Can intracerebral hemorrhage occur without hypertension?

Brain hemorrhage can occur even without hypertension, such as in individuals with atherosclerosis, cerebrovascular malformations, or hyperlipidemia.

1. Atherosclerosis

If a person suffers from long-term atherosclerosis, it may lead to vascular aging and hardening, which under certain conditions could result in brain hemorrhage.

2. Cerebrovascular Malformation

If the walls of cerebral blood vessels undergo degeneration or inflammatory reactions, arterial blood may flow directly into venous circulation without passing through a normal capillary network, leading to cerebrovascular malformation. Under certain triggering factors, this condition makes arterial rupture and subsequent brain hemorrhage more likely.

3. Hyperlipidemia

If a patient frequently drinks alcohol, smokes, and lacks regular physical activity, it may lead to abnormal lipid levels and cause hyperlipidemia. As the disease progresses, amyloid changes in the blood vessels may develop, increasing the risk of brain hemorrhage.
