Symptoms of cerebral palsy in three-month-old infants mainly include backward motor development and postural abnormalities, which may also be accompanied by electroencephalogram (EEG) abnormalities. Cerebral palsy in three-month-old infants will cause the neurological, perceptual, motor, language and psychological development to lag behind that of normal children, and the children often show symptoms such as frequent convulsions, inability to hold up their heads, wobbly hands and feet, and increased or decreased muscle tone. Generally speaking, the symptoms of cerebral palsy in three-month-old infants are often atypical. They may show backwardness in intellectual and motor development, inability to hold up the head, abnormal muscle tone, etc. In severe cases, frequent convulsions may occur, but due to the young age of babies, the brain development is not perfect, and it is usually difficult to identify tiny convulsive episodes. EEG and other related tests can be performed to help diagnose the disease. Babies with cerebral palsy can be helped to improve their developmental backwardness through early functional training, such as physical exercise, skill training, language training, etc. Antiepileptic medication can be given under the guidance of the doctor if seizures are frequent. If your baby is diagnosed with cerebral palsy, it is recommended that he or she receive targeted treatment under a doctor’s supervision.
