During childhood development, especially before 6 months of age, some babies may have symptoms similar to cerebral palsy such as muscle tension when crying, occasional head tilting back, hand clenching and holding standing pointed feet, but they can be identified accordingly if they are observed for abnormal posture, delayed disappearance of primitive reflexes, and gross motor development when the baby is in a good mood. Therefore, are there any symptoms that are often misunderstood as cerebral palsy? What is the difference between these misunderstood symptoms and the symptoms of cerebral palsy? In fact, the following diseases or symptoms are similar to cerebral palsy symptoms, but can still be differentiated. 1. Progressive spinal muscular atrophy, which starts in infancy and most of the symptoms appear after 3 to 6 months, and a few patients have abnormalities after birth, showing symmetrical weakness of the upper and lower limbs, progressive aggravation of muscle weakness, obvious muscle atrophy, and diminished or absent tendon reflexes. This disease is not combined with mental retardation, sensitive facial expressions, and flexible eye movements. Some children’s motor development is slightly behind that of their normal peers, especially premature children. However, they are not accompanied by abnormal muscle tone and postural reflexes, no abnormal movement patterns, and no other abnormal neurological reflexes. The symptoms of motor development lag can disappear within a short period of time as the child grows older and focuses on motor training. 3. Children with congenital myasthenia gravis have obvious hypotonia, muscle weakness, and low or absent deep tendon reflexes after birth. It is often easily complicated by respiratory infections. This disease is sometimes misdiagnosed as hypotonia cerebral palsy, but the latter tendon reflexes can usually be elicited. 4. Mental retardation often has backward motor development, uncoordinated movements, abnormal primitive reflexes, vojta postural reflexes, corrective responses and balance responses, and is easily misdiagnosed as cerebral palsy in early infancy, but its symptoms of mental retardation are more prominent, with basically normal muscle tone and no postural abnormalities.
