Understanding Athetoid Cerebral Palsy
Athetoid cerebral palsy, also known as dyskinetic cerebral palsy, is a movement disorder characterized by involuntary and uncontrollable muscle movements. According to the National Center for Biotechnology Information, this subtype represents 12% to 14% of all cerebral palsy cases, making it the second most common form of the condition.
Unlike spastic cerebral palsy which affects muscle tone and stiffness, athetoid cerebral palsy primarily impacts movement control. Children with this condition experience slow, writhing movements (athetosis), rapid irregular movements (chorea), or twisting motions (dystonia) that they cannot control.
Key Facts About Athetoid Cerebral Palsy
- Affects 12-14% of cerebral palsy patients
- Caused by damage to the basal ganglia and thalamus
- Results in involuntary movements that worsen with stress
- Often preventable through proper medical care during birth
- New York families have up to 10 years to file legal claims
What Causes Athetoid Cerebral Palsy?
Athetoid cerebral palsy occurs when specific areas of the brain—the basal ganglia and thalamus—sustain damage during late pregnancy, birth, or shortly after delivery. According to Cleveland Clinic, these brain structures are responsible for coordinating and controlling body movements.
Primary Causes of Brain Damage
Several preventable medical complications can lead to the type of brain damage that causes athetoid cerebral palsy:
🩸 Oxygen Deprivation (Hypoxia)
Lack of oxygen during labor and delivery can damage the basal ganglia. This may occur due to umbilical cord complications, placental abruption, or prolonged labor without proper monitoring.
🟡 Kernicterus (Severe Jaundice)
When newborn jaundice goes untreated, toxic levels of bilirubin can accumulate in the brain tissue, particularly affecting the basal ganglia. This is one of the most preventable causes of athetoid cerebral palsy.
🧠 Intracranial Hemorrhage
Bleeding in the brain during or shortly after birth can damage critical motor control areas. This may result from birth trauma, improper use of delivery instruments, or failure to perform a timely cesarean section.
🦠 Infections
Maternal infections during pregnancy or neonatal infections can trigger inflammation that damages developing brain tissue. Proper screening and treatment can often prevent these complications.
Risk Factors for Athetoid Cerebral Palsy
While athetoid cerebral palsy can occur in any birth, certain factors increase the risk:
- Premature birth (before 38 weeks) limiting the infant’s ability to process bilirubin
- Low birth weight making infants more vulnerable to complications
- Difficult or prolonged labor without adequate fetal monitoring
- Birth trauma from improper use of forceps or vacuum extraction
- Delayed cesarean section when emergency delivery is medically necessary
- Maternal health conditions not properly managed during pregnancy
Importantly, research from the NCBI indicates that dyskinetic cerebral palsy occurs more frequently in term infants compared to premature babies, distinguishing it from other forms of cerebral palsy.
Recognizing Symptoms of Athetoid Cerebral Palsy
The hallmark symptoms of athetoid cerebral palsy involve involuntary movements that a child cannot control. According to medical experts, these movements typically become apparent between ages 2 and 3, though developmental delays may be noticed earlier.
Primary Movement Symptoms
Additional Symptoms and Complications
Children with athetoid cerebral palsy often experience symptoms beyond involuntary movements:
- Speech difficulties (dysarthria): Involuntary movements of the face, tongue, and throat muscles make speaking challenging
- Feeding and swallowing problems: Difficulty coordinating the muscles needed for eating
- Drooling: Reduced control of facial muscles and difficulty swallowing saliva
- Hearing loss: A common co-occurring condition, particularly when kernicterus is the underlying cause
- Visual impairments: Eye movement control problems
- Intellectual disabilities: More than half of patients experience cognitive challenges
- Seizures: Epilepsy affects a significant portion of children with this condition
One distinctive characteristic noted by medical professionals is that involuntary movements often increase during periods of emotional stress or excitement and disappear when the child is sleeping or deeply focused on a task.
Diagnosis and Medical Evaluation
Diagnosing athetoid cerebral palsy involves comprehensive medical evaluation that typically occurs during early childhood. Healthcare providers use multiple assessment methods:
Diagnostic Process
- Developmental Milestone Assessment: Tracking whether the child meets expected motor, cognitive, and social milestones
- Physical Examination: Evaluating muscle tone, movement patterns, coordination, and reflexes
- MRI Imaging: Magnetic resonance imaging reveals damage to the basal ganglia and thalamus
- Blood Tests: Ruling out other conditions with similar symptoms, such as metabolic disorders
- Hearing and Vision Tests: Identifying associated sensory impairments
- Genetic Testing: Excluding hereditary conditions that may cause similar movement disorders
Early diagnosis is crucial for beginning therapeutic interventions that can improve outcomes and quality of life.
Treatment Options for Athetoid Cerebral Palsy
While there is no cure for athetoid cerebral palsy, a range of treatments can help manage symptoms and improve function. The condition is nonprogressive, meaning it does not worsen over time, but lifelong management is typically necessary.
Therapeutic Interventions
Physical Therapy
Generally the first line of treatment, physical therapy helps improve muscle strength, coordination, and mobility. Therapists work on posture, balance, and functional movements.
Occupational Therapy
Focuses on developing skills for daily living activities such as dressing, feeding, and using adaptive equipment to increase independence.
Speech Therapy
Addresses communication challenges, breathing difficulties, and swallowing problems common in children with dyskinetic cerebral palsy.
Medical Treatments
Several medications and medical interventions may help control symptoms:
- Anticholinergic medications (such as trihexyphenidyl) to reduce involuntary movements by blocking certain brain chemicals
- Muscle relaxants (including oral baclofen) to decrease muscle spasms and pain
- Levodopa and dopamine agonists for managing dystonia
- Benzodiazepines for reducing muscle tension and anxiety
- Intrathecal baclofen pump delivering medication directly to the central nervous system with fewer side effects
- Botulinum toxin injections to temporarily reduce involuntary movements in specific muscles
Advanced Interventions
For severe cases, more invasive treatments may be considered:
- Deep brain stimulation (DBS): Electrodes implanted in the brain help control abnormal movements by delivering electrical impulses
- Orthopedic surgery: Corrects limb deformities, contractures, or skeletal abnormalities that develop over time
- Selective dorsal rhizotomy: A surgical procedure that may help reduce dystonia in selected cases
The NCBI notes that while these treatments can reduce symptoms, oral medications for dyskinetic cerebral palsy generally show “low efficacy,” emphasizing the importance of a comprehensive interprofessional approach combining multiple therapies.
Legal Rights for Families in New York
When athetoid cerebral palsy results from preventable medical errors during pregnancy, labor, or delivery, families in New York have the legal right to pursue compensation through a birth injury medical malpractice claim. Understanding your rights is the first step toward securing the resources your child needs for lifelong care.
When Medical Negligence Causes Athetoid Cerebral Palsy
According to medical malpractice data, cerebral palsy or brain injury was involved in 41% of birth injury malpractice claims. Healthcare providers may be held liable when their negligence leads to conditions that cause athetoid cerebral palsy:
Common Forms of Medical Negligence
- Failure to monitor fetal distress during labor, missing signs of oxygen deprivation
- Delayed cesarean section when emergency delivery is medically indicated
- Improper use of delivery instruments (forceps, vacuum extractors) causing head trauma
- Failure to diagnose and treat jaundice allowing bilirubin levels to reach toxic levels (kernicterus)
- Inadequate response to umbilical cord complications such as prolapse or nuchal cord
- Failure to diagnose or treat maternal infections that can harm the developing baby
- Medication errors during pregnancy or delivery
- Improper management of high-risk pregnancies
Research indicates that up to 50% of birth injuries are preventable and result from errors made by healthcare professionals during labor and delivery. When kernicterus is the cause, the preventability rate is even higher, as jaundice monitoring and treatment protocols are well-established.
Proving Medical Malpractice in New York
To succeed in a birth injury claim, families must establish four key elements:
- Duty of Care: The healthcare provider had a professional relationship with you and your baby
- Breach of Standard of Care: The provider’s actions (or inactions) fell below the accepted medical standard
- Causation: The breach directly caused your child’s brain injury
- Damages: Your child suffered measurable harm requiring compensation
Establishing breach of the standard of care requires expert testimony from qualified medical professionals who can explain what a competent provider should have done differently in the same circumstances. Birth injury attorneys work with obstetricians, neonatologists, neurologists, and other specialists to build compelling evidence.
New York’s Statute of Limitations for Birth Injury Claims
Understanding the legal time limits is critical for protecting your family’s rights. New York has specific rules governing how long you have to file a birth injury lawsuit.
New York Statute of Limitations (2025)
General Rule: Under New York CPLR §208, families have until the child’s 10th birthday to file a medical malpractice claim for birth injuries.
How it works: The standard 2.5-year statute of limitations for medical malpractice is “tolled” (paused) during the child’s infancy, giving you a full 10 years from the date of birth.
Important Exceptions and Special Rules
Discovery Rule: If the injury was not immediately apparent and was only discovered later, you may still file a claim as long as it falls within the 10-year window. This is particularly relevant for cerebral palsy, which may not be diagnosed until months or years after birth.
Municipal Hospitals: If your child was born at a NYC Health + Hospitals facility or other government-run hospital, you must file a Notice of Claim within 90 days of the injury. This strict requirement can permanently bar your case if missed. Courts may allow late filing up to 1 year and 90 days in very limited circumstances.
Certificate of Merit: New York law (CPLR §3012-a) requires a Certificate of Merit from a qualified medical expert. If the statute of limitations is approaching, you can file your lawsuit without it but must submit the certificate within 90 days after filing.
Wrongful Death: If birth injuries result in the child’s death, families have 2.5 years from the date of death to file a wrongful death claim.
⚖️ Important: While you may have up to 10 years to file, it’s crucial to consult with an attorney as soon as possible. Medical records can be lost, witnesses’ memories fade, and early investigation strengthens your case. Don’t wait until the deadline approaches to seek legal guidance.
Compensation Available in Athetoid Cerebral Palsy Cases
Children with athetoid cerebral palsy often require extensive medical care, therapy, assistive equipment, and support services throughout their lives. New York law allows families to seek compensation for all economic and non-economic damages resulting from medical malpractice.
Types of Compensation
Settlement and Verdict Values
Cerebral palsy medical malpractice cases have among the highest settlement values of any personal injury claim type. According to national litigation data:
- Average verdict: $18,580,000
- Median verdict: $6,944,500
- Average settlement: $4,080,300
- Median settlement: $2,130,000
Nearly 70% of cerebral palsy cases are resolved through settlement rather than trial. The specific value of any case depends on factors including the severity of the child’s condition, the clarity of medical negligence, the child’s life expectancy, and the anticipated lifetime cost of care.
Notable New York Settlements
Recent New York cases involving athetoid cerebral palsy caused by kernicterus (preventable jaundice) have resulted in substantial compensation:
- $8.5 million settlement in Albany for untreated jaundice leading to severe hyperbilirubinemia, kernicterus, and cerebral palsy
- $23 million settlement for a child with four-limb cerebral palsy, visual impairment, and profound deafness caused by unrecognized jaundice
- $13 million settlement in New Jersey (applicable to NY law) for delayed cesarean section despite fetal distress from placental abruption
These substantial settlements reflect the lifetime costs of caring for a child with severe disabilities and the preventable nature of the medical errors involved.
Taking Action: Next Steps for New York Families
If your child has been diagnosed with athetoid cerebral palsy and you suspect medical negligence may have played a role, taking prompt action protects your family’s legal rights and your child’s future.

Frequently Asked Questions
What is the difference between athetoid and spastic cerebral palsy?
Athetoid (dyskinetic) cerebral palsy is characterized by involuntary, writhing movements and fluctuating muscle tone due to damage to the basal ganglia. Spastic cerebral palsy involves increased muscle stiffness and rigidity caused by damage to the motor cortex or white matter. While spastic CP is the most common type (70-80% of cases), athetoid CP accounts for 12-14% of cases and presents with distinctly different movement patterns.
Can athetoid cerebral palsy be prevented?
While not all cases are preventable, many instances of athetoid cerebral palsy result from preventable medical errors. Proper monitoring during labor and delivery can detect fetal distress early enough to prevent oxygen deprivation. Prompt diagnosis and treatment of newborn jaundice prevents kernicterus, one of the leading preventable causes of athetoid CP. Timely cesarean sections when medically indicated and proper management of maternal infections also reduce risk significantly.
How long do I have to file a birth injury lawsuit in New York?
Under New York CPLR §208, families have until the child’s 10th birthday to file a medical malpractice claim for birth injuries. The standard 2.5-year statute of limitations is tolled (paused) during infancy. However, if your child was born at a municipal hospital (such as NYC Health + Hospitals), you must file a Notice of Claim within 90 days of the injury. Despite the extended time limit, consulting an attorney early is crucial for preserving evidence and building a strong case.
What is kernicterus and how does it cause athetoid cerebral palsy?
Kernicterus is a type of brain damage caused by severe, untreated newborn jaundice. When bilirubin levels become toxic, the substance can cross into brain tissue and deposit in the basal ganglia—the exact area that controls movement. This damage results in athetoid cerebral palsy. Kernicterus is highly preventable through routine bilirubin monitoring and phototherapy or exchange transfusion when levels are elevated. Failure to diagnose and treat jaundice appropriately is a common form of medical negligence.
What compensation can I receive for my child’s athetoid cerebral palsy?
New York law allows families to recover compensation for past and future medical expenses, future lost wages, pain and suffering, and loss of enjoyment of life. This includes the lifetime costs of therapy, medications, surgeries, assistive equipment, home modifications, and specialized care. According to national data, the median settlement for cerebral palsy cases is $2.13 million, with average verdicts reaching $18.58 million. New York cases involving preventable kernicterus have settled for $8.5 million to $23 million.
How do I prove medical malpractice caused my child’s condition?
Proving medical malpractice requires establishing four elements: (1) the healthcare provider owed a duty of care, (2) they breached the standard of care, (3) the breach directly caused injury, and (4) damages resulted. This requires expert testimony from qualified medical professionals who review your records and explain how providers departed from accepted medical standards. Birth injury attorneys work with obstetricians, neonatologists, neurologists, and other specialists to analyze the medical evidence and build a compelling case.
Will my child’s athetoid cerebral palsy get worse over time?
Athetoid cerebral palsy is a nonprogressive condition, meaning the brain damage does not worsen over time. However, the physical manifestations may change as a child grows and develops. Some symptoms may become more apparent with age, while others may improve with therapy. Secondary complications such as joint problems, pain, or musculoskeletal deformities can develop over time due to the constant involuntary movements, which is why ongoing medical care and physical therapy are essential.
What is the life expectancy for children with athetoid cerebral palsy?
Life expectancy for children with athetoid cerebral palsy varies widely depending on the severity of the condition and associated complications. According to medical research, dyskinetic cerebral palsy shows a higher rate of early mortality compared to other subtypes, primarily due to respiratory complications. However, many individuals with milder forms live well into adulthood with proper medical care, therapy, and support. Factors affecting life expectancy include the presence of intellectual disabilities, seizures, feeding difficulties, and the quality of ongoing medical management.
Understanding Your Rights Under New York Law
New York’s medical malpractice laws are designed to protect families whose children suffer preventable birth injuries. The legal framework recognizes that athetoid cerebral palsy often results from medical errors that violate accepted standards of care.
New York CPLR 1411: Comparative Fault
Even if healthcare providers attempt to blame the injury partially on other factors, New York’s comparative fault rule (CPLR 1411) allows you to recover compensation as long as your child’s injury was not entirely your fault. The court determines each party’s percentage of responsibility and adjusts damages accordingly.
Certificate of Merit Requirement
Under New York CPLR §3012-a, plaintiffs must file a Certificate of Merit from a qualified medical expert attesting that the case has merit. This requirement helps ensure that only legitimate claims proceed through the court system. Experienced birth injury attorneys maintain relationships with respected medical experts who can provide these certifications.
The Legal Process
Birth injury medical malpractice cases typically follow this timeline:
- Free Consultation: Attorney evaluates your case and reviews medical records (no cost)
- Investigation: Legal team and medical experts thoroughly analyze the evidence (2-6 months)
- Filing Lawsuit: Complaint filed in court with Certificate of Merit
- Discovery: Both sides exchange information, take depositions, and gather evidence (6-18 months)
- Expert Reports: Medical experts provide detailed opinions on standard of care and causation
- Settlement Negotiations: Most cases (70%) settle before trial
- Trial: If settlement cannot be reached, the case goes to jury trial
While the process can take 2-4 years from filing to resolution, experienced attorneys work diligently to secure fair compensation as efficiently as possible.
Why Early Legal Consultation Matters
Although New York law provides up to 10 years to file a birth injury claim, consulting an attorney soon after diagnosis offers significant advantages:
- Evidence Preservation: Medical records can be lost or destroyed; early action ensures documentation is preserved
- Witness Memory: Healthcare providers’ memories fade over time; early interviews capture fresh recollections
- Expert Analysis: Medical experts need time to thoroughly review complex birth injury cases
- Financial Planning: Understanding potential compensation helps families plan for their child’s care needs
- Peace of Mind: Knowing your legal rights and options reduces uncertainty during a difficult time
Most birth injury attorneys offer free initial consultations and work on a contingency fee basis, meaning you pay nothing unless they recover compensation for your family. This arrangement makes quality legal representation accessible regardless of your financial situation.
Conclusion: Protecting Your Child’s Future
Athetoid cerebral palsy is a lifelong condition that requires extensive medical care, therapy, and support. When this condition results from preventable medical errors during pregnancy, labor, or delivery, New York law provides families with the right to pursue justice and secure the resources their children need.
Understanding the medical aspects of athetoid cerebral palsy—from its causes in basal ganglia damage to its characteristic involuntary movements—helps families recognize when medical negligence may have played a role. Whether the injury stemmed from untreated kernicterus, oxygen deprivation during labor, or delayed emergency intervention, families deserve accountability and compensation.
With up to 10 years to file a claim under New York law, families have time to carefully evaluate their legal options. However, early consultation with a qualified birth injury attorney preserves critical evidence and strengthens your case. Most cerebral palsy lawsuits result in substantial settlements, with recent New York cases involving athetoid CP reaching $8.5 million to $23 million.
If your child has been diagnosed with athetoid or dyskinetic cerebral palsy, don’t face this journey alone.
