Epilepsy during pregnancy: overview


Epilepsy (seizures) is relatively common among women of childbearing age. Around 15–30% of women may experience an increased risk of seizures during pregnancy, especially in the first trimester.

This condition can be stressful because it affects both:

  • The mother’s health

  • The baby’s safety

Some anti-seizure medications may increase the risk of birth defects, and children born to mothers with epilepsy may have a higher chance of developing seizures later in life.

Causes of seizures during pregnancy

Seizures in pregnant women may be triggered by:

  • Hormonal changes

  • Genetic history of epilepsy

  • Not taking medication as prescribed

  • Lack of sleep

  • Fatigue, nausea, and vomiting

  • Drug interactions (other medications affecting epilepsy treatment)

Symptoms of epilepsy in pregnancy

Seizures can occur suddenly and may include:

  • Headache

  • Dizziness

  • Mood or energy changes

  • Fainting or confusion

  • Memory problems

  • Limb shaking or tingling

  • Difficulty breathing

Risks for the mother

Most women with epilepsy have healthy pregnancies, but complications can occur, such as:

  • Placental abruption (placenta separating from the uterus)

  • Miscarriage due to trauma during seizures

  • Premature birth

  • Increased risk of sudden death (rare but serious)

Good control before pregnancy matters:
If no seizures occur for 9 months before pregnancy, the risk during pregnancy is lower.

Risks for the baby

Some risks depend on medication type and dosage:

  • Birth defects (especially neural tube defects)

  • Heart abnormalities

  • Skeletal issues

  • Slower fetal heart rate

  • Developmental delays (speech, cognition, memory)

  • Increased risk of autism spectrum disorders

  • Delayed walking or talking

Treatment and management

1. Anti-seizure medications

  • Necessary to control seizures

  • Must be carefully adjusted by a doctor

  • High doses or multiple drugs increase risks

2. Folic acid supplements

  • Very important during pregnancy

  • Helps reduce risk of birth defects

  • Higher doses are often recommended for women with epilepsy

3. Healthy lifestyle

  • Eat nutritious food

  • Take prenatal vitamins

  • Limit caffeine

  • Avoid smoking

  • Get enough sleep

4. Regular medical check-ups

  • Frequent doctor visits are essential

  • Includes:

    • Blood tests (to monitor medication levels)

    • Ultrasounds (to monitor baby’s growth)

Important advice

  • Always consult a doctor before pregnancy if you have epilepsy

  • Never stop medication without medical guidance

  • With proper care, most women with epilepsy can have healthy pregnancies and babies

Key takeaway

Epilepsy during pregnancy requires careful management, but it is not a barrier to a healthy pregnancy. With the right treatment, monitoring, and lifestyle, risks can be significantly reduced.
