What tests are needed for pediatric attention deficit hyperactivity disorder (ADHD)?

The examination for childhood hyperactivity disorder mainly includes the following aspects: 1. Electroencephalogram (EEG) test: This is a common method for evaluating hyperactivity disorder. A relatively high proportion of children with hyperactivity show abnormal EEG results, which helps in diagnosis. 2. Finger-to-target test: The child is asked to make one hand into a fist and use the thumb of the other hand to sequentially touch the tips of the remaining fingers. The coordination and speed of movement are observed; lack of smoothness or inflexibility may indicate a positive result. 3. Finger-to-nose test: The child is instructed to use the index finger of each hand alternately to touch the tip of the nose, performing the task five times with eyes open and five times with eyes closed. Coordination and speed are evaluated. Children with hyperactivity disorder often exhibit excessive force and clumsiness in movements, particularly when their eyes are closed. 4. Hand-flipping test: The child places both hands flat on a table, palms down, and repeatedly flips both hands over as quickly as possible. The amplitude of elbow movements and the posture of hand flipping are observed. Abnormal swinging or lack of coordination may indicate a positive result.
