Trial Summary

What is the purpose of this trial?

The goals of this clinical trial are to identify factors associated with the development of problem behavior in Cornelia de Lange syndrome (CdLS) and to develop an effective behavioral assessment and treatment model for problem behavior in children with CdLS. The hypotheses are as follows: 1. Based on pilot data, the investigators hypothesize that individuals with CdLS will exhibit preferences for auditory stimuli relative to other categories (e.g., visual, tactile) of stimuli. 2. Based on pilot data, the investigators hypothesize that individuals with CdLS will exhibit problem behavior to obtain adult attention or to escape task demands relative to tangible and control conditions, as measured by functional analysis results. 3. Function-based behavioral treatments will reduce problem behavior in individuals with CdLS by 80% or greater relative to baseline rates. 4. Individuals with CdLS and problem behavior will exhibit more impaired communication, demonstrate increased emotion dysregulation, and exhibit more severe symptoms of Autism Spectrum Disorder (ASD) relative to those with CdLS and no problem behavior. Participants in the intervention group (families of children with CdLS and problem behaviors) will be asked to complete study measures and attend 2 full days and one half-day of clinic services at Kennedy Krieger Institute so that the study team can provide assessment and treatment of child problem behaviors, and then train parents to apply the intervention. Participants in the control group (families of children with CdLS and no problem behavior) will be asked to complete study measures once every 3 months for a 2-year period to monitor the children. This study will improve the ability to effectively treat problem behavior is CdLS, as well as identify key variables associated with problem behavior in CdLS which may be examined in future studies and clinical practice to foster early intervention and prevention efforts.

Will I have to stop taking my current medications?

The trial information does not specify whether participants need to stop taking their current medications.

What data supports the effectiveness of this treatment for Cornelia de Lange Syndrome?

While there is no direct evidence from the provided research about the effectiveness of ABA-based therapy for Cornelia de Lange Syndrome, ABA therapy has been shown to be effective in managing similar behavioral issues in other conditions, such as autism spectrum disorders, which share some behavioral characteristics with Cornelia de Lange Syndrome.12345

Is behavioral therapy, like ABA, safe for people with developmental disabilities?

The research does not specifically address safety concerns for ABA therapy, but it is widely used for various developmental disabilities, suggesting it is generally considered safe. However, always consult with a healthcare provider for personalized advice.678910

How does ABA-based functional analysis and treatment differ from other treatments for Cornelia de Lange Syndrome?

ABA-based functional analysis and treatment is unique because it focuses on understanding and modifying behavior through structured interventions, such as identifying the reasons behind problem behaviors and teaching alternative communication methods. This approach is different from other treatments that may not specifically target the behavioral aspects of Cornelia de Lange Syndrome.711121314

Eligibility Criteria

This trial is for English-speaking parents of children aged 3-15 with Cornelia de Lange syndrome (CdLS). It includes those whose children exhibit self-injurious behavior, aggression, or disruptive behavior and can attend clinic visits. Children without these behaviors are in the control group.

Inclusion Criteria

I am an English-speaking parent of a child with CdLS and willing to complete study measures.
I am an English-speaking parent of a child with CdLS, willing to attend clinic visits, complete study tasks, and follow a behavior plan.

Exclusion Criteria

Children with CdLS in the treatment group should not show certain behaviors, be younger than 3 or older than 15, or require extensive medical care that could affect participation. Also, parents of these children should be willing to complete study procedures and be able to speak English.

Treatment Details

Interventions

  • ABA-based functional analysis and treatment
Trial Overview The study tests a behavioral assessment and treatment based on Applied Behavior Analysis (ABA) for managing problem behaviors in kids with CdLS. The goal is to reduce such behaviors by at least 80% using function-based treatments.

Findings from Research

In a study of 49 individuals with Cornelia de Lange syndrome, a significant number exhibited behavioral challenges, including sleep disturbances (55%), daily aggression (49%), and self-injury (44%), highlighting the need for tailored support.
The presence of these behavioral issues correlated with the severity of mental retardation and the occurrence of autistic-like symptoms, indicating that the degree of cognitive impairment may influence the behavioral phenotype and support requirements throughout life.
Behavioural phenotype of Cornelia de Lange syndrome.Berney, TP., Ireland, M., Burn, J.[2022]
In a 7-year follow-up study of 30 individuals with Cornelia de Lange syndrome, there was an observed increase in the proportion of individuals meeting criteria for autism spectrum disorder, indicating complex changes in behavior over time.
Despite these behavioral changes, both Cornelia de Lange and Cri du Chat syndrome groups showed stable levels of adaptive ability and improvements in receptive language, suggesting that overall abilities did not decline during the study period.

In a study of 56 individuals with Cornelia de Lange Syndrome (CdLS), common behavioral characteristics such as hyperactivity, anxiety, and autistic-like features were identified, highlighting the complexity of the syndrome's behavioral profile.
The variability in behavioral traits was linked to clinical factors like age and cognitive level, suggesting that CdLS may encompass multiple behavioral phenotypes that differ significantly among individuals.
