Subarachnoid hemorrhage

Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space. This space is the area between the arachnoid membrane and the pia mater, which surrounds the brain.

Symptoms may include a severe headache, vomiting, loss of consciousness, fever, and sometimes seizures. Neck stiffness or neck pain are also common.^[1] SAH causes troponin levels to rise.
