Intellectual and Developmental Disabilities

Intellectual and Developmental Disabilities

Adolescents and adults with intellectual and developmental disabilities (IDD) have diverse communication, cognitive, and swallowing needs that evolve across the lifespan. Speech-language pathology services focus on supporting independence, self-advocacy, safety, and meaningful participation at home, school, work, and in the community.

Therapy is individualized, strengths-based, and respectful of each person’s goals, preferences, and communication style.

Common Areas of Support

Communication and Language Differences
Individuals with IDD may experience challenges with:

  • Expressing wants, needs, thoughts, and emotions

  • Understanding spoken or written information

  • Social communication and pragmatic skills

  • Initiating or maintaining conversations

  • Using language effectively in real-world situations

Communication needs may change with increased life demands, transitions, or changes in support systems.

Cognitive and Executive Functioning Skills
Cognition supports daily independence and may impact:

  • Attention and task completion

  • Memory and following routines

  • Problem solving and decision making

  • Organization, planning, and time management

  • Safety awareness and judgment

These skills are essential for navigating daily life, employment, healthcare, and community participation.

Swallowing and Feeding Needs (Dysphagia)
Swallowing differences are more common in individuals with IDD and may be influenced by muscle tone, coordination, sensory differences, posture, medications, or medical comorbidities. Challenges may include:

  • Difficulty chewing or managing textures

  • Fatigue during meals

  • Coughing or choking

  • Rapid eating or reduced awareness of bolus size

  • Increased risk of aspiration

Swallowing needs may change over time and require ongoing monitoring and support.
