Abstract
OBJECTIVES To investigate the prevalence of coincident anticoagulation in patients with cognitive disorders and possible or probable cerebral amyloid angiopathy (CAA) as well as the relationship between the presence of oral anticoagulation and CAA-specific lesion load. MATERIALS AND METHODS Patients with subjective cognitive decline (SCD), amnestic and non-amnestic mild cognitive impairment (aMCI/naMCI), Alzheimer's disease (AD), mixed dementia (MD) and vascular dementia (VD) who presented to our outpatient dementia clinic between February 2016 and October 2020 were included in this retrospective analysis. Patients underwent cranial magnetic resonance imaging (MRI). MRI data sets were analyzed regarding the presence of CAA-related MRI biomarkers to determine CAA prevalence. Presence of anticoagulant therapy was determined by chart review. RESULTS Within the study period, 458 patients (209 male, 249 female, mean age 73.2 ± 9.9 years) with SCD (n = 44), naMCI (n = 40), aMCI (n = 182), AD (n = 120), MD (n = 68) and VD (n = 4) were analyzed. A total of 109 patients (23.8%) were diagnosed with possible or probable CAA. CAA prevalence was highest in aMCI (39.4%) and MD (28.4%). Of patients with possible or probable CAA, 30.3% were under platelet aggregation inhibition, 12.8% were treated with novel oral anticoagulants and 3.7% received phenprocoumon treatment. Regarding the whole study cohort, patients under oral anticoagulation showed more cerebral microbleeds (p = 0.047). There was no relationship between oral anticoagulation therapy and the frequency of cortical superficial siderosis (p = 0.634). CONCLUSION CAA is a frequent phenomenon in older patients with cognitive disorders. Almost half of CAA patients receive anticoagulant therapy. Oral anticoagulation is associated with a higher number of cortical and subcortical microbleeds.

Abstract
The peripheral immune system response to Intracerebral Hemorrhage (ICH) may differ with ICH in different brain locations. Thus, we investigated peripheral blood mRNA expression of Deep ICH, Lobar ICH, and vascular risk factor-matched control subjects (n = 59). Deep ICH subjects usually had hypertension. Some Lobar ICH subjects had cerebral amyloid angiopathy (CAA). Genes and gene networks in Deep ICH and Lobar ICH were compared to controls. We found 774 differentially expressed genes (DEGs) and 2 co-expressed gene modules associated with Deep ICH, and 441 DEGs and 5 modules associated with Lobar ICH. Pathway enrichment showed some common immune/inflammatory responses between locations including Autophagy, T Cell Receptor, Inflammasome, and Neuroinflammation Signaling. Th2, Interferon, GP6, and BEX2 Signaling were unique to Deep ICH. Necroptosis Signaling, Protein Ubiquitination, Amyloid Processing, and various RNA Processing terms were unique to Lobar ICH. Finding amyloid processing pathways in blood of Lobar ICH patients suggests peripheral immune cells may participate in processes leading to perivascular/vascular amyloid in CAA vessels and/or are involved in its removal. This study identifies distinct peripheral blood transcriptome architectures in Deep and Lobar ICH, emphasizes the need for considering location in ICH studies/clinical trials, and presents potential location-specific treatment targets.

Abstract
Die Durchführung einer oralen Antikoagulation ist bei Patienten mit einer zerebralen Amyloidangiopathie eine therapeutische Herausforderung. Die Assoziation der zerebralen Amyloidangiopathie mit Lobärblutungen, eine hohe Mortalität intrazerebraler Blutungen insbesondere unter oraler Antikoagulation sowie das hohe Rezidivrisiko solcher Blutungen erfordern eine strenge und interdisziplinäre Risiko-Nutzen-Abwägung. Vitamin-K-Antagonisten erhöhen das Risiko für die mit intrazerebralen Blutungen vergesellschaftete Mortalität um 60 % und sollten daher möglichst vermieden bzw. speziellen klinischen Situationen (z. B. mechanischer Aortenklappenersatz) vorbehalten sein. Auch der Einsatz von neuen oralen Antikoagulanzien und Thrombozytenaggregationshemmern bedarf einer strengen Risiko-Nutzen-Abwägung, da auch diese Substanzen das zerebrale Blutungsrisiko erhöhen. Insbesondere bei Patienten mit einer absoluten Arrhyhtmie bei Vorhofflimmern ist der interventionelle Vorhofohrverschluss eine therapeutische Alternative. Darüber hinaus sind weitere klinische Implikationen bei Patienten mit zerebraler Amyloidangiopathie Gegenstand dieser Literaturübersicht, beispielsweise Besonderheiten nach akutem ischämischem Schlaganfall und erforderlicher Sekundärprophylaxe, bei vorherigen intrazerebralen Blutungen und bei Patienten mit kognitiven Defiziten.

Abstract
The authors sought to explore whether hypertension classification was risk factor for lobar and non‐lobar hypertensive intracerebral hemorrhage (HICH) and the prognosis in patients with hematoma. This retrospective cohort study was conducted on HICH patients admitted at the First Affiliated Hospital of Soochow University. Observations with first‐ever intracerebral hemorrhage (ICH) were recruited. The authors divided the brain image into three groups according to the location of ICH to predict whether there were significant differences between lobar and non‐lobar ICH. A Mann‐Whitney U test was used and this retrospective trial also compared the operation and mortality rates. Our cohort included 209 patients (73.7% male; median age:60.5±16.7). The overall incidence of lobar HICH was less than non‐lobar HICH (24.4% vs. 68.4%), 7.2% cases of mixed HICH was included in this analysis. In a Mann‐Whitney U test analyze, it indicated that there were significant differences in hypertension classification between lobar and non‐lobar HICH (Z = ‐3.3, p<.05). And the percentage of hematoma in lobar areas with relatively slightly high blood pressure (BP) (high normal and grade 1 hypertension) accounts for 52.9% versus 30.1% in non‐lobar areas. The increasing trends of the prevalent rate of lobar ICH with BP rising were not remarkable. The non‐lobar HICH showed a sharper increase in the condition of grade 3 hypertension compared with lobar HICH. During the period of research, the fatality of lobar hemorrhage was 2.9% versus 7.7% (non‐lobar). Besides, the fatality incidence of HICH with relatively slightly high BP (high normal and grade 1 hypertension) was lower than poorly controlled hypertensive patients (grade 2 and grade 3 hypertension). (8.0% vs. 15.7%). The increase of hypertension classification will aggravate the occurrence of non‐lobar ICH and positively corrected with BP, but not in lobar areas. It is essential to understand the distinction influence of hypertension classification between lobar and non‐lobar ICH.

Abstract
BACKGROUND AND OBJECTIVE Functional outcome after spontaneous intracerebral hemorrhage (ICH) may vary depending on hematoma volume and location. We assessed the interaction between hematoma volume and location, and modified the original ICH score to include such an interaction. METHODS Consecutive ICH patients were enrolled in the Intracerebral Hemorrhage Outcomes Project from 2009 to 2017. Inclusion criteria were age≥18 years, baseline modified Rankin Scale (mRS) score 0-2, neuroimaging, and follow-up. Functional dependence and mortality were defined as 90-day mRS>2 and death, respectively. A location ICH score was developed using multivariable regression and area under the receiver operator characteristic curve (AUROC) analyses. RESULTS The study cohort comprised 311 patients, and the derivation and validation cohorts comprised 209 and 102 patients, respectively. Interactions between hematoma volume and location predicted functional dependence (p = 0.008) and mortality (p = 0.025). The location ICH score comprised age≥80 years (1 point), Glasgow Coma Scale score (3-9 = 2 points; 10-13 = 1 point), volume-location (lobar:≥24 mL=2 points, 21-24 mL=1 point; deep:≥8 mL=2 points, 7-8 mL=1 point; brainstem:≥6 mL=2 points, 3-6 mL=1 point; cerebellum:≥24 mL=2 points, 12-24 mL=1 point), and intraventricular hemorrhage (1 point). AUROC of the location ICH score was higher in functional dependence (0.883 vs. 0.770, p = 0.002) but not mortality (0.838 vs. 0.841, p = 0.918) discrimination compared to the original ICH score. CONCLUSIONS The interaction between hematoma volume and location exerted an independent effect on outcomes. Excellent discrimination of functional dependence and mortality was observed with incorporation of location-specific volume thresholds into a prediction model. Therefore, the volume-location relationship plays an important role in ICH outcome prediction.

Abstract
OBJECTIVE To investigate the prognostic relevance of cortical superficial siderosis (cSS) in patients with cerebral amyloid angiopathy (CAA). METHODS A total of 302 patients fulfilling clinical and imaging criteria for probable or possible CAA were enrolled into a prospective, multicenter cohort study and followed for 12 months. cSS was assessed on T2*/susceptibility-weighted imaging MRI. The predefined primary composite endpoint was incident stroke or death in patients with cSS compared to those without. Secondary analyses included cerebrovascular events and functional outcome measured by the modified Rankin Scale (mRS). Multiple regression analysis was performed to adjust for possible confounders. RESULTS cSS prevalence was 40%. The primary endpoint occurred more frequently in patients with cSS (22%, 27/121) compared to those without (8%, 15/181, p = 0.001). Rates of CAA-related incident intracranial hemorrhage were 17% (cSS) and 4% (no cSS, p = 0.0003). The proportion of patients being functionally independent (mRS 0-2) 12 months from baseline were 59% (cSS) and 82% (no cSS, p = 0.00002). Presence of cSS was associated with the primary endpoint (adjusted odds ratio [OR] 1.2, 95% confidence interval [CI] 1.1-1.3, p = 0.0005), incident intracranial hemorrhage (adjusted OR 1.2, 95% CI 1.1-1.3, p = 0.0003), and less favorable outcome as assessed by the mRS (common OR 1.9, 95% CI 1.2-3.1, p = 0.009). Similar results were obtained in analyses restricted to patients with probable CAA and to patients with disseminated cSS (all p < 0.005). CONCLUSIONS Patients with cSS and suspected CAA are at high risk for CAA-related incident intracranial hemorrhage and poor functional outcome. Both the presence and extent of cSS have prognostic relevance and may influence clinical decision-making.

Abstract
Objective Rehemorrhage is the most severe complication of postoperative patients with spontaneous intracerebral hemorrhage. The aim of the present study was to assess independent predictors of rehemorrhage and find the possibility of preventing rehemorrhage in postoperative patients with spontaneous intracerebral hemorrhage (sICH). Methods Medical records of 263 postoperative patients with sICH from our Hospital were reviewed. The relationships between rehemorrhage and parameters were examined by univariate and multivariate analyses. The parameters include time from onset to surgery, hematologic paremeters, neuroimaging characteristics, level and variability of systolic blood pressure, medical histories, operation duration, and blood loss. In addition, relationship between rehemorrhage and clinical outcome were analyzed by using multivariate analyses. Results Thirty-five (13.31%) patients experienced rehemorrhage after operation. Multivariate analyses indicated that the following factors were independently associated with rehemorrhage : history of diabetes mellitus (odds ratio [OR], 2.717; 95% confidence interval [CI], 1.005–7.346; p=0.049), and midline shift (for every 1 mm increase, OR, 1.117; 95% CI, 1.029–1.214; p=0.009). Rehemorrhage was an independent risk factor of poor functional outcome (OR, 3.334; 95% CI, 1.094–10.155; p=0.034). Conclusion Our finding revealed that history of diabetes mellitus and admission midline shift were possibly associated with rehemorrhage in postoperative patients with sICH.

Influence of Prior Nicotine and Alcohol Use on Functional Outcome in Patients after Intracerebral Hemorrhage. J Stroke Cerebrovasc Dis 2017; 27:892-899. [PMID: 29191740 DOI: 10.1016/j.jstrokecerebrovasdis.2017.10.029] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2017] [Revised: 10/19/2017] [Accepted: 10/23/2017] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND The influence of prior nicotine or alcohol use (legal drug use [LDU]) on outcome measures after intracerebral hemorrhage (ICH) is insufficiently established. We investigated drug-specific associations with (1) neuroradiologic and clinical parameters and (2) functional long-term outcome after ICH. METHODS This observational cohort study analyzed consecutive spontaneous patients with ICH (n = 554) from our prospective institutional registry over a 5-year study period (January 2010 to December 2014). We compared no-LDU patients with LDU patients, and patients using only nicotine, only alcohol, or both. To account for baseline imbalances, we reanalyzed cohorts after propensity score matching. RESULTS Prevalence of prior LDU was 197 of 554 (35.6%), comprising 94 of 554 (17.0%) with only nicotine use, 33 of 554 (6.0%) with only alcohol use, and 70 of 554 (12.6%) with alcohol and nicotine use. LDU patients were younger (65 [56-73] versus 75 [67-82], P <.01), less often female (n = 61 of 197 [31.0%] versus n = 188 of 357 [52.7%], P <.01), had more often prior myocardial infarction (n = 29 of 197 [14.7%] versus n = 24 of 357 [6.7%], P <.01), and in-hospital complications (sepsis or systemic inflammatory response syndrome: n = 95 of 197 [48.2%] versus n = 98 of 357 [27.5%], P <.01; pneumonia: n = 89 of 197 [45.2%] versus n = 110 of 357 [30.8%], P <.01). Except for an increased risk of pneumonia (odds ratio 2.22, confidence interval [1.04-4.75], P = .04) in patients using both nicotine and alcohol, we detected no significant differences upon reanalysis after propensity score matching of neuroradiologic or clinical parameters, complications, or long-term outcome between patients with and without LDU (mortality: n = 48 of 150 [32.0%] versus n = 45 of 150 [30.0%], P = .71; favorable outcome [modified Rankin Scale 0-3]: n = 56 of 150 [37.3%] versus n = 53 of 150 [35.3%], P = .72). CONCLUSIONS Prior nicotine use, alcohol use, and their combination were associated with significant differences in baseline characteristics. However, adjusting for unevenly balanced baseline parameters revealed no differences in functional long-term outcome after ICH.

Abstract
BACKGROUND AND PURPOSE The characteristics of intracerebral hemorrhage (ICH) may vary by ICH location because of differences in the distribution of underlying cerebral small vessel diseases. Therefore, we investigated the incidence, characteristics, and outcome of lobar and nonlobar ICH. METHODS In a population-based, prospective inception cohort study of ICH, we used multiple overlapping sources of case ascertainment and follow-up to identify and validate ICH diagnoses in 2010 to 2011 in an adult population of 695 335. RESULTS There were 128 participants with first-ever primary ICH. The overall incidence of lobar ICH was similar to nonlobar ICH (9.8 [95% confidence interval, 7.7-12.4] versus 8.6 [95% confidence interval, 6.7-11.1] per 100 000 adults/y). At baseline, adults with lobar ICH were more likely to have preceding dementia (21% versus 5%; P=0.01), lower Glasgow Coma Scale scores (median, 13 versus 14; P=0.03), larger ICHs (median, 38 versus 11 mL; P<0.001), subarachnoid extension (57% versus 5%; P<0.001), and subdural extension (15% versus 3%; P=0.02) than those with nonlobar ICH. One-year case fatality was lower after lobar ICH than after nonlobar ICH (adjusted odds ratio for death at 1 year: lobar versus nonlobar ICH 0.21; 95% confidence interval, 0.07-0.63; P=0.006, after adjustment for known predictors of outcome). There were 4 recurrent ICHs, which occurred exclusively in survivors of lobar ICH (annual risk of recurrent ICH after lobar ICH, 11.8%; 95% confidence interval, 4.6%-28.5% versus 0% after nonlobar ICH; log-rank P=0.04). CONCLUSIONS The baseline characteristics and outcome of lobar ICH differ from other locations.

Abstract
Intracerebral hemorrhage (ICH, or macrobleeds) and cerebral microbleeds-smaller foci of hemosiderin deposits commonly detected by magnetic resonance imaging of older adults with or without ICH-are both associated with an increased risk of future ICH. These hemorrhagic pathologies also share risk factors with ischemic thromboembolic conditions that may require antithrombotic therapy, requiring specialists in cardiology, internal medicine, and neurology to weigh the benefits vs hemorrhagic risks of antithrombotics in individual patients. This paper will review recent advances in our understanding of hemorrhage prone cerebrovascular pathologies with a particular emphasis on use of these markers in decision making for antithrombotic use.

Abstract
Following quickly behind improvements in acute ischemic stroke care have been important advances in the understanding and management of intracerebral hemorrhage (ICH). Among these are accurate diagnosis of cerebral amyloid angiopathy (CAA) during life, recognition of the association between CAA and warfarin-related ICH, use of newer hemostatic treatments, and the combination of minimally invasive surgery with hematoma thrombolysis. Currently recommended management includes prompt evaluation of the patient at a facility with stroke and neurosurgical expertise, consideration of early surgery for patients with clinical deterioration or cerebellar hemorrhages larger than 3 cm, and early treatment of coagulopathies and other neurologic and medical complications. Over the past 2 years, two major randomized studies in ICH (comparing early surgery with best medical management and testing the utility of hemostatic treatment within 4 hours using recombinant factor VIIa) have yielded neutral results. This review focuses on comprehensive management of ICH in light of recent evidence.

Abstract
OBJECTIVE To evaluate the role of ACT gene polymorphism in primary spontaneous intracerebral hemorrhage (PSICH) and ischemic stroke (IS). METHODS 193 PSICH, 272 IS and 188 controls were included from the same geographical area. The demographic and clinical stroke risk factors were noted. PSICH was confirmed by CT and IS by MRI. The location of stroke and size were noted. ACT gene polymorphism was analyzed by polymerase chain reaction. The ACT genotype and allele frequency in PSICH, IS and controls were compared. RESULTS The age of the PSICH was 56.9+/-13 years, IS 54+/-16.7 years and controls 54.8+/-10 years. 134 females were in study and 65 in control groups. In the controls the AA genotype was 30%, AT 51.1% and TT in 16% whereas these were 39.3%, 53% and 7.7% in PSICH and 34.6%, 53.3% and 12.1% in IS. The frequency of T allele in controls was 41.5%, PSICH 34.2% and IS 38.6%. There was no significant difference in genotype and allele frequency in PSICH, IS and controls as well as location and etiology of stroke. INTERPRETATION The ACT genotype and allele frequency are not different in Indian PSICH and IS compared to controls.

Abstract
BACKGROUND Among patients with intracerebral hemorrhage (ICH), warfarin use before onset leads to greater mortality. In a retrospective study, we sought to determine whether warfarin use is associated with larger initial hematoma volume, one determinant of mortality after ICH. METHODS We identified all patients hospitalized with ICH in the Greater Cincinnati region from January through December 2005. ICH volumes were measured on the first available brain scan by using the abc/2 method. Univariable analyses and a multivariable generalized linear model were used to determine whether international normalized ratio (INR) influenced initial ICH volume after adjusting for other factors, including age, race, sex, antiplatelet use, hemorrhage location, and time from stroke onset to scan. RESULTS There were 258 patients with ICH, including 51 patients taking warfarin. In univariable comparison, when INR was stratified, there was a trend toward a difference in hematoma volume by INR category (INR <1.2, 13.4 mL; INR 1.2-2.0, 9.3 mL; INR 2.1-3.0, 14.0 mL; INR >3.0, 33.2 mL; p = 0.10). In the model, compared with patients with INR <1.2, there was no difference in hematoma size for patients with INR 1.2-2.0 (p = 0.25) or INR 2.1-3.0 (p = 0.36), but patients with INR >3.0 had greater hematoma volume (p = 0.02). Other predictors of larger hematoma size were ICH location (lobar compared with deep cerebral, p = 0.02) and shorter time from stroke onset to scan (p < 0.001). CONCLUSION Warfarin use was associated with larger initial intracerebral hemorrhage (ICH) volume, but this effect was only observed for INR values >3.0. Larger ICH volume among warfarin users likely accounts for part of the excess mortality in this group.

Abstract
BACKGROUND AND PURPOSE This study examines whether angiotensin-converting enzyme (ACE) gene polymorphisms are associated with the risk of spontaneous deep intracerebral hemorrhage (SDICH) in Taiwan using a case-control study. METHODS Totally, 217 SDICH patients and 283 controls were recruited. Associations of ACE A-240T and ACE I/D polymorphisms with SDICH were examined under the additive model and adjusted for gender, age, body mass index, total cholesterol level, smoking history, alcohol use, hypertension, and use of ACE inhibitors. RESULTS Hypertension, diabetes mellitus, family history of spontaneous intracerebral hemorrhage (SICH), and low cholesterol level increase risk of female SDICH, whereas hypertension, alcohol use, smoking history, family history of SICH, and low cholesterol level are an important risk factor for male SDICH. After adjusting for covariates, only haplotype ACE T-D (OR = 2.7, 95% CI, 1.1-6.5, P = 0.02) was associated with female SDICH. CONCLUSIONS This study demonstrates that environmental risk factors play a major role and ACE polymorphisms play a minor role in contributing risk of SDICH in Taiwan.

Abstract
The annual incidence rate of primary intracerebral hemorrhage (ICH) in Izumo City, Japan, appears to be the highest rate among those reported. Despite improvement of management and surgical therapy, the overall morbidity and mortality after ICH are still high. The author investigated the risk factors for ICH in patients in Izumo. A case-control study of 242 patients (137 men and 105 women with ages ranging from 34 to 97 years) with primary ICH was conducted in Izumo between 1991 and 1998. Hypertension, diabetes mellitus, heart disease, liver disease, alcohol consumption, cigarette smoking, and serum levels of total cholesterol, aspartate aminotransferase, and alanine aminotransferase were assessed as possible risk factors for ICH by using conditional logistic regression. The prevalence of hypertension among ICH patients was 77% and the odds ratio (OR) for hypertension was 17.07 (95% CI: 8.30-35.09), which are much higher than figures reported from Western countries. The OR for hypertension was higher in individuals < or = 69 years of age than in those > or = 70 years of age and lower for lobar hemorrhage than for hemorrhages at other sites. High serum total cholesterol (> or = 220 mg/dl) was the second most important risk factor for ICH (OR: 2.52; 95% CI: 1.23-5.14), and low total cholesterol (< 160 mg/dl) decreased the risk of ICH (OR: 0.47; 95% CI: 0.27-0.82). In contrast, heart disease decreased the risk of ICH, and there was no observed association between alcohol consumption, cigarette smoking, or diabetes mellitus and ICH. This study conducted in Izumo suggests that hypertension is the most important risk factor for ICH and contrary to most previous studies indicates that serum total cholesterol concentration is also positively associated with the risk of ICH. In contrast, heart disease may decrease the risk of ICH.

Abstract
OBJECTIVE To determine whether evidence from observational studies supports the widely held belief that hypertension is more commonly a risk factor for deep than for lobar supratentorial intracerebral haemorrhage. METHODS Studies comparing the frequency of hypertension as a risk factor for deep versus lobar supratentorial intracerebral haemorrhage, excluding haemorrhages with identified secondary causes, were identified and subjected to a meta-analysis. The effects of predefined methodological quality criteria on the results were assessed and other sources of bias were considered. RESULTS The pooled result from all 28 included studies (about 4000 patients) found hypertension to be about twice as common in patients with deep as in those with lobar haemorrhage (odds ratio (OR) 2.10, 95% confidence interval (95% CI) 1.82 to 2.42), but there was significant heterogeneity between studies. The pooled OR was less extreme for studies that used a pre-stroke definition of hypertension, were population based or included first-ever strokes only. In the three studies meeting all criteria (601 patients), deep haemorrhage was associated with a smaller, statistically significant excess of hypertension (OR 1.50, 95% CI 1.09 to 2.07). The OR for studies confined to younger patients seemed to be more extreme (12.32, 95% CI 6.13 to 24.77), but none of these studies fulfilled our methodological quality criteria. Additional, unquantified sources of bias included uncertainty about whether those doctors reporting brain scans were blind to hypertension status, uncertain reliability of the classification of haemorrhage location and variable rates of investigation for secondary causes. CONCLUSIONS An excess of hypertension was found in patients with deep versus lobar intracerebral haemorrhages without an identified secondary cause, but this may be due to residual, unquantified methodological biases.

Abstract
BACKGROUND AND PURPOSE The mechanisms responsible for headache in patients with intracerebral hemorrhage (ICH) are not completely understood. The present study was undertaken to analyze the headache-associated factors, the possible related biochemical mechanisms, and the headache potential predictors of outcome in spontaneous ICH. METHODS We prospectively studied 189 patients from a large cohort of 266 consecutive patients with supratentorial ICH admitted within the first 12 hours of symptoms onset. The presence of headache at stroke onset was evaluated in these patients. The volumes of the initial ICH, peripheral edema at 48 hours, and the residual cavity at 3 months were measured on CT scan. Glutamate, interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha levels were measured in blood samples obtained on admission. The Canadian Stroke Scale (CSS) and the modified Rankin Scale were used to evaluate stroke severity and neurological outcome, respectively. RESULTS Headache at onset of stroke was observed in 65 patients (34.4%). Patients who experienced headache had a significantly higher frequency of history of infection (P= .009) or inflammation (P= .045), as well as higher body temperature (P= .021), leukocyte count (P= .038), ESR (P= .011), and mass effect (P= .017) on admission. Plasma concentrations of IL-6 and TNF-alpha were significantly higher in patients with headache than in those without. Headache was an independent predictor of the residual cavity volume in patients with spontaneous ICH (odds ratio 6.49; 95% CI 2.51 to 16.78; P= .0001). CONCLUSIONS Headache at ICH onset is associated with clinical and biochemical markers of inflammation and is an independent predictor of higher residual cavity volume after spontaneous ICH.

Abstract
BACKGROUND Cerebral microbleeds, which result from microangiopathic changes following chronic hypertension, may reflect bleeding-prone microangiopathy. However, the distribution of these lesions has not been compared with that of lacunes, which represent occlusive type microangiopathy. OBJECTIVES To compare the cerebral distribution of microbleeds and lacunes and correlate their severity. METHODS The study population comprised 129 hypertensive patients who underwent brain magnetic resonance imaging (MRI), including gradient echo (GE) sequences. Cerebral microbleeds were counted using GE-MRI data, and lacunes were also counted by comparing T1 and T2 weighted MRI. To investigate the distributions, the number of patients with each type of lesion was compared, and the occurrence index (the total number of the specific lesions divided by the total number of patients) was examined statistically. Correlation analyses were done on the relations between the different grades of microbleeds, lacunes, and leukoaraiosis. RESULTS Cerebral microbleeds and lacunes were found at various foci in the brain, with a preference for the cortico-subcortical region and the deep grey matter. The occurrence index of microbleeds, but not of lacunes, was significantly higher in the cortico-subcortical region than in the deep grey matter. The severity of the microbleeds was positively correlated with the severity of lacunes, and both types of lesion were closely correlated with the degree of leukoaraiosis. CONCLUSIONS These data suggest that microbleeds and lacunes tend to occur to a similar extent in long standing hypertension, but not necessarily in the same locations.

Abstract
Cerebral amyloid angiopathy is a disorder in which deposition of amyloid within the arterial media and adventitia leads to intracerebral hemorrhage. Diagnosis during life has been hampered by the requirement for post-mortem examination for definitive diagnosis. The Boston Criteria for the diagnosis of cerebral amyloid angiopathy-related hemorrhage were developed in 1995 and 1996 in order to meet the need for a standardized set of diagnostic criteria that can be applied to living patients. Using a combination of clinical, radiologic, and pathologic data, these criteria reliably differentiate lobar intracerebral hemorrhage into categories of possible, probable, or definite based on the likelihood of underlying cerebral amyloid angiopathy. These criteria will be crucial for disease classification for future clinical studies.

Abstract
BACKGROUND AND PURPOSE Intracerebral hemorrhage (ICH) has a 30-day mortality rate of 40% to 50% and lacks a proven treatment. We report a preplanned, midpoint analysis of the first population-based, case-control study that examines both genetic and environmental risk factors of ICH. METHODS We prospectively identified cases of hemorrhagic stroke at all 16 hospitals in the Greater Cincinnati/Northern Kentucky region. All cases underwent medical record and neuroimaging review. Cases enrolled in the direct interview and genetic sampling arm of the study were matched to population-based control subjects by age, race, and sex. Multivariable logistic regression was performed to identify significant independent risk factors. RESULTS We enrolled 188 cases of ICH (67 lobar, 121 nonlobar) and 366 control subjects in the direct interview arm of the study. Significant independent risk factors for lobar ICH included the presence of an apolipoprotein E2 or E4 allele, frequent alcohol use, prior stroke, and first-degree relative with ICH. Significant independent risk factors for nonlobar ICH were hypertension, prior stroke, and first-degree relative with ICH. An increasing level of education was associated with a decreased risk of nonlobar ICH. The attributable risk of apolipoprotein E2 or E4 for lobar ICH was 29%, and the attributable risk of hypertension for nonlobar ICH was 54%. CONCLUSIONS There is significant epidemiological evidence that the pathophysiology of ICH varies by location. We estimate that a third of all cases of lobar ICH are attributable to possession of an apolipoprotein E4 or E2 allele and that half of all cases of nonlobar ICH are attributable to hypertension.

Abstract
The acute management of primary intracerebral or aneurysmal subarachnoid hemorrhage requires a comprehensive approach involving stabilization of the patient, surgical intervention, and continued intensive care treatment of medical and neurologic complications. The are several causes of intracerebral hemorrhage (ICH), including hypertension, cerebral amyloid angiopathy, sympathomimetic drugs, and coagulopathies. More recently, use of thrombolytic agents in the treatment of acute ischemic stroke has increased the risk of ICH. Treatment of intracerebral hemorrhage is based on blood pressure control, and, in selected cases, surgical evacuation of clot. Patients with aneurysmal subarachnoid hemorrhage may experience rebleeding, symptomatic vasospasm, or hydrocephalus. Medical management in the intensive care unit with careful attention to fluid and electrolyte balance, nutrition, cardiopulmonary monitoring, and close observation for changes in the neurologic exam is vital. This review examines the diagnosis and intensive care management of patients with intracerebral or subarachnoid hemorrhage, and reviews some of the newer therapies for treatment of these disorders.

Abstract
A high risk factor for spontaneous and often fatal lobar hemorrhage is cerebral amyloid angiopathy (CAA). We now report that CAA in an amyloid precursor protein transgenic mouse model (APP23 mice) leads to a loss of vascular smooth muscle cells, aneurysmal vasodilatation, and in rare cases, vessel obliteration and severe vasculitis. This weakening of the vessel wall is followed by rupture and bleedings that range from multiple, recurrent microhemorrhages to large hematomas. Our results demonstrate that, in APP transgenic mice, the extracellular deposition of neuron-derived beta-amyloid in the vessel wall is the cause of vessel wall disruption, which eventually leads to parenchymal hemorrhage. This first mouse model of CAA-associated hemorrhagic stroke will now allow development of diagnostic and therapeutic strategies.

Abstract
BACKGROUND Recurrent lobar intracerebral hemorrhage is the hallmark of cerebral amyloid angiopathy. The factors that predispose patients to early recurrence of lobar hemorrhage are unknown. One candidate is the apolipoprotein E gene, since both the epsilon2 and the epsilon4 alleles of apolipoprotein E appear to be associated with the severity of amyloid angiopathy. METHODS We performed a prospective, longitudinal study of consecutive elderly patients who survived a lobar intracerebral hemorrhage. The patients were followed for recurrent hemorrhagic stroke by interviews at six-month intervals and reviews of medical records and computed tomographic scans. RESULTS Nineteen of 71 enrolled patients had recurrent hemorrhages during a mean follow-up period of 23.9+/-14.8 months, yielding a 2-year cumulative rate of recurrence of 21 percent. The apolipoprotein E genotype was significantly associated with the risk of recurrence. Carriers of the epsilon2 or epsilon4 allele had a two-year rate of recurrence of 28 percent, as compared with only 10 percent for patients with the common apolipoprotein E epsilon3/epsilon3 genotype (risk ratio, 3.8; 95 percent confidence interval, 1.2 to 11.6; P=0.01). Early recurrence occurred in eight patients, four of whom had the uncommon epsilon2/epsilon4 genotype. Also at increased risk for recurrence were patients with a history of hemorrhagic stroke before entry into the study (two-year recurrence, 61 percent; risk ratio, 6.4; 95 percent confidence interval, 2.2 to 18.5; P<0.001). CONCLUSIONS The apolipoprotein E genotype can identify patients with lobar intracerebral hemorrhage who are at highest risk for early recurrence. This finding makes possible both the provision of prognostic information to patients with lobar hemorrhage and a method of targeting and assessing potential strategies for prevention.

Abstract
BACKGROUND AND PURPOSE Primary intracerebral hemorrhage (PICH) is a devastating illness with high early mortality. Hypertension is a major risk factor both for ischemic cerebrovascular disease and for intracranial hemorrhage. Survivors of PICH are at risk for both recurrent hemorrhage and ischemic cerebrovascular disease. We sought to determine the rate of recurrence of ICH or cerebral ischemia in a cohort of PICH patients at the Toronto Hospital, Toronto, Canada. METHODS A retrospective search of computerized hospital records from 1986 to 1996 for patients with a discharge diagnosis of intracerebral hemorrhage (International Classification of Diseases, Ninth Revision-Clinical Modification [ICD-9-CM] code 431) was conducted to identify the index cases. Charts were abstracted for demographic and clinical characteristics. CT scans, MR scans, or radiologist reports were reviewed. To determine recurrence, the database was linked to the Ontario Provincial Government Vital Statistics Registry and to the Canadian Institute for Health Information database of hospital discharge abstracts. Logistic regression analysis was used to identify predictive factors for mortality after PICH. A Cox proportional hazards model was fitted to identify predictive factors for recurrent ICH or stroke. RESULTS A total of 746 charts were identified by computer search. After abstraction, 423 index patients with PICH were identified. Of these, 27.4% died in the first 30 days of their admission. Predictors of death were age, intraventricular rupture of hemorrhage, and trilobar hemorrhage. The recurrence rate for PICH was 2.4% (95% CI 1.4% to 3. 9%) per year, whereas the recurrence rate for ischemic cerebrovascular disease was 3.0% (95% CI 1.8% to 4.7%) per year. The only significant predictor of readmission for ICH was lobar location of the index hemorrhage, with a hazard ratio of 3.8 (95% CI 1.2 to 12.0). CONCLUSIONS PICH has a high 30-day mortality rate. Survival from the initial insult portends a moderate risk of recurrence of 2. 4% per year for PICH and 3.0% per year for ischemic cerebrovascular disease. Patients with PICH are at risk for both ischemic stroke or TIA and recurrent hemorrhage; thus, PICH may be a marker for ischemic stroke. Patients with lobar hemorrhage have a 3.8-fold increased risk of recurrent ICH.

Abstract
AIMS To review the computed tomography (CT) features of intracerebral haemorrhage pathologically proven to be associated with cerebral amyloid angiopathy in order to facilitate recognition of the presence of cerebral amyloid angiopathy in life. METHODS We prospectively collected the clinical and brain imaging records of patients dying following an intracerebral haemorrhage who underwent a post-mortem examination and were found to have cerebral amyloid angiopathy. We reviewed the brain imaging to highlight features of the haemorrhage and of the rest of the brain common to these cases. RESULTS Seven patients aged 60-86 years were examined over a 30-month period. On CT, the notable features were that the haemorrhages appeared large, lobar, often extended through the cortex to the subarachnoid space or into the ventricles, and were multiple and recurrent in patients who survived the initial bleed. The high density (blood) within the haematoma tended to sediment posteriorly. CONCLUSIONS There are features on CT of cerebral amyloid angiopathy associated with spontaneous intracerebral haemorrhage which should raise the possibility of this underlying diagnosis. We suspect this condition is under-recognized in life, and should perhaps be considered more widely.

Abstract
Patients with intracerebral hemorrhage should be admitted to an intensive care unit for experienced neurologic nursing care and close attention to vital signs. We recommend gentle reduction in blood pressure in individuals who present with elevated readings and in whom hemorrhage is felt to be secondary to hypertension. For the vast majority of nontraumatic intracerebral hemorrhages, the indications for surgery and use of intracranial pressure monitoring devices remain unproven. Surgery is indicated for notable exceptions, such as for patients with cerebellar hematomas (3 mL or larger) and for patients with temporal lobe hematoma and impending brain stem compression. In general, intracranial pressure (ICP) monitoring is advised to help guide treatment with hyperosmolar agents and hyperventilation when increased ICP is suspected. For patients with smaller supratentorial hematomas who are alert or somnolent, conservative treatment is optimal. Similarly, we support conservative management in patients older than 70 years of age who present with a hemorrhage of more than 50 mL and a Glasgow Coma Scale (GCS) score of less than 8. Insufficient data exist from large randomized and controlled studies to recommend surgical intervention as definitive treatment for the group between these two extremes.

Abstract
BACKGROUND AND PURPOSE A prospective study was performed to evaluate neurological and functional outcome after spontaneous supratentorial bleeding. The aim of the study was to determine whether clinical or neuroradiological parameters could predict the outcome of these patients during the first hours of hospitalization. METHODS Two hundred seventy-nine patients--52 with thalamic, 87 with putaminal, and 140 with lobar hemorrhages--were followed prospectively and examined on admission and at 2 weeks, 3 months, and 6 months after onset. The patients underwent clinical (according to the Glasgow Coma Scale) and neuroradiological examinations on admission and were scored clinically and functionally (according to Stroke Severity score and Barthel Index) on the follow-up periods. Risk factors and the correlation between findings on admission and the latest clinical and functional results were calculated with the chi 2 test, Pearson correlation test, and Student's t test. Multivariate analysis was calculated with the stepwise regression test. RESULTS In all of the bleeding locations, lethal outcome was significantly correlated with size of the hematoma (P < .001) and Glasgow Coma Scale score on admission (P < .001). Intraventricular blood expansion was found to have a better prognosis in thalamic bleeding (P < .007) and a worse prognosis in lobar hemorrhage (P < .01). The functional outcome after 6 months was directly correlated with the size of the bleeding area in lobar and putaminal hemorrhages. No correlation was found in thalamic bleeding. A worse functional outcome was found in putaminocapsular bleeding (P = .004) and in patients with ischemic heart disease. A limited better recovery prognosis was found in patients with lobar hematoma in the temporal lobe (P = .052). CONCLUSIONS The probability of lethal outcome can be calculated on admission in all patients with supratentorial bleeding and in correlation with the location and size of the bleeding area and level of consciousness. Intraventricular expansion of blood is a better prognostic factor in thalamic bleeding and a worse one in lobar hematoma. Functional outcome is correlated with size of the bleeding area and level of consciousness on admission in putaminal and lobar hemorrhages but has no correlation to thalamic hemorrhage.

Abstract
BACKGROUND AND PURPOSE Focal neurological deficits (FNDs) in patients with arteriovenous malformations (AVMs) have been widely attributed to the phenomenon of "cerebral steal." The incidence of focal deficits was investigated in a large prospective sample. METHODS Using data from patient history and examination, CT or MRI, and transcranial Doppler sonography, we studied 152 consecutive, prospective AVM patients for evidence of FNDs unrelated to a hemorrhagic event. Feeding mean arterial pressure was measured during superselective angiography. RESULTS Two (1.3%) of 152 patients met the criteria for a progressive FND. Nonprogressive FNDs were seen in 11 (7.2%) patients (stable in 4.6%, reversible in 2.6%). The median observation time period was 17 months (range, 1 to 60 months). There were no differences in transcranial Doppler mean velocities in feeding arteries in FND versus non-FND groups (118 +/- 44 versus 112 +/- 37 cm/s, P > .05) or pulsatility indexes (0.53 +/- 0.20 versus 0.55 +/- 0.15, P > .05). Feeding artery pressure was similar in FND (n = 10) and non-FND (n = 96) groups (39 +/- 16 versus 39 +/- 16 mm Hg at a systemic pressure of 82 +/- 18 versus 75 +/- 14 mm Hg, NS). CONCLUSIONS Nonhemorrhagic focal neurological syndromes in AVM patients are infrequent. Progressive deficits are especially rare. There was no relation between feeding artery pressure or flow velocities and FND. There does not appear to be sufficient evidence to assign steal as an operative pathophysiological mechanism in the vast majority of AVM patients.

Abstract
BACKGROUND AND PURPOSE The aim of this study was to determine the 30-day mortality and morbidity of intracerebral hemorrhage in a large metropolitan population and to determine the most important predictors of 30-day outcome. METHODS We reviewed the medical records and computed tomographic films for all cases of spontaneous intracerebral hemorrhage in Greater Cincinnati during 1988. Independent predictors of 30-day mortality were determined using univariate and multivariate statistical analyses. RESULTS The 30-day mortality for the 188 cases of intracerebral hemorrhage was 44%, with half of deaths occurring within the first 2 days of onset. Volume of intracerebral hemorrhage was the strongest predictor of 30-day mortality for all locations of intracerebral hemorrhage. Using three categories of parenchymal hemorrhage volume (0 to 29 cm3, 30 to 60 cm3, and 61 cm3 or more), calculated by a quick and easy-to-use ellipsoid method, and two categories of the Glasgow Coma Scale (9 or more and 8 or less), 30-day mortality was predicted correctly with a sensitivity of 96% and a specificity of 98%. Patients with a parenchymal hemorrhage volume of 60 cm3 or more on their initial computed tomogram and a Glasgow Coma Scale score of 8 or less had a predicted 30-day mortality of 91%. Patients with a volume of less than 30 cm3 and a Glasgow Coma Scale score of 9 or more had a predicted 30-day mortality of 19%. Only one of the 71 patients with a volume of parenchymal hemorrhage of 30 cm3 or more could function independently at 30 days. CONCLUSIONS Volume of intracerebral hemorrhage, in combination with the initial Glasgow Coma Scale score, is a powerful and easy-to-use predictor of 30-day mortality and morbidity in patients with spontaneous intracerebral hemorrhage.

Abstract
BACKGROUND AND PURPOSE We sought to determine whether hypertension is less common in primary lobar hemorrhage than intracerebral hemorrhage in other locations and whether the frequency of hypertension in lobar hemorrhage diminishes with advancing age. METHODS We identified all cases of intracerebral hemorrhage in Greater Cincinnati during 1988 by review of hospital and autopsy records as well as computed tomographic and magnetic resonance scans. RESULTS During 1988, 66 primary lobar hemorrhages occurred, constituting 46% of all intracerebral hemorrhages in those under 75 years of age and 34% in those age 75 and older. A history of hypertension was present in 67% of patients with lobar, 73% of those with deep, 73% of those with cerebellar, and 78% of those with pontine hemorrhages. Left ventricular hypertrophy was present in 21% of patients with lobar, 27% of those with deep, and 47% of those with pontine/cerebellar hemorrhages. The frequency of hypertension in patients with lobar hemorrhage did not decrease with advancing age. CONCLUSIONS The proportion of all intracerebral hemorrhages that are lobar does not increase with advancing age. Hypertension is nearly as common in primary lobar hemorrhage as in deep, cerebellar, and pontine hemorrhages, and its importance as an associated condition for lobar hemorrhage does not diminish with advancing age.
