Real-Life Examples of Intellectual Disability: Case Studies

📚 Quick Study Guide

• 🧠 Definition: Intellectual disability (ID) involves significant limitations in both intellectual functioning and adaptive behavior, originating before age 18.
• 📝 Assessment: Diagnosis requires standardized testing of intellectual functioning (IQ score typically below 70) and adaptive behavior assessments.
• 🌍 Adaptive Behavior: Includes conceptual, social, and practical skills. Deficits in these areas impact daily life.
• 🧬 Causes: Can be genetic (e.g., Down syndrome, Fragile X syndrome), prenatal (e.g., infections, exposure to toxins), perinatal (e.g., birth asphyxia), or postnatal (e.g., head trauma, infections).
• 💡 Levels of Severity: Classified as mild, moderate, severe, or profound, based on adaptive functioning and IQ scores.
• 🤝 Support: Individuals with ID benefit from individualized support plans focusing on education, vocational training, and community integration.
• 🌱 Early Intervention: Early intervention services are crucial for maximizing developmental potential.
