Coping style as a protective factor for emotional consequences of structural neuropathology in multiple sclerosis

Depression and anxiety in multiple sclerosis. Review of a fatal combination

Depression and anxiety are the most frequent neuropsychiatric symptoms of multiple sclerosis (MS), an autoimmune-mediated demyelinating neurodegenerative disease. Their prevalence is 25-65% and 20-54%, respectively, often associated with chronic fatigue and cognitive impairment, but usually not correlated with motor and other deficits, suggesting different pathophysiological mechanisms. Both disorders often arise before MS diagnosis, lead to faster disability and impair the quality of life. Risk factors are (young) age, genetic and family history burden. While no specific neuropathological data for depression (and anxiety) in MS are available, modern neuroimaging studies showed bilateral fronto-temporal, subcortical and limbic atrophies, microstructural white matter lesions and disruption of frontoparietal, limbic and neuroendocrine networks. The pathogenesis of both depression and anxiety in MS is related to shared mechanisms including oxidative stress, mitochondrial dysfunction, neuroinflammation and neuroendocrine mechanisms inducing complex functional and structural brain lesions, but they are also influenced by social and other factors. Unfortunately, MS patients with anxiety, major depression or suicidal thoughts are often underassessed and undertreated. Current treatment, in addition to antidepressant therapy include transcranial magnetic stimulation, cognitive, relaxation, dietary and other healthcare measures that must be individualized. The present state-of- the-art review is based on systematic analysis of PubMed, Google Scholar and Cochrane Library until May 2024, with focus on the prevalence, clinical manifestation, neuroimaging data, immune mechanisms and treatment options. Depression and anxiety in MS, like in many other neuroimmune disorders, are related, among others, to multi-regional patterns of cerebral disturbances and complex pathogenic mechanisms that deserve further elucidation as a basis for early diagnosis and adequate management to improve the quality of life in this disabling disease.

Measuring coping in multiple sclerosis: The Coping Index-MS

BACKGROUND

Coping in multiple sclerosis (MS) refers to cognitive and behavioural efforts to manage stresses imposed by the illness. Existing generic and disease-specific coping scales do not meet modern guidelines for scale development and cannot produce interval-level metrics to allow for change scores.

OBJECTIVE

The main aim of this study was to develop a brief patient-reported outcome measure for coping in MS, capable of interval-level measurement.

METHODS

Qualitative work in 43 people with MS leads to a draft scale which was administered to 5747 participants, with longitudinal collection in 2290. A calibration sample of 1000 subjects split into development and validation sets was used to generate three scales consistent with Rasch model expectations.

RESULTS

The total Coping Index-MS (CI-MS-T), CI-MS-Internal (CI-MS-I) and CI-MS-External (CI-MS-E) cover total, internal and externally focused coping. All three scales are capable of interval-level measurement. Trajectory analysis of 9000 questionnaires showed two trajectories in CI-MS-T: Group 1 showed a low level of coping with slight decline over 40 months, while Group 2 had a better and stable level of coping due to improving CI-MS-I which compensated for the deteriorating CI-MS-E over time. CI-MS-T < 30 identified group membership at baseline.

CONCLUSION

The CI-MS-T, CI-MS-I and CI-MS-E, comprising 20 items, provide interval-level measurement and are free-for-use in not-for-profit settings.

Avoidant Coping Is Associated with Quality of Life in Persons with Multiple Sclerosis with High Cognitive Reserve

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 &lt; 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.

Coping with multiple sclerosis: reconciling significant aspects of health-related quality of life

Multiple sclerosis (MS) symptoms and unpredictability can damage patient well-being. This study is aimed to investigate the relation between sociodemographic and clinical characteristics and the use of coping strategies as well as social support on health-related quality of life (HRQOL). We evaluated 314 MS outpatients of Virgen Macarena University Hospital in Sevilla/Spain (mean age 45 years, 67.8% women) twice over an 18-months period by Brief COPE Questionnaire (COPE-28), Multidimensional Scale of Perceived Social Support (MSPSS) and 12-Item Short Form Health Survey (SF-12). Female gender was significantly related to religion (r= 0.175, p< 0.001), self-distraction (r= 0.160, p< 0.001) and self-blame (r= 0.131, p< 0.05). Age correlated positively with religion (r= 0.240, p< 0.001), and self-blame (r= 0.123, p< 0.05). Progressive MS as well as functional impairment (EDSS) showed a positive relation with denial (r= 0.125, p< 0.05; r= 0.150, p< 0.001). Longer duration since diagnosis was related to lower perceived support from family (r= -0.123, p< 0.05). EDSS (β= -0.452, p< 0.001) was the strongest negative predictor of physical HRQOL followed by age (β= -0.123, p< 0.001), whereas family support was a protective factor (β= 0.096, p< 0.001). Denial (β= -0.132, p< 0.05), self-blame (β= -0.156, p< 0.05), female gender (β= -0.115, p< 0.05) and EDSS (β= -0.108, p< 0.05) negatively impacted on mental HRQOL 18 months later, whereas positive reframing (β= 0.142, p< 0.05) was a protective factor. Our study could identify sociodemographic and clinical variables associated with dysfunctional coping strategies, such as self-blame and denial, which specifically predict worse mental HRQOL as opposed to positive reframing. Diminishing dysfunctional coping and supporting cognitive reframing may contribute to improve HRQOL in MS.

Coping strategies used by patients with relapsing multiple sclerosis from Argentina: correlation with quality of life and clinical features

BACKGROUND

Multiple sclerosis (MS) is a chronic neurodegenerative and inflammatory disease. The adaptation to MS depends on the effectiveness of coping, which moderates the process of adaptation and psychological well-being.

OBJECTIVES

We aimed to analyze the coping strategies of an Argentinean population of patients with MS (PwMS) and their association with clinical variables and health-related quality of life (QoL).

METHODS

A nationwide cross-sectional study. Screening instruments: Demographics and clinical data, coping strategies (Brief Coping Orientation to Problems Experienced, [COPE-28]), health-related QoL (MS Impact Scale, [MSIS-29]), Fatigue Severity Scale, and physical disability (self-administrated Expanded Disability Status Scale, [EDSS]).

RESULTS

We included 249 PwMS. Most responders were female (74.7%) with a mean age at survey of 38.6 (±10.7) and had a MS duration of 7.3 years (range: 1-43 years) and a mean EDSS of 1.9 (±1.8). Younger age (r = -0.17), active MS (r = 0.25), higher fatigue (r = 0.22), MSIS-29 total (r = 0.34), MSIS-physical (r = 0.26), MSIS-psychological scores (r = 0.44), higher scores for perception of both severity of MS (r = 0.12) and wheelchair-dependency (r = 0.14) correlated significantly with the use of maladaptive coping strategies. However, active MS (β2.10, p = 0.01), MSIS-psychological score (β0.28, p < 0.0001), high education level (β - 1.15, p = 0.04), and EDSS (β - 0.84, p = 0.0001) were independent predictors of the utilization of maladaptive coping strategies after having applied multivariate analysis via linear regression.

CONCLUSIONS

Maladaptive coping strategies used by PwMS are associated with relevant clinical aspects of the disease and with worse health-related QoL scores.

Investigation of structure-function correlation among the young offspring of patients with bipolar disorder

Bipolar disorder (BD) has been associated with impaired executive functioning and integrity of fronto-limbic white matter tracts. The evaluation of these factors in young offspring of patients with BD (BDoff) as a high-risk group offers an opportunity to investigate factors that could predict vulnerability to the disorder. This study aims to examine the correlation between neurocognition and neuroimaging findings to evaluate the potential for these findings as biomarkers for the early recognition of BD. We enrolled BDoff (n = 16) who were aged between 12 and 18. Participants were assessed using clinical and neurocognitive tests. In addition, structural brain magnetic resonance and diffusion tensor imaging data were obtained. Mean fractional anisotropy (FA) and mean diffusivity (MD) values of the superior longitudinal fasciculus (SLF) and cingulum were extracted and correlations with neuropsychological data were analyzed. FA values in the SLF were negatively correlated with Stroop interference, the Wisconsin Card Sorting Test, and the Trail Making Test (B-A) scores. MD values in the cingulum were inversely correlated with the Child and Youth Resilience Measure and positively correlated with higher scores on the Barratt Impulsiveness Scale-Attentional. These findings provide a link between features of the brain and cognitive dysfunction in BDoff.
