这项研究探讨了终身双语对维持认知功能和延迟老年痴呆症症状发作的影响。该样本是从228名被转介到记忆诊所的认知投诉患者的记录中选择的。最终样本包括184名被诊断患有痴呆症的患者，其中51%的人会说双语。双语者比单语者晚4年出现痴呆症状，所有其他指标都相当。此外，两组中的一部分患者在诊断后4年内的简易精神状态检查（MMSE）评分下降率相同，表明发病年龄发生变化，进展率无变化。(c)2006爱思唯尔有限公司保留所有权利。
This study examined the effect of lifelong bilingualism on maintaining cognitive functioning and delaying the onset of symptoms of dementia in old age. The sample was selected from the records of 228 patients referred to a Memory Clinic with cognitive complaints. The final sample consisted of 184 patients diagnosed with dementia, 51% of whom were bilingual. The bilinguals showed symptoms of dementia 4 years later than monolinguals, all other measures being equivalent. Additionally, the rate of decline in Mini-Mental State Examination (MMSE) scores over the 4 years subsequent to the diagnosis was the same for a subset of patients in the two groups, suggesting a shift in onset age with no change in rate of progression.
