What is the reason for a 14-year-old boy's cold and sweaty feet after sleeping?

Patient's question:

14-year-old boy, after sleeping, his feet are cold and sweaty, what's going on? How to regulate it? Thank you. Medical history and treatment effects: Has had childhood cerebral palsy since childhood

Doctor's answer:

This symptom cannot be ruled out as ataxic cerebral palsy, characterized primarily by lesions in the pyramidal system and cerebellum, with involuntary, rhythmic oscillation of a part of the body in a single plane. The main manifestations of ataxic cerebral palsy are static tremors, coarse and rhythmic, temporarily suppressed during conscious movement, commonly seen in the upper limbs, sometimes, worsening during movement, with nystagmus. Pure ataxic cerebral palsy is rare and often coexists with other types.
