| IDEA defines DEAF-BLINDNESS as "concomitant hearing and vision impairments, the combination of which causes such severe communication and other developmental and educational needs that they cannot be accommodated in special education programs solely for children with deafness or children with blindness." |
| The concomitant vision and hearing difficulties (sometimes referred to as dual sensory impairments) exhibited by people with deaf-blindness result in severe communication deficits as well as developmental and educational difficulties that require extensive support across several professional disciplines. The impact of both vision and hearing loss on the educational needs of the student is a matter of debate among professionals. One view of deaf-blindness is that individuals have such severe intellectual disability that both vision and hearing are also affected. Another view is that they have average intelligence and lost their hearing and sight after they acquired language. Intellectual functioning for persons with deaf-blindness may range from normal or gifted to severe intellectual disability (just like everyone else). All people with deaf-blindness experience challenges in learning to communicate, access information, and comfortably move through their environments. These individuals may also have physical and behavioral disabilities. However, the specific needs of each person will vary enormously according to age, onset, and type of deaf-blindness. |
| PREVALENCE of DEAF-BLINDNESS In 2003-2004 school year, the Department of Education reported that 1,667 students between the ages of 6 and 21 were given special education in this category. This accounts for 0.03% of the students with disabilities served under IDEA. |
| Touch is a reciprocal sense. Positive touch promotes health and well-being. People who relate to children who are deaf/blind need to become especially conscious of how they use touch. Tactile sensitivity can be the result of touch experiences or it can be related to neurological conditions and especially sensitive nervous systems. Children who are deaf/blind use their hands as tools, eyes, ears, and voice and also to relieve stress. Touch can be a basis for genuine conversations with a child who is deaf/blind. The gestures that children make to reach out and explore are actually the beginning of mobility. Children who are deaf/blind need access to others' hands. Children who are deaf/blind usually need to learn language through touch or at least with touch as a strong support. Even children who have significant amounts of vision and hearing can greatly benefit from touch as a support to these senses and to help these children focus. |
