Evaluation of Semantic Space Search Metrics in Phonemic Fluency: Comparison among Basal Ganglia Disorders and Healthy Controls
Objective: Phonemic verbal fluency reflects executive function and involves both within-category lexical retrieval (cluster size) and switching between categories. We compared semantic search behavior in…Differentiation of Parkinsonian Syndromes Using Cognitive Strategies and Associations with Non-tremor Motor Progression
Objective: This study aims to investigate whether cognitive strategies on verbal fluency tasks differentiate Parkinson’s disease (PD) from Progressive Supranuclear Palsy (PSP) and healthy adults, and are associated with the progression of clinical motor symptoms in Parkinson’s…Longitudinal cognitive variability in isolated and probable REM sleep behaviour disorder using the Trail Making Test
Objective: To evaluate whether longitudinal changes in cognitive performance are present in isolated REM sleep behaviour disorder (iRBD) and probable RBD (pRBD, positive single-item RBD…Executive Dysfunction as a Determinant of Functional Impairment in Parkinson’s Disease
Objective: To evaluate executive function across cognitive stages of Parkinson’s disease and examine its association with functional impairment. Background: Executive dysfunction is one of the…Psychotic Symptoms and Cognitive Impairment in Huntington’s Disease
Objective: To investigate the clinical and cognitive correlates of psychotic symptoms in patients with Huntington’s disease (HD). Background: Psychiatric manifestations are common in HD, but…Depressive Symptoms and Functional Impairment in Huntington’s Disease A Brazilian Cohort Study
Objective: To investigate the prevalence of psychiatric manifestations in Huntington’s disease (HD) and examine their association with functional disease stages. Background: HD is an autosomal…Psychiatric Symptoms and Quality of Life in Huntington’s Disease Evidence from a Brazilian Cohort
Objective: To investigate the association between psychiatric manifestations and perceived quality of life in patients with Huntington’s disease (HD). Background: HD is a progressive neurodegenerative…Acute administration of methylphenidate modulates functional connectivity during the processing of irrelevant stimuli in Parkinson’s disease patients
Objective: Examine the effects of a single dose of methylphenidate (MPD), on event-related functional connectivity (FC), in patients with Parkinson’s disease (PD). Background: Recent studies…Embodying a Sixth Soft Finger. How Wearing a Supernumerary Robotic Digit Impacts our Body Schema
Objective: To assess whether a supernumerary robotic digit can enter into the user’s body schema, thereby altering bodily self-representation and proprioceptive awareness. Background: Stroke is…Changes in Inhibitory Control Differentiate Progressive Supranuclear Palsy from Early Parkinson’s Disease
Objective: To describe distinct type of errors and frequency of perseverative errors in executive, memory, language, and attentional tasks in PSP and PD. Background: Progressive…
