Disorientation is also a kind of disorder of consciousness, a sudden disorientation, which means a sudden onset of consciousness. It is most common in middle-aged and elderly people, and the first thing to consider is acute cerebrovascular disease, where the patient may suddenly appear to be in a trance, babbling, and not responding to calls. At this time, the patient should be rushed to the hospital for relevant cranial CT examinations to exclude cerebrovascular disease. There are other reasons why patients with hypoglycemia may also experience blurred consciousness, because some patients with diabetes, who have been taking oral hypoglycemic drugs or insulin therapy for a long time, may experience hypoglycemia and may suddenly appear in a trance. If you have that kind of blood glucose meter at home, you can check your blood sugar urgently. There are also causes, such as infection, pulmonary encephalopathy, hepatic encephalopathy, and drug intoxication that may cause sudden onset of consciousness. So once the patient has similar symptoms, it is recommended to send to the hospital for treatment as early as possible.
