Frontotemporal Dementia - Current Concepts.

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.
