Overview
Causes
Causes of Intracranial Hemorrhage
Intracranial bleeding occurs when a blood vessel in the head is ruptured or leaks. It can result from physical trauma (as occurs in head injury) or nontraumatic causes (as occurs in hemorrhagic stroke) such as a ruptured aneurysm (ballooning blood vessel).
Extradural Hemorrhage
- Rarely hemorrhage from a fracture gap, injured venous sinus or arachnoid villi
- Skull fracture
Intracerebral Hemorrhage
- After cerebral infarction
- Aneurysm
- Angioma
- Anticoagulant medication
- Hypertension
- Perinatal hemorrhage
- Trauma
- Tumor
- Risk Factors
- Anticoagulation medication
- Decreased platelet count
- Disseminated Intravascular Coagulation (DIC)
- Embolic strokes
- Hemophilia
- Hypertension
- Sickle Cell Anemia
Subarachnoid Hemorrhage
- Alcoholism
- Arteriovenous malformation
- Bacterial Endocarditis
- Brain tumor
- Fibromuscular Dysplasia (FMD)
- Hemorrhagic diathesis
- Hypertension
- Infections
- Leukemia
- Mycotic aneurysm
- Other aneurysms
- Other connective tissue diseases
- Polycystic kidney disease
- Ruptured intracerebral aneurysm
- Smoking
Subdural Hemorrhage
- Acute subdural hematoma
- Subacute subdural hematoma
- Usually due to head injury
- Risk Factors
- Alcoholism
- Anticoagulant medication
- Any disorder that results in falling
- Chronic use of aspirin
- Head injury
- Very young or advanced age
