaxation Training (RT). OCD is a long-term, often disabling disorder that can cause significant family disruption. ERP is a promising treatment for children with OCD, and it is thought that family participation (through the Family Treatment Program) may be a helpful addition. RT is a common treatment for anxiety. Patients are assigned randomly (like tossing a coin) to receive either the ERP/Family Treatment Program or RT. Both treatments will be delivered over 12 90-minute outpatient sessions to youngsters and their families. All participants (patients and family members) will be assessed for treatment response each month during treatment, after treatment is finished, and then at 2 follow-up visits over the following 6 months. A child/adolescent may be eligible for this study if he/she: Has obsessive-compulsive disorder (OCD), is medication-free, and is 8 to 17 years old.
The purpose of this study is to compare 3 treatments for children with OCD: medication (sertraline, SER) alone vs OCD-specific therapy (Cognitive Behavior Therapy, CBT) vs medication plus therapy. Some patients will receive an inactive placebo (PBO) instead of medication and/or Educational Support (ES, non-psychological treatment) instead of therapy. One in 200 children suffer from OCD, but few receive appropriate treatment. Both CBT and medication seem to be effective, but their effectiveness, alone and in combination, has not been evaluated. There are 2 phases to this trial. In Phase I the child will receive 1 of the following 6 treatments for 12 weeks: 1) SER alone; 2) pill PBO alone; 3) CBT alone; 4) SER plus CBT; 5) SER plus ES; 6) pill PBO plus ES. If the child responds to treatment, he/she will go on to Phase II in which the treatment will be slowly reduced, then stopped (discontinued), over time to test the treatment's durability. The child will be evaluated at Weeks 1, 4, 8, 12 (Phase I treatment), and Weeks 16, 20, 24, and 28 (Phase II discontinuation) to see how effective and durable the treatment is in treating your child's OCD. A child may be eligible for this study if he/she: Has obsessive-compulsive disorder (OCD) and is 8 - 16 years old.
The purpose of this study is to find the best treatment for Tourette's Syndrome (TS)-spectrum obsessive-compulsive disorder (OCD), which includes symptoms of TS, e.g., repeated and involuntary body movements (tics). There are 2 parts to this study: In Part 1, patients are placed into 1 of 2 groups based on type of OCD, determined by medical history and family member interviews. In Part 2, patients are treated with fluvoxamine (FVX) for 8 weeks. If patients do not respond to FVX alone, either haloperidol or an inactive placebo will be added to the FVX regimen; patients will take this drug combination for 4 weeks. Patients will be monitored throughout the trial.
