Epigenetics and Neurological Disorders in ART

Area of Science:

• Reproductive medicine
• Developmental biology
• Neuroscience

Background:

• Assisted Reproductive Technologies (ART) are used for 1-4% of births in developed nations.
• ART offspring show slightly increased neonatal malformation risks.
• Long-term ART follow-up suggests higher susceptibility to adult-onset multifactorial diseases like obesity, diabetes, and cardiovascular conditions.

Purpose of the Study:

• To review current knowledge on epigenetic alterations and neurological disorders in ART-conceived children.
• To assess the evidence linking ART, epigenetics, and neurological disease risk.
• To clarify the current understanding of long-term neurological health outcomes in ART offspring.

Main Methods:

• Literature review of epidemiological and experimental studies.
• Analysis of data on ART, epigenetic modifications, and neurological outcomes.
• Evaluation of the limitations of current research, including short follow-up periods.

Main Results:

• Little to no evidence currently supports an increased risk of neurological disorders in ART-conceived children.
• Most available reports are epidemiological, lacking experimental data on epigenetic modifications.
• The link between ART-induced epigenetic changes and long-term neurological effects remains unclear.

Conclusions:

• Current data do not indicate a significant increase in neurological disorder risk for ART children.
• Further research with longer follow-up and experimental evidence is needed to understand potential epigenetic impacts.
• The role of epigenetic alterations in ART-related long-term health effects, particularly neurological, requires more investigation.
