Behavioral disturbance and treatment strategies in Smith-Magenis syndrome

Behavioral disturbance and treatment strategies in Smith-Magenis syndrome

BACKGROUND Smith-Magenis syndrome is a complex neurodevelopmental disorder that includes intellectual deficiency, speech delay, behavioral disturbance and typical sleep disorders. Ninety percent of the cases are due to a 17p11.2 deletion encompassing the RAI1 gene; other cases are linked to mutations of the same gene. Behavioral disorders often include outbursts, attention deficit/hyperactivity...

Sleep Disturbance in Smith-Magenis Syndrome

Smith-Magenis syndrome (SMS) is a clinically recognizable multiple congenital anomaly and mental retardation syndrome caused by an interstitial deletion of chromosome 17 p11.2. Although the physical and molecular genetic features of SMS are increasingly well understood, work is more limited on SMS’s behavioral phenotype, which includes self-injury, tantrums, and sleep disturbance. This study ex...

Intellectual and Behavioral Disabilities in Smith — Magenis Syndrome

Behavioral phenotype of Smith-Magenis syndrome (del 17p11.2).

Smith-Magenis syndrome (SMS) is a distinct and clinically recognizable multiple congenital anomaly (MCA) and mental retardation syndrome caused by an interstitial deletion of chromosome 17 p11.2. The phenotype of SMS has been well described and includes: a characteristic pattern of physical features; a hoarse, deep voice; speech delay with or without associated hearing loss; signs of peripheral...

Pharmacological treatment of disruptive behavior in Smith-Magenis syndrome.

Smith-Magenis syndrome (SMS) is a complex genetic syndrome caused by an interstitial deletion of chromosome 17p11.2. Children and adults with SMS appear to have unique neurobehavioral problems that include: sleep disturbance, self-injurious and maladaptive behaviors, stereotypies, and sensory integration disorders. We gathered retrospective psychotropic use information from parents or other car...
