Overview
This research explores General Movements (GMs) in a reference population. Abnormal general movements in babies are predictive of autism spectrum disorders or neurodevelopmental deficits.
General movements have received little attention in the context of foetuses, which is why developing a reading grid to analyse general movements in foetuses could be a valuable tool for facilitating early diagnosis and prompt treatment of at-risk babies.
Description
The identification of General Movements (GMs) in utero is not common practice among ultrasound technicians. However, it has been shown that poor or abnormal general movements in premature or full-term infants is a marker of the risk of later developing autism spectrum disorders or neurodevelopmental disorders. Prenatal screening currently focuses on detecting morphological malformations rather than the quality of general movements. Movement stimulates brain development through epigenetic action, and ultrasound enables this development to be monitored during pregnancy. General movements have been little studied in the foetus, and the introduction of a reading grid enabling general movements to be identified in utero could provide a new tool for ultrasound scanners in identifying risk situations at perinatal and/or postnatal level.
The investigators hypothesise that analysing ultrasound recordings as part of this research could lead to the creation of a grid to help identify general movements in utero. This would be a first step towards introducing a new tool for ultrasound technicians to use in the early detection of autism spectrum disorders or neurodevelopmental deficits.
