The sudden onset of transient blackness in one eye is a typical symptom of transient cerebral ischemia. Transient ischemic attack (TIA) is a sudden, transient, reversible neurological deficit due to focal cerebral ischemia caused by a transient lack of blood supply to the carotid or vertebrobasilar system. The onset of TIA lasts for a few minutes and usually recovers completely within 30 minutes, often leaving a slight neurological deficit for more than 2 hours, or CT and MRI show signs of cerebral ischemia. The onset of TIA is sudden, mostly under the circumstances of position change, excessive activity, sudden neck rotation or flexion and extension. There is no aura of onset, there are transient neurological localization signs, usually no impairment of consciousness, it lasts 5-20 minutes, it can be repeated, but it usually recovers completely within 24 hours without sequelae. People at high risk of transient ischemic attack or those who have had transient ischemic attack should pay attention to the following health care in daily life: 1. The significance and specific measures of dietary treatment should be understood. For example, patients with hyperlipidemia should have a low-fat diet, strictly prohibit the intake of animal oil, try to consume vegetable oil, preferably use foods containing less fat, avoid foods containing more fat such as fatty meat, duck, goose, etc., and prohibit fried and sticky foods. 2, exercise can reduce fat accumulation, lower blood sugar, improve cardiopulmonary function, accelerate blood circulation, promote metabolism, and improve the overall quality of the body. Exercise includes walking, jogging, tai chi, table tennis, swimming, rowing, ball games, etc.. Among them, throwing hands backwards walking and jogging are safe and easy, suitable for middle-aged and elderly people. Patients should master the intensity when exercising, step by step, 30-60min each time, once a day. 3. Enteric aspirin or Pansentine can be taken under the guidance of doctors to improve cerebral circulation. At the same time, drugs that act on vascular smooth muscle and increase brain flow, such as nimodipine and cerebrolysin, can also be used. Patients with diabetes should actively and effectively control blood sugar; patients with hyperlipidemia should use lipid-lowering drugs as early as possible in addition to adjusting the diet structure. 4, correct understanding of the disease to eliminate anxiety, tension and fear and other adverse emotions, so as to have a positive impact on the treatment effect. 5.After comprehensive treatment, most of the patient’s limb functions can be restored, but functional exercises of the limbs should be carried out regularly. Functional exercise of the upper limbs can be propped behind the hands, so that the hips as far forward as possible, and stretch the entire spine. Lower limb muscle strength exercise methods can walk up and down stairs, try to use the heel stirrups; supine legs can be in the air pedal bicycle, or hip elevation to do bridge activities. 6, maintain good living habits, work and rest on time, avoid overwork, maintain emotional stability, adjust the mentality, increase the interest of life; also pay attention to regular review of blood pressure, blood lipids, blood sugar, etc.
