Abstract Objective: Findings on the relationship of psychiatric symptoms with performance-based and self-reported cognitive function post-stroke are inconclusive. We aimed to (1) study the relation of depression and anxiety to performance-based cognitive function and (2) explore a broader spectrum of psychiatric symptoms and their association with performance-based versus self-reported cognitive function. Method: Individuals with supratentorial ischemic stroke performed neuropsychological examination 3 months after stroke. For primary analyses, composite scores for memory and attention/executive function were calculated based on selected neuropsychological tests, and the Hospital Anxiety and Depression Scale (HADS) was used. Psychiatric symptoms and self-reported cognitive function for secondary aims were assessed using the Symptom-Checklist-90 – Revised (SCL-90-R). Results: In a sample of 86 patients [mean (M) age: 64.6 ± 9.2; Mini-Mental State Examination (MMSE), 3–7 days post-stroke: M = 28.4 ± 1.7; National Institutes of Health Stroke Scale (NIHSS) after 3 months: M = 0.7 ± 1.6] depressive symptoms (HADS) were associated with poorer memory performance after controlling for age, sex, and education (p ≤ .01). In a subsample (n = 41; Age: M = 65.7 ± 8.1; MMSE: M = 28.4 ± 1.8; NIHSS: M = 1.0 ± 1.9), symptoms of phobic anxiety (SCL-90-R) were associated with poorer performance-based memory and attention/executive function, and symptoms of anxiety (SCL-90-R) with lower attention/executive function. Higher levels of self-reported cognitive difficulties were associated with higher scores in all psychiatric domains (p ≤ .05). Conclusion: Even in relatively well-functioning stroke patients, depressive symptoms are associated with poorer memory. The results also suggest that various psychiatric symptoms are more related to self-reported rather than to performance-based cognitive function. Screening for self-reported cognitive difficulties may not only help to identify patients with cognitive impairment, but also those who need psychological treatment.

AbstractAlthough the obesity paradox is an important modifiable factor in cardiovascular diseases, little research has been conducted to determine how it affects post-stroke cognitive function. We aimed to investigate the association between body mass index (BMI) and domain-specific cognitive outcomes, focusing on the subdivision of each frontal domain function in post-ischemic stroke survivors. A total of 335 ischemic stroke patients were included in the study after completion of the Korean-Mini Mental Status Examination (K-MMSE) and the vascular cognitive impairment harmonization standards neuropsychological protocol at 3 months after stroke. Frontal lobe functions were analyzed using semantic/phonemic fluency, processing speed, and mental set shifting. Our study participants were categorized into four groups according to BMI quartiles. The z-scores of K-MMSE at 3 months differed significantly between the groups after adjustment for initial stroke severity (p = 0.014). Global cognitive function in stroke survivors in the Q1 (the lowest quartile) BMI group was significantly lower than those in Q2 and Q4 (the highest quartile) BMI groups (K-MMSE z-scores, Q1: − 2.10 ± 3.40 vs. Q2: 0.71 ± 1.95 and Q4: − 1.21 ± 1.65). Controlled oral word association test findings indicated that phonemic and semantic word fluency was lower in Q4 BMI group participants than in Q2 BMI group participants (p = 0.016 and p = 0.023 respectively). BMI might differentially affect cognitive domains after ischemic stroke. Although being underweight may negatively affect global cognition post-stroke, obesity could induce frontal lobe dysfunctions, specifically phonemic and semantic word fluency.

   ASSOCIATION BETWEEN ALTERED HS-CRP LEVELS AND  COGNITIVE FUNCTION OF ISCHEMIC STROKE PATIENTSABSTRACTIntroduction: The incidence of cognitive impairment in acute ischemic stroke patients is increasing. The mechanism of the inflammatory effect, such as  elevated hs-CRP level, a  non-specific inflammatory marker  sensitive to chronic inflammation due to hypoperfusion as well other vascular risk, is thought to have an effect on cognitive function.Aims: To determine the relationship of cognitive function changes in acute phase of ischemic stroke with hs-CRP level changes on day 3 and day 7 after onset.Methods: This was a cross sectional study of 31 first-timer ischemic stroke patients who met inclusion and exclusion criteria. The level of hs-CRP was checked on the 3rd day and 7th day after onset, while MoCA-Ina was assessed on the 7th day after onset. Cognitive disturbance was considered if MoCA <26. Analyses was done using SPSS 2.0Results: The average onset of day 3 Hs-CRP concentration was 0.66 (0.12-16.67)mg/dl and the onset of day 7 was 5.455 (0.14-17.34)mg/dl. The mean change of hs-CRP level between 3 day and 7 day after onset was -0,16 (-3.32-4.95). There was a significant correlation between elevated hs-CRP levels on day 3 and day 7 after onset with cognitive function of acute ischemic stroke patients.Discussion: There was a significant correlation between elevated hs-CRP levels on day 3 and day 7 after onset with cognitive function of acute ischemic stroke patients.Keyword: Acute ischemic stroke, hs-CRP, MoCA-Ina scoresABSTRAKPendahuluan: Insidens penurunan fungsi kognitif pada pasien stroke iskemik akut semakin meningkat.

Background: Silent brain infarctions (SBI) are common findings in advanced age, but their relationship to dementia is still uncertain.Aim: The present study was designed to evaluate whether SBI predict the development of dementia after first clinical ischemic stroke.Methods: We blindly studied admission CT scans of 102 consecutive nondemented patients presenting with ischemic stroke that clinically was their first stroke episode. SBI were defined as CT evidence of infarcts not compatible with the acute event. The patients were subsequently followed for their mental state for 2 years. Survival analysis, wherein onset of dementia was the end point, was performed on the total sample population and conducted separately on those with and without SBI at admission.Results: Dementia developed in 33 patients (32.3%), including 17 of the 37 (45.9%) with SBI and 16 of the 65 (24.6%) without SBI. Thus, dementia was strong related to SBI.Conclusion: Elderly people with silent brain infarcts and stroke have an increased risk of dementia and a steeper decline in cognitive function than those without such lesions.

Daily rhythms of behavior and neurophysiology are integral to the circadian clocks of all animals. Examples of circadian clock regulation in the human brain include daily rhythms in sleep-wake, cognitive function, olfactory sensitivity, and risk for ischemic stroke, all of which overlap with symptoms displayed by many COVID-19 patients. Motivated by the relatively unexplored, yet pervasive, overlap between circadian functions and COVID-19 neurological symptoms, this perspective piece uses daily variations in the sense of smell and the timing of sleep and wakefulness as illustrative examples. We propose that time-stamping clinical data and testing may expand and refine diagnosis and treatment of COVID-19.

Abstract Background: Little is known about the effect of osteoporosis at the acute and recovery phase of stroke on cognitive function. We evaluated the effect of osteoporosis on cognitive function in patients with ischemic stroke aged >50 years.Methods: We retrospectively examined consecutive patients with acute stroke hospitalized between 2016 and 2018. Osteoporosis was defined as a T score of <-2.5 for the femoral neck or lumbar spine bone mineral density. The primary outcome was cognitive impairment measured by the Korean Mini-Mental State Examination in the acute phase and recovery phase of ischemic stroke. The association between osteoporosis and the severity of cognitive impairment was investigated using a multivariate analysis.Results: Of the 260 included subjects (107 men and 153 women), 70 (26.9%) had osteoporosis. Cognitive impairment was more severe in the osteoporosis group than in the non-osteoporosis group (30.5% versus 47.1%, p=0.001). After recovery phase of stroke, the proportion of patients with cognitive impairment remained higher in the osteoporosis group. The multivariate analysis revealed a correlation between a low femoral neck bone mineral density and severe cognitive impairment in the acute and recovery phases of stroke (adjusted odds ratio [OR] 3.66, 95% confidence interval [CI] 1.05-12.79 in the acute phase and adjusted OR 11.17, 95% CI 1.12-110.98 in the recovery phase), whereas lumbar spine osteoporosis was not associated with cognitive impairment.Conclusions: Low bone mineral density is associated with poor cognitive function in patients with acute stroke. Early bone mineral density assessments during acute stroke, particularly at the femoral neck, may be a useful marker of cognitive function.
