Headache (secondary) by Brain Angiitis (cerebral asculitis)
Cerebral vasculitis or brain angiitis is the inflammation of blood vessel wall in the brain, resulting in reduced blood flow in the brain or blockade of the blood vessel, as seen in stroke. Therefore, cerebral vasculitis causes headache and brain ischemia. The headache is mild/moderate, accompanied with signs of neurological disorders such as behavior, movement disorder, or altered or loss of consciousness. There may be fever. Please go to see your doctor right way if you have above symptoms.
