Cerebral palsy is one of the most common lifelong physical disabilities in the world. Approximately 17 million people suffer from it globally. But why? Why is it so common? While there is no one-size-fits-all answer to this question, the condition’s prevalence can be connected to a variety of factors. For instance, premature birth, maternal infections, and neonatal brain damage are major contributors to this disability.
Premature birth, which occurs before the 37th week of pregnancy, is one of the leading causes of cerebral palsy. Such an early birth can interrupt the baby’s brain development, resulting in a lack of oxygen or blood flow to the brain, which can cause severe damage. In fact, research shows that the more premature the birth, the higher the likelihood of developing cerebral palsy. The underlying reason for this is that brain development is incomplete in the third trimester of pregnancy. Hence, early delivery may subject the baby to significant neurological trauma, leading to cerebral palsy.
Maternal infections during pregnancy can also increase the chances of a baby being born with cerebral palsy. Certain common infections like meningitis, German measles, toxoplasmosis, and syphilis can all affect the developing brain of a fetus. Furthermore, neonatal brain damage, that is damage to the brain shortly after birth, can cause cerebral palsy. This could be from a lack of blood flow or oxygen to the brain or from a traumatic injury during birth. With so many potential contributing factors, it is no wonder that cerebral palsy has become so prevalent.
Causes of Cerebral Palsy
Cerebral Palsy is a neurological disorder that affects an estimated 17 million people worldwide. Though there isn’t a single cause that can be attributed to all cases of Cerebral Palsy, a variety of factors can contribute to the development of this condition. Here we will explore some of the most common causes of Cerebral Palsy:
- Brain Damage Before Birth: Brain damage that occurs before or during birth can lead to Cerebral Palsy. Possible causes of this type of damage include maternal infections, lack of oxygen to the brain, and problems with blood flow.
- Brain Damage After Birth: Brain damage that occurs after birth can be caused by a variety of factors, including head injuries, infections like meningitis or encephalitis, and stroke.
- Genetics: Cerebral Palsy is not usually inherited, but genetic factors can contribute to some cases of the condition. For example, mutations in certain genes can increase the risk of brain damage during development or after birth.
While these are some of the most common causes of Cerebral Palsy, it’s worth noting that many cases of the condition have no single identifiable cause. Researchers are still working to understand the complex mix of genetic and environmental factors that can contribute to Cerebral Palsy.
Risk Factors for Cerebral Palsy
Cerebral Palsy affects approximately 500,000 people in the US, and according to recent studies, about 1 in every 323 children is diagnosed with it. While the exact cause of cerebral palsy is not yet known, it is believed that a combination of genetic and environmental factors can cause the disorder. Below are some of the major risk factors associated with cerebral palsy:
- Low birth weight
- Premature birth
- Multiple births (twins, triplets, etc.)
Low Birth Weight, Premature Birth, and Multiple Births
Babies who are born weighing less than 5.5 pounds are at a higher risk of developing cerebral palsy than babies born at a healthy weight. Additionally, babies who are born prematurely (before 37 weeks) are more likely to develop cerebral palsy than those born at full term. Cerebral palsy occurs more frequently in multiple births (twins, triplets, etc.) compared to single birth pregnancies. The reason for this is that often, multiple births lead to premature births and low birth weight. These factors can contribute to brain damage and an increased risk of developing cerebral palsy.
Studies have shown that the earlier a baby is born, the higher the risk of cerebral palsy. For example, babies born before 28 weeks have an 11% risk of developing cerebral palsy while babies born between 34 and 36 weeks have a 1.5% risk. The longer a baby stays in the womb, the more time the brain has to develop, reducing the risk of cerebral palsy.
| Birth Weight | Risk of Cerebral Palsy |
|---|---|
| Less than 5.5 lbs | 10 times more likely |
| Between 5.5 lbs and 8.5 lbs | Normal Risk |
| More than 8.5 lbs | Slightly increased risk |
It is important to note that not all premature babies or babies with low birth weight will develop cerebral palsy. Many babies who experience these risk factors go on to live healthy and normal lives. However, these risk factors increase the chances of developing the disorder and should be closely monitored by doctors and parents.
Types of Cerebral Palsy
Cerebral palsy is a group of neurological disorders that affect body movement and muscle coordination. It is the most common motor disability in childhood, with 1 in 323 children in the United States affected by it. There are four main types of cerebral palsy, and each type is defined by the areas of the brain affected:
- Spastic cerebral palsy – This is the most common type of cerebral palsy, affecting around 80% of people with the condition. It causes stiff and jerky movements, making it difficult to control muscles and perform everyday activities. Spastic cerebral palsy is caused by damage to the motor cortex, which is responsible for movement planning and execution.
- Dyskinetic cerebral palsy – This type of cerebral palsy affects about 6% of people with the condition. It causes involuntary and uncontrolled movements, such as twisting, writhing, or repetitive motions. Dyskinetic cerebral palsy is caused by damage to the basal ganglia, which is responsible for controlling movement.
- Ataxic cerebral palsy – This type of cerebral palsy affects about 5% of people with the condition. It causes problems with balance and coordination, making it difficult to walk or perform fine motor tasks, such as writing or buttoning clothes. Ataxic cerebral palsy is caused by damage to the cerebellum, which is responsible for motor coordination.
- Mixed cerebral palsy – This type of cerebral palsy is a combination of two or more of the other types.
Causes of Cerebral Palsy
The exact causes of cerebral palsy are not yet fully understood, but it is known to be caused by damage to the developing brain, typically before or during birth. Possible causes of the damage include:
- Brain malformations
- Lack of oxygen to the brain during delivery
- Infection during pregnancy
- Head injury
- Jaundice and kernicterus
Symptoms of Cerebral Palsy
The symptoms of cerebral palsy can vary widely, depending on the type and severity of the condition. Some common symptoms include:
- Delayed motor milestones, such as rolling over, sitting up, or crawling
- Tight or spastic muscles
- Difficulty walking or crawling
- Trouble with fine motor skills, such as writing or buttoning clothes
- Intellectual disabilities or developmental delays
- Vision or hearing problems
Treatment for Cerebral Palsy
Although there is no cure for cerebral palsy, there are treatments that can help manage the symptoms and improve quality of life. Treatment options may include:

- Imaging tests: Tests such as magnetic resonance imaging (MRI) and computed tomography (CT) scans can help identify brain abnormalities and lesions that may be associated with cerebral palsy.
- Electroencephalogram (EEG): This test measures electrical activity in the brain and can be used to identify abnormal brain wave patterns that may be associated with cerebral palsy.
In addition to these methods, screening for cerebral palsy can also be done in a number of ways, including:
- Newborn screening: This involves a series of tests that are performed shortly after birth to detect any neurological abnormalities.
- Developmental monitoring: This involves monitoring a child’s development over time to detect any abnormalities or delays.
- Genetic testing: In some cases, genetic testing can help identify the underlying causes of cerebral palsy.
It’s important to note that not all children with cerebral palsy will exhibit the same symptoms or have the same underlying causes. Therefore, a thorough evaluation by a skilled medical professional is critical to ensuring an accurate diagnosis and providing the best possible care.
| Method | Advantages | Disadvantages |
|---|---|---|
| Developmental assessments | Provides a comprehensive evaluation of a child’s development | Can be time-consuming and may require multiple visits |
| Imaging tests | Can identify brain abnormalities and lesions | May not detect milder cases of cerebral palsy |
| EEG | Can identify abnormal brain wave patterns associated with cerebral palsy | May not be able to pinpoint the exact cause of a child’s symptoms |
In summary, diagnosis and screening for cerebral palsy is a complex process that requires a skilled medical professional and a thorough evaluation. Early detection and intervention are critical to ensuring the best possible outcomes for children with cerebral palsy.
