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 ...

Qualitative Deficits in Verbal Fluency in Parkinson’s Disease with Mild Cognitive Impairment: A Clinical and Neuroimaging Study

Journal of Parkinson’s Disease, 2021
Background: Mild cognitive impairment (MCI) in Parkinson’s disease (PD) is considered a risk factor for PD with dementia (PDD). Verbal fluency tasks are widely used to assess executive function in PDD.

White matter microstructure and verbal fluency

Brain Structure and Function, 2022
AbstractPoor performance on verbal fluency tasks is associated with an increased risk of post-stroke cognitive impairment. Grey matter regions supporting verbal fluency have been identified via lesion–symptom mapping, but the links between verbal fluency and white matter structure remain less well described.

Subthalamic Nucleus Stimulation Does Not Have Any Acute Effects on Verbal Fluency or on Speed of Word Generation in Parkinson’s Disease

Parkinson's Disease, 2019
Background. Deep brain stimulation of the subthalamic nucleus (STN-DBS) has been shown to be generally safe from a cognitive perspective, with consistent evidence that the major impact of STN-DBS in Parkinson’s disease (PD) is on verbal fluency ...

A Pilot Study of Verbal Fluency in the Zulu Speaking Population with Preliminary Application to Traumatic Brain Injury

South African Journal of Communication Disorders, 1999
This study investigated the semantic verbal fluency (VF) abilities of non-neurologically impaired (NNI) Zulu speaking subjects in order to obtain normative data for this population.

Brain structure associations with phonemic and semantic fluency in typically-developing children

Developmental Cognitive Neuroscience, 2021
Verbal fluency is the ability to retrieve lexical knowledge quickly and efficiently and develops during childhood and adolescence. Few studies have investigated associations between verbal fluency performance and brain structural variation in children ...

Use of a modified version of the switching verbal fluency test for the assessment of cognitive flexibility

Dementia & Neuropsychologia
Objective: Verbal fluency tests are widely used for the assessment of executive functions. However, traditional versions of the test depend on several cognitive factors beyond these components.

Quantitative EEG and Verbal Fluency in DBS Patients: Comparison of Stimulator-On and -Off Conditions

Frontiers in Neurology, 2019
Introduction: Deep brain stimulation of the subthalamic nucleus (STN-DBS) ameliorates motor function in patients with Parkinson's disease and allows reducing dopaminergic therapy.

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...
