Not clear: Pacns (primary angiitis of the central nervous system) is rare enough that conclusions cannot yet be made with great certainty. It seems to have an autoimmune component which may well be genetic. It is also more common in certain parts of the world which is also suggestive. Inflamed blood vessels may cause seizures, headaches, stroke, spinal cord syndromes, or mental deterioration.
