Evidence suggests that the Hooper Visual Organization Test (HVOT) has naming and executive components that vary in size depending on neurological diagnosis. The current study used a sample of individuals with Parkinson's disease (PD) to demonstrate for the first time that an executive measure can be the best predictor of HVOT performance. Forty-eight nondemented and nondepressed individuals with idiopathic PD completed the HVOT and other measures of visuoperception, executive function, and visual confrontation naming. Despite average performance on all neuropsychological measures, an executive measure, time to complete Trail-Making Test Part B minus time to complete Part A, was clearly the best predictor of HVOT performance in a standard regression. The pattern of neurocognitive predictors is unlike that reported in healthy individuals and other patient samples. This finding suggests that the presence of a neuropathological process can alter neurocognitive correlates even when performance is intact, and supports the contention that executive function is paramount in the cognitive profile associated with PD.

Introduction: There are unique technical and management challenges associated with living donor liver transplantation (LDLT) for Budd-Chiari Syndrome (BCS). The outcomes of LDLT for BCS in comparison to other indications remain unclear and warrant elucidation.
Methods: Data of 24 BCS patients who underwent LDLT between January 2012 and June 2019 were analyzed.

In dementia with Lewy bodies (DLB) recurrent visual hallucinations (VH) often coexist or occur consecutively to impaired visual perception. Since in-depth neuropsychological testing is time-consuming, and therefore, not routinely performed in clinical settings, we aimed to explore whether standard cognitive screening tests may be helpful to alert a clinician to the presence of VH in DLB by exploring association between visuo-spatial dysfunction and VH. The clock drawing, cube, and pentagons copying items from Montreal Cognitive Assessment and Mini-Mental State Exam and nonmotor Hooper visual organization test (HVOT) have been scored in DLB patients with and without VH using traditional and extended scoring methods.

Background And Purpose: Preventing subsequent falls in persons recovering from hip fracture is paramount. The Four Square Step Test (FSST) is a fast, easy measure of dynamic balance, with times more than 15 seconds previously associated with multiple fall risk in older adults. This study investigates among hip fracture patients (1) FSST performance, and how (2) unique population characteristics (such as fracture side) and (3) cognition impact FSST performance.

The Hooper Visual Organization Test (HVOT) is used to assess visual organization and visual synthesis. Psychometric studies reveal cultural biases and associations between demographic variables and test performance capable of compromising the test's clinical utility. The present study aimed to adapt the HVOT, explore the psychometric properties of this test, and develop regression-based norms for the Venezuelan population.

Deficient visual organization ability not only indicates possible brain dysfunctions but further affects an individual's daily activities. This study aimed to use functional magnetic resonance imaging (fMRI) to investigate the neural network contributing to visual organization abilities in children and adolescents. A two-choice version of the Hooper Visual Organization Test (T-HVOT) was adapted as the fMRI task for the present study.
