简要总结
Over 10% of children in the United States are diagnosed with ADHD, and nearly half of these children have moderate to severe impairments in sleep, further exacerbating their already impaired academic, emotional and social functioning. In children with ADHD, 34% of prescribed sleep medications are antipsychotics that can cause marked weight gain and metabolic changes; alternate medications have either been found to be ineffective, difficult to tolerate or are largely unstudied in youth. Delayed sleep onset is strongly correlated with active symptoms of ADHD and Oppositional Defiant Disorder (ODD), suggesting that better control of disruptive behaviors could improve sleep patterns and this application will assess if the extension of the therapeutic effects of CNS stimulants into the early evening improves sleep onset.
详细描述
The goal of this application is to assess the impact of safer treatment option Methylphenidate (MPH) on sleep and behavior problems in children with Attention Deficit Hyperactivity Disorder (ADHD) and Behavioral Insomnia of Childhood (BIC). ADHD affects over 11% of school-aged youth. Similarly, pediatric sleep disorders occur in over a third of children and impact multiple domains of the child's functioning as well as that of their parents. Children with ADHD are at an increased risk for sleep problems with a staggering comorbidity of up to 70%, while sleep deprivation worsens the already impaired social, emotional and academic functioning of children with ADHD. Therefore, improving sleep may translate into enhanced functioning in multiple realms. Delayed sleep onset latency (SOL) and bedtime resistance, the key component of the limit setting type of BIC, are particularly likely to occur in children with ADHD. Medications are commonly used for both conditions with over 6% of all school-aged children in the United States prescribed medication for ADHD and 7% for sleep. In children with ADHD, 34% of prescribed sleep medications are antipsychotics that can cause marked weight gain and metabolic changes. Alternate medications for sleep have either been found to be ineffective, difficult to tolerate or are largely unstudied in youth. MPH has an extensive database supporting their safety and efficacy. Objective sleep studies of MPH have not found consistent results, with a few studies reporting delayed SOL and while others report improved quality of sleep. Therefore, this proposal will evaluate the impact of extending MPH treatment into the early evening on sleep onset using a 3-week with-in subjects randomized trial of .3mg/kg of immediate release (IR) MPH dosed 3 hours before bedtime vs. placebo in 38 children with ADHD and chronically delayed SOL who have a history of prolonged stimulant usage. The investigators will recruit 38 children ages 6-12 of any gender and racial/ethnic status with ADHD who have been treated with stable morning dose of extended release (ER) MPH for an extended time period (30 days or more) from the primary care and psychiatry clinics at Hershey Medical Center in Hershey, PA. Recruitment will be split into three waves (13, 13, 12 participants). Parents will be reminded to administer the blinded medication dose by text message each evening (or phone call by study staff) 3 hours prior to the desired bedtime. Sleep onset will be measured by actigraphy and sleep log, with parents also reporting on level of ODD and ADHD symptoms in the evening.

入选标准
- •Ages 6-12 (inclusive), and able to swallow capsule
- •Children who have been treated with a stable morning dose of Extended Release Methylphenidate or twice daily dose of Immediate Release Methylphenidate for an extended period of time (30 days or longer).
- •DSM V diagnosis of Attention Deficit Hyperactivity Disorder (ADHD): Diagnosis will be assessed on the NIMH Computerized Diagnostic Interview Schedule for Children (C-DISC), and parent and teacher rating scales.
- •Children with any ADHD subtype meeting the above criteria will be eligible, although, it is expected that the majority will be of the combined subtype of ADHD given the associate between this subtype and ODD symptoms. A diagnosis of any of the two Behavioral Insomnia of Childhood (BIC) subtypes associated with delayed SOL (limit setting or combined type) will be required.
- •Sex: male or female
- •Fluent in written and spoken English.
排除标准
- •Age < 6 years of age or >12 years of age.
- •Children who have not had Methylphenidate (Extended Release) treatment for an extended period of time (30 days or longer).
- •A diagnosis or suspicion of sleep-disordered breathing will be exclusionary as it is not expected to be impacted by Immediate Release Methylphenidate treatment.
- •Current psychotropics other than Methylphenidate (Extended Release or Immediate Release Methylphenidate). Children prescribed alpha agonists for adjunctive control of ADHD in combination with a MPH product will be allowed to enroll as long as they meet all other entry criteria (i.e. sleep must remained impaired with use of alpha agonist).
- •Regular use of other medications that impact sleep within the last 14 days (i.e.: sedating antihistamines, melatonin).
- •Active medical/psychiatric conditions that impact sleep (i.e.: severe asthma, Autism Spectrum Disorder diagnosis, marked developmental delay, or mood/anxiety disorder).
