Cerebral palsy is a non-progressive motor dysfunction that occurs before birth, or at birth, or after birth due to infection, and in severe cases is accompanied by mental retardation, convulsions, auditory and visual impairment, and behavioral abnormalities. Early detection and treatment can be extremely helpful for the future self-care of cerebral palsy patients. How to detect early? In the first month after birth: If the infant has stiffness of both lower limbs when lying supine, difficulty in passive flexion and abduction, head and neck extension, shoulder and arm retraction, and arm abduction …… these are all hints for parents to pay attention to cerebral palsy. Most infants with cerebral palsy do not show signs of spasticity in the neonatal period, but rather varying degrees of hypotonia. After 3 months of age: If the child makes a fist with both hands, when the thumb is clenched in the palm, one hand can be opened while the other hand is clenched, and also shows difficulty in raising the head when in prone position, these can prompt attention to the presence of cerebral palsy. 6 months of age or less is the most difficult period to recognize cerebral palsy, and if there are signs, you should see a specialist immediately for examination. After 7 or 8 months of age: Not being able to crawl or sit is the most common symptom in children with cerebral palsy. At 1 year of age: Children who often use one hand to reach for things and show asymmetrical voluntary movements.
