Idiopathic tremor is an autosomal dominant disorder, the most common extrapyramidal disorder, and the most common tremor disorder, with a family history in approximately 60% of patients. Idiopathic tremor is a single-symptom disorder, and postural tremor is the only clinical manifestation of the disease. Postural tremor is a tremor that is triggered when the limb is maintained in a certain position, and it disappears naturally when the limb is completely relaxed. Tremor in this disease is commonly seen in the hands, followed by tremor in the head, and in very few patients, tremor in the lower extremities. The tremor of this disease is aggravated by concentration, mental tension, fatigue, and hunger. In most cases, it disappears temporarily after drinking alcohol and worsens the next day, which is also a characteristic of idiopathic tremor.
