N-Acetylcysteine for Nonsuicidal Self-Injurious Behavior in 3 Adults With Williams Syndrome

Le résumé fourni par la source

BACKGROUND: Williams syndrome (WS) is a genetic disorder that results from a microdeletion of 25 to 27 genes on chromosome 7q11.23. Individuals with WS often exhibit comorbid neuropsychiatric symptoms, especially anxiety. To our knowledge, nonsuicidal self-injurious behavior (NSSIB) has not been reported in WS. N -acetylcysteine (NAC) is a safe and readily available drug that may modulate glutamate activity in the brain. NAC is effective for treating various neuropsychiatric symptoms and disorders. There are limited reports in the literature where NAC has been used to treat NSSIB effectively, but none in WS. METHODS: This report describes using NAC to treat NSSIB in 3 adults with WS. FINDINGS: Nonsuicidal self-injurious behavior was successfully treated in 3 adults with WS using NAC in doses ranging from 2400 to 3600 mg a day, resulting in significant improvement in their daily functioning. Additionally, NAC was well tolerated. CONCLUSIONS: NAC was effective for treating NSSIB in 3 adults with WS. By addressing these challenging behaviors, NAC offers a promising pharmacological intervention that can significantly improve the quality of life for patients with WS who engage in NSSIB. Further research and clinical trials are necessary.
