Cerebral palsy, or cerebral palsy, is the leading cause of pediatric disability. In recent years, its incidence has been increasing year by year. The latest domestic statistics show that the prevalence rate of pediatric cerebral palsy is 1.92‰, which seriously affects the quality of our population. If cerebral palsy is correctly understood, diagnosed early and treated actively, most of the cases can obtain a more satisfactory result. However, delayed diagnosis and loss of early treatment will increase the incidence of disability and worsen the degree. Unfortunately, many cases of cerebral palsy are misdiagnosed as rickets due to calcium deficiency, and as a result, the child loses the best opportunity for early treatment. Therefore, it is necessary to identify cerebral palsy and rickets at an early stage. Cerebral palsy refers to “central motor deficits and postural abnormalities caused by non-progressive brain injury from before birth to one month after birth.” In other words, the main manifestation of children with cerebral palsy is movement disorders and postural abnormalities. The early manifestation of this motor disorder is delayed motor development, which is often referred to as “softness” by parents, such as delayed head lifting, rolling over, holding objects, sitting and standing. The most common postural abnormalities are head tilting back, eye strabismus, internal rotation of the upper limbs, hand back, and inward tiptoeing of the lower limbs. When asked about the medical history, most children have mental retardation due to the mother’s history of obstructed labor, hypoxia and asphyxia before and after birth, and abnormal brain CT examinations. Many parents think that children with calcium deficiency are “soft”, so they blindly give calcium supplements to early cerebral palsy children and delay treatment. In fact, calcium deficiency in children is a chronic nutritional disease caused by abnormal calcium and phosphorus metabolism due to vitamin D deficiency, which is fundamentally different from cerebral palsy. The main manifestations of rickets in infancy are crying, easy to be frightened, excessive sweating, etc. In heavy cases, there may be a delay in the development of movement, but all other aspects are normal, there is absolutely no abnormal posture or mental retardation, and the mother has no history of difficult delivery or cerebral hypoxia before and after the birth of the child. The key to the treatment of cerebral palsy is “early”. Within half a year of age is the fastest period of brain cell development and maturation of brain function, so the child should be given appropriate medication to promote brain metabolism and improve brain circulation, as well as oxygen absorption. For delayed movement and abnormal posture, special rehabilitation treatment, including massage, physical therapy, acupuncture, etc., is needed. Children with rickets, on the other hand, only need more sunlight and vitamin D and calcium supplements.
