Abstract:
We describe the case of a patient with late onset fronto-temporal dementia (FTD), who presented with typical personality changes, but also perseverative and confabulatory behaviors while performing the Rey-Osterrieth Complex Figure Test. We hypothesize that the progressive atrophy of orbitobasal, medial, and dorsolateral frontal cortices may give rise to both confabulations and perseverations in the non-verbal domain. In agreement with previous studies, reporting atypical profiles, this case report underlines the clinical heterogeneity of FTD. Authors declare that they have no conflicts of interest.
