Frontotemporal dementia

Abstract

Frontotemporal dementia (FTD) is a neurodegenerative disorder of insidious onset, and the term encompasses several entities. It is mostly sporadic. Epidemiologically, its prevalence as a dementia is third behind Alzheimer's disease and dementia with Lewy bodies (Bang et al., 2018). The incidence of FTD is around 1.61-4.1 cases per 100,000 people annually (Coyle-Gilchrist et al., 2016), and the most common age of onset is in the sixth decade (Kelley and El-Khouri, 2016). This case report highlights the fact that the presentation of frontotemporal dementia can be subtle, and can present a diagnostic difficulty when differentiating it from vascular dementia and other cognitive disorders.
