Question
What are the clinical symptoms of neonatal spasm syndrome?
Answer
The clinical manifestations of neonatal spasm syndrome mainly come in three forms: (1) bending spasm, characterized by sudden, short-lived whole-body muscle spasms, with the neck, trunk, and legs flexed and adducted or abducted, with hands reaching forward and outward in a hugging posture; (2) nodding spasm, with repetitive nodding episodes; (3) lightning-like spasm, which lasts for a very short duration and is difficult to detect unless noticed carefully.
