Abstract
Angiographically negative subarachnoid hemorrhage (anSAH) has traditionally been considered a benign condition, mainly because of favorable outcomes in the acute stage in comparison to the often negative acute outcomes of aneurysmal subarachnoid hemorrhage. However, a growing body of research in recent years shows that anSAH often leads to cognitive impairments, emotional distress, and difficulties in resuming work or other daily life activities. Therefore, in this position paper, we call for a change in neurological care and a shift in patient communication, emphasizing the importance of addressing patient needs and fostering realistic expectations rather than solely focusing on the benign nature of the condition.

Front Neurol 2024; 15:1301197. [PMID: 38333609 PMCID: PMC10851875 DOI: 10.3389/fneur.2024.1301197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Accepted: 01/10/2024] [Indexed: 02/10/2024] Open
Abstract
Background Hyponatremia is a common electrolyte disturbance in patients with neurological disease; however, its predictive role for outcome in patients with supratentorial spontaneous intracerebral hemorrhage (sICH) is controversial. This study aims to explore the association between hyponatremia within 7 days after bleeding and 90-day mortality in patients with supratentorial sICH. Methods A retrospective analysis was conducted at our institution. Patients with sICH meeting the inclusion criteria were enrolled in this study. Multivariate regression analyses were performed to determine the predictive value of hyponatremia (serum sodium <135 mmol/L) for 90-day mortality and functional outcome. Subgroup analysis was performed based on the degree and duration of hyponatremia and therapeutic strategies. The Spearman correlation test was performed to explore the relationship between hyponatremia severity and duration with variables in a multivariate regression model. Kaplan-Meier curve was depicted to reveal the relationship between hyponatremia and mortality. The receiver operating characteristic (ROC) curve was plotted to show the diagnostic effect of the minimum concentration of serum sodium (sodiummin) on 90-day mortality. Results A total of 960 patients were enrolled, 19.6% (188) of whom were patients with hyponatremia and 26.0% (250) had 90-day mortality. The incidence of hyponatremia was roughly 2.5 times in non-survivors compared with survivors (34.8% vs. 14.2%). Multivariate regression analysis revealed that hyponatremia was the independent predictor of 90-day mortality (OR 2.763, 95%CI 1.836-4.157) and adverse outcome (OR 3.579, 95%CI 2.332-6.780). Subgroup analysis indicated an increased trend in mortality risk with both duration (more or less than 48 h) and severity of hyponatremia (mild, moderate, and severe) and confirmed the predictive value of hyponatremia for mortality in patients undergoing surgical intervention (external ventricular drainage, craniotomy, and decompressive craniectomy; all p < 0.05). The Spearman correlation test indicated no moderate or strong relationship between hyponatremia severity and duration with other variables in the multivariate model (all |rs| < 0.4). The ROC curve suggested the moderate diagnostic performance of sodiummin for mortality in both general patients and subgroups of therapeutic method patients (AUC from 0.6475 to 0.7384). Conclusion Hyponatremia occurring in the first 7 days after bleeding is an independent predictor of 90-day morality and adverse outcome. Rigorous electrolyte scrutiny in patients treated surgically is required.

Abstract
PURPOSE Individuals with non-traumatic subarachnoid haemorrhage (SAH) are often excluded from studies of stroke populations due to differing pathophysiology and treatment pathways. Thus, aphasia presentation in the non-traumatic SAH population is potentially under-represented within existing research evidence. MATERIALS AND METHODS Five databases were systematically searched with terms related to "aphasia" and "subarachnoid haemorrhage." Studies were included if aphasia was attributed to non-traumatic SAH or its associated complications, and where at least one language assessment measure used determined the presence or absence of aphasia. Study quality was evaluated using the Mixed Methods Appraisal Tool (MMAT). RESULTS Following deduplication, 2726 articles were identified for title and abstract screening. Full text screening for 162 articles occurred, with 18 articles selected for inclusion. Aphasia incidence ranged from 5 to 24%, and was influenced by assessment measure, timing of assessment, subgroup studied, and classifications of aphasia. Many studies excluded participants with poorer clinical outcome, intracerebral complications, or severe aphasia. Few studies used comprehensive language assessment measures to examine across language domains. CONCLUSIONS Aphasia presentation is highly heterogenous following non-traumatic SAH. Future research using comprehensive language assessments at multiple time points post onset is required to better understand aphasia presentation and management needs for this population.

Abstract
Introduction Survivors of an acute subarachnoid hemorrhage (aSAH) may suffer from a long-term neurological disability, cognitive impairment, anxiety, and depression, which can also be related to post-intensive care syndrome (PICS). The aim of this study was to examine the prevalence of PICS symptoms in post-intensive care (ICU) aftercare aSAH patients. Methods We conducted an observational cohort study in aSAH patients from a post-ICU aftercare clinic (ICU-AC). PICS symptoms were evaluated using the Impact of Event Scale-Revised (IES-R), Hospital Anxiety and Depression Scale (HADS), and a medical questionnaire for physical and cognitive functioning. Results A total of 110 patients were included. The prevalence of anxiety and depressive symptoms was 23.6% and 19.1%, respectively. Post-traumatic stress disorder (PTSD) was seen in 26.4%. Cognitive complaints were lack of concentration (63.6%), short-term memory loss (45.8%), and reduced speed of thinking (60.9%). The most reported physical complaints were fatigue (73.6%), limitations in daily activity (72.7%), muscle weakness (41.8%), pain (36.4%), and weight loss (30.9%). PICS symptoms related to all three domains were present in 30% of patients. Conclusion The prevalence of PICS in patients after aSAH is high. Even in patients without aSAH-related neurological impairment who were discharged home, a high prevalence of PICS symptoms was reported. Early screening for PICS should comprise all three domains and is important to facilitate a better tailored rehabilitation of these patients.

J Neurol Sci 2023; 446:120566. [PMID: 36731357 DOI: 10.1016/j.jns.2023.120566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 01/17/2023] [Accepted: 01/22/2023] [Indexed: 01/26/2023]
Abstract
BACKGROUND External ventricular drainage (EVD) for acute hydrocephalus after aneurysmal subarachnoid haemorrhage (aSAH) carries a risk of complications. We studied the proportion of patients in whom EVD can be avoided by treating acute hydrocephalus with ≥1 lumbar punctures (LP). METHODS From a prospectively collected database, we retrieved data on all aSAH patients admitted between 2007 and 2017 who developed acute hydrocephalus (i.e. neurological deterioration and ventricular enlargement <72 h after aSAH). Our regime is to consider LP as initial treatment. We calculated the proportions of patients (with corresponding 95% confidence interval (CI)) who improved after the initial LP and the extent of clinical improvement, the proportions of patients who were treated with only ≥1 LP(s), and those of patients needing continuous external ventricular or external lumbar drainage, or permanent ventriculoperitoneal or lumboperitoneal drainage. RESULTS Of 1391 consecutive aSAH patients, 473 (34%) had acute hydrocephalus, of whom 388 (82%) were treated. Of the 86 patients with LP as initial treatment, 70 (81% [95% CI 72-88]) showed initial improvement (with increase in median Glasgow Coma Score from 10 (IQR 7-12) to 12 (IQR 9-14) after initial LP), 39 (45% [95% CI 35-56]) improved with LP only, 41 (48% [95% CI 37-58]) needed continuous drainage and six (7% [95% CI 3-14]) needed permanent drainage. CONCLUSION Around half the patients treated with LP for deterioration from acute hydrocephalus after aSAH does not require continuous extraventicular or extralumbar drainage.

Predicting Shunt Dependency from the Effect of Cerebrospinal Fluid Drainage on Ventricular Size. Neurocrit Care 2022; 37:670-677.

Abstract
BACKGROUND Prolonged external ventricular drainage (EVD) in patients with subarachnoid hemorrhage (SAH) leads to morbidity, whereas early removal can have untoward effects related to recurrent hydrocephalus. A metric to help determine the optimal time for EVD removal or ventriculoperitoneal shunt (VPS) placement would be beneficial in preventing the prolonged, unnecessary use of EVD. This study aimed to identify whether dynamics of cerebrospinal fluid (CSF) biometrics can temporally predict VPS dependency after SAH. METHODS This was a retrospective analysis of a prospective, single-center, observational study of patients with aneurysmal SAH who required EVD placement for hydrocephalus. Patients were divided into VPS-dependent (VPS+) and non-VPS dependent groups. We measured the bicaudate index (BCI) on all available computed tomography scans and calculated the change over time (ΔBCI). We analyzed the relationship of ΔBCI with CSF output by using Pearson's correlation. A k-nearest neighbor model of the relationship between ΔBCI and CSF output was computed to classify VPS. RESULTS Fifty-eight patients met inclusion criteria. CSF output was significantly higher in the VPS+ group in the 7 days post EVD placement. There was a negative correlation between delta BCI and CSF output in the VPS+ group (negative delta BCI means ventricles become smaller) and a positive correlation in the VPS- group starting from days four to six after EVD placement (p < 0.05). A weighted k-nearest neighbor model for classification had a sensitivity of 0.75, a specificity of 0.70, and an area under the receiver operating characteristic curve of 0.80. CONCLUSIONS The correlation of ΔBCI and CSF output is a reliable intraindividual biometric for VPS dependency after SAH as early as days four to six after EVD placement. Our machine learning model leverages this relationship between ΔBCI and cumulative CSF output to predict VPS dependency. Early knowledge of VPS dependency could be studied to reduce EVD duration in many centers (intensive care unit length of stay).

Clinical Factors Contributing to Cognitive Function in the Acute Stage after Treatment of Intracranial Aneurysms: A Cross-Sectional Study. J Clin Med 2022; 11:jcm11175053. [PMID: 36078981 PMCID: PMC9457194 DOI: 10.3390/jcm11175053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 08/21/2022] [Accepted: 08/24/2022] [Indexed: 11/25/2022] Open
Abstract
Background: The factors affecting cognitive function after treatment of subarachnoid haemorrhage (SAH) can be categorised into aneurysmal factors, procedural factors, and complications. The aim of this study was to investigate which of these factors has greater influence on the cognitive function. Methods: We retrospectively identified 14 patients with unruptured intracranial aneurysms (UIAs) and 34 patients with SAH with mild symptoms at disease onset (Hunt and Hess grade: >3). All patients underwent neuropsychological tests within 35 days of discharge from hospitalisation for treatment. The relationship between the clinical factors and each neuropsychological test score was evaluated using multiple linear regression analysis after controlling for age and years of education. Results: Patients with UIA showed greater cognitive impairment in visual memory and the frontal/executive domains. Hypertension was associated with cognitive impairment. Patients with SAH showed greater cognitive impairment in the visuospatial, verbal memory, and frontal/executive domains. The dome-to-neck ratio, aneurysms located in the posterior circulation, microsurgical clipping, procedure time, anaesthesia duration, and complications were associated with cognitive impairment. Conclusions: Underlying diseases, procedural factors, and complications contributed to cognitive impairment after treatment of intracranial aneurysms. Since the effect of each factor on each cognitive domain was slightly different, a more in-depth study of these effects is needed.

Aneurysmal subarachnoid hemorrhage survivors show long-term deficits in spatial reference memory in a pilot study of a virtual water maze paradigm. Clin Neurol Neurosurg 2021; 207:106788.

Abstract
BACKGROUND Limited data exists on the long-term effects of aneurysmal subarachnoid hemorrhage (SAH) on spatial memory. Herein, we used a computerized virtual water maze to evaluate the feasibility of spatial memory testing in pilot cohort of ten patients who survived previous SAH. METHODS Ten SAH survivors (5.8 ± 5.1 years after initial hemorrhage) and 7 age-matched controls underwent testing in a virtual water maze computer program. Additional subgroup analyses were performed to evaluate spatial reference memory correlation for ventricular size on admission, placement of an external ventricular drain and placement of a shunt. RESULTS With respect to the spatial memory acquisition phase, there was no significant difference of pathway length traveled to reach the platform between SAH survivors and control subjects. During the probe trial, control subjects spent significantly longer time in target quadrants compared to SAH survivors (F(3, 24) = 10.32, p = 0.0001; Target vs. Right: Mean percent difference 0.16 [0-0.32], p = 0.045; Target vs. Across: Mean percent difference 0.35 [0.19-0.51], p < 0.0001; Target vs. Left: Mean percent difference 0.21 [0.05-0.37], p = 0.0094). Furthermore, patients who initially presented with smaller ventricles performed worse that those patients who had ventriculomegaly and/or required surgical management of hydrocephalus. CONCLUSIONS Our data demonstrate that SAH survivors have persistent spatial reference memory deficits years after the hemorrhage. Hydrocephalus at presentation and external ventricular drainage were not found to be associated with poor spatial memory outcomes in this pilot cohort. Therefore, other causes such as global cerebral edema or magnitude of initial ICP spike, need to be considered to be examined as root cause as well in subsequent studies. The protocol described in this manuscript is able to demonstrate a spatial reference memory deficit and can be used to study risk factors for spatial memory impairment on a larger scale.

Abstract
Methods Prospective study included 40 cases with acute aSAH. Initial evaluation by Glasgow Coma Scale (GCS) and the severity of aSAH was detected by both the clinical Hunt and Hess and radiological Fisher's grading scales. TCD was done for all patients five times within 10 days measuring the mean flow velocities (MFVs) of cerebral arteries. At the 3-month follow-up, patients were classified into two groups according to Montreal Cognitive Assessment (MoCA) scale: the first group was 31 cases (77.5%) with intact cognitive functions and the other group was 9 cases (22.5%) with impaired cognition. Results Patients with impaired cognitive functions showed significantly lower mean GCS (p = 0.03), significantly higher mean Hunt and Hess scale grades (p = 0.04), significantly higher mean diabetes mellitus (DM) (p = 0.03), significantly higher mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) (p = 0.02 and p = 0.005, respectively), and significantly higher MFVs measured within the first 10 days. The patients with cognitive impairment were accompanied by a higher incidence of hydrocephalus (p = 0.01) and a higher incidence of delayed cerebral ischemia (DCI) (p < 0.001). Logistic regression analysis detected that MFV ≥ 86 cm/s in the middle cerebral artery (MCA), MFV ≥ 68 cm/s in the anterior cerebral artery (ACA), and MFV ≥ 45 cm/s in the posterior cerebral artery (PCA) were significantly associated with increased risk of cognitive impairment. Conclusion Cognitive impairment after the 3-month follow-up phase in aSAH patients was 22.5%. Acute hydrocephalus and DCI are highly associated with poor cognitive function in aSAH. Increased MFV is a strong predictor for poor cognitive function in aSAH. This trial is registered with NCT04329208.

Abstract
Background Detecting and treating neuropsychological deficits after aneurysmatic subarachnoid hemorrhage (aSAH) play a key role in regaining independence; however, detecting deficits relevant to social and professional reintegration has been difficult and optimal timing of assessments remains unclear. Therefore, we evaluated the feasibility of administering the Neuropsychological Assessment Battery screening module (NAB-S) to patients with aSAH, assessed its value in predicting the ability to return to work and characterized clinical as well as neuropsychological recovery over the period of 24 months. Methods A total of 104 consecutive patients treated for aSAH were recruited. After acute treatment, follow up visits were conducted at 3, 12 and 24 months after the hemorrhage. NAB-S, Montreal Cognitive Assessment (MoCA) and physical examination were performed at each follow up visit. Results The NAB-S could be administered to 64.9, 75.9 and 88.9% of the patients at 3, 12 and 24 months, respectively. Moderate impairment of two or more neuropsychological domains (e.g speech, executive function, etc.) significantly correlated with inability to return to work at 12 and 24 months as well as poor outcome assessed by the extended Glasgow Outcome Scale (GOSE) at 3, 12 and 24 months. The number of patients with favorable outcomes significantly increased from 25.5% at discharge to 56.5 and 57.1% at 3 and 12 months, respectively, and further increased to 74.1% after 24 months. Conclusion The NAB-S can be administered to the majority of patients with aSAH and can effectively detect clinically relevant neuropsychological deficits. Clinical recovery after aSAH continues for at least 24 months after the hemorrhage which should be considered in the design of future clinical trials.

Abstract
BACKGROUND AND PURPOSE Current guidelines do not support the routine use of corticosteroids in patients with aneurysmal subarachnoid hemorrhage (aSAH). However, corticosteroids use in aSAH has been practiced at some centers by convention. The aim of the study was to determine the incidence of hydrocephalus requiring ventriculoperitoneal shunt (VPS) placement as well as functional outcome on discharge and adverse events attributed to corticosteroids in patients with aSAH treated with different dexamethasone (DXM) treatment schemes. METHODS We retrospectively analyzed 206 patients with aSAH stratified to three groups based on the DXM treatment scheme: no corticosteroids, short course of DXM (S-DXM; 4 mg every 6 h for 1 day followed by a daily total dose reduction by 25% and then by 50% on last day), and long course of DXM (L-DXM; 4 mg every 6 h for 5-7 days followed by reduction by 50% every other day). The primary outcome measure was the placement of a VPS, and the secondary outcome was a good functional outcome [modified Rankin Scale (mRS) 0-3] at hospital discharge. Safety measures were the incidence of infection (pneumonia, urinary tract infection, ventriculitis, meningitis), presence of delirium, and hyperglycemia. RESULTS There was no difference in the rate of external ventricular drain (EVD) (p = 0.164) and VPS placement (p = 0.792), nor in the rate of good outcome (p = 0.928) among three defined treatment regimens. Moreover, the median duration of treatment with EVD did not differ between subjects treated with no corticosteroids, S-DXM, and L-DXM (p = 0.905), and the probability of EVD removal was similar when stratified according to treatment regimens (log-rank; p = 0.256). Patients who received L-DXM had significantly more complications as compared to patients, who received no corticosteroids or S-DXM (78.4% vs. 58.6%; p = 0.005). After adjustment, L-DXM remained independently associated with increased risk of combined adverse events (OR = 2.72; 95%CI, 1.30-5.72; p = 0.008), infection (OR = 3.45; 95%CI, 1.63-7.30; p = 0.001) and hyperglycemia (OR = 2.05; 95%CI, 1.04-4.04; p = 0.039). CONCLUSIONS DXM use among patients with aSAH did not relate to the rate of EVD and VPS placement, duration of EVD treatment, and functional disability at discharge but increased the risk of medical complications.

Abstract
Only a handful of published reports exist today that describe neurological complications following smoke inhalation injury. In this study, we characterize acute pathophysiological changes in the brain of sheep exposed to smoke inhalation, with- and without third-degree skin burn that models the injuries sustained by human victims of fire accidents. Blood-brain barrier integrity and hemorrhage were analyzed throughout the brain using specific histological stains: Hematoxylin & Eosin, Luxol fast blue, Periodic acid-Schiff (PAS), and Martius, Scarlet and Blue (MSB). Our data show that, following smoke inhalation injury, alone and in combination with third-degree skin burn, there was a significant increase in the number of congested and dilated blood vessels in the frontal cortex, basal ganglia, amygdala, hippocampus, pons, cerebellum, and pituitary gland as compared to sham-injured controls. Positive PAS staining confirmed damage to the basement membrane of congested and dilated blood vessels throughout the brain. Severe rupturing of blood vessels, microvascular hemorrhaging and bleeding throughout the brain was also observed in the injured groups. No significant changes in hemodynamics and PaO2 were observed. Our data demonstrate for the first time that acute smoke inhalation alone results in diffuse blood-brain barrier dysfunction and massive bleeding in the brain in the absence of hypoxia and changes in hemodynamics. These findings provide critical information and prompt further mechanistic and interventional studies necessary to develop effective and novel treatments aimed at alleviating CNS dysfunction in patients with smoke and burn injuries.

Cognitive impairment in angiographically negative subarachnoid haemorrhage: A case-matched prospective study 1-year post-incident. Cortex 2020; 128:49-60.

Abstract
INTRODUCTION Few studies investigate cognitive outcomes in patients with angiographically negative subarachnoid haemorrhage (anSAH), which is traditionally viewed as a condition with an excellent prognosis. The aim of this study was to assess neuropsychological outcomes in a prospective cohort of anSAH patients 1-year post-event. METHOD This prospective case-controlled study of cognitive function in patients with anSAH (n = 38) recruited from the national centre for neurosurgery and compared matched controls (n = 28). The cognitive battery assessed memory, executive function, attention, visuo-spatial function, processing speed, social cognition, language, and mood. Patients were matched to controls on age, education, and premorbid intelligence. RESULTS Multivariate Analysis of Variance (MANOVA) were used. Patients performed significantly worse than controls on all cognitive domain composite scores. anSAH patients had a higher frequency of impairment within encoding, executive, and processing speed domains when compared to healthy controls. Discriminant Function Analysis (DFA) indicated high sensitivity and specificity to detect cognitive impairment between groups. CONCLUSION Although the majority of patients with anSAH make an excellent physical recovery, our data show a high rate of cognitive dysfunction in patients 1-year post-incident. Cognitive impairment in anSAH is not a universal feature, and its manifestations may be more heterogeneous than previously recognised. Some impairment may be mediated by impaired speed of processing which negatively influences other cognitive domains. The profile of cognitive impairment supports a neurotoxicity hypothesis, which suggests that blood in the subarachnoid space, rather than the bleed per se, results in a diffuse pattern of cognitive deficits.

Abstract
Subarachnoid hemorrhage (SAH) is a devastating stroke type. Approximately 50% of survivors suffer from the permanent disability, caused by the cognitive deficits. To enrich the pre-clinical research on the neurological deficits after SAH, we investigate the temporal cognitive deficits and the longitudinal course of cognitive recovery in endovascular perforation SAH murine model. The SAH mice show reproducible body weakness and headache-symbolized moaning symptoms, which is closed to clinical patients. SAH mice exhibit significantly impaired cognitive function in domains of learning ability, short-term and long-term memory. The cognitive deficits occur mostly in the early phase and recover gradually till day 10 after SAH. The systematical assessments of cognitive function after experimental aneurysmal SAH elucidate the time course of cognitive deficits and provide the time window of potential interventions.

Abstract
BACKGROUND Cognitive dysfunction is the most common form of neurological impairment after aneurysmal subarachnoid hemorrhage (aSAH) in the chronic phase. Cognitive deficits in the acute phase after aSAH, however, remain scarcely investigated. The aim of the present study was to test cognitive function and to identify medical predictors of cognitive deficits in the acute phase of aSAH. METHODS Prospective study including 51 patients treated for aSAH. Patients were treated in accordance with a standardized institutional protocol and subjected to neuropsychological evaluation around discharge from neurosurgical care. The neuropsychological test results were transformed into a global cognitive impairment index where an index value of 0.00 is considered normal and 1.00 is considered maximally pathological. Patients with an index score of less than 0.75 were considered having good global cognitive function while those with an index score equal to or above 0.75 were considered having poor global cognitive function. Univariate and multiple regression analysis were used to identify medical predictors of cognitive function. RESULTS Fifty-seven percent of the patients had poor cognitive function. They showed severe cognitive deficits, with most tests falling well below two standard deviations from the expected normal mean. Poor cognitive function was not reflected in a poor modified Rankin score in almost half of the cases. Patients with good cognitive function showed only mild cognitive deficits with most tests falling only slightly below the normal mean. Delayed memory was the most affected function in both groups. Univariate analysis identified acute hydrocephalus and aSAH-acquired cerebral infarction to be predictors of poor cognitive function. Cerebrospinal fluid drainage in excess of 2000 ml six-folded the risk of poor cognitive function, whereas a new cerebral infarction 11-folded the respective risk of poor cognitive function. CONCLUSION More than half of aSAH patients have severe cognitive deficits in the acute phase. The modified Rankin Score should be combined with neuropsychological screening in the acute phase after aSAH to get a more accurate description of the patients' disabilities. Acute hydrocephalus and aSAH-acquired cerebral infarction are the strongest predictors of poor cognitive function in the acute phase.

Abstract
OBJECTIVE Occlusive treatment of posterior communicating artery (PCoA) aneurysms has been seen as a fairly uncomplicated procedure. The objective here was to determine the radiological and clinical outcome of patients after PCoA aneurysm rupture and treatment and to evaluate the risk factors for impaired outcome. METHODS In a retrospective clinical follow-up study, data were collected from 620 consecutive patients who had been treated for ruptured PCoA aneurysms at a single center between 1980 and 2014. The follow-up was a minimum of 1 year after treatment or until death. RESULTS Of the 620 patients, 83% were treated with microsurgical clipping, 8% with endovascular coiling, 2% with the two procedures combined, 1% with indirect surgical methods, and 6% with conservative methods. The most common procedural complications were treatment-related brain infarctions (15%). The occurrence of artery occlusions (10% microsurgical, 8% endovascular) was higher than expected. Most patients made a good recovery at 1 year after aneurysmal subarachnoid hemorrhage (modified Rankin Scale [mRS] score 0-2: 386 patients [62%]). A fairly small proportion of patients were left severely disabled (mRS score 4-5: 27 patients [4%]). Among all patients, 20% died during the 1st year. Independent risk factors for an unfavorable outcome, according to the multivariable analysis, were poor preoperative clinical condition, intracerebral or subdural hematoma due to aneurysm rupture, age over 65 years, artery occlusion on postoperative angiography, occlusive treatment-related ischemia, delayed cerebral vasospasm, and hydrocephalus requiring a shunt. CONCLUSIONS Even though most patients made a good recovery after PCoA aneurysm rupture and treatment during the 1st year, the occlusive treatment-related complications were higher than expected and caused morbidity even among initially good-grade patients. Occlusive treatment of ruptured PCoA aneurysms seems to be a high-risk procedure, even in a high-volume neurovascular center.

Abstract
BACKGROUND Cognitive sequelae frequently follow subarachnoid hemorrhage (SAH) and include deficits across multiple domains of executive function. This factor affects overall functional outcomes negatively, especially in younger patients. Several clinical correlates predict development and severity of cognitive dysfunction after SAH. Hypothetical mechanisms of cognitive dysfunction in the absence of radiographic lesion include cerebral hypoperfusion and blood breakdown products, resulting in perturbed interneuronal communication and network synchrony, excitotoxicity, and altered microRNA expression. METHODS The PubMed database was searched for articles discussing cognitive outcomes in patients with unruptured and ruptured intracranial aneurysmal disease, sequelae of treatment, and modalities for neuropsychologic testing. RESULTS Treatment of unruptured intracranial aneurysms, although capable of preventing SAH, comes with its own set of complications and may also affect cognitive function. Neuropsychological tests such as the Montreal Cognitive Assessment, Mini-Mental Status Examination, and others have proved useful in evaluating cognitive decline. Studies using functional neurologic imaging modalities have identified regions with altered activation patterns during various cognitive tasks. The sum of research efforts in this field has provided useful insights and an initial understanding of cognitive dysfunction after aneurysm treatment and SAH that should prove useful in guiding and rendering future investigations more fruitful. CONCLUSIONS Development of finer and more sensitive neuropsychological tests in evaluating the different domains of cognitive function after aneurysm treatment and SAH in general will be useful in accurately determining outcomes after ictus and comparing efficacy of different therapeutic strategies.

Abstract
BACKGROUND The prevalence of hypothalamic-pituitary dysfunction after aneurysmal subarachnoid hemorrhage has not been precisely determined, and conflicting results have been reported in the literature. OBJECTIVE To perform a systematic review and meta-analysis investigating the prevalence of pituitary insufficiency after aneurysmal subarachnoid hemorrhage and to focus on basal serum and dynamic test differences. METHODS The prevalence of pituitary dysfunction was quantified at 3 to 6 months and >6 months after aneurysmal subarachnoid hemorrhage. Proportions were transformed with the logit transformation. A subgroup analysis was performed focusing on the differences in outcome between basal serum and dynamic tests for the diagnosis of growth hormone deficiency (GHD) and secondary adrenal insufficiency. RESULTS Overall prevalence of hypopituitarism differed considerably between studies, ranging from 0.05 to 0.45 in studies performed between 3 and 6 months after the event and from 0 to 0.55 in long-term studies (>6 months), with pooled frequencies of 0.31 (95% confidence interval [CI]: 0.22-0.43) and 0.25 (95% CI: 0.16-0.36), respectively. Pooled frequency of GHD at 3 to 6 months was 0.14 (95% CI: 0.08-0.24). At >6 months, GHD prevalence was 0.19 (95% CI: 0.13-0.26) overall, but ranged from 0.15 (95% CI: 0.06-0.33) with the insulin tolerance test to 0.25 (95% CI: 0.15-0.36) using the growth hormone releasing hormone + arginine test. CONCLUSION Hypopituitarism is a common complication in patients with aneurysmal subarachnoid hemorrhage, with GHD being the most prevalent diagnosis. We showed that variations in prevalence rates in the literature are partly due to methodological differences among pituitary function tests.

Abstract
Cognitive impairment is a major factor contributing to poor functional outcome after subarachnoid hemorrhage caused by a ruptured cerebral aneurysm (aSAH). Montreal Cognitive Assessment (MoCA) has been shown to be superior to the Mini-Mental State Examination in screening for cognitive domain deficit and correlating to functional outcome in aSAH patients. The aim of the current study was to determine the Montreal Cognitive Assessment (MoCA) score change that was associated with change of health in general in an aSAH patient cohort. We recruited aSAH patients from a regional neurosurgical center over a 3-year period. Patient assessments including MoCA and global rating of change (GRoC) were carried out at at 3 and 12months after aSAH. Anchor-based and distribution-based approaches were adopted to calculate the Minimum Clinically Important Difference (MID). One hundred and seventy-five aSAH patients completed both 3-month and 1-year assessments and consented for participation. Employing the distribution-based approach for the 3-month and 1-year MoCA scores, the MID estimates equated to a change of 2.0 and 1.1 respectively. Employing the anchor-based approach (with GRoC), the MID estimate of MoCA (median, IQR) was 2, 1-4. In conclusion, we found that the MID of MoCA score associated with change of health in general in aSAH patients was 2. The MID provides guidance for future clinical trial design targeting on cognitive dysfunction after aSAH.

Abstract
Background and Purpose—
Shunt dependent hydrocephalus after aneurysmal subarachnoid hemorrhage (aSAH) is a common sequela that may lead to poor neurological outcome and predisposes to various interventions, admissions, and complications. We reviewed post-aSAH shunt dependency in a population-based sample and tested the feasibility of a clinical risk score to identify subgroups of aSAH patients with increasing risk of shunting for hydrocephalus.
Methods—
A total of 1533 aSAH patients from the population-based Eastern Finland Saccular Intracranial Aneurysm Database (Kuopio, Finland) were used in a recursive partitioning analysis to identify risk factors for shunting after aSAH. The risk model was built and internally validated in random split cohorts. External validation was conducted on 946 aSAH patients from the Southwestern Tertiary Aneurysm Registry (Dallas, TX) and tested using receiver-operating characteristic curves.
Results—
Of all patients alive ≥14 days, 17.7% required permanent cerebrospinal fluid diversion. The recursive partitioning analysis defined 6 groups with successively increased risk for shunting. These groups also successively risk stratified functional outcome at 12 months, shunt complications, and time-to-shunt rates. The area under the curve–receiver-operating characteristic curve for the exploratory sample and internal validation sample was 0.82 and 0.78, respectively, with an external validation of 0.68.
Conclusions—
Shunt dependency after aSAH is associated with higher morbidity and mortality, and prediction modeling of shunt dependency is feasible with clinically useful yields. It is important to identify and understand the factors that increase risk for shunting and to eliminate or mitigate the reversible factors. The aSAH-PARAS Consortium (Aneurysmal Subarachnoid Hemorrhage Patients’ Risk Assessment for Shunting) has been initiated to pool the collective insights and resources to address key questions in post-aSAH shunt dependency to inform future aSAH treatment guidelines.

Abstract
PURPOSE Pituitary dysfunction is reported to be a common complication following aneurysmal subarachnoid hemorrhage (aSAH). The aim of this meta-analysis is to analyze the literature on clinical prevalence, risk factors and outcome impact of pituitary dysfunction after aSAH, and to assess the possible need for pituitary screening in aSAH patients. METHODS We performed a systematic review with meta-analysis based on a comprehensive search of four databases (PubMed/MEDLINE, ISI/Web of Science, Scopus and Google Scholar). RESULTS A total of 20 papers met criteria for inclusion. The prevalence of pituitary dysfunction in the acute phase (within the first 6 months after aSAH) was 49.30 % (95 % CI 41.6-56.9), decreasing in the chronic phase (after 6 months from aSAH) to 25.6 % (95 % CI 18.0-35.1). Abnormalities in basal hormonal levels were more frequent when compared to induction tests, and the prevalence of a single pituitary hormone dysregulation was more frequent than multiple pituitary hormone dysregulation. Increasing age was associated with a lower prevalence of endocrine dysfunction in the acute phase, and surgical treatment of the aneurysm (clipping) was related to a higher prevalence of single hormone dysfunction. The prevalence of pituitary dysfunction did not correlate with the outcome of the patient. CONCLUSIONS Neuroendocrine dysfunction is common after aSAH, but these abnormalities have not been shown to consistently impact outcome in the data available. There is a need for well-designed prospective studies to more precisely assess the incidence, clinical course, and outcome impact of pituitary dysfunction after aSAH.

Abstract
OBJECTIVES This research aimed to assess attention and executive functions in subarachnoid hemorrhage (SAH) patients. METHODS The prospective, controlled, longitudinal study was conducted. There were two groups of patients (SAH and lumbar microdiscectomy groups), and all of them were operated on by a single neurosurgeon (KD) in the same institution. Preoperatively, SAH patients were in the Hunt-Hess Grade I and II. They did not develop any focal neurological deficit or hydrocephalus postoperatively. The patients were tested in 2-time points: 15 and 45 days after microsurgery with a battery of tests and questioners consisting of the Trail Making Test, the Sustained Attention to Response Task, the Hayling Sentence Completion Test, The Attention/Concentration test of Attention, the Wechsler Adult Intelligence Scale (verbal part). Results between groups were compared (sex, age; years of education and verbal IQ). RESULTS It was found the presence of lower attention and executive function test scores in the SAH group of patients with a trend of improving during the time. CONCLUSION The detailed neuropsychological assessment of operated patients who sustained SAH and were without the focal neurological deficit postoperatively, showed declination in their attention and executive function with a trend of cognitive recovery as time passes by.

Abstract
BACKGROUND Acute hydrocephalus is a well-known sequela of aneurysmal subarachnoid hemorrhage (SAH). Controversy exists about whether open microsurgical methods serve to reduce shunt dependency compared with endovascular techniques. OBJECTIVE To determine predictors of shunt-dependent hydrocephalus and functional outcomes after aneurysmal SAH. METHODS A total of 471 patients who were part of a prospective, randomized, controlled trial from 2003 to 2007 were retrospectively reviewed. All variables including demographic data, medical history, treatment, imaging, and functional outcomes were included as part of the trial. No additional variables were retrospectively collected. RESULTS Ultimately, 147 patients (31.2%) required a ventriculoperitoneal shunt (VPS) in our series. Age, dissecting aneurysm type, ruptured vertebrobasilar aneurysm, Fisher grade, Hunt and Hess grade, admission intraventricular hemorrhage, admission intraparenchymal hemorrhage, blood in the fourth ventricle on admission, perioperative ventriculostomy, and hemicraniectomy were significant risk factors (P < .05) associated with shunt-dependent hydrocephalus on univariate analysis. On multivariate analysis, intraventricular hemorrhage and intraparenchymal hemorrhage were independent risk factors for shunt dependency (P < .05). Clipping vs coiling treatment was not statistically associated with VPS after SAH on both univariate and multivariate analyses. Patients who did not receive a VPS at discharge had higher Glasgow Outcome Scale and Barthel Index scores and were more likely to be functionally independent and to return to work 72 months after surgery (P < .05). CONCLUSION There is no difference in shunt dependency after SAH among patients treated by endovascular or microsurgical means. Patients in whom shunt-dependent hydrocephalus does not develop after SAH tend to have improved long-term functional outcomes.

Abstract
OBJECTIVE To associate the presence of language deficits with varying scores of the Fisher grading scale in patients with subarachnoid hemorrhage in the period preceding the treatment of aneurysm in the anterior circulation, as well as to compare the scores of this scale, identifying the grades more associated with the decline of language. METHODS Database analysis of 185 preoperative evaluations of language, through the Montreal Toulouse Protocol Alpha version and verbal fluency through CERAD battery, of patients from "Hospital da Restauração" with aneurysmal subarachnoid hemorrhage, divided according to the Fisher grading scale (Fisher I, II, III, or IV) and compared with a control group of individuals considered normal. RESULTS The various scores of the Fisher grading scale have different levels of language deficits, more pronounced as the amount of blood increases. Fisher III and IV scores are most associated with the decline of language. CONCLUSIONS Our study made it possible to obtain information not yet available in the literature, by correlating the various scores of the Fisher grading scale with language yet in the period preceding treatment.

Abstract
Background Memory declines measured by traditional tests in patients after subarachnoid hemorrhage (SAH) are well documented. Classic examinations of memory problems sometimes do not significantly correlate with memory functions in everyday life. The objective of the study was to assess the specific type of everyday memory loss in patients after microsurgical treatment of ruptured intracranial aneurysm causing SAH. Methods The prospective controlled, randomized study was conducted using the specific tests for everyday memory measure with high ecological validity. All patients were operated on by the same neurosurgeon (KD). Preoperatively, patients were in a good grade (Hunt-Hess I or II), with no neurological deficit and no hydrocephalus postoperatively. Patients were tested at two phases: 15 and 45 days after microsurgery with the Rivermead behavioral memory test (RBMT) and the cognitive failure questionnaire (CFQ). Results We compared the results of the tests administered in subjects that underwent microdiscectomy surgery for SAH to a control group that underwent surgery for lumbar disc herniation (DH). Conclusion Neuropsychological assessment of operated patients who sustained SAH showed a decline, compared to the DH group, in everyday memory function. Also, we found failures in perception and motor function in operated SAH patients with a trend of cognitive recovery as time progresses.

Abstract
Object
It is common practice to use a new contralateral bur hole for ventriculoperitoneal shunt (VPS) placement in subarachnoid hemorrhage (SAH) patients with an existing ventriculostomy. At Thomas Jefferson University and Jefferson Hospital for Neuroscience, the authors have primarily used the ventriculostomy site for the VPS. The purpose of this study was to compare the safety of the 2 techniques in patients with SAH.
Methods
The rates of VPS-related hemorrhage, infection, and proximal revision were compared between the 2 techniques in 523 patients undergoing VPS placement (same site in 464 and contralateral site in 59 patients).
Results
The rate of new VPS-related hemorrhage was significantly higher in the contralateral-site group (1.7%) than in the same-site group (0%; p = 0.006). The rate of VPS infection did not differ between the 2 groups (6.4% for same site vs 5.1% for contralateral site; p = 0.7). In multivariate analysis, higher Hunt and Hess grades (p = 0.05) and open versus endovascular treatment (p = 0.04) predicted shunt infection, but the VPS technique was not a predictive factor (p = 0.9). The rate of proximal shunt revision was 6% in the same-site group versus 8.5% in the contralateralsite group (p = 0.4). In multivariate analysis, open surgery was the only factor predicting proximal VPS revision (p = 0.05).
Conclusions
The results of this study suggest that the use of the ventriculostomy site for VPS placement may be feasible and safe and may not add morbidity (infection or need for revision) compared with the use of a fresh contralateral site. This rapid and simple technique also was associated with a lower risk of shunt-related hemorrhage. While both techniques appear to be feasible and safe, a definitive answer to the question of which technique is superior awaits a higher level of medical evidence.

Abstract
BACKGROUND Neuropsychological deficits (NPD) are common in patients with aneurysmal subarachnoid haemorrhage (aSAH). NPD are one of the major limiting factors for patients with an otherwise acceptable prognosis for sustained quality of life. There are only a few studies reporting outcome after aSAH, which used a standardized neuropsychological test battery as a primary or secondary outcome measure. Aim of this study was to determine the current practice of reporting NPD following aSAH in clinical studies. METHODS A MEDLINE analysis was performed using the search term "subarachnoid haemorrhage outcome". The latest 1,000 articles were screened. We recorded study design, number of patients, and the presence of neuropsychological outcome report. Additionally, the time of testing after aSAH, the neuropsychological tests administered, as well as the percentage of patients with NPD were analyzed. RESULTS A total of 324 publications between 2009 and 2012 were selected for further review. Of those, 21 studies (6.5%) reported neuropsychological outcome, in 2,001 of 346,666 patients (0.6%). The assessment of NPD differed broadly using both subjective and objective cognitive evaluation, and a large variety of tests were used. CONCLUSION Neuropsychological outcome is underreported, and there is great variety in assessment in currently published clinical articles on aSAH. Prospective randomized trials treating aSAH may benefit from implementing more comprehensive and standardized neuropsychological outcome measures. This approach might identify otherwise unnoticed treatment effects in future interventional studies of aSAH patients.

Abstract
BACKGROUND External ventricular drain (EVD) placement temporarily provides cerebrospinal fluid (CSF) diversion and is indicated in patients with aneurysmal subarachnoid hemorrhage (aSAH) to relieve hydrocephalus. METHODS Case report. RESULTS A 56-year-old woman was admitted to our hospital with aSAH complicated by acute hydrocephalus. An EVD was placed and set to 15 mmHg. After nearly 72 h, she clinically deteriorated. A computed tomography (CT) perfusion scan showed hypoperfusion in the watershed regions in both hemispheres and CT angiogram showed mild segmental arterial narrowings. After the EVD was lowered to 5 mmHg, the radiologic perfusion abnormalities and clinical symptoms resolved. CONCLUSIONS We postulate a mechanism by which CSF diversion could decrease the risk of delayed cerebral ischemia after aSAH: CSF drainage at low levels of intracranial pressure (e.g., 5 mmHg) could improve blood flow in the microcirculation, and thus improve tissue perfusion.

Abstract
Objective To evaluate characteristics of cognitive impairments according to the location of aneurysmal subarachnoid hemorrhage (SAH) using a computerized neuropsychological test (CNT). Method A total of 211 patients were transferred to our rehabilitation department after becoming neurologically stable following aneurysmal SAH. Twenty four of the 211 patients met the inclusion criteria and participated in a screening test using the mini-mental state examination (MMSE). Twenty patients with a MMSE score <26 were followed prospectively with a CNT and Beck depression inventory (BDI). Eleven patients had anterior communicating artery (ACoA) aneurysms and the other 9 had middle cerebral, internal carotid or posterior communicating artery aneurysms. Results There were no differences in age, education, Hunt and Hess grade, or Fisher grade between the patients with ACoA aneurysmal SAH compared to patients with other aneurysmal SAH. In patients with ACoA aneurysmal SAH, scores of BDI (p=0.020), verbal learning test were lower than those of other aneurysmal SAH patients. In contrast, patients with non-ACoA aneurysmal SAH took significantly more time in auditory (p=0.025) and visual continuous performance tests (p=0.028). The cognitive deficit following aneurysmal SAH could be characterized by its location using CNT. Conclusion Using CNT in aneurysmal SAH patients could be a useful tool for evaluating the characteristics of cognitive impairment and planning rehabilitation programs according to each characteristic.

Incidence of ventricular shunt placement for hydrocephalus with clipping versus coiling for ruptured and unruptured cerebral aneurysms in the Nationwide Inpatient Sample database: 2002 to 2007. World Neurosurg 2012; 76:548-54. [PMID: 22251503 DOI: 10.1016/j.wneu.2011.05.054] [Citation(s) in RCA: 60] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2010] [Revised: 05/16/2011] [Accepted: 05/26/2011] [Indexed: 01/29/2023]
Abstract
BACKGROUND Few studies have compared the incidence of ventricular shunt placement for hydrocephalus after clipping versus coiling of cerebral aneurysms. OBJECTIVE The Nationwide Inpatient Sample (NIS) database was used to compare, on a national level, the incidence of ventricular shunt placement after clipping versus coiling of ruptured and unruptured aneurysms. METHODS Hospitalizations for clipping and coiling of ruptured and unruptured aneurysms from 2002 to 2007 were collected from the NIS by cross-matching International Classification of Diseases-9 codes for diagnoses of subarachnoid hemorrhage or unruptured cerebral aneurysm with procedure codes for clipping or coiling. The incidence of ventricular shunt placement for hydrocephalus after clipping and coiling was compared using generalized linear models with generalized estimating equations (GEE) to adjust for patient- and hospital-specific factors and correlation between admissions. RESULTS Of 10,899 ruptured aneurysm patients (6593 clipping, 4306 coiling), clipping had a similar incidence of ventricular shunt placement (9.3%) compared to coiling (10.5%) (odds ratio = 0.984; 95% confidence interval = 0.85, -1.14; P value = 0.833 after adjustment for patient-specific and hospital-specific factors). Likewise, of 9686 unruptured aneurysm patients (4483 clipping, 5203 coiling), clipping had similar incidence of ventricular shunt placement (0.4%) compared to coiling (0.5%) (odds ratio = 0.763; 95% confidence interval = 0.37, -1.58; P value = 0.465 after adjustment for patient-specific and hospital-specific factors). Predictors of shunt placement in ruptured aneurysm patients were age, comorbidity score, admission type, payer, and hospital aneurysm volume. Predictors of shunt placement in unruptured aneurysm patients were comorbidity score and admission type. CONCLUSIONS In an observational study, clipping and coiling of ruptured and unruptured cerebral aneurysms are associated with similar incidences of ventricular shunt placement for hydrocephalus.

Abstract
Brain hemorrhage is the most fatal form of stroke and has the highest morbidity of any stroke subtype. Intraventricular extension of hemorrhage (IVH) is a particularly poor prognostic sign, with expected mortality between 50% and 80%. IVH is a significant and independent contributor to morbidity and mortality, yet therapy directed at ameliorating intraventricular clot has been limited. Conventional therapy centers on managing hypertension and intracranial pressure while correcting coagulopathy and avoiding complications such as rebleeding and hydrocephalus. Surgical therapy alone has not changed the natural history of the disease significantly. However, fibrinolysis in combination with extraventricular drainage shows promise as a technique to reduce intraventricular clot volume and to manage the concomitant complications of IVH.

Abstract
BACKGROUND AND PURPOSE The International Subarachnoid Aneurysm Trial (ISAT) reported lower rates of death and disability with endovascular versus neurosurgical treatment of ruptured intracranial aneurysms. However, assessment of functional outcome was limited to the modified Rankin Scale, which is known to be insensitive to cognitive function. A neuropsychological substudy (N-ISAT) was therefore done in all recruits from 8 ISAT centers in the United Kingdom. METHODS Detailed neuropsychological assessment was performed at a 12-month follow-up visit. Impairment was defined as performance below the 5th percentile of the study population on at least 2 tests in >or=2 major cognitive domains. Analysis was restricted to patients who were not known to be otherwise disabled according to the modified Rankin Scale (ie, modified Rankin Scale 0 to 2). RESULTS Of 836 patients randomized in ISAT in the 8 UK centers (411 allocated endovascular treatment versus 425 neurosurgery), 224 were dead or disabled before 12-month follow-up (78 allocated endovascular treatment versus 135 neurosurgery). Of the remaining 612 patients eligible for neuropsychological assessment, 137 (65 allocated endovascular treatment versus 72 neurosurgery) did not attend. Of the 474 nondisabled patients who were assessed, 152 (32.1%) had cognitive impairment. Patients with cognitive impairment had reduced self-reported health-related quality of life (P<0.001) in both treatment groups, but cognitive impairment was less common in those allocated endovascular treatment (70 of 262 versus 82 of 212 allocated neurosurgery, OR=0.58, 95% CI 0.38 to 0.87, P=0.0055). The incidence of epilepsy was also lower in the N-ISAT endovascular group (7 versus 18, OR=0.30, 0.11 to 0.77, P=0.005) but was independent of the effect on cognitive function. CONCLUSIONS Cognitive impairment occurred in approximately one third of patients who were not otherwise disabled according to the modified Rankin Scale in N-ISAT and was more frequent in the neurosurgery group. These results have implications for management of ruptured intracranial aneurysms and more generally for interpretation of the outcomes of clinical trials that use the modified Rankin Scale.

Abstract
BACKGROUND Patients with SAH often experience cognitive decline. Previous studies used normal volunteers, published normal test values, and orthopedic patients as controls to identify factors for postoperative cognitive decline. The present study excluded the effects of surgery by comparing cognitive function after surgical repair in patients with aneurysmal SAH and patients with unruptured intracranial aneurysm. METHODS This study recruited 117 patients with SAH due to ruptured aneurysm and 39 patients with incidentally found unruptured intracranial aneurysms. The cognitive test battery consisted of the Japanese translation of the WAIS-R, the Japanese translation of the WMS, and the recall trial of the ROCF. Postoperative neuropsychological test scores for the patients with SAH and control subjects were compared using group-rate and event-rate analysis. The relationship between clinical variable and postoperative cognitive decline in the patients with SAH was evaluated by univariate analysis using the Mann-Whitney U test or chi(2) test. RESULTS Group-rate analysis showed that the WAIS-R and ROCF scores were significantly lower in the SAH group than in the control group. Event-rate analysis demonstrated that the incidence of cognitive decline in the patients with SAH (73 [62.4%] of the 117 patients) was significantly higher than that in the control subjects (12 [30.8%] of 39 patients). The Hunt and Hess grade was significantly higher in patients with postoperative cognitive decline. CONCLUSION The cognitive function after SAH was significantly correlated with Hunt and Hess grade on admission when using patients with postoperative unruptured intracranial aneurysm as the control group.

Abstract
Abstract
OBJECTIVE
We sought to determine the frequency, risk factors, and impact on functional outcome and quality of life (QOL) of global cognitive impairment 1 year after subarachnoid hemorrhage.
METHODS
We prospectively evaluated global cognitive status 3 and 12 months after hospitalization with the Telephone Interview for Cognitive Status in 232 subarachnoid hemorrhage survivors. Cognitive impairment was defined as a score of 30 or less (scaled 0 = worst, 51 = best). Logistic regression was performed to calculate adjusted odds ratios (AORs) for impairment at 1 year. Basic activities of daily living were evaluated with the Barthel Index, instrumental activities of daily living were assessed with the Lawton scale, and QOL was evaluated with the Sickness Impact Profile.
RESULTS
The frequency of cognitive impairment was 27% at 3 months and 21% at 12 months. After the effects of age, education, and race/ethnicity were controlled for, risk factors for cognitive impairment at 12 months included anemia treated with transfusion (AOR, 3.4; P = 0.006), any temperature level higher than 38.6°C (AOR, 2.7; P = 0.016), and delayed cerebral ischemia (AOR, 3.6; P = 0.01). Among cognitively impaired patients at 3 months, improvement at 1 year occurred in 34% and was associated with more than 12 years of education and the absence of fever higher than 38.6°C during hospitalization (P = 0.015). Patients with cognitive impairment at 1 year had worse concurrent QOL and less ability to perform instrumental and basic activities of daily living (all P < 0.001).
CONCLUSION
Global cognitive impairment affects more than 20% of subarachnoid hemorrhage survivors at 1 year, is predicted by fever, anemia treated with transfusion, and delayed cerebral ischemia, and adversely affects functional recovery and QOL.

Abstract
Superficial siderosis (SS) of the central nervous system is a rare condition caused by chronic subarachnoid hemorrhage. Clinical manifestations typically include sensorineural hearing loss and cerebellar ataxia. Recurrent episodic encephalopathy in the setting of SS has not been reported. We describe a unique case of SS in a 67-year-old man with an 8-year history of episodic encephalopathy associated with headache and vomiting. The patient also had a history of progressive dementia, ataxia, and myelopathy. A diagnosis of superficial siderosis was made after magnetic resonance gradient-echo images showed diffuse hemosiderin staining over the cerebellum and cerebral convexities. No intracerebral source of hemorrhage was identified. The patient therefore underwent gadolinium-enhanced spinal MRI which suggested a possible vascular malformation. A therapeutic laminectomy subsequently confirmed an arteriovenous fistula which was resected. In SS, there are often long delays between symptom onset and definitive diagnosis. Early identification is facilitated by magnetic resonance imaging with gradient-echo sequences. When no source of hemorrhage is identified intracranially, then total spinal cord imaging is indicated to assess for an occult source of hemorrhage as occurred in our case.

Abstract
Object
In this study, the authors prospectively evaluated long-term psychosocial and neurocognitive performance in patients suffering from nonaneurysmal, nontraumatic subarachnoid hemorrhage (SAH) and investigated the association between the APOE-ε4 genotype and outcome in these patients.
Methods
All patients admitted to the authors' institution between January 2001 and January 2003 with spontaneous nonaneurysmal SAH were prospectively examined (mean follow-up 59.8 months). The APOE genotype was determined in all patients by polymerase chain reaction from a blood sample. Of the 30 patients included in this study, 11 were carriers of the ε4 allele.
Results
All patients showed a good recovery and regained full independence with no persisting neurological deficits. The patients with the ε4 allele, however, scored significantly higher on the Beck Depression Inventory (22.1 ± 6.3 vs 14.1 ± 5.1). At follow-up, depression was more persistent in the group with the ε4 allele compared with the group that lacked the allele. This finding reached statistical significance (p < 0.05). Selective attention was impaired in all patients during the first year of follow-up, with an earlier recovery noted in the patients without the ε4 allele. Moreover, there was a tendency toward a linear relationship between the Beck Depression Inventory and the d2 Test of Attention. Two patients who carried the ε4 allele did not return to their employment even after 5 years.
Conclusions
The findings in this study suggest that the APOE genotypes may be associated with the psychosocial and neurocognitive performance after spontaneous nonaneurysmal SAH, even in the absence of neurological impairment. Physicians should consider patient genotype in assessing the long-term consequences of nonaneurysmal SAH.

Abstract
This report presents a case of a 39-year-old male with a spontaneously ruptured frontotemporal dermoid cyst. Intraoperatively, during surgical resection of the cyst, significant fat spillage occurred associated with a profound anterior circulation vasospasm. The patient underwent serial neuropsychological evaluation over five months, revealing a profile of initial deterioration, followed by delayed recovery of cognitive function. A review of the literature reveals three other case reports describing ischemic deficit after dermoid rupture, but the cognitive impairment associated with this pathology has never been formally profiled before, and it may be possible to draw analogies to the well-established ischemic deficit post-subarachnoid hemorrhage found in the literature. Neuropsychological profiling additionally informs us about the nature and progression of this entity from a cognitive perspective and whether the etiology of deficit caused by dermoid rupture could be localized, or global, secondary to diffuse fatty dissemination in the CSF.

Abstract
Abstract
OBJECTIVE
The goals of this study were to investigate the risk factors, indications, complications, and outcome for patients with ventriculoperitoneal shunts (VPSs) after subarachnoid hemorrhage and to define a subgroup eligible for future prospective studies designed to clarify indications for placement of a VPS.
METHODS
Clinical characteristics of 236 prospectively evaluated patients with subarachnoid hemorrhage and 6 months of follow-up were analyzed. Hydrocephalus was estimated by the relative bicaudate index (RBCI) measured on computed tomographic scans at the time of shunting. Patients were divided into three groups by ventricle size: Group 1 included 121 patients with small ventricles (RBCI <1.0), Group 2 included 88 patients with borderline ventricle size (RBCI 1.0–1.4), and Group 3 included 27 patients with markedly enlarged ventricles (RBCI >1.4).
RESULTS
Initially, 86 patients (36%) underwent ventriculoperitoneal shunting: 19 in Group 1 (16%), 43 in Group 2 (49%), and 24 in Group 3 (90%). Indications for placement of a VPS, risk factors, and outcome differed markedly by group. Four patients (3% of those not initially shunted) developed delayed hydrocephalus requiring a VPS, including one in Group 2 (2%). The 6-month shunt complication rate was 13%. Evaluation of patients in Group 2 indicated that functional status was an important factor in selecting candidates for shunting, and that patients receiving shunts and shunt-free patients demonstrated improvement in functional status during follow-up.
CONCLUSION
Although we currently use a proactive shunting paradigm for posthemorrhagic hydrocephalus, this report demonstrates that a conservative approach to patients with borderline ventricle size (i.e., RBCI of 1.0–1.4) and normal intracranial pressure should be evaluated in a prospective randomized trial.

Abstract
OBJECTIVE We investigated early postoperative hemodynamic and metabolic values using positron emission tomography (PET) scanning in subarachnoid hemorrhage (SAH) patients treated with clipping or coiling, and evaluated usefulness of PET studies in predicting late ischemic events and neurological outcome in SAH patients. METHODS We examined 14 SAH patients treated with neurosurgical clipping (CLIP group) and 16 patients treated with endovascular coiling (COIL group). Cerebral blood flow (CBF), cerebral metabolic rate for oxygen (CMRO2), and oxygen extraction fraction (OEF) were determined using 15O-PET scanning about 8.5 days after SAH. RESULTS 1) Mean regional CBF (rCBF) in the middle cerebral artery (MCA) territory was significantly higher in CLIP group compared with COIL group; regional CMRO2 (rCMRO2) and regional OEF (rOEF) were also higher. Four clipped patients showed true hyperemia in the MCA territory; none of the coiled patients showed hyperemia. 2) Surgical intervention significantly decreased mean rCMRO2 and rOEF in the operated frontal lobe compared with the unoperated side. 3) Nine of 30 patients (40%) developed subsequent clinical vasospasm after SAH. Significant differences between the spasm group and non-spasm group were not observed in the MCA territory before vasospasm. CONCLUSION A wide range of cerebral perfusion patterns including hyperemia were found in the CLIP group. Surgical manipulation of the brain significantly reduced oxygen metabolism in the operated frontal lobe. PET data alone may not have independent prognostic value for detecting delayed cerebral ischemia or in predicting neurological outcome.
