The head shakes involuntarily, then the first thing to look for the cause, generally seen clinically in patients with Parkinson’s syndrome or primary tremor, can appear to have voluntary head shaking. Parkinson’s syndrome is clinically common with Parkinson’s disease. The patient first appears to have tremors of the limbs, mainly resting tremors, and as the disease progresses, the patient can develop whole-body tremors and involuntary head shaking, and the patient can be given oral medications such as Medroba or Morpholog. If necessary, the patient can consult a neurologist for oral treatment under the guidance of a physician. For idiopathic tremor clinically, it is mostly seen in elderly people over 40 years old. At present, if the tremor has a significant impact on the patient’s quality of life, drugs such as oral propranolol or clonazepam can be considered for control. If the impact on life is not significant, oral medications can be temporarily disregarded. If you are a young person and your head is shaking involuntarily, it is recommended that you check your head MRI to rule out intracranial occupancy as a cause of irritation and, if necessary, check your nail function to see if it is caused by hyperthyroidism, a metabolic condition.
