If a patient feels dizzy and depressed frequently, there are many causes of this symptom and patients are advised to go to the hospital for early examination. Common ones, such as anemia and other blood system disorders, can cause dizziness and mental discomfort in patients. In addition, diseases such as cardiac arrhythmia, coronary artery insufficiency, coronary heart disease, and cardiac system diseases can also cause dizziness and dysphoria. Poor rest, insomnia, and emotional stress can cause cerebral vascular spasm, resulting in insufficient blood supply to the vertebral basilar artery, which can lead to dizziness and mental discomfort. If a patient has cervical spondylosis, which compresses the vertebral artery, he or she can also suffer from dizziness and mental discomfort due to chronic insufficiency of blood supply to the cerebral arteries. Patients are advised to go to the hospital for blood tests and cardiovascular and cerebrovascular examinations as early as possible to make a clear diagnosis and then undergo treatment.
