Neonatal Stroke and Perinatal Brain Injury Negligence

Types of Perinatal Stroke

Perinatal strokes are classified by mechanism and timing:

• Arterial ischemic stroke (AIS): The most common type, caused by a blockage of an artery supplying blood to the brain. This can result from a blood clot (thrombus or embolus) traveling to the brain.
• Cerebral sinovenous thrombosis (CSVT): A clot in the venous drainage system of the brain, causing backed-up blood and hemorrhage.
• Perinatal hemorrhagic stroke: Bleeding into the brain tissue, often associated with trauma during delivery (e.g., from forceps or vacuum extraction), clotting disorders, or rupture of a vascular malformation.
• Fetal stroke: Occurs before birth, typically detected when seizures or developmental delays appear in the first days or months of life.

How Neonatal Strokes Happen

The causes of neonatal stroke are diverse and often involve a combination of factors:

- Placental abnormalities: Clots can form in the placenta and travel through the umbilical vein to the baby's brain. The placenta is the most common source of emboli in perinatal arterial ischemic stroke.

- Birth trauma: Instrumental deliveries using forceps or vacuum extraction can cause mechanical injury to the baby's head and the blood vessels within, leading to hemorrhagic stroke.

- Perinatal asphyxia: Oxygen deprivation during labor and delivery can damage blood vessels and contribute to stroke.

- Maternal conditions: Preeclampsia, chorioamnionitis (intra-amniotic infection), maternal thrombophilia (clotting disorders), and autoimmune conditions can increase the baby's stroke risk.

- Neonatal conditions: Polycythemia (too many red blood cells), dehydration, congenital heart disease, and infections (like meningitis) can contribute to stroke.

- Clotting disorders: Genetic or acquired thrombophilias in either the mother or baby can predispose to thrombotic events.

Risk Factors and Warning Signs

Risk factors for neonatal stroke include:

• Preeclampsia and eclampsia
• Chorioamnionitis (intra-amniotic infection)
• Prolonged or difficult labor
• Instrumental delivery (forceps or vacuum)
• Birth asphyxia or low Apgar scores
• Maternal thrombophilia or autoimmune disease
• Congenital heart disease in the baby
• Neonatal sepsis or meningitis
• Polycythemia (elevated red blood cell count)
• Dehydration in the newborn period

Warning Signs of Neonatal Stroke

The clinical presentation of neonatal stroke varies, and in some cases, the stroke is 'silent' — not recognized until developmental delays or seizures emerge months later. However, warning signs that should prompt immediate evaluation include:

• Seizures: The most common presenting sign of neonatal stroke. Neonatal seizures can be subtle — including rhythmic twitching of one limb, lip-smacking, or bicycling movements of the legs.
• Apnea: Pauses in breathing, sometimes associated with seizures.
• Lethargy or altered consciousness: The baby is unusually sleepy or difficult to arouse.
• Poor feeding: Difficulty latching, weak suck, or inability to feed.
• Hypotonia: Floppiness or low muscle tone, particularly on one side.
• Hemiparesis: Weakness on one side of the body — though this is often not recognized until later in infancy.
• Abnormal eye movements: Nystagmus or other gaze abnormalities.

The Standard of Care for Diagnosis

When a neonatal stroke is suspected — either because of clinical signs like seizures or because of risk factors — the standard of care requires prompt neuroimaging:

• Cranial ultrasound: Often the first imaging study in the NICU. It is portable and safe but may miss early ischemic strokes, particularly in the posterior circulation.
• MRI of the brain: The gold standard for diagnosing neonatal stroke. Diffusion-weighted imaging (DWI) can detect ischemic injury within hours of onset. MR angiography (MRA) can identify vascular abnormalities.
• CT scan: May be used in emergencies to detect hemorrhage but exposes the baby to radiation and is less sensitive than MRI for ischemic stroke.
• EEG (electroencephalogram): To detect seizures, including subclinical seizures that have no visible signs but still cause brain injury.
• Coagulation workup: Blood tests for thrombophilia and clotting disorders in both the baby and the mother.
• Echocardiogram: To evaluate for congenital heart disease or patent foramen ovale that could allow clots to bypass the lungs and reach the brain.

When a Neonatal Stroke Is Medical Malpractice

Not all neonatal strokes are preventable, and not all cases are malpractice. However, neonatal stroke may constitute medical malpractice when:

• Risk factors were not recognized or managed: For example, preeclampsia was not treated, chorioamnionitis was not diagnosed, or a thrombophilia was not identified despite a family history.
• Birth trauma caused the stroke: The stroke resulted from improper use of forceps or vacuum extraction, or from excessive force during a difficult delivery.
• Asphyxia was not prevented: The stroke resulted from prolonged oxygen deprivation during labor that should have been recognized on fetal monitoring and addressed with prompt delivery.
• The stroke was not diagnosed promptly: Seizures or other neurological signs were not recognized, or neuroimaging was delayed, allowing ongoing injury or preventable complications.
• Seizures were not treated: Subclinical seizures were identified on EEG but not treated with anticonvulsant medication, allowing ongoing brain injury.
• Follow-up was not provided: A baby with risk factors or early signs was discharged without appropriate follow-up and neurodevelopmental monitoring.

Long-Term Consequences

The long-term consequences of neonatal stroke depend on the size and location of the stroke and the timeliness of intervention:

• Hemiplegic or hemiparetic cerebral palsy: The most common long-term outcome — weakness or paralysis on one side of the body. Approximately 30-50% of children with perinatal stroke develop cerebral palsy.
• Epilepsy: Seizure disorders that may require lifelong anticonvulsant medication. Occurs in approximately 20-30% of children after perinatal stroke.
• Cognitive impairment: Ranging from mild learning disabilities to severe intellectual disability.
• Sensory deficits: Visual field cuts (hemianopia), sensory loss on the affected side.
• Speech and language delays: Particularly if the stroke affects the dominant hemisphere.
• Behavioral and psychological issues: ADHD, anxiety, and social difficulties are more common in children with perinatal stroke.
• Motor planning deficits: Difficulty with coordination, fine motor skills, and activities of daily living.

Building a Neonatal Stroke Malpractice Case

Building a neonatal stroke malpractice case requires deep medical expertise. At MDLaw Firm, we:

1. Obtain and review all medical records — prenatal, labor and delivery, neonatal, neurology, and neuroimaging studies.

2. Engage expert consultants — including pediatric neurologists, neuroradiologists, maternal-fetal medicine specialists, and sometimes hematologists — to evaluate whether the standard of care was breached and whether the breach caused the stroke.

3. Establish causation — determining whether the stroke was caused by a preventable factor (birth trauma, unmanaged asphyxia, untreated infection) or was a non-preventable event.

4. Calculate damages — working with lifecare planners to project the cost of future medical care, therapy, special education, and lost earning capacity.

5. Pursue litigation — filing the case, conducting discovery, taking depositions, and preparing for trial.

We handle neonatal stroke cases on a contingency fee basis — you pay nothing unless we secure compensation for your family.

New York Statute of Limitations

Under CPLR § 214-a, the general statute of limitations for medical malpractice is 2.5 years. Under the infant tolling rule (CPLR § 208), the statute is tolled for minors until age 18, meaning the injured child has until approximately age 20 to file a claim. A parent's derivative claim for medical expenses is subject to the standard 2.5-year deadline. New York does not cap non-economic damages, and a certificate of merit (CPLR § 3012-a) is required.

Frequently Asked Questions

The value of a medical malpractice case in New York depends on several factors, including the severity of the injury, the strength of liability evidence, and the economic and non-economic damages involved. New York is one of the few states with no caps on medical malpractice damages, meaning there is no artificial limit on what you can recover. Below are typical settlement ranges based on injury severity.
