Understanding Eclampsia Seizures and Brain Injury
Eclampsia represents one of the most dangerous complications of pregnancy, characterized by the onset of seizures in women with preeclampsia. When medical professionals fail to prevent the progression from preeclampsia to eclampsia, the consequences can be devastating for both mother and baby. According to the World Health Organization, eclampsia is responsible for approximately 46,000 maternal deaths per year globally and remains one of the leading causes of maternal mortality [Source: WHO, 2024].
In New York, families affected by eclamptic seizures and resulting brain injuries may have legal recourse when medical negligence contributed to preventable harm. This comprehensive guide examines how eclampsia causes brain damage, the medical standard of care that should prevent seizures, and the legal options available to affected families in New York State.

What Is Eclampsia and How Does It Cause Seizures?
Eclampsia is defined as the new onset of seizures or coma in a pregnant woman with preeclampsia who has no prior history of seizure disorders. While preeclampsia affects approximately 2-8% of pregnancies worldwide, only about 1 in 200 cases of preeclampsia progress to eclampsia when properly managed [Source: NCBI StatPearls, 2024].
The condition typically develops after the 20th week of pregnancy, though it can occur during labor, delivery, or even in the postpartum period. The seizures associated with eclampsia result from severe hypertension and the resulting effects on cerebral blood vessels.
The Progression from Preeclampsia to Eclampsia
Preeclampsia is characterized by high blood pressure (systolic 140 mm Hg or higher, or diastolic 90 mm Hg or higher) along with signs of organ damage, most commonly proteinuria (protein in the urine). When preeclampsia advances to its severe form and is not adequately treated, the risk of eclamptic seizures increases dramatically.
Warning signs that preeclampsia may progress to eclampsia include:
- Severe headaches: Persistent headaches unresponsive to medication
- Visual disturbances: Blurred vision, seeing spots, or temporary vision loss
- Upper abdominal pain: Pain under the ribs on the right side
- Severe hypertension: Blood pressure readings of 160/110 mm Hg or higher
- Altered mental status: Confusion, agitation, or decreased consciousness
How Eclamptic Seizures Cause Brain Damage
Eclamptic seizures can cause brain injury through several interconnected mechanisms. Understanding these pathways is essential for both medical treatment and legal claims involving negligent care.
Posterior Reversible Encephalopathy Syndrome (PRES)
Research published in the American Journal of Obstetrics and Gynecology found that posterior reversible encephalopathy syndrome (PRES) occurs in 46 of 47 patients with eclampsia, representing approximately 98% of cases [Source: AJOG, 2013]. A systematic review found the pooled prevalence of PRES in eclampsia patients ranges from 66% to 100% [Source: Journal of Hypertension in Pregnancy, 2023].
PRES is a neurological condition characterized by:
- Vasogenic edema: Fluid accumulation in brain tissue, particularly in the parietal and occipital lobes
- Blood-brain barrier disruption: Breakdown of the protective barrier surrounding the brain
- Cerebral hyperperfusion: Excessive blood flow to the brain due to failed autoregulation
While PRES is often described as reversible, delays in treatment can lead to permanent brain damage, including intracranial hemorrhage (occurring in approximately 11.2% of PRES cases) and maternal death (5.3%) [Source: PMC Systematic Review, 2023].
Oxygen Deprivation During Seizures
During an eclamptic seizure, the mother’s breathing may become compromised, leading to reduced oxygen delivery to both maternal and fetal brain tissue. Prolonged or repeated seizures can cause hypoxic-ischemic encephalopathy (HIE) in the baby if delivery is not expedited.
| Brain Injury Mechanism | Affected Party | Potential Outcomes |
|---|---|---|
| PRES / Cerebral Edema | Mother | Cognitive deficits, vision problems, stroke, death |
| Intracranial Hemorrhage | Mother | Permanent disability, death (accounts for 40% of maternal deaths) |
| Hypoxic-Ischemic Encephalopathy | Infant | Cerebral palsy, developmental delays, seizure disorders |
| Placental Abruption | Infant | Fetal distress, brain damage, stillbirth |
The Medical Standard of Care for Preventing Eclampsia
Medical providers have a clear duty to identify preeclampsia early and take appropriate steps to prevent progression to eclampsia. The American College of Obstetricians and Gynecologists (ACOG) has established specific guidelines that represent the accepted standard of care.
Magnesium Sulfate: The Primary Seizure Prevention
Magnesium sulfate is the drug of choice for both preventing and treating eclamptic seizures. According to ACOG guidelines, magnesium sulfate should be administered to patients with preeclampsia with severe features, which includes:
- Severe hypertension: Systolic blood pressure of 160 mm Hg or higher, or diastolic of 110 mm Hg or higher, on two occasions at least four hours apart
- Thrombocytopenia: Platelet count below 100,000/mm3
- Impaired liver function: Liver enzymes more than twice the upper limit of normal
- Renal insufficiency: Serum creatinine greater than 1.1 mg/dL
- Pulmonary edema: Fluid accumulation in the lungs
- New onset headache or visual disturbances: Unresponsive to medication
The standard dosing protocol includes a loading dose of 4-6 grams administered intravenously over 15-20 minutes, followed by a maintenance infusion of 1-2 grams per hour [Source: ACOG Practice Bulletin]. Research demonstrates that magnesium sulfate reduces the risk of eclampsia by more than 50%.
Additional Standard of Care Requirements
Monitoring Requirements
- Frequent blood pressure measurements
- Regular laboratory testing (liver function, platelets, kidney function)
- Continuous fetal heart rate monitoring
- Assessment of warning symptoms
- Physical examinations every 4-6 hours
Treatment Interventions
- Antihypertensive medications (labetalol, hydralazine, nifedipine)
- Magnesium sulfate for seizure prophylaxis
- Corticosteroids for fetal lung maturity if preterm
- Timely delivery planning
- Intensive maternal-fetal surveillance
Medical Negligence in Eclampsia Cases
When healthcare providers fail to meet the standard of care in managing preeclampsia and preventing eclampsia, they may be liable for medical malpractice. Research indicates that in 46% of maternal deaths due to preeclampsia and eclampsia, different management would reasonably have been expected to alter the outcome [Source: Pre-eclampsia Claims Data].
Common Forms of Negligence
Medical malpractice in eclampsia cases typically involves one or more of the following failures:
Failure to Diagnose Preeclampsia: Providers may miss the diagnosis by failing to monitor blood pressure adequately, not ordering urine protein tests, or dismissing warning symptoms as normal pregnancy discomfort.
Failure to Recognize Severe Features: Even when preeclampsia is diagnosed, providers may fail to recognize when the condition has progressed to severe features that require immediate intervention.
Failure to Administer Magnesium Sulfate: The most preventable form of negligence occurs when providers do not administer magnesium sulfate prophylaxis to patients meeting criteria for severe preeclampsia.
Delayed Delivery: When preeclampsia becomes severe, timely delivery is often the only definitive treatment. Delays in performing cesarean sections or inducing labor can allow the condition to progress to eclampsia.
Inadequate Monitoring: Failure to perform required monitoring can result in missed warning signs that the condition is worsening.
| Type of Negligence | What Should Have Happened | Potential Consequence |
|---|---|---|
| Missed diagnosis | Regular BP monitoring, urine tests, symptom assessment | Condition progresses undetected |
| No magnesium sulfate | Administer prophylaxis when severe features present | Preventable seizures occur |
| Delayed delivery | Expedite delivery when maternal/fetal status deteriorates | Prolonged exposure to harmful conditions |
| Inadequate monitoring | Continuous fetal monitoring, regular maternal assessments | Warning signs missed |
| Premature discharge | Keep high-risk patients for observation | Eclampsia occurs outside hospital setting |
New York Medical Malpractice Laws for Eclampsia Brain Injury Claims
Families pursuing eclampsia-related brain injury claims in New York must understand the specific legal requirements that govern medical malpractice cases in the state.
Statute of Limitations in New York
New York has specific deadlines for filing medical malpractice lawsuits that vary depending on who was injured:
For Adult Patients (Mothers): The general statute of limitations for medical malpractice in New York is two years and six months from the date of the alleged malpractice or from the end of continuous treatment by the same provider for the same condition [Source: NY CPLR].
For Infant Brain Injuries: Under New York Civil Practice Law and Rules (CPLR) Section 208, there is an infancy toll that extends the deadline for minors. However, medical malpractice claims for children must be filed by the time the child reaches age 10 if the injury occurred during birth or early infancy [Source: NY CourtHelp].
Critical Deadline: If your child suffered brain injury due to eclampsia-related negligence at birth, the lawsuit must generally be filed before the child turns 10 years old. Do not delay in seeking legal consultation, as evidence can become harder to obtain over time.
Claims Against Public Hospitals in New York
If the negligent care occurred at a public hospital (such as those operated by NYC Health + Hospitals), special rules apply. A Notice of Claim must be filed within 90 days of the incident. This extremely short deadline makes immediate legal consultation essential.
Certificate of Merit Requirement
New York law requires that within 90 days of filing a medical malpractice lawsuit, the plaintiff must file a certificate of merit from a qualified medical expert. This expert must review the case and attest that there is a reasonable basis for the malpractice claim.
Damages Available in Eclampsia Brain Injury Cases
Victims of eclampsia-related brain injuries may be entitled to significant compensation for their losses. New York allows recovery for both economic and non-economic damages.
Economic Damages
These include quantifiable financial losses such as:
- Medical expenses: Past and future costs of treatment, therapy, medications, and medical equipment
- Rehabilitation costs: Physical therapy, occupational therapy, speech therapy
- Long-term care: Home health aides, assisted living, or nursing care
- Lost wages: Income lost due to the injury
- Lost earning capacity: Future income the victim will be unable to earn
Non-Economic Damages
These compensate for subjective losses including:
- Pain and suffering: Physical pain and emotional distress
- Loss of enjoyment of life: Inability to participate in activities previously enjoyed
- Loss of consortium: Impact on marital and family relationships
- Cognitive impairment: Loss of mental function and quality of life
Notable Verdicts and Settlements
Eclampsia and preeclampsia-related medical malpractice cases have resulted in substantial verdicts and settlements across the country:
- $35 million verdict (New York): In Lopez v. NYC Health Hospitals, an infant sustained brain damage and cerebral palsy due to failure to diagnose and treat preeclampsia
- $22.8 million verdict (2025): Family of a mother who died from brain hemorrhage due to eclampsia complications
- $17.1 million verdict (2025): Infant death due to failure to deliver early despite preeclampsia diagnosis
- $6.9 million settlement: Woman discharged prematurely twice with postpartum preeclampsia symptoms before death
Long-Term Effects of Eclampsia on Mothers and Infants
The consequences of eclampsia extend far beyond the immediate medical emergency. Research from the European Journal of Medical Research (2024) demonstrates that both mothers and their children face lasting neurological and cognitive challenges [Source: European Journal of Medical Research, 2024].
Maternal Long-Term Outcomes
Women who experience eclampsia may face:
- Cognitive deficits: Impairments in memory, executive function, and processing speed
- Increased cerebrovascular risk: Higher lifetime risk of stroke and cardiovascular disease
- Persistent white matter lesions: Brain imaging abnormalities detected years after the event
- Lower quality of life: Decreased physical and mental health-related quality of life
- Psychosocial effects: Depression, anxiety, and post-traumatic stress
Infant and Child Outcomes
Children exposed to eclampsia in utero or who suffered hypoxic injury due to maternal seizures may develop:
- Cerebral palsy: A group of permanent movement disorders
- Cognitive impairments: Learning disabilities and intellectual disabilities
- Autism spectrum disorder: Higher rates compared to unexposed children
- Attention deficit hyperactivity disorder (ADHD): Increased prevalence
- Seizure disorders: Epilepsy and other seizure conditions
- Developmental delays: Delays in reaching motor and cognitive milestones
Research Finding: According to a 2024 review in the European Journal of Medical Research, consistent findings indicate that preeclampsia and eclampsia are linked to impairments in maternal cognitive functions and psychosocial health, while offspring exposed in utero show cognitive deficits and alterations in brain connectivity.

Frequently Asked Questions
What is the difference between preeclampsia and eclampsia?
Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of organ damage, typically protein in the urine. Eclampsia is the progression of preeclampsia to include seizures or coma. While preeclampsia can often be managed, eclampsia represents a medical emergency that can cause permanent brain damage or death to both mother and baby. The key distinction is the presence of seizures in eclampsia.
Can eclampsia cause permanent brain damage?
Yes, eclampsia can cause permanent brain damage to both the mother and infant. Mothers may develop posterior reversible encephalopathy syndrome (PRES), intracranial hemorrhage, or stroke. Research shows that approximately 11.2% of PRES cases result in intracranial hemorrhage. Infants may suffer hypoxic-ischemic encephalopathy (HIE) leading to cerebral palsy and cognitive disabilities. Early treatment significantly improves outcomes, which is why delays in care can form the basis of malpractice claims.
How can eclampsia be prevented?
Eclampsia can be prevented through proper prenatal care, early detection of preeclampsia, and appropriate medical intervention. The primary prevention method is administering magnesium sulfate to patients with severe preeclampsia, which reduces seizure risk by more than 50%. Other preventive measures include regular blood pressure monitoring, laboratory testing, controlling severe hypertension with antihypertensive medications, and timely delivery when the condition becomes severe.
What is the statute of limitations for eclampsia malpractice claims in New York?
In New York, the general statute of limitations for medical malpractice is 2 years and 6 months from the date of the negligent act. For infant brain injuries caused by eclampsia, parents typically have until the child turns 10 years old to file a lawsuit. However, claims against public hospitals require a Notice of Claim within 90 days. Given these strict deadlines, families should consult with a qualified attorney as soon as possible.
What is PRES and how is it related to eclampsia?
PRES (Posterior Reversible Encephalopathy Syndrome) is a neurological condition that occurs in the vast majority of eclampsia cases, with studies showing prevalence of 66-100% in eclampsia patients. PRES is characterized by brain swelling (vasogenic edema), particularly in the parietal and occipital lobes, causing headaches, visual disturbances, altered consciousness, and seizures. While often reversible with prompt treatment, delayed care can result in permanent brain damage, hemorrhage, or death.
What compensation can families receive for eclampsia brain injuries?
Families may recover substantial compensation including medical expenses (past and future), rehabilitation costs, long-term care expenses, lost wages, lost earning capacity, pain and suffering, loss of enjoyment of life, and loss of consortium. Verdicts and settlements in eclampsia cases have ranged from hundreds of thousands to tens of millions of dollars. A New York case involving failure to treat preeclampsia resulted in a $35 million verdict for an infant with brain damage and cerebral palsy.
What are the warning signs that preeclampsia is progressing to eclampsia?
Warning signs include severe headaches that do not respond to medication, visual disturbances (blurred vision, seeing spots, temporary blindness), upper abdominal pain (especially under the right ribs), severe hypertension (160/110 mm Hg or higher), altered mental status or confusion, decreased urine output, and sudden swelling of the face and hands. Any of these symptoms in a pregnant woman with preeclampsia requires immediate medical attention.
Can I sue if my doctor failed to give me magnesium sulfate?
If you had severe preeclampsia and your healthcare provider failed to administer magnesium sulfate prophylaxis as required by ACOG guidelines, and you subsequently developed eclampsia causing injury to you or your baby, you may have grounds for a medical malpractice claim. The failure to follow established protocols for seizure prevention is a recognized form of medical negligence. An experienced medical malpractice attorney can evaluate whether the standard of care was breached in your specific case.
What happens to the baby during an eclamptic seizure?
During a maternal eclamptic seizure, the baby may experience reduced oxygen supply because the mother’s breathing becomes compromised and blood flow to the placenta may be affected. This can cause fetal distress and, if prolonged, hypoxic-ischemic encephalopathy (HIE) – a type of brain injury caused by oxygen deprivation. Eclampsia also increases the risk of placental abruption, where the placenta separates from the uterine wall, further compromising fetal oxygen supply. Emergency delivery is often necessary to protect the baby.
How long do I have to file a claim if my baby suffered brain injury from eclampsia in New York?
In New York, medical malpractice claims for birth injuries generally must be filed before the child reaches age 10, regardless of the standard infancy toll that would otherwise extend the deadline to age 20.5. This 10-year cap is specific to medical malpractice cases in New York. Additionally, if the injury occurred at a public hospital, a Notice of Claim must be filed within 90 days. Because of these strict deadlines and the complexity of medical evidence, families should seek legal consultation as soon as possible after discovering an injury may have been caused by negligence.
