The prevalence rate of Huntington disease in County Donegal between 1961 and 1991 showed a decrease from 4.4 to 1.6 per 100,000 population. Emigration and reduction in family size probably account for the progressive decline in prevalence. Over the same time period in the rest of Europe, prevalence has declined only gradually, or has remained static.
1961年至1991年间,多尼戈尔郡亨廷顿病的患病率从每10万人中的4.4例降至1.6例。移民和家庭规模缩小可能是患病率逐渐下降的原因。在同一时期,欧洲其他地区的患病率仅逐渐下降,或保持稳定。
