Dystonia due to genetic defects is a movement disorder syndrome that is mainly caused by impaired coordination of contraction between the active and antagonist muscles or muscle over-contraction. It can be treated by oral medication, local injection of botulinum toxin A and surgery. 1. Oral medication: If the condition of dystonia is mild, it can be treated with medication such as carbamazepine tablets and levodopa tablets under the guidance of a doctor. 2. Local injection of botulinum toxin type A: Local injection of botulinum toxin type A can also be used to treat patients with localized dystonia. However, it is not suitable for treating patients with generalized dystonia. 3. Surgery: If dystonia is not effective with medication and the condition gradually worsens, it can be treated by surgery, such as deep brain electrical stimulation, microelectrode guided destruction surgery and so on. Patients with dystonia caused by genetic defects should go to the hospital in time, and the doctor will give the correct treatment according to the situation, do not blindly self-medication.
