Patients with mild depression can choose inpatient treatment or outpatient treatment. The main decision depends on the communication between the patient, their family, and medical professionals. Patients with mild depression have relatively mild depressive symptoms, so psychological therapy is primarily used, with pharmacotherapy and physical therapy serving as supplementary treatments. Psychological therapy mainly employs cognitive-behavioral therapy to improve the patient’s unreasonable beliefs and alleviate emotional stress. This includes identifying automatic thoughts, recognizing the irrationality of cognition, and employing reality testing, ultimately aiming to improve the patient's symptoms. Pharmacological treatment primarily uses serotonin reuptake inhibitors, and patients can adhere to a regular medication schedule at home during outpatient treatment periods. Physical therapy consists mainly of transcranial magnetic stimulation, which can be administered either as an outpatient or inpatient treatment. The final treatment choice should involve comprehensive communication with the patient's family and physicians to make an informed decision.
