Most children with cerebral palsy are not purely spastic or purely tardive, but have more or less a mixture of factors. Spasticity and tonicity are present in almost all cases, and most children with birth asphyxia present with a combination of spasticity and tardive dyskinesia. Most of them are a mixture of spasticity and tardive dyskinesia, but there are also tardive dyskinesia with dystonia and an appeal between the three. In the mixed type of spasticity with tardive dyskinesia, it is worth noting that tardive dyskinesia is evident in the upper extremities and spasticity is evident in the lower extremities. In some cases, tardive dyskinesia is evident in one position and spasticity is evident in another. This is often the case when asphyxia and jaundice overlap. These children appear to be in a spastic posture in the supine position, but from the sitting position to standing up, they show a pronounced facial distortion, open mouth, involuntary bending of both upper limbs, especially the two hands, and spread fingers. Children with severe cerebral palsy are generally unresponsive to postural changes, and those who are more tense tend to adopt spastic-like postures when they are quiet, while elements of tardive dyskinesia become apparent as soon as they make casual movements. In mixed cerebral palsy, severe cases are more common and are often associated with mental retardation and epilepsy. For intelligence, the more elements of tardive dyskinesia, the better the intelligence. The diagnosis is usually made clinically according to the diagnostic principle of dominant impairment, and a true diagnosis of mixed type is rare.
