This document discusses intellectual disabilities. It defines intellectual disabilities as limitations in intellectual functioning and adaptive behaviors that originate before age 18. Causes can include genetic syndromes, infections, trauma, and other medical conditions. People with intellectual disabilities may have difficulties with language, learning, concentration, behavior, and independent living. They benefit from supported education tailored to their needs, including adaptations to curriculum, assistive technology, life skills training, and opportunities for employment and social involvement. Teachers can help by using concrete examples, repetition, participation, and addressing different learning styles.
