Brief Summary:
In the present study, we examine the question "Will day-time aggression in children improve when their night-time sleep is treated with pharmacological intervention (i.e. clonidine)?" There is considerable anecdotal evidence that clonidine may provide an effective alternative to neuroleptics for treating aggression in children -- first by improving the overall quality of their sleep, and second by providing a safer and more readily tolerated medication with fewer side-effects and a greater probability of long-term compliance. This study uses a double blind placebo controlled design to gather scientific evidence that will help elucidate the mechanisms underlying this treatment effect and will help clarify the relationship between sleep disorders and aggression in children. Our results are expected to help physicians make informed treatment decisions regarding the use of clonidine to improve the quality of sleep and possibly treat problems with aggression in their pediatric patients
Detailed Description:
Background: Childhood sleep disturbance is pervasive, yet remains under-treated and one of the most poorly researched areas in pediatric psychopharmacology. Of particular concern is the growing evidence of an association between sleep disturbance and aggression in children. Childhood aggression is a serious public health problem and predicts adolescent delinquency, academic difficulties and truancy, and substance abuse. Children with Tourette's syndrome (TS) and co-morbid attention deficit hyperactivity disorder (ADHD) will be studied in a trial of a common pharmacological treatment (clonidine) that is expected to improve sleep architecture and thereby clarify the relation between sleep disturbance and aggression.
Hypothesis: Our main hypothesis is that improvement in children's sleep will be associated with a reduction in their aggression and an increase in their daily function.
Method: A double-blind placebo controlled trial with 32 subjects (aged 9-14 years) with diagnoses of TS \& co-morbid ADHD. Subjects will undergo a mental health assessment, ECG, laboratory testing and 2-night polysomnography (sleep study) at baseline. Subjects will then be randomized to a treatment (clonidine) or placebo group for an 8-week trial. Clonidine will be titrated and subjects monitored weekly. A second 2-night sleep study and mental health assessment will occur at trial end.
Expected results: We expect an improvement in the initial onset, duration and overall sleep quality in the treatment group (clonidine), with a resulting decrease in daytime aggression and increase in daily overall level of functioning; sleep and aggression in the placebo group are not expected to improve.
