Improving detection of cerebral small vessel disease aetiology in patients with isolated lobar intracerebral haemorrhage. Stroke Vasc Neurol 2023; 8:26-33. [PMID: 35981809 PMCID: PMC9985798 DOI: 10.1136/svn-2022-001653] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 07/19/2022] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND AND PURPOSE We evaluate whether non-haemorrhagic imaging markers (NHIM) (white matter hyperintensity patterns, lacunes and enlarged perivascular spaces (EPVS)) can discriminate cerebral amyloid angiopathy (CAA) from hypertensive cerebral small vessel disease (HTN-cSVD) among patients with isolated lobar intracerebral haemorrhage (isolated-LICH). METHODS In patients with isolated-LICH, four cSVD aetiologic groups were created by incorporating the presence/distribution of NHIM: HTN-cSVD pattern, CAA pattern, mixed NHIM and no NHIM. CAA pattern consisted of patients with any combination of severe centrum semiovale EPVS, lobar lacunes or multiple subcortical spots pattern. HTN-cSVD pattern consisted of any HTN-cSVD markers: severe basal ganglia PVS, deep lacunes or peribasal ganglia white matter hyperintensity pattern. Mixed NHIM consisted of at least one imaging marker from either pattern. Our hypothesis was that patients with HTN-cSVD pattern/mixed NHIM would have a higher frequency of left ventricular hypertrophy (LVH), which is associated with HTN-cSVD. RESULTS In 261 patients with isolated-LICH, CAA pattern was diagnosed in 93 patients, HTN-cSVD pattern in 53 patients, mixed NHIM in 19 patients and no NHIM in 96 patients. The frequency of LVH was similar among those with HTN-cSVD pattern and mixed NHIM (50% vs 39%, p=0.418) but was more frequent in HTN-cSVD pattern compared with CAA pattern (50% vs 20%, p<0.001). In a regression model, HTN-cSVD pattern (OR: 7.38; 95% CI 2.84 to 19.20) and mixed NHIM (OR: 4.45; 95% CI 1.25 to 15.90) were found to be independently associated with LVH. CONCLUSION Among patients with isolated-LICH, NHIM may help differentiate HTN-cSVD from CAA, using LVH as a marker for HTN-cSVD.

Abstract
Objective To identify the predominant type of cerebral small vessel disease (SVD) and outcomes in patients with simultaneous multiple intracerebral hemorrhages (SMICH). Methods Consecutive patients with intracerebral hemorrhage (ICH) from a single-center prospective cohort were retrospectively reviewed. Presumed etiology was classified according to the SMASH-U criteria. Demographics, clinical and laboratory variables, and neuroimaging data were compared between patients with primary SMICH and those with single ICH. Functional outcomes were assessed using the modified Rankin scale 90 days after ICH. Results Of the 598 enrolled patients, 37 (6.2%) met the criteria for SMICH. Risk factors for SMICH included a high burden of deep cerebral microbleeds (CMBs) (odds ratio [OR] 1.06, 95% confidence interval [CI], 1.00–1.12; p = 0.040), white matter hyperintensity scores (OR 1.27, 95% CI 1.04–1.57; p = 0.021), history of ICH (OR 3.38, 95% CI 1.31–8.05; p = 0.008), and low serum magnesium levels (OR 0.01, 95% CI 0.00–0.25; p = 0.007). Based on the SMASH-U classification, 15(40.5%) SMICH were classified as hypertension, whereas 17 (45.9%) as undetermined-etiology. To further explore the potential microangiopathy underlying undetermined-SMICH, these patients with undetermined-etiology were compared to those with cerebral amyloid angiopathy-ICH, and were associated with a higher burden of deep CMBs but less severe centrum semiovale enlarged perivascular spaces. Likewise, compared with hypertension-ICH patients, those with undetermined SMICH were consistently associated with a higher deep CMB counts. Moreover, multivariate analysis revealed that SMICH was independently associated with poor outcomes (OR 2.23, 95%CI 1.03–4.76; p = 0.038). Conclusion Our results suggest that most patients with primary SMICH harbor hypertensive-SVD as principal angiopathy. Patients with SMICH are at a high risk of poor outcomes.

Deep versus Superficial Spontaneous Cerebellar Hemorrhages: Separated Vascular Etiologies with Different Clinical Consequences. World Neurosurg 2021; 150:e436-e444. [PMID: 33727202 DOI: 10.1016/j.wneu.2021.03.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 03/05/2021] [Accepted: 03/06/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Spontaneous cerebellar hemorrhage (CH) is a critical neurosurgical event. It is usually categorized as a homogenous group under the general term of deep/nonlobar intracerebral hemorrhage. However, increasing evidence suggests it is composed of 2 subgroups, separated from each other by their anatomic location (deep vs. superficial), as well as by their vascular etiology (small vessel disease vs. cerebral amyloid angiopathy). OBJECTIVE To identify any clinically significant differences between anatomically separated subgroups of CHs: deep versus superficial. METHODS This is a retrospective study on patients who were diagnosed with spontaneous CHs at a single tertiary center. On the basis of the radiologic location of the hematoma, patients were divided into 2 groups: deep (group 1) and superficial (group 2). Computerized medical records were extracted for multiple variables. RESULTS A total of 69 patients fulfilled the inclusion criteria. Fifty-three (77%) were in group 1, and 16 (23%) were in group 2. Having any vascular risk factor was associated with the highest odds ratio for having a deep CH. Morbid obesity (body mass index ≥30) and the use of antiplatelets were also associated with increased odds ratios. Group 1 is also associated with high prevalence of intraventricular hemorrhage, acute hydrocephalus, and less favorable outcome. CONCLUSIONS This study supports the notion that CH is most likely a heterogenous condition, composed of 2 subgroups, separated from each other in terms of anatomic location, vascular etiologies, and clinical consequences. Further studies on large cohort of patients are needed in order to accurately define the subgroups of this life-threatening event.

Abstract
OBJECTIVE To conduct a systematic review and meta-analysis of studies reporting on risk factors according to location of the intracerebral hemorrhage. METHODS We searched PubMed and Embase for cohort and case-control studies reporting ≥100 patients with spontaneous intracerebral hemorrhage that specified the location of the hematoma and reported associations with risk factors published until June 27, 2019. Two authors independently extracted data on risk factors. Estimates were pooled with the generic variance-based random-effects method. RESULTS After screening 10,013 articles, we included 42 studies totaling 26,174 patients with intracerebral hemorrhage (9,141 lobar and 17,033 nonlobar). Risk factors for nonlobar intracerebral hemorrhage were hypertension (risk ratio [RR] 4.25, 95% confidence interval [CI] 3.05-5.91, I 2 = 92%), diabetes mellitus (RR 1.35, 95% CI 1.11-1.64, I 2 = 37%), male sex (RR 1.63, 95% CI 1.25-2.14, I 2 = 61%), alcohol overuse (RR 1.48, 95% CI 1.21-1.81, I 2 = 19%), underweight (RR 2.12, 95% CI 1.12-4.01, I 2 = 31%), and being a Black (RR 2.83, 95% CI 1.02-7.84, I 2 = 96%) or Hispanic (RR 2.95, 95% CI 1.69-5.14, I 2 = 71%) participant compared with being a White participant. Hypertension, but not any of the other risk factors, was also a risk factor for lobar intracerebral hemorrhage (RR 1.83, 95% CI 1.39-2.42, I 2 = 76%). Smoking, hypercholesterolemia, and obesity were associated with neither nonlobar nor lobar intracerebral hemorrhage. CONCLUSIONS Hypertension is a risk factor for both nonlobar and lobar intracerebral hemorrhage, although with double the effect for nonlobar intracerebral hemorrhage. Diabetes mellitus, male sex, alcohol overuse, underweight, and being a Black or Hispanic person are risk factors for nonlobar intracerebral hemorrhage only. Hence, the term hypertensive intracerebral hemorrhage for nonlobar intracerebral hemorrhage is not appropriate.

Abstract
Disruption of the blood-brain barrier (BBB) might play a role in the pathophysiology of cerebral small vessel disease-related ICH. The aim of this study was to assess presence and extent of contrast agent leakage distant from the hematoma as a marker of BBB disruption in patients with spontaneous ICH. We prospectively performed 7 tesla MRI in adult patients with spontaneous ICH and assessed contrast leakage distant from the hematoma on 3D FLAIR images. Thirty-one patients were included (mean age 60 years, 29% women). Median time between ICH and MRI was 20 days (IQR 9-67 days). Seventeen patients (54%; seven lobar, nine deep, one infratentorial ICH) had contrast leakage, located cortical in 16 and cortical and deep in one patient. Patients with contrast leakage more often had lobar cerebral microbleeds (CMBs; 77%) than those without (36%; RR 2.5, 95% CI 1.1-5.7) and a higher number of lobar CMBs (patients with contrast leakage: median 2, IQR 1-8 versus those without: median 0, IQR 0-2; p = 0.02). This study shows that contrast leakage distant from the hematoma is common in days to weeks after spontaneous ICH. It is located predominantly cortical and related to lobar CMBs and therefore possibly to cerebral amyloid angiopathy.

Predictors of localization, outcome, and etiology of spontaneous intracerebral hemorrhages: focus on cerebral amyloid angiopathy. J Neural Transm (Vienna) 2020; 127:963-972.

Abstract
Despite its clinical relevance, cerebral amyloid angiopathy (CAA) is underdiagnosed worldwide. This retrospective study aimed to assess the incidence, etiology, predictors, and outcome of intracerebral hemorrhages (ICHs) in this region, with special focus on possible underlying CAA. Database screening of acute cares with intracranial hemorrhage diagnosis within 01/07/2014–01/07/2018 were conducted analyzing medical records and imaging. Spontaneous ICHs were classified as deep (basal ganglionic/thalamic/brainstem) and lobar/cerebellar (i.e., CAA-compatible) ICHs. Probable/definite CAA was established using the modified Boston criteria in a subgroup with ‘complete’ radiological/neuropathological work-up. The ability of several factors to discriminate between deep and lobar/cerebellar ICHs, between probable/definite CAA and non-probable CAA cases, and to predict 1-month case fatality was assessed. Of the 213 ICHs identified, 121 were in deep and 92 in lobar/cerebellar localization. Sub-analysis of 47 lobar/cerebellar ICHs with ‘complete’ work-up identified 16 probable/definite CAA patients, yielding an estimated 14.7% prevalence of CAA-related ICHs. Chronic hypertension was the most prevalent risk factor for all types of ICHs (including CAA-related), with hypertensive excess and younger age being independent predictors of deep whereas antiplatelet use of lobar/cerebellar localization. The 1-month case fatality was 33.8%, driven predominantly by age and INR > 1.4. Probable/definite CAA diagnosis was independently predicted by age, prior intracranial hemorrhage, and antiplatelet use. First in this region and among the few in the literature, this study reports a remarkable prevalence of CAA-related ICHs, emphasizing the need for an increased awareness of CAA and its therapeutic implications, especially regarding antiplatelets among the elderly.

Abstract
OBJECTIVE The aim of the present study was to identify incidences and prognostic factors for 30-day mortality of hemorrhagic strokes (HS) and divide them into intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). METHODS This retrospective cohort study was conducted using medical records of patients who underwent surgery due to HS, between January 2013 and April 2017, at Chiang Mai University Hospital, a large tertiary referral center, in Northern Thailand. 30-day mortality was followed after surgery. Prognostic factors included patients' characteristics, and clinical date related to early death, were determined. Data analysis was performed using Cox's proportional hazards model. RESULTS 460 patients were enrolled. The 30-day mortality rate was 8.8% and 12.3%, in ICH and SAH patients, respectively. Multivariable analyses demonstrated that the prognostic factors of early mortality in ICH patients were age 65-70 years (Adjusted HR 3.10 (95%CI 1.14-8.41)), >70 years (Adj.HR 2.64 (95%CI 1.09-6.36)) and hypertension (HT) (Adj.HR 2.98 (95%CI 1.25-7.12)). In SAH patients, prognostic factors were HT (Adj.HR 7.32 (95%CI 2.12-25.29)), and atrial fibrillation (AF) (Adj.HR 5.48 (95% CI 1.57-19.09)). CONCLUSIONS Ages over 65 years and HT were an important predictor of 30-day mortality in a subgroup of ICH patients, whereas HT and AF were significant prognostic factors in SAH. To reduce early death, management for stroke cases needed to take into account the specifics for older age patients with HT, and AF.

Abstract
OBJECTIVE To assess the association of cortical superficial siderosis (cSS) presence and extent with future bleeding risk in cerebral amyloid angiopathy (CAA). METHODS This was a meta-analysis of clinical cohorts of symptomatic patients with CAA who had T2*-MRI at baseline and clinical follow-up for future intracerebral hemorrhage (ICH). We pooled data in a 2-stage meta-analysis using random effects models. Covariate-adjusted hazard ratios (adjHR) from multivariable Cox proportional hazard models were used. RESULTS We included data from 6 eligible studies (n = 1,239). cSS pooled prevalence was 34% (95% confidence interval [CI] 26%-41%; I 2 87.94%; p < 0.001): focal cSS prevalence was 14% (95% CI 12%-16%; I 2 6.75%; p = 0.37), and disseminated cSS prevalence was 20% (95% CI 13%-26%; I 2 90.39%; p < 0.001). During a mean follow-up of 3.1 years (range 1-4 years), 162/1,239 patients experienced a symptomatic ICH-pooled incidence rate 6.9% per year (95% CI 3.9%-9.8% per year; I 2 83%; p < 0.001). ICH incidence rates per year according to cSS status were 3.9% (95% CI 1.7%-6.1%; I 2 70%; p = 0.018) for patients without cSS, 11.1% (95% CI 7%-15.2%; I 2 56.8%; p = 0.074) for cSS presence, 9.1% (95% CI 5.5%-12.8%; I 2 0%; p = 0.994) for focal cSS, and 12.5% (95% CI 5.3%-19.7%; I 2 73.2%; p = 0.011) for disseminated cSS. In adjusted pooled analysis, any cSS presence was independently associated with increased future ICH risk (adjHR 2.14; 95% CI 1.19-3.85; p < 0.0001). Focal cSS was linked with ICH risk (adjHR 2.11; 95% CI 1.31-2.41; p = 0.002), while disseminated cSS conferred the strongest bleeding risk (adjHR 4.28; 95% CI 2.91-6.30; p < 0.0001). CONCLUSION In patients with CAA, cSS presence and extent are the most important MRI prognostic risk factors for future ICH, likely useful in treatment planning. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that in symptomatic CAA survivors with baseline T2*-MRI, cSS (particularly if disseminated, i.e., affecting >3 sulci) increases the risk of future ICH.

Abstract
Background and Purpose- Hematoma location within the cerebellum may help identify the dominant small vessel disease type (cerebral amyloid angiopathy [CAA] versus nonamyloid small vessel disease). However, it is unknown whether this holds true for cerebral microbleeds (CMBs) within the cerebellum. We tested the hypothesis that cerebellar CMBs restricted to the cortex and vermis (defined as superficial regions) are associated with clinically diagnosed and pathology-verified CAA. Methods- Three hundred and seven consecutive spontaneous intracerebral hemorrhage (ICH) patients with a baseline magnetic resonance imaging that included susceptibility-weighted imaging or angiography were enrolled. Using a topographical template, cerebellar CMB patterns were defined as strictly superficial versus deep (cerebellar gray nuclei and white matter) or mixed (both regions involved). Thirty-six ICH patients with cerebellar CMBs and neuropathology data available were evaluated for the presence of CAA. Results- One hundred and thirty-five (44%) ICH patients had CMBs in the cerebellum. In the patient group with cerebellar CMBs, 85 (63%) showed a superficial pattern, and 50 (37%) had a deep/mixed pattern. Strictly superficial cerebellar CMBs were independently associated with a supratentorial pattern of probable CAA-ICH according to the Boston criteria (odds ratio, 1.6; CI, 1.03-2.5) and deep/mixed cerebellar CMBs with a pattern of deep/mixed ICH (odds ratio, 1.8; CI, 1.2-2.7). Pathologically verified CAA was present in 23 of 24 (96%) patients with superficial cerebellar CMBs versus 3 of 12 (25%) patients with deep/mixed cerebellar CMBs ( P<0.001). Conclusions- In ICH patients, cerebellar CMBs are relatively common and often restricted to superficial regions. A strictly superficial distribution of cerebellar CMBs is associated with clinically diagnosed and pathologically verified CAA.

Abstract
BACKGROUND AND PURPOSE Numerous studies have investigated the influence of meteorologic factors and seasons on the incidence of spontaneous intracerebral hemorrhage (ICH) with ambiguous results. In the present study, data from a large, international multicenter trial in patients with ICH were used to identify seasonal and meteorologic determinants for hypertensive-ICH with greater applicability. METHODS Patients were grouped according to the presumptive ICH cause, that is, hypertensive when located in the basal ganglia brain stem as well as cerebellum and nonhypertensive when located lobar. Both groups were compared with regard to air temperature and air pressure and their occurrence during the year. A regression analysis was performed to identify independent predictors of hypertensive-ICH. RESULTS Only hypertensive-ICH showed a seasonal pattern and occurred with higher air pressure values and at younger age. Independent predictors of hypertensive-ICH were increased air pressure on the actual day of the event and younger age as well as higher temperature. CONCLUSIONS In the present study with an international cohort, besides age air pressure, more than temperature, had an influence on the occurrence of hypertensive-ICH, only.

Abstract
BACKGROUND Acupuncture, especially acupuncture treatment on head for acute intracerebral hemorrhage (ICH), has long been disputable. The aim of this study was to evaluate the efficacy and safety of penetration acupuncture on head in patients with acute ICH. METHODS Eighty-two patients with acute ICH were randomized to receive penetration acupuncture treatment on head combined with conventional treatment (treatment group [TG]) or conventional treatment only (control group [CG]). Acupuncture treatments were given in 24 sessions over 4 weeks, with 3-month follow-up period. Measures included Clinical Neurological Function Deficit Scale (CNFDS), Barthel Index (BI), vital signs (respiration, heart rate, blood pressure, and oxygen saturation), and hematoma absorption ratio. RESULTS Both groups showed a progressively improvement in CNFDS and BI scores from day 7 to 90. The TG showed a significantly greater improvement in CNFDS than CG over time (P < 0.05). However, BI failed to show significant difference between the 2 groups (P > 0.05). The vital signs were stable and no expansion of hematoma occurred over the course of acupuncture treatment. CONCLUSION Penetration acupuncture treatment on head appeared to be safe over the course of treatment on acute ICH and may result in additional functional improvements detected in the CNFDS but not reflected in the BI. A larger-scale clinical trial with longer follow-up assessments is required to confirm these findings.

Abstract
About half of patients survive intracerebral hemorrhage (ICH), but most are left with significant disability. Rehabilitation after ICH is the mainstay of treatment to reduce impairment, improve independence in activities, and return patients to meaningful participation in the community. The authors discuss the neuroplastic mechanisms underlying recovery in ICH, preclinical and clinical interventional studies to augment recovery, and the rehabilitative and medical management of post-ICH patients.

Abstract
A stroke, or a cerebrovascular accident (CVA) is a life-threatening condition which often results in permanent or significant disability in the adult population. Several classifications of CVAs exist, one of them being based on the mechanism of injury of brain tissue: ischemic (85-90%) and hemorrhagic (10-15%). In a hemorrhagic stroke an intercranial bleeding occurs, leading to the formation of a focal hematoma typically located in the basal ganglia of the brain (approx. 45% of cases). A common yet underestimated cause of intracerebral hemorrhage is cerebral small vessel disease with microhemorrhages, including the cerebral amyloid angiopathy (CAA). This condition is associated with the deposition of amyloid-beta in arterial walls (in soft meninges, subcortical areas and the cerebral cortex). Research has shown that causes of hemorrhagic changes in the brain include genetic disorders, such as Down syndrome. The association is caused by the so-called 'gene dosage effect', as the gene for the precursor protein for amyloid-beta is located in chromosome 21. We wish to present the case of a 60 year old patient with Down syndrome who suffered a hemorrhagic stroke without antecedent hypertension. Based on the history taken, diagnostic imaging and the source literature, a diagnosis of cerebral amyloid angiopathy as the source of the bleeding was made (however it must be noted that without a full post-mortem examination, the Boston criteria allow only for a 'probable cerebral amyloid angiopathy' diagnosis to be made). The authors hereby also report the need to modify the Boston criteria for cerebral amyloid angiopathy.

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
Ethnicity and socioeconomic factors can influence disease susceptibility, clinical presentation, and outcome. We investigated the clinical characteristics (age, sex, seasonal variation, lesion site, symptoms, complications, prognosis, and sequelae) and risk factors for intracerebral hemorrhage (ICH) in 266 cases treated at our hospital in Hangzhou City, China, from January 2011 to December 2011. Risk of ICH increased dramatically with age; only 4.3% of cases were <30 years old, while 44.4% were >60 years of age. Men outnumbered women by 2:1 (67.3% vs. 32.7%). Single hemorrhage was most often located in the cerebral lobes (37.2% of cases), basal ganglia (34.2%), thalamus (8.3%), cerebellum (6.8%), ventricle (1.5%), and brainstem (1.1%), while 10.9% of cases exhibited hemorrhages at multiple sites. Hypertension was also a major risk factor for ICH, as 47% of all patients were hypertensive and the percentage increased with age. In hypertensive patients, the most common hemorrhage site was the basal ganglia and ICH was often associated with thrombopenia. In patients with leukemia (all forms), most hemorrhages were lobar. Warfarin- and encephalic operation-associated ICHs were all lobar. Headache was the major symptom of occipital, temporal, and frontal lobe hemorrhage. Dizziness, nausea, and vomiting were the major symptoms of cerebellum hemorrhage. Limb dysfunction was the major symptom of thalamic and basal ganglia hemorrhage. Disturbed level of consciousness was the major symptom in multisite, ventricular, parietal lobe, and brainstem hemorrhage. Hyperspasmia occurred most often in lobar hemorrhage and blurred vision in occipital lobe hemorrhage. Hospital mortality was 24.4% (n=65) with a mean delay from presentation to death of (10.5±18.5) d. The majority of fatalities were cerebral hernia cases (58.5%) and these patients also had the shortest time to death [(2.9±3.5) d]. Mortality was 100% in brainstem ICH and hemorrhagic conversion of cerebral infarct. Thrombopenia-associated ICH also had a high mortality rate (81.0%), while patients with cerebrovascular malformations and cerebral aneurysms demonstrated a much better prognosis (46.2% recovery).

Abstract
Intracerebral hemorrhage (ICH) remains a major medical problem, for which there is no effective treatment. However, extensive experimental and clinical research carried out in recent years has brought to light new exciting ideas for novel potential treatments. First, it was well documented that the management of hypertension helps to prevent new and recurrent ICH. Also, development of new guidelines for management of hypertension after the onset of the ICH may help in more effective ICH treatment. Existing contemporary data collected from preclinical studies indicates that ICH-induced inflammation represents a key factor leading to secondary brain damage, suggesting that some anti-inflammatory approaches can be used to treat hemorrhagic stroke. In this article, beyond discussing implications related to hypertension, we will summarize important (but not all) new discoveries connecting the role of inflammation to ICH pathology. Selected aspects of inflammatory response including the role of cytokines, transcription factor nuclear factor-kB, microglia activation, astrogliosis, and complement activation will be introduced. We will also discuss the role for reactive oxygen species and metalloproteinases in ICH pathogenesis and introduce basic knowledge on the nature of ICH-induced cell death including apoptosis. Potential targets for intervention and translation will be discussed.

Abstract
Cerebral Amyloidal Angiopathy (CAA), which occurs sporadically in most cases but can also occur hereditarily, belongs to the group amyloidoses and is characterized by the deposition and accumulation of beta-amyloid (Aβ) in smaller arterial vessels of the brain. The deposition of Aβ leads to degenerative changes in the cerebral vessel system (thickening of the vessel wall, microaneurysm, constriction of vascular lumen, dissection), which favour the development of the clinical symptomatology most often associated with CAA. Besides haemorrhages, cerebral ischaemia, transient neurological symptoms, leukoencephalopathy as well as cognitive decline and even dementia may appear in connection with CAA. A definite diagnosis of CAA can only be made on the basis of a pathological assessment, even though diagnostic findings of cerebral neuroimaging and clinical symptoms allow the diagnosis of a probable CAA. At present, no causal therapy options are available. Although CAA is placed within the range of neurological illnesses, psychiatric symptoms such as cognitive impairment, personality change or behavioural problems as well as depression are plausible clinical manifestations of CAA and may even dominate the clinical picture. Apart from epidemiological, pathogenetical, clinical and diagnostical aspects, possible psychiatric implications of CAA are discussed in the review article.

Abstract
Introduction Studies suggest that ethnicity and racial factors has an important role in the variation in epidemiology of stroke. The present study was conducted to assess the subtypes, risk factors, and outcome of stroke in the tribal community of Jharkhand state and to compare it with that in the non-tribals from the same geographical location. Methods We carried out a hospital-based prospective observational study at Rajendra Institute of Medical Sciences-Ranchi. Patients of acute stroke, reporting to the medical outpatient department and emergency department from January 1, 2006 to December 31, 2010 were studied. Computed tomography scan was done immediately and again after 24 h to confirm the diagnosis of stroke. To compare the findings between tribal and non-tribal patients, we used chi-square test/Fisher exact test as appropriate. Results Of the total 1156 patients included in the study, 536 were tribals, while 620 were non-tribals. Significant differences were found in tribal stroke patients as compared with non-tribals: mean age of tribal subjects was 53·8 years (60·8 years in non-tribals); stroke in young individual was present in 25% of tribal subjects (17% in non-tribals, P = 0·01); primary intracerebral hemorrhage variety was present in 31% of tribals (18% in non-tribals, P-value < 0·001); the 28th day case fatality rate was 43% among tribal subjects (35% among non-tribals, P = 0·02). Hypertension and alcohol abuse was found to be associated with intracerebral hemorrhage in tribal subjects, although no such association was found in non-tribals. Conclusion Tribals have early onset, poor outcomes and higher proportion of ICH compared to non-tribals. [Correction added after online publication 7 Aug 2012: The sentence ‘Tribals have early with non-tribals.’ in the Conclusion section of the abstract was deleted.]

Clin Pract 2012; 2:e56.

Abstract
The aim of this study was to present the data of a large cohort of patients with spontaneous supratentorial intracerebral hemorrhage (ICH), who were treated in our department and give a current overview considering special clinical characteristics, performed therapy and different predictive factors for morbidity and mortality. We reviewed the data of all patients with spontaneous ICH, who were treated in our department in a time span of 11 years through an analysis of our prospective database. Patients with spontaneous supratentorial ICH were included in the study. Patients with hemorrhage associated to vascular malformation or to cerebral ischemic stroke were excluded. The clinical performance at time of admission and discharge were scored using the Glasgow coma scale (GCS) and the Glasgow outcome scale (GOS) respectively. The patients' cohort was divided into surgically and conservatively treated groups. Statistical analysis [Analysis of Variance (ANOVA) and χ2-test] was done for various parameters to analyze their impact on morbidity and mortality. In total, we analyzed the data of 817 patients (364 female and 453 male). Two hundred and sixty-nine patients (32%) were treated conservatively and 556 patients (68%) underwent surgical procedures, i.e. cerebrospinal fluid drainage in 110 (19.8%), craniotomy in 338 (60.7%) and application of both methods in 108 patients (19.4%). Total mortality rate was estimated with 23.5%. GCS<8, age over 70 years, intraventricular and basal ganglia hemorrhage, coumadin medication, combination of co-morbidities, hypertensive hemorrhage and postoperative re-bleeding were statistically significant risk factors for worse outcome (GOS 1 and 2) in the operated group. Similar to the observations of the operated group, GCS<8, age over 70 years and coumadin medication were statistically significant for worse outcome in the conservative group. In contrast, lobar plus basal ganglia ICH and multi-lobar hemorrhages were the most significant factors for worse outcome in the conservative group. The results of our study show that ICH remains a multifarious disease and challenges neurosurgeons repeatedly. Selection of the treatment modality and prediction for neurofunc-tional outcome underlies various parameters. Treatment recommendations of ICH remain an unsolved issue. The consideration of the GCS grade at admission is the most important predictive factor. Old age is not an absolute contraindication for surgery, but cumulative multi-morbidity, especially cerebrovascular and cardiovascular diseases and oral anticoagulant therapy should be regarded critically in view of surgical treatment.

Abstract
BACKGROUND AIMS When a severe neurologic lesion occurs as a consequence of intracerebral hemorrhage (ICH), there is no effective treatment available for improving the outcome. However, cell therapy has opened new perspectives on reducing neurologic sequels subsequent to this disease. METHODS In this study, ICH was induced by stereotactic injection of 0.5 U collagenase type IV in the striatum of adult Wistar rats, and 2 h later a group of animals (n = 48) was subjected to intracerebral injection of 2 × 10(6) allogeneic bone marrow stromal cells (BMSC), while a control group (n = 48) received saline only. Eight animals from each group were killed at 48 h, 72 h, 7 days, 14 days, 21 days and 28 days. At these time-points, endogenous neurogenesis and survival of transplanted BMSC were studied. RESULTS Our findings show that after allogeneic BMSC transplantation, donor cells can survive in the brain tissue expressing neuronal and astroglial markers. Furthermore, BMSC transplantation enhances endogenous neurogenesis and inhibits apoptosis of newborn neural cells. CONCLUSIONS Although these results should be extrapolated to human disease with caution, it is obvious that cell therapy using allogeneic BMSC transplantation offers great promise for developing novel and efficacious strategies in patients suffering ICH.

Abstract
Intracerebral hemorrhage (ICH) imparts a higher mortality and morbidity than ischemic stroke. The therapeutic interventions that are currently available focus mainly on supportive care and secondary prevention. There is a paucity of evidence to support any one acute intervention that improves functional outcome. This chapter highlights current treatment targets for ICH based on the pathophysiology of the disease.

Abstract
Intracerebral haemorrhage accounts for 10%-15% of all strokes; however it has a poor prognosis with higher rates of morbidity and mortality. Neurological deterioration is often observed during the first hours after onset and determines poor prognosis. Intracerebral haemorrhage, therefore, is a neurological emergency which must be diagnosed and treated properly as soon as possible. In this guide we review the diagnostic procedures and factors that influence the prognosis of patients with intracerebral haemorrhage and we establish recommendations for the therapeutic strategy, systematic diagnosis, acute treatment and secondary prevention for this condition.

Abstract
BACKGROUND The optimal diagnostic evaluation for spontaneous intracerebral hemorrhage (ICH) remains controversial. In this retrospective study, we assessed the utility of early magnetic resonance imaging (MRI) in ICH diagnosis and management. METHODS Eighty-nine (72%) of 123 patients with spontaneous ICH underwent a brain CT and MRI within 30 days of ICH onset. Seventy patients with a mean age of 62 ± 15 years were included. A stroke neurologist and a general neurologist, each blinded to the final diagnosis, independently reviewed the admission data and the initial head CT and then assigned a presumed ICH cause under 1 of 9 categories. ICH cause was potentially modified after subsequent MRI review. The final 'gold standard' ICH etiology was determined after review of the complete medical record by an independent investigator. Change in diagnostic category and confidence and the potential impact on patient management were systematically recorded. RESULTS Mean time to MRI was 3 ± 5 days. Final ICH diagnosis was hypertension or cerebral amyloid angiopathy (CAA) in 50% of patients. After MRI review the stroke neurologist changed diagnostic category in 14%, diagnostic confidence in an additional 23% and management in 20%, and the general neurologist did so in 19, 21 and 21% of patients, respectively. MRI yield was highest in ICH secondary to ischemic stroke, CAA, vascular malformations and neoplasms, and did not differ by age, history of hypertension, hematoma location or the presence of intraventricular hemorrhage. CONCLUSIONS The results of this study suggest potential additive clinical benefit of early MRI in patients with spontaneous ICH.

Abstract
BACKGROUND The combination of an increase in aged population and adaptation of Western lifestyle is modifying the epidemiological status of intracerebral hemorrhage in China. The purpose of this study is to analyse and characterize the changing trends of intracerebral hemorrhage in Chongqing, the largest city in Southwest China, over the past 10 years. METHODS We retrospectively reviewed the medical records of patients diagnosed with intracerebral hemorrhage who visited the First Affiliated Hospital of Chongqing Medical University from 1 January 1998 to 31 December 1998 and from 1 January 2008 to 31 December 2008, respectively. Relevant variable information of these two populations for the two time periods was compared and discussed. RESULTS There were a total of 404 intracerebral hemorrhage patients who met the study criteria and registered in the First Affiliated Hospital in 1998 (128 cases) and 2008 (276 cases). The highest incidence of intracerebral hemorrhage was noted in the 1960s and 1970s age groups. The mean onset age of intracerebral hemorrhage was 2·65 years older in 2008 compared to 1998, specifically 2·10 years older for men and 3·38 years for women. In 1998, male intracerebral hemorrhage patients outnumbered female patients (1·42:1). This gender disproportion became higher in 2008 (1·63:1). Hypertension accounts for the highest proportion of all risk factors. The number of patients had minimally invasive interventions (intracranial hematoma drainage) was increased, and the in-hospital mortality rate decreased to 14·13% in 2008 from 19·53% in 1998. CONCLUSIONS We identified changes in population characteristics of patients with intracerebral hemorrhage during a period of economic development in China. These changes in patterns of intracerebral hemorrhage have raised new challenges and the needs for priority adjustment in the campaign for intracerebral hemorrhage prevention in China and other developing countries.

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
Stroke is the culmination of a heterogeneous group of cerebrovascular diseases that is manifested as ischemia or hemorrhage of one or more blood vessels of the brain. The occurrence of many acute cardiovascular events--such as myocardial infarction, sudden cardiac death, pulmonary embolism, critical limb ischemia, and aortic aneurysm rupture--exhibits prominent 24 h patterning, with a major morning peak and secondary early evening peak. The incidence of stroke exhibits the same 24 h pattern. Although ischemic and hemorrhagic strokes are different entities and are characterized by different pathophysiological mechanisms, they share an identical double-peak 24 h pattern. A constellation of endogenous circadian rhythms and exogenous cyclic factors are involved. The staging of the circadian rhythms in vascular tone, coagulative balance, and blood pressure plus temporal patterns in posture, physical activity, emotional stress, and medication effects play central and/or triggering roles. Features of the circadian rhythm of blood pressure, in terms of their chronic and acute effects on cerebral vessels, and of coagulation are especially important. Clinical medicine has been most concerned with the prevention of stroke in the morning, when population-based studies show it is of greatest risk during the 24 h; however, improved protection of at-risk patients against stroke in the early evening, the second most vulnerable time of cerebrovascular accidents, has received relatively little attention thus far.

Abstract
Primary intracerebral hemorrhage (ICH) results from spontaneous rupture of an intracranial vessel and is associated with high rates of early mortality and long-term morbidity. No surgical or medical intervention has been demonstrated to improve outcome. Acute blood pressure elevation is seen in the majority of patients with ICH and is correlated with poor outcome. Potential, but unproven, mechanisms for this association include facilitation of hematoma expansion as well as perihematomal edema growth. Conversely, the perihematomal region has also been hypothesized to have ischemic properties. Therefore, management of blood pressure in the acute phase lends itself to two competing rationales and the optimal target blood pressure remains unknown. A number of parenchymal and blood-flow imaging techniques have been utilized to improve our understanding of blood flow and metabolism in acute ICH. These studies generally indicate that ischemia is not a major pathophysiological mechanism of secondary injury in ICH. Ultimately, randomized, controlled trials, which are underway, will be required to definitively determine the safety and efficacy of acute blood pressure reduction. It appears most likely that earlier and more aggressive treatment of acute blood pressure will be recommended in the future.

Abstract
BACKGROUND AND PURPOSE This review focuses on the emerging principles of intracerebral hemorrhage (ICH) management, emphasizing the natural history and treatment of intraventricular hemorrhage. The translational and clinical findings from recent randomized clinical trials are defined and discussed. Summary of Review- Brain hemorrhage is the most severe of the major stroke subtypes. Extension of the hemorrhage into the ventricles (a 40% occurrence) can happen early or late in the sequence of events. Epidemiological data demonstrate the amount of blood in the ventricles relates directly to the degree of injury and likelihood of survival. Secondary tissue injury processes related to intraventricular bleeding can be reversed by removal of clot in animals. Specific benefits of removal include limitation of inflammation, edema, and cell death, as well as restoration of cerebral spinal fluid flow, intracranial pressure homeostasis, improved consciousness, and shortening of intensive care unit stay. Limited clinical knowledge exists about the benefits of intraventricular hemorrhage (IVH) removal in humans, because organized attempts to remove blood have not been undertaken in large clinical trials on a generalized scale. New tools to evaluate the volume and location of IVH and to test the benefits/risks of removal have been used in the clinical domain. Initial efforts are encouraging that increased survival and functional improvement can be achieved. Little controversy exists regarding the need to scientifically investigate treatment of this severity factor. CONCLUSIONS Animal models demonstrate clot removal can improve the acute and long-term consequences of intraventricular extension from intracerebral hemorrhage by using minimally invasive techniques coupled to recombinant tissue plasminogen activator-mediated clot lysis. The most recent human clinical trials show that severity of initial injury and the long-term consequences of blood extending into the ventricles are clearly related to the amount of bleeding into the ventricular system. The failure of the last 2 pivotal brain hemorrhage randomized control trials may well relate to the consequences of intraventricular bleeding. Small proof of concept studies, meta-analyses, and preliminary pharmacokinetics studies support the idea of positive shifts in mortality and morbidity, if this 1 critical disease severity factor, IVH, is properly addressed. Understanding clinical methods for the removal of IVH is required if survival and long-term functional outcome of brain hemorrhage is to improve worldwide.

Abstract
BACKGROUND In Norway, there are approximately 16000 strokes each year and 15% of these are caused by intracerebral hematomas. Intracerebral hemorrhage (ICH) results from the rupture of blood vessels within the brain parenchyma. ICH occurs as a complication of several diseases, the most prevalent of which is chronic hypertension. When hemorrhage develops in the absence of a pre-existing vascular malformation or brain parenchymal lesion, it is denoted primary ICH. Secondary ICH refers to hemorrhage complicating a pre-existing lesion. Primary ICH is the most common type of hemorrhagic stroke, accounting for approximately 10% of all strokes. Despite aggressive management strategies, the 30-day mortality remains high, at almost 50%, with the majority of deaths occurring within the first 2 days. At 6 months, only 20-30% achieve independent status. MATERIAL AND METHODS This article is based on clinical experience, modern therapeutic guidelines for the treatment of intracerebral hematomas and up-to-date medical literature found in Medline. The article discusses the pathophysiology, clinical aspects, treatment, and the prognosis of intracerebral hematomas. RESULTS AND DISCUSSION Advances in diagnosis, prognosis, pathophysiology, and treatment over the past few decades have significantly advanced our knowledge of ICH; however, much work still needs to be carried out. Future genetic and epidemiologic studies will help identify at-risk populations and hopefully allow for primary prevention. Randomized controlled studies focusing on novel therapeutics should help to minimize secondary injury and hopefully improve morbidity and mortality.

Abstract
BACKGROUND Stroke is a major cause of morbidity and mortality in Qatar. OBJECTIVES The aim of our study was to determine types of strokes, the associated risk factors, clinical presentation, outcome, and time to hospital admission among Qatari and non-Qatari patients as well as young and nonyoung patients. METHODS We conducted a hospital-based prospective observational study including all patients admitted to Hamad Medical Corporation with first-ever stroke from September 15, 2004, to September 14, 2005. A stroke was defined according to World Health Organization criteria. RESULTS Stroke was confirmed in 270 patients of whom 217 (80.4%) had ischemic stroke and 53 (19.6%) had hemorrhagic stroke. Male patients predominated in all types of stroke. The main risk factors for stroke were hypertension and diabetes, whereas lacunar infarct was the most common subtype of ischemic stroke. Risk factor profiles were similar between Qatari and non-Qatari patients except for hypercholesterolemia, which was observed with a higher frequency in Qatari compared with non-Qatari patients with ischemic stroke. There were significant differences between the young and nonyoung patients with ischemic stroke with respect to risk factors, ejection fraction, ventricular wall-motion abnormalities, time to hospital admission, and outcome. Most patients arrived at the hospital more than 3 hours from stroke onset because of unawareness of stroke symptoms. The overall in-hospital mortality was 9.3%. CONCLUSIONS Hypertension and diabetes mellitus were the main risk factors for stroke in Qatar, whereas lacunar infarct was the most common subtype. Significant differences between the young and nonyoung patients were observed with respect to risk factors, ejection fraction, ventricular wall-motion abnormalities, time to hospital admission, and outcome.

Abstract
✓ Intracerebral hemorrhage (ICH), for which no effective treatment strategy is currently available, constitutes one of the most devastating forms of stroke. As a result, developing therapeutic options for ICH is of great interest to the medical community. The 3 potential therapies that have the most promise are cell replacement therapy, enhancing endogenous repair mechanisms, and utilizing various neuroprotective drugs. Replacement of damaged cells and restoration of function can be accomplished by transplantation of cells derived from different sources, such as embryonic or somatic stem cells, umbilical cord blood, and genetically modified cell lines. Early experimental data showing the benefits of cell transplantation on functional recovery after ICH have been promising. Nevertheless, several studies have focused on another therapeutic avenue, investigating novel ways to activate and direct endogenous repair mechanisms in the central nervous system, through exposure to specific neuronal growth factors or by inactivating inhibitory molecules. Lastly, neuroprotective drugs may offer an additional tool for improving neuronal survival in the perihematomal area. However, a number of scientific issues must be addressed before these experimental techniques can be translated into clinical therapy. In this review, the authors outline the recent advances in the basic science of treatment strategies for ICH.

Abstract
BACKGROUND The number of persons reaching the age 80 years and over is increasing in most populations. Literature focusing on hypertensive intracerebral hemorrhage (ICH) in this age group is lacking. Therefore, we aimed to analyze the main clinical characteristics of ICH of the advanced old age, in the context of hypertension. METHODS From 1999 to 2003 we studied 56 hypertensive very elderly patients presenting with ICH (50% women; age 80-99 years). As controls, 168 hypertensive gender-matched persons with ICH, aged <80 years, were randomly selected by a 3:1 factor for clinical comparisons. RESULTS Compared with their younger counterparts, the very elderly patients had a trend for fewer cases of obesity (34 vs. 49%, p = 0.05) and diabetes mellitus (12 vs. 24%, p = 0.06), had lower systolic, diastolic and mean blood pressure measures (in all, p < 0.01) and more cases with hematoma extension into ventricles (p = 0.02). Thalamic hemorrhage was more frequent in the very elderly patients than in controls (43 vs. 28%, p = 0.04). In multivariate analysis, age, Glasgow coma scale score at hospital admission, ICH volume and infratentorial location were independent predictors of in-hospital mortality, in all persons combined. In the very elderly group exclusively, Glasgow coma scale score was the only factor independently associated with mortality. CONCLUSIONS ICH occurring in hypertensive patients aged > or =80 years has several differences from that seen in younger people; however, these differences do not seem to impact on early outcome.

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
OBJECTIVE To identify determinants of early outcome in spontaneous lobar hemorrhage. MATERIALS AND METHODS From 2500 acute stroke patients included in a prospective hospital-based stroke registry over a 12-year period, 97 cases of lobar hematoma were selected. Determinants of in-hospital mortality were studied in multiple regression models. RESULTS Lobar hematomas accounted for 3.9% of all acute stroke patients and 35.9% of intracerebral hemorrhages. The presence of chronic obstructive pulmonary disease (COPD) was a significant predictive variable in the model based on demographic variables and vascular risk factors [odds ratio (OR): 17.18; 95% CI: 1.77-166.22] and in the model based on these variables plus clinical data (OR: 15.12; 95% CI: 1.27-179.59). Other predictive variables included altered consciousness, previous cerebral infarct and chronic liver disease. CONCLUSIONS COPD appeared as the most important predictor of death during hospitalization after lobar cerebral hemorrhage, a finding not generally acknowledged earlier.
