A Young Man with Trisomy 21 and Sudden Behavioral Changes.

Area of Science:

• Neurodevelopmental disorders
• Behavioral science
• Genetics

Background:

• Trisomy 21 (Down syndrome) is associated with a range of developmental and behavioral characteristics.
• Behavioral challenges in individuals with intellectual disabilities can be exacerbated by environmental and medical changes.

Observation:

• A 13-year-old male with trisomy 21 presented with new disruptive behaviors including spitting, self-injury, and inappropriate behaviors.
• Recent stressors included a change in residential school placement, dental work under anesthesia, and discontinuation of an alpha-agonist medication.
• The patient's previous episode of behavioral challenges was successfully managed with increased supports and communication optimization.

Findings:

• The emergence of disruptive behaviors in Grant is temporally associated with significant educational and medical changes.
• Potential contributing factors include the transition to a new school environment, dental procedures, and medication changes.
• Grant's history suggests a positive response to tailored behavioral and communication interventions.

Implications:

• Environmental and medical factors significantly influence behavioral outcomes in individuals with trisomy 21.
• A comprehensive assessment is crucial to identify triggers for behavioral changes.
• Optimizing augmentative communication and behavioral supports can effectively manage challenging behaviors.
