I have been on a two week research stay with Dr. Rebecca Bromley at the University of Manchester. Dr. Bromley is a neuropsychologist who works mainly with child neurodevelopment after prenatal exposure to antiepileptic medications, and she has made important contributions to this field. During my stay I have had the opportunity observe assessments of neurodevelopment in toddlers using both observation based tests and interview/survey type tests. This has improved my understanding of the strengths and weaknesses of different types of tests, which is of great value for my current work (a systematic review with focus on validity of outcome measures in studies on neurodevelopmental outcomes in children prenatally exposed to psychoactive medications). From my conversations with Dr. Bromley, and from the literature I read in Manchester on her recommendation, I have also become more aware of the complexity of neurodevelopment and hence the importance of interdisciplinary collaboration in our research projects on this outcome. I will continue to collaborate with Dr. Bromley for my systematic review, and I hope that we may welcome her in Oslo before long.
