Progressive supranuclear palsy and Parkinson's disease have distinct underlying
neuropathology, but both diseases affect cognitive function in addition to causing a …

Deficits in response inhibition are a central feature of the highly prevalent dysexecutive
syndrome found in Parkinson's disease (PD). Such deficits are related to a range of common …

Patients with Parkinson's disease (PD) show slowed movement initiation and can have
deficits in executive function, leading to impairments in controlling involuntary behavior. This …

Parkinson's disease (PD) is associated with a loss of central dopaminergic pathways in the
brain leading to an abnormality of movement, including saccades. In PD, analysis of …

Recent studies found evidence of impaired inhibition of saccades (fast eye movements) in
non-demented people with PD. It has been suggested that impaired eye movement control …

Studies of saccades in Parkinson's disease (PD) have seldom examined the influence of
cognitive status, ranging from normal cognition, through mild cognitive impairment, to …

Background: The integrity of frontal systems responsible for voluntary control and their
interaction with subcortical regions involved in reflexive responses were studied in patients …

In an attempt to distinguish and define the altered cognitive processes associated with
Parkinson's disease (PD), we examine and try to dissociate the components of an effective …

Objective: To describe ideomotor apraxia in patients with corticobasal degeneration and
those with progressive supranuclear palsy, two parkinsonian disorders that are often …

Lateral visually-guided saccades were studied electro-oculographically in 40 patients with
progressive supranuclear palsy (PSP) in order to increase understanding of the …
