Factors Influencing Medical Treatment Of Parkinsonism With Conflicting DaT Imaging: The Cleveland Clinic Experience (P5.273)
CONCLUSIONS:This study demonstrated a greater likelihood of continuing PD medications despite a negative scan than withholding PD medications despite a positive scan. The most common reason for continuing medications despite a negative scan was good response to dopaminergic medications regardless of the working diagnosis. Clinical impressions outweighed DaT scan results in a small proportion of patients.Disclosure: Dr. Nacopoulos has nothing to disclose. Dr. Oravivattanakul has nothing to disclose.

Clinical routine use of dopamine transporter imaging in 516 consecutive patients
Abstract [123I]-FP-CIT is a single photon emission computed tomography (SPECT) ligand showing in vivo the loss of dopaminergic terminals in the brain and is now available in the market. Despite several systematic studies in clinically inconclusive cases, the use of such imaging in clinical routine is scarcely reported. We analyzed 516 files of subjects with movement disorders who were consecutively examined using [123I]-FP-CIT scan and determined whether the use of imaging was appropriate and if it improved clinical diagnosis or care of the patient. In addition, we determined if appropriate use was related to subs...

Stroke Care Services in Singapore During COVID-19 Pandemic —A National Perspective
Stroke is a significant cause of admission to Singapore's acute care hospitals. Because of the current COVID-19 pandemic, there have been major changes in the stroke care system. On calling for the public ambulance, those suspected to have COVID-19 infection are taken to the National Center for Infectious Diseases. Otherwise, on arrival at the emergency room, all cases with fever or respiratory symptoms [COVID-19 suspect patients (CSPs)] are evaluated separately by staff wearing full personal protective equipment (PPE). Triage is not delayed. CSPs needing hyperacute therapies are sent to a specially prepared scanner; if no...

Non-Neurologist Self Assessment of Emergency Neurology Proficiency and Interest in a Novel Intensive Stroke and Neurocritical Care Training Program: The X-CHANGE Program (P1.045)
Conclusions:Hospital based non-neurology physicians have significant exposure to critically ill neurological patients. Many are not comfortable with important fundamental skills, such as the neurological exam. There is strong interest in a proposed intensive training program emphasizing bedside teaching. Based upon these results, we are developing a formal intensive training program for practicing non -neurology physicians called the "Cross-disciplinary Cerebrovascular HospitAl NeuroloGy Education" program.Disclosure: Dr. Yee has nothing to disclose.

Impact of the implementation of the AAN epilepsy quality measures on the medical records in a university hospital
Background: The American Academy of Neurology (AAN) suggested eight quality measures to be observed at every patient visit. The aim of this work is to compare the percentage of documentation of each measure before and after the implementation of a new worksheet in a third-level center. Methods: Quasi-experimental study including medical records filled by medical school seniors and junior residents supervised by an epileptologist. The authors surveyed 80 consecutive charts of people with epilepsy who were seen in the outpatient clinic before and after the intervention. McNemar change test was used to compare the percentages...

The relationship between the subjective experience of real-world cognitive failures and objective target-detection performance in visual search
Cognition. 2021 Sep 27;217:104914. doi: 10.1016/j.cognition.2021.104914. Online ahead of print.ABSTRACTVisual search is a common occurrence in everyday life, such as searching for the location of keys, identifying a friend in a crowd, or scanning an upcoming intersection for hazards while driving. Visual search is also used in professional contexts, such as medical diagnostic imaging and airport baggage screening. These contexts are often characterised by low-prevalence or rare targets. Here we tested whether individual differences in the detection of targets in visual search could be predicted from variables derived from ...

Tracking longitudinal evolution of amyotrophic lateral sclerosis using multimodal MRI (S13.005)
Conclusions:We found a significant progression of brain damage in ALS patients, evolving as a widespread structural network degeneration. Our results suggest that MRI provides a powerful tool to track in vivo the disease spreading evolution related to pathological propagation in ALS.Study Supported by: Italian Ministry of Health (#RF-2010-2313220).Disclosure: Dr. Ferraro has nothing to disclose.

Stroke Mortality And Its Predictors In Nigeria: Results Of A Hospital-Based Study (P2.120)
Conclusion: The 30-day case fatality rate among our stroke patients is high while the independent predictors of this outcome are severity of stroke on admission and presence of complications. Continuing health education of the public on stroke recognition and the need for early hospital presentation is necessary while optimal management of cases in a stroke care unit is advocated in order to improve outcome.Disclosure: Dr. Wahab has nothing to disclose.

Pseudoneglect during object search in naturalistic scenes
Exp Brain Res. 2023 Aug 23. doi: 10.1007/s00221-023-06679-6. Online ahead of print.ABSTRACTPseudoneglect, that is the tendency to pay more attention to the left side of space, is typically assessed with paper-and-pencil tasks, particularly line bisection. In the present study, we used an everyday task with more complex stimuli. Subjects' task was to look for pre-specified objects in images of real-world scenes. In half of the scenes, the search object was located on the left side of the image (L-target); in the other half of the scenes, the target was on the right side (R-target). To control for left-right differences in t...

A novel computational model to probe visual search deficits during motor performance
Successful execution of many motor skills relies on well-organized visual search (voluntary eye movements that actively scan the environment for task-relevant information). Although impairments of visual search that result from brain injuries are linked to diminished motor performance, the neural processes that guide visual search within this context remain largely unknown. The first objective of this study was to examine how visual search in healthy adults and stroke survivors is used to guide hand movements during the Trail Making Test (TMT), a neuropsychological task that is a strong predictor of visuomotor and cognitiv...

Top-down and bottom-up sources of eye-movement guidance during realistic scene search in Alzheimer’s disease.
Conclusions: Our study shows the importance of top-down and bottom-up guidance, and their integration, in improving search in AD patients. It suggests that precise target cues and, even more, highly salient targets may act as environmental supports that enhance attentional processing and search performance.

The effect of cerebral asymmetries and eye scanning on pseudoneglect for a visual search task.
Abstract Pseudoneglect is the tendency for the general population to over-attend to the left. While pseudoneglect is classically demonstrated using line bisection, it also occurs for visual search. The current study explored the influence of eye movements and functional cerebral asymmetry on asymmetries for visual search. In Experiment 1, 24 participants carried out a conjunction search for a target within a rectangular array. A leftward advantage for detecting targets was observed when the eyes were free to move, but not when they were restricted by short exposure durations. In Experiment 2, the effect of functio...
