a disability category in IDEA
Multiple Disabilities

Characteristics and Background Information:
Children with multiple disabilities will have a
combination of various disabilities that may include:
speech, physical mobility, learning, mental retardation,
visual, hearing, brain injury and possibly others. Along
with multiple disabilities, they can also exhibit sensory
losses and behavior and or social problems. Children
with multiple disabilities - also referred to as multiple
exceptionalities will vary in severity and characteristics.
These students may exhibit weakness in auditory
processing and have speech limitations. Physical
mobility will often be an area of need. These students
may have difficulty attaining and remembering skills and
or transferring these skills from one situation to
another. Support is usually needed beyond the confines
of the classroom. There are often medical implications
with some of the more severe multiple disabilities which
could include students with cerebral palsy and severe
autism and brain injuries. There are many educational
implications for these students.
MULTIPLE DISABILITIES

A cross-classification of disabilities that involves significant
physical, sensory, intellectual, and/or social-interpersonal
performance differences. The need for extensive services and
supports is evident in all environmental settings.

IDEA DEFINITION OF MULTIPLE DISABILITIES:
Concomitant impairments (such as mental
retardation-blindness or mental
retardation-orthopedic impairment), the
combination of which causes such severe
educational needs that they cannot be
accommodated in special education programs
solely for one of the impairments. Multiple
disabilities does not include deaf-blindness.
Cerebral Palsy

“Cerebral” means brain. “Palsy” means a disorder of movement. CP
refers to a group of non-progressive neuromuscular problems of
varying severity.

CP is damage to the brain, primarily to the part of the brain that
controls motor functions. However other parts of the brain may also
be affected. In such cases the person affected has more than one
disability.

The extent of the damage varies from person to person. Mild
disability might mean fine motor skills, like using scissors or writing,
are difficult. Severe disability can mean poor movement of all four
limbs, the trunk and neck. The child may even have difficulty in
swallowing.
Facts

~Cerebral Palsy means damage to the brain.
~Early diagnosis has the benefit of early
intervention strategies.
~Medications and surgery cannot cure this
condition.
~A youngster with cerebral palsy  generally has
more than one disability.
~Cerebral palsy is not hereditary
~Cerebral palsy is not contagious
~Cerebral palsy is not progressive
There are three major types of cerebral
palsy, and some  individuals may have
symptoms of more than one type.

Spastic cerebral palsy. About 70 to 80 percent
of affected individuals have spastic cerebral
palsy, in which muscles are stiff, making
movement difficult. When both legs are affected
(spastic diplegia), a child may have difficulty
walking because tight muscles in the hips and
legs cause legs to turn inward and cross at the
knees (called
scissoring). In other cases, only
one side of the body is affected
(spastic
hemiplegia)
, often with the arm more severely
affected than the leg. Most severe is
spastic
quadriplegia
, in which all four limbs and the
trunk are affected, often along with the muscles
controlling the mouth and tongue. Children with
spastic quadriplegia often have mental
retardation and other problems.

Athetoid or dyskinetic cerebral palsy. About
10 to 20 percent of affected individuals have the
athetoid form, which affects the entire body. It is
characterized by fluctuations in muscle tone
(varying from too tight to too loose) and
sometimes is associated with uncontrolled
movements (which can be slow and writhing or
rapid and jerky). Children often have trouble
learning to control their bodies well enough to
sit and walk. Because muscles of the face and
tongue can be affected, there also can be
difficulties with sucking, swallowing and speech.

Ataxic cerebral palsy. About 5 to 10 percent of
affected individuals have the ataxic form, which
affects balance and coordination. They may walk
with an unsteady gait with feet far apart, and
they have difficulty with motions that require
precise coordination, such as writing.
In about 70 percent of cases, cerebral palsy results from events
occurring before birth that can disrupt normal development of
the brain. Contrary to common belief, lack of oxygen reaching the
fetus during labor and delivery contributes to only a small
minority of cases of cerebral palsy.

Some of the known causes of cerebral palsy include:

Infections during pregnancy
. Certain infections in the mother,
including
rubella (German measles), cytomegalovirus (a usually
mild viral infection) and
toxoplasmosis (a usually mild parasitic
infection) can cause brain damage and result in cerebral palsy.
Recent studies suggest that maternal infections involving the
placental membranes (
chorioamnionitis) may contribute to
cerebral palsy in full-term as well as preterm babies (those born
before 37 completed weeks of pregnancy). A 2003 study at the
University of California at San Francisco found that full-term
babies were four times more likely to develop cerebral palsy if
they were exposed to chorioamnionitis in the womb.
Reproductive/urinary tract infections also may increase the risk
of preterm delivery, another risk factor for cerebral palsy.

Insufficient oxygen reaching the fetus. For example, when the
placenta is not functioning properly or it tears away from the wall
of the uterus before delivery, the fetus may not receive sufficient
oxygen.

Prematurity. Premature babies who weigh less than 3 1/3 pounds
are up to 30 times more likely to develop cerebral palsy than
full-term babies. Many of these tiny babies suffer from
bleeding
in the brain
, which can damage delicate brain tissue, or develop
periventricular leukomalacia, destruction of nerves around the
fluid-filled cavities (ventricles) in the brain.

Asphyxia during labor and delivery. Until recently, it was
widely believed that asphyxia (lack of oxygen) during a difficult
delivery was the cause of most cases of cerebral palsy. The
ACOG/AAP report shows that fewer than 10 percent of the type of
brain injuries that can result in cerebral palsy are caused by
asphyxia.

Blood Diseases. Rh disease, an incompatibility between the
blood of the mother and her fetus, can cause severe jaundice
and brain damage, resulting in cerebral palsy.  Rh disease usually
can be prevented by giving an Rh-negative woman an injection of
a blood product called Rh immune globulin around the 28th week
of pregnancy and again after the birth of an Rh-positive baby.
Blood clotting disorders (
thrombophilias) in either mother or
baby also may increase the risk.

Severe jaundice. Jaundice, yellowing of the skin and the whites
of the eyes caused by the build-up of a pigment called bilirubin in
the blood, occasionally becomes severe. Without treatment,
severe jaundice can pose a risk of permanent brain damage
resulting in athetoid cerebral palsy.

Other birth defects. Babies with brain malformations, numerous
genetic diseases
and other physical birth defects are at
increased risk of cerebral palsy.

Acquired cerebral palsy. About 10 percent of children with
cerebral palsy acquire it after birth due to brain injuries that
occur during the first two years of life. The most common causes
of such injuries are
brain infections (such as meningitis) and
head injuries.
