Meta-analysis and systematic review of the relationship between sex and the risk or incidence of poststroke aphasia and its types.

OBJECTIVE: To analyse and discuss the association of gender differences with the risk and incidence of poststroke aphasia (PSA) and its types, and to provide evidence-based guidance for the prevention and treatment of poststroke aphasia in clinical practice. DATA SOURCES: Embase, PubMed, Cochrane Library and Web of Science were searched from January 1, 2002, to December 1, 2023. STUDY SELECTION: Including the total number of strokes, aphasia, the number of different sexes or the number of PSA corresponding to different sex. DATA EXTRACTION: Studies with missing data, aphasia caused by nonstroke and noncompliance with the requirements of literature types were excluded. DATA SYNTHESIS: 36 papers were included, from 19 countries. The analysis of 168,259 patients with stroke and 31,058 patients with PSA showed that the risk of PSA was 1.23 times higher in female than in male (OR = 1.23, 95% CI = 1.19-1.29, P < 0.001), with a prevalence of PSA of 31% in men and 36% in women, and an overall prevalence of 34% (P < 0.001). Analysis of the risk of the different types of aphasia in 1,048 patients with PSA showed a high risk in females for global, broca and Wenicke aphasia, and a high risk in males for anomic, conductive and transcortical aphasia, which was not statistically significant by meta-analysis. The incidence of global aphasia (males vs. females, 29% vs. 32%) and broca aphasia (17% vs 19%) were higher in females, and anomic aphasia (19% vs 14%) was higher in males, which was statistically significant (P < 0.05). CONCLUSIONS: There are gender differences in the incidence and types of PSA. The risk of PSA in female is higher than that in male.

The diagnostic intersection of cognitive-communication disorders and aphasia secondary to TBI.

BACKGROUND & AIMS: The present retrospective study examines veterans and military personnel who have sustained a cognitive-communication deficit/disorder (CCD) and/or aphasia secondary to traumatic brain injury (TBI). The prevalence of each disorder secondary to TBI is identified and demographic factors are analysed to determine whether specific characteristics (age, gender, race and/or ethnicity) differentially influenced diagnosis (CCD or aphasia). METHODS & PROCEDURES: A retrospective analysis examining the prevalence of CCD and aphasia among US service personnel with a complicated mild-to-severe TBI treated over a 4-year period (1 January 2016-31 December 2019) was conducted. Medical diagnoses and demographic factors were obtained from administrative data repositories and a logistic regression was performed to identify the relationship between demographic factors and diagnoses. OUTCOMES & RESULTS: Analyses revealed that 8.8% of individuals studied had a secondary diagnosis of CCD (6.9%), aphasia (1.5%) or both (0.4%). This signifies 6863 cases of CCD, 1516 cases of aphasia and 396 cases of CCD and aphasia (dual diagnosis) per 100,000 individuals who have sustained a complicated mild-to-severe TBI. The proportion of cases observed with these diagnoses was consistent with the racial, gender and ethnic demographics of those diagnosed with TBI. Statistical modelling revealed that increased age is predictive of a diagnosis of aphasia relative to CCD. CONCLUSIONS & IMPLICATIONS: Service personnel sustaining TBIs are at increased risk of communication impairments with deficits observed across all gender, racial and ethnic demographics. CCD is more commonly observed than aphasia, though clinicians should be cognisant of both when performing assessments. Age is a factor that can influence diagnosis. WHAT THIS PAPER ADDS: What is already known on the subject Military personnel are at increased risk of communication disorders (CCDs) with TBI associated with multiple types of communication impairments including CCD, aphasia, dysarthria and apraxia of speech. What this paper adds to existing knowledge This paper examines CCD and aphasia occurring following TBI. The proportion of observed cases of CCD and aphasia secondary to TBI are calculated over a 4-year period and the prevalence of these disorders is provided. Additionally, statistical modelling is used to identify differences in the diagnosis of CCD relative to aphasia using the demographic factors of age, racial identity and ethnicity. What are the potential or actual clinical implications of this work? CCD is a frequently occurring issue following TBI, and the findings of this study demonstrate that it is a concern observed across gender, racial and ethnic lines. Advanced age is linked with the diagnosis of aphasia relative to CCD following TBI and should be a consideration during evaluation of patients who have sustained significant head trauma.

Incidence of Aphasia in Ischemic Stroke.

INTRODUCTION: A decrease in ischemic stroke (IS) incidence has been observed in high income countries during the last decades. Whether this has influenced the occurrence of aphasia in IS is uncertain. We therefore examined the incidence rate and potentially related determinants of aphasia in IS. METHODS: We prospectively examined consecutive patients admitted to hospital with first-ever acute IS between March 1, 2017, and February 28, 2018, as part of the Lund Stroke Register (LSR) Study, comprising patients from the uptake area of Skåne University Hospital, Lund, Sweden. Patients were assessed with National Institutes of Health Stroke Scale (NIHSS) at stroke onset. Presence of aphasia was evaluated with NIHSS item 9 (language). We registered IS subtypes and risk factors. To investigate possible temporal changes in aphasia incidence, we made comparisons with corresponding LSR data from 2005 to 2006. Incidence rates were calculated and adjusted to the European Standard Population (ESP) and to the Swedish population. RESULTS: Among 308 included IS patients, 30% presented with aphasia (n = 91; 95% CI: 25-35), a proportion of aphasia in IS that was similar to 2005-2006. The incidence rate of aphasia was 31 per 100,000 person-years adjusted to the ESP (95% CI: 25-38 per 100,000 person-years) corresponding to a significant decrease of 30% between 2005-2006 and 2017-2018. The decrease was significantly more pronounced in men. The initial severity of aphasia remained unchanged, with the majority of patients having severe to global aphasia. No significant differences between vascular stroke risk factors were noted among stroke patients with or without aphasia. CONCLUSION: Even though the overall IS incidence rate has decreased during the first decades of the 21st century, the proportion of IS patients with aphasia at stroke onset remains stable at 30%. Aphasia continues to be an important symptom that needs to be considered in stroke care and rehabilitation.

Association between aphasia and risk of dementia after stroke.

BACKGROUND AND PURPOSE: Although findings from published studies suggest post-stroke aphasia is associated with an increased risk of dementia, few studies have evaluated its association in a nationally representative cohort with long-term follow-up. No studies have reported data by type of stroke. Therefore, we examined the association between post-stroke aphasia and the risk of developing dementia. METHODS: Using claims data from Taiwan's universal health insurance program, a cohort of patients ≥18 years old with an initial hospitalization for stroke in 2002-2005 were identified and followed up until December 31, 2016. Patients with newly diagnosed aphasia during stroke hospitalization or within 6 months of discharge were defined as the aphasia group. Cox proportional hazards models were used to estimate hazard ratios (HRs) for developing overall, vascular, and non-vascular dementia in patients with and without post-stroke aphasia. RESULTS: During a median follow-up period of 7.9 and 8.6 years for the aphasia (n=17063) and non-aphasia groups (n=105940), respectively, overall dementia incidence was similar, whereas vascular dementia incidence was higher in the aphasia group (7.52 vs. 5.52 per 1000 person-years). The adjusted HRs (95% confidence intervals) were 1.11 (1.06-1.17), 1.42 (1.31-1.53), and 0.94 (0.88-1.01) for overall, vascular, and non-vascular dementia, respectively. The association between aphasia and the risk of vascular dementia did not differ by stroke type (P for interaction=0.43). The analysis of 16856 propensity score-matched pairs revealed similar results. CONCLUSION: Patients with post-stroke aphasia have an increased risk of developing vascular dementia irrespective of the type of stroke.

Swallowing, Oral Motor, Motor Speech, and Language Impairments Following Acute Pediatric Ischemic Stroke.

BACKGROUND AND PURPOSE: Following adult stroke, dysphagia, dysarthria, and aphasia are common sequelae. Little is known about these impairments in pediatric stroke. We assessed frequencies, co-occurrence and associations of dysphagia, oral motor, motor speech, language impairment, and caregiver burden in pediatric stroke. METHODS: Consecutive acute patients from term birth-18 years, hospitalized for arterial ischemic stroke (AIS), and cerebral sinovenous thrombosis, from January 2013 to November 2018 were included. Two raters reviewed patient charts to detect documentation of in-hospital dysphagia, oral motor dysfunction, motor speech and language impairment, and caregiver burden, using a priori operational definitions for notation and assessment findings. Other variables abstracted included demographics, preexisting conditions, stroke characteristics, and discharge disposition. Impairment frequencies were obtained by univariate and bivariate analysis and associations by simple logistic regression. RESULTS: A total of 173 patients were stratified into neonates (N=67, mean age 2.9 days, 54 AIS, 15 cerebral sinovenous thrombosis) and children (N=106, mean age 6.5 years, 73 AIS, 35 cerebral sinovenous thrombosis). Derived frequencies of impairments included dysphagia (39% neonates, 41% children); oral motor (6% neonates, 41% children); motor speech (37% children); and language (31% children). Common overlapping impairments included oral motor and motor speech (24%) and dysphagia and motor speech (23%) in children. Associations were found only in children between stroke type (AIS over cerebral sinovenous thrombosis) and AIS severity (more severe deficit at presentation) for all impairments except feeding impairment alone. Caregiver burden was present in 58% patients. CONCLUSIONS: For the first time, we systematically report the frequencies and associations of dysphagia, oral motor, motor speech, and language impairment during acute presentation of pediatric stroke, ranging from 30% to 40% for each impairment. Further research is needed to determine long-term effects of these impairments and to design standardized age-specific assessment protocols for early recognition following stroke.

Accuracy of NIH Stroke Scale for diagnosing aphasia.

OBJECTIVES: The National Institutes of Health Stroke Scale (NIHSS) has not been validated to diagnose aphasia in the stroke population. We therefore examined the diagnostic accuracy of NIHSS for detecting aphasia in acute ischemic stroke. METHODS: Consecutive patients with acute first-ever ischemic stroke were included prospectively in Lund Stroke Register Study at Skåne University Hospital, Sweden. Exclusion criteria were: (a) non-native Swedish; (b) obtundation (c) dementia or psychiatric diagnosis. Patients were assessed with NIHSS item 9 (range 0-3, where 1-3 indicate aphasia) by a NIHSS certified research nurse in the acute phase after stroke onset (median 3 days). Within 24 h after this assessment, a speech therapist evaluated the patients' language function with the comprehensive language screening test (LAST, range 0-15 where 0-14 indicates aphasia). Data were analyzed using LAST as 'reference standard'. RESULTS: We examined 221 patients. Among these, 23% (n = 50) had aphasia according to NIHSS (distribution of scores 0, 1, 2, 3 were n = 171, n = 29, n = 12, n = 9) compared to 26% (n = 58) with aphasia according to LAST (score ≤14; median = 11). Assuming LAST as reference standard, NIHSS gave 16 false negatives (NIHSS item 9 = 0) for aphasia (LAST scores range 8-14), and 8 false positives (NIHSS item 9 score = 1) for aphasia, yielding a sensitivity of 72% (0.59-0.83) and a specificity of 95% (0.91-0.98). CONCLUSIONS: When using NIHSS for screening and diagnosing aphasia in adults with acute ischemic stroke, patients with severe aphasia can be detected, however, some mild aphasias might be misclassified. Given the 72% sensitivity, absence of aphasia on the NIHSS should not be used to guide stroke treatment.

A Nationwide Multi-Center Questionnaire Survey on the Real-World State and Issues Regarding Post-Stroke Complications in Japan.

OBJECTIVES: Post-stroke complications affect stroke survivors across the world, although data on them are limited. We conducted a questionnaire survey to examine the real-world state and issues regarding post-stroke complications in Japan, which represents a super-aged society. MATERIALS AND METHODS: In 2018, a nationwide multi-center questionnaire survey was conducted in the top 500 Japanese hospitals regarding the number of stroke patients treated. Three questionnaires regarding post-stroke complications were mailed to the doctors responsible for stroke management. RESULTS: Responses were obtained from 251 hospitals (50.2%). The chief doctors responsible for stroke management answered the questionnaires. The number of stroke patients in the departments of neurology and neurosurgery was 338.3 ± 195.3 and 295.8 ± 121.8. Hospitals were classified using the categories secondary (n =142) and tertiary hospitals (n = 106); most hospitals were acute hospitals. Dementia was the most common complication (30.9%), followed by dysphagia (29.3%), and apathy (16.3%). Dementia was thought to be more common by neurologists than neurosurgeons, while apathy and bladder-rectal disorder were thought to be more common by neurosurgeons than neurologists (p = 0.001). The most difficult complication to treat was dysphagia (40.4%), followed by dementia (33.9%), epilepsy (4.1%), and fall (4.1%). Dementia was considered to lack clinical evidence regarding treatment (32.8%), followed by dysphagia (25.3%), and epilepsy (14.1%). Epilepsy was considered to lack clinical evidence among hospitals with a larger number of stroke cases (p = 0.044). CONCLUSION: This study revealed the current state and issues regarding post-stroke complications in Japan. Clinicians should be aware of the importance of post-stroke complications, although data on them remain unsatisfactory.

Value of Vascular and Non-Vascular Pattern on Computed Tomography Perfusion in Patients With Acute Isolated Aphasia.

BACKGROUND AND PURPOSE: Acute onset aphasia may be due to stroke but also to other causes, which are commonly referred to as stroke mimics. We hypothesized that, in patients with acute isolated aphasia, distinct brain perfusion patterns are related to the cause and the clinical outcome. Herein, we analyzed the prognostic yield and the diagnostic usefulness of computed tomography perfusion (CTP) in patients with acute isolated aphasia. METHODS: From a single-center registry, we selected a cohort of 154 patients presenting with acute isolated aphasia who had a whole-brain CTP study available. We collected the main clinical and radiological data. We categorized brain perfusion studies on CTP into vascular and nonvascular perfusion patterns and the cause of aphasia as ischemic stroke, transient ischemic attack, stroke mimic, and undetermined cause. The primary clinical outcome was the persistence of aphasia at discharge. We analyzed the sensitivity, specificity, positive and negative predictive values of perfusion patterns to predict complete clinical recovery and ischemic stroke on follow-up imaging. RESULTS: The cause of aphasia was an ischemic stroke in 58 patients (38%), transient ischemic attack in 3 (2%), stroke mimic in 68 (44%), and undetermined in 25 (16%). CTP showed vascular and nonvascular perfusion pattern in 62 (40%) and 92 (60%) patients, respectively. Overall, complete recovery occurred in 116 patients (75%). A nonvascular perfusion pattern predicted complete recovery (sensitivity 75.9%, specificity 89.5%, positive predictive value 95.7%, and negative predictive value 54.8%), and a vascular perfusion pattern was highly predictive of ischemic stroke (sensitivity 94.8%, specificity 92.7%, positive predictive value 88.7%, and negative predictive value 96.7%). The 3 patients with ischemic stroke without a vascular perfusion pattern fully recovered at discharge. CONCLUSIONS: CTP has prognostic value in the workup of patients with acute isolated aphasia. A nonvascular pattern is associated with higher odds of full recovery and may prompt the search for alternative causes of the symptoms.

Dysphagia, dysarthria and aphasia following a first acute ischaemic stroke: incidence and associated factors.

BACKGROUND AND PURPOSE: Dysphagia, dysarthria and aphasia are common symptoms following acute stroke; however, limited data are available from recent prospective clinical trials. The aim of this study was to determine the incidence and associated factors of dysphagia, dysarthria and aphasia following a first acute ischaemic stroke in patients admitted to a comprehensive stroke center. METHODS: All first ischaemic stroke patients admitted to the Stroke Unit of Ghent University Hospital within 48 h after symptom onset were enrolled in this prospective study between March 2018 and October 2019. Dysphagia and communication screenings were performed within 3 days after admission. When dysphagia, dysarthria and/or aphasia were assumed, standardized assessments were performed. Incidence rates were calculated as point estimates (%) with 95% confidence intervals (CI). Associated factors were calculated via multivariate binary logistic regression analyses. RESULTS: Dysphagia, dysarthria and aphasia were present in 23% (95% CI, 17-31), 44% (95% CI, 37-52) and 23% (95% CI, 17-30), respectively of 151 first ischaemic stroke patients [67 female, mean age 67 (SD 14) years]. Separate multivariate binary logistic regression analyses showed that dysphagia, dysarthria and aphasia were significantly associated with age-adjusted stroke severity at baseline [odds ratio (OR), 1.16; 95% CI, 1.09-1.23; OR, 1.13; 95% CI, 1.07-1.20 and OR, 1.11; 95% CI, 1.05-1.17 respectively]. Corrected for stroke severity, the risk for aphasia increased by 4% per year of age (OR, 1.04; 95% CI, 1.00-1.07). Adjusted for age and stroke severity, aphasia was significantly associated with large artery atherosclerosis as stroke etiology (OR, 3.91; 95% CI, 1.18-12.98). CONCLUSIONS: This trial showed a high incidence of dysphagia, dysarthria and aphasia following acute ischaemic stroke. Stroke severity was an associated factor for all three symptoms.

The assessment of severe lexical disorders in Italian individuals with aphasia.

Tests and batteries used in the evaluation of language impairments are overly complex and often ineffective (too difficult) in the assessment of post-stroke patients affected by severe aphasia (global aphasia). The present study reports details on the construction and standardization of a new Italian battery of tasks, specifically designed to assess severe lexical disorders in acquired aphasia (Battery for the Assessment of Severe Acquired Lexical Damage in Italian, BASALDI). The battery is composed of a common set of 64 stimuli (concrete nouns), belonging to both living and non-living categories, and consists of four lexical tasks assessing picture naming, repetition, reading aloud, and oral comprehension. The item selection was based on word frequency, word length, and phonological-articulatory complexity, namely the presence of continuant vs. plosive phones, a variable that may interact with word production in case of severe language damage. Standardization (naming agreement) of a new set of 64 colored images and normative data on Italian healthy subjects pooled across homogenous subgroups for age, gender, and education are reported. Finally, for the four tasks, percentile ranks and z-scores were calculated from a pool of 92 left brain-damaged patients affected by aphasia of different types and severity. The battery allows a fine investigation of lexical disorders, being suitable for diagnostic assessment of mild-to-moderate and severe aphasic lexical deficits, detection of changes over time, and possible dissociations between tasks.

Dysphagia and disability in minor strokes - An institutional study.

BACKGROUND: Minor strokes, defined as NIHSS ≤5 are considered non-disabling, associated with a favourable outcome. AIM: Our aim was to study prevalence and predictors of dysphagia in patients with minor stroke and its impact on functional outcome. METHODS: Single centre retrospective study of all minor strokes admitted to Comprehensive Stroke care centre with 1 year completed follow-up were recruited. Clinical and imaging details and follow-up data were extracted from medical records. RESULTS: We had 147 patients with minor stroke, 72.1% men with median age 61 years. 71% presented within 24 h of symptom onset. Most common etiology was lacunar .Median NIHSS at admission was 3(IQR 2). 85 patients had anterior circulation strokes and 34 had chronic infarcts in imaging.19 had significant dysphagia and 10 were discharged with nasogastric feeding tube. Admission NIHSS and white mater changes in imaging were predictive of post stroke dysphagia. Excellent recovery of dysphagia was found within 1 month post stroke in all, except one who required percutaneous gastrostomy. At 3 months 76% had excellent outcome. Presence of dysphagia and diabetes were found to be predictive of short term outcome, independent of admission stroke severity. At 12 months, post stroke dysphagia, female gender and white mater changes in imaging were predictive of unfavourable outcome. CONCLUSIONS: Minor strokes are disabling in a small fraction of patients. Over 10% of them can have significant post stroke dysphagia necessitating nasogastric feeding short term. This patient subgroup tend to have less favourable outcome on short and long term follow-up.

Prevalence and Impact of Aphasia among Patients Admitted with Acute Ischemic Stroke.

OBJECTIVE: Aphasia is one of the most severe symptoms in stroke patients, affecting one-third of acute stroke patients. We aimed to investigate the prevalence and outcomes of aphasia in patients with acute ischemic stroke (AIS). METHODS: We computed the weighted prevalence of aphasia in AIS patients using the 2003 to 2014 National Inpatient Sample databases. Crude regression model, multivariable regression model, and propensity score matching were used to evaluate the impact of aphasia on the clinical outcomes in AIS patients. We performed the Subpopulation Treatment Effect Pattern Plot (STEPP) analyses in propensity score matching cohort to visually display the effect of interaction between aphasia and age on the clinical outcomes. RESULTS: A total of 16.93% of 4,339,156 AIS patients identified were with aphasia. The proportion of patients with comorbid aphasia increased from 13.34% in 2003 to 21.94% in 2014 (P < .0001). The results of both multivariable regression model and propensity score matching analyses indicated aphasia in AIS as a risk factor for in-hospital deaths. Aphasia was linked to prolonged length of stay (0.66 day, P < .0001) and high hospitalization cost ($971.35, P < .0001). In the STEPP analyses, in-hospital mortality rate increased with age, and the rate was higher in patients with aphasia, but the ratios decreased with an increase in age. CONCLUSIONS: Prevalence of comorbid aphasia with AIS is increasing, and it has a significant impact on clinical outcomes. Additionally, aphasia shows a greater impact on survival and medical burden among young patients with AIS.

Incidence and Symptomatology of Vascular Crossed Aphasia in Bengali.

BACKGROUND: Crossed aphasia (CA) refers to aphasia following a right-hemispheric lesion in right-handed individuals. It has been suggested that the prevalence of CA differs with language, although its worldwide incidence, as reported by most studies, is less than 3%. OBJECTIVE: To find the incidence of CA in the Bengali language. METHODS: From 2016 to 2018, in a hospital located in a Bengali-speaking area of eastern India, 515 cases of first-ever stroke were documented, out of which 208 patients presented with aphasia (40.38%) according to their scores on the Bengali version of the Western Aphasia Battery. RESULTS: Among the patients with aphasia, 14 (6.73%; 8 men and 6 women) presented with CA. Of these, 10 were diagnosed with Broca aphasia and four with transcortical motor aphasia. No patient presented with Wernicke aphasia. CONCLUSIONS: The relatively high incidence of CA in our study suggests that bi-hemispheric language representation may be more prevalent in Bengali speakers than in speakers of other languages. The absence of crossed Wernicke aphasia in our study participants may represent a left-hemispheric advantage for receptive language abilities in Bengali speakers. Further studies are required to clarify whether idiosyncrasies in the Bengali language may be responsible for the differential brain representation of language seen in our study participants.

Pre-operative language ability in patients with presumed low-grade glioma.

In patients with low-grade glioma (LGG), language deficits are usually only found and investigated after surgery. Deficits may be present before surgery but to date, studies have yielded varying results regarding the extent of this problem and in what language domains deficits may occur. This study therefore aims to explore the language ability of patients who have recently received a presumptive diagnosis of low-grade glioma, and also to see whether they reported any changes in their language ability before receiving treatment. Twenty-three patients were tested using a comprehensive test battery that consisted of standard aphasia tests and tests of lexical retrieval and high-level language functions. The patients were also asked whether they had noticed any change in their use of language or ability to communicate. The test scores were compared to a matched reference group and to clinical norms. The presumed LGG group performed significantly worse than the reference group on two tests of lexical retrieval. Since five patients after surgery were discovered to have a high-grade glioma, a separate analysis excluding them were performed. These analyses revealed comparable results; however one test of word fluency was no longer significant. Individually, the majority exhibited normal or nearly normal language ability and only a few reported subjective changes in language or ability to communicate. This study shows that patients who have been diagnosed with LGG generally show mild or no language deficits on either objective or subjective assessment.

Blunted vocal affect and expression is not associated with schizophrenia: A computerized acoustic analysis of speech under ambiguous conditions.

INTRODUCTION: Patients with schizophrenia are consistently rated by clinicians as having high levels of blunted vocal affect and alogia. However, objective technologies have often failed to substantiate these abnormalities. It could be the case that negative symptoms are context-dependent. OBJECTIVES: The present study examined speech elicited under conditions demonstrated to exacerbate thought disorder. METHODS: The Rorschach Test was administered to 36 outpatients with schizophrenia and 25 nonpatient controls. Replies to separate "perceptual" and "memory" phases were analyzed using validated acoustic analytic methods. RESULTS: Compared to nonpatient controls, schizophrenia patients did not display abnormal speech expression on objective measure of blunted vocal affect or alogia. Moreover, clinical ratings of negative symptoms were not significantly correlated with objective measures. CONCLUSIONS: These findings suggest that in patients with schizophrenia, vocal affect/alogia is generally unremarkable under ambiguous conditions. Clarifying the nature of blunted vocal affect and alogia, and how objective measures correspond to what clinicians attend to when making clinical ratings are important directions for future research.

Aphasia Following Left Putaminal Hemorrhage at a Rehabilitation Hospital.

OBJECTIVE: We aimed to clarify the relationship between aphasia and hematoma type/volume in patients with left putaminal hemorrhage admitted to a rehabilitation facility. METHODS: We evaluated the relationship between the presence, type, and severity of aphasia and hematoma type/volume in 92 patients with putaminal hemorrhage aged 29-83 years. Hematoma type and volume were evaluated on the basis of CT images obtained at stroke onset. The Standard Language Test for Aphasia was conducted as part of the initial assessment. RESULTS: Aphasia was observed in 79 of 92 patients. A total of 31 patients had fluent aphasia, while 48 had non-fluent aphasia. Non-fluent aphasia often involved hematoma on the anterior limb of the internal capsule, while fluent aphasia often involved hematoma on the posterior limb of internal capsule. When the hematoma volume exceeded 20 mL, patients experienced difficulty in repeating spoken words. When hematoma volume exceeded 40 mL, non-fluent aphasia was observed in all patients. CONCLUSION: Our findings suggest that hematoma type and volume not only influence the development of aphasia following putaminal hemorrhage but also play a major role in determining the patient's fluency and repetition ability.

Post-Stroke Depression in Jordan: Prevalence Correlates and Predictors.

BACKGROUND: Post-stroke depression is among the most frequent neuropsychiatric complications of stroke, and it is associated with poor prognosis and outcomes. This study aimed to assess the prevalence of depression; its correlates, and predictors among patients with stroke in Jordan. METHODS: A cross-sectional, descriptive correlation design was used among 198 patients with stroke admitted to 9 hospitals all over Jordan. Depression was assessed using the validated hospital depression subscale (HDS) of the Hospital Anxiety and Depression scale. RESULTS: Study patients (mean age 56.62 years [SD = 14.2], 53% were males) experienced high prevalence of depression (76%); of these, 51.6% were categorized as higher depression category (a case of depression; HDS = 11-21). Factors that correspondingly predicted higher depression categories were low level of education (odds ratio [OR] = 3.347, 95% confidence interval [CI] = 2.920-23.949, P < .001), having a preparatory level of education (OR = 8.363, 95% CI = 1.24-9.034, P = .017), having comorbid chronic diseases (OR = .401, 95% CI = .190-.847), being a smoker (OR = 2.488, 95% CI = 1.105-5.604, P = .028), patients who reported inability to perform daily activities by themselves (OR = 3.688, 95% CI = 1.746-7.790, P = .001), and patients with comorbid dysphasia (OR = 12.884, 95% CI = 4.846-34.25, P < .001). CONCLUSIONS: Post-stroke depression is a significant health problem among Jordanian patients with stroke and warrants serious attention. Clinicians need to consider these important predictors when assessing and managing depression among patients at risk.

Comorbidities, Clinical Features, and Prognostic Implications of Cancer Patients with Cerebrovascular Disease.

PURPOSE: The objective of this study was to identify and describe the comorbidities, clinical features, and prognostic implications of cancer patients with cerebrovascular disease. MATERIALS AND METHODS: All patients with cerebrovascular disease (CVD) seen in the neuro-oncology unit at a cancer referral center from April 2010 to November 2016 were included; demographic, oncologic diagnosis, risk factors, and prognostic considerations were presented as well. RESULTS: We report on 256 patients with CVD and cancer, of whom 66% were women. The mean age at the time CVD occurred was 56 years. The most frequently associated malignancies were gynecologic (including breast cancer), hematologic, head and neck, and urologic. The men had more smoking and alcohol consumption history, hemorrhagic CVD, and urologic and hematologic malignancies. The women, besides gynecologic cancer, had more ischemic CVD. Thrombotic CVD, followed by embolic and hemorrhagic CVDs, was more frequent. A comorbid condition besides cancer was found in 71% of the patients. The most frequent clinical presentation was focal motor weakness, altered mental status, and aphasia. The 10-year mortality was 59%; higher rates were found in men, in those with hemorrhagic CVD, in tobacco users, and in those with altered mental status. CONCLUSIONS: Cancer is a well-known risk factor for stroke, which has been associated with a higher frequency in cancer. We found that ischemic stroke due to thrombosis and cardioembolism was more common, and gender, comorbidities, clinical presentation, and type of CVD, but not cancer type, were elements associated with prognosis.

[Incidence of aphasia in patients experiencing an ischemic stroke]. / Incidencia poblacional, características epidemiológicas y desenlace funcional de pacientes con ataque cerebrovascular isquémico y afasia.

BACKGROUND: Sequelae after a stroke are common and may lead to disability. Aphasia - defined as an acquired language disturbance - can cause important limitations in quality of life. AIM: To describe the epidemiological features of patients who had an aphasia after a first episode of ischemic stroke and their functional outcome at six months. MATERIAL AND METHODS: Review of a database of a population study on the incidence, 30-day case fatality rate, and prognosis of stroke performed in a northern Chilean city between 2000 and 2002. RESULTS: Aphasia was diagnosed in 28 of 142 patients in whom the disorder was sought (20%). The projected incidence rate in the city where the study was carried out is 7.06 per 100,000 inhabitants. The mean age of these 28 patients was 66 ± 20 years and 53% were women. The main risk factor for stroke was hypertension in 62%. The etiology of stroke was undetermined in 64% of these patients. Partial anterior circulation infarction was the most common stroke location in 61%. CONCLUSIONS: Twenty percent of patients with a first episode of ischemic stroke have aphasia.

Picturing the Size and Site of Stroke With an Expanded National Institutes of Health Stroke Scale.

BACKGROUND AND PURPOSE: The National Institutes of Health Stroke Scale (NIHSS) includes minimal assessment of cognitive function, particularly in right hemisphere (RH) stroke. Descriptions of the Cookie Theft picture from the NIHSS allow analyses that (1) correlate with aphasia severity and (2) identify communication deficits in RH stroke. We hypothesized that analysis of the picture description contributes valuable information about volume and location of acute stroke. METHODS: We evaluated 67 patients with acute ischemic stroke (34 left hemisphere [LH]; 33 RH) with the NIHSS, analysis of the Cookie Theft picture, and magnetic resonance imaging, compared with 35 sex- and age-matched controls. We evaluated descriptions for total content units (CU), syllables, ratio of left:right CU, CU/minute, and percent interpretive CU, based on previous studies. Lesion volume and percent damage to regions of interest were measured on diffusion-weighted imaging. Multivariable linear regression identified variables associated with infarct volume, independently of NIHSS score, age and sex. RESULTS: Patients with RH and LH stroke differed from controls, but not from each other, on CU, syllables/CU, and CU/minute. Left:right CU was lower in RH compared with LH stroke. CU, syllables/CU, and NIHSS each correlated with lesion volume in LH and RH stroke. Lesion volume was best accounted by a model that included CU, syllables/CU, NIHSS, left:right CU, percent interpretive CU, and age, in LH and RH stroke. Each discourse variable and NIHSS score were associated with percent damage to different regions of interest, independently of lesion volume and age. CONCLUSIONS: Brief picture description analysis complements NIHSS scores in predicting stroke volume and location.
