Final answer:
Neck rigidity, bloody cerebrospinal fluid, and headache are associated with a hemorrhagic stroke in the brain.
Step-by-step explanation:
The symptoms of neck rigidity, bloody cerebrospinal fluid, and headache are associated with a hemorrhagic stroke in the brain. A hemorrhagic stroke occurs when a blood vessel in the brain is damaged and begins to bleed. The accumulated blood puts pressure on the surrounding brain tissue, causing symptoms such as a stiff neck, headache, and changes in cerebrospinal fluid.
