Experiencing seizures during pregnancy can be concerning for expectant mothers. Whether you have been diagnosed with epilepsy before conception or are experiencing seizures for the first time during pregnancy, understanding how to manage this condition is crucial for both your health and your baby’s well-being. This comprehensive guide provides essential information about seizures during pregnancy, helping you navigate this important journey with confidence.
Understanding Seizures and Pregnancy
Seizures during pregnancy occur in approximately 0.3% to 0.5% of all pregnancies. For women with epilepsy, pregnancy represents a unique challenge that requires careful planning and monitoring. The good news is that the vast majority of women with seizure disorders deliver healthy babies when they receive appropriate medical care.
A seizure is caused by abnormal electrical activity in the brain that can result in various symptoms, from brief lapses in awareness to convulsions. During pregnancy, managing seizures becomes more complex due to hormonal changes, altered medication metabolism, and concerns about fetal safety.
Can Epilepsy Affect Your Ability to Conceive?
Many women wonder whether having epilepsy or experiencing seizures will impact their fertility. Generally, epilepsy itself does not directly affect your ability to become pregnant. However, certain factors related to seizure management may influence fertility:
- Some anti-seizure medications may interact with hormonal contraceptives, reducing their effectiveness
- Certain seizure medications might affect reproductive hormones
- Seizure activity in specific brain regions may occasionally impact hormonal regulation
If you are planning to become pregnant, discuss your medications with your healthcare provider well in advance. They can help you optimize your treatment plan to support both seizure control and fertility.
How Pregnancy Affects Seizure Activity
Every woman’s experience with seizures during pregnancy is unique. Research shows that:
- About 50-70% of women experience no change in seizure frequency during pregnancy
- 15-30% may notice a decrease in seizures
- 15-30% may experience an increase in seizure activity
Several factors can influence seizure frequency during pregnancy, including hormonal fluctuations, stress, sleep deprivation, changes in medication metabolism, and morning sickness that may interfere with medication absorption.
Risks of Seizures During Pregnancy
While many women with seizure disorders have healthy pregnancies, it is important to understand potential risks:
Risks to the Mother
- Physical injury from falls during seizures
- Increased risk of pregnancy complications
- Status epilepticus (prolonged seizures requiring emergency treatment)
- Emotional stress and anxiety
Risks to the Baby
- Temporary decrease in oxygen supply during maternal seizures
- Slowing of fetal heart rate during seizures
- Slightly increased risk of preterm birth
- Low birth weight in some cases
- Placental abruption following maternal injury
- Small increased risk of developmental delays
The type and severity of seizures significantly impact these risks. Generalized tonic-clonic seizures (grand mal seizures) pose more concern than focal or absence seizures. Working closely with your healthcare team helps minimize these risks.
Medication Management During Pregnancy
One of the most challenging aspects of managing seizures during pregnancy involves medication decisions. You and your healthcare provider must balance seizure control against potential effects on fetal development.
Understanding Medication Risks
Anti-seizure medications carry varying levels of risk during pregnancy. Potential concerns include an increased risk of birth defects, particularly with certain medications and higher doses, greater risk when taking multiple medications simultaneously, and possible effects on fetal growth and development.
However, uncontrolled seizures during pregnancy often pose greater risks to both mother and baby than medication exposure. Most experts agree that maintaining seizure control is the priority.
Working With Your Healthcare Provider
Before you attempt to become pregnant, consult with your healthcare provider about your medication regimen. Never stop or adjust your medication without medical supervision. Your provider may recommend switching to medications with better safety profiles during pregnancy, using the lowest effective dose, or considering medication changes if you have been seizure-free for an extended period.
Throughout your pregnancy, your medication levels will be monitored regularly, as pregnancy affects how your body metabolizes medications. Dose adjustments may be necessary to maintain therapeutic levels.
Pre-Pregnancy Planning
Ideally, pregnancy planning should begin several months before conception. This allows time to optimize your health and seizure management.
Steps to Take Before Conception
- Schedule a preconception consultation with your neurologist and obstetrician
- Ensure your seizures are well-controlled for at least several months
- Review and optimize your medication regimen
- Begin taking prenatal vitamins with folic acid
- Achieve a healthy weight
- Address any other health concerns
- Quit smoking and avoid alcohol
- Establish healthy sleep patterns
The Importance of Folic Acid
Folic acid supplementation is crucial for all pregnant women, but especially for those taking anti-seizure medications. Folic acid helps prevent neural tube defects, which affect the brain and spinal cord development.
Women with epilepsy should take higher doses of folic acid than the standard recommendation. Your healthcare provider may recommend 0.4 to 5 milligrams daily, starting at least three months before conception. The specific dose depends on your medication and risk factors.
Prenatal Care and Monitoring
Pregnancy with a seizure disorder is typically classified as high-risk, requiring more frequent monitoring and specialized care.
What to Expect at Prenatal Visits
- More frequent appointments than standard prenatal care
- Regular monitoring of medication blood levels
- Frequent blood pressure and weight checks
- Additional ultrasounds to monitor fetal growth and development
- Specialized testing such as detailed anatomy scans and fetal echocardiograms
- Coordination between your obstetrician, neurologist, and other specialists
Fetal Monitoring
Your baby will be monitored closely throughout pregnancy through ultrasound examinations to track growth and development, specialized scans to check for birth defects, and fetal movement counting in the third trimester. In some cases, additional monitoring with non-stress tests or biophysical profiles may be recommended.
Managing Seizures During Pregnancy
Even with optimal management, seizures may occur during pregnancy. Having a plan in place is essential.
If You Have a Seizure
- Contact your healthcare provider immediately after any seizure
- Keep a detailed seizure diary noting frequency, duration, and triggers
- Seek emergency care for seizures lasting longer than five minutes
- Report any changes in seizure pattern or frequency
- Your provider may need to adjust your medication
Safety Precautions
Taking safety precautions can help prevent injury if seizures occur:
- Avoid activities where a seizure could cause serious harm, such as swimming alone or climbing ladders
- Take showers instead of baths
- Use guards around fireplaces and heaters
- Consider your state’s driving restrictions for people with seizures
- Inform family members and friends about seizure first aid
Lifestyle Management
Healthy lifestyle choices support seizure control and overall pregnancy health.
Sleep
Sleep deprivation is a common seizure trigger. Prioritize getting 7-9 hours of sleep nightly. Maintain a consistent sleep schedule, create a relaxing bedtime routine, and ask your partner to help with nighttime responsibilities when possible.
Stress Management
Stress can trigger seizures and complicate pregnancy. Consider prenatal yoga, meditation and deep breathing exercises, pregnancy support groups, and counseling if needed.
Nutrition
A balanced diet supports both seizure control and fetal development. Eat regular meals to maintain stable blood sugar, stay well-hydrated, and limit caffeine, which may interfere with seizure medications and trigger seizures in some people.
Labor and Delivery
Most women with seizure disorders have uncomplicated vaginal deliveries. Seizures during labor are uncommon, occurring in only 1-2% of deliveries.
Delivery Planning
- Discuss your delivery plan with your healthcare team well before your due date
- Ensure your obstetrician and hospital staff are aware of your seizure disorder
- Continue taking your anti-seizure medication during labor
- Have a plan in place in case a seizure occurs during delivery
- Your baby may receive vitamin K at birth to prevent rare bleeding complications
If a Seizure Occurs During Labor
If you experience a seizure during labor, your medical team will provide immediate treatment. Brief seizures typically do not require changing the delivery plan. However, prolonged seizures may necessitate emergency cesarean delivery to protect both you and your baby.
Postpartum Considerations
The weeks following delivery require continued attention to seizure management.
Medication Adjustments
If your medication dosage was increased during pregnancy, your healthcare provider will likely recommend returning to your pre-pregnancy dose shortly after delivery. This helps maintain appropriate medication levels as your body returns to its non-pregnant state.
Breastfeeding
Most women with seizure disorders can safely breastfeed. While anti-seizure medications do pass into breast milk in small amounts, the benefits of breastfeeding generally outweigh potential risks. Discuss breastfeeding with your healthcare provider before delivery. They may recommend timing your medication dose to minimize the amount in breast milk or monitoring your baby for any concerning symptoms.
Newborn Care Safety
Taking precautions when caring for your newborn can prevent injury if you have a seizure:
- Change diapers on the floor rather than on a changing table
- Feed your baby while sitting on the floor with pillows around you
- Consider using a firm baby carrier for holding your infant
- Avoid bathing your baby alone if possible
- Ensure another adult is present when you care for your baby, especially during the early weeks
Long-Term Outcomes
Research provides reassuring information about children born to mothers with seizure disorders. Most children develop normally without complications. The slight increase in risk for birth defects and developmental delays is small and varies based on specific medications and seizure control. Children are not more likely to develop epilepsy unless there is a genetic component to your condition.
Emotional and Psychological Support
Managing seizures during pregnancy can be emotionally challenging. It is normal to experience anxiety about your health and your baby’s well-being, concerns about medication safety, worry about having a seizure while caring for your baby, and stress from frequent medical appointments.
Seeking support can help. Consider joining pregnancy support groups or epilepsy support communities, working with a counselor or therapist experienced in high-risk pregnancies, and connecting with other mothers who have managed seizures during pregnancy. Remember to communicate openly with your partner and healthcare team about your concerns.
When to Seek Emergency Care
Contact your healthcare provider or seek emergency care if you experience a seizure lasting longer than five minutes, multiple seizures in a short period, difficulty breathing after a seizure, injury during a seizure, or a seizure that differs significantly from your usual pattern. Additionally, seek prompt medical attention for any pregnancy warning signs such as severe headaches, vision changes, severe abdominal pain, or decreased fetal movement.
Working With Your Healthcare Team
Successful management of seizures during pregnancy requires collaboration among multiple specialists. Your team may include an obstetrician, preferably one specializing in high-risk pregnancies, a neurologist with expertise in epilepsy, your primary care provider, a genetic counselor if there are concerns about hereditary factors, and a pediatrician familiar with caring for infants exposed to anti-seizure medications.
Maintain open communication with all members of your healthcare team. Keep all appointments, report any changes in your condition promptly, and ask questions about anything you do not understand. Your active participation in your care is essential for the best outcomes.
Looking Forward
While managing seizures during pregnancy requires careful planning and monitoring, most women with seizure disorders successfully carry pregnancies to term and deliver healthy babies. Advances in medication safety, improved prenatal monitoring, and better understanding of epilepsy during pregnancy continue to improve outcomes.
By working closely with your healthcare team, maintaining good seizure control, and following recommended precautions, you can significantly reduce risks and enjoy a healthy pregnancy. Remember that you are not alone in this journey, and with proper support and medical care, you can look forward to welcoming your baby.
If you are considering pregnancy or are already pregnant and have concerns about seizures, schedule a consultation with your healthcare provider as soon as possible. Early planning and intervention provide the best foundation for a successful pregnancy outcome.
