Deaf-blindness is a combination of vision and hearing loss, not necessarily
complete deafness and complete blindness. There is a wide range of thinking
and developmental ability among deaf-blind individuals from gifted to profoundly
multiply handicapped. Deaf-blindness creates additional problems in the
areas of mobility and communication, as well.
Estimates indicate that there are approximately 40,000 people in the United
States who are deaf-blind. A study by Teaching Research Division at Western
Oregon State College has identified over 5,000 children and youth. lt is
estimated that this number could be as high as 11,000. It is generally believed
that dual sensory impairment occurs in three of 100,000 births. There are
many causes of deaf-blindness; Rubella, CHARGE Association, Usher's Syndrome,
genetic disorders, accident and illness are some of the more common ones.
Federal legislation defines childen with deaf-blindness as individuals between
the ages of birth and 21 years of age who have "auditory and visual
impairments, the combination of which creates such severe communication
and other developmental and learning needs that they cannot be appropriately
educated without special eduction and related services, beyond those that
would be provided solely for children with hearing impairments, visual impairments, or severe disabilities, to address their educational needs due to those concurrent disabilities."
Individuals who are deaf-blind need early intervention and personal attention
to stimulate their understanding and interest in the world around them.
The information that most children pick-up naturally must be deliberately
introduced to children with dual sensory impairments.
Communication and mobility are often the most affected areas of life for
a person with deaf- blindness causing feelings of isolation and loneliness.
Development of compensatory skills can help bridge this gap. Trainings and
instructional strategies are available to parents and educators relative
to communication and mobility. Upon request California Deaf-Blind Services
provides assistance to families and schools to address individual needs.
Adapted from Deaf-Blindness: A Fact Sheet, Gallaudet University.
Fact sheets from California Deaf-Blind Services are to be
used by both families and professionals serving individuals with dual sensory
impairments. The information applies to students 0-22 years of age. The
purpose of the fact sheet is to give general information on a specific topic.
More specific information for an individual student can be provided through
individualized technical assistance available from CDBS. The fact sheet
is a starting point for further information.
