Insights
Early hand preference in infants can indicate cerebral palsy (CP), a condition with diverse symptoms beyond spasticity. Prompt diagnosis is crucial for early intervention and improved outcomes in children with CP.
Area of Science:
- Neurology
- Pediatrics
- Developmental Pediatrics
Background:
- Cerebral palsy (CP) presents with diverse clinical manifestations, not limited to spasticity.
- Early hand preference is a potential, often overlooked, early sign of neurological conditions in infants.
- Traditional risk factors for CP are not universally present, complicating early identification.
Abstract:
We present a case of a 9-month-old boy with a history of unequal hand movements, right-hand preference on physical examination, and cortical dysplasia on brain magnetic resonance imaging who was eventually diagnosed with cerebral palsy (CP). Although spasticity involving one or more limbs is the most common neurologic sign of CP, there can be a variety of other presenting symptoms including early hand preference, hypotonia, and oral motor dysfunction. In addition, traditional risk factors of premature birth and intrapartum complications are not always present. Given the wide clinical spectrum of CP, it is important for primary care providers to maintain a high index of suspicion to ensure appropriate diagnosis and early access to interventions.
