Cerebral hemorrhage, commonly known as cerebral hemorrhage, is a kind of “stroke” and a common serious brain complication in middle-aged and elderly patients with hypertension. The most common causes are hypertension, cerebral atherosclerosis, intracranial vascular malformation, etc. It is often triggered by exertion, emotional excitement and other factors, so most of the sudden onset in the activity. It is one of the fatal diseases in middle-aged and elderly people because of its rapid onset, dangerous condition and high mortality rate. As the world is gradually aging, cerebral hemorrhage has become a more widespread acute and serious disease, and the annual death of patients due to cerebral hemorrhage accounts for about 20% of all deaths, which seriously threatens people’s health. So what are the causes of cerebral hemorrhage? Causes 1, external factors: climate change, clinically found that the occurrence of cerebrovascular disease is particularly common in seasonal changes, such as spring and summer, autumn and winter junction season, modern medicine believes that seasonal changes and changes in external temperature can affect the normal metabolism of human neuroendocrine, change the blood viscosity, plasma fibrin, adrenaline are elevated, capillary spasmodic contraction and increased brittleness. Within a short period of time, the intracranial blood vessels cannot adapt to such a more obvious change, that is, there are fluctuations in blood pressure, which eventually leads to the occurrence of cerebral hemorrhage. 2, emotional changes: emotional changes are another important cause of cerebral hemorrhage, including extreme sadness, excitement, fear, etc. We always find that most patients with cerebral hemorrhage have a history of emotional agitation before the onset of the disease, and there has even been a study done to confirm that nearly 30% of patients in the clinic are angry, emotional agitation leading to cerebral hemorrhage. The reason for this is mainly due to a short period of emotional change when there is sympathetic excitement, heart rate increases, blood pressure suddenly increased, the original fragile blood vessel rupture caused. 3, bad habits: smoking has more serious health effects on the human body is recognized by the World Health Organization, long-term smoking can make the body’s vascular fragility increased, the ability to withstand fluctuations in blood pressure is prone to cerebral vascular rupture. And long-term alcohol consumption can cause vasoconstriction diastolic adjustment disorders, and vascular endothelial damage, intravascular lipid deposition, making the vascular conditions become poor, prone to cerebral hemorrhage. In addition, frequent overexertion and lack of physical exercise can also increase blood viscosity and destroy vascular conditions, leading to cerebral hemorrhage. The above is only a list of the more common triggers in our clinic, not all patients must have these triggers, some patients due to the role of long-term various underlying diseases, can also occur in the quiet state of cerebral hemorrhage, the pathological mechanism of the occurrence of cerebral hemorrhage is more complex, especially patients who often have the above triggers need to be cautious, to prevent serious complications.
