Cerebral palsy and cerebral atrophy are two different concepts. Cerebral palsy is a disease, usually a disorder of motor coordination caused by central injury, manifested by movement disorders, backwardness in development, postural abnormalities and organic abnormalities, often accompanied by sensory abnormalities, perceptual abnormalities, and even epilepsy and other symptoms. Cerebral atrophy is one of the pathological changes, and the brain volume of the patient is less than that of a normal person, and the clinical manifestations are more frequent. Therefore, in case of brain atrophy, it is necessary to determine whether the brain volume is reduced with the help of imaging tests, and if symptoms of brain atrophy appear, timely treatment is needed.
