Patient's question:
What are the characteristics of the onset of infantile spasms?Doctor's answer:
The clinical manifestations mainly have three forms: (1) bowing-like spasms: characterized by sudden recurrent brief generalized muscle spasms, where the neck, torso, and legs bend inward or outward, and both arms are quickly extended forward and outward in an embrace-like posture; (2) nodding-like spasms: characterized by recurrent nodding; (3) lightning-like spasms: with very short duration, making them difficult to notice unless one pays attention.
