1, epilepsy: certain types of epilepsy such as temporal lobe epilepsy can appear smacking and other movements; myoclonic epilepsy has a localized muscle jerks seizures, but epilepsy tends to be episodic, while tic disorders twitching phenomenon is more frequent. Epileptic seizures are generally not controlled by the will, while tics can be controlled by the will for brief periods of time. Epilepsy EEG has special changes, there can be epileptic waves, etc., while tic disorder EEG is generally normal. 2, chorea: this is the rheumatic lesions involved in the extrapyramidal system caused by involuntary unconscious movements of the limbs and face, in addition, there can be changes in body temperature, blood sedimentation, C-reactive protein and anti-“O”, etc., before the onset of streptococcal infection, but tic disorders do not have these symptoms, if there is no symptom of co-infection, the above test indicators are normal. 3. Hepatomegaly: This disease is an autosomal recessive hereditary, congenital copper metabolism disorder, with liver damage, extrapyramidal symptoms and corneal pigment ring as the main manifestations. There are many types of Tourette’s syndrome, among which Tourette’s syndrome is mainly characterized by involuntary movements of the head and face such as squeezing eyebrows, making eyes, twisting the nose, smacking the lips, swinging the head, twisting the neck, etc., or abnormal movements of the limbs such as twisting and dancing. It is necessary to check the liver and kidney function, copper blue protein, urine routine, and cranial magnetic resonance imaging (MRI) to assist in the diagnosis and understanding of the condition. Pediatric Tourette Syndrome symptoms are similar to those of the above disorders, so relevant tests are often needed to rule out these disorders and clarify whether it is Tourette Syndrome.
