Children with syndromic, congenital vestibular disorders (CVDs) form a sac-like inner ear with missing or truncated semicircular canals and experience delayed motor development with lifelong challenges to maintain posture and balance. How the abnormal inner ear affects downstream central vestibular neural circuitry has not been investigated....
No actionable clinical change; this is a basic-science animal study, but it deepens understanding of why congenital vestibular disorders cause lasting motor development problems.
Identifying the neurodevelopmental consequences of malformed vestibular structures could inform future therapeutic targets for children with congenital balance disorders.
