At 38, can Parkinson’s disease affect my sister’s pregnancy?

Question

Hello doctor,

My sister, a 38 year old, recently got diagnosed with early-stage Parkinson’s disease, and she is overwhelmed with questions, especially because she and her husband were planning to start trying for a baby this year. She is worried about whether Parkinson’s can affect fertility, pregnancy, or the baby's development. She also wants to know if continuing medications like Levodopa or Dopamine agonists are safe during conception and pregnancy. Her periods have also become irregular lately.

Could that be related to the disease or the medication?
She feels so conflicted about delaying family planning, but she also does not want to jeopardize her health or a potential pregnancy.
What should she prioritize in terms of managing Parkinson’s while still keeping pregnancy in mind?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Parkinson’s disease itself usually does not directly reduce fertility, but stress, fatigue, and certain medications can affect menstrual regularity. Dopamine agonists may sometimes cause your hormonal changes, but irregular cycles could also be from unrelated gynecologic or endocrine causes, so this should be checked separately.

When planning pregnancy, medication safety is key for you. Levodopa is generally considered the safest Parkinson’s drug during pregnancy if needed, though careful dose monitoring is important. Dopamine agonists, Monoamine oxidase B (MAO-B) inhibitors, and some other Parkinson’s medicines are usually avoided due to limited safety data.

The safest approach is to work closely with both her neurologist and obstetrician to review her medication list before conception, ideally switching to a pregnancy-compatible regimen and achieving stable symptom control.

She should prioritize keeping her Parkinson’s well-managed so she remains mobile, strong, and able to cope with the physical demands of pregnancy and newborn care. Pre-pregnancy counseling, optimization of nutrition and exercise, and building a strong support system at home will help balance her health with family planning goals.

I hope this information helps you.
