For children with brain injury, if they are detected, diagnosed and treated early, they can often achieve more desirable results and can minimize the sequelae caused by brain injury. So how can a mother determine whether her child has cerebral palsy through her child’s performance, so that she can seek medical attention early? The following are some of the common early symptoms of brain injury: 1. During the newborn period (within one month), children do not suck or suck weakly or refuse to breastfeed; 2; 5. When the child reaches 1 to 3 months of age, he or she will also have a clenched fist, inward thumb, inattention to people, indifferent facial expression, and inability to raise the head in the prone position; 6. At 4 to 5 months of age, the eyes are inflexible, will not follow objects, will not pay attention to people, has a dull expression, will not roll over, raises the head less than 90° in the prone position, does not actively reach out to grasp objects or only uses one hand to grasp objects; 7. After 6 months of age, abnormal posture is obvious, such as hands still clenched, toes on the ground, double lower limbs crossed, etc., accompanied by obvious motor development delay.
