Is Depression or Apathy Playing a Key Role in Predicting Financial Capacity in Parkinson's Disease with Dementia and Frontotemporal Dementia?

(1) Background: Depression and apathy both affect cognitive abilities, such as thinking, concentration and making decisions in young and old individuals. Although apathy is claimed to be a core feature of Parkinson's disease (PD) and frontotemporal dementia (FTD), it may occur in the absence of depression and vice versa. Thus, the aim of this study is to explore whether depression or apathy better predict financial capacity performance in PD and FTD as well as in nondemented participants. (2) Methods: Eighty-eight participants divided into three groups (PD, FTD and non-demented participants) were examined with the Mini-Mental State Examination (MMSE) and the Legal Capacity for Property Law Transactions Assessment Scale (LCPLTAS)-Full and short form. The Geriatric Depression Scale informant version (GDS-15) and the Irritability-Apathy Scale (IAS) we completed by caregivers. (3) Results: The results indicated that both PD and FTD patients' general cognitive functioning and financial capacity performance is negatively influenced by apathy and not by depression. (4) Conclusions: Differences in financial capacity performance indicate that apathy should not be disregarded in clinical assessments. Further studies on larger PD and FTD populations are necessary in order to investigate the decisive role of mood factors on financial capacity impairment.

Automated summary

The study found that both PD and FTD patients' general cognitive functioning and financial capacity performance are negatively influenced by apathy rather than depression. This suggests that apathy should not be overlooked in clinical assessments, and further research is needed to explore the impact of mood factors on financial capacity impairment in larger populations with PD and FTD.
