The Cats-and-Dogs Test Predicts Cognitive Impairment in Parkinson’s Disease in a Diverse Population
Objective: To determine whether the Cats-and-Dogs visuoperceptual task (CnD) predicts cognitive impairment (CI) in Parkinson’s disease (PD) in a diverse population in East London and…Atypical Parkinsonian Syndromes Presenting with Homonymous Hemianopsia
Objective: We present here two cases of atypical parkinsonism with visual field loss to help increase recognition and drive research efforts forward to elucidate the…The Cats-and-Dogs Test Predicts Cognitive Impairment in Parkinson’s Disease in a Diverse Population
Objective: To establish whether a visuoperceptual tool (the Cats-and-Dogs test) can predict cognitive impairment (CI) in people with Parkinson’s disease (PwP) in a diverse population.…Abnormal Top-down Perceptual Modulation Drives Visual Hallucinations in Parkinson’s Disease
Objective: Assess performance on computerized illusions across PD patients with (PD_Hal) and without (PD_NonHal) history of visual hallucinations and explore underlying cortical substrates. Background: In…Gastrointestinal Dysbiosis and Clinical Outcomes in Parkinson’s Disease
Objective: To evaluate whether patients with PD exhibit 1) a bloom in sulfate-reducing bacteria based on the detection of hydrogen-sulfide (H2S) during lactulose breath testing…Deep learning-based Prediction of Visual Dysfunction in Parkinson’s Disease from 31 Brain Regions of Interest using Quantitative Diffusion MRI
Objective: Compare the performance of deep learning and machine learning models trained on quantitative diffusion measurements in the prediction of visual dysfunction in Parkinson’s Disease…One-year longitudinal decline in spatial location memory in Huntington’s disease
Objective: This study aimed to assess the capacity of the adapted version of the object-location memory task [1] to detect and monitor early Huntington’s Disease (HD) deficits.…The crucial role of the visual system on the PISA syndrome in Parkinson’s disease
Objective: Patients with Parkinson's disease (PD) are significantly disturbed in their daily life when accompanied by the PISA syndrome (PS) of lateral bending. Background: We…Piloting the Cats-and-Dogs tool as a culture-fair test for sensory processing impairment in Parkinson’s disease
Objective: This pilot explored the feasibility and culture-fairness of a psychophysical visuoperceptual test for Parkinson’s disease (PD) in a multicultural population in East London. Background:…Pareidolias and color discrimination deficits differently correlate with cognitive dysfunction in prodromal Lewy body disease
Objective: To investigate color discrimination ability and complex visual illusions known as pareidolias, and their associating factors in patients with iRBD compared to PD and…
