Results Among 1 083 patients, polyneuritis, acute myelitis, periodic paralysis men with A blood type; trigminal neuralgia, Guillian-Barre syndrome were more of ten in men with B blood type;virus meningitis, women with sclerosis, epilepsy, myasthenia gravis,were more of ten in women with O blood type. The A, B, O blood type component proportions of the diseases mentioned above and those of the normal people have statistic differences. This presents that people with A, B, or O blood type are easy to catch those diseases.
