Cerebral palsy is a neurological disorder affecting motor function, muscle tone, and coordination. Although it can’t be completely prevented, there are steps expectant mothers can take to reduce the risk of their child developing cerebral palsy.
This article will discuss the causes of cerebral palsy, ways to maintain a healthy pregnancy, and strategies to minimize risk factors during pregnancy and birth.
What are the chances of a baby having cerebral palsy?
The chances of a baby having cerebral palsy depend on various factors, such as the presence of risk factors during pregnancy and delivery. The overall prevalence of cerebral palsy is around 2-3 per 1,000 live births, which means that most babies are born without the condition.
However, the risk of cerebral palsy is higher in certain groups, such as premature babies and babies with low birth weight. Multiple births, maternal infections during pregnancy, and brain damage due to lack of oxygen during birth are also risk factors for cerebral palsy.
Additionally, some genetic mutations are associated with an increased risk of cerebral palsy. It is important to note that many children with these risk factors do not develop cerebral palsy, and some children without them can still develop the condition. Early identification and appropriate management of cerebral palsy can improve outcomes for affected individuals.
Types of Cerebral Palsy
Cerebral palsy is classified into four main types:
Spastic cerebral palsy is the most common type, affecting about 70-80% of individuals with cerebral palsy. It is characterized by muscle stiffness and difficulty moving, which can affect one side of the body (unilateral spastic) or both sides (bilateral spastic). The stiffness in the muscles is caused by damage to the part of the brain that controls voluntary movement, leading to increased muscle tone or hypertonia. The muscles may feel tight, making movements jerky or difficult to initiate.
Dyskinetic cerebral palsy affects about 10-15% of individuals with cerebral palsy. It involves involuntary movements and poor muscle coordination, which can cause writhing, twisting, or repetitive movements. Dyskinetic cerebral palsy can be further classified into two subtypes: athetoid and dystonic. Athetoid dyskinetic cerebral palsy is characterized by slow, writhing movements that can affect the face, hands, and feet. Dystonic dyskinetic cerebral palsy involves sustained muscle contractions that cause twisting or abnormal postures.
Ataxic cerebral palsy is rare, affecting only about 5-10% of individuals with the condition. It affects balance and coordination, leading to a lack of control over voluntary movements. The cerebellum, responsible for coordinating movements and maintaining balance, is affected in ataxic cerebral palsy. Individuals with ataxic cerebral palsy may struggle with tasks requiring precise movements, such as writing, buttoning clothes, or using utensils.
Mixed cerebral palsy is a combination of the above types, and it can occur when damage to the brain affects different areas that control movement. For example, an individual with mixed cerebral palsy may have spasticity on one side of the body and dyskinetic movements on the other. The symptoms of mixed cerebral palsy can vary widely, depending on the extent and location of brain damage.
Causes of Cerebral
Palsy Cerebral palsy is caused by damage to the developing brain during pregnancy, birth, or shortly after birth. Factors that may contribute to the development of cerebral palsy include:
Genetic mutations are one of the causes of cerebral palsy. They can occur spontaneously or can be inherited from parents. Genetic mutations can affect the development and function of the brain, leading to cerebral palsy. Several genes are known to increase the risk of cerebral palsy, and their mutations can cause structural or functional abnormalities in the brain.
Maternal infections during pregnancy can also increase the risk of cerebral palsy in the baby. Certain viral and bacterial infections can cause inflammation in the developing brain, leading to damage and abnormalities. Examples of infections that can lead to cerebral palsy include rubella, cytomegalovirus, toxoplasmosis, and herpes simplex virus.
Severe jaundice is when the bilirubin levels in the baby’s blood are too high. This can cause a yellowing of the skin and eyes and lead to brain damage. High levels of bilirubin can cross the blood-brain barrier and cause damage to the basal ganglia, a part of the brain responsible for motor control. If the basal ganglia are damaged, it can lead to cerebral palsy.
Oxygen deprivation during birth is another known cause of cerebral palsy. When the baby’s brain does not receive enough oxygen during delivery, it can lead to brain damage, which can cause cerebral palsy. Oxygen deprivation can occur for various reasons, such as a problem with the umbilical cord or placenta or if the baby experiences prolonged labor.
Traumatic brain injury is a well-known cause of cerebral palsy. It can happen if the baby suffers a head injury during delivery or shortly after birth. Traumatic brain injury can cause bleeding, swelling, or damage to the brain, which can lead to cerebral palsy. Brain injuries can also occur due to medical errors, such as incorrect use of forceps or vacuum during delivery.

Prenatal Care and Prevention
Regular Prenatal Checkups
Regular prenatal checkups are crucial for detecting potential issues that could lead to cerebral palsy. Early detection allows for timely intervention and treatment, reducing the likelihood of brain damage.
Expectant mothers with pre-existing conditions like diabetes, hypertension, or thyroid disorders should work closely with their healthcare team to manage these conditions throughout pregnancy. Proper management reduces the risk of complications that could affect the developing fetus.
Adopting a healthy lifestyle is essential for reducing the risk of cerebral palsy. Expectant mothers should avoid smoking, alcohol, and drug use, as these substances can harm the developing fetus.
The occurrence of cerebral palsy can be heightened by infections during pregnancy. Expectant mothers should practice good hygiene, avoid contact with sick individuals, and stay up-to-date on vaccinations to minimize the risk of infections. Pregnant women should also consult their healthcare provider if they suspect an infection.
Having a well-balanced diet is essential for maintaining a healthy pregnancy. Expectant mothers should consume nutrient-rich foods like fruits, vegetables, whole grains, lean proteins, and dairy products. Prenatal vitamins, including folic acid and iron, are also essential for fetal development and reducing the risk of birth defects that could contribute to cerebral palsy.
Regular fetal monitoring, including ultrasounds and non-stress tests, can help identify potential baby growth and development issues. These tests can detect conditions that may increase the risk of cerebral palsy, allowing for early intervention and treatment.
Selecting a competent and experienced birth team is crucial for ensuring safe delivery. This includes obstetricians, midwives, and pediatricians with experience in managing high-risk pregnancies and potential complications.
Creating a comprehensive birth plan that includes potential interventions and emergency procedures can help minimize the risk of complications during delivery. This plan should be discussed with the birth team to ensure everyone is on the same page and prepared for unexpected events.
FREQUENTLY ASKED QUESTIONS
Does folic acid prevent cerebral palsy?
There is no conclusive evidence to suggest that folic acid prevents cerebral palsy. However, folic acid supplementation is recommended for pregnant women to reduce the risk of neural tube defects in the developing fetus.
Neural tube defects are a group of birth defects that affect the brain, spine, and spinal cord and can increase the risk of cerebral palsy. Therefore, pregnant women must take folic acid supplements as their healthcare provider recommends to promote healthy fetal development and reduce the risk of birth defects.
Cerebral palsy is a condition that can affect anyone regardless of race, ethnicity, or socioeconomic status. However, certain factors can increase the risk of cerebral palsy, including premature birth, low birth weight, multiple births (e.g., twins, triplets), maternal infections during pregnancy, and brain damage due to lack of oxygen during birth.
Children who experience traumatic brain injuries, infections, or other medical conditions that affect the brain are also at increased risk of cerebral palsy. Additionally, genetics can play a role in the development of cerebral palsy, as some genetic mutations are associated with an increased risk of the condition.
It is important to note that many children with these risk factors do not develop cerebral palsy, and some children without them can still develop the condition.
Cerebral palsy in a fetus can be caused by damage to the developing brain during pregnancy. Several factors can contribute to brain damage and increase the risk of cerebral palsy, including:
- Genetic mutations: Some genetic mutations can affect the development and function of the brain, leading to cerebral palsy.
- Maternal infections: Infections such as rubella, cytomegalovirus, and toxoplasmosis can cause brain damage in the developing fetus, leading to cerebral palsy.
- Severe jaundice: High bilirubin levels in the baby’s blood can cause brain damage, leading to cerebral palsy.
- Oxygen deprivation during birth: When a fetus does not receive enough oxygen during delivery, it can lead to brain damage, which can cause cerebral palsy.
- Traumatic brain injury: A head injury to the fetus during pregnancy or delivery can lead to brain damage, which can cause cerebral palsy.
Identifying and managing these risk factors during pregnancy and delivery is important to reduce the risk of cerebral palsy.
It is impossible to definitively diagnose cerebral palsy (CP) while a baby is still in the womb. However, some prenatal risk factors and imaging techniques can help identify potential issues that may lead to CP.
Prenatal risk factors include maternal infections, exposure to toxins, or complications during pregnancy, such as placental abnormalities or intrauterine growth restriction. If these risks are present, doctors may monitor the pregnancy more closely.
Ultrasound and fetal MRI scans can provide insights into a baby’s brain development and may detect some anomalies associated with CP. However, these imaging techniques cannot confirm a CP diagnosis before birth.
A definitive diagnosis of cerebral palsy is usually made after the child is born through a combination of physical examinations, developmental assessments, and medical history analysis. Early intervention is crucial for managing CP, so if you have concerns, discuss them with your healthcare provider.
Ultrasound is not generally used to detect cerebral palsy. This is because cerebral palsy is caused by damage to the brain that occurs before, during, or shortly after birth, and ultrasound cannot detect this type of damage.
However, ultrasound can detect other conditions associated with cerebral palsy, such as abnormalities in the brain’s structure or bleeding in the brain. In addition, ultrasound can be used to monitor the growth and development of the fetus during pregnancy, which can help identify any potential risk factors for cerebral palsy.
Several infections during pregnancy can increase the risk of cerebral palsy in the child. These infections include:
- Cytomegalovirus (CMV): CMV is a common virus that can cause flu-like symptoms in pregnant women. Passing the virus to the fetus during pregnancy can cause brain damage and lead to cerebral palsy.
- Rubella: Rubella, also known as German measles, can cause miscarriage or stillbirth. If a woman contracts rubella during the early stages of pregnancy, it can lead to cerebral palsy in the child.
- Toxoplasmosis: Toxoplasmosis is a parasitic infection contracted through contact with contaminated food or cat feces. If a pregnant woman contracts toxoplasmosis, it can cause brain damage in the fetus, leading to cerebral palsy.
- Herpes simplex virus (HSV): HSV is a virus that can cause cold sores or genital herpes. If a woman contracts HSV during pregnancy, it can be passed to the fetus and cause brain damage, leading to cerebral palsy.
Pregnant women need to take steps to prevent these infections, such as practicing good hygiene, avoiding contact with people who are sick, and getting vaccinated if recommended by a healthcare provider. If a woman does contract one of these infections during pregnancy, prompt treatment can help reduce the risk of complications for both the mother and the fetus.
Cerebral palsy is a neurological disorder that affects movement, muscle tone, and coordination. It can occur during pregnancy, birth, or shortly after birth.
There are several ways to prevent cerebral palsy during pregnancy, including taking prenatal vitamins, avoiding infections, getting early and regular prenatal care, avoiding alcohol, tobacco, and drugs, managing chronic conditions, avoiding toxic substances, maintaining a healthy weight, and avoiding premature birth.
