What this trial studies

This pilot study aims to evaluate the feasibility of longitudinal neurodevelopmental assessments for fetuses and infants exposed to Lyme disease in utero. Pregnant participants diagnosed with Lyme disease or Post-Treatment Lyme Disease Syndrome (PTLDS) will be monitored throughout their pregnancy, and their infants' development will be assessed from birth until 18 months of age. The study seeks to understand the impact of in utero Lyme disease exposure on early childhood neurodevelopment, which is crucial for developing appropriate follow-up and treatment guidelines. This foundational research will inform larger studies aimed at addressing this significant knowledge gap.

Who should consider this trial

Good fit: Ideal candidates include pregnant women diagnosed with Lyme disease or PTLDS within three years prior to their pregnancy.

Not a fit: Patients who do not have a diagnosis of Lyme disease or PTLDS, or those unable to participate due to health issues preventing MRI, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of neurodevelopmental outcomes in children exposed to Lyme disease during pregnancy.

How similar studies have performed: While there is limited research specifically on neurodevelopmental outcomes following in utero Lyme disease exposure, this pilot study addresses a priority research area that has not been extensively explored.
