What this trial studies

This single-center observational study will examine neurological status, motor development, and sensory processing in term infants aged 6–18 months who were diagnosed with primary congenital hypothyroidism and treated from the newborn period. Participants will undergo standardized neurological and developmental examinations and structured measures of sensory processing, with results compared to age-based norms. The work is motivated by early synaptogenesis and a gap in the literature on sensory processing in this age range, complementing prior work on cognition and motor outcomes. Findings are expected to inform timelines for early follow-up and possible interventions.

Who should consider this trial

Good fit: Term-born infants aged 6–18 months with primary congenital hypothyroidism who have been treated since the newborn period and are currently on therapy are ideal candidates.

Not a fit: Preterm infants, those with secondary hypothyroidism, congenital infections, proven genetic alterations, other metabolic/neurological/genetic diseases, or whose parents do not consent are excluded and would not benefit from participation.

Why it matters

Potential benefit: If successful, the results could help clinicians detect early sensory or motor differences and guide targeted follow-up and early intervention for infants with congenital hypothyroidism.

How similar studies have performed: Previous research shows early thyroxine treatment generally normalizes IQ but mild motor and attention problems can persist, while sensory processing in early infancy remains largely unstudied, making this a relatively novel area.
