How should childhood hyperactivity disorder be evaluated?

The examination for childhood hyperactivity disorder mainly includes the following: 1. Electroencephalogram (EEG) testing: By recording spontaneous brain electrical activity, abnormalities are found in approximately 50% of children with hyperactivity disorder, primarily表现为 moderate abnormalities and epileptiform activity. 2. Behavioral assessment: Methods such as the finger-tapping test and finger-to-nose test are used. In the finger-tapping test, the child's ability to quickly and flexibly touch the tip of each finger with the thumb is observed. In the finger-to-nose test, coordination and speed when the child uses the index fingers of both hands to alternately touch the tip of the nose are evaluated; children with hyperactivity disorder often appear clumsy and make frequent errors. 3. Hand-flipping test: Observe the amplitude of elbow movement, hand posture during flipping, and whether both hands can be brought together. Excessive elbow swinging and clumsy hand-flipping movements may indicate a positive result. 4. Neurophysiological testing: Includes EEG and other tests to directly assess the overall physiological function of the nervous system.
