Abstract
PURPOSE The understanding of cognitive symptoms in patients with IDH-Mutant gliomas (IDH-Mut) is rapidly developing. In this article, we summarize the neuroscientific knowledge base regarding the influence of IDH-Mut tumors and their treatment on cognition and provide guidance regarding the management of these symptoms in patients. METHODS We performed a review of peer reviewed publications relevant to IDH-Mut glioma and cognitive outcomes and provide an overview of the literature as well as a case example to clarify management strategies. RESULTS At the time of presentation, patients with IDH-Mut gliomas have a favorable cognitive profile as compared with those with IDH-wild type (WT) tumors. The relatively low cognitive burden may reflect the slower growth rate of IDH-Mut tumors, which is less disruptive to both local and widespread neural networks. Human connectomic research using a variety of modalities has demonstrated relatively preserved network efficiency in patients with IDH-Mut gliomas as compared with IDH-WT tumors. Risk of cognitive decline from surgery can potentially be mitigated by careful integration of intra-operative mapping. Longer term cognitive risks of tumor treatment, including chemotherapy and radiation, are best managed by instituting neuropsychological assessment as part of the long-term care of patients with IDH-Mutant glioma. A specific timeline for such integrative care is provided. CONCLUSIONS Given the relative recency of the IDH-mutation based classification of gliomas, as well as the long time course of this disease, a thoughtful and comprehensive strategy to studying patient outcomes and devising methods of cognitive risk reduction is required.

Abstract
BACKGROUND Return to driving after an acquired brain injury (ABI) has been positively associated with return to employment, maintenance of social relationships, and engagement in recreational and other community activities. Safe driving involves multiple cognitive abilities in a dynamic environment, and cognitive dysfunction resulting from ABI can negatively impact driving performance. OBJECTIVE This manuscript examines the post-injury return-to-driving process, including performances on the in-office and on-road assessments, and the role of a rehabilitation neuropsychologist in helping patients resume driving. METHOD In this study, 39 of 200 individuals (approximately 20%) treated at an outpatient neurorehabilitation facility, who performed satisfactorily on a pre-driving cognitive screening, completed a behind-the-wheel driving test. RESULTS Of the 200 individuals, 34 (87%) passed the road test. Among the remaining five individuals who did not pass the road test, primary reasons for their failure included inability to follow or retain examiner directions primarily about lane position, speed, and vehicle control. The errors were attributable to cognitive difficulties with information processing, memory, attention regulation, and dual tasking.CONCLUSIONThe rehabilitation neuropsychologist contributed to the process by assessing cognition, facilitating self-awareness and error minimization, providing education about driving regulations and safety standards, and preparing for the road test and its outcomes.

Abstract
Cognitive symptoms occur in almost all patients with brain tumors at varying points in the disease course. Deficits in neurocognitive function may be caused by the tumor itself, treatment (surgery, radiation, or chemotherapy), or other complicating factors (e.g., seizures, fatigue, mood disturbance) and can have a profound effect on functional independence and quality of life. Assessment of neurocognitive function is an important part of comprehensive care of patients with brain tumors. In the neuro-oncology clinic, assessment may include cognitive screening tools and inquiry into subjective cognitive function. Neuropsychological assessment is an important adjunct to identify cognitive symptoms and can be used as an opportunity to intervene through transformative feedback and treatment planning. Preventative measures can be taken to reduce cognitive side effects of treatment, such as awake craniotomies with intraoperative mapping during neurosurgery or prophylactic measures during radiation therapy (e.g., hippocampal avoidance, neuroprotectant treatment with memantine). Rehabilitative therapies, including cognitive rehabilitation and computerized cognitive exercise, are options for managing cognitive problems in an individualized manner. Pharmacotherapy, including use of stimulant medications and acetylcholinesterase inhibitors, has shown benefits for patients with brain tumors when tailored to an individual's cognitive profile. Identification and management of co-occurring issues, such as sleep disturbance, fatigue, and depression, can also improve neurocognitive function. There are promising therapies under development that may provide new options for treatment in the future. Integrating careful assessment and treatment of cognition throughout the disease course for patients with brain tumors can improve functional outcomes and quality of life.

Abstract
Traffic accidents are a global concern due to the elevated mortality rates of both drivers and pedestrians. The World Health Organization declared 2011-2020 as the Decade of Action for Road Safety, endorsing initiatives to reduce traffic-related deaths. Yet, despite these incentives, fatal accidents still occur. Different studies have linked deficits in executive functions to risky driving attitudes and crashes. The present study focuses on demographic, cognitive and personality factors, related to the prefrontal cortex, that are characteristic of drivers prone to risky behavior behind the wheel. The penalty Points System was used to classify drivers as "safe", with no point loss over a two-year period, or "risky", with full point loss during the same interval. A neuropsychological assessment of prefrontal cognitive functions was carried out on each group to identify variables associated with safe and risky behavior. Neuropsychological indexes were obtained from a continuous performance task without cue (Simple Attention), a continuous performance task with cue (Conditioned Attention), the Tower of Hanoi test and the Neurologically-related Changes in Personality Inventory (NECHAPI). A Discriminant Analysis (DA) found that education level, reaction times in Simple and Conditioned Attention, learning errors in the Tower of Hanoi and vulnerability in the personality test, best predicted whether drivers were likely to be in the safe or risky group. Finally, a cross-validation analysis performed on the same sample correctly classified 87.5% of the drivers. These data suggest that prefrontal dysfunction contributes to risky behavior behind the wheel. The inclusion of cognitive programs to identify and train drivers with this propensity could reduce risky driving, and consequently, save lives on the road.

Abstract
PURPOSE OF REVIEW A detailed characterization of the nature of neurocognitive impairment in patients with brain tumors is provided, as well as considerations for clinical practice regarding neuropsychological assessment throughout the disease course. RECENT FINDINGS Neurocognitive impairment is common in patients with brain tumors and may result from the tumor itself, as a consequence of treatment, including surgery, chemotherapy, and radiation, or in association with supportive care medications (e.g., anticonvulsant and pain medications). Serial surveillance of neurocognitive functioning in this population can facilitate medical decision-making and inform recommendations to improve patient daily functioning and quality of life. Neuropsychological assessment is increasingly recognized as a critical component of the multidisciplinary care of patients with brain tumors and has already had practice-changing effects. Further understanding of genetic risk factors for neurocognitive decline along with the development of novel assessment and intervention strategies may further enhance functioning and general well-being in this patient population.

Abstract
BACKGROUND Virtual reality (VR) technology may provide an effective means to integrate cognitive and functional approaches to TBI rehabilitation. However, little is known about the effectiveness of VR rehabilitation for TBI-related cognitive deficits. In response to these clinical and research gaps, we developed Neurocognitive Driving Rehabilitation in Virtual Environments (NeuroDRIVE), an intervention designed to improve cognitive performance, driving safety, and neurobehavioral symptoms. OBJECTIVE This pilot clinical trial was conducted to examine feasibility and preliminary efficacy of NeuroDRIVE for rehabilitation of chronic TBI. METHODS Eleven participants who received the intervention were compared to six wait-listed participants on driving abilities, cognitive performance, and neurobehavioral symptoms. RESULTS The NeuroDRIVE intervention was associated with significant improvements in working memory and visual search/selective attention- two cognitive skills that represented a primary focus of the intervention. By comparison, no significant changes were observed in untrained cognitive areas, neurobehavioral symptoms, or driving skills. CONCLUSIONS Results suggest that immersive virtual environments can provide a valuable and engaging means to achieve some cognitive rehabilitation goals, particularly when these goals are closely matched to the VR training exercises. However, additional research is needed to augment our understanding of rehabilitation for driving skills, cognitive performance, and neurobehavioral symptoms in chronic TBI.

Abstract
OBJECTIVES Many older adults continue to drive following dementia diagnosis, with medical providers increasingly likely to be involved in addressing such safety concerns. This study examined electronic medical record (EMR) documentation of driving safety for veterans with dementia (N = 118) seen in Veterans Affairs primary care and interdisciplinary geriatrics clinics in one geographic region over a 10-year period. METHODS Qualitative directed content analysis of retrospective EMR data. RESULTS Assessment of known risk factors or subjective concerns for unsafe driving were documented in fewer than half of observed cases; specific recommendations for driving safety were evident for a minority of patients, with formal driving evaluation the most frequently documented recommendation by providers. CONCLUSION Utilizing data from actual clinical encounters provides a unique snapshot of how driving risk and safety concerns are addressed for veterans with dementia. This information provides a meaningful frame of reference for understanding potential strengths and possible gaps in how this important topic area is being addressed in the course of clinical care. CLINICAL IMPLICATIONS The EMR is an important forum for interprofessional communication, with documentation of driving risk and safety concerns an essential element for continuity of care and ensuring consistency of information delivered to patients and caregivers.

Abstract
Driving is a complex task, which can be broken down into specific cognitive processes. In order to determine which components contribute to drowsy driving impairments, the current study examined simulated driving and neurocognitive performance after one night of sleep deprivation. Nineteen professional drivers (age 45.3±9.1) underwent two experimental sessions in randomised order: one after normal sleep and one after 27h total sleep deprivation. A simulated driving task (AusEd), the psychomotor vigilance test (PVT), and neurocognitive tasks selected from the Cognitive Drug Research computerised neurocognitive assessment battery (simple and choice RT, Stroop Task, Digit Symbol Substitution Task, and Digit Vigilance Task) were administered at 10:00h in both sessions. Mixed-effects ANOVAs were performed to examine the effect of sleep deprivation versus normal sleep on performance measures. To determine if any neurocognitive tests predicted driving performance (lane position variability, speed variability, braking RT), neurocognitive measures that were significantly affected by sleep deprivation were then added as a covariate to the ANOVAs for driving performance. Simulated driving performance and neurocognitive measures of vigilance and reaction time were impaired after sleep deprivation (p<0.05), whereas tasks examining processing speed and executive functioning were not significantly affected by sleep loss. PVT performance significantly predicted specific aspects of simulated driving performance. Thus, psychomotor vigilance impairment may be a key cognitive component of driving impairment when sleep deprived. The generalisability of this finding to real-world driving remains to be investigated.

Abstract
OBJECTIVE To longitudinally investigate financial capacity (FC) following traumatic brain injury (TBI). DESIGN Longitudinal study comparing FC in cognitively healthy adults and persons with moderate to severe TBI at time of acute hospitalization (Time 1) and at 6 months postinjury (Time 2). SETTING Inpatient brain injury rehabilitation unit. PARTICIPANTS Twenty healthy adult controls and 24 adult persons with moderate to severe TBI. MAIN OUTCOME MEASURES Participants were administered the Financial Capacity Instrument (FCI-9), a standardized instrument that measures performance on 18 financial tasks, 9 domains, and 2 global scores. Between- and within-group differences were examined for each FCI-9 domain and global scores. Using control group referenced cut scores, participants with TBI were also assigned an impairment rating (intact, marginal, or impaired) on each domain and global score. RESULTS At Time 1, participants with TBI performed significantly below controls on the majority of financial variables tested. At Time 2, participants with TBI demonstrated within group improvement on both simple and complex financial domains, but continued to perform below adult controls on complex financial domains and both global scores. Group by time interactions were significant for four domains and both global scores. At Time 1, high percentages of participants with TBI were assigned either "marginal" or "impaired" ratings on the domains and global scores, with significant percentage increases of "intact" ratings at Time 2. CONCLUSIONS Immediately following acute injury, persons with moderate to severe TBI show global impairment of FC. Findings indicate improvement of both simple and complex financial skills over a 6-month period, but continued impairment on more complex financial skills. Future studies should examine loss and recovery of FC following TBI over longer time periods and a wider range of injury severity.

Abstract
PRIMARY OBJECTIVE The present study explored the possibility of predicting post-injury fitness to safe driving in patients with severe traumatic brain injury (TBI) (n = 66). METHODS AND PROCEDURE Sixteen different measures, derived from four domains (demo/biographic, medico-functional, neuropsychological, and psychosocial) were used as predictor variables, whereas driving outcomes were assessed in terms of driving status (post-TBI drivers versus non-drivers) and driving safety (number of post-TBI car accidents and violations). MAIN OUTCOMES AND RESULTS About 50% of the patients resumed driving after TBI. Compared to post-TBI non-drivers, post-injury drivers had shorter coma duration. With regard to driving safety, the final multiple regression model combined four predictors (years post-injury, accidents and violations before TBI, pre-TBI-risky-personality-index, and pre-TBI-risky-driving-style-index) and explained 72.5% of variance in the outcome measure. CONCLUSIONS Since the best three predictors of post-injury driving safety addressed patients' premorbid factors, the results suggest that in order to evaluate the actual possibility of safe driving after TBI, it would be advisable to consider carefully patients' pre-TBI histories.

Abstract
PRIMARY OBJECTIVE To analyse time-sharing strategies in patients with cerebral lesions when they performed everyday in-car tasks in real-life highway driving. A case-control study. METHODS AND PROCEDURES Thirteen male patients with brain damage and 11 healthy controls participated. The frequency and duration of glances at the in-car tasks, total time of eyes-off the road during tasks, speed and lateral displacement of the car were recorded. MAIN OUTCOMES AND RESULTS Long glances away from the road and consequent large lateral displacements were characteristic for patients with anterior damage, while the patients with more posterior lesions used frequent short glances at the in-car task. CONCLUSION Two different time-sharing strategies that appeared to be related to different aetiology were found in the patients, indicating different control of the driving task. It is proposed that standardized on-road dual tasks should be used for detecting problems in allocation of attention during driving.

Abstract
Cognitive impairments resulting from brain injury affect driving performance. The question of fitness to drive often arises during rehabilitation. Healthcare professionals need reliable criteria against which decisions about driving fitness can be made. Nouri et al. developed the Stroke Drivers Screening Assessment (SDSA), which was found predictive of on-road driving performance in stroke patients. The purpose of this study was to determine whether the SDSA, either alone or combined with other tests, predicted fitness to drive in brain injured people. Fifty-two participants were assessed on the SDSA plus additional cognitive tests. Their fitness to drive was examined on the public road. The SDSA predictions based on equations developed for stroke patients were not an accurate predictor of road test performance. Discriminant analysis was used to identify tests predictive of fitness to drive. Results indicated that a combination of the SDSA, the Stroop and the AMIPB Information Processing tasks correctly classified 87% of cases and may be useful predictors of driving fitness following brain injury. However, cross-validation on an independent sample of people with brain injury is required.

Abstract
PRIMARY OBJECTIVE This article presents a retrospective study on a group of survivors of severe traumatic brain injury with the purpose of discerning whether post-traumatic cognitive deficits prevent them from safely resuming driving and to see if holistic neurorehabilitation improves the rate of patients fit for returning to driving. METHODS AND PROCEDURES We studied 17 patients who had suffered severe traumatic brain injury (TBI) as measured by Glasgow Coma Scale scores. All subjects underwent a holistic, intensive and multidisciplinary neurorehabilitation program during a mean period of 10.53 months in the Centro de Rehabilitación de Daño Cerebral (CRECER)--Center for Brain Injury Rehabilitation--in Seville, Spain. Patients were divided into two different groups: drivers (patients who drove despite strong and repeated recommendations from the Center to desist from doing so when they began the rehabilitation program) and non-drivers (patients not driving at the time they began the rehabilitation program although they had a pre-injury driver's license). The FIM+FAM-Revised Scale [1] was administered both before commencing treatment and upon termination. RESULTS AND CONCLUSION (1) Patients showing physical functionality above 80% returned to driving, regardless of their cognitive and/or emotional deficits, and against doctor recommendations. (2) Severe TBI survivors that have not been certified as fit to drive are at increased risk for driving incidents other than collisions and traffic accidents. This is illustrated by significant incidents involving some of the subjects in our study that were due to disorientation, confusion and confrontations with people or situations. (3) We found that neurorehabilitation is worthwhile; after integral and multidisciplinary neurorehabilitation more than 70% of survivors of severe TBI can return to driving with regular safety. (4) We also suggest that laws be introduced to keep not-clinically-apt patients from driving.

Abstract
Most patients using hypnotics are ambulatory and presumably have a job and drive a car. Since driving a car is one of the most common but potentially dangerous daily activities, hypnotics should act rapidly when needed, but daytime sleepiness and other residual effects that may impair performance are unwanted. This review summarizes the effects of hypnotics on driving ability as determined with the on-the-road driving test during normal traffic. Supportive evidence from epidemiological data, and results from driving simulators and closed-road studies are also considered. On-the-road studies revealed that benzodiazepine hypnotics significantly impaired driving ability the morning following bedtime administration. Impairment was sometimes also significant in the afternoon (16-17 h after administration). Similar driving impairment was observed with zopiclone. However, the magnitude of impairment depends on various factors including the half-life and dosage of the drug, and the time after administration. The results from on-the-road driving studies are supported by evidence obtained in driving simulators and laboratory tests. Epidemiological data and on-the-road studies show that tolerance develops to the impairing effects of hypnotics. However, this is a slow process, and impairment may persist. Patients treated with benzodiazepine hypnotics or zopiclone should be cautioned when driving a car. Both zolpidem and zaleplon do not significantly affect driving performance the morning following bedtime administration. Middle-of-the-night administration of zolpidem significantly impairs driving ability in a dose-dependent manner. In contrast, zaleplon did not affect driving ability 4 h after middle-of-the-night administration.
