Graph analysis of verbal fluency test discriminate between patients with Alzheimer's disease, mild cognitive impairment and normal elderly controls

Frontiers in Aging Neuroscience, 2014
Verbal fluency is the ability to produce a satisfying sequence of spoken words during a given time interval. The core of verbal fluency lies in the capacity to manage the executive aspects of language.

A comparative study of verbal fluency in patients with paranoid schizophrenia, first grade relatives and healthy controls [PDF]

Archives of the Balkan Medical Union, 2019
Introduction. Cognitive impairment is a key symptom of schizophrenia and is known to be due to neurodevelopment changes. The aim of our study was to compare verbal fluency of patients with paranoid schizophrenia (PSch), first grade relatives (FGR) and

Impaired generation of new subcategories and switching in a semantic verbal fluency test in older adults with mild cognitive impairment

Frontiers in Aging Neuroscience, 2014
The semantic verbal fluency task is broadly used in the neuropsychological assessment of elderly subjects. Even some studies have identified differences in verbal fluency clustering and switching measures between subjects with normal aging and a clinical

Italian reference values and brain correlates of verbal fluency index – vs standard verbal fluency test – to assess executive dysfunction in ALS

Amyotrophic Lateral Sclerosis and Frontotemporal Degeneration, 2023
Objectives: In amyotrophic lateral sclerosis (ALS), verbal fluency index (Vfi) is used to investigate fluency accounting for motor impairment. This study has three aims: (1) to provide Vfi reference values from a cohort of Italian healthy subjects; (2) to assess the ability of Vfi reference values (vs standard verbal fluency test [VFT]) in ...

Neural correlates of executive function and working memory in the 'at risk mental state' [PDF]

Background and Aims: People with ‘prodromal’ symptoms have a very high risk of developing psychosis. We used functional MRI to examine the neurocognitive basis of this vulnerability.

Apathy and Reduced Speed of Processing Underlie Decline in Verbal Fluency following DBS

Behavioural Neurology, 2017
Objective. Reduced verbal fluency is a strikingly uniform finding following deep brain stimulation (DBS) for Parkinson’s disease (PD). The precise cognitive mechanism underlying this reduction remains unclear, but theories have suggested reduced ...

Exploring the Impact of Bilingualism on Semantic and Phonological Neuropsychological Tasks in Adults [PDF]

Journal of Rehabilitation Sciences and Research
Background: Numerous studies have yielded conflicting results concerning the disparities in verbal (semantic and letter) fluency between monolingual and bilingual individuals. Given the linguistic variations among bilinguals and the influence of cultural

Brainstem and Cerebellar Volume Loss and Associated Clinical Features in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Progressive Supranuclear Palsy (PSP) is a neurodegenerative ‘tauopathy’ with predominating pathology in the basal ganglia and midbrain. Caudal tau spread frequently implicates the cerebellum; however, the pattern of atrophy remains equivocal.

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.
