Non-amnestic mild cognitive impairment and sleep complaints: a bidirectional relationship?

BACKGROUND: Prior studies documented that several sleep disorders may coexist in patients affected by Mild Cognitive Impairment (MCI) and Alzheimer disease (AD), and have a strong bidirectional relationship with cognitive decline. AIM: To assess the self-reported sleep quality and daytime sleepiness among subjects affected by MCI and AD at early-stage and healthy controls, and to verify if sleep disturbances might be an indicator of specific cognitive deficits. METHODS: 139 patients (102 MCI, 37 AD) underwent comprehensive neuropsychological, functional, and behavioral assessment, which also included Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). 80 healthy elderly subjects were used as controls. MCI patients have been divided into Good Sleepers and Bad Sleepers, depending on their reported sleep quality (PSQI global score ≤5/>5). RESULTS: MCI patients experienced more subjective daytime sleepiness than AD matches. As for the subjective sleep quality among MCI patients, 54% of Bad Sleepers met diagnostic criteria for non-amnestic MCI; vice-versa, 73% of Good Sleepers were diagnosed with amnestic-MCI (p = 0.005), independently of depression and anxiety. CONCLUSIONS: MCI patients complain of daytime sleepiness and dysfunction more than AD patients; among MCI patients, Bad Sleepers appear mainly characterized by a non-amnestic cognitive profile.

Social networks and health status in the elderly: the 'ANZIANI IN-RETE' population-based study.

BACKGROUND: Certain features of the social environment could maintain and even improve not only psychological well-being, but also health and cognition of the elderly. AIMS: We tested the association between social network characteristics and the number of chronic diseases in the elderly. METHODS: A randomized sample of the elderly population of Brescia, Italy, was evaluated (N = 200, age ≥65 years). We performed a comprehensive geriatric assessment, including information on socio-demographic variables (family, friendships, and acquaintance contacts). We measured each person's social network, i.e., degree, efficiency, and variety. RESULTS: The sample included 118 women and 82 men, mean age 77.7 years. The mean number of chronic diseases was 3.5. A higher social network degree, i.e., more social connections, was associated with fewer diseases. We also found that having more contacts with people similar to each other or intense relationships with people who do not know each other were associated with fewer diseases. CONCLUSION: More healthy people tend to share certain characteristics of social networks. Our study indicates that it is important to look at diseases and health as complex phenomena, which requires integrating different levels of analysis.

Dementia after Three Months and One Year from Stroke: New Onset or Previous Cognitive Impairment?

OBJECTIVE: Stroke is an important risk factor for dementia, but the exact mechanism involved in cognitive decline remains unclear. METHODS: Patients were divided into 2 groups: poststroke dementia group (PSD) and poststroke nondementia group (PSND). Variables and neuroradiological hallmarks were compared between 2 groups at 3 months (114 subjects) and 1 year (105 subjects) after stroke. RESULTS: Older age (OR 1.11, 95% CI 1.0-1.2; P < .05), education (OR .6, 95% CI .4-.8; P < .05), prestroke IQCODE (Informant Questionnaire on Cognitive Decline in the Elderly; OR .78, 95% CI .1-5.9; P < .05), premorbid apathy (OR 2.03, 95% CI 1.1-3.7; P < .05), and medial temporal lobe atrophy (MTLA) (OR 6.14, 95% CI 1.4-26.2; P < .05) were independently associated with PSD at 3 months after a cerebrovascular event, whereas at 1-year follow-up older age (OR 1.1, 95% CI 1.0-1.2; P < .05), prestroke IQCODE (OR .05, 95% CI .0-.9; P < .05), MTLA (OR 1.3, 95% CI 1.0-1.6; P < .05), and APACHE II (Acute Physiology and Chronic Health Evaluation; OR .6, 95% CI .4-.9; P < .05) were independently associated with PSD. CONCLUSIONS: Acute cerebrovascular disease could not be the only one mechanism explaining PSD. Neurodegenerative pathology must be taken into account.

Prestroke dementia: characteristics and clinical features in consecutive series of patients.

BACKGROUND/AIM: The prestroke level of cognitive function should be taken into account in order to predict the impact of stroke on the subsequent risk of dementia. The aim of the present study was to investigate the presence and correlates of prestroke dementia (PSD) as well as to identify its clinical features. METHODS: Premorbid clinical and cognitive features of 158 consecutively recruited patients with a diagnosis of acute cerebrovascular pathology were assessed by interviewing the caregivers using multidimensional assessment. Patients were divided into two groups (PSD group and prestroke nondemented group). Baseline cognitive, functional and behavioral variables and neuroradiological hallmarks (medial temporal lobe atrophy, MTLA) were compared between these two groups. RESULTS: In a logistic regression model, older age (OR 1.05), female gender (OR 2.3), Neuropsychiatric Inventory total score (OR 1.1) and MTLA (OR 1.2) were the variables independently associated with PSD. CONCLUSIONS: These findings support the hypothesis that cognitive impairment in patients with stroke may not only be a direct consequence of the acute cerebrovascular event but also a consequence of underlying neurodegenerative pathology.

Diagnosis disclosure and advance care planning in Alzheimer disease: opinions of a sample of Italian citizens.

BACKGROUND AND AIMS: In current Alzheimer disease (AD) research there is growing asymmetry between the modest benefits of the currently available treatments, in contrast to the possibility to diagnose AD early in its natural history. This complex situation brings along a number of important ethical issues about diagnosis disclosure and end-of-life decisions that need to be addressed. The principal aim of the study was to investigate the attitudes towards disclosure of a diagnosis of AD and disposition towards completion of advance care planning, in a sample of Italian citizens. METHODS: A convenience sample of 1,111 Italian citizens recruited from a community hospital in Brescia were interviewed using a structured questionnaire with both yes/no and multiple choice format questions about AD. RESULTS: The majority of the sample (83 %) wanted disclosure for themselves. Women and caregivers were significantly less likely to agree that their hypothetically afflicted relative should be informed of a diagnosis of AD. The majority of the sample (81 %) was in favor of advance care planning completion, most of all younger participants and non-caregivers. Less than a third of the sample (24 %) was aware of the existence a judicially appointed guardian for patients affected by dementia. CONCLUSION: The majority of the participants wanted a potential diagnosis of AD to be disclosed to them and to their relatives if they were to be afflicted. The utility of completion of advance care planning and designation of a judicially appointed guardian is frequently endorsed by the sample.

Can Creativity and Cognitive Reserve Predict Psychological Well-Being in Older Adults? The Role of Divergent Thinking in Healthy Aging.

The maintenance of psychological well-being (PWB) in the older adult population is a pivotal goal for our rapidly aging society. PWB is a multicomponent construct that can be influenced by several factors in the lifespan. The beneficial role of divergent thinking (DT) and cognitive reserve (CR) in sustaining older subjects' PWB has been scarcely investigated so far. The present study aims to investigate the relationships between DT, CR, and PWB in a sample of 121 healthy older adults (61 females; M age: 73.39 ± 6.66 years; M education: 11.33 ± 4.81 years). The results highlight that better DT performance predicts higher CR, which mediates an indirect positive effect of DT on emotional competence, one of the PWB factors. It follows that DT and CR can be considered protective factors in aging, and their effects go beyond cognitive functioning, revealing a positive effect even on some PWB components. The practical implications regarding targeted health interventions for prevention in the older adult population to support well-being and promote healthy aging are discussed.

The impact of cognitive deficit on self-reported car crashes in ultra-octogenarian population: data of an Italian population-based study.

OBJECTIVE: To examine the usefulness of specific neurocognitive tests for predicting the crash involvement in ultra-octogenarian population. METHODS: A total of 800 subjects (mean age 82.4 + 3.1 years) underwent a battery of neuropsychological tests. Global intellectual functioning was assessed using the Mini Mental State Examination, mental flexibility and information processing speed were assessed using the Trail Making Test parts A and B (TMT-A and TMT-B), long-term memory was evaluated with the short story, and visuo-spatial skills were tested with Clock Drawing Test. One year after this evaluation, 343 (43%) participants have been interviewed by a telephone call to know if they were currently driving and if they had a car crash during this period. RESULTS: Two hundred ninety-seven subjects had their driving license renewed and completed the follow-up 1 year after. Data shows that less than 11% of this group had a car crash during the first year of observation (Crash Involved). Older subjects involved in a car crash showed significant worse performances on TMT-B (TMT-B pathological Crash Involved vs. Noncrash Involved 47% vs. 27%; p = 0.02) and on short story (short story pathological Crash Involved vs. Noncrash Involved 19% vs. 5%; p = 0.02). CONCLUSIONS: Trail Making test B and short story have been demonstrated to provide a predictive value of driving performance of older people. Therefore, we suggest that a simple and standardized battery of neuropsychological tests, lasting about 30 min and administered by an experienced staff, is a good diagnostic instrument for risk prevention of driving activity of older drivers.

The Role of Cognition in Divergent Thinking: Implications for Successful Aging.

Promoting active and successful aging has become crucial to improve quality of life in later adulthood and reduce the impact of cognitive decline. Increasing evidence suggested that the ability to think creatively (e.g., via divergent thinking), similar to cognitive reserve, could represent a beneficial factor against the negative effects of aging. However, there is still little evidence investigating the relationships between divergent thinking, cognitive functions, and cognitive reserve in late adulthood. The present study explored these relationships in a sample of 98 individuals ranging from 61 to 88 years old (mean age: 72.44 ± 6.35). Results showed that visual, but not verbal, divergent thinking was affected by aging. Interestingly, visual divergent thinking performance was predicted by both the cognitive component of crystallized intelligence and cognitive reserve. Only the crystallized component of intelligence was found to mediate the aging effect on visual divergent thinking performance. These results suggest that in later adulthood a potential shift strategy to prior knowledge and semantic components over executive and control components of cognition could underlie a preserved ability to think divergently and, plausibly, creatively. Limitations of the study and implications for successful aging are discussed.

Knowledge and attitudes about Alzheimer's disease in the lay public: influence of caregiving experience and other socio-demographic factors in an Italian sample.

BACKGROUND AND AIMS: Despite increasing attention on the knowledge of dementia among patients and family members, little is known about the general public's level of understanding about dementia. The aim of this study was to assess the influence of the caregiving experience, sex and age on the knowledge of AD. METHODS: Eleven hundred and eleven individuals were enrolled. They fulfilled a questionnaire made of 25 questions. The questionnaires were submitted in the waiting rooms of several departments of the Hospital "Spedali Civili di Brescia". The questionnaires assessed several issues, including the general knowledge about Alzheimer's disease, the management and ethical problems. The present study is focused on the analysis of 9 of the 25 questions included in the questionnaire, highlighting aspects about knowledge of symptoms, risk factors, therapies and services. RESULTS: The percentage of correct responses was significantly greater among the caregivers. The group of old respondents gave similar answers, independently of their caregiving status. Women, caregivers or not, are the more knowledgeable group. CONCLUSION: The entire population needs accurate information, but education programs should be specifically tailored for the different sections of the population because they may start with different levels of knowledge.

Aging and Psychological Well-Being: The Possible Role of Inhibition Skills.

(1) Background: Psychological well-being (PWB) is a multidimensional construct which is a key protective factor against chronic diseases in older adults. Numerous psychological and cognitive factors can influence older people's PWB. However, while most studies have explored the effect of general cognition, only a few investigated the role of specific cognitive functions such as the efficiency of executive functions. Thus, the present study aimed to directly explore the relationships between PWB, age, and the core executive functions (namely working memory, flexibility, and inhibition). (2) Methods: A sample of 51 healthy older adults (age range: 60-88) were enrolled and tested both for PWB (by Ryff's psychological well-being scale) and the core executive functions (by the Digit span backward, the Trail Making Test, and the Stroop test). (3) Results: Age and inhibitory skills are negatively correlated to the personal growth subscale of the PWB scale. Moreover, a hierarchical regression analysis showed that inhibition, but not working memory and flexibility, predicted the sense of continued growth and development (personal growth) of older adults, even after controlling for age and educational levels. Limitations and implications for future research and prevention interventions are discussed.

Educational interventions to improve detection and management of cognitive decline in primary care-An Italian multicenter pragmatic study.

Introduction: Timely detection of cognitive decline in primary care is essential to promote an appropriate care pathway and enhance the benefits of interventions. We present the results of a study aimed to evaluate the effectiveness of an educational intervention addressed to Italian family physicians (FPs) to improve timely detection and management of cognitive decline. Materials and methods: We conducted a pre-post study in six Italian health authorities (HAs) involving 254 FPs and 3,736 patients. We measured process and outcome indicators before the intervention (1 January 2014 to 31 December 2016) and after the intervention (1 January 2018 to 31 December 2019). One interactive face-to-face session workshop was delivered by local cognitive disorders and dementia specialists and FP advisors at each HA, in the period September 2017-December 2017. The session focused on key messages of the local Diagnostic and Therapeutic Care Pathway (DTCP) or regional guidelines: (a) the role of the FP for a timely suspicion of cognitive decline is fundamental; (b) when cognitive decline is suspected, the role of the FP is active in the diagnostic work-up; (c) FP's knowledge on pharmacological and non-pharmacological interventions is essential to improve the management of patients with cognitive decline. Results: An overall improvement in diagnostic procedures and management of patients with cognitive decline by FPs after the intervention was observed. The number of visits per year performed by FPs increased, and the time interval between the first FP consultation and the diagnosis was optimized. Neuroleptic use significantly decreased, whereas the use of benzodiazepines remained steadily high. Non-pharmacological interventions, or use of support services, were underrepresented even in the post-intervention. Differences among the participating HAs were identified and discussed. Discussion: Results from this study suggest the success of the educational intervention addressed to FPs in improving early detection and management of cognitive decline, highlighting the importance to continue medical education in this field. At the same time, further initiatives of care pathway dissemination and implementation should promote strategies to enhance interactions between primary and secondary care optimizing the collaboration between FPs and specialists.

Prevalence and demographic features of early-onset neurodegenerative dementia in Brescia County, Italy.

A few epidemiologic studies are available on the prevalence of early-onset Alzheimer disease (AD) and frontotemporal lobar degeneration (FTLD). The aim of this study was to establish in an Italian population, namely in Brescia County, the prevalence of early-onset neurodegenerative dementia, and how it is shared between AD and FTLD. A network among the participating centers has been established for 10 years. A standardized form was sent to be filled in for each patient. The census day was chosen as December 1, 2009. The prevalence of disease was calculated stratifying patients according to sex and diagnosis. On the census day, 175 patients in the whole population aged 45--65 years were enrolled into the study. The resulting overall prevalence of early-onset neurodegenerative dementia was found of 55.1 per 100,000 inhabitants (95%confidence interval, 47.0--63.4). A comparable prevalence between AD and FTLD was reported (25.5 and 29.6 per 100,000 inhabitants, respectively), and no differences in sex distribution were found both in AD and FTLD. The improvement of knowledge on early-onset neurodegenerative dementias allows us to reconsider its epidemiology and to rethink its impact on public polices. This would be crucial for defining the urgency of treatment approaches.

Divergent Thinking Abilities in Frontotemporal Dementia: A Mini-Review.

A large number of studies, including single case and case series studies, have shown that patients with different types of frontotemporal dementia (FTD) are characterized by the emergence of artistic abilities. This led to the hypothesis of enhanced creative thinking skills as a function of these pathological conditions. However, in the last years, it has been argued that these brain pathologies lead only to an augmented "drive to produce" rather than to the emergence of creativity. Moreover, only a few studies analyzed specific creative skills, such as divergent thinking (DT), by standardized tests. This Mini-Review aimed to examine the extent to which DT abilities are preserved in patients affected by FTD. Results showed that DT abilities (both verbal and figural) are altered in different ways according to the specific anatomical and functional changes associated with the diverse forms of FTD. On the one hand, patients affected by the behavioral form of FTD can produce many ideas because of unimpaired access to memory stores (i.e., episodic and semantic), but are not able to recombine flexibly the information to produce original ideas because of damages in the pre-frontal cortex. On the other hand, patients affected by the semantic variant are impaired also in terms of fluency because of the degradation of their semantic memory store. Potential implications, limitations, and future research directions are discussed.

P-Tau as prognostic marker in long term follow up for patients with shunted iNPH.

Objective: Diagnosis of idiopathic Normal Pressure Hydrocephalus (iNPH) relies solely on clinical and radiological criteria while, unlike other neurological diseases, the analysis of cerebrospinal fluid markers is not used in clinical practice. Nevertheless, the overlapping of neurodegenerative diseases affects the long-term shunt efficacy and this occurrence should be detected before surgery. Therefore, we performed this study in order to assess the correlation between pre-surgical levels of CSF Beta Amyloid protein, Total Tau protein and Phospho-Tau protein with long-term clinical outcome. Methods: Between March 2012 and May 2016 we prospective evaluated all patients with iNPH according to guidelines criteria and we analysed CSF concentration of these proteins before and during surgery. Two years after surgery we evaluated iNPH score for all patients, grouping them in shunt responders and non-responders. Results: A total of 117 patients were included: Tap Test non-responders were 58 and at two years we had 35 shunt responders and 15 shunt non-responders. We found a significative difference between shunt-responders and shunt non-responders for pre surgical T-Tau (p: 0.02) and for P-Tau (p: 0.01). All the proteins were significantly associated with clinical outcome after surgery with different cut-off values; in particular, having a 'low' value of T-Tau, P-Tau and Aß1-42 resulted in favourable outcome after surgery. Conclusions: Low level of P-Tau is a useful CSF biochemical prognostic factor for good clinical outcome at least two years after shunt; meanwhile a lower Aß1-42 might suggest that the pathophysiology of iNPH could have something in common with other neurodegenerative diseases of the elderly.

Neuropsychiatric symptoms and syndromes in a large cohort of newly diagnosed, untreated patients with Alzheimer disease.

OBJECTIVES: Neuropsychiatric symptoms are common in patients with Alzheimer disease (AD). Treatment for both AD and psychiatric disturbances may affect the clinical observed pattern and comorbidity. The authors aimed to identify whether particular neuropsychiatric syndromes occur in untreated patients with AD, establish the severity of syndromes, and investigate the relationship between specific neuropsychiatric syndromes and AD disease severity. DESIGN: Cross-sectional, multicenter, clinical study. PARTICIPANTS: A total of 1,015 newly diagnosed, untreated outpatients with AD from five Italian memory clinics were consecutively enrolled in the study from January 2003 to December 2005. MEASUREMENTS: All patients underwent thorough examination by clinical neurologists/geriatricians, including neuropsychiatric symptom evaluation with the Neuropsychiatric Inventory. RESULTS: Factor analysis revealed five distinct neuropsychiatric syndromes: the apathetic syndrome (as unique syndrome) was the most frequent, followed by affective syndrome (anxiety and depression), psychomotor (agitation, irritability, and aberrant motor behavior), psychotic (delusions and hallucinations), and manic (disinhibition and euphoria) syndromes. More than three quarters of patients with AD presented with one or more of the syndromes (N = 790, 77.8%), and more than half exhibited clinically significant severity of symptoms (N = 603, 59.4%). With the exception of the affective one, all syndromes showed an increased occurrence with increasing severity of dementia. CONCLUSIONS: The authors' study supports the use of a syndrome approach for neuropsychiatric evaluation in patients with AD. Individual neuropsychiatric symptoms can be reclassified into five distinct psychiatric syndromes. Clinicians should incorporate a thorough psychiatric and neurologic examination of patients with AD and consider therapeutic strategies that focus on psychiatric syndromes, rather than specific individual symptoms.

Does age at observation time affect the clinical presentation of mild cognitive impairment?

BACKGROUND: To date, there are no published data investigating the role of age in the clinical and neuropsychological presentation of mild cognitive impairment (MCI). The aim of the study was to evaluate whether age at the time of evaluation modulates clinical, functional or cognitive profiles in MCI subjects. METHODS: A total of 167 outpatients with a clinical diagnosis of MCI were consecutively enrolled and entered in the study. Clinical and demographic characteristics were carefully recorded. Each patient underwent a wide neuropsychological standardized assessment. RESULTS: MCI subjects were divided into 3 groups according to their age at observation time: 58 MCI patients were classified as young (≤ 69 years), 89 as old (70-79 years) and 20 as very old (≥ 80 years). The 3 groups did not differ in demographic characteristics, general cognitive functions and memory impairment. Very old MCI subjects showed a significantly greater impairment than younger MCI patients in cognitive domains involving executive functions. In particular, very old MCI patients were more frequently classified as having multiple-domain amnestic MCI. CONCLUSION: Present data highlight that the clinical presentation of MCI is affected by age: at presentation, very old MCI subjects show a worse performance than younger MCI subjects on multiple abilities, particularly on executive functions.

Efficacy of SSRIs on cognition of Alzheimer's disease patients treated with cholinesterase inhibitors.

BACKGROUND: This study examines the joint effect on cognition of selective serotonin re-uptake inhibitors (SSRIs) and cholinesterase inhibitors (AChEIs) in depressed patients affected by Alzheimer's disease (AD) living at home. METHODS: The study was conducted in two different outpatient neurological clinics. 338 patients with probable AD were treated with ChEis (donepezil, rivastigmine and galantamine) as per the clinician's judgment and were observed for nine months. At study entry, participants underwent a multidimensional assessment evaluating cognitive, functional and psychobehavioral domains. All patients were evaluated at baseline, after one (T1), three (T2) and nine months (T3). Patients were grouped in three different categories (patients not depressed and not treated with SSRIs, patients depressed and treated with SSRIs, and patients depressed but not treated with SSRIs). RESULTS: At baseline 182 were diagnosed as not depressed and not treated with SSRIs, 66 as depressed and treated with SSRIs, and 90 as depressed but not treated with SSRIs. The mean change in MMSE score from baseline to nine months showed that depressed patients not treated worsened in comparison with those not depressed and not treated with SSRIs (mean change -0.8 +/- 2.3 vs 0.04 +/- 2.9; p = 0.02) and patients depressed and treated with SSRI (mean change -0.8 +/- 2.3 vs 0.1 +/- 2.5; p = 0.03). CONCLUSIONS: In AD patients treated with AChEIs, SSRIs may exert some degree of protection against the negative effects of depression on cognition.

A Comparison of Divergent Thinking Abilities Between Healthy Elderly Subjects and MCI Patients: Preliminary Findings and Implications.

OBJECTIVE: Divergent thinking (DT) has attracted research interest because of its potential role in early diagnosis and rehabilitation programs for patients affected by neurodegenerative diseases. Recently, DT has received even more attention because of its proven relationship with cognitive reserve (CR) and the possibility of a standardized assessment. However, few studies have investigated this ability in dementia patients, and even less is known about patients affected by Mild Cognitive Impairment (MCI). Thus, this study aims to investigate DT abilities in MCI patients. METHODS: A total of 25 MCI patients and 25 healthy controls subjects (HC; from a random selection of 50) matched for age, gender, and educational level were enrolled. General cognitive functioning was measured by the Montreal Cognitive Assessment (MoCA), while the Abbreviated Torrance Test for Adults (ATTA) was selected to measure DT. RESULTS: MANOVA analysis did not reveal any significant differences in DT abilities between MCI patients and HC except for the figural indicator score. A logistic hierarchical regression analysis revealed that the figural indicator score added an 8% of accuracy in the prediction of the group variable over the general cognition measure (MoCA). CONCLUSION: MCI patients seem to perform significantly worse than HC only in the figural DT score and this evidence has significant practical implications. First, that figural DT seemed to decrease even earlier than verbal DT and could therefore be taken into account for early diagnosis of MCI patients. On the contrary, the sparing of all the other DT skills (such as verbal DT skills, fluency, flexibility, originality, and elaboration) may suggest that, given its relationship with CR, verbal DT could instead be considered a possible target for prevention or early cognitive stimulation interventions.

Clinical characteristics and outcomes of inpatients with neurologic disease and COVID-19 in Brescia, Lombardy, Italy.

OBJECTIVE: To report clinical and laboratory characteristics, treatment, and clinical outcomes of patients admitted for neurologic diseases with and without coronavirus disease 2019 (COVID-19). METHODS: In this retrospective, single-center cohort study, we included all adult inpatients with confirmed COVID-19 admitted to a neuro-COVID unit beginning February 21, 2020, who had been discharged or died by April 5, 2020. Demographic, clinical, treatment, and laboratory data were extracted from medical records and compared (false discovery rate corrected) to those of neurologic patients without COVID-19 admitted in the same period. RESULTS: One hundred seventy-three patients were included in this study, of whom 56 were positive and 117 were negative for COVID-19. Patients with COVID-19 were older (77.0 years, interquartile range [IQR] 67.0-83.8 years vs 70.1 years, IQR 52.9-78.6 years, p = 0.006), had a different distribution regarding admission diagnoses, including cerebrovascular disorders (n = 43, 76.8% vs n = 68, 58.1%), and had a higher quick Sequential Organ Failure Assessment (qSOFA) score on admission (0.9, IQR 0.7-1.1 vs 0.5, IQR 0.4-0.6, p = 0.006). In-hospital mortality rates (n = 21, 37.5% vs n = 5, 4.3%, p < 0.001) and incident delirium (n = 15, 26.8% vs n = 9, 7.7%, p = 0.003) were significantly higher in the COVID-19 group. Patients with COVID-19 and without COVID with stroke had similar baseline characteristics, but patients with COVID-19 had higher modified Rankin Scale scores at discharge (5.0, IQR 2.0-6.0 vs 2.0, IQR 1.0-3.0, p < 0.001), with a significantly lower number of patients with a good outcome (n = 11, 25.6% vs n = 48, 70.6%, p < 0.001). In patients with COVID-19, multivariable regressions showed increasing odds of in-hospital death associated with higher qSOFA scores (odds ratio [OR] 4.47, 95% confidence interval [CI] 1.21-16.5, p = 0.025), lower platelet count (OR 0.98, 95% CI 0.97-0.99, p = 0.005), and higher lactate dehydrogenase (OR 1.01, 95% CI 1.00-1.03, p = 0.009) on admission. CONCLUSIONS: Patients with COVID-19 admitted with neurologic disease, including stroke, have a significantly higher in-hospital mortality and incident delirium and higher disability than patients without COVID-19.
