What is cerebral palsy?
Cerebral palsy (CP) is a neurological condition or group of conditions that affects gross motor skills, movement, muscle control, posture and coordination. CP is the result of damage to the brain and the most common cause of childhood disability; however, the disabilities can range from very mild to severe.
The effects of cerebral palsy vary from person to person, and many also have visual, learning or other impairments. There isn’t a cure, but with proper care and treatment from different specialists, most people with CP live as long as people without it. That’s why early diagnosis of cerebral palsy is so important. CP does not get worse over time but symptoms might change.
Cerebral palsy symptoms
Cerebral palsy symptoms are different for each person but typically include problems with development, movement and coordination. Symptoms usually appear in infancy or early childhood and can include:
- Delays in reaching motor skills milestones, such as:
- Persistent lag in holding up the head beyond 4 months old
- Keeping hands in fists (instead of opened) beyond 4 months old
- Not sitting without support after 9 months old
- Stiff or tight muscles – for example, stiffness or tightness in legs that develops between 6 and 12 months old
- Irregular body movement or posture such as:
- Consistent differences in posture or movement on one side of the body beyond 4 months old
- Definite hand preference before 12 months old
- Floppy muscle tone
- Tremors or involuntary movements
- Weakness in one or more limbs
- Seizures
- Intellectual or learning disabilities
- Feeding issues
If you have questions or concerns about your child’s development, always talk with your child’s doctor. Sometimes the symptoms of CP are obvious, and sometimes they are not. Sometimes what looks like CP is a symptom of something else. A trained health care provider can order tests to determine if your child has cerebral palsy. Earlier diagnosis means earlier intervention and treatment, which can improve long-term outcomes for children with CP.
Causes of cerebral palsy
CP is caused by a problem with the brain. It could be damage or improper development, and it generally happens before or around birth. Certain factors can affect brain development and increase the risk of CP. These can be separated into two groups:
Risk factors associated with pregnancy:
- Previous stillbirths or miscarriages
- Maternal thyroid disease
- Pre-eclampsia
- Abnormalities of the placenta
- Maternal infection during pregnancy (for example, German measles or rubella, toxoplasmosis, Zika virus)
- Substance use
- Multiple births (twins/triplets/quadruplets)
Risk factors identified at or around birth:
- Born prematurely
- Admitted to a neonatal intensive care unit (NICU)
- Lack of oxygen (neonatal encephalopathy) involving seizures and resuscitation
- Birth defects of the brain, heart or limbs
- Born too small for gestational age (growth restriction during pregnancy)
- Stroke/bleeding in the brain
- Infection of the spinal cord or brain
Cerebral palsy diagnosis
Your child’s doctor can diagnose CP with a combination of tests and assessments. The earlier CP is diagnosed, the sooner interventions and treatments can start. This improves long-term outcomes for children with CP. Your child’s doctor will review his or her medical history, evaluate motor skills and might recommend specific tests. Those tests might include:
- MRI
- Cranial ultrasound
- Electroencephalogram (EEG)
- Specialized assessments (such as speech, hearing or vision)
- Lab work
Our Cerebral Palsy Care Pathway program promotes early evaluation of babies and children at risk for CP. An early and accurate diagnosis allows access to appropriate interventions and resources for the child.
Cerebral palsy treatment
Cerebral palsy can’t be cured, but the symptoms and associated medical problems can be treated. Treatment is different for every patient and depends on their specific needs, and most patients with CP will see multiple specialists throughout their childhood. Coordinating care, such as the Cerebral Palsy Care Pathway, is important and some patients may need lifelong care.
Early intervention and treatment helps children maximize their ability to be as active and independent as possible. The patient’s needs may change over time, and the patient, family members and care team will update the treatment as needed.
Treatment options can include:
- Speech therapy
- Physical therapy
- Occupational therapy
- Medications
- Surgery
- Recreational therapy
- Assistive devices
