What is Cerebral Palsy?
Cerebral palsy arises from abnormal development or damage to the brain areas responsible for controlling movement, balance, and posture. CP affects each person differently, with symptoms ranging from mild to severe. For parents, a diagnosis of CP can be overwhelming and challenging, but with the right information and support, families can work together to support each other through the good and the bad times.
We know that this may be a difficult journey to experience. We’re here to help you get to grips with the complexities of CP, starting with a clear definition and understanding of the different types. We’ll explore the causes and risk factors, how to recognise early symptoms, and the diagnostic process.
Furthermore, we will discuss practical strategies for managing CP, ensuring that children and their families receive the best possible care and support.
By understanding these aspects, parents can be better prepared to advocate for their child’s needs and help them lead fulfilling lives.
Defining Cerebral Palsy
CP is a neurological disorder caused by non-progressive brain damage or malformation that occurs while the child’s brain is under development, typically before birth. The primary indicator of CP is motor impairment, which can affect muscle tone, reflexes, posture, and coordination. While the brain damage that causes CP is permanent, the symptoms can change over time, and early intervention can significantly improve outcomes.
CP is classified based on the type and location of movement issues. The main types are Spastic, Dyskinetic, Ataxic, Mixed, and Hypotonic. Each type presents unique challenges and symptoms, which we will explain for you in the following sections.
According to HNEkidshealth “Cerebral Palsy (CP) is the most common physical disability in childhood. In Australia, a child who will have CP is born every 18 hours. There are about 34,000 people in Australia with CP”— you are not alone.
The Different Types of Cerebral Palsy
Spastic Cerebral Palsy
Spastic Cerebral Palsy is the most prevalent type, affecting around 70-80% of individuals diagnosed with CP. This type is characterised by increased muscle tone, leading to stiff and rigid muscles. The stiffness, or spasticity, can make movement difficult and can result in awkward or jerky motions. Spastic Cerebral Palsy is further classified based on which parts of the body are affected:
- Spastic Hemiplegia: This form affects one side of the body, typically the arm and leg on that side. Children with Spastic Hemiplegia may have difficulty using the affected hand and may walk with a limp.
- Spastic Diplegia: Primarily affects the legs, with the arms less severely impacted. Children with Spastic Diplegia often experience tight leg muscles, causing difficulty in walking and balancing. Many children with this type may walk on their toes due to tight heel muscles.
- Spastic Quadriplegia: The most severe form, affecting all four limbs, the trunk, and often the face. Children with Spastic Quadriplegia may have significant motor impairments and may also have associated intellectual disabilities, seizures, or vision and hearing problems.
Management of Spastic Cerebral Palsy often involves Physical Therapy to improve mobility and muscle strength, medications to reduce spasticity, and sometimes surgical interventions to correct orthopedic deformities.
Dyskinetic Cerebral Palsy
Dyskinetic Cerebral Palsy, also known as Athetoid Cerebral Palsy, is characterised by involuntary, uncontrolled movements. These movements can be slow and writhing (Athetosis) or rapid and jerky (Chorea). Muscle tone can vary between being too tight or too loose, often fluctuating unpredictably throughout the day. This can make tasks requiring fine motor control, such as writing or buttoning clothes, particularly challenging.
Children with Dyskinetic CP may experience:
- Athetosis: Slow, writhing movements that can affect the hands, feet, arms, or legs. These movements can make it difficult for children to hold objects or maintain a steady posture.
- Chorea: Rapid, jerky movements that can occur in any part of the body, making coordination and balance difficult.
- Dystonia: Involuntary muscle contractions that cause repetitive movements or abnormal postures.
Management strategies for Dyskinetic Cerebral Palsy focus on therapies that improve muscle control and coordination. Physical and Occupational Therapies are crucial in helping children develop skills for daily living.
Speech Pathology may also be necessary if the involuntary movements affect the muscles involved in speech. Medications to manage muscle tone fluctuations and assistive devices to aid in mobility and communication can also be beneficial.
Ataxic Cerebral Palsy
Ataxic Cerebral Palsy is the least common form, accounting for about 5-10% of CP cases.
It is characterised by problems with balance and coordination. Children with ataxic Cerebral Palsy often have issues with precise movements and may appear unsteady or shaky.
This type of CP affects the cerebellum, the part of the brain responsible for coordinating movements.
Key features of Ataxic Cerebral Palsy include:
- Impaired Coordination: Difficulty with tasks requiring fine motor skills, such as writing or buttoning a shirt. Movements may appear clumsy or poorly coordinated.
- Tremors: Involuntary shaking that can affect the hands and arms, especially when trying to perform tasks.
- Balance Issues: Walking with a wide gait to compensate for instability. Children may have trouble with activities that require balance, such as climbing stairs or riding a bicycle.
Management of Ataxic Cerebral Palsy focuses on improving coordination and balance through Physical Therapy. Occupational Therapy can help children develop fine motor skills, while adaptive equipment, such as braces or walkers, can aid in mobility.
Speech Pathology may be necessary if coordination issues affect speech. Regular monitoring and adjustments to the management plan can help children achieve their fullest potential.
Mixed Cerebral Palsy
Mixed Cerebral Palsy occurs when symptoms of more than one type of CP are present. The most common combination is Spastic-Dyskinetic Cerebral Palsy, where individuals experience both increased muscle tone and involuntary movements.
This type can present a complex set of challenges, as it encompasses the symptoms and difficulties associated with multiple forms of CP.
Children with Mixed Cerebral Palsy may exhibit:
- Spasticity: Stiff and rigid muscles, leading to difficulty with movement and posture.
- Athetosis: Slow, writhing movements that complicate fine motor tasks.
- Balance and Coordination Issues: Problems with stability and precise movements, often making daily activities more challenging.
Managing Mixed Cerebral Palsy requires a comprehensive and individualised approach. Physical Therapy can help improve muscle strength and coordination, while Occupational Therapy focuses on developing skills for daily living.
Speech Pathology may be needed to address communication challenges. Medications to manage muscle tone and involuntary movements, along with surgical interventions if necessary, can also be part of the treatment plan.
Collaboration among healthcare providers, therapists, and families is essential to address the multifaceted needs of children with Mixed Cerebral Palsy.
Hypotonic Cerebral Palsy
Hypotonic Cerebral Palsy, a rare form of CP, is characterised by diminished muscle tone, leading to excessively relaxed muscles and a floppy appearance.
Unlike the other types of CP, which involve spasticity or uncontrolled movements, Hypotonic Cerebral Palsy presents with low muscle tone (hypotonia), which can significantly impact a child’s strength and stability.
Key features of Hypotonic Cerebral Palsy include:
- Floppiness: Muscles are overly relaxed, making it difficult for children to maintain posture and perform movements. Infants may appear limp and have trouble holding up their head or sitting without support.
- Weakness: Reduced muscle strength, leading to delays in reaching motor milestones such as crawling, sitting, and walking.
- Joint Instability: Loose joints and poor control over movements, increasing the risk of dislocations and other joint problems.
Management of Hypotonic Cerebral Palsy focuses on strengthening muscles and improving stability. Physical Therapy is essential to help children develop muscle tone and coordination. Occupational Therapy can assist in enhancing daily living skills and adapting tasks to the child’s abilities.
In some cases, assistive devices such as braces or orthotics may be needed to support joint stability and improve mobility. Speech Pathology may be necessary if low muscle tone affects the muscles involved in speech.
Early and consistent intervention can help children with Hypotonic Cerebral Palsy improve their functional abilities and quality of life.
What Causes Cerebral Palsy
The exact cause of CP is often unknown, but several factors can contribute to its development, including:
- Prenatal Causes: Infections during pregnancy (such as Rubella or Cytomegalovirus), poor maternal health, or complications such as multiple births.
- Perinatal Causes: Complications during childbirth, including premature birth, low birth weight, lack of oxygen (Asphyxia), or prolonged labour.
- Postnatal Causes: Infections (such as Meningitis), traumatic brain injuries, or severe Jaundice in newborns.
It is important to note that many cases of CP occur without any clear cause.
Recognising Symptoms and Early Indicators
Early recognition of CP can lead to better management and outcomes. Common early indicators include:
- Developmental Delays: Not reaching milestones such as sitting, crawling, or walking at expected ages.
- Abnormal Muscle Tone: Either too stiff or too floppy.
- Unusual Postures: Preference for one side of the body or awkward positioning of limbs.
- Reflex Abnormalities: Persistence of primitive reflexes that typically disappear in early infancy.
- Coordination and Movement Issues: Difficulty with fine motor skills, such as picking up objects or using utensils.
Parents who notice these signs should consult a healthcare professional for further evaluation.
Diagnostic Criteria of Cerebral Palsy and How to Get a Diagnosis
Diagnosing CP involves several steps:
- Medical History and Physical Examination: A thorough review of the child’s medical history and a detailed physical examination to assess muscle tone, reflexes, and motor skills.
- Developmental Monitoring: Tracking the child’s growth and developmental milestones over time.
- Neuroimaging: MRI or CT scans to detect brain abnormalities that may indicate CP.
- Medical Lab Tests: To rule out other conditions that may cause similar symptoms.
Early diagnosis is an absolute must for initiating appropriate interventions and therapies. Parents should seek evaluation from a paediatrician or a specialist in paediatric neurology if they suspect CP.
How To Manage Cerebral Palsy and Support Your Child and Family
Managing CP involves a multidisciplinary approach tailored to the individual needs of the child. Key strategies include:
- Therapies: Physical Therapy to improve motor skills, Occupational Therapy to enhance daily living activities, and Speech Pathology for communication difficulties.
- Medical Interventions: Medications to manage muscle spasticity and pain, and surgical procedures to correct physical abnormalities.
- Assistive Devices: Use of braces, walkers, wheelchairs, or communication aids to improve mobility and independence.
- Educational Support: Special education services and individualised education plans (IEPs) to address learning challenges.
- Emotional and Social Support: Counseling for the child and family, and connecting with support groups for emotional and practical assistance.
Parents play an invaluable role in advocating for their child’s needs and accessing the resources necessary for their development. It’s important as a parent to remember there are support groups out there with people going through similar journeys – you are never alone.
Understanding and Living with Cerebral Palsy
Caring for a child with CP requires patience, dedication, and a comprehensive understanding of the condition. By staying informed about the types, causes, symptoms, and management strategies, parents can better support their child’s growth and well-being.
Occupational Therapy and Speech Pathology are particularly beneficial in enhancing the quality of life for children with CP, helping them achieve greater independence and communication skills.
Remember, with the right support and interventions, children with CP can lead fulfilling and meaningful lives.
