Everyday cognitive failure in patients suffering from neurosarcoidosis

An Unusual Presentation of Neurosarcoidosis in a 64-Year-Old Man: A Case Report

Sarcoidosis is a multisystem granulomatous disorder with an unknown etiology that typically involves the lungs, skin, and lymph nodes, with neurological involvement being relatively rare. We discuss a case of neurosarcoidosis in a 64-year-old man who initially presented with unexplained cognitive impairment, insomnia, hyponatremia, paresthesias, and weight loss and later developed uveitis, diplopia, and dysphagia. Ultimately, findings of hilar and mediastinal lymphadenopathy on chest computed tomography (CT) resulted in bronchoscopy, which led to the diagnosis. This case highlights a rare presentation of sarcoidosis with an unusual constellation of symptoms. We discuss the difficulty involved in diagnosing this disorder as well as its highly variable course.

Investigating the Role of Anger and Cognitive Malfunction in Mental Health: A Cross-Sectional Exploration Paving the Way for a Subsequent Experiment

The functional outcomes associated with subjective well-being (SWB) and the detrimental aspects of psychological distress (PD) make it essential to explore contributing factors. The present study investigated a model about the existing gap in the determining role of trait anger (TA), state anger (SA), cognitive reappraisal (CR), rumination and cognitive failure (CF) as predictors of SWB and PD. The study contributes by exploring the interaction of dispositional, situation factors and emotional regulation strategies in shaping SWB and PD in the Indian Sample. A cross-sectional survey design was employed wherein 600 young adults aged 18-40 (Mage = 22.13, SDage = 4.06) were recruited from Uttar Pradesh, India using a multi-level cluster sampling method. The data were collected using questionnaires in the field setting during August-December 2021. Regression and path analysis revealed that the proposed predictors explained significant variance in SWB and PD, i.e., R2 = 0.24, F (5, 594) = 38.03, p < 0.01, Cohen f2 =0.31 and R2 = 0.35, F (5, 594) = 66.40, p < 0.01, Cohen f2 = 0.53, respectively. The models also fit well with the statistical indices. Except CR, all predictors emerged as significant risk factors. The findings suggest that the interventions to reduce PD and enhance SWB may consider inculcating CR and reducing higher levels of TA, SA, rumination and CF to enhance an individual's adaptive functioning. The findings pave the way for conducting a pre-planned experiment to study the outcomes of various levels of TA in regulating incidental anger (SA) employing CR and rumination.

Longitudinal study of disease severity and external factors in cognitive failure after COVID-19 among Indonesian population

The COVID-19 infection is assumed to induce cognitive failure. Identifying the relationship between COVID-19, the effect of vaccination and medication, and accommodating non-COVID-19 factors to cognitive failure is essential. This study was conducted in Indonesia from September 2021 to January 2023. Demographic information, clinical data, comorbidities, vaccination, and medication during COVID-19 were obtained, as well as a 6-month cognitive assessment with Cognitive Failures Questionnaire/CFQ, Fatigue Severity Score, and Generalized Anxiety Disorder (GAD-7). A Structural Equation Model explains the relationship between potential predictors and cognitive failure. The average score of CFQ after 6 months was 45.6 ± 23.1 out of 100. The severity of the disease, which was associated with vaccination status, age, previous infection, and unit of treatment (p < 0.05), was not related to cognitive failure (p = 0.519), although there is a significant direct impact of worst vaccination status to cognitive failure(p < 0.001). However, age, fatigue, and current anxiety were associated with higher cognitive failure (p < 0.001), although comorbidities and recent headaches were not significant in other models (p > 0.05). This study concludes that cognitive failure after COVID-19 is a multifactorial event and does not solely depend on COVID-19 severity. It is crucial to re-address the factors related to the long-term efficacy of vaccination and medication and focus on non-health factors affecting cognitive failure.Trial Registration: NCT05060562.

Cerebral lesions sites in neurosarcoidosis: a lesion mapping study

BACKGROUND AND PURPOSE

Sarcoidosis is a granulomatous disease of unknown etiology affecting the central nervous system in up to 15% of the patients. Diagnosis of neurosarcoidosis is very challenging due to the heterogeneity of its clinical manifestation. This study intended to evaluate the distribution of cerebral lesion sites and the potential presence of specific lesion clusters in neurosarcoidosis patients using voxel-based lesion symptom mapping (VLSM).

METHODS

Patients with neurosarcoidosis were retrospectively identified and included between 2011 and 2022. Cerebral lesion sites were correlated voxel-wise with presence and absence of neurosarcoidosis using non-parametric permutation test. Multiple sclerosis patients served as controls for the VLSM-analysis.

RESULTS

Thirty-four patients (mean age 52 ± 15 years) of whom 13 were diagnosed with possible, 19 with probable and 2 with confirmed neurosarcoidosis were identified. Lesion overlap of neurosarcoidosis patients demonstrated a distribution of white matter lesions in all brain areas, with a periventricular predilection similar to multiple sclerosis. In contrast to multiple sclerosis controls, no propensity for lesions in proximity of the corpus callosum was observed. Neurosarcoidosis lesions appeared smaller and lesion volume was lower in the neurosarcoidosis cohort. The VLSM analysis showed minor associations between neurosarcoidosis and damaged voxels in the bilateral frontobasal cortex.

CONCLUSIONS

The VLSM analysis yielded significant associations in the bilateral frontal cortex, suggesting that leptomeningeal inflammatory disease with following cortical involvement is a quite specific feature in neurosarcoidosis. Lesion load was lower in neurosarcoidosis than in multiple sclerosis. However, no specific pattern of subcortical white matter lesions in neurosarcoidosis was revealed.

The interplay of physical and cognitive function in rehabilitation of interstitial lung disease patients: a narrative review

Background and Objective

Interstitial lung disease (ILD) encompasses several diverse pulmonary pathologies that result in abnormal diffuse parenchymal changes. When prescribing rehabilitation, several additional factors need to be considered as a result of aging, polypharmacy, and comorbidities manifested in ILD patients. This review aims to discuss issues related to frailty, skeletal muscle and cognitive function that limit physical activities in ILD patients. It will also highlight exercise training and propose complementary strategies for pulmonary rehabilitation.

Methods

A literature search was performed in MEDLINE, CINAHL (inception to October 19th, 2022) using search terms based on concepts of: idiopathic pulmonary fibrosis or interstitial lung disease; frailty; muscular atrophy; skeletal muscle dysfunction; cognitive dysfunction; sleep quality; sleep disorders; anxiety disorders; or depressive disorders. After eligible texts were screened, additional references were included from references cited in the screened articles.

Key Content and Findings

Frailty and skeletal muscle dysfunction are common in ILD. Weight loss, exhaustion, and anti-fibrotic medications can impact frailty, whereas physical inactivity, aging, corticosteroids and hypoxemia can contribute to sarcopenia (loss of muscle mass and function). Frailty is associated with worse clinical status, exercise intolerance, skeletal muscle dysfunction, and decreased quality of life in ILD. Sarcopenia appears to influence wellbeing and can potentially affect overall physical conditioning, cognitive function and the progression of ILD. Optimal assessment tools and effective strategies to prevent and counter frailty and sarcopenia need to be determined in ILD patients. Even though cognitive impairment is evident in ILD, its prevalence and underlying neurobiological model of contributing factors (i.e., inflammation, disease severity, cardiopulmonary status) requires further investigation. How ILD affects cognitive interference, motor control and consequently physical daily activities is not well defined. Strategies such as pulmonary rehabilitation, which primarily focuses on strength and aerobic conditioning have demonstrated improvements in ILD patient outcomes. Future incorporation of interval training and the integration of motor learning could improve transfer of rehabilitation strategies to daily activities.

Conclusions

Numerous underlying etiologies of ILD contribute to frailty, skeletal muscle and cognitive function, but their respective neurobiologic mechanisms require further investigation. Exercise training increases physical measures, but complementary approaches may improve their applicability to improve daily activities.

Association Between Internet Use, Sleep, Cognition and Physical Activity Levels During COVID-19 Lockdown

Purpose

The purpose of this study was to compare internet usage, sleep, cognition and physical activity in college professors and collegiate students during COVID-19 lockdown and to study the association of internet overuse with sleep quality, cognition and physical activity during the COVID-19 lockdown.

Methods

A sample of 125 participants {professors (n = 52) and collegiate students (n = 73)} was recruited from Jamia Hamdard, New Delhi, India. Criteria for inclusion were college professors and collegiate students who uses internet. Both the groups were assessed for internet usage (Internet Addiction Test), sleep quality (Pittsburgh Sleep Quality Index), cognition (Cognitive Failure Questionnaire) and physical activity (Global Physical Activity Questionnaire) via google forms.

Results

There was a significant difference for internet usage (p < 0.05), sleep quality (p = 0.032), cognition (distractibility, p = 0.019) and physical activity in college professors and collegiate students. It has been also reported that there was a significant association of internet usage with sleep quality and cognition and sleep quality with cognition.

Conclusion

Students have more problematic internet usage, bad sleep quality, more cognitive failures and less physical activity than college professors during pandemic lockdown. It has been also observed that problematic internet usage has correlation with sleep quality, cognition and physical activity.

Cognitive Difficulties and Health-Related Quality of Life in Sarcoidosis: An Analysis of the GRADS Cohort

Rationale: Subjective cognitive difficulties are common among sarcoidosis patients; however, previous studies have not modeled the link between cognitive difficulties and health-related quality of life (HRQOL). Objectives: To determine whether cognitive difficulties are associated with HRQOL in sarcoidosis patients after adjusting for demographics, fatigue, and physical disease severity measures. Methods: We performed a secondary analysis of the Genomic Research in Alpha-1 antitrypsin Deficiency and Sarcoidosis (GRADS) study data. We examined the association between self-reported cognitive difficulties (Cognitive Failures Questionnaire (CFQ)) and HRQOL (SF12v2 mental and physical component scores) while adjusting for the demographics, fatigue, and physical disease severity measures (i.e., organ involvement, forced vital capacity). Results: Approximately one-fourth of the patients with sarcoidosis endorsed cognitive difficulties. More frequent cognitive difficulties and more severe fatigue were significantly associated with worse mental HRQOL in the fully adjusted model, while older age was associated with better mental HRQOL. The association between cognitive difficulties and physical HRQOL was not significant in the final model. More severe fatigue, joint involvement, and reduced forced vital capacity (FVC) were associated with worse physical HRQOL, while higher income and higher education were associated with better physical HRQOL. Conclusions: Perceived cognitive difficulties are associated with diminished HRQOL after adjusting for demographics, organ involvement, pulmonary function, and fatigue. The association between cognitive difficulties and reduced HRQOL primarily occurs through the impact on mental components of HRQOL.

Health-Related Quality of Life (HRQoL) in Sarcoidosis: Diagnosis, Management, and Health Outcomes

Health-related quality of life (HRQoL), though rarely considered as a primary endpoint in clinical trials, may be the single outcome reflective of patient priorities when living with a health condition. HRQoL is a multi-dimensional concept that reflects the degree to which a health condition interferes with participation in and fulfillment of important life areas. HRQoL is intended to capture the composite degree of physical, physiologic, psychological, and social impairment resulting from symptom burden, patient-perceived disease severity, and treatment side effects. Diminished HRQoL expectedly correlates to worsening disability and death; but interventions addressing HRQoL are linked to increased survival. Sarcoidosis, being a multi-organ system disease, is associated with a diffuse array of manifestations resulting in multiple symptoms, complications, and medication-related side effects that are linked to reduced HRQoL. Diminished HRQoL in sarcoidosis is related to decreased physical function, pain, significant loss of income, absence from work, and strain on personal relationships. Symptom distress can result clearly from a sarcoidosis manifestation (e.g., ocular pain, breathlessness, cough) but may also be non-specific, such as pain or fatigue. More complex, a single non-specific symptom, e.g., fatigue may be directly sarcoidosis-derived (e.g., inflammatory state, neurologic, hormonal, cardiopulmonary), medication-related (e.g., anemia, sleeplessness, weight gain, sub-clinical infection), or an indirect complication (e.g., sleep apnea, physical deconditioning, depression). Identifying and distinguishing underlying causes of impaired HRQoL provides opportunity for treatment strategies that can greatly impact a patient's function, well-being, and disease outcomes. Herein, we present a reference manual that describes the current state of knowledge in sarcoidosis-related HRQoL and distinguish between diverse causes of symptom distress and other influences on sarcoidosis-related HRQoL. We provide tools to assess, investigate, and diagnose compromised HRQoL and its influencers. Strategies to address modifiable HRQoL factors through palliation of symptoms and methods to improve the sarcoidosis health profile are outlined; as well as a proposed research agenda in sarcoidosis-related HRQoL.

Quality of Life of Couples Living with Sarcoidosis

BACKGROUND

Consequences of sarcoidosis are wide ranging, and the symptom burden has a great impact on patients' quality of life (QoL). However, the QoL of couples living with sarcoidosis has not yet been studied.

OBJECTIVES

Our aim was to assess the QoL of couples living with sarcoidosis and to evaluate whether living with a partner with sarcoidosis influences the partner's QoL. Furthermore, we aimed to assess whether nonspecific symptoms (fatigue, cognitive failure, small fiber neuropathy (SFN)-related symptoms, depressive symptoms, and state/trait anxiety) predict QoL of partners as well as sarcoidosis patients.

METHOD

Sarcoidosis outpatients, recruited at Maastricht University Medical Centre (n = 443), and their partners (n = 208) completed several questionnaires, including the World Health Organization QoL - BREF, Fatigue Assessment Scale, SFN screening list, and cognitive failure questionnaire.

RESULTS

QoL of the partners as well as the sarcoidosis patients was reduced compared with healthy controls, especially regarding the physical health domain. All nonspecific symptoms studied, as well as perceived social support, predicted one or more QoL domains in the sarcoidosis patients, but these factors did not predict the QoL of their partners.

CONCLUSIONS

The QoL of partners of sarcoidosis patients was reduced, although to a lesser extent than that of the patients. Although the nonspecific symptoms and perceived social support were related to the patients' QoL, this was not the case for the partners. In the management of sarcoidosis, it is important to focus not only on the patients but also on their partners.
