Cerebral palsy within three months of the seven-step self-test” this statement lacks scientific basis, cerebral palsy need to be based on clinical symptoms, professional examination and medical history and other comprehensive analysis to confirm the diagnosis. 1. Clinical symptoms: One of the requirements for diagnosing cerebral palsy is clinical symptoms. Children with cerebral palsy show abnormal motor and postural development, such as inability to roll over, crawl, walk and grasp; children may also show abnormal muscle tone, some of them are stiff, some of them have floppy limbs, which is different from normal; and there are also abnormal reflexes, such as sucking reflex. 2. Specialized examination: Physicians may perform imaging tests, such as cranial MRI, cranial ultrasonography, and cranial CT, which can help to diagnose cerebral palsy and locate the site of the lesion, as well as electroencephalograms and electromyograms, which can help to determine the developmental status of the child. 3. Medical history: The physician should also ask the family about the child’s medical history. For example, whether the child had intrauterine infection before birth, whether the pregnant woman had eclampsia, placental abruption, placenta previa, etc.; whether the child was born preterm, had an abnormal delivery, had asphyxia, or had a difficult delivery; and whether there is a family history of cerebral palsy in the child. The so-called “seven-step self-test” at home cannot diagnose cerebral palsy, and if you suspect cerebral palsy, you should go to the hospital in time for professional diagnosis and treatment.
