Insights
A rare 1q21.3 microdeletion in a nonverbal autistic boy with intellectual disability led to severe self-injurious behaviors and developmental regression. Multidisciplinary inpatient care, pain management, and tailored therapies significantly reduced self-harm and improved development.
Area of Science:
- Neurodevelopmental disorders
- Genetics
- Behavioral science
Background:
- Autism spectrum disorder (ASD) and intellectual disability (ID) can present with complex behavioral challenges.
- Rare genetic microdeletions, such as 1q21.3, are increasingly recognized as contributing factors to neurodevelopmental phenotypes.
- Self-injurious behaviors (SIB) in individuals with severe developmental disabilities pose significant clinical challenges and can lead to secondary complications like blindness.
Observation:
- A young boy with nonverbal autism and intellectual disability was diagnosed with a de novo 1q21.3 microdeletion.
- The patient exhibited early-onset, extreme self-injurious behaviors resulting in blindness and severe developmental regression.
- Conventional interventions were insufficient to manage the severity of the SIB and regression.
Findings:
- A multidisciplinary neurodevelopmental inpatient approach led to a significant reduction in self-injurious behaviors.
- Addressing underlying somatic pain through opiate blockers and mood stabilization was crucial for behavioral improvement.
- Sensorimotor developmental approaches, including therapeutic body wraps, and blindness-adapted psychoeducation facilitated communication gains.
Implications:
- This case highlights the complex interplay between genetic factors, severe behavioral phenotypes, and neurodevelopmental trajectories.
- Multidisciplinary, inpatient management targeting somatic pain, mood, and sensory-motor needs can effectively mitigate severe SIB and developmental regression in rare genetic disorders.
- Tailored therapeutic strategies, including adapted communication methods, are essential for improving quality of life in individuals with complex neurodevelopmental profiles and acquired disabilities.
Abstract:
We report the case of a young boy with nonverbal autism and intellectual disability, with a rare de novo 1q21.3 microdeletion. The patient had early and extreme self-injurious behaviours that led to blindness, complicated by severe developmental regression. A significant reduction in the self-injurious behaviours and the recovery of developmental dynamics were attained in a multidisciplinary neurodevelopmental inpatient unit. Improvement was obtained after managing all causes of somatic pains, using opiate blockers and stabilizing the patient's mood. We offered both sensorimotor developmental approach with therapeutic body wrap and specific psychoeducation adapted to his blindness condition for improving his communication abilities.
