Subjective Cognitive Decline Could Help Predict Parkinson’s Dementia, Study Contends


Increasing evidence suggests that subjective cognitive decline is associated with Alzheimer’s disease pathology and with an increased risk for future dementia development. However, the clinical value of subjective cognitive decline in Parkinson’s disease (PD-SCD) is unclear. The aim of the present work was to characterize PD-SCD and its progression to dementia.

Statistical analyses revealed that language domain and, especially memory domain are good predictors of dementia.

Conclusions

The present investigation is the first to conduct a long-term follow-up study of PD-SCD and its relationship with the development of dementia. The results provide relevant data about the characterization of SCD in PD patients and show that PD-SCD is a risk factor for progression to dementia
