The term cerebral palsy refers to any one of a number of neurological
disorders that appear in infancy or early childhood and permanently affect body
movement and muscle coordination but don’t worsen over time. Even though
cerebral palsy affects muscle movement, it isn’t caused by problems in the
muscles or nerves. It is caused by abnormalities in parts of the brain that
control muscle movements. The majority of children with cerebral palsy are born
with it, although it may not be detected until months or years later. The early
signs of cerebral palsy usually appear before a child reaches 3 years of age.
The most common are a lack of muscle coordination when performing voluntary
movements (ataxia); stiff or tight muscles and exaggerated reflexes
(spasticity); walking with one foot or leg dragging; walking on the toes, a
crouched gait, or a “scissored” gait; and muscle tone that is either too stiff
or too floppy. A small number of children have cerebral palsy as the result of
brain damage in the first few months or years of life, brain infections such as
bacterial meningitis or viral encephalitis, or head injury from a motor vehicle
accident, a fall, or child abuse.
Cerebral palsy can’t be cured, but treatment will often improve a child's
capabilities. In general, the earlier treatment begins the better chance
children have of overcoming developmental disabilities or learning new ways to
accomplish the tasks that challenge them. Treatment may include physical and
occupational therapy, speech therapy, drugs to control seizures, relax muscle
spasms, and alleviate pain; surgery to correct anatomical abnormalities or
release tight muscles; braces and other orthotic devices; wheelchairs and
rolling walkers; and communication aids such as computers with attached voice
synthesizers.
