Laboratory tests: For example, for unexplained cerebral palsy, the coagulation mechanism can be examined to check whether the patient has coagulation disorders. 4. Imaging tests: Commonly, such as cranial MRI, CT examination helps to determine whether there is any structural abnormality in the patient’s cranium, in order to help make a diagnosis. 5. Other tests: Commonly, such as electroencephalogram, brain auditory evoked potentials, genetic metabolic disease examination, and so on. These tests help the doctor to make further diagnosis.
