If a patient feels a little dizzy at times, the following points should be considered: First, neurological lesions should be taken into account, for example, the most common factor is the alteration of cerebral ischemia, such as transient cerebrovascular insufficiency of blood supply, acute cerebral arterial insufficiency of blood supply, or cerebral infarction, cerebral embolism, and other conditions can lead to dizziness. Second, if the patient has substantial brain lesions, such as intracranial tumors, intracranial infections, and occupancies, this can also lead to this condition. Third, trauma to the brain or dysfunction of the vegetative nerves due to various factors will also often cause dizziness spontaneously. For cardiovascular diseases, often in hypertension, sinus bradycardia, heart failure, and atherosclerosis, dizziness will be felt secondary. Fourth, if the patient has a blood disorder, or anemia, or high blood viscosity, it will also lead to frequent dizziness of self-consciousness.
