Abstract

Infant hypotonia is a nonspecific sign on physical examination that may appear in multiple diseases. Early detection from primary care through health reviews is necessary. An adequate clinical history with an age-adapted neurological examination to distinguish between central and peripheral hypotonia, will be key in the initial diagnostic approach. We present the case of a one-month-old infant with hypotonia. The diagnosis of spinal muscular atrophy is confirmed, a rare entity whose prognosis has improved due to the discovery of new therapeutic strategies.
