Cerebral palsy- genetic, congenital, or acquired? Explained

lifestyle-child-wheelchair (1)

Approximately 2.3 to 3.6 out of every 1,000 births are diagnosed with cerebral palsy. However, the good news is that early intervention and the right care can transform their journey.

As parents, learning about cerebral palsy (CP) can be overwhelming. The journey often begins with questions about what caused your child’s condition and whether it was due to genetics, circumstances during pregnancy, or factors during birth. 

It’s important to know that you are not alone in seeking answers, and many families share similar concerns.

What is Cerebral Palsy?

Cerebral palsy refers to a group of disorders that impact movement, muscle tone, and posture, resulting from abnormal brain development or damage to the brain while it is still developing. CP is generally noticed in early childhood. It varies widely in severity and impact. 

CP is termed as a lifelong condition; however, its impacts can be eased through appropriate interventions, therapies, and supports. Even effects on CP can vary widely among children because they not only impair motor skills but can also affect speech, cognition, and daily living activities.

 

General Symptoms of Cerebral Palsy (CP)

  • Difficulty in controlling movements.
  • Uncontrolled reflex actions.
  • Either stiff muscles or reduced muscle tone.
  •  Potential for epilepsy.
  • Challenges with learning and development.

Cerebral Palsy Types

Type of Cerebral Palsy

Characteristics

Associated Motor Impairments

Spastic CP

Stiff muscles and exaggerated reflexes

Difficulty in movement, tightness in limbs

Dyskinetic CP

Uncontrolled movements and challenges with posture

Fluctuating muscle tone, awkward movements

Ataxic CP

Balance and coordination issues

Unsteady gait, difficulty with precise movements

 

Understanding these classifications is crucial for tailoring effective interventions and support strategies for each individual.

The Genetic Component of Cerebral Palsy

Can cerebral palsy be genetic? Yes, while cerebral palsy (CP) is not classified as a hereditary condition, certain genetic factors can increase the likelihood of developing it. Hereditary traits may predispose individuals to CP, particularly through a complex interplay of genetic influences and environmental factors.

Studies show that about 70% of brain damage leading to CP occurs before birth, primarily during the second and third trimesters. 

However, genetic factors can contribute to obstetric risk factors such as preterm birth and placental issues, which are significant in the development of CP. 

Notably, familial recurrence can occur, where CP appears in multiple family members, often due to autosomal – recessive or X-linked-recessive inheritance patterns.

Research indicates that certain genetic mutations and structural DNA changes are linked to CP in some cases. 

For instance, a study conducted at Toronto’s Hospital for Sick Children found that in about 10% of the children studied, DNA alterations were present, with 5% showing a direct correlation to CP. 

These findings suggest that while CP isn’t purely genetic, there are identifiable genetic components that can influence its development.

Ultimately, understanding the genetic aspects of cerebral palsy helps in recognizing risk factors and guiding preventive measures, though further research is needed to fully elucidate these complex interactions.

Congenital vs. Acquired Cerebral Palsy

Cerebral palsy can be categorized as either congenital or acquired, and distinguishing between the two is crucial for diagnosis and treatment.

 

Congenital Cerebral Palsy

Congenital CP accounts for about 80-90% of cases. It typically arises during fetal development and can result from various factors, including:

  • Genetic abnormalities: Mutations or inherited conditions can lead to brain development issues.
  • Infections during pregnancy: Conditions like rubella or cytomegalovirus can affect fetal brain development.
  • Maternal health issues: Conditions like diabetes or hypertension can increase the risk of CP in the child.

 

Acquired Cerebral Palsy

Although less frequent, acquired CP is the type of CP that develops in a child after he or she has been born. Many times, it is caused by either brain injury or illness. Such causes may include:

  • Head trauma: The child would have suffered from an accident or maybe a fall, resulting in brain damage.
  • Infection: This is caused by either meningitis or other kinds of infections affecting the child’s brain.
  • Lack of oxygen: A condition such as near-drowning or suffocation causes damage in the child’s brain.

 

Knowing whether the CP is congenital or acquired will have a lot of implications on the treatment plan and support strategies for the affected child.

Early Detection: Can Cerebral Palsy Be Detected Before Birth?

Sometimes parents wonder if cerebral palsy could have been detected before their child was born. While there is currently no test that guarantees certainty in predicting whether a child would have cerebral palsy, there are several prenatal tests that can indicate if your child is at risk. 

 

For instance, advanced imaging studies such as MRI may sometimes identify fetal anomalies of the brain, or genetic testing can diagnose specific genetic conditions known to raise a child’s risk for CP.

 

These tests alone do not confirm cerebral palsy but can notify parents and healthcare providers that there is a possible developmental challenge on the horizon. Early intervention remains the key to maximizing the outcome for children with CP, regardless of when the condition is identified.

The Importance of Early Intervention

For parents of children with cerebral palsy (CP), early intervention is crucial. Engaging in therapies like occupational, speech, and physical therapy can significantly improve your child’s motor skills, communication abilities, and overall independence.  Addressing these needs early leads to better long-term outcomes.

A multidisciplinary approach, involving medical professionals, therapists, and educators, creates a robust support network for both the child and the family. This collaborative effort ensures comprehensive care tailored to your child’s unique needs.

Moreover, education and advocacy equip families with the knowledge to navigate the complexities of CP. Understanding these challenges enables parents to seek the best possible medical care and support for their child, ultimately fostering a more empowered and informed parenting journey.

Early Intervention: The Key to Your Child’s Growth and Development at Kids Neuro

Understanding the importance of early intervention can be really important for families and healthcare providers relating to the genetic, congenital or acquired causation of cerebral palsy. Every child’s history with CP is unique and has been constructed from a diversity of factors in development and wellness.

Of course, just knowing the complexities that underlie cerebral palsy becomes the essential pathway for early detection and intervention. It is somewhat comforting to know that, although their child’s life is much tougher than it would have been without this lifelong condition, so many resources, therapies, and communities can offer support to them.

The patients along with their families, upon visiting Kids Neuro Clinic, find themselves in the most caring system with regard to neurological disorders such as cerebral palsy, which is always approached with concern and sympathetic ways.
