The principle of transcranial magnetic therapy is based on the principle of electromagnetic stimulation, which can improve the excitability of the brain and can regulate the release of neurotransmitters. Transcranial magnetic stimulation therapy is a non-invasive neurostimulation technique, which is commonly used clinically for the treatment of anxiety disorders, bi-directional affective disorders, depression, sleep disorders, and as an adjunctive treatment to medication, it can significantly improve mental symptoms. High-frequency, high-intensity transcranial magnetic stimulation produces a sum of excitatory postsynaptic potentials, leading to abnormal nerve excitation at the stimulation site. Low-frequency stimulation has the opposite effect, treating the disease by bi-directionally regulating the balance between excitatory and inhibitory functions of the brain. For different patients with different brain function conditions, different intensity, frequency, stimulation site, coil direction should be used to adjust in order to achieve good therapeutic effect. Common adverse effects of transcranial magnetic therapy include sudden hearing loss and seizures, as well as headache and dizziness. Transcranial magnetic therapy should be performed according to medical advice and requires specialized personnel to perform the therapeutic operation.
