Perseverations and non-verbal confabulations on the Rey–Osterrieth Complex Figure Test in a fronto-temporal dementia single case study

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.
