What Is Cerebral Palsy (CP)

Cerebral palsy (CP) is a group of neurological disorders that affect movement, balance, and posture. It is caused by damage to the developing brain, usually before or during birth, although it can also occur in early childhood.

The word โ€œcerebralโ€ refers to the brainโ€™s cerebrum, which is part of the brain that regulates motor function. โ€œPalsyโ€ describes the paralysis of voluntary movement in certain body parts.

Types Of Cerebral Palsy And Its Causes
Spastic CP

Spastic cerebral palsy (CP) is the most common type of CP, accounting for about 70-80% of all cases. It is characterized by increased muscle tone or stiffness, which can make movement and posture complex.

In spastic CP, brain damage affects the ability of the nerves to control the muscles, resulting in abnormal muscle tone and reflexes. This can cause muscles to contract or spasm, which makes movement more difficult and can also result in contractures (permanent shortening of muscles or tendons) over time.

Spastic CP can affect different parts of the body, depending on which areas of the brain are damaged. Some people with spastic CP may have predominantly lower limb involvement, while others may have more severe upper limb involvement. In some cases, spastic CP can affect all four limbs (quadriplegia) or just one side of the body (hemiplegia).

The severity of spastic CP can also vary widely, from mild spasticity that only affects certain movements or postures, to severe spasticity that affects all movements and makes independent mobility difficult. Treatment for spastic CP may include physical therapy, medication, and/or surgery to manage spasticity and improve function.

Dyskinetic CP:

Dyskinetic cerebral palsy (CP) is a type of CP that is characterized by involuntary and uncontrollable movements. It is also sometimes referred to as athetoid or choreoathetosis CP.

In dyskinetic CP, the damage to the brain affects the ability to control and coordinate movements, resulting in involuntary muscle contractions and twisting or writhing movements. These movements can affect the limbs, face, and torso, and can vary in severity and frequency. The involuntary movements can interfere with activities of daily living, such as eating, drinking, and writing.

People with dyskinetic CP may also have difficulty maintaining a stable posture or holding their body in a certain position. This can make it difficult to sit, stand, or walk without support.

Dyskinetic CP is often caused by damage to the basal ganglia, a part of the brain that controls voluntary movements. It can be further classified into different subtypes, including choreoathetosis (involuntary movements that are jerky and writhing), dystonia (sustained involuntary muscle contractions that can cause abnormal postures), and athetosis (slow, writhing movements that can affect the limbs and face).

Treatment for dyskinetic CP may include physical therapy, medication, and/or surgery to manage symptoms and improve function. However, dyskinetic CP can be difficult to manage, and people with this type of CP often require ongoing support and accommodations.

Ataxic CP:

Ataxic cerebral palsy (CP) is a type of CP that is characterized by problems with balance and coordination. It is the least common type of CP, accounting for approximately 5-10% of all cases.

In ataxic CP, the damage to the brain affects the cerebellum, a part of the brain that controls balance and coordination. This can result in problems with voluntary movements, such as walking, reaching, and grasping. People with ataxic CP may have difficulty with fine motor skills, such as writing or buttoning clothes.

Symptoms of ataxic CP may include an unsteady gait, tremors, difficulty with balance and coordination, and problems with depth perception. People with ataxic CP may also have difficulty with speech, including problems with articulation and volume control.

Treatment for ataxic CP may include physical therapy to improve balance and coordination, speech therapy to address communication difficulties, and assistive devices to aid with mobility and activities of daily living. While ataxic CP can be challenging to manage, many people with this type of CP are able to lead independent and fulfilling lives with the help of supportive services and accommodations.

Hypotonic CP

Hypotonic cerebral palsy (CP) is a type of CP that is characterized by low muscle tone, also known as hypotonia. Hypotonia can affect the entire body or specific parts of the body, such as the arms or legs.

In hypotonic CP, the damage to the brain affects the motor neurons responsible for muscle tone. As a result, the muscles may feel soft and floppy, and movements may appear slow or sluggish. People with hypotonic CP may have difficulty with gross motor skills, such as sitting up or crawling, and fine motor skills, such as grasping and holding objects.

Other symptoms of hypotonic CP may include poor reflexes, poor posture, and difficulty with feeding and swallowing.

Treatment for hypotonic CP may include physical therapy to strengthen the muscles and improve mobility, occupational therapy to improve fine motor skills, and speech therapy to address communication difficulties. Assistive devices, such as braces or orthotics, may also be recommended to support mobility and improve posture.

While hypotonic CP can be challenging to manage, many people with this type of CP are able to lead independent and fulfilling lives with the help of supportive services and accommodations.

Mixed CP:

Mixed cerebral palsy (CP) is a type of CP that involves a combination of two or more different types of CP, including spastic, dyskinetic, and ataxic. The exact symptoms and severity of mixed CP can vary widely, depending on which types of CP are present and how severely they affect the individual.

For example, a person with mixed CP may have spasticity and muscle stiffness in some limbs, dyskinetic movements in others, and problems with balance and coordination. The combination of symptoms can make it difficult for the person to move, communicate, and perform activities of daily living.

Treatment for mixed CP is typically individualized, depending on the specific symptoms and needs of the person with CP. Treatment may include physical therapy to improve mobility and muscle strength, occupational therapy to improve fine motor skills and activities of daily living, speech therapy to address communication difficulties, and medication to manage spasticity or other symptoms.

While mixed CP can be challenging to manage, many people with this type of CP are able to lead independent and fulfilling lives with the help of supportive services and accommodations. A team of healthcare professionals, including physicians, therapists, and other specialists, may be involved in the care of a person with mixed CP. The goal of treatment is to maximize the person’s function, independence, and quality of life.

Cerebral Palsy Signs & Symptoms

The signs and symptoms of cerebral palsy (CP) can vary widely depending on the type and severity of the condition. However, some common signs and symptoms of CP include:

  1. Abnormal muscle tone: People with CP may have muscles that are too stiff (spasticity) or too floppy (hypotonia).
  2. Delayed motor milestones: Infants with CP may not meet developmental milestones on time, such as sitting up, crawling, or walking.

Cerebral Palsy (CP) Diagnosis

Diagnosing cerebral palsy (CP) usually involves a combination of medical history, physical exam, and diagnostic tests. Here are some common steps in the diagnostic process:

  1. Medical history: The healthcare professional typically asks questions about the child’s development, including motor milestones, any problems during pregnancy or delivery, and any other medical or developmental concerns.
  2. Physical exam: The healthcare professional performs a physical exam, checking for signs of abnormal muscle tone, reflexes, and movements.
  3. Developmental screening: The healthcare professional may perform developmental screening tests to evaluate the child’s development in areas such as movement, communication, and problem-solving.
  4. Diagnostic tests: Additional tests may be ordered to help confirm the diagnosis of CP or rule out other conditions. These may include:
  • Magnetic resonance imaging (MRI) or computed tomography (CT) scans evaluate the brain for signs of damage or abnormalities.
  • Electroencephalogram (EEG) to evaluate brain activity and detect seizure disorders.
  • Genetic testing to look for underlying genetic causes of CP.
Risk Factors

There are several factors that can increase the risk of developing cerebral palsy (CP). Some common risk factors include:

  1. Premature birth: Infants born before 37 weeks gestation are at increased risk of CP.
  2. Low birth weight: Infants weighing less than 2.5 kg (5.5 lbs) at birth are at increased risk of CP.
  3. Multiple births: Twins, triplets, and other multiple births are at increased risk of CP.
  4. Infections during pregnancy: Infections such as rubella, cytomegalovirus, or toxoplasmosis during pregnancy can increase the risk of CP.
  5. Complications during birth: Problems during delivery, such as fetal distress, can increase the risk of CP.
  6. Brain injury or infection: Brain injury or infection in the early months or years of life can increase the risk of CP.
  7. Rh incompatibility: When the mother’s blood type is Rh-negative and the baby’s blood type is Rh-positive, the mother’s immune system may attack the baby’s red blood cells, leading to brain damage and an increased risk of CP.
  8. Jaundice and kernicterus: Severe jaundice or kernicterus, a type of brain damage caused by high levels of bilirubin in the blood, can increase the risk of CP.

Some people with CP may have mild symptoms and be able to live relatively independent lives, while others may have more severe symptoms and require ongoing care and support.

Here are some general factors that can affect the prognosis for CP:

  1. Type and severity of CP: The type and severity of CP can greatly impact the prognosis. For example, people with spastic CP may have more mobility and functional limitations than those with ataxic or dyskinetic CP.
  2. Age of diagnosis: Early diagnosis and treatment are important for improving outcomes for people with CP.
  3. Access to treatment and support: Access to therapies, medications, assistive devices, and other supports can greatly improve outcomes for people with CP.
  4. Coexisting conditions: Coexisting conditions, such as intellectual disability or seizures, can also impact the prognosis for CP.
  5. Family support and resources: Family support and access to resources and support groups can be important factors in improving outcomes for people with CP.
Treatment, Medication, And Therapy

The treatment for cerebral palsy (CP) typically involves a multidisciplinary approach that addresses the individual’s specific needs and symptoms. Here are some common treatment options:

  1. Physical therapy: Physical therapy can help improve strength, flexibility, and coordination, and may involve exercises, stretching, and the use of assistive devices.
  2. Occupational therapy: Occupational therapy can help improve fine motor skills and daily living activities, and may involve exercises, adaptive equipment, and modifications to the home or workplace.
  3. Speech therapy: Speech therapy can help improve communication skills, including speech, language, and feeding.
  4. Medications: Medications may be used to manage symptoms of CP, such as muscle spasms, seizures, and pain.
  5. Surgery: In some cases, surgery may be recommended to improve mobility or reduce spasticity.
  6. Assistive devices: Assistive devices, such as braces, orthotics, wheelchairs, and communication devices, can help improve mobility and communication.
  7. Alternative therapies: Some people with CP may benefit from alternative therapies, such as acupuncture, massage, or hydrotherapy. However, it’s important to discuss any alternative therapies with a healthcare professional to ensure they are safe and effective.
