An epidemiological survey of primary dementia syndromes was conducted in the city of Bra (26287 residents) in the Piedmont region. All the patients for whom a diagnosis of senile dementia had already been recorded together with the cases coming to light as a result of a questionary circulated to general practitioners and neuropsychiatrists were subjected to a broad battery of neuropsychological tests. The prevalence rate proved to be 255 (+/- 61) per 100 000 of the population and 2028 (+/- 476) per 100 000 of the over 65s. Close attention was paid to dements living in nursing facilities. Factors favoring institutionalisation were: advanced age, severe motor impairment and female sex. No correlation between severity or dementia and institutionalisation was found.
在皮埃蒙特地区的布拉市（有26287名居民）开展了一项原发性痴呆综合征的流行病学调查。所有已记录为老年性痴呆的患者，以及通过向全科医生和神经精神科医生发放调查问卷而发现的病例，都接受了一系列广泛的神经心理学测试。结果显示，每10万人口中的患病率为255（±61），65岁以上人群中每10万人口的患病率为2028（±476）。研究密切关注了住在护理机构中的痴呆患者。促使患者入住护理机构的因素有：高龄、严重的运动功能障碍和女性。未发现痴呆严重程度与入住护理机构之间存在相关性。
