Processing Speed and Attentional Shift/Mental Flexibility in Patients with Stroke: A Comprehensive Review on the Trail Making Test in Stroke Studies.

The Trail Making Test (TMT) is one of the most commonly administered tests in clinical and research neuropsychological settings. The two parts of the test (part A (TMT-A) and part B (TMT-B)) enable the evaluation of visuoperceptual tracking and processing speed (TMT-A), as well as divided attention, set-shifting and cognitive flexibility (TMT-B). The main cognitive processes that are assessed using TMT, i.e., processing speed, divided attention, and cognitive flexibility, are often affected in patients with stroke. Considering the wide use of TMT in research and clinical settings since its introduction in neuropsychological practice, the purpose of our review was to provide a comprehensive overview of the use of TMT in stroke patients. We present the most representative studies assessing processing speed and attentional shift/mental flexibility in stroke settings using TMT and applying scoring methods relying on conventional TMT scores (e.g., time-to-complete part A and part B), as well as derived measures (e.g., TMT-(B-A) difference score, TMT-(B/A) ratio score, errors in part A and part B). We summarize the cognitive processes commonly associated with TMT performance in stroke patients (e.g., executive functions), lesion characteristics and neuroanatomical underpinning of TMT performance post-stroke, the association between TMT performance and patients' instrumental activities of daily living, motor difficulties, speech difficulties, and mood statue, as well as their driving ability. We also highlight how TMT can serve as an objective marker of post-stroke cognitive recovery following the implementation of interventions. Our comprehensive review underscores that the TMT stands as an invaluable asset in the stroke assessment toolkit, contributing nuanced insights into diverse cognitive, functional, and emotional dimensions. As research progresses, continued exploration of the TMT potential across these domains is encouraged, fostering a deeper comprehension of post-stroke dynamics and enhancing patient-centered care across hospitals, rehabilitation centers, research institutions, and community health settings. Its integration into both research and clinical practice reaffirms TMT status as an indispensable instrument in stroke-related evaluations, enabling holistic insights that extend beyond traditional neurological assessments.

Probiotics' Effects in the Treatment of Anxiety and Depression: A Comprehensive Review of 2014-2023 Clinical Trials.

Changes in the gut microbiome can affect cognitive and psychological functions via the microbiota-gut-brain (MGB) axis. Probiotic supplements are thought to have largely positive effects on mental health when taken in sufficient amounts; however, despite extensive research having been conducted, there is a lack of consistent findings on the effects of probiotics on anxiety and depression and the associated microbiome alterations. The aim of our study is to systematically review the most recent literature of the last 10 years in order to clarify whether probiotics could actually improve depression and anxiety symptoms. Our results indicate that the majority of the most recent literature suggests a beneficial role of probiotics in the treatment of depression and anxiety, despite the existence of a substantial number of less positive findings. Given probiotics' potential to offer novel, personalized treatment options for mood disorders, further, better targeted research in psychiatric populations is needed to address concerns about the exact mechanisms of probiotics, dosing, timing of treatment, and possible differences in outcomes depending on the severity of anxiety and depression.

A Questionnaire-Based Cross-Sectional Study of Insomnia among Middle-Aged Adults from Greece's Northeastern Fringe, Thrace.

Background, aim: Insomnia constitutes a common and very debilitating disorder in modern societies. A better understanding of the etiologies and risk factors, modifiable or not, of insomnia is essential for a swifter diagnosis and a more appropriate treatment, mitigating its toll on individuals and society. To this purpose, the present study assessed the prevalence of insomnia in a randomly-selected adult population and its relation with a diverse range of socio-demographic characteristics and medical conditions. Methods:A sample of 771 participants aged 24 to 89 years (mean age 58±13 years; 42.7% women) was randomly selected from the general population of Thrace, a prefecture in Northeastern Greece with special cultural considerations, using a two-stage stratified sampling scheme. The Greek version of the Athens Insomnia Scale (AIS) was utilized to evaluate the presence of insomnia. Moreover, the Berlin Questionnaire for Obstructive Sleep Apnea and the Epworth Sleepiness Scale for Excessive Daytime Sleepiness were also utilized. Results:A total of 141 study participants (18.3%) were found to suffer from insomnia. Impaired sleep maintenance was reported as the most frequent symptom (62%). The following independent statistically significant risk factors emerged (p-value <0.05): BMI ≥35 (aOR=2.91), divorced or widowed individuals (aOR=2.23), female gender (aOR=1.76), age >70 years (aOR=1.61), snoring (aOR=1.61), midday sleep (aOR=1.58) and presence of chronic disease (aOR=1.55). Conclusion:The prevalence of isomnia in Thrace aligns with similar studies conducted in Greece and internationally. A multitude of socio-demographic characteristics and diseases, especially chronic, predispose to insomnia.

Targeting Neutrophil Extracellular Traps for Stroke Prognosis: A Promising Path.

Stroke has become the first cause of functional disability and one of the leading causes of mortality worldwide. Therefore, it is of crucial importance to develop accurate biomarkers to assess stroke risk and prognosis. Emerging evidence suggests that neutrophil extracellular trap (NET) levels may serve as a valuable biomarker to predict stroke occurrence and functional outcome. NETs are known to create a procoagulant state by serving as a scaffold for tissue factor (TF) and platelets inducing thrombosis by activating coagulation pathways and endothelium. A literature search was conducted in two databases (MEDLINE and Scopus) to trace all relevant studies published between 1 January 2016 and 31 December 2022, addressing the potential utility of NETs as a stroke biomarker. Only full-text articles in English were included. The current review includes thirty-three papers. Elevated NET levels in plasma and thrombi seem to be associated with increased mortality and worse functional outcomes in stroke, with all acute ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage included. Additionally, higher NET levels seem to correlate with worse outcomes after recanalization therapies and are more frequently found in strokes of cardioembolic or cryptogenic origin. Additionally, total neutrophil count in plasma seems also to correlate with stroke severity. Overall, NETs may be a promising predictive tool to assess stroke severity, functional outcome, and response to recanalization therapies.

Investigating the Predictive Value of Thyroid Hormone Levels for Stroke Prognosis.

Given the expansion of life expectancy, the aging of the population, and the anticipated rise in the number of stroke survivors in Europe with severe neurological consequences in the coming decades, stroke is becoming the most prevalent cause of functional disability. Therefore, the prognosis for a stroke must be timely and precise. Two databases (MEDLINE and Scopus) were searched to identify all relevant studies published between 1 January 2005 and 31 December 2022 that investigated the relationship between thyroid hormone levels and acute stroke severity, mortality, and post-hospital prognosis. Only full-text English-language articles were included. This review includes Thirty articles that were traced and incorporated into the present review. Emerging data regarding the potential predictive value of thyroid hormone levels suggests there may be a correlation between low T3 syndrome, subclinical hypothyroidism, and poor stroke outcome, especially in certain age groups. These findings may prove useful for rehabilitation and therapy planning in clinical practice. Serum thyroid hormone concentration measurement is a non-invasive, relatively harmless, and secure screening test that may be useful for this purpose.

Depression and anxiety in caregivers of patients with functional seizures.

OBJECTIVE: Contrary to patients, the psychological impact of functional seizures to caregivers has not been adequately investigated. This study aimed to evaluate the rates and determinants of depression and anxiety in caregivers of patients with functional seizures. METHODS: Patients with functional seizures and their caregivers completed surveys about demographic, disease-related, and psychosocial characteristics. Rates and determinants of depression and anxiety were evaluated using the Beck Depression and Anxiety Inventory scores as dependent variables and patient and caregiver characteristics as independent variables. RESULTS: Twenty-nine patients (76% female, mean age of 37 years) and their caregivers (59% female, mean age of 43 years) were recruited. Symptoms of anxiety and/or depression were present in 96% of patients (96% depression, 92% anxiety) and 59% of caregivers (52% depression, 50% anxiety). Specifically, 31% of caregivers manifested mild depression, 14% moderate depression, and 7% severe depression, whereas 48% were not depressed. Similarly, 14% of caregivers manifested mild anxiety, 29% moderate anxiety, and 7% severe anxiety, whereas 50% were not anxious. Patient and caregiver depression levels strongly correlated (r = .73, p < .0001). The presence of anxiety and depression in the caregiver was associated with male patient gender (p = .02), patient depression level (p = .002), the caregiver being a parent or sibling (p = .02), and caregiver burden (p = .0009). SIGNIFICANCE: Caregivers of patients with functional seizures experience high rates of anxiety and depression, explained by specific demographic and psychosocial factors that could act as intervention targets.

Leukoaraiosis as a Predictor of Depression and Cognitive Impairment among Stroke Survivors: A Systematic Review.

Stroke survivors are at increased risk of developing depression and cognitive decline. Thus, it is crucial for both clinicians and stroke survivors to be provided with timely and accurate prognostication of post-stroke depression (PSD) and post-stroke dementia (PSDem). Several biomarkers regarding stroke patients' propensity to develop PSD and PSDem have been implemented so far, leukoaraiosis (LA) being among them. The purpose of the present study was to review all available work published within the last decade dealing with pre-existing LA as a predictor of depression (PSD) and cognitive dysfunction (cognitive impairment or PSDem) in stroke patients. A literature search of two databases (MEDLINE and Scopus) was conducted to identify all relevant studies published between 1 January 2012 and 25 June 2022 that dealt with the clinical utility of preexisting LA as a prognostic indicator of PSD and PSDem/cognitive impairment. Only full-text articles published in the English language were included. Thirty-four articles were traced and are included in the present review. LA burden, serving as a surrogate marker of "brain frailty" among stroke patients, appears to be able to offer significant information about the possibility of developing PSD or cognitive dysfunction. Determining the extent of pre-existing white matter abnormalities can properly guide decision making in acute stroke settings, as a greater degree of such lesioning is usually coupled with neuropsychiatric aftermaths, such as PSD and PSDem.

Implications of Adverse Outcomes Associated with Antipsychotics in Older Patients with Dementia: A 2011-2022 Update.

Neuropsychiatric symptoms affect most patients with dementia over the course of the disease. They include a wide variety of symptoms from apathy and depression to psychosis, irritability, impulsivity and agitation. These symptoms are associated with significant distress to the patient and caregivers, as well as more rapid progression of dementia, institutionalisation and higher mortality. The first-line management of the neuropsychiatric symptoms of dementia should be non-pharmacological. If medications are required, antipsychotics are commonly chosen. Second-generation antipsychotics such as risperidone, olanzapine, quetiapine and aripiprazole are prescribed more often than first-generation antipsychotics, such as haloperidol. The aim of this review is to provide an update on findings on adverse outcomes and clinical implications of antipsychotic use in dementia. These medications may increase mortality and can be associated with adverse events including pneumonia, cerebrovascular events, parkinsonian symptoms or higher rates of venous thromboembolism. Risks related to antipsychotic use in dementia are moderated by a number of modifiable and non-modifiable factors such as co-prescribing of other medications, medical and psychiatric co-morbidities, and demographics such as age and sex, making individualised treatment decisions challenging. Antipsychotics have further been associated with an increased risk of reliance on long-term care and institutionalisation, and they might not be cost-effective for healthcare systems. Many of these risks can potentially be mitigated by close physical health monitoring of antipsychotic treatment, as well as early withdrawal of pharmacotherapy when clinically possible.

"How Do Greeks Sleep?" A Cross-Sectional Study among Indigenous and Minority Populations.

Objective: To investigate sleep habits and their potential relationship with several sociodemographic, lifestyle and health related characteristics among indigenous and minority populations in Northeastern Greece. Materials and methods: Nine hundred fifty seven adults aged 19 to 86 years were enrolled in this cross-sectional study. Self-reported structured questionnaires were utilized. Results:The reported mean sleep duration on a weekly basis was 6:26±1:10 hours (range, 04:00 to 10:00 hours); sleep duration was 26 min longer on weekends (p < 0.001). In multivariate linear regression analysis, older age (ß=-26.7 min, p=0.010), being divorced or widowed (ß=-29.0 min, p < 0.001), high alcohol (ß=-39.7 min, p < 0.001) or coffee (ß=-36.9 min, p=0.006) consumption, screen exposure before bedtime for 1-2 hours (ß=-18.9 min, p=0.004) or > one hour (ß=-34.4 min, p < 0.001), having a child aged under six years (ß=-62.3 min, p < 0.001), napping for > 30 min during the day (ß=-35.2 min, p < 0.001) and morbidity (ß=-21.5 min, p < 0.001) were independently associated with short sleep duration and lower sleep efficiency. Moreover, a tendency towards short sleep duration was associated with anxiety (ß=-8.8 min, p=0.078) and depression (ß=-12.8 min, p=0.029). Obesity (ß=10.7 min, p=0.047), being a university student (ß=41.0 min, p=0.002), high financial status (ß=16.6 min, p=0.037) and high adherence to Mediterranean diet (ß=15.4 min, p=0.002) were associated with long sleep duration. Conclusion:This study illustrates the association of sleep disturbances with several sociodemographic and health-related factors and dictates conduction of larger scale prospective studies to evaluate causality on the relationship between sleep patterns and lifestyle factors.

NEUROSCIENCE AND ART: LIFE AND TIMES OF YANNOULIS CHALEPAS

The objective of this article is to highlight the bidirectional relationship between neuroscience and art in the life and times of the most preeminent sculptor in modern Greek history, Yannoulis Chalepas. Analysis of biographical sources and testimonies on the life and works of Yannoulis Chalepas was performed. Findings are discussed in relation to the neuropsychiatric maladies that he faced in his lifespan and their impact on his art. Yannoulis Chalepas' life and art are trichotomized in a charismatic, premorbid era (1851-1877), a prolonged, medieval, morbid period (1878-1917), and a transfigurative, post morbid era (1918-1938). The amalgamate of medical evidence suggests that Yannoulis Chalepas suffered from schizophrenia. That was reflected in his art through two distinct periods of artistic productivity and stylistic creativity. The bidirectional relationship between neuroscience and art in the history of humanity is also exemplified in the legacy of Yannoulis Chalepas. The borderland of artistic ingenuity with aberrant behavior, the misconceptions of neurocognitive disorders with psychosis along with their associated social stigma, the effect of artistic expression in the manifestation of psychiatric disease, as well as its healing and often transformative power are concepts that still tantalize equally scientists and artists around the globe.

Exploring the association between sleep insufficiency and self-reported cardiovascular disease among northeastern Greeks.

Objective: To explore the association of sleep characteristics with cardiovascular disease (CVD) using self-reported questionnaires. Material and Methods: 957 adults between 19 and 86 years old were enrolled in this cross-sectional study. The participants were classified into three groups [short (<6h), normal (6-8h), and long (>8h) sleepers] by using multistage stratified cluster sampling. CVD was defined by a positive response to the questions: "Have you been told by a doctor that you have had a heart attack or angina or stroke or have you undergone bypass surgery?". Sleep quality, utilizing Epworth sleepiness scale, Athens insomnia scale, Pittsburgh sleep quality index and Berlin questionnaire, was also examined. Results: Prevalence of CVD was 9.5%. Individuals with CVD exhibited reduced sleep duration by 33 min (p<0.001) and sleep efficiency by 10% (p<0.001). In multivariable logistic regression analysis, adjusting for subjects' sociodemographic, lifestyle habits and health related characteristics, short sleep duration was almost three times more frequent in patients with CVD (aOR=2.86, p<0.001 in the entire sample; aOR=2.68, p=0.019 in women and aOR=2.57, p=0.009 in men). Furthermore, CVD was significantly associated with excessive daytime sleepiness (aOR=2.02, p=0.026), insomnia (aOR=1.93, p=0.010), poor sleep quality (aOR=1.90, p=0.006) and increased risk of obstructive sleep apnea (aOR=2.08, p=0.003). Conclusion: Our study highlights a strong correlation of sleep insufficiency with CVD and promotes early pharmacological or cognitive behavioral interventions in order to protect cardiovascular health.

The Clinical Utility of Leukoaraiosis as a Prognostic Indicator in Ischemic Stroke Patients.

Stroke constitutes a major cause of functional disability with increasing prevalence among adult individuals. Thus, it is of great importance for both clinicians and stroke survivors to be provided with a timely and accurate prognostication of functional outcome. A great number of biomarkers capable of yielding useful information regarding stroke patients' recovery propensity have been evaluated so far with leukoaraiosis being among them. Literature research of two databases (MEDLINE and Scopus) was conducted to identify all relevant studies published between 1 January 2012 and 25 June 2022 that dealt with the clinical utility of a current leukoaraiosis as a prognostic indicator following stroke. Only full-text articles published in English language were included. Forty-nine articles have been traced and are included in the present review. Our findings highlight the prognostic value of leukoaraiosis in an acute stroke setting. The assessment of leukoaraiosis with visual rating scales in CT/MRI imaging appears to be able to reliably provide important insight into the recovery potential of stroke survivors, thus significantly enhancing stroke management. Yielding additional information regarding both short- and long-term functional outcome, motor recovery capacity, hemorrhagic transformation, as well as early neurological deterioration following stroke, leukoaraiosis may serve as a valuable prognostic marker poststroke. Thus, leukoaraiosis represents a powerful prognostic tool, the clinical implementation of which is expected to significantly facilitate the individualized management of stroke patients.

Summarising data and factors associated with COVID-19 related conspiracy theories in the first year of the pandemic: a systematic review and narrative synthesis.

Conspiracy theories can have particularly harmful effects by negatively shaping health-related behaviours. A significant number of COVID-19 specific conspiracy theories emerged in the immediate aftermath of the pandemic outbreak. The aim of this study was to systematically review the literature on conspiracy theories related to COVID-19 during the first year of the pandemic (2020), to identify their prevalence, their determinants and their public health consequences. A comprehensive literature search was carried out in PubMed and PsycINFO to detect all studies examining any conspiracy theory related to COVID-19 between January 1st 2020, and January 10th 2021. Forty-three studies were included with a total of 61,809 participants. Between 0.4 and 82.7% of participants agreed with at least one conspiracy belief. Certain sociodemographic factors (young age, female gender, being non-white, lower socioeconomic status), psychological aspects (pessimism, blaming others, anger) and other qualities (political conservatism, religiosity, mistrust in science and using social media as source of information) were associated with increased acceptance of conspiracy theories. Conspiracy beliefs led to harmful health-related behaviours and posed a serious public health threat. Large-scale collaborations between governments and healthcare organizations are needed to curb the spread of conspiracy theories and their adverse consequences.

The impact of the first UK COVID-19 lockdown on presentations with psychosis to mental health services for older adults: An electronic health records study in South London.

OBJECTIVES: Social distancing restrictions in the COVID-19 pandemic may have had adverse effects on older adults' mental health. Whereby the impact on mood is well-described, less is known about psychotic symptoms. The aim of this study was to compare characteristics associated with psychotic symptoms during the first UK lockdown and a pre-pandemic comparison period. METHODS: In this retrospective observational study we analysed anonymised records from patients referred to mental health services for older adults in South London in the 16-week period of the UK lockdown starting in March 2020, and in the comparable pre-pandemic period in 2019. We used logistic regression models to compare the associations of different patient characteristics with increased odds of presenting with any psychotic symptom (defined as hallucinations and/or delusion), hallucinations, or delusions, during lockdown and the corresponding pre-pandemic period. RESULTS: 1991 referrals were identified. There were fewer referrals during lockdown but a higher proportion of presentations with any psychotic symptom (48.7% vs. 42.8%, p = 0.018), particularly hallucinations (41.0% vs. 27.8%, p < 0.001). Patients of non-White ethnicity (adjusted odds ratio (OR): 1.83; 95% confidence interval (CI): 1.13-2.99) and patients with dementia (adjusted OR: 3.09; 95% CI: 1.91-4.99) were more likely to be referred with psychotic symptoms during lockdown. While a weaker association between dementia and psychotic symptoms was found in the pre-COVID period (adjusted OR: 1.55; 95% CI: 1.19-2.03), interaction terms indicated higher odds of patients of non-White ethnicity or dementia to present with psychosis during the lockdown period. CONCLUSIONS: During lockdown, referrals to mental health services for adults decreased, but contained a higher proportion with psychotic symptoms. The stronger association with psychotic symptoms in non-White ethnic groups and patients with dementia during lockdown suggests that barriers in accessing care might have increased during the COVID-19 pandemic.

Diffusion Tensor Imaging as a Prognostic Tool for Recovery in Acute and Hyperacute Stroke.

Stroke represents a major cause of mortality and long-term disability among adult populations, leaving a devastating socioeconomic impact globally. Clinical manifestation of stroke is characterized by great diversity, ranging from minor disability to considerable neurological impairment interfering with activities of daily living and even death. Prognostic ambiguity has stimulated the interest for implementing stroke recovery biomarkers, including those provided by structural neuroimaging techniques, i.e., diffusion tensor imaging (DTI) and tractography for the study of white matter (WM) integrity. Considering the necessity of prompt and accurate prognosis in stroke survivors along with the potential capacity of DTI as a relevant imaging biomarker, the purpose of our study was to review the pertinent literature published within the last decade regarding DTI as a prognostic tool for recovery in acute and hyperacute stroke. We conducted a thorough literature search in two databases (MEDLINE and Science Direct) in order to trace all relevant studies published between 1 January 2012 and 16 March 2022 using predefined terms as key words. Only full-text human studies published in the English language were included. Forty-four studies were identified and are included in this review. We present main findings and by describing several methodological issues, we highlight shortcomings and gaps in the current literature so that research priorities for future research can be outlined. Our review suggests that DTI can track longitudinal changes and identify prognostic correlates in acute and hyperacute stroke patients.

Gut Microbiome: A Brief Review on Its Role in Schizophrenia and First Episode of Psychosis.

There is a growing body of evidence highlighting the role of gut microbiota as a biological basis of psychiatric disorders. The existing literature suggest that cognitive and emotional activities can be influenced by microbes through the microbiota-gut-brain axis and implies an association between alterations in the gut microbiome and several psychiatric conditions, such as autism, depression, bipolar disorder and psychosis. The aim of this review is to summarise recent findings and provide concise updates on the latest progress of the role of gut microbiota in the development and maintenance of psychiatric symptoms in schizophrenia and the first episode of psychosis. Despite the lack of consistent findings in regard to specific microbiome changes related to psychosis, the emerging literature reports significant differences in the gut microbiome of schizophrenic subjects compared to healthy controls and increasingly outlines the significance of an altered microbiome composition in the pathogenesis, development, symptom severity and prognosis of psychosis. Further human studies are, however, required, which should focus on identifying the drivers of microbiota changes in psychosis and establish the direction of causality between psychosis and microbiome alterations.

Association between sleep insufficiency and dyslipidemia: a cross-sectional study among Greek adults in the primary care setting.

Objective: To investigate the potential association between sleep insufficiency and dyslipidemia (DL) in the primary care setting using self-reported questionnaires. Material and Methods: 957 adults aged between 19 and 86 years old from the rural area of Thrace, Greece were enrolled in this cross-sectional study. Multistage stratifed cluster sampling was used and the subjects were classifed into three groups according to sleep duration [short (<6h), normal (6-8h), and long (>8h) sleep duration]. DL was defined by a positive response to the question "Have you ever been told by a doctor or health professional that your blood cholesterol or triglyceride levels were high?", or if they were currently taking antilipidemic agents. Sleep quality, utilizing Epworth sleepiness scale, Athens insomnia scale, Pittsburgh sleep quality index and Berlin questionnaire, was also examined. Results: DL prevalence was significantly associated with short sleep duration (aOR=2.18, p<0.001) and insomnia (aOR=1.43, p=0.050), while its relation with poor sleep quality (aOR=1.31, p=0.094) and risk for obstructive sleep apnea (aOR=1.32, p=0.097) were of marginal statistical significance. Concerning insomnia subtypes, DL was significantly associated with difficulties maintaining sleep (aOR=2.99, p<0.001) and early morning awakenings (aOR=1.38, p=0.050), but not difficulties initiating sleep (aOR=1.18, p=0.328). Conclusion: This study reveals an association between sleep pathology and DL. Thus, early pharmacological and cognitive or behavioral interventions that improve sleep are deemed necessary in order to decrease DL burden.

Sedation-Associated Medications at Dementia Diagnosis, Their Receptor Activity, and Associations With Adverse Outcomes in a Large Clinical Cohort.

OBJECTIVES: We aimed to investigate whether sedative medications are associated with adverse outcomes in people with dementia, and whether specific characteristics of these medications predict a higher risk of harm. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: 15,210 patients diagnosed with dementia between 2008 and 2017 in South London. METHODS: From recorded medications at dementia diagnosis, we ascertained those with drowsiness listed as a side effect (termed "sedative" hereafter) and subdivided them by frequency and strength of sedation, receptor profile, half-life, and whether they were psychotropics. Multivariable Cox regression models were applied to determine risk of mortality and emergency hospitalization, and generalized estimating equations to investigate cognitive decline. Final models were adjusted for 19 potential confounders, including measures of physical and mental health, functioning, and central anticholinergic burden. RESULTS: At diagnosis, 70.4% of patients with dementia were receiving at least 1 sedative medication. Median survival time was 4.0 years and median time to first hospitalization 1.4 years. After controlling for potential confounders, receipt of any sedative medication at dementia diagnosis was associated with accelerated cognitive decline and a higher hospitalization risk, but only medications with a cautionary warning yielded an increased mortality hazard. Medications acting through γ-aminobutyric acid agonism, psychotropic sedatives, and those with a short half-life were associated with a higher risk of mortality. γ-aminobutyric acid agonists, N-methyl-d-aspartate receptor antagonists, and nonpsychotropic sedatives were associated with an increased hospitalization risk. α1 antagonist, antihistamines, N-methyl-d-aspartate receptor antagonists, psychotropic sedatives, and those with the shortest or longest half-life were associated with accelerated cognitive decline. CONCLUSIONS AND IMPLICATIONS: Receipt of any sedative agent was associated with hospitalization and accelerated cognitive decline. Differences in hazard appear to exist between frequency and strength of sedation, receptor profiles, half-life, and prescribing indication. These differences should be taken into consideration in medication reviews at the time of dementia diagnosis.

Depression and Anxiety in Adult Persons With Epilepsy and Their Caregivers: A Survey-Based Study at a Tertiary Care Center.

ABSTRACT: This study evaluated the rates of depression and anxiety and their determinants in adult persons with epilepsy and their caregivers. Both completed surveys about demographic, disease-related, and psychosocial characteristics. One hundred patients and caregivers participated. A mood disorder was present in 89% of patients and 56% of caregivers. In the univariate analysis, the presence of mood disorder in the patient was associated with being unmarried, unemployed, frequent hospitalizations, side effects from polypharmacy, patient stigma, patient quality of life, caregiver anxiety, and caregiver burden. In the multivariate analysis, medication side effects sustained as an important determinant. In the univariate analysis, the presence of mood disorder in the caregiver was associated with seizure frequency, patient anxiety, patient quality of life, caregiver stigma, and caregiver burden. In the multivariate analysis, patient anxiety level and caregiver burden sustained as important determinants. Adult persons with epilepsy and their caregivers experience high rates of mood disorders, explained by certain clinical factors.
