Like many of the neonatal reflexes (e.g., grasping,
rooting, placing, tonic neck reflexes), these motor patterns
disappear as neuron connectivity and myelination
matures. Examples include the minimal chorea
of infants, the mild action dystonia commonly seen
in toddlers, and the overflow movements that are
commonly seen in young children. Other transient
or developmental movement disorders may be manifestations
of abnormal neural function, but do not
correlate with serious underlying pathology. These
are typically associated with complete resolution of
the abnormal movements and ultimately normal
development
