Which department should a person visit if they have no feeling of sleepiness?

When a person has difficulty falling asleep, they may visit departments such as neurology, internal medicine, or psychiatry. The details are as follows:

1. Neurology

Neurologists can perform neurological examinations and assessments to determine whether any neurological conditions—such as insomnia or sleep apnea syndrome—are present. If necessary, neurologists may also prescribe appropriate medication treatments.

2. Internal Medicine

Internal medicine physicians can evaluate the patient's overall physical condition and check for underlying medical conditions or metabolic abnormalities, such as diabetes or hyperthyroidism, which may contribute to chronic insomnia.

3. Psychiatry

If chronic insomnia is caused by psychological or mental health issues, patients may need further evaluation and treatment in the psychiatric department. Psychiatrists can help diagnose and treat mental disorders such as anxiety and depression, which may also lead to persistent sleep difficulties.

In addition to the above departments, patients may also consult a sleep medicine specialty clinic. Individuals experiencing sleep disorders are advised to seek timely medical attention at a hospital.
