Cognitive dysfunction (CD) is a common, impairing symptom experienced by persons with fibromyalgia (FM). This study explored how individuals with FM describe their experience of CD in an online peer support environment. Posts referencing cognitive symptoms were extracted from two Facebook FM peer support groups at two timepoints. Using inductive Thematic Analysis, key discussion themes were identified and compared across groups and time. Four themes represented the way members described their cognitive experiences in FM: understanding and describing CD experiences, distrust of cognitive abilities, choosing between pain and medication side effects, and misunderstanding and judgement from others. Two themes represented the impact of CD on members' lives: impaired social interaction and loss of identity. Group members described broad impairments in daily functioning that significantly and negatively impacted their quality of life, indicating CD symptoms may play a more prominent role in the FM experience than previously understood. An infographic is included to aid patient education and help facilitate patient-provider discussions of CD symptoms.

BACKGROUND AND OBJECTIVES
Apathy strongly affects function in Alzheimer's disease and frontotemporal dementia, however its effect on function in Lewy Body Disease (LBD) has not been well-described. This study aims to (1) examine the prevalence and persistence of apathy in a large, national cohort of well-characterized patients with LBD, and (2) estimate the effect of apathy on function over time.
METHODS
Study included 676 participants with mild cognitive impairment (MCI) or dementia in the National Alzheimer's Coordinating Center Uniform Data Set. Participants were followed for an average of 3.4 ± 1.7 years and consistently had a primary diagnosis of LBD. Apathy was defined by clinician judgment, categorized into four mutually exclusive profiles: (1) never apathetic across all visits, (2) at least one but <50% of visits with apathy (), (3) ≥50% but not all visits with apathy (), and (4) across all visits. Dementia severity was measured by baseline Clinical Dementia Rating score. Parkinsonism was defined by the presence of bradykinesia, resting tremor, rigidity, gait, and postural instability. Functional impairment was assessed using the Functional Assessment Questionnaire (FAQ).
RESULTS
Baseline characteristics of the sample were: average age = 72.9 ± 6.9, years of education = 15.6 ± 3.4, Mini Mental State Exam (MMSE) = 24.4 ± 5.4, Geriatric Depression Scale (GDS) = 3.8 ± 3.2, FAQ = 12.0 ± 9.1. 78.8% were male and 89% were non-Hispanic white. Prevalence of apathy increased from 54.4% at baseline to 65.5% in year 4. 77% of participants had apathy at some point during follow-up. Independent of cognitive status and parkinsonian features, FAQ was significantly higher in participants with intermittent/persistent and always apathetic than never apathetic. Annual rate of decline in FAQ was faster in participants who were always apathetic than never apathy.
DISCUSSION
In this large national longitudinal cohort of LBD patients with cognitive impairment, apathy was strongly associated with greater functional impairment at baseline and faster rate of decline over time. The magnitude of these effects were clinically important and were observed beyond the effects on function from participants' cognitive status and parkinsonism, highlighting the importance of specifically assessing for apathy in LBD.

The detrimental effects of sleep loss on overall decision-making have been well described. Due to the complex nature of decisions, there remains a need for studies to identify specific mechanisms of decision-making vulnerable to sleep loss. Bayesian perspectives of decision-making posit judgement formation during decision-making occurs via a process of integrating knowledge gleaned from past experiences (priors) with new information from current observations (likelihoods). We investigated the effects of sleep loss on the ability to integrate multiple sources of information during decision-making by reporting results from two experiments: the first implementing both sleep restriction (SR) and total sleep deprivation (TSD) protocols, and the second implementing an SR protocol. In both experiments, participants were administered the Bayes Decisions Task on which optimal performance requires the integration of Bayesian prior and likelihood information. Participants in Experiment 1 showed reduced reliance on both information sources after SR, while no significant change was observed after TSD. Participants in Experiment 2 showed reduced reliance on likelihood after SR, especially during morning testing sessions. No accuracy-related impairments resulting from SR and TSD were observed in both experiments. Our findings show SR affects decision-making through altering the way individuals integrate available sources of information. Additionally, the ability to integrate information during SR may be influenced by time of day. Broadly, our findings carry implications for working professionals who are required to make high-stakes decisions on the job, yet consistently receive insufficient sleep due to work schedule demands.

The pathophysiology of mild cognitive impairment in Parkinson's disease (PD-MCI) is still not fully elucidated. It has been shown in a few studies in the literature that volume loss in the occipital, parietal and frontal cortices and atrophy in the hippocampus of PD-MCI patients can occur in the early stages of PD. The aim of this study was to evaluate the relationship between gray and white matter volumes and different neuropsychological tests and volumetric magnetic resonance imaging parameters in patients with mild cognitive impairment in Parkinson's disease (PD-MCI). Twenty-six PD-MCI and twenty-six healthy elderly (HC) were included in this study. We found that Mini Mental State Examination, Trail Making Test Part A, Clock Drawing Test, Benton Line Judgment Orientation Test and pentagon figure-copying scores were impaired in PD-MCI patients due to the decrease in brain volumes. Our study revealed that among PD-MCI patients, there was a more noticeable decline in White matter volume (WMV) based on volumetric Magnetic Resonance Imaging (MRI) compared to the localized loss of GMV. We think that these abnormal neuropsychological tests in PD-MCI patients can be used as pretests in the evaluation of the stage of transition to dementia.

BACKGROUND
Amyotrophic lateral sclerosis (ALS) is characterized by a rapid disease course, with disease severity being associated with declining health-related quality of life (HRQoL) in persons living with ALS (pALS). The main objective of this study was to assess the impact of disease progression on HRQoL across King's, Milano-Torino Staging (MiToS), and physician-judgement clinical staging. Additionally, we evaluated the impact of the disease on the HRQoL of care partners (cALS).
METHODS
Data were sourced from the Adelphi ALS Disease Specific Programme (DSP)™, a cross-sectional survey of neurologists, pALS and cALS presenting in a real-world clinical setting between July 2020 and March 2021 in Europe and the United States.
RESULTS
Neurologists (n = 142) provided data for 880 pALS. There were significant negative correlations between all three clinical staging systems and EuroQol (European Quality of Life) Five Dimension Five Level Scale (EQ-5D-5L) utility scores and visual analogue scale (VAS) ratings. Although not all differences were significant, 5-item Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ-5) scores showed a stepwise increase in HRQoL impairment at each stage of the disease regardless of the staging system. At later stages, high levels of fatigue and substantial activity impairment were reported. As pALS disease states progressed, cALS also experienced a decline in HRQoL and increased burden.
CONCLUSIONS
Across outcomes, pALS and cALS generally reported worse outcomes at later stages of the disease, highlighting an unmet need in this population for strategies to maximise QoL despite disease progression. Recognition and treatment of symptoms such as pain and fatigue may lead to improved outcomes for pALS and cALS.

Review
This comprehensive review article explores the intricate mechanisms at work and possible remedies for the connection between sleep issues and cardiovascular health. Sleep disorders, which include conditions like insomnia and sleep apnea, are drawing increasing amounts of attention due to their serious detrimental consequences on cardiovascular health. This article carefully examines the body of existing evidence to explain the intricate mechanisms that connect sleep disruptions to cardiovascular issues. Mechanisms include inflammation, disruption of the autonomic nervous system, endothelial dysfunction, and aberrant metabolic processes all have an impact on these pathways. The study also looks at a variety of existing and novel therapeutic modalities that aim to minimize the detrimental effects of sleep disruptions on cardiovascular health. This includes evaluating the effectiveness of lifestyle changes, pharmaceutical interventions, and behavioural therapy for enhancing sleep quality and hence preserving cardiovascular health. By synthesising and presenting the most recent study data, this article offers valuable insights into the complex relationships between sleep patterns, cardiovascular function, and potential therapeutics. These results provide a solid foundation for guiding future research endeavours and clinical judgements. Pharmacotherapy is a possibility for momentary relief. Cardiovascular illness has been linked to the sensorimotor problem known as restless legs syndrome (RLS), which causes a strong impulse to move the legs. Sleep disruption caused by RLS-related leg movements leads to sympathetic activation, elevated blood pressure, impaired vascular function, and potential iron deficiency. Treating the underlying iron deficiency, when present, and medications targeting dopamine receptors or regulating calcium channels are the primary interventions for RLS. In conclusion, sleep disorders significantly impact cardiovascular health through multiple mechanisms. Early detection, accurate diagnosis, and appropriate interventions are crucial for mitigating associated cardiovascular risks. Multidisciplinary approaches including lifestyle modifications, behavioral interventions, and targeted pharmacotherapy have shown promise in improving sleep quality and cardiovascular outcomes. Further research is needed to enhance our understanding of the complex interplay between sleep disorders and cardiovascular health, leading to the development of more effective interventions and improved patient outcomes.

BACKGROUND
Although rarely framed as enacted stigma, adults with Tourette syndrome (ATS) have long suffered from discrimination associated with their tic symptoms. Given the high stress levels of enacted stigma that ATS experience, it is expected that their tic symptoms are profoundly impacted. However, the evidence linking enacted stigma to ATS's tic symptoms remains limited.
METHODS
This study used a secondary data-analysis approach to reanalyze the data from the follow-up phase of a multi-centered, randomized controlled trial in which a behavioral intervention was tested for its efficacy in managing tic symptoms. This study first conducted psychometric testing on a list of 16 enacted stigma events across five life stages and identified the underlying factor structure. The Yale Global Tic Severity Scale (YGTSS) was used to assess severity and impairment of current tic symptoms, whereas the Clinical Global Impression of Severity scale (CGI) was used to obtain the gestalt of clinical judgment on tic severity. A series of multivariate linear models were then fitted to test the relationships between different types of lifetime enacted stigma and current tic symptoms.
RESULTS
The analytic sample included 73 young ATS (average age of 23.2 [standard deviation = 2.5] years). The factor analysis identified three types of enacted stigmas: "traumatic events," "confrontations," and "subtle mistreatments." In multivariate models, traumatic events significantly associated with YGTSS-severity, whereas subtle mistreatments provided additional explanations for CGI.
CONCLUSIONS
Enacted stigma may play important roles in shaping ATS's current tics symptom severity and, therefore, should be carefully considered in future intervention development.

BACKGROUND
Two thirds of Out-of-Hospital Cardiac Arrests (OHCAs) occur at the patient's home ('at-home-CA'), where bystander CPR (B-CPR) rates are significantly lower than in public locations. Knowledge about the circumstances of this specific setting has mainly been limited to quantitative data. To develop a more conceptual understanding of the circumstances and dynamics of 'at-home CA', we conducted a qualitative interview study.
METHODS
Twenty-one semi-structured in-depth interviews were performed with laypersons who had witnessed 'at-home CA'. The interviews were audio recorded, transcribed, and analysed by qualitative content analysis (QCA). A category system was developed to classify facilitating and impeding factors and to finally derive overarching concepts of 'at-home CA'.
RESULTS
Qualitative Content Analysis yielded 1'347 relevant interview segments. Of these, 398 related to factors facilitating B-CPR, 328 to factors impeding, and 621 were classified neutral. Some of these factors were specific to 'at-home CA'. The privacy context was found to be a particularly supportive factor, as it enhanced the commitment to act and facilitated the detection of symptoms. Impeding factors, aggravated in 'at-home CA' settings, included limited support from other bystanders, acute stress response and impaired situational judgement, as well as physical challenges when positioning the patient. We derived six overarching concepts defining the 'at-home CA' situation: (a) unexpectedness of the event, (b) acute stress response, (c) situational judgement, (d) awareness of the necessity to perform B-CPR, (e) initial position of the patient, (f) automaticity of actions.
CONCLUSION
Integrating these concepts into dispatch protocols and layperson training may improve dispatcher-bystander interaction and the outcomes of 'at-home CA'.

Visuospatial perspective-taking (VPT) is the ability to imagine a scene from a position different from the one used in self-perspective judgments (SPJ). We typically use VPT to understand how others see the environment. VPT requires overcoming the self-perspective, and impairments in this process are implicated in various brain disorders, such as schizophrenia and autism. However, the underlying brain areas of VPT are not well distinguished from SPJ-related ones and from domain-general responses to both perspectives. In addition, hierarchical processing theory suggests that domain-specific processes emerge over time from domain-general ones. It mainly focuses on the sensory system, but outside of it, support for this hypothesis is lacking. Therefore, we aimed to spatiotemporally distinguish brain responses domain-specific to VPT from the specific ones to self-perspective, and domain-general responses to both perspectives. In particular, we intended to test whether VPT- and SPJ specific responses begin later than the general ones. We recorded intracranial EEG data from 30 patients with epilepsy who performed a task requiring laterality judgments during VPT and SPJ, and analyzed the spatiotemporal features of responses in the broad gamma band (50-150 Hz). We found VPT-specific processing in a more extensive brain network than SPJ-specific processing. Their dynamics were similar, but both differed from the general responses, which began earlier and lasted longer. Our results anatomically distinguish VPT-specific from SPJ-specific processing. Furthermore, we temporally differentiate between domain-specific and domain-general processes both inside and outside the sensory system, which serves as a novel example of hierarchical processing.
