Executive anosognosia in progressive supranuclear palsy versus Parkinson's disease.

ABSTRACT:

Background

Executive function deficits are common among patients with Parkinson's disease (PD) and progressive supranuclear palsy (PSP). Executive function refers to higher-order cognitive processes thought to involve fronto-striatal circuits. Some patients with executive deficits may be unable to recognize or report them, a condition we refer to as executive anosognosia.

Objective

To conduct a comparative analysis of executive anosognosia in patients diagnosed with PSP and PD.

Methods

We compared an objective neuropsychological assessment (ONA) of composite executive function (ONA-CEF), which includes semantic and phonemic verbal fluency, as well as two sub-scores from the Wisconsin Card Sorting Test, with patient- and informant-reported rating scales. We used the Dy
