Dizziness and insomnia at night can be caused by anxiety disorders or depression. Both of these disorders are a type of mental disorder. Patients can present with somatic signs and symptoms as well as psychological symptoms. Patients with somatic symptoms may present with dizziness, head swelling, nausea and vomiting, and may experience precordial discomfort, palpitations, chest tightness, shortness of breath, and may also experience sleep disturbances. Anxiety disorders are patients who generally present with difficulty falling asleep and may also have nightmares during sleep that affect sleep quality. Patients with depression mainly present with early awakening during sleep and may also have dreams during sleep. In the case of anxiety disorders, oral treatment with tandospirone, buspirone or lorazepam is usually given. If depression is considered, the main treatment is oral citalopram, and mirtazapine and Dexedrine can also be used.
