Cerebral palsy (CP) is a group of chronic disorders that affect the ability to control movement. It appears in the first few years of life. Generally, the nerve damage does not worsen over time, but the muscle, joint, and skeletal effects can get worse without treatment.
CP occurs due to damage to areas of the brain that direct movement. This damage interferes with the brain's ability to control movement and posture. Other areas of the brain controlling thinking, speech, vision, or hearing may also be involved. CP may develop before, during, or after birth.

- There are abnormalities of the umbilical cord or placenta, or the placenta separates too early from the wall of the uterus

encephalitis, seizures, or head injury
- Child has genetic/metabolic abnormalities
- Brain tissue that may not develop correctly during pregnancy—growing fetus may experience a lack of oxygen or nutrients
- Mother has rubella, toxoplasmosis, or cytomegalovirus while pregnant
- Mother and child's blood types are not compatible causing severe jaundice
Factors that increase the risk of CP include:
- Low birth weight
- Complicated or premature delivery
- Multiple births, such as twins or triplets
- Breech birth
In vitro fertilization (IVF)—in part due to multiple births associated with IVF
- Infection or blood clotting problems during pregnancy
- Vaginal bleeding during pregnancy
- Family history of CP in parent or sibling
- Seizures or

- Low Apgar score—a rating of the child's condition just after birth
- Vaginal or urinary tract infection during pregnancy
- High birth weight

- Obesity in the expectant mother
- Small head
Symptoms of CP vary widely. They may include difficulty with fine motor tasks like writing or using scissors, difficulty maintaining balance or walking, difficulty hearing or speaking, muscle tightness, and involuntary movements . The symptoms differ from person to person and may change over time.
CP first shows up in children aged 3 years or younger. Symptoms vary depending on what areas of the brain are affected. The problems can involve one side of the body (hemiplegia), the upper or lower body (diplegia), or both the upper and lower body on both sides (quadraplegia). Occasionally the face and neck are involved.
Disabilities can be mild to severe and vary from side to side and top to bottom. Although symptoms may change or progress slightly as the child grows older, the child's condition is unlikely to worsen significantly, especially with treatment.
- Late to turn over, sit up, smile, or walk
- Trouble writing, buttoning a button, or other fine motor activities
- Difficulty walking or standing
- Tight, spastic muscles
- Weak muscles
- Poor balance
- Speech problems
- Unintentional body movements
- Difficulty swallowing
Some people with CP suffer from other medical disorders as well, including:
- Intellectual disability
- Learning disabilities
- Decreased ability to feel pain or identify items by touch
- Problems with bowel and bladder control
- Breathing problems if food or water has accidentally entered the lungs
- Skin breakdown
Low bone density and
Doctors diagnose CP by testing motor skills and reflexes, looking into medical history, and using a variety of specialized tests.

There is no treatment to cure CP. The brain damage cannot be corrected. Therapy aims to help the child reach his or her full potential. Children with CP grow to adulthood and may be able to work and live independently.
Drugs help control muscle spasms and seizures, and prevent bone loss.
Medications may help:
Different seizure medications can be used depending on the type of seizure
Certain operations may improve the ability to sit, stand, and walk. These may include tendon transfers or lengthening, joint loosening, bone straightening, and nerve surgery.
Braces and splints help reduce muscle contraction, keep limbs in correct alignment, and prevent deformities. Positioning devices enable better posture.
Walkers, special scooters, and

Programs designed to meet the child's special needs may improve learning. Some children do well attending regular schools with special services. Vocational training can help prepare young adults for jobs.
Speech, physical, and occupational therapies may improve the ability to speak, move, walk, and perform activities of daily living. Physical therapy helps strengthen muscles and improve fitness. Children can learn different ways to complete difficult tasks.

Therapeutic electrical stimulation might help increase muscle strength and range of motion.
Several of the causes of CP that have been identified through research are preventable or treatable:
Before getting pregnant, receive a
- Seek early prenatal care.
- Receive testing for blood-type problems when pregnant. Get treatment if tests reveal incompatible blood types.
alcohol, or use drugs while pregnant.
- Put the baby in a child safety seat when in the car.
- Insist that the child wear a helmet when riding a bicycle.
- Seek help if you have, or want to, hurt the child.
- Keep poisons away from your child.
- Closely supervise bathing.
Get your child
at the recommended time.
- If your baby becomes sick, call the doctor right away.
- For infants with brain injury at birth, hypothermia to lower body temperature can reduce the risk of tissue injury and of long-term problems.
