Symptoms of Hemorrhagic Stroke

Cerebral Hemorrhage Symptoms. Symptoms of a cerebral, or parenchymal, hemorrhage typically begin very suddenly and evolve over several hours and include:

• Headache
• Nausea and vomiting
• Altered mental states
• Seizures

Subarachnoid Hemorrhage. When the hemorrhage is a subarachnoid type, warning signs may occur from the leaky blood vessel a few days to a month before the aneurysm fully develops and ruptures. Warning signs may include:

• Abrupt headaches
• Nausea and vomiting
• Sensitivity to light
• Various neurologic abnormalities. Seizures, for example, occur in about 8% of patients.

When the aneurysm ruptures, the stroke victim may experience:

• A terrible headache
• Neck stiffness
• Vomiting
• Altered states of consciousness
• Eyes may become fixed in one direction or lose vision
• Stupor, rigidity, and coma
