Describe the features of a brain and spinal cord infection.?

Go to ER now: An infection of the area surrounding the brain can cause meningitis- fever, stiff neck, headache, and changes in conciousness. An infection within the brain itself is encephalitis- causing changes in personality, level of conciousness, and even seizures or other abnormal movements. These conditions are both very life-threatening, but treatable, and should be evaluated by a physician immediately.
