Children with cerebral palsy do not have defined facial features, but can present with facial muscle spasms, a single expression, a blank stare, difficulty in closing the mouth, and eye movement disorders (e.g., outward and upward strabismus). Cerebral palsy is a non-progressive injury to the brain that occurs during the early development of a fetus or infant due to a variety of causes. It mainly manifests as central motor and postural developmental disorders, and is accompanied by symptoms such as perceptual, sensory, and cognitive disorders, language disorders, and behavioral abnormalities. Cerebral palsy is one of the major diseases that cause motor abnormalities in children. The main clinical features of cerebral palsy are motor development disorders and abnormal muscle tone. In the face, there may be stiffness of the facial muscles, dullness of the eyes, difficulty in closing the mouth with salivation (drooling), and so on. If you suspect that your child has cerebral palsy or brain injury, you should consult a doctor in time to complete the relevant examinations and cooperate with the doctor for active treatment.
