The frontotemporal dementia (FTD) consortium criteria (2011) emphasise the importance of distinguishing possible and probable behavioural variant FTD (bvFTD). A significant number of possible patients with bvFTD do not show functional decline and remain with normal neuroimaging over time, thus exhibiting the bvFTD phenocopy syndrome. A neurodegenerative nature is unlikely but an alternative explanation is missing. Our aim was to detect psychiatric conditions underlying the bvFTD phenocopy syndrome after extensive evaluation.
