Cerebral Palsy Introduction |
Cerebral Palsy
(CP) is a term used to describe a
number of chronic conditions
involving motor (physical) and brain
(neurological) function. Cerebral
Palsy is not a disease but a
life-long condition that affects the
communication between the brain and
the muscles, causing a permanent
state of uncoordinated movement and
posturing.[1]
There is not one
single cause but several triggering
factors that could contribute to the
manifestation of this disorder. It
was in the 1860's when the symptoms
of Cerebral Palsy were first
described; at that time the disorder
came to be known as Little's
disease. William Little, and
English surgeon, observed the stiff,
spastic leg movements of children as
they tried to grasp objects, and
attempt to walk and
crawl. He noticed that as these children grew
older, their condition didn't
improve or grow worse. What
was apparent in each child was the presence
of mental retardation, visual
disturbances and seizures. He
then suggested that depletion of oxygen
during birth was the cause of these
behaviors. Sigmund Freud,
however, disagreed and proposed there was
some other, notable event that occurred prior to
birth. "Difficult birth, in certain
cases," he wrote, "is merely a
symptom of deeper effects that
influence the development of the
fetus." [2]
Today, the cause of
cerebral palsy is still somewhat
elusive. Many different types of
brain injury can lead to cerebral
palsy, and many times an exact cause
cannot be determined. Birth injuries
and oxygen deprivation to the brain
before, during, and immediately
after birth, account for
approximately 10 to 15% of all cases. [3]
It has also been theorized that
because the first few years of
life are a more tenuous time for
infants, the threat and onset of severe illness,
inflammation, trauma or severe
dehydration could cause brain damage,
which may result in cerebral palsy. Other
risk factors include; premature
birth, low birth weight, blood type
incompatibility between mother and
child, lack of proper nutrients
during fetal development via the
placenta and absence of growth
factors during fetal development.[4]
The diagnosis of
cerebral palsy is difficult in early
infancy, due to many other
conditions that can have similar
presentation. As the child matures,
developmental milestones can be key indicators of poor coordination,
weakness and mental delay.
Typically, doctors diagnose cerebral
palsy in infants by testing their
motor skills, thoroughly analyzing
their medical history, and employing
some diagnostic tests such as
magnetic resonance imaging (MRI) or
computed tomography (CT) to discern
the nature of any brain damage and
help rule out other conditions.[5]
Because Cerebral
Palsy is an umbrella term for
several chronic conditions, its
manifestation depends on the
classification of the disorder. Symptoms can range from mild to
severe and thus cause varying
degrees of handicap. In all forms of
cerebral palsy there is difficulty
with annunciation of words, seeing
or hearing properly and behavioral
problems. Cerebral Palsy may be
grouped into 4 main groups,
depending on symptoms displayed and
other factors.
Spastic
-
Approximately 70% of children with cerebral palsy
have the spastic version.
-
Stiff and weak
muscles- can affect arms legs on one
side of both
-
Poorly developed
affected legs/arms
-
Mental retardation
(sometimes severe)
-
Seizures
-
Trouble swallowing
-
Choking on secretions
from mouth and stomach
-
Difficulty breathing
Choreoathetoid
-
Affects nearly 20% of children with
cerebral palsy
-
Spontaneous, slow muscle movement
-
Jerky abrupt movements
-
Symptoms better with sleep
-
Symptoms worse with strong emotions
-
Rarely have seizures
-
Usually have normal intelligence
Ataxic
-
About 10% of children with cerebral
palsy have the ataxic form
-
Poor coordination, shaky movements
-
Muscle weakness and trembling
-
Difficulty with rapid or fine
movements
-
Difficulty walking
Mixed

Cerebral Palsy Statistics |
-
About 764,000
children and adults in the United
States manifest one or more of the
symptoms of cerebral palsy.
-
Currently,
approximately 8,000 babies and
infants are diagnosed with the
condition every year.
-
1,200 - 1,500
preschool age children are said to
have cerebral palsy each year.[7]
