This document provides information about deafblindness and the unique needs of children who are deafblind. It defines deafblindness as the combination of hearing and vision impairments that prevents a child's needs from being met in programs for deaf or blind children alone. Children who are deafblind learn primarily through touch and require individualized attention and direct teaching to stimulate learning and development across areas like communication, movement, cognition, and social-emotional skills. The document outlines common causes of deafblindness and important intervention strategies to support deafblind children, such as communication methods, orientation and mobility training, and individualized education programs.
