Frontotemporal dementia (FTD) is an entity that includes a group of neurodegenerative disease with symptoms predominantly pertaining to deficits in behavior, executive function (or) language. FTD is one of the most common type of dementia before 65 years of age and is one of the most underdiagnosed dementia as most often the symptoms overlap with psychiatric manifestations. Based on the clinical features, FTD is further subdivided into behavioral variant FTD (Bv-FTD) and primary progressive dementia (PPA). We searched PubMed, MEDLINE, and Google Scholar for articles about FTD disease published in English between January 1, 1975 till 2018. We used the search terms "frontotemporal dementia," "Fronto temporal dementia-motor neuron disease," "dementia," "cognition," "behavioral variant," and "primary progressive aphasia.
额颞叶痴呆（FTD）是一种包含一组神经退行性疾病的实体，其症状主要涉及行为、执行功能（或）语言方面的缺陷。FTD 是 65 岁之前最常见的痴呆类型之一，也是最被低估的痴呆类型之一，因为大多数情况下，症状与精神表现重叠。根据临床特征，FTD 进一步细分为行为变异型 FTD（Bv-FTD）和原发性进行性痴呆（PPA）。我们在 PubMed、MEDLINE 和 Google Scholar 上搜索了 1975 年 1 月 1 日至 2018 年期间发表的关于 FTD 疾病的英文文章。我们使用了以下搜索词：“额颞叶痴呆”、“额颞叶痴呆-运动神经元病”、“痴呆”、“认知”、“行为变异”和“原发性进行性失语症”。
