Frequent head shaking is considered to be caused by pediatric Tourette’s syndrome, idiopathic tremor, epilepsy and other diseases. 1. Pediatric Tourette Syndrome: This disease is a kind of mental disorder that occurs in children and adolescents, the specific cause of which is still unclear, and is clinically considered to be related to genetic factors, psychological factors and other influences. Before the onset of the disease, patients often have burning sensation in the eyes, sore throat and other uncomfortable symptoms. With the onset of the disease, patients will have repeated, involuntary, purposeless muscle twitching, such as blinking, nodding, shaking the head, pouting and so on, and some patients may shake their heads frequently as the main clinical symptom. 2. Idiopathic tremor: this disease is an autosomal dominant disease, patients often have involuntary trembling of the hands, tongue or head and neck at the early stage of the disease, which leads to frequent shaking of the head. At the same time, with the development of the patient’s condition, the trembling symptoms can also gradually affect the voice, trunk, legs and other parts of the body. 3. Epilepsy: This is a common chronic brain disease, mainly due to the presence of cerebral cortical development disorders, head trauma, or brain tumors, meningitis and other conditions. Different patients have different clinical symptoms after the onset of the disease, some patients may have localized muscle spasm attacks, and some patients may have automatism attacks such as repeated chewing, repeated nodding or shaking of the head, all of which may lead to frequent shaking of the head. Recently, patients with frequent head shaking are advised to seek medical examination as soon as possible to clarify the cause of the disease and then actively treat it.
