Abstract
Aim Cerebral infarction, a common type of stroke, results from a sudden interruption of blood flow to the brain, leading to a myriad of challenges and complications for patients. Among these complications, decreased muscle strength is a prominent issue that can have profound implications for patients' overall well-being and functional independence. Decreased muscle strength in cerebral infarction often manifests as weakness, loss of mobility, and impaired ability to perform activities; the psychological impact of these physical limitations can lead to anxiety and depression, further exacerbating the patient's condition. To investigate the effect of progressive rehabilitation nursing on the physical rehabilitation and quality of life of patients with cerebral infarction, to provide valuable insights and guidance for enhancing the functional recovery of individuals affected by cerebral infarction. Design 100 cerebral infarction patients combined with decreased muscle strength admitted to our hospital between October 2019 and October 2020 were randomly selected as the study subjects for prospective analysis. Methods They were divided into a control group (n = 50) and an experimental group (n = 50) using the random number table method. Patients in the control group underwent rehabilitation treatment, while patients in the experimental group underwent progressive rehabilitation nursing intervention guided by quality nursing intervention. The Fugl-Meyer Assessment (FMA) motor function score, National Institute of Health Stroke Scale (NIHSS) neurological function score, Barthel Index (BI), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores, nursing efficiency and the incidence rate of adverse mood after 1, 2 and 3 weeks of nursing were recorded and compared between the two groups. Results The FMA and BI index scores of patients in the experimental group were notably higher than those in the control group, and the comparison was statistically significant (P < .05); The NIHSS, SAS and SDS scores of patients in the experimental group were notably lower than those of the control group, and the results of the comparison were statistically significant (P < .05); The nursing efficiency and nursing satisfaction of patients in the experimental group was remarkably higher, and the results of the comparison were statistically significant (P < .05); The incidence of bad mood in the experimental group was significantly lower than that in the control group after 1, 2 and 3 weeks of nursing, and the incidence rate of adverse mood in the experimental group was improved with time, that is, 1>2>3 weeks in descending order (P < .05). Patient or Public Contribution Progressive rehabilitation nursing not only enhances muscle strength and restores their physical functions to a certain extent while reducing the incidence of adverse reactions and physical function but also mitigates the risk of adverse mood states. Ultimately, it contributes to an improved overall quality of life and psychological well-being of patients affected by cerebral infarction.

Abstract
OBJECTIVE The thalamus is the integrative hub of the brain with reciprocal connections throughout the cortex. This case report describes a right-handed 81-year-old male patient who experienced sudden onset cognitive impairment following a focal left anterior thalamic infarct. METHODS With consent/assent, the patient was seen for a short neuropsychological assessment 6 weeks post stroke. Neuropsychological assessment included review of medical history, collateral intake, the Toronto Cognitive Assessment, Frontal Systems Behavior Scale-Family Rating Form, the Neuropsychiatric Inventory Questionnaire, and piano performance. RESULTS The assessment revealed impaired performance on measures of orientation, memory, executive function, and language, as well as symptoms including hallucinations, apathy, and hypersomnolence, consistent with thalamic dementia. Remarkably, in this context, the patient maintained an ability to play piano and read music. CONCLUSIONS The case has implications for understanding the complex integrative functions of the thalamus, including how profound impairment can simultaneously present with cognitive strengths that may not be captured by performance on neuropsychological testing. This case also suggests that magnetic resonance imaging may be indicated in cases presenting with vascular risk factors and sudden onset cognitive impairment, given that computed tomography may not be sensitive to small subcortical infarcts.

Abstract
BACKGROUND Currently, cerebral infarction (CI) is mainly treated by emergency craniotomy or conservative treatment. However, some studies have questioned the functional recovery of patients after hyperbaric oxygen therapy (HBOT)-specialized care. OBJECTIVE This paper mainly explores the influence of HBOT-specialized care on limb motor function (LMF) and mental state of CI patients with hemiplegia. METHODS The medical records of 113 CI patients with hemiplegia treated in our hospital from March 2020 to March 2022 were collected. Of these, 53 received routine care nursing (conventional group) and 60 cases were given HBOT-specialized care (research group). Patient general data, scores of Fugl-Meyer Assessment (FMA), National Institutes of Health Stroke Scale (NIHSS), Self-rating Anxiety/Depression Scale (SAS/SDS) and Barthel Index (BI), and nursing efficiency were comparatively analyzed. RESULTS The two groups showed comparability in general data. FMA and BI scores were increased in the research group after rehabilitation treatment, higher than the baseline and those of the conventional group, while NIHSS, SAS, and SDS scores were reduced, lower compared with baseline and those of the conventional group. In addition, significantly higher nursing efficiency was determined in the research group. CONCLUSION HBOT-specialized care has beneficial effects on LMF, mental state, negative emotions and self-care ability of CI patients with hemiplegia and can enhance nursing efficacy, which deserves clinical popularization.

Abstract
Despite lacking aphasia seen with left hemisphere (LH) infarcts involving the middle cerebral artery territory, right hemisphere (RH) strokes can result in significant difficulties in affective prosody. These impairments may be more difficult to identify but lead to significant communication problems.We determine if evaluation of singing can accurately identify stroke patients with cortical RH infarcts at risk for prosodic impairment who may benefit from rehabilitation.A prospective cohort of 36 patients evaluated with acute ischemic stroke was recruited. Participants underwent an experimental battery evaluating their singing, prosody comprehension, and prosody production. Singing samples were rated by 2 independent reviewers as subjectively "normal" or "abnormal," and analyzed for properties of the fundamental frequency. Relationships between infarct location, singing, and prosody performance were evaluated using t tests and chi-squared analysis.Eighty percent of participants with LH cortical strokes were unable to successfully complete any of the tasks due to severe aphasia. For the remainder, singing ratings corresponded to stroke location for 68% of patients. RH cortical strokes demonstrated a lower mean fundamental frequency while singing than those with subcortical infarcts (176.8 vs 130.4, P = 0.02). They also made more errors on tasks of prosody comprehension (28.6 vs 16.0, P < 0.001) and production (40.4 vs 18.4, P < 0.001).Patients with RH cortical infarcts are more likely to exhibit impaired prosody comprehension and production and demonstrate the poor variation of tone when singing compared to patients with subcortical infarcts. A simple singing screen is able to successfully identify patients with cortical lesions and potential prosodic deficits.

Abstract
Hippocampal atrophy and pathology are common in ageing-related disorders and associated with cognitive impairment and dementia. We explored whether environmental enrichment (EE) ameliorated the pathological sequelae in the hippocampus subsequent to chronic cerebral hypoperfusion induced by bilateral common carotid artery stenosis (BCAS). Seventy-four male C57BL/6 J mice underwent BCAS or sham surgery. One-week after surgery, mice were exposed to three different degrees of EE; either standard housing conditions (std), limited 3 -h exposure to EE per day (3 h) or full-time exposure to EE (full) for 3 months. Four months after surgery, the hippocampus was examined for the extent of vascular brain injury and neuronal and glial changes. Results showed that long-term BCAS induced strokes, most often in CA1 subfield, reduced 40-50 % CA1 neurons (P < 0.01) and increased microglia/macrophage in CA1-CA3 subfields (P < 0.02). Remarkably, both 3 h and full-time EE regimes attenuated hippocampal neuronal death and repressed recurrent strokes with complete prevention of larger infarcts in mice on full-time EE (P < 0.01). Full-time EE also reduced astrocytic clasmatodendrosis and microglial/macrophage activation in all CA subfields. Our results suggest that exposure to EE differentially reduces long-term hypoperfusive hippocampal damage. The implementation of even limited EE may be beneficial for patients diagnosed with vascular cognitive impairment.

Abstract
Objectives Psychiatric symptoms (PS) can be non-motor features in Parkinson’s disease (PD) which are common even in the prodromal, untreated phase of the disease. Some PS, especially depression and anxiety recently became known predictive markers for PD. Our objective was to explore retrospectively the prevalence of PS before the diagnosis of PD. Methods In the framework of the Hungarian Brain Research Program we created a database from medical and medication reports submitted for reimbursement purposes to the National Health Insurance Fund in Hungary, a country with 10 million inhabitants and a single payer health insurance system. We used record linkage to evaluate the prevalence of PS before the diagnosis of PD and compared that with patients with ischemic cerebrovascular lesion (ICL) in the period between 2004–2016 using ICD-10 codes of G20 for PD, I63-64 for ICL and F00-F99 for PS. We included only those patients who got their PD, ICL and psychiatric diagnosis at least twice. Results There were 79 795 patients with PD and 676 874 patients with ICL. Of the PD patients 16% whereas of those with ischemic cerebrovascular lesion 9.7% had a psychiatric diagnosis before the first appearance of PD or ICL (p<0.001) established in psychiatric care at least twice. The higher rate of PS in PD compared to ICL remained significant after controlling for age and gender in logistic regression analysis. The difference between PD and ICL was significant for Mood disorders (F30-F39), Organic, including symptomatic, mental disorders (F00-F09), Neurotic, stress-related and somatoform disorders (F40-F48) and Schizophrenia, schizotypal and delusional disorders (F20-F29) diagnosis categories (p<0.001, for all). Discussion The higher rate of psychiatric morbidity in the premotor phase of PD may reflect neurotransmitter changes in the early phase of PD.

Abstract
Impaired motor function is a common disabling sequela after stroke. It is closely associated with the patient's quality of life and independence. Neuropsychological dysfunctions also frequently occur in stroke patients. In this paper, we evaluate the relationship between the recovery of motor function and neuropsychological functions, including cognition, language, emotion, behavior, personality, and social interaction, to provide appropriate and effective therapy for stroke patients. Motor function, neuropsychological status, social functioning, as well as emotional aspects such as depression and anxiety symptoms, were initially evaluated one month after cerebral infarction onset. The evaluations were repeated three months after the onset. Motor function was assessed with the Modified Barthel Index. The neuropsychological status was evaluated using the Mini-Mental State Examination, Global Deterioration Scale, digit span test, Korean-Boston Naming Test, Vineland Social Maturity Scale, Neuropsychiatric Inventory, Beck's Depression Inventory, and Beck Anxiety Inventory. In the results, the Modified Barthel Index, Mini-Mental State Examination, Global Deterioration Scale, digit span test, and Vineland Social Maturity Scale were significantly different between the two-time points (P < 0.05). Initial Social Maturity Scale Social Age and Social Maturity Scale Social Quotient categories of the Vineland Social Maturity Scale and Mini-Mental State Examination scores were significantly correlated with Modified Barthel Index improvement (P < 0.05). The amount of change in the Social Maturity Scale Social Age and Social Maturity Scale Social Quotient scores was significantly correlated with Modified Barthel Index improvement (P < 0.05). In multiple linear regression analysis, only the initial Social Maturity Scale Social Quotient score and the amount of score change in Social Maturity Scale Social Quotient showed a significant correlation with Modified Barthel Index improvement (P < 0.05). Social function and interaction are important in motor recovery of ischemic stroke patients.

Abstract
BACKGROUND Age-associated increases in medical complexity, frailty, and cognitive impairment may compromise reliable reporting of medical history. OBJECTIVE To evaluate the influence of increasing age and cognitive impairment on concordance between reported history of stroke and cerebral infarction, and reported history of diabetes and elevated hemoglobinA1c in community-dwelling older adults. METHODS The association between participant-specific factors and accurate reporting of stroke or diabetes was evaluated using multivariable logistic regression in 1,401 participants enrolled in longitudinal studies of memory and aging, including 425 participants with dementia (30.3%). Stroke and diabetes were selected as index variables as gold standard measures of both were obtained in all participants: magnetic resonance neuroimaging for cerebral infarcts and hemoglobinA1c (≥6.5%) for diabetes. RESULTS Concordance between reported history of stroke and imaging-confirmed cerebral infarction was low (sensitivity: 17.4%, 8/46; specificity: 97.9%, 799/816). Small infarcts were strongly associated with inaccurate reporting (OR = 265.8; 95% CI: 86.2, 819.4), suggesting that occult/silent infarcts contributed to discordant reporting. Reporting accuracy was higher concerning diabetes (sensitivity: 83.5%, 147/176; specificity: 96.2%, 1100/1143). A history of hypertension (OR = 2.3; 95% CI: 1.3, 4.2), higher hemoglobinA1c (OR = 1.9; 95% CI: 1.5, 2.4), and hemoglobinA1c compatible with impaired glucose tolerance (OR = 3.1; 95% CI 1.8, 5.3) associated with increased odds of discordant reporting. Cognitive impairment and increased age were not independently associated with reliable reporting. CONCLUSION Factors beyond advancing age and cognitive impairment appear to drive discordance in reported medical history in older participants. Objective testing for cerebral infarcts or diabetes should be performed when relevant to diagnostic or therapeutic decisions in clinical and research settings.

Abstract
Cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL) is a heritable, rare small vessel disease, which is caused by HTRA1 mutations and mostly reported Japanese and Chinese population. CARASIL is an orphan disease, which presents with progressive motor and cognitive impairment, alopecia, and spondylosis. The disease typically starts with lumbago at early twenties. Ischemic strokes start at mid-twenties. Patients have no cardiovascular or any other risk factors. Multiple lacunar infarcts and leukoencephalopathy cause progressive neurologic involvement. Leukoencephalopathy and small vessel disease without any risk factors is a significant finding for the differential diagnosis of HTRA1 gene pathology. This report presents clinical and genetic features of a rare case of typical CARASIL from Turkey who was followed with uncertain diagnoses for years.

Abstract
To evaluate the effectiveness and safety of Salvianolate injection (SI) in the treatment of acute cerebral infarction (ACI).We electronically searched databases including PubMed, The Cochrane Library, EMBASE, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, and WanFang Data to collect randomized controlled trials (RCTs) focused on SI treating ACI up to August 2017. Two reviewers independently screened literatures, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software.A total of 39 RCTs involving 4516 patients were included. The results of meta-analysis showed that compared with the Western medicine (WM) therapies group [experimental group (EG)], the total effective rate of SI + WM [control group (CG)] was higher (relative risk = 1.29, 95% CI: 1.24-1.35, P < .00001) in 21 RCTs; SI could improve movement function evaluation scores, including National Institute of Health Stroke Scale, Barthel Index, activities of daily living (P < .00001). There was no significant difference in modified Rankin Scale scores between the 2 groups (P = .008) EG was better than CG in improving Montreal Cognitive Assessment scores (P = .001) and Mini-Mental State Examination scores (P < .00001). SI could improved not only the hemorheology indexes, including plasma viscosity, whole blood high-shear viscosity, whole blood low-shear viscosity, fibrinogen (P < .00001), but also high-sensitivity C-reactive protein and C-reactive protein. EG could achieve a better effect on improving the neural deficit scores (P < .00001). There was no significant difference about adverse drug reactions/adverse drug events between the EG and CG (P = .73).Salvianolate can promote recovery of the motor and cognitive function of patients with ACI. However, due to the limited quality and quantity of included studies, more high-quality studies are needed to verify the above conclusion.

Abstract
The aim of this study was to investigate post-stroke depression (PSD) and cognitive impairments in patients with different types of cerebral infarction.A total of 110 patients with cerebral infarction treated in our hospital from January 2015 to February 2016 were included in present study. Forty-seven patients were PSD patients and 63 patients were non-PSD patients. The Hamilton Depression Rating Scale (HAMD) and Mini-Mental State Examination (MMSE) were employed to assess depression and cognition of patientsAmong PSD patients, the proportion of patients with partial anterior circulation infarction (PACI, 68.75%) was significantly higher than patients with lacunar circulation infarction (LACI, 29.17%) and posterior circulation infarction (POCI, 26.67%) (P < .05). No significant difference was found in PSD patients with LACI and POCI (P > .05). The MMSE score of patients with PACI (18.05 ± 2.61) was lower than patients with POCI and LACI (P < .05), however, no significant difference was found in patients with LACI and POCI (P > 0.05). The incidences of cognitive impairment in patients with PACI, LACI, and POCI were 12.50%, 14.58%, and 13.33%, respectively. The MMSE score of PSD patients (21.23 ± 2.12) was significantly lower than non-PSD patients (P < .05).Compared with LACI and POCI patients, PACI patients had a higher incidence of PSD and impaired cognitive functions. In addition, affective disorders such as depression may be correlated with cognitive impairment in patients with cerebral infarction.

Abstract
The intent and feelings of the speaker are often conveyed less by what they say than by how they say it, in terms of the affective prosody - modulations in pitch, loudness, rate, and rhythm of the speech to convey emotion. Here we propose a cognitive architecture of the perceptual, cognitive, and motor processes underlying recognition and generation of affective prosody. We developed the architecture on the basis of the computational demands of the task, and obtained evidence for various components by identifying neurologically impaired patients with relatively specific deficits in one component. We report analysis of performance across tasks of recognizing and producing affective prosody by four patients (three with right hemisphere stroke and one with frontotemporal dementia). Their distinct patterns of performance across tasks and quality of their abnormal performance provides preliminary evidence that some of the components of the proposed architecture can be selectively impaired by focal brain damage.

Abstract
Motor rehabilitative training after stroke can improve motor function and promote topographical reorganization of remaining motor cortical movement representations, but this reorganization follows behavioral improvements. A more detailed understanding of the neural bases of rehabilitation efficacy is needed to inform therapeutic efforts to improve it. Using a rat model of upper extremity impairments after ischemic stroke, we examined effects of motor rehabilitative training at the ultrastructural level in peri-infarct motor cortex. Extensive training in a skilled reaching task promoted improved performance and recovery of more normal movements. This was linked with greater axodendritic synapse density and ultrastructural characteristics of enhanced synaptic efficacy that were coordinated with changes in perisynaptic astrocytic processes in the border region between head and forelimb areas of peri-infarct motor cortex. Disrupting synapses and motor maps by infusions of anisomycin (ANI) into anatomically reorganized motor, but not posterior parietal, cortex eliminated behavioral gains from rehabilitative training. In contrast, ANI infusion in the equivalent cortical region of intact animals had no effect on reaching skills. These results suggest that rehabilitative training efficacy for improving manual skills is mediated by synaptic plasticity in a region of motor cortex that, before lesions, is not essential for manual skills, but becomes so as a result of the training. These findings support that experience-driven synaptic structural reorganization underlies functional vicariation in residual motor cortex after motor cortical infarcts.SIGNIFICANCE STATEMENT Stroke is a leading cause of long-term disability. Motor rehabilitation, the main treatment for physical disability, is of variable efficacy. A better understanding of neural mechanisms underlying effective motor rehabilitation would inform strategies for improving it. Here, we reveal synaptic underpinnings of effective motor rehabilitation. Rehabilitative training improved manual skill in the paretic forelimb and induced the formation of special synapse subtypes in coordination with structural changes in astrocytes, a glial cell that influences neural communication. These changes were found in a region that is nonessential for manual skill in intact animals, but came to mediate this skill due to training after stroke. Therefore, motor rehabilitation efficacy depends on synaptic changes that enable remaining brain regions to assume new functions.

Abstract
OBJECTIVE To observe the curative effect of dl-3-n-Butylphthalide (NBP) on patients with acute cerebral infarction (ACI) and its effects on levels of serum vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF). PATIENTS AND METHODS A total of 160 ACI patients treated in our hospital who met the criteria were selected and randomly divided into treatment group (n=80, including 42 males and 38 females) and control group (n=80, including 40 males and 40 females). The control group was treated with routine drug therapy, while the treatment group was treated with butylphthalide on this basis. The curative effect was evaluated using the National Institute of Health Stroke Scale (NIHSS) and the Activity of Daily Life Scale (ADL Scale). The levels of the two factors in serum were measured using enzyme-linked immunosorbent assay (ELISA), and the changes in the levels of the two factors in serum at different time points before and after treatment were compared between the two groups. RESULTS After treatment, the levels of the two factors in serum in both groups were significantly increased compared with those before treatment (p<0.05), and the increase in treatment group was more significant than that in control group (p<0.05). The scores of ADL scale in both groups were significantly increased after treatment compared with those before treatment, and the increase in treatment group was more significant than that in control group (p<0.05). The scores of NIHSS in both groups were significantly decreased compared with those before treatment, and the decrease in treatment group was more significant than that in control group (p<0.05). CONCLUSIONS NBP can improve the expressions of VEGF and bFGF in serum of ACI patients, and its effect is superior to that of conventional drugs.

Abstract
PURPOSE 'Affective prosody' defines the supra-segmental features of speech that, when manipulated, can change the type and intensity of emotion conveyed by the speaker. Although the right hemisphere is predominantly linked to the processing of affective prosodic cues, existing literature also suggests that damage to the left hemisphere can result in similar deficits. This study aims to demonstrate, and add to the evidence, that patients with left-hemisphere injury experience difficulties with affective prosodic perception and production, measured via a new combination of assessments and analyses. It is also hypothesised that aphasia severity will be correlated with impaired processing of affective prosody. RESULTS Stroke and control participants differed significantly on prosody perception tests of matching auditory affective cues to visual images. Prosodic production was measured by participants vocalising different affective expressions of words and monosyllables - from which significant differences were found in perceptual judgements of emotion accuracy and intensity, and acoustic analyses of pitch range and variance. There were significant correlations between participants' Western Aphasia Battery (WAB) scores, quality of life, and prosody production. CONCLUSION Individuals with left-hemisphere damage after stroke have impaired affective prosodic perception and production that may be associated with reduced quality of life.

Abstract
OBJECTIVE The objective of this study was to evaluate the efficacy and safety of intravenous vinpocetine administration as part of a comprehensive treatment for acute cerebral infarction in a Chinese population. METHODS 610 acute cerebral infarction patients were randomized into two groups: the vinpocetine group (469 patients) received cytidine disphosphate choline 0.4-0.5 g in combination with aspirin 75-100 mg or clopidogrel 75 mg once daily, plus vinpocetine 30 mg intravenously once daily for 7 days, while the control group (141 patients) received cytidine disphosphate choline 0.4-0.5 g in combination with aspirin 75-100 mg or clopidogrel 75 mg once daily for 7 days. Additionally, patients received medications for symptoms such as hypertension, hyperglycemia, hyperlipidemia, and intracranial hypertension when necessary. Mini-Mental State Examination (MMSE), National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale, and Barthel Index (BI) scores and transcranial doppler (TCD) were assessed at baseline, 7, 14, and 90 days after treatment. Adverse events (AEs) and abnormalities in blood, urine, liver, and kidney function were monitored. RESULTS MMSE, NIHSS, and BI scores were significantly higher in the vinpocetine group than in the control group 90 days after treatment, indicating significantly improved cognitive skill, neurological function, and quality of life (QOL) in the vinpocetine group versus the control group. Importantly, such effects of vinpocetine were maintained over time. In addition, TCD monitoring showed significantly increased cerebral blood flow associated with vinpocetine versus control. No significant difference in safety was noted between the two groups. CONCLUSIONS When used as part of treatment for acute cerebral infarction, vinpocetine improves patients' cerebral blood flow, cognitive quality, neurological functions, and QOL. Vinpocetine could be an effective and safe component of treatment regimen for acute cerebral infarction.

Abstract
PURPOSE OF RESEARCH Since, transient focal cerebral ischaemia exhibits detrimental effect not only during the course of ischaemia but also after the onset of reperfusion, the current study is focussed on identifying the appropriate therapeutic time point at which NG-nitro-l-arginine methyl ester (l-NAME) exerts better neuroprotection. PRINCIPAL RESULTS Pre-ischaemic administration of l-NAME ameliorated neurological deficits much better than the during ischaemic and post-ischaemic groups. Pre-ischaemic l-NAME has also mitigated glutamate excitotoxicity, increased glutamine synthetase activity, ATP and NAD levels, decreased nitrate/nitrite content, down regulated TNF-α and upregulated IL-10 expressions and reduced the cerebral infarction significantly than the during ischaemic and post-ischaemic groups. MAJOR CONCLUSION Current study revealed that l-NAME improved neurological deficit at the pre-ischaemic state in transient focal cerebral ischaemia and has also significantly ameliorated glutamate excitotoxicity. Though l-NAME showed neuroprotective effects when administered at during and post-ischaemia (during reperfusion), it exerts considerable neuroprotection when administered pre-ischaemically.

Abstract
Aim The aim of this study was to investigate the association of infarct location with post-stroke executive dysfunction. Methods One hundred seventy-seven patients hospitalized with acute infarction were enrolled. General information and NIHSS score at admission were recorded. The infarct site was recorded from magnetic resonance T2-W1 and FLAIR images, and the extent of white matter disease was assessed using the Fazekas score. Seven days after symptoms, executive function was assessed using the validated Chinese version of Mattis Dementia Rating Scale (MDRS) Initiation/Perseveration (I/P) [MDRS I/P]. Results The average MDRS I/P score of the 177 infarction patients was 24.16±5.21, considerably lower than the average score (32.7±3.1) of a control group of normal individuals. Patients with infarcts in the corona radiata or basal ganglia had significantly lower MDRS I/P scores that those without infarcts at these locations. The number of infarcts in the basal ganglia was also significantly associated with low MDRS I/P scores. Male gender and low NIHSS score were significantly associated with low MDRS I/P score, and high-density lipoprotein cholesterol was significantly associated with high MDRS I/P score. The number of infarcts in areas other than the basal ganglia as well as corona radiata and the extent of white matter disease had no influence on this score. Conclusions The number of infarcts in the basal ganglia corona radiata, low NIHSS score, and male gender are significantly and independently related to poor executive function (that is, low MDRS I/P score) after acute infarct.

Abstract
PURPOSE The purpose of this article was to illustrate the importance of the implementation of cognitive-communication screenings in acute stroke and to discuss the need for further research on whether and how these screenings are implemented. Cognitive-communication screenings after stroke are the subject of existing practice guidelines and are supported by accumulated evidence. METHOD The author uses an autoethnographic narrative--a tool founded in phenomenology--to provide an in-depth description of the experiences of a family in which one member experienced right-hemispheric stroke. She uses systematic introspection to produce a narrative using literary techniques. RESULTS The narrative illustrates the experiences of one family when one of their members has a right-hemisphere stroke, and cognitive-communication impairments are never formally identified by professionals involved in the patient's care. CONCLUSIONS The narrative is linked to the published literature and the importance of identifying and managing cognitive-communication impairments after stroke. A model of implementation science is presented as one way to consider the challenges clinicians face when attempting to implement evidence-based practices. The model and examples from other fields show avenues for further research.

Abstract
We provide rigorous psychometric evidence for distinct patterns of cognitive impairment for Alzheimer's disease (AD) and cerebral infarctions using 440 participants from the Religious Order Study. Latent variable models were used to decompose the effects of AD pathology and cerebral infarctions assessed at autopsy on overall cognition and specific neuropsychological tests at one and five years prior to death. Results support clinical and univariate psychometric analyses that memory impairment is more pronounced in AD, and executive impairment is more pronounced in the presence of cerebral infarctions. These specific effects are subtle relative to the stronger associations of both AD neuropathology and cerebral infarctions with overall levels of cognitive impairment.

Abstract
The latest studies have adopted software technology to turn the battery-free wireless mouse into a high performance object location detector using a newly developed object location detection program (OLDP). This study extended OLDP functionality to assess whether two patients recovering from cerebral vascular accidents would be able to actively perform occupational activities by controlling their favorite environmental stimulation using battery-free wireless mice and OLDP software. Using an ABAB design we found substantial increases in both participants' target responses (i.e. the performance of occupational activities) to activate the control system to produce environmental stimulation during intervention phrases. The practical and developmental implications of the findings are discussed.

Abstract
BACKGROUND Our aim was to investigate the effect of health-related quality of life (HRQOL) on subsequent mortality in young ischemic stroke patients in a population-based study. METHODS Young ischemic stroke patients were invited to a follow-up on average 6 years after their index stroke. HRQOL was measured by Short-Form 36 (SF-36) and the Nottingham Health Profile (NPH). Data on socioeconomic and functional states were obtained. Subsequent survival was obtained by examining the official population registry. Multivariate analyses were performed. RESULTS One hundred eighty-eight patients were included. The mean age on follow-up was 48 years, and the subsequent follow-up period was 12 years. Cox regression analysis revealed that mortality was associated with NHP sum score (P < .001) after adjusting for age (P = .09), sex (P = .11), and alcoholism (P = .04). Cox regression analyses, including subscores of SF-36 or NHP separately, revealed that mortality was associated with pain (P = .05), sleep disturbances (P = .02), and physical function (P = .02) after adjusting for confounders. CONCLUSIONS Poor HRQOL is associated with subsequent long-term mortality in young adults with ischemic stroke and this may pertain particularly to pain, sleep disturbances and low physical fitness.
