Canine cognitive dysfunction (CCD) is a neurobehavioural syndrome affecting aged dogs. Using a large cross-sectional epidemiological study of older dogs, this study aimed to estimate the prevalence of CCD amongst community based dogs (mean age 11.67years; range 8-19.75) and to determine the rate of veterinary diagnosis amongst affected dogs. An 84-item questionnaire was used to obtain information across six behavioural domains. Of the eligible survey responses obtained (n=957) a randomly selected one-half (n=497) was used for this study. Using a provisional diagnosis based on 27 significant behavioural items, the prevalence rate of CCD was estimated to be 14.2%. This was in contrast with only 1.9% diagnosed with CCD by a veterinarian. There was an exponential increase in prevalence of CCD with age (R2=0.9435), but prevalence did not differ by breed size or between longevity groups. The prevalence rate of CCD reported here is consistent with previous findings, and further supports the contention that the majority of these dogs do not receive a formal diagnosis.
犬认知功能障碍（CCD）是一种影响老年犬的神经行为综合征。本研究通过一项针对老年犬的大型横断面流行病学研究，旨在评估社区内犬 CCD 的患病率（平均年龄 11.67 岁；范围 8-19.75 岁），并确定受影响犬的兽医诊断率。使用一个包含 84 个项目的问卷，获取六个行为领域的信息。在所获得的合格调查回复中（n=957），随机选择一半（n=497）用于本研究。基于 27 项有显著意义的行为项目，CCD 的患病率估计为 14.2%。这与兽医诊断出的 CCD 仅占 1.9%形成鲜明对比。CCD 的患病率随年龄呈指数增长（R2=0.9435），但与体型大小或长寿组之间无差异。这里报告的 CCD 患病率与之前的研究结果一致，并进一步支持了大多数这些犬只未得到正式诊断的说法。
