Stroke (stroke) has become the number one cause of death in China. If a stroke causes extensive lesions or large blood vessel occlusion, the condition is often more dangerous and the mortality rate is high. ”One person has a stroke, the whole family suffers”, which is a real epitome of the huge blow to a family caused by a stroke. Because of its suddenness and severity, stroke places a heavy burden on individuals, families and even society. Therefore, the prevention of stroke is more critical than the treatment. Serious consequences of stroke Stroke and stroke refer to sudden cerebrovascular accidents, which can usually be divided into two categories: ischemic and hemorrhagic. Cerebral infarction is more common in clinical practice, accounting for about 80% or more, and cerebral hemorrhage accounts for about 20%. Blockage of blood vessels nourishing the brain leads to cerebral ischemia, i.e., cerebral infarction, which is usually caused by arterial thrombosis, arterial plaque, and atherosclerosis. Ischemia in the corresponding functional area of the brain can lead to dysfunction in that area, which manifests as sensory or motor impairment. However, arterial plaque and atherosclerosis can also lead to cerebral vascular rupture, especially in combination with hypertension, and when cerebral hemorrhage occurs usually the patient usually has severe headache. Both hemorrhagic and ischemic strokes are catastrophic to the sophisticated central nervous system, and in severe cases can lead to short-term loss of consciousness and death, coma with pulmonary infection, etc. Even if the acute phase of stroke does not result in death, it can cause varying degrees of damage to various aspects of brain function, such as inability to speak, slurred speech, paralysis of limbs, loss of mobility, decreased intelligence, and other serious sequelae. 5 warning signs Since the consequences of stroke are so serious, it will be of great help to stroke patients to know early symptoms of stroke and to seek medical attention in a timely manner. 1, a transient blackout or transient blurred vision The so-called blackout, that is, the sudden appearance of blackness in front of the eyes, can not see things, seconds or minutes to recover, or manifest transient visual impairment or visual field defects, mostly within an hour to recover on their own, generally do not leave after-effects. Blackout and blurred vision are mainly the manifestation of sudden ischemia of the brain, and some patients also have nausea, vomiting, dizziness and impaired consciousness, which are regarded as the precursors of stroke. 2.Yawning and fatigue may be caused by the relative lack of blood supply to the brain. If the narrowing of cerebral arteries gradually worsens and the respiratory center is deprived of oxygen, it will manifest as unconscious continuous yawning and fatigue and weakness. 3. Transient slurred speech or salivation symptoms A person who normally speaks normally and suddenly has trouble speaking and drools is a sign of stroke. 4. One-time unstable holding and lateral palsy Abnormal sensation in one of the limbs, inflexibility and reduced strength of the arms and legs, and inability to grip steadily. 5. Sudden headache The headache before a stroke is usually very severe, often accompanied by an increase in blood pressure, and can be described as a “headache to crack”. These seemingly insignificant symptoms may disappear within a few hours or days and leave no after-effects, but some are technically mild strokes, signaling that certain blood vessels in the brain have become undersupplied with blood, an important alarm signal that a stroke is about to occur. In order to avoid more serious strokes, people at risk for stroke or not should pay attention to it, improve cardiovascular and cerebrovascular examinations, seek specialist evaluation and health guidance, and carry out systematic and standardized prevention and treatment to avoid serious strokes. High-risk groups It is important to note that the onset of stroke is very sudden and may not necessarily have the typical onset of symptoms mentioned above, which requires friends with high-risk factors for stroke to pay more attention. 1, atherosclerosis, hypertension, diabetes, hyperlipidemia, obesity, 2, physical inactivity, alcoholism, smoking and other health problems; 3, advanced age, male – the older the age, the greater the probability of stroke, men are 1-1.5 times more likely to have a stroke than women; 4, family genetic predisposition The, hidden cerebrovascular malformations.
