RESUMO
Background: There is limited research examining whether mental health problems increase the risk for future concussions, even though these problems are highly prevalent in college-aged populations-including student-athletes. Purpose/Hypothesis: To examine whether affective disturbance (ie, depressive and anxiety symptoms) at baseline increases the risk for prospective concussion. It was hypothesized that athletes with co-occurring depressive/anxiety symptoms would incur the greatest risk for injury. Methods: A total of 878 collegiate athletes completed baseline neuropsychological testing. Athletes were separated into the following 4 groups based on self-reported anxiety and depressive symptoms at baseline: healthy controls; depressive symptoms alone; anxiety symptoms alone; and co-occurring depressive and anxiety symptoms. Of the 878 athletes, 88 sustained future concussions. Logistic regression was conducted with prospective concussion (yes/no) as the outcome and the affective group as the predictor. Sport was included as a covariate. Results: After controlling for sport, athletes in the co-occurring depressive/anxiety symptoms group were more than twice as likely to be diagnosed with a future concussion compared with healthy controls (odds ratio, 2.72 [95% CI, 1.33-5.57]; P = .01). The co-occurring depressive/anxiety symptoms group also showed an increased risk for prospective concussion compared with the depressive symptoms alone and anxiety symptoms alone groups, respectively. However, the results were not statistically significant. Athletes in the depressive symptoms alone and anxiety symptoms alone groups did not show a significantly increased risk for prospective concussion compared with healthy controls. Conclusion: Athletes with co-occurring depressive/anxiety symptoms at baseline showed a notably increased risk of being diagnosed with a future concussion, even after controlling for sport. This suggests that co-occurring depressive/anxiety symptoms infer a unique risk that is associated with a greater susceptibility to concussion diagnosis.
RESUMO
OBJECTIVE: Little is known about the relationship between neuropsychological test performance, cognitive symptom reporting, and depressive symptoms after sport-related concussion. Accordingly, this cross-sectional study examined these relationships in collegiate athletes. It was hypothesized that depressive symptoms would moderate and mediate the relationship between performance-based and self-reported cognitive functioning after concussion. METHODS: After sustaining a sport-related concussion, 110 collegiate athletes completed a neuropsychological battery, the Post-Concussion Symptoms Scale, and the Beck Depression Inventory-Fast Screen. Neuropsychological test performance, depressive symptoms, and their interactions were entered into distinct hierarchical linear regression analyses with self-reported cognition as the dependent variable to assess moderation. Mediation was analyzed using the PROCESS macro with 5000 bootstrap samples and a 95% confidence interval. RESULTS: There was a significant interaction between the mean memory composite and depressive symptoms when predicting cognitive symptom reporting, p = 0.047. Simple effects tests revealed that for athletes who had a lower memory composite score, an increase in depressive symptoms led to an increase in self-reported cognitive dysfunction, p < 0.001, ηp2 = 0.11. Depressive symptoms partially mediated the relationship between the memory composite and cognitive symptom reporting, indirect effect = -0.26, 95%CI[-0.58,0.001], but this relationship was not found for any other neurocognitive domain. CONCLUSIONS: For tests of memory, depressive symptoms moderated and partially mediated the relationship between performance-based and self-reported cognitive functioning after sport-related concussion. Athletes reporting high depressive symptoms and cognitive dysfunction may need more comprehensive evaluations to inform return-to-play decisions, and depression could be a treatment target for athletes who report high levels of cognitive dysfunction after concussion.
RESUMO
OBJECTIVE: The present study examined physical activity as a possible moderator in the relationship between pain and depressive symptoms among persons with multiple sclerosis (PwMS). METHOD: Fifty-three PwMS completed a comprehensive neuropsychological test battery and psychosocial questionnaires. Pain was operationalized as a composite of measures from the Brief Pain Inventory. Metabolic equivalents (METs) of energy expended during self-reported vigorous activity (VA), moderate activity (MA), and walking, as well as global physical activity which combined the three, were derived from the International Physical Activity Questionnaire-Short Form. Self-reported physical activity was measured using the Cognitive Health Questionnaire Exercise Scale. Regressions on depressive symptoms (Beck Depression Inventory-Fast Screen) examining both conceptualizations of physical activity, pain, and their interactions were explored. RESULTS: Regression analyses revealed that interactions between pain and each measure of global physical activity were significant (p = .01). Simple effects tests revealed that pain only influenced depressive symptoms in PwMS with low global physical activity METs (p < .001) and low overall self-reported physical activity (p < .001). The separate interactions between pain and METs during self-reported VA, MA, and walking on depressive symptoms were not significant. CONCLUSION: We found that global physical activity moderated the relationship between pain and depressive symptoms in MS. Specifically, pain influenced depressive symptoms in PwMS who engaged in less overall physical activity. These results highlight the importance of screening PwMS for pain and suggest that behavioral interventions aimed at increasing overall lifestyle physical activity may be useful in improving depressive outcomes in PwMS with pain.

OBJECTIVE: The primary aim of this paper is to accelerate the number of randomized experimental studies of the reliability and validity in-home tele-neuropsychological testing (tele-np-t). METHOD: We conducted a critical review of the tele-neuropsychology literature. We discuss this research in the context of the United States' public and private healthcare payer systems, including the Centers for Medicare & Medicaid Services (CMS) and Current Procedural Terminology (CPT) coding system's telehealth lists, and existing disparities in healthcare access. RESULTS: The number of tele-np publications has been stagnant since the onset of the COVID-19 pandemic. There are less published experimental studies of tele-neuropsychology (tele-np), and particularly in-home tele-np-t, than other tele-np publications. There is strong foundational evidence of the acceptability, feasibility, and reliability of tele-np-t, but relatively few studies of the reliability and validity of in-home tele-np-t using randomization methodology. CONCLUSIONS: More studies of the reliability and validity of in-home tele-np-t using randomization methodology are necessary to support inclusion of tele-np-t codes on the CMS and CPT telehealth lists, and subsequently, the integration and delivery of in-home tele-np-t services across providers and institutions. These actions are needed to maintain equitable reimbursement of in-home tele-np-t services and address the widespread disparities in healthcare access.

OBJECTIVE: The primary aim of this paper is to review evidence and clinical implications related to lifestyle activities associated with promoting brain and cognitive health. Our review targets four key lifestyle factors: physical activity and exercise, social engagement, cognitively stimulating activity, and consuming Mediterranean-style diets. METHOD: We conducted a critical review of the lifestyle factor literature in the four domains listed earlier. We contextualize this literature review by translating findings, when possible, into evidence-based recommendations to consider when providing neuropsychological services. RESULTS: There is significant current evidence supporting the role of physical activity and exercise, social engagement, cognitively stimulating activity, and consuming Mediterranean-style diets on positive brain and cognitive health outcomes. While some null findings are present in all four areas reviewed, the weight of the evidence supports the notion that engaging in these activities may promote brain and cognitive functioning. CONCLUSIONS: Clinical neuropsychologists can have confidence in recommending engagement in physical activity, social activity, and cognitively stimulating activity, and adhering to a Mediterranean-style diet to promote brain and cognitive health. We discuss limitations in existing lifestyle factor research and future directions to enhance the existing evidence base, including additional research with historically underrepresented groups and individuals with neurological conditions.

IMPORTANCE: This study provides information to clinicians about how persons with MS coped in both positive and negative ways during a potentially traumatic experience (the coronavirus disease 2019 [COVID-19] pandemic), which will help clinicians to provide better services to this population in the face of stressful events. OBJECTIVE: To describe both positive and negative outcomes among persons with multiple sclerosis (MS) and to examine whether resilience and social support were related to positive and negative outcomes during the peak of the pandemic. DESIGN: An online survey administered during the COVID-19 pandemic. PARTICIPANTS: Participants were 74 individuals with MS and 104 healthy controls (HCs) recruited through social media and community support groups. OUTCOMES AND MEASURES: The survey included questionnaires that assessed both positive and negative responses to the pandemic, including benefit finding, loneliness, and distress. Resilience and social support were also assessed. RESULTS: Differences were noted between persons with MS and HCs on negative but not positive outcomes. Better social support and resilience were related to positive outcomes. CONCLUSIONS AND RELEVANCE: Both persons with MS and HCs were similar in benefit finding and stress management. However, negative outcomes were worse in the MS group. Our findings shed light on the importance of individuals with MS adopting a positive outlook to help during times of adversity. What This Article Adds: Among persons with disabilities such as multiple sclerosis, finding benefits during stressful times can be a potential coping mechanism. Furthermore, resilience and social support should be taken into account to moderate the effects of adverse events.

BACKGROUND: Depression is three to four times more prevalent in patients with neurological and inflammatory disorders than in the general population. For example, in patients with multiple sclerosis, the 12-month prevalence of major depressive disorder is around 25% and it is associated with a lower quality of life, faster disease progression, and higher morbidity and mortality. Despite its clinical relevance, there are few treatment options for depression associated with multiple sclerosis and confirmatory trials are scarce. We aimed to evaluate the safety and efficacy of a multiple sclerosis-specific, internet-based cognitive behavioural therapy (iCBT) programme for the treatment of depressive symptoms associated with the disease. METHODS: This parallel-group, randomised, controlled, phase 3 trial of an iCBT programme to reduce depressive symptoms in patients with multiple sclerosis was carried out at five academic centres with large outpatient care units in Germany and the USA. Patients with a neurologist-confirmed diagnosis of multiple sclerosis and depressive symptoms were randomly assigned (1:1:1; automated assignment, concealed allocation, no stratification, no blocking) to receive treatment as usual plus one of two versions of the iCBT programme Amiria (stand-alone or therapist-guided) or to a control condition, in which participants received treatment as usual and were offered access to the iCBT programme after 6 months. Masking of participants to group assignment between active treatment and control was not possible, although raters were masked to group assignment. The predefined primary endpoint, which was analysed in the intention-to-treat population, was severity of depressive symptoms as measured by the Beck Depression Inventory-II (BDI-II) at week 12 after randomisation. This trial is registered at ClinicalTrials.gov, NCT02740361, and is complete. FINDINGS: Between May 3, 2017, and Nov 4, 2020, we screened 485 patients for eligibility. 279 participants were enrolled, of whom 101 were allocated to receive stand-alone iCBT, 85 to receive guided iCBT, and 93 to the control condition. The dropout rate at week 12 was 18% (50 participants). Both versions of the iCBT programme significantly reduced depressive symptoms compared with the control group (BDI-II between-group mean differences: control vs stand-alone iCBT 6·32 points [95% CI 3·37-9·27], p<0·0001, effect size d=0·97 [95% CI 0·64-1·30]; control vs guided iCBT 5·80 points [2·71-8·88], p<0·0001, effect size d=0·96 [0·62-1·30]). Clinically relevant worsening of depressive symptoms was observed in three participants in the control group, one in the stand-alone iCBT group, and none in the guided iCBT group. No occurrences of suicidality were observed during the trial and there were no deaths. INTERPRETATION: This trial provides evidence for the safety and efficacy of a multiple sclerosis-specific iCBT tool to reduce depressive symptoms in patients with the disease. This remote-access, scalable intervention increases the therapeutic options in this patient group and could help to overcome treatment barriers. FUNDING: National Multiple Sclerosis Society (USA).

To investigate cognitive reserve as a possible moderator in the relationship between fatigue and depressive symptoms in persons with multiple sclerosis (PwMS). Fifty-three PwMS (37 female; mean age, 52.66; mean education, 14.81) completed comprehensive neuropsychological testing and psychosocial questionnaires assessing the perceived effects of fatigue (Fatigue Impact Scale) and depressive symptoms (Beck Depression Inventory-Fast Screen). Cognitive reserve (CR) was operationalized as Fixed CR and Malleable CR. Fixed CR was quantified as the standardized mean of years of education and a vocabulary-based estimate of premorbid intelligence. Malleable CR was quantified as the standardized mean of cognitive exertion, exercise, and socializing items from the Cognitive Health Questionnaire. Regressions on depressive symptoms examining fatigue, both conceptualizations of CR, and their interactions were explored. A Bonferroni correction was used; results were considered significant at an alpha level of p < .01. The interactions between fatigue and both conceptualizations of CR were significant, p = .005 (Fixed CR); p = .004 (Malleable CR). Simple effects tests revealed that fatigue only predicted depressive symptoms in PwMS with low Fixed CR or low Malleable CR (p's < .001), and not in those with high Fixed or high Malleable CR (p > .01). Cognitive reserve moderated the relationship between fatigue and depressive symptoms in PwMS. Specifically, fatigue does not appear to influence depression in PwMS with high cognitive reserve. Having higher cognitive reserve (either Fixed or Malleable) may reduce the likelihood that fatigue will lead to depressive symptoms in MS.

OBJECTIVE: Research on the neurocognitive effects of comorbid mood/anxiety disturbance in college athletes is limited. Previous research found that athletes with comorbid depression/anxiety performed worse on measures of attention/processing speed (A/PS) at baseline compared to healthy controls. However, this work solely examined mean performance. The current study expands upon this work by examining intraindividual variability (IIV) in relation to affective disturbance. METHOD: 835 (M = 624, F = 211) collegiate athletes completed baseline neuropsychological testing. Athletes were separated into four groups (Healthy Mood [n = 582], Depression Alone [n = 137], Anxiety Alone [n = 54], and Co-Occurring Depression/Anxiety [n = 62]) based on self-reported anxiety and depression. IIV was examined globally and within composites of A/PS and memory via intraindividual standard deviation, with higher scores indicating greater variability. RESULTS: Linear regression results revealed that the Co-Occurring Depression/Anxiety group exhibited greater variability within the memory composite compared to the Healthy Mood group, as well as the Depression Alone and Anxiety Alone groups. The Depression Alone and Anxiety Alone groups did not differ from the Healthy Mood group on memory IIV. None of the groups differed on A/PS or global IIV. CONCLUSIONS: Athletes with co-occurring depression/anxiety demonstrated greater variability in performance on memory tasks. Greater dispersion is predictive of greater cognitive decline following concussion; therefore, it is important that neuropsychological performance is interpreted beyond measures of central tendency. These findings also highlight the importance of having baseline data available for athletes with affective disturbance, as these factors may influence performance, place athlete at risk for poorer outcomes, and skew future post-concussion comparisons.

OBJECTIVE: Persons with multiple sclerosis (PwMS) are at increased risk for cognitive dysfunction. Considering the impact and potential ramifications of cognitive dysfunction, it is important that cognition is routinely assessed in PwMS. Thus, it is also important to identify a screener that is accurate and sensitive to MS-related cognitive difficulties, which can inform decisions for more resource-intensive neuropsychological testing. However, research focused on available self-report screeners has been mixed, such as with the Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNQ). This study aims to clarify the relationship between subjective and objective assessment of cognitive functioning in MS by examining domain-specific performance and intraindividual variability (IIV). METHODS: 87 PwMS (F = 65, M = 22) completed a comprehensive neuropsychological battery which included self- and informant-report measures of neurocognitive functioning. Scores were examined in relation to mean performance on five domains of cognitive functioning and two measures of IIV. RESULTS: The MSNQ-Self was inversely associated with executive function, verbal memory, and visual memory; it was not associated with IIV. The MSNQ-Informant was inversely associated with executive function and verbal memory, and positively associated with one measure of IIV. The MSNQ-Self showed a correlation of moderate effect size with depression (r = .39) while the MSNQ-Informant did not. CONCLUSIONS: Results suggest that the MSNQ-Self and MSNQ-Informant show similar utility. Our findings also suggest that domains of executive function and memory may be most salient, thus more reflected in subjective reports of cognitive functioning. Future work should further examine the impact of mood disturbance with cognitive performance and IIV.

CONTEXT: Poor sleep is common in collegiate student-athletes and is associated with heterogeneous self-reported complaints at baseline. However, the long-term implications of poor sleep at baseline have been less well studied. OBJECTIVE: To examine the implications of insufficient sleep at baseline, as well as factors such as symptom reporting and neurocognitive performance at baseline associated with insufficient sleep, for the risk of sport-related concussion (SRC). DESIGN: Cross-sectional study. SETTING: Undergraduate institution. PATIENTS OR OTHER PARTICIPANTS: Student-athletes (N = 614) were divided into 2 groups based on the hours slept the night before baseline testing: sufficient (>7.07 hours) or insufficient (≤5.78 hours) sleepers. Athletes who went on to sustain an SRC during their athletic careers at our university were identified. MAIN OUTCOME MEASURE(S): Four symptom clusters (cognitive, physical, affective, and sleep) and headache were examined as self-reported outcomes. Four neurocognitive outcome measures were explored: mean composite of memory, mean composite of attention/processing speed, memory intraindividual variability (IIV), and attention/processing speed IIV. RESULTS: Insufficient sleepers at baseline were nearly twice as likely (15.69%) as sufficient sleepers (8.79%) to go on to sustain an SRC. Insufficient sleepers at baseline, whether or not they went on to sustain an SRC, reported a higher number of baseline symptoms than did sufficient sleepers. When compared with either insufficient sleepers at baseline who did not go on to incur an SRC or with sufficient sleepers who did go on to sustain an SRC, the insufficient sleep group that went on to incur an SRC performed worse at baseline on mean attention/processing speed. CONCLUSIONS: The combination of insufficient sleep and worse attention/processing speed performance at baseline may increase the risk of sustaining a future SRC.

OBJECTIVE: To examine the relationship between sleep disturbance and functional outcomes following a concussion. Also, to explore athlete and injury-related variables that may be related to risk factors for poor sleep following concussion. METHOD: 124 collegiate athletes completed a neuropsychological evaluation within 14 days of sustaining a sport-related concussion (SRC). Athletes were categorized as sleep disturbed (n = 52) or not sleep disturbed (n = 72). Outcome variables included symptom reports, cognitive performance (mean performance and variability), and mood (depression). Injury characteristics and athlete characteristics explored were loss of consciousness (LOC) associated with the injury, whether the athlete was immediately removed from play, and history of prior concussions. RESULTS: Sleep disturbed athletes reported more symptoms, F(4, 119) = 7.82, p < 0.001, Æ2 = 0.21, were more likely to be symptomatic at the time of testing, χ2(1, N = 124) = 19.79, p < 0.001, φ = 0.40, and were marginally more likely to experience clinically significant depression, χ2(1, N = 120) = 3.03, p = 0.08, φ = 0.16, than not sleep disturbed athletes. There were no cognitive differences between the groups, p > 0.05. A greater proportion of sleep disturbed athletes experienced LOC (30%) compared to not sleep disturbed athletes (13%), χ2(1, N = 118) = 4.99, p = 0.03, φ = -0.21. CONCLUSION: Sleep disturbances following SRC are associated with a broad range of self-reported symptoms. LOC may be associated with an increased risk of developing sleep disturbances; alternatively, sleep disturbances may increase the risk of LOC following concussion.

Although several single-nucleotide polymorphisms have been associated with cognitive functioning in a variety of healthy and clinical samples, the influence of gene × gene interactions on cognition is poorly understood. The purpose of this study was to examine interactive relationships between apolipoprotein E (APOE) and brain-derived neurotrophic factor (BDNF) polymorphisms on cognitive functioning in a sample of healthy adolescent athletes. Participants of this cross-sectional study included 78 student-athletes (52.6% male; age: M = 13.31, SD = 1.23). Athletes completed the Immediate Post-Concussion and Cognitive Testing (ImPACT) computerized battery at baseline. APOE and BDNF genotypes were determined with buccal samples (APOE ε4+: n = 26; APOE ε4-: n = 52; BDNF Met+: n = 23; BDNF Met-: n = 55). Two-way analyses of variance (ANOVAs) were used to evaluate the associations among APOE (ε4+ vs. ε4-) and BDNF (Met+ vs. Met-) genotypes and the ImPACT cognitive composites and two-factor model. No main effects were observed for either APOE or BDNF genotypes across the cognitive outcomes. However, there was a significant APOE × BDNF genotype interaction for the verbal (p=.009, ηp2=.091) and visual (p = .012, ηp2=.082) memory composites and the memory factor (p = .001, ηp2=.133), such that ε4+/Met+ carriers demonstrated poorer performance relative to other allele combinations. No significant interactions were observed for the visual motor speed (p = .263, ηp2=.017) or reaction time (p = .825, ηp2=.001) composites or the speed factor (p = .205, ηp2=.022). Our findings suggest an important relationship between APOE and BDNF genotypes on verbal and visual memory performance in healthy adolescent athletes. Clinicians may use this information to offer individualized concussion management based on individual athlete characteristics related to genetics and cognition.

BACKGROUND: Self- and informant-report measures are often useful in predicting objective cognitive performance; however, the relationship between these reports and mood, anxiety, and fatigue requires further examination. Additionally, it remains unclear as to how these factors might be associated with objective neurocognitive performance. METHODS: Eighty-six persons with multiple sclerosis (PwMS; F = 65, M = 21) completed a comprehensive neuropsychological battery that included objective neurocognitive measures, subjective reports of neurocognitive function with the Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNQ) Self-Report (MSNQ-S) and Informant-Report (MSNQ-I), and self-report measures of anxiety, depression, and fatigue. Hierarchical linear regressions were conducted with depression, anxiety, the interaction between depression and anxiety, cognitive fatigue, and physical fatigue as predictors. Outcome variables included the MSNQ-S, MSNQ-I, each of five neurocognitive composites, and global intraindividual variability (IIV). RESULTS: Although greater cognitive fatigue was associated with greater reported cognitive dysfunction, it was not associated with objective neurocognitive impairment. Greater depression predicted poorer performance on measures of processing speed and verbal memory, though the effects became non-significant once accounting for anxiety. The interaction between depression and anxiety predicted greater neurocognitive IIV; those with high levels of depression and anxiety demonstrated greater dispersion of scores. CONCLUSIONS: Cognitive fatigue may skew one's perception of their cognition, though it is not associated with objective impairment. However, co-occurring depression and anxiety were associated with greater variability which is a marker of poorer neurocognitive integrity. Our findings highlight the importance of accounting for depression, anxiety, and cognitive fatigue in PwMS, given that they are all potentially modifiable factors.

OBJECTIVE: Depressive disorder occurs in up to 50% of persons with Multiple Sclerosis (PwMS). Accurate assessment of depression in MS is essential in clinical settings because depressive symptomatology can affect the clinical course of the disease. METHODS: We translated, adapted, and tested the Spanish version of the Chicago Multiscale Depression Inventory (CMDI), a specific test to assess depression in neurological disorders. We compare our results with those obtained with previous versions of the questionnaire (English and Italian). Finally, we also analyze the relationship between the results obtained on the CMDI and demographic, clinical, and cognitive variables. RESULTS: The results obtained with the Spanish version of the CMDI were similar to those observed in previous published versions. We also observed higher depression scores in PwMS (especially in progressive forms) compared with healthy controls. Moreover, depression symptomatology was related to higher disability and fatigue and worse cognitive performance in PwMS. CONCLUSIONS: The results support the validity of the CDMI in the Spanish population, as well as the association between depression and other characteristic symptoms of MS. These findings also emphasize the importance of good assessment and multidisciplinary treatment of depression in PwMS.

Persons with multiple sclerosis (PwMS) have been considered at high risk for vaccination and/or acquisition of COVID-19 related to their reduced immune systems and daily regimen of immune suppressing therapy. Substantiated and unsubstantiated reports on these unknown circumstances increased anxiety and depression. Low-dose naltrexone (LDN) is a potentially effective off-label therapy shown to be effective at controlling fatigue for several autoimmune disorders including MS. This study utilized a small population of PwMS from central Pennsylvania in order to determine whether LDN therapy altered their perceived anxiety or depression during the early months of COVID-19. Utilizing mailed surveys, self-reported anxiety and depression scores were found to be significantly lower for PwMS who were prescribed LDN either alone or as an adjuvant to a standard disease modifying therapy (DMT) in comparison to those on oral disease-modifying therapies (DMTs). The data suggest that the non-toxic, inexpensive biotherapeutic may be beneficial in lessening anxiety.

The purpose of this exploratory study was to examine interactive relationships between a common brain-derived neurotrophic factor (BDNF) polymorphism (Val66Met) and biological sex on cognitive functioning in a sample of healthy adolescent athletes. Participants included 82 student athletes (age: M = 12.85 years, SD = 1.13) who were involved in a clinically-based sports-concussion management program. Athletes completed the ImPACT computerized battery at baseline and provided buccal samples for determination of their BDNF genotype. Two-way ANOVAs were used to evaluate the effect of BDNF genotype (Met+ vs. Met-) and sex (male vs. female) on cognitive functioning (subgroup n's: Female/Met+ = 12, Female/Met- = 26, Male/Met+ = 12, Male/Met- = 32). ANOVAs revealed non-significant main effects for both BDNF genotype and sex across all four cognitive composites. However, there was a significant BDNF genotype by sex interaction for the visual-motor speed composite (p = .015; ηp2 = .073), such that female Met carriers demonstrated better performance than male Met carriers. In contrast, no differences were found on visual-motor speed performance between females and males without a Met allele. Although these results will need to be replicated using larger samples, our preliminary findings lend support to the view that the Met allele may be somewhat neuroprotective in healthy adolescent females.
RESUMO
OBJECTIVE: The goal of this study was to determine the impact of the relationship between cognitive reserve and coping strategy on quality of life (QoL) outcomes in persons with MS (PwMS) across multiple domains. METHODS: We examined the effect of the interactions between coping style and cognitive reserve on QoL and disease burden in 97 persons with MS (PwMS). Coping strategy, either active or avoidant, was measured using the COPE inventory. We defined cognitive reserve as a composite measure of years of education and scores on the Shipley-2 Vocabulary subtest. QoL and disease burden were assessed using the Functional Assessment of MS (FAMS) scale and the Expanded Disability Status Scale, respectively. We examined both the FAMS individual subscales and the overall QoL score. RESULTS: For those with higher cognitive reserve, greater avoidant coping was associated with lower QoL for the thinking and fatigue subscale (p < 0.001) and poorer overall QoL (p = 0.03); greater active coping was associated with poorer QoL for mobility (p = 0.001). However, these associations did not hold for those with lower cognitive reserve. Furthermore, there were no associations between coping strategy and cognitive reserve with disease burden. CONCLUSIONS: This study extends previous findings by demonstrating that avoidant coping, rather than active coping, is associated with poorer thinking and fatigue and overall QoL only for PwMS with greater cognitive reserve. Counseling PwMS on the impact of coping strategies on QoL outcomes, especially for those with greater cognitive reserve, may improve quality of life outcomes in this population.

OBJECTIVE: The present study examined coping style as a possible moderator in the relationship between pain and depression in persons with multiple sclerosis (PwMS). METHODS: Fifty-four PwMS completed a comprehensive neuropsychological test battery and psychosocial questionnaires that assessed physical, cognitive, and emotional functioning. Using four pain indices (i.e., average pain, current pain, pain intensity, and pain interference) from the Brief Pain Inventory (BPI), an overall pain index was created to capture a more comprehensive index of individuals' overall pain intensity and interference. The COPE questionnaire was used to derive three coping indices: active coping, avoidant coping, and a composite cope index that accounts for the relative contributions of both active and avoidant coping. The Beck Depression Inventory-Fast Screen (BDI-FS) was used to measure depressive symptomatology. A series of hierarchical linear regressions were conducted with depressive symptoms as the outcome variable. RESULTS: Regression analyses revealed that the interactions between overall pain and each conceptualization of coping were significant (p = .001-.003). Simple effects tests revealed that overall pain only predicted depressive symptoms in PwMS with low active coping (p < .001), high avoidant coping (p < .001), and less adaptive coping via the composite coping index (p < .001). CONCLUSION: We found that pain predicted depressive symptoms in PwMS who utilized more avoidant and less active coping strategies. Interventions aimed to improve coping style may be effective in enhancing the ability to manage pain and, subsequently, improve depression outcomes in MS.

OBJECTIVES: The current study explored how affective disturbances, particularly concomitant anxiety and depressive symptoms, impact baseline symptom self-reporting on the Post-Concussion Symptoms Scale (PCSS) in college athletes. METHODS: Athletes were separated into four groups (Healthy Control (HC) (n = 581), Depression Only (n = 136), Anxiety Only (n = 54), Concomitant Depression/Anxiety (n = 62)) based on their anxiety and depression scores. Groups were compared on Total PCSS Score as well as 5 PCSS Symptom Cluster scores (Cognitive, Physical, Affective, Sleep, and Headache). RESULTS: The three affective groups reported significantly greater symptomatology than HCs, with the Concomitant group showing the highest symptomatology scores across all clusters. The depressive symptoms only group also reported significantly elevated symptomatology, compared to HCs, on every symptom cluster except headache. The anxiety symptoms only group differed from HCs on only the cognitive symptoms cluster. Additionally, the Concomitant group reported significantly increased PCSS symptomatology, in terms of total scores and all 5 symptom clusters, compared to the depressive symptoms only and anxiety symptoms only groups. CONCLUSIONS: Our findings suggest that athletes experiencing concomitant depressive/anxiety symptoms report significantly greater levels of symptomatology across all 5 PCSS symptom clusters compared to HCs. Further, results suggest that athletes experiencing concomitant affective disturbance tend to report greater symptomatology than those with only one affective disturbance. These findings are important because, despite the absence of concussion, the concomitant group demonstrated significantly elevated symptomatology at baseline. Thus, future comparisons with post-concussion data should account for this increased symptomatology, as test results may be skewed by affective disturbances at baseline.
