Patient: My son is 12 years old and has normal intelligence. In the last few years, I found that he often blinks during school classes and on the Internet, or his eyes suddenly slant, and sometimes the corners of his mouth slant and all sorts of sneaky movements. I’ve seen an ophthalmologist and there’s nothing wrong with it, is there something wrong with the brain waves? I’d like to ask Dr. Ken to identify whether there is a problem with the brain waves or not. Because my usual observation is not like a habit. Jin Lingjing, Department of Neurology, Shanghai Tongji Hospital: Hello! You are asking if there is something wrong with the “brain waves”, which can only be determined after an EEG examination; I guess you are asking if this is consistent with epilepsy. From what you have described, it is different from the common manifestations of epilepsy and does not appear to be due to eye disease. We suggest you to find out if your child can concentrate in class. Are there any eye-rolling, blinking, or frequent sounds in the throat? Are there any psychological or behavioral abnormalities or learning difficulties? If so, the child may have Tourette’s syndrome and should be seen in the hospital for formal evaluation and treatment. If there are no such problems, it is recommended to control the time spent on the Internet and watching TV and to increase outdoor activities appropriately.
