Not long ago, a friend from out of town called me to inquire about the condition of one of his relative’s children, saying, “The child is more than 10 years old and has been experiencing episodes of numbness and weakness in his limbs recently. He had been seen many times at the local hospital, but the conclusions varied, with most believing that he was not ill, and some even believing that he was suffering from a psychological disorder. As a specialist in neurology, I was naturally particularly concerned about whether the affected limb was unilateral or bilateral, and the answer was unclear. I then spoke directly with the child’s mother on the phone, who described the onset of the disease as being bilateral, and said that the child had trouble standing for a while, with frequent episodes at school. She also suspected that the child was not willing to go to school and was pretending to be sick on purpose. Because of the lack of first-hand medical information, I was at a loss as to what the most appropriate course of action would be to continue further examination. At this point I heard her child on the other end of the phone arguing with her for some reason, and I hurriedly said, “Give the child the phone, I’ll talk to him.” On the phone, the child said, “My arm is not numb at all, it just doesn’t work when I stand up.” I immediately had a flash of insight and asked, “Is it when you get up from your seat or when you first start running?” The answer was yes. Over the phone I asked him to do a high leg raise in place, and the symptoms were induced within a few minutes. At this point, even without any tests, the diagnosis was basically clear: this is a kind of “kinesigenic episodic chorea”, which belongs to a kind of ion channel disease causing episodic dystonia, which can be triggered by movement, and the patient is normal during the interictal period. Treatment is very simple, and oral carbamazepine in small doses is very effective. In clinical practice, there are many doctors who do not like to see children very much, believing that they cannot easily communicate and describe the condition. However, experienced pediatricians know that pediatric patients generally give the most honest account of their condition, without the subjective analysis and misinformation that adults do. Therefore, we should allow a period of time for children, especially those who are rebellious, to talk and communicate, and listen to their voices so that we can accurately grasp their condition. As a parent, you should also consider when bringing your child to the clinic: How much do you talk to your child? Is your child willing to tell you about his or her condition? Why is the child uncooperative or impatient with your concern? Parents who are used to taking care of everything for their children should reflect on the gains and losses.
