The causes of cerebral hemorrhage in thalamus with normal blood pressure include aneurysm, cerebral vascular malformation, malignant tumor, abnormal coagulation function, physiological factors and so on. 1. Aneurysm: rupture of aneurysm can lead to cerebral hemorrhage, and the blood pressure may be normal before the onset. 2. Cerebral vascular malformation: cerebral vascular malformation has the possibility of cerebral hemorrhage under the condition of normal blood pressure. 3. malignant tumor: malignant tumor in the brain grows faster, which will lead to hypoxia, ischemia and necrosis of tumor tissues, resulting in cerebral hemorrhage. 4. Abnormal coagulation function: patients with previous hemophilia, coagulation dysfunction or long-term use of anticoagulant drugs will lead to the occurrence of cerebral hemorrhage. 5. Physiological factors: In individual cases, frequent late nights as well as emotional excitement can lead to cerebral hemorrhage. Appearance of blood pressure normal thalamus cerebral hemorrhage is recommended to seek medical advice as soon as possible.
