CHILDREN'S ENVIRONMENTAL HEALTH

Impact of early life exposure to fluoride on children's learning and behavioural outcomes

    • ​We are interested in understanding neurobehavioural outcomes related to early life fluoride exposure, mechanisms underlying neurotoxic effects, exposure measurement, and much more
    • ​We are currently conducting studies examining both prenatal and postnatal exposure to fluoride on child behavioural outcome using a New Hampshire birth cohort (NHBCS), different Canadian population-based cohorts (e.g. MIREC, CHMS) as well as a large birth cohort from Mexico City (ELEMENT)
    • See here for information about our current Canadian research on fluoride neurotoxicity and here for information about our current research in the US

  • The relationship between fluoride exposure in pregnancy and thyroid function

  • Fluoride in tooth dentin

CLINAL NEUROPSYCHOLOGY

  • Clinical and MRI correlates of cognitive functioning in children and adolescents with multiple sclerosis (MS) and acquired demyelinating disorders

  • Longitudinal modeling of cognitive changes associated with pediatric-onset multiple sclerosis and acquired demyelinating syndrome
