How do congenital muscular dystrophies typically present compared with later-onset muscular dystrophies?

Explanation:
Congenital muscular dystrophies typically present at birth or in early infancy with generalized hypotonia (a floppy baby) and often with brain involvement, such as structural brain abnormalities or seizures. This early onset with CNS involvement is what distinguishes CMD from muscular dystrophies that begin later in childhood or adolescence, which usually show proximal muscle weakness and a different progression pattern. While cardiomyopathy can occur in some forms, it isn’t the defining feature of CMD, and isolated facial weakness that appears later is not typical.
