There are many causes of cerebral hemorrhage. In most cases, given that patients themselves already have certain underlying diseases, such as hypertension, diabetes, coronary heart disease, and arteriosclerosis, the blood pressure remains high over a long period. This causes the blood vessels to be in a constant state of tension. Over time, the vessels' ability to regulate and contract gradually weakens. When certain triggers occur, such as the patient experiencing fatigue, mental stress, or emotional excitement, the blood pressure temporarily spikes, exceeding the vessels' regulatory capacity, leading to the rupture of the blood vessels and causing cerebral hemorrhage.
