作者以往曾发现在荷兰、挪威西部多发性硬化(MS)的流行和发病率增加。故对1953～1982年在荷兰的311例MS患者进行了分析。其中254例为缓解或缓解进行型,57例为慢性进行型。在可能的MS患者中进行型(40.4%)比缓解型(16.5%)多;而肯定或很可能的MS患者中,则缓解型(83.5%)比进行型(59.6%)多。一、发病率:进行型每年发病率较稳定,平均1～3例,而缓解型有所增加,1953～1960年每年3～5例;1970～1980年为每年10～14例。以每隔3年观察来看,亦示进行型患者仍少,而缓解型有所增加。1970年以前缓解型两性患者每年均平行的增加,以
The authors have previously found an increase in the prevalence and incidence of multiple sclerosis (MS) in the Netherlands and western Norway. Therefore, from 1953 to 1982 in the Netherlands 311 cases of MS patients were analyzed. Among them, 254 were relieved or remission type and 57 were chronic type. Among the possible patients with MS, 40.4% were more likely to be remitting (16.5%) than those with remission (16.5%), while those who were positive or likely were more likely to have remission (83.5%) than those who did (59.6%). First, the incidence: incidence of annual incidence of more stable, an average of 1 to 3 cases, while remission type has increased from 1953 to 1960, 3 to 5 cases per year; 1970 to 1980 for 10 to 14 cases per year. In every 3 years of observation, also showed that the type of patients is still less, while the remission type has increased. Remission type bisexual patients before 1970 each year an increase in parallel to
