Abstract

Background: Executive dysfunction is the common thread between pure cortical dementia like the behavioral variant of frontotemporal dementia (bvFTD) and subcortical dementia like Parkinson's disease dementia (PDD). Although there are clinical and cognitive features to differentiate cortical and subcortical dementia, the behavioral symptoms differentiating these 2 conditions are still not well known.

Objective: To evaluate the behavioral profile of bvFTD and PDD and compare them to find out which behavioral symptoms can differentiate between the two.

Methods: Twenty consecutive patients with bvFTD (>1 year after diagnosis) and 20 PDD patients were recruited according to standard diagnostic criteria. Behavioral symptoms were collected from the reliable caregiver by means of a set of questionnaires and then compared between the 2 groups.

Results: bvFTD patients had more severe disease and more behavioral symptoms than PDD. bvFTD patients were different from PDD patients due to their significantly greater: loss of basic emotion (p < 0.001, odds ratio [OR] 44.33), loss of awareness of pain (p < 0.001, OR 44.33), disinhibition (p < 0.001, OR 35.29), utilization phenomenon (p = 0.008, OR 22.78), loss of taste discrimination (p < 0.001, OR 17), neglect of hygiene (p = 0.001, OR 13.22), loss of embarrassment (p = 0.003, OR 10.52), wandering (p = 0.004, OR 9.33), pacing (p = 0.014, OR 9), selfishness (p = 0.014, OR 9), increased smoking (p = 0.014, OR 9), increased alcohol consumption (p = 0.031, OR 7.36), social avoidance (p = 0.012, OR 6.93), mutism (p = 0.041, OR 5.67), and failure to recognize objects (p = 0.027, OR 4.33). The bvFTD patients were also significantly less suspicious (p = 0.001, OR 0.0295), less inclined to have a false belief that people were in their home (p = 0.014, OR 0.11) and had fewer visual illusions/hallucinations (p = 0.004, OR 0.107) than PDD patients.

Conclusion: Behavioral symptoms are helpful to distinguish bvFTD from PDD, and thus also cortical dementia with frontal-lobe dysfunction from subcortical dementia.

额颞叶痴呆行为变异型与帕金森氏症痴呆行为特征的比较研究

背景：执行功能障碍是额颞叶痴呆行为变异型（bvFTD）等纯皮质痴呆与帕金森病痴呆（PDD）等皮质下痴呆之间的共同点。虽然有一些临床和认知特征可以区分皮质性痴呆和皮质下痴呆，但区分这两种疾病的行为症状仍不十分清楚：评估 bvFTD 和 PDD 的行为特征，并将两者进行比较，以找出哪些行为症状可以区分这两种疾病：方法：根据标准诊断标准，连续招募 20 名 bvFTD 患者（确诊后超过 1 年）和 20 名 PDD 患者。结果：与 PDD 相比，bvFTD 患者的病情更严重，行为症状更多。bvFTD 患者与 PDD 患者的不同之处在于：基本情感丧失（p < 0.001，比值比 [OR] 44.33）、痛觉丧失（p < 0.001，OR 44.33）、抑制（p < 0.001，OR 35.29）、利用现象（p = 0.008，OR 22.78）、味觉辨别能力丧失（p < 0.001，OR 17）、忽视卫生（p = 0.001，OR 13.22）、窘迫感丧失（p = 0.003，OR 10.52）、游荡（p = 0.004，OR 9.33）、踱步（p = 0.014，OR 9）、自私（p = 0.014，OR 9）、吸烟增加（p = 0.014，OR 9）、饮酒增加（p = 0.031，OR 7.36）、社交回避（p = 0.012，OR 6.93）、缄默症（p = 0.041，OR 5.67）和无法识别物体（p = 0.027，OR 4.33）。与 PDD 患者相比，bvFTD 患者的多疑性（p = 0.001，OR 0.0295）、误认家中有人的倾向（p = 0.014，OR 0.11）和视觉错觉/幻觉（p = 0.004，OR 0.107）也明显减少：行为症状有助于区分bvFTD和PDD，因此也有助于区分额叶功能障碍的皮质痴呆和皮质下痴呆。

期刊介绍： This open access and online-only journal publishes original articles covering the entire spectrum of cognitive dysfunction such as Alzheimer’s and Parkinson’s disease, Huntington’s chorea and other neurodegenerative diseases. The journal draws from diverse related research disciplines such as psychogeriatrics, neuropsychology, clinical neurology, morphology, physiology, genetic molecular biology, pathology, biochemistry, immunology, pharmacology and pharmaceutics. Strong emphasis is placed on the publication of research findings from animal studies which are complemented by clinical and therapeutic experience to give an overall appreciation of the field. Dementia and Geriatric Cognitive Disorders Extra provides additional contents based on reviewed and accepted submissions to the main journal Dementia and Geriatric Cognitive Disorders Extra .
