Learning Disabled
Autism
A developmental disability significantly affecting verbal and nonverbal
communication and social interaction, generally evident before age
3, that adversely affects a child's educational performance. Other
characteristics often associated with autism are engagement in repetitive
activities and stereotyped movements, resistance to environmental
change or change in daily routines, and unusual responses to sensory
experience. The term does not apply if a child's educational performance
is adversely affected primarily because the child has an emotional
disturbance as defined previously. A child who manifests the characteristics
of autism after age three could be diagnosed as having autism if the
criteria in this definition are satisfied.
Hearing Impairment
An impairment in hearing, whether permanent or fluctuating, that
adversely affects a child's educational performance but that is not
included under the definition of "deafness".
Orthopedic Impairment
A severe orthopedic impairment that adversely affects a child's
educational performance. The term includes impairments caused by congenital
anomaly (e.g., club foot, absence of some member), impairments caused
by disease (e.g., poliomyelitis, bone tuberculosis, etc,), and impairments
from other causes (e.g., cerebral palsy, amputations, and fractures
or burns that cause contractures).
Traumatic Brain Injury
An acquired injury to the brain caused by an external physical
force, resulting in total or partial functional disability or psychological
impairment, or both, that adversely affects a child's educational
performance. The term applies to open or closed head injuries resulting
in impairments in one or more areas, such as cognition, language,
memory, attention, reasoning, abstract thinking, judgment, problem-solving,
sensory, perceptual and motor abilities, psychological behavior, physical
function, information processing, and speech. The term does not apply
to brain injuries that are congenital or degenerative, or brain injuries
induced by birth trauma.
