Identification of the cause is crucial for determining the prognosis and possible early interventional options. Since the etiology is heterogeneous, a systematic approach to infants with hypotonia is necessary. In this chapter, we aim to give a general perspective of diseases that cause hypotonia and establish a diagnostic algorithm for infants who present with hypotonia.
