NOTES – Neuro Developmental Outcomes of Twins from ESPRiT
The NOTES Study is a follow-up study to the ESPRiT Study, investigating Neurodevelopmental outcomes in twins at age 2. This project, funded through an award from the Crumlin Medical Research Foundation, provides a unique opportunity for a multi-centre, multi-disciplinary collaborative project. The successful outcome of the funding application was received in June 2010 and the NOTES study is now complete.
The NOTES Study (Neuro-Developmental Outcome for Twins of The ESPRIT Study) had 2 phases. Phase one which involved a standardised developmental questionnaire which parents fill out (ASQ-3, The Ages and Stages Questionnaire) is nearly complete with only a few remaining questionnaires to be sent out.
Phase 2 involved a detailed neuro-developmental assessment at 2-3 years of age (Bayley Scales Assessment of Infant and Toddler Development) on certain groups of twins:
1. Growth discordant twins (20% or more growth discordance)
2. High risk concordant twins (identified through the ASQ-3 questionnaire)
3. Control group (chosen randomly from the concordant group of twins after matching for gestation)
Overall, close to 500 Bayley Scales Assessment tests were performed.
Dissemination of Research
Preliminary analysis of our data began earlier this year with subsequent presentation of the NOTES finding at upcoming paediatric conferences. A number of major publications are currently in preparation.
