Behavioral disturbances in the course of frontotemporal dementia
Abstract
Background: Behavioral disturbances are prominent in frontotemporal dementia (FTD), and their occurrence has been the topic of several investigations. Nonetheless, the prevalence and severity of behavioral disturbances of patients with FTD in different degrees of dementia severity have rarely been studied. Objective: The aim of this study was to assess and compare the prevalence and severity of behavioral disturbances in patients with mild FTD and in patients with moderate/severe dementia. Methods: We included 21 outpatients with mild FTD [Clinical Dementia Rating (CDR) = 1] and 19 patients with moderate or severe dementia (CDR = 2 or 3) in this study. Behavioral disturbances were assessed using the Neuropsychiatric Inventory (NPI). Results: We found a statistically significant difference in the total NPI scores between patients with mild FTD and patients with moderate or severe FTD, the latter scoring higher. Apathy was the most prevalent symptom in both patient groups (90.5 and 100%). Except appetite and eating disturbance, which appeared in 77.8% of the patients with moderate/severe dementia, all other symptoms were clearly less common (<50%). Conclusion: The results highlight the variability of behavioral disturbances in mild and moderate/severe stages of FTD.

During disease progression in bvFTD, behavioral symptoms may vary, initial behaviors fade whilst new behaviors appear, showing behavioral trajectories are not linear.
“During disease progression in bvFTD behavioral symptoms may vary, initial behaviors fade whilst new behaviors appear, showing behavioral trajectories are not linear (Diehl-Schmid et al., 2006).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
