«Our partnership with families who have a
child with Down syndrome and our
investment in a comprehensive clinical data and biorepository will continue to provide resources to study not only heart defects, but also other Down - syndrome associated medical
conditions such as cognitive function, leukemia, and dementia,» says co-author Stephanie Sherman, PhD, professor
of human genetics at Emory University School
of Medicine.
Early development consists
of critical periods during which
children are vulnerable to exposures.34 Delays in
children's development occur cumulatively and start as early as conception, which supports arguments for early
investments.35 The impact
of different nutrients on
children's development depends on timing, dose and duration
of deficiencies.8, 36 Parenting practices and home environments also influence
child development and may either accentuate or attenuate the effects
of poverty, which directly affects
child outcomes.37 Thus, potential intervention effects can vary according to timing, exposures and environmental
conditions.38 For these reasons, it is important to consider trajectories
of child development across a spectrum
of ages, not just any one age.39
