I can't sleep. What's going on in the hospital?

What department to go to the hospital for sleeplessness? Make clear the purpose of the patient's visit to the hospital and the condition of the underlying disease. If sleeplessness is to find out the cause, it is necessary to improve the nocturnal polysomnography, cranial CT or MRI examination, etc., and it is recommended that the patient hang the neurology department number. If sleeplessness is caused by anxiety and depression, the effect of sedative and hypnotic drugs used in the past is relatively poor. It is suggested that the patient go to the mental health center for treatment and take anti-anxiety and anti-depression drugs under the guidance of doctors. Sleeplessness is caused by malignant tumors of certain systemic diseases. For example, patients with liver cancer who cannot sleep need to hang up the digestive medicine department and adjust the corresponding liver cancer drugs under the guidance of the doctor. At the same time, they can go to the neurology department for treatment for sleeplessness and adjust the sedative and sleeping drugs under the guidance of the doctor.
