Neuropsychological assessment with lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ+) individuals: Practice, education, and training survey.

Objective: We sought to describe the LGBTQ + related education, training, and clinical practice of independently licensed neuropsychologists in the United States and to identify factors that predict affirmative neuropsychological practices. We hypothesized that LGBTQ + identity, female gender, more recent training, and extent of LGBTQ + education/training would predict use of LGBTQ + practice guidelines. Method: A workgroup of clinical psychologists with experience in LGBTQ + psychology and neuropsychology developed a survey to identify personal and professional factors that predict affirmative neuropsychological testing practices. The survey was distributed through professional organizations and listservs between August and September 2021 with 118 responses meeting inclusionary criteria. Results: The majority of participants identified as heterosexual (70.3%) and cisgender (97.5%), and most (48-63%) received LGBTQ + training post-licensure. Between 19% and 32% of participants reported never completing LGBTQ + specific education. Consistent with our hypotheses, factors predicting affirmative clinical practice behaviors were LGBTQ + education/training, and personal background (sexual minority status, female/feminine gender, and years since degree). Other significant factors included prior experience with LGBTQ + patients and primary patient population (child vs. adult). Qualitative responses indicated varying values, attitudes, and knowledge regarding collection of LGBTQ + information and modification of clinical practice. Conclusions: Neuropsychologists underutilize affirming practices as evidenced by low rates of querying pronouns, knowing whether LGBTQ + health information is available at their institutions, and adjusting evaluation and feedback approaches. We provide specific training and education recommendations to increase knowledge and skills and to address beliefs about LGBTQ + health that can serve to promote affirmative neuropsychological practice.

Affirmative neuropsychological practice with transgender and gender diverse individuals and communities.

Objective: To provide guidance and resources on how to practice culturally safe and humble neuropsychology with transgender and gender diverse (TGD) individuals and communities. Methods: We gathered a multidisciplinary team of clinicians with relevant professional and/or lived experience to review pertinent literature, discuss important concepts, and identify key resources. From this process, we outline practical steps to advance gender affirmative neuropsychological practice. Results: Professional awareness and knowledge regarding how to gather context-relevant, gender identity information is critical. TGD individuals form a heterogenous group; a one-size-fits-all approach is not adequate. It is incumbent upon neuropsychologists to engage in clinical and research practices in a manner that does not perpetuate gender minority stress and trauma. Creating an open, safe environment of care requires intentionality and careful thinking to determine what information is relevant for a particular referral question. We provide recommendations and resources for neuropsychologists. Conclusion: When neuropsychologists are proactive, responsible, and intentional, they can better provide individualized, person-centered, and trauma-informed care to TGD individuals.

Conducting neuropsychological assessment with transgender individuals.

OBJECTIVE: The purpose of this paper is to provide an overview of helpful clinical practices when working with transgender adult individuals. METHOD: While the number of openly transgender individuals appears to be growing with society's increased acceptance and awareness, many neuropsychologists have had few opportunities to gain experience with this patient population. In this article, we review the existing literature as it relates to clinical neuropsychological practice. RESULTS: We describe important terminology, ideals for creating an environment of respect, and how existing clinical guidelines for transgender individuals may apply to neuropsychology. In addition, we review the primary steps in the assessment process and provide a set of principles and recommendations for conducting neuropsychological assessments with transgender patients. CONCLUSIONS: There is a paucity of guidance in the field for working with transgender individuals. This article represents a step forward in the dialog and we look forward to future research that develops appropriate normative information, increases understanding of psychosocial factors, and better appreciates the range of hormonal influences for transgender individuals.

Retrospective and Prospective Memory Among OEF/OIF/OND Veterans With a Self-Reported History of Blast-Related mTBI.

OBJECTIVES: To evaluate prospective and retrospective memory abilities in Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) Veterans with and without a self-reported history of blast-related mild traumatic brain injury (mTBI). METHODS: Sixty-one OEF/OIF/OND Veterans, including Veterans with a self-reported history of blast-related mTBI (mTBI group; n=42) and Veterans without a self-reported history of TBI (control group; n=19) completed the Memory for Intentions Test, a measure of prospective memory (PM), and two measures of retrospective memory (RM), the California Verbal Learning Test-II and the Brief Visuospatial Memory Test-Revised. RESULTS: Veterans in the mTBI group exhibited significantly lower PM performance than the control group, but the groups did not differ in their performance on RM measures. Further analysis revealed that Veterans in the mTBI group with current PTSD (mTBI/PTSD+) demonstrated significantly lower performance on the PM measure than Veterans in the control group. PM performance by Veterans in the mTBI group without current PTSD (mTBI/PTSD-) was intermediate between the mTBI/PTSD+ and control groups, and results for the mTBI/PTSD- group were not significantly different from either of the other two groups. CONCLUSIONS: Results suggest that PM performance may be a sensitive marker of cognitive dysfunction among OEF/OIF/OND Veterans with a history of self-reported blast-related mTBI and comorbid PTSD. Reduced PM may account, in part, for complaints of cognitive difficulties in this Veteran cohort, even years post-injury. (JINS, 2018, 24, 324-334).

Fatigue - but not mTBI history, PTSD, or sleep quality - directly contributes to reduced prospective memory performance in Iraq and Afghanistan era Veterans.

OBJECTIVE: Memory problems that affect daily functioning are a frequent complaint among Veterans reporting a history of repetitive mild traumatic brain injury (mTBI), especially in cohorts with comorbid PTSD. Here, we test the degree to which subjective sleep impairment and daytime fatigue account for the association of PTSD and self-reported mTBI history with prospective memory. METHOD: 82 Veterans with and without personal history of repeated blast-related mTBI during deployment were administered the Clinician Administered PTSD Scale (CAPS), Memory for Intentions Test (MIST), Patient Health Questionnaire-9 (PHQ-9), Neurobehavioral Symptom Inventory (NSI), and the Pittsburgh Sleep Quality Index (PSQI). Relationships between self-reported mTBI, PTSD, self-reported poor sleep and daytime fatigue, and MIST performance were modeled using partial least squares structural equation modeling (PLS-SEM). RESULTS: Reported daytime fatigue was strongly associated with poorer prospective memory performance. Poor subjective sleep quality was strongly and positively associated with reported daytime fatigue, but had no significant direct effect on prospective memory performance. PTSD diagnosis and self-reported mTBI history were only associated with prospective memory via their impact on subjective sleep quality and daytime fatigue. CONCLUSIONS: Results suggest that daytime fatigue may be a mediating factor by which both mTBI and PTSD can interfere with prospective memory. Additional attention should be given to complaints of daytime fatigue, independent of subjective sleep quality, in the clinical care of those with a self-reported history of mTBI, and/or PTSD. Further research into whether interventions that decrease daytime fatigue lead to improvement in prospective memory and subjective cognitive functioning is warranted.

Sleep and its associations with perceived and objective cognitive impairment in individuals with multiple sclerosis.

Problems with sleep and cognitive impairment are common among people with multiple sclerosis (MS). The present study examined the relationship between self-reported sleep and both objective and perceived cognitive impairment in MS. Data were obtained from the baseline assessment of a multi-centre intervention trial (NCT00841321). Participants were 121 individuals with MS. Nearly half (49%) of participants met the criteria for objective cognitive impairment; however, cognitively impaired and unimpaired participants did not differ on any self-reported sleep measures. Nearly two-thirds (65%) of participants met the criteria for 'poor' sleep, and poorer sleep was significantly associated with greater levels of perceived cognitive impairment. Moreover, the relationships between self-reported sleep and perceived cognitive impairment were significant beyond the influence of clinical and demographic factors known to influence sleep and cognitive functioning (e.g. age, sex, education level, disability severity, type of MS, disease duration, depression and fatigue). However, self-reported sleep was not associated with any measures of objective cognitive impairment. Among different types of perceived cognitive impairment, poor self-reported sleep was most commonly related to worse perceived executive function (e.g. planning/organization) and prospective memory. Results from the present study emphasize that self-reported sleep is significantly and independently related to perceived cognitive impairment in MS. In terms of clinical implications, interventions focused on improving sleep may help improve perceived cognitive function and quality of life in this population; however, the impact of improved sleep on objective cognitive function requires further investigation.

Cognitive Impairment and Community Integration Outcomes in Individuals Living With Multiple Sclerosis.

OBJECTIVES: To determine the association between unique domains of cognitive impairment and community integration in individuals with multiple sclerosis (MS), and to determine the contributions of cognitive impairment to community integration beyond the influence of demographic and clinical variables. DESIGN: Cross-sectional analysis of objective neuropsychological assessment and self-report data. Data were collected during baseline assessment of a randomized, multisite controlled trial of ginkgo biloba for cognitive impairment in MS. Hierarchical regression analyses examined the association between subjective and objective measures of cognitive impairment and 3 domains of community integration, adjusting for relevant covariates. SETTING: Two Veterans Affairs medical center MS clinics. PARTICIPANTS: Adults (N=121; ages 24-65y) with a confirmed MS diagnosis. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Primary outcomes were scores on the Home Integration (CIQ-H), Social Integration (CIQ-S), and Productivity (CIQ-P) domains of the Community Integration Questionnaire (CIQ). RESULTS: Cognitive impairment was associated with lower scores on the CIQ-H and CIQ-S, but not the CIQ-P. Greater levels of subjective cognitive impairment were associated with lower scores on the CIQ-H and CIQ-S. Greater levels of objective cognitive impairment, specifically slower processing speed and poorer inhibitory control, were related to lower CIQ-S scores. Subjective and objective measures of cognitive impairment were significantly and independently associated with CIQ-S. CONCLUSIONS: Objective cognitive impairment may interfere with participation in social activities. Subjective cognitive impairment is also important to assess, because individuals who perceive themselves to be cognitively impaired may be less likely to participate in both home and social activities. Clinical interventions to enhance community integration in individuals with MS may benefit from addressing objective and subjective cognitive impairment by integrating cognitive rehabilitation approaches with self-efficacy-enhancing strategies.

Napping on the Night Shift: A Study of Sleep, Performance, and Learning in Physicians-in-Training.

BACKGROUND: Physicians in training experience fatigue from sleep loss, high workload, and working at an adverse phase of the circadian rhythm, which collectively degrades task performance and the ability to learn and remember. To minimize fatigue and sustain performance, learning, and memory, humans generally need 7 to 8 hours of sleep in every 24-hour period. METHODS: In a naturalistic, within-subjects design, we studied 17 first- and second-year internal medicine residents working in a tertiary care medical center, rotating between day shift and night float every 4 weeks. We studied each resident for 2 weeks while he/she worked the day shift and for 2 weeks while he/she worked the night float, objectively measuring sleep by wrist actigraphy, vigilance by the Psychomotor Vigilance Task test, and visual-spatial and verbal learning and memory by the Brief Visuospatial Memory Test-Revised and the Rey Auditory-Verbal Learning Test. RESULTS: Residents, whether working day shift or night float, slept approximately 7 hours in every 24-hour period. Residents, when working day shift, consolidated their sleep into 1 main sleep period at night. Residents working night float split their sleep, supplementing their truncated daytime sleep with nighttime on-duty naps. There was no difference in vigilance or learning and memory, whether residents worked day shift or night float. CONCLUSIONS: Off-duty sleep supplemented with naps while on duty appears to be an effective strategy for sustaining vigilance, learning, and memory when working night float.

The utility of regression-based norms in interpreting the minimal assessment of cognitive function in multiple sclerosis (MACFIMS).

The Minimal Assessment of Cognitive Function in Multiple Sclerosis (MACFIMS) is a consensus neuropsychological battery with established reliability and validity. One of the difficulties in implementing the MACFIMS in clinical settings is the reliance on manualized norms from disparate sources. In this study, we derived regression-based norms for the MACFIMS, using a unique data set to control for standard demographic variables (i.e., age, age2, sex, education). Multiple sclerosis (MS) patients (n = 395) and healthy volunteers (n = 100) did not differ in age, level of education, sex, or race. Multiple regression analyses were conducted on the performance of the healthy adults, and the resulting models were used to predict MS performance on the MACFIMS battery. This regression-based approach identified higher rates of impairment than manualized norms for many of the MACFIMS measures. These findings suggest that there are advantages to developing new norms from a single sample using the regression-based approach. We conclude that the regression-based norms presented here provide a valid alternative to identifying cognitive impairment as measured by the MACFIMS.

Influence of recruitment and participation bias in neuropsychological research among MS patients.

The potential influence of recruitment context in neuropsychological (NP) research is seldom addressed in the literature. Our experience with a previous large-scale study of MS cognitive impairment led us to speculate that referral questions and motivation bias significantly impact conclusions drawn from NP testing. We re-analyzed data from Benedict et al. (2006) and compared the results obtained across three groups of patients: paid research volunteers, clinical patients undergoing evaluation for routine monitoring of cognitive status, and clinical patients referred for diagnostic clarification, determination of disability benefits, and other more complex issues. Research volunteers were significantly younger and less frequently cognitively impaired compared to the clinical groups, greatly affecting prevalence estimates (45.6 to 65.6%). Significant correlations between depression and cognitive impairment were present only among the research volunteers. NP testing significantly predicted vocational outcomes in all groups. These results suggest that greater attention should be paid to the reasons patients agree to participate in NP testing.

A 3-year longitudinal study of cognitive impairment in patients with primary progressive multiple sclerosis: speed matters.

BACKGROUND: The few controlled longitudinal studies of cognitive performance in MS patients all provide evidence of deterioration in at least a subset of the patients sampled. Only one of these studies has focused on primary progressive MS, and little attention has been paid to the specific domains of cognitive functioning that change over time. The present study examined three principal cognitive domains in samples of primary progressive MS patients and healthy controls followed over a period of 3 years. METHODS: A battery of neuropsychological tests that included measures of strategic problem solving, verbal memory, and information processing speed was administered annually to 24 MS patients and 25 controls. RESULTS: MS patients' performance on measures of processing speed showed significantly greater decline over the 3-year period than did that of controls. Similar results were not observed in the case of problem solving or verbal memory. There was no evidence of more dramatic decline occurring in patients who were initially classified as cognitively impaired relative to those who were unimpaired at baseline. However, this failure may have been influenced by differential attrition from the sample; more impaired patients were less likely to complete the study. CONCLUSION: Overall the results support the contention that information processing speed is the domain most sensitive to the impact of multiple sclerosis on cognitive functioning over time.

Information processing deficits in multiple sclerosis: a matter of complexity.

This study examined the relationship between processing speed (PS) and working memory (WM), as measured by performance on an n-back task, in relapsing-remitting multiple sclerosis (RRMS) patients. Simple PS was defined as reaction time (RT) on the 0-back task and complex PS was defined as RT on both the 1-back and 2-back tasks. Participants were administered all three n-back tasks (0-, 1-, and 2-back). Total correct responses, total dyads, and RTs were recorded. As expected, RT for all participants slowed as WM load increased. MS patients had slower RTs than controls across all tasks, and the difference between groups for RT was greatest during the 2-back task. When RT for simple PS (0-back) was parsed from the 1- and 2-back tasks, MS patients still showed impaired complex PS compared to controls. MS patients also made significantly fewer total correct responses and had fewer dyads than controls only on the 2-back task. These findings suggest that both WM and PS deficits are present in RRMS, and that as WM demand increases (from 1- to 2-back) both PS and WM deficits become more prominent.

Validity of the Wisconsin Card Sorting and Delis-Kaplan Executive Function System (DKEFS) Sorting Tests in multiple sclerosis.

Multiple sclerosis (MS) is a disease of the central nervous system that causes cognitive impairment with a frequency of roughly 50%. While processing speed and memory defects are most commonly observed, a substantial number of patients also have deficiency in higher executive ability. Two tests, the Wisconsin Card Sorting Test (WCST) and the Sorting Test from the Delis-Kaplan Executive Function System (DKEFS), have been recommended for evaluation of neuropsychological impairment in MS. We investigated the validity of these tests in 111 MS patients and 46 age- and education-matched controls. MS patients performed more poorly on both measures, but only the DKEFS discriminated the groups after controlling for depression. Both tests were modestly or strongly correlated with MRI indices of brain atrophy or lesion burden and discriminated between employed and disabled patients. While both tests appear to have good validity in the MS population, the availability of alternative forms makes the DKEFS an attractive alternative to the WCST, as was suggested by a consensus panel.

Working memory deficits in multiple sclerosis: comparison between the n-back task and the Paced Auditory Serial Addition Test.

Working memory (WM) deficits are common in multiple sclerosis (MS). The Paced Auditory Serial Addition Test (PASAT) is used frequently to measure WM in clinical settings. The n-back paradigm is used often in experimental studies of WM. One unique component of the n-back task is that it provides a measure of reaction time (RT), an additional behavioral index of processing speed and task difficulty. Despite the use of both tasks to measure WM, their common variance has not been documented. We tested 32 MS patients and 20 controls; performance measures were obtained for both tasks. Compared with controls, MS patients generally had poorer performance on both the PASAT and n-back task. MS patients also had slower RTs on the n-back than controls and showed more slowing than controls as a function of WM load. Correlational analyses showed a high correspondence between performance measures on the PASAT and n-back. Principal components analysis pointed to a common feature of the PASAT, n-back, and specific other neuropsychological measures, that is, processing speed. Although the PASAT and n-back were shown to have a significant amount of shared variance, each test has specific advantages and disadvantages for use in clinical populations.

The relationship between perceived and objective cognitive functioning in multiple sclerosis.

The relationship between perceived cognitive functioning and objective cognitive functioning was studied in 221 patients with multiple sclerosis. Perceptions of global cognitive functioning as well as perceptions of performance on specific cognitive tests were assessed. Patients' perceptions of global cognitive functioning in their daily lives were unrelated to their objective performance on the full cognitive test battery. However, patients' perceptions of their performance on specific tasks correlated with their objective performance on those tasks, even though they underestimated their performance on these tasks. The present study also evaluated predictors of patients' perceived cognitive functioning. Depression, anxiety, fatigue, and level of disability predicted perceptions of global cognitive functioning, whereas objective cognitive performance did not. These results add to our understanding of patients' expressed concerns regarding their cognitive functioning in the wake of multiple sclerosis, suggesting that such concerns should be interpreted with caution by clinicians.

The association between cognitive impairment and physical disability in multiple sclerosis.

BACKGROUND: The association between cognitive impairment and physical disability was examined in a larger, more representative sample of patients with multiple sclerosis (MS) than in previous studies. METHOD: Two hundred and fifty-three patients attending an MS clinic were assessed with respect to physical disability using the Expanded Disability Status Scale and cognitive impairment using a battery of neuropsychological tests. RESULTS: Physical disability correlated with duration of disease; cognitive impairment did not. Virtually all measures derived from the cognitive battery were significantly correlated with physical disability. Three measures of speeded information processing and one involving delayed recall of verbal material were unique predictors of disability status. The relationship between cognitive impairment and physical disability was equivalent for patients with shorter (< 3 years) versus longer (> 10 years) disease duration. Cognitive impairment correlated with the rate of disability progression as reflected by the progression index. CONCLUSION: Cognitive impairment is more closely associated with physical disability than most previous studies indicate. This relationship appears to be stable throughout the duration of MS, although this conclusion is qualified by the cross-sectional design of the study. Further attention should be paid to cognitive impairment as a possible predictor of the rate of patients' physical decline.

Cognitive impairment in relapsing and primary progressive multiple sclerosis: mostly a matter of speed.

Based on the assumption that cognitive impairment in MS is consistent with subcortical dementia, a battery of neuropsychological tests was assembled that included measures of executive function (Tower of London and Wisconsin Card Sorting Test), verbal learning and memory (a paired associates learning test), and speeded information processing (Stroop Color Word Interference Test). The battery was administered to patients with relapsing and primary progressive MS and to healthy controls. Differences between patients and controls occurred on several of the measures. However, when differences with respect to fatigue and depression were statistically controlled, the only differences that remained significant involved measures relating to the speed of information processing. Patients performed more slowly than controls, with the disparity being greater for relapsing patients than for those with primary progressive disease. The slowing was evident on measures of automatic as well as controlled processing and regardless of whether speed was an explicit feature of successful performance or recorded unobstrusively while the patient concentrated on planning a correct solution to a problem. Parallels were noted between cognitive slowing associated with MS and that of normal aging.

The cognitive performance of patients with multiple sclerosis during periods of high and low fatigue.

The objective of this study was to examine whether multiple sclerosis (MS)-related fatigue affects patients' cognitive performance. Thirty patients who had substantial fatigue in conjunction with MS and who reported marked diurnal variability in the severity of their fatigue were tested on two occasions: during a period of high fatigue and during a period of relatively low fatigue. The order of these sessions was counterbalanced across patients. During both sessions, patients completed a questionnaire concerning their present state of fatigue and a battery of neuropsychological tests of planning, selective attention, and paired associate learning. Although patients confirmed greater fatigue during the period of high fatigue and felt they had performed more poorly during this period, there were no differences in cognitive performance that could be attributed to fatigue. Instead, all subjects showed improvement from the first to the second session regardless of whether the latter entailed a period of high or low fatigue. In contrast to studies reporting fatigue-related declines in MS patients' cognitive performance, no differences in performance were found when MS patients were tested during periods of high versus low fatigue. These contrasting results, stemming from differences in experimental design, are discussed in terms of their implications for assessing cognitive function in patients with MS.
