Iron deficiency (ID) anemia is associated with poor neurocognitive development in infants and children. Depending on the stage of development at the time of deficiency, these adverse effects may be reversible. Recent investigations using sensitive measurements have confirmed that the deposition of iron in the brain varies according to brain region and age, and that dopamine-dependent behaviors are among the core deficits in ID. Dr John Beard (1947–2009) has been one of the leading scientists and pioneers in the area of iron and child development. His legacy to this area of science will grow through the continuation of his work by his co-workers and colleagues.
