The Cats & Dogs Test: a web-based platform to detect early visual processing deficits in Parkinson’s disease
Objective: To develop a sensitive web-based test to detect visuo-perceptual deficits in patients with Parkinson’s disease as an early marker of dementia. Background: Up to…Defective visual perception in patients with Lewy body disease: assessment of hallucinations with pareidolia test.
Objective: Hallucination is a common feature in patients with advanced Parkinson’s disease(PD) and dementia with Lewy bodies (DLB). Background: The pareidolia test is a tool…Cognitive Mechanisms of Visual Dysfunction in Non-Demented PD Patients (PD-ND)
Objective: To conduct a comprehensive assessment of visual processing in PD-ND, including tests of low-level vision sensitive to retinal pathology, high-level object/spatial vision reflecting ventral/dorsal…Cognition, vision and visuo-cognition in gait in Parkinson’s disease
Objective: This study examined the selective but overlapping roles of cognition and vision in gait in Parkinson's disease (PD). To address this we studied; 1)…Impaired color discrimination selectively associates with postural instability and gait difficulties in Parkinson’s disease
Objective: To investigate the relationship between impairments of the cardinal motor impairments and color discrimination deficits in Parkinson's disease (PD). Background: Previous studies have shown…Frequency and characteristics of diplopia in non-demented patients with Parkinson’s disease
Objective: To assess the frequency of diplopia and its relation to motor and non-motor symptoms in a cross sectional sample of non-demented patients with idiopathic…Optic nerve integration as a visuospatial cognitive predictor in Parkinson’s disease
Objective: To explore the microstructural integrity of the optic nerve and its role as a cognitive predictor in patients with de novo Parkinson's disease (PD)…Defective visual perception in patients with Parkinson’s disease: The impairment of preattentive visual processing in the normal intellectual patients
Objective: In the previous conference, we reported that the impairment of preattentive visual processing could be detected even among subjects considered to have normal cognitive…Sensitivity of people with Parkinson’s to different intensities of emotions (SPiEs)
Objective: To characterise the ability of individuals with Parkinson's to discriminate the six universal facial expressions. Background: People with Parkinson's (PwP) tend to have difficulty…Quantifiable changes in cortical visual processing in patients with Parkinson’s disease but no cognitive impairment
Objective: To demonstrate quantifiable differences in cortical visual processing in patients with Parkinson's disease with no evidence of dementia, as compared to controls. Background: Visual…
