Low blood pressure does not cause cerebral hemorrhage, the most common cause of cerebral hemorrhage is high blood pressure, especially when the blood pressure suddenly rises, due to the cerebral blood vessels that the pressure suddenly increases, easy to lead to the rupture of cerebral arteries, which will lead to the formation of cerebral hemorrhage, low blood pressure is also low pressure of blood vessels in the brain, which is not prone to cerebral blood vessels rupture, the causes of cerebral hemorrhage are not only only high blood pressure, high blood pressure is only the most common cause, there are also cerebral arterial High blood pressure is only the most common cause, but also cerebral arterial malformation and cerebral aneurysm, which are also easy to cause cerebral hemorrhage. Most of the cerebral hemorrhages in elderly patients are related to high blood pressure, but for the cerebral hemorrhage in young people, it is very likely to be caused by cerebral arterial malformation or cerebral artery aneurysm rupture, which has no relationship with hypertension, if it is purely low blood pressure, without arterial malformation or aneurysm, the probability of occurrence of cerebral hemorrhage is almost zero.
