Open-Label Study of N-Acetylcysteine in Children and Adolescents 5-17 With Bipolar Spectrum Disorders

• Status: Completed
• Trial end date: 2018-09-24
• Target enrollment: 0
• Participant gender: All

Summary

Children between the ages of 5-17 years old who have or display symptoms of emotional dysregulation (explosiveness, mood swings, irritability, and/or violent behavior) are invited to participate in a 12-week research study to determine the effectiveness and safety of the natural treatment N-acetylcysteine (NAC) for children with emotional and behavioral problems. After undergoing a comprehensive evaluation by medical doctors with a specialty in this area, children who are found eligible to participate in this research study will be treated with NAC. Following the evaluation period, this research study requires 12 weekly visits, either in our office or over the phone, in an effort to closely monitor each child's response to the medication. Eligible participants will receive study-related evaluations and weekly study visits with our study doctors at no cost.
