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.

Would that have anything to do with the disease or the drug?
She is so torn between putting off having children and wanting to avoid compromising her health or a possible pregnancy.
How can she balance both her health with Parkinson’s and pregnancy?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com

Your question has been seen by me, and I can appreciate your apprehensions.

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 a 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.

It is important that she maintains her Parkinson’s disease under control so as to be able to move around, stay physically fit, and endure the physical strain associated with pregnancy and taking care of a baby. Proper pre-pregnancy counseling, nutritional optimization, and exercise, along with having a good support network, will contribute towards this.

I hope the above information is helpful for you.

Thank you.
