ABSTRACT
BACKGROUND: Naoxueshu oral liquid is the only approved drug for acute treatment of cerebral hemorrhage in China. It has been used widely for the treatment of acute ischemic stroke and acute hemorrhagic stroke. However, safety and efficacy data on the early use of Naoxueshu oral liquid are lacking. The main purpose of this study is to observe the benefit and safety of early use of Naoxueshu oral liquid (< 72 h of cerebral hemorrhage) and offer evidence into the potential superiority of Naoxueshu oral liquid in patients with hemorrhagic stroke, and its healthcare costs. METHODS: This registration study for the prevention and treatment of cerebral hemorrhage using Naoxueshu oral liquid will be a quantitative, prospective, multicenter, observational clinical registry study. We aim to register 2000 patients with cerebral hemorrhage within 7 days of disease onset. This study will be an observational study and not interfere with the medication regimen of participants. Hence, we will not allocate patients. The main observation indicators will be the hematoma volume and the proportion of reduction 14 days post-cerebral hemorrhage (or at hospital discharge), onset of new stroke (ischemic stroke, hemorrhagic stroke) within 12 months of disease onset, independence in everyday life activities (modified Rankin Scale score ≤ 2), total cost during hospitalization, and treatment costs. CONCLUSION: This registration study will offer strong evidence for the efficacy and safety of Naoxueshu oral liquid for the prevention and treatment of cerebral hemorrhage, particularly with regard to early use (72 h after onset). It will offer evidence into the potential advantages of Naoxueshu oral liquid in patients with hemorrhagic stroke, including healthcare costs.

A 71-year-old male who suffered from Hoehn and Yahr stage III Parkinson's disease with bradykinesia, rigidity and a 5-6-Hz tremor at rest in the right extremities was admitted to our hospital due to the sudden onset of vertigo. Right cerebellar hemorrhage was confirmed by CT. The patient's resting tremor in the right extremities disappeared immediately following the cerebellar hemorrhage. Six days later, MRI showed Wallerian degeneration in the cerebello-rubro-thalamic tract. Approximately 5 months later, a 2-3-Hz Holmes' tremor gradually appeared in the right upper extremity. This tremor was improved by increasing L-dopa doses. Case reports of the disappearance of Parkinson's resting tremor and subsequent emergence of Holmes' tremor due to cerebellar lesion are rare. Furthermore, the Wallerian degeneration of the cerebello-rubro-thalamic tract identified on MRI between tremors of the different frequencies is very rare. We hypothesize that the cause of the tremor frequency change was simultaneous damage to the nigro-striatal network and the cerebello-thalamo-cerebral network.

BACKGROUND: Decreased organ function and poor physical compensatory capacity in elderly patients diagnosed with spontaneous intracerebral hemorrhage (ICH) can make surgical treatment procedures challenging and risky. Minimally invasive puncture drainage (MIPD) combined with urokinase infusion therapy is a safe and feasible method of treating ICH. This study aimed to compare the treatment efficacy of MIPD conducted under local anesthesia using either 3DSlicer + Sina application or computer tomography (CT)-guided stereotactic localization of hematomas in elderly patients diagnosed with ICH. METHODS: The study sample included 78 elderly patients (≥ 65 years of age) diagnosed with ICH for the first time. All patients exhibited stable vital signs and underwent surgical treatment. The study sample was randomly divided into two groups, either receiving 3DSlicer+Sina or CT-guided stereotactic assistance. The preoperative preparation time; hematoma localization accuracy rate; satisfactory hematoma puncture rate; hematoma clearance rate; postoperative rebleeding rate; Glasgow Coma Scale (GCS) score after 7 days; and modified Rankin scale (mRS) score 6 months after surgery were compared between the two groups. RESULTS: No significant differences in gender, age, preoperative GCS score, preoperative hematoma volume (HV), and surgical duration were observed between the two groups (all p-values > 0.05). However, the preoperative preparation time was shorter in the group receiving 3DSlicer + Sina assistance compared to that receiving CT-guided stereotactic assistance (p-value < 0.001). Both groups exhibited significant improvement in GCS scores and reduction in HV after surgery (all p-values < 0.001). The accuracy of hematoma localization and puncture was 100% in both groups. There were no significant differences in surgical duration, postoperative hematoma clearance rate, rebleeding rate, postoperative GCS and mRS scores between the two groups (all p-values > 0.05). CONCLUSIONS: A combination of 3DSlicer and Sina is effective in accurately identifying hematomas in elderly patients with ICH exhibiting stable vital signs, thus simplifying MIPD surgeries conducted under local anesthesia. This procedure may also be preferred over CT-guided stereotactic localization in clinical practice due to its ease of use and accuracy in hematoma localization.

OBJECTIVE: Hypophosphatemia often occurs after spontaneous intracerebral hemorrhage, but the effect of hypophosphatemia on its prognosis is under debate. METHODS: Clinical data of patients with spontaneous intracerebral hemorrhage admitted to our neurosurgery department from January 2018 to June 2020 were retrospectively analyzed. The patients were divided into the hypophosphatemia group and the nonhypophosphatemia group according to the serum phosphorus test values obtained three times within 1 week after admission. The incidence of complications during hospitalization, 28-day mortality, and 6-month mRS score were compared between the two groups. The influence of low phosphorus in patients with hypophosphatemia on the 6-month mRS score was explored. RESULTS: A total of 133 patients were included, of which 85 had hypophosphatemia. Forty-two patients (21 in the hypophosphatemia group and 21 in the nonhypophosphatemia group) were enrolled after propensity score matching. There were no statistically significant differences in the incidence of complications during hospitalization, 28-day mortality, and 6-month mRS score between the two groups (P > 0.05). In 85 patients with hypophosphatemia, the minimum serum phosphorus was associated with the 6-month mRS score (B = - 3.153, 95% CI: - 5.842 ~ - 0.463, P = 0.022). The cutoff value of serumphosphorus for predicting 6-month mRS score was 0.505 mmol/l. CONCLUSION: Whether hypophosphatemia occurred during hospitalization in patients with spontaneous intracerebral hemorrhage showed no effect on the incidence of complications, 28-day mortality, and 6-month mRS score. A significant decrease in serum phosphorus during hospitalization (≤ 0.505 mmol/l) might correlate with a poor 6-month mRS score. Maintaining serum phosphorus stability after spontaneous intracerebral hemorrhage may improve prognosis.

BACKGROUND: Intracerebral hemorrhage (ICH) is the deadliest form of stroke. In observational studies, lower serum magnesium has been linked to more hematoma expansion (HE) and intracranial hemorrhage, implying that supplemental magnesium sulfate is a potential acute treatment for patients with ICH and could reduce HE. FAST-MAG (Field Administration of Stroke Therapy - Magnesium) was a clinical trial of magnesium sulfate started prehospital in patients with acute stroke within 2 hours of last known well enrolled. CT was not required prior to enrollment, and several hundred patients with acute ICH were enrolled. In this ancillary analysis, we assessed the effect of magnesium sulfate treatment upon HE in patients with acute ICH. METHODS: We retrospectively analyzed data that were prospectively collected in the FAST-MAG study. Patients received intravenous magnesium sulfate or matched placebo within 2 hours of onset. We compared HE among patients allocated to intravenous magnesium sulfate or placebo with a Mann-Whitney U. We used the same method to compare neurological deficit severity (National Institutes of Health Stroke Scale) and global disability (modified Rankin Scale) at 3 months. RESULTS: Among 268 patients with ICH meeting study entry criteria, mean 65.4±13/4 years, 33% were female, and 211 (79%) had a history of hypertension. Initial deficit severities were median (interquartile range) of 4 (3-5) on the Los Angeles Motor Scale in the field and National Institutes of Health Stroke Scale score of 16 (9.5-25.5) early after hospital arrival. Follow-up brain imaging was performed a median of 17.1 (11.3-22.7) hours after first scan. The magnesium and placebo groups did not statistically differ in hematoma volume on arrival, 10.1 (5.6-28.7) versus 12.4 (5.6-28.7) mL (P=0.6), or HE, 2.0 (0.1-7.4) versus 1.5 (-0.2 to 8) mL (P=0.5). There was no difference in functional outcomes (modified Rankin Scale score of 3-6), 59% versus 50% (P=0.5). CONCLUSIONS: Magnesium sulfate did not reduce HE or improve functional outcomes at 90 days. A benefit for patients with initial hypomagnesemia was not addressed. REGISTRATION: URL: https://www.

BACKGROUND AND PURPOSE: Subpial hemorrhage is a rare form of neonatal stroke, still poorly understood. The aim of this study was to characterize a cohort of term and preterm neonates with subpial hemorrhages and contribute to a better knowledge of this condition. MATERIAL AND METHODS: Clinical records and magnetic resonance (MR) imaging data of all neonates with subpial hemorrhage followed at a pediatric hospital between 2010 and 2020 were retrospectively reviewed. RESULTS: A total of 10 patients were included in the analysis, 40% of whom were term neonates. Operative vaginal delivery was registered in 30%. Temporal was the most common location of subpial hemorrhage (70%), and all patients displayed underlying brain infarction. A characteristic yin-yang pattern was present in 90% of the study cohort, and ingurgitation of medullary veins on susceptibility weighted imaging in 80%. Cerebellar microbleeds were observed in 60% of neonates, both term and preterm. When available, MR angiography and venography were unremarkable. Patients' clinical outcome was variable, with early prematurity not associated to worse outcomes. CONCLUSION: Subpial hemorrhage has a distinctive MR pattern, with underlying parenchymal venous infarction, and can occur in term and preterm neonates. This study results suggest an association between subpial hemorrhage and cerebellar microbleeds but further studies are required to confirm it and better understand the pathophysiology of subpial hemorrhage.

BACKGROUND: The objective of this study was to evaluate factors associated with intraventricular hemorrhage (IVH) expansion and its association with long-term outcomes. METHODS: We performed a post hoc analysis of the international, multi-center CLEAR III trial (Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage) which enrolled IVH patients between September 1, 2009, and January 31, 2015. The exposure was IVH expansion, defined as >1 mL increase in volume between baseline and stability computed tomography scans, before treatment randomization. We assessed factors associated with IVH expansion and secondarily assessed the relationship of IVH expansion with clinical outcomes: composite of death or major disability (modified Rankin Scale score, >3), and mortality alone at 6 months. The relationship of IVH expansion on ventriculoperitoneal shunt placement was additionally explored. Multivariable logistic regression was used for all analyses. RESULTS: Of 500 IVH patients analyzed, the mean age was 59 (±11) years old, 44% were female and 135 (27%) had IVH expansion. In multivariable regression models, factors associated with IVH expansion were baseline parenchymal intracerebral hemorrhage (ICH) volume (adjusted odds ratio [OR], 1.04 per 1 mL increase [95% CI, 1.01-1.08]), presence of parenchymal hematoma expansion: >33% (adjusted OR, 6.63 [95% CI, 3.92-11.24]), time to stability head CT (adjusted OR, 0.71 per 1 hour increase [95% CI, 0.54-0.94]), and thalamic hematoma location (adjusted OR, 1.68 [95% CI, 1.01-2.79]) while additionally adjusting for age, sex, and race. In secondary analyses, IVH expansion was associated with higher odds of poor 6-month outcomes (adjusted OR, 1.84 [95% CI, 1.12-3.02]) but not mortality (OR, 1.40 [95% CI, 0.78-2.50]) after adjusting for baseline ICH volume, thalamic ICH location, age, anticoagulant use, Glasgow Coma Scale score, any withdrawal of care order, and treatment randomization arm. However, there were no relationships of IVH expansion on subsequent ventriculoperitoneal shunt placement (adjusted OR, 1.02 [95% CI, 0.58-1.80]) after adjusting for similar covariates. CONCLUSIONS: In a clinical trial cohort of patients with large IVH, acute hematoma characteristics, specifically larger parenchymal volume, hematoma expansion, and thalamic ICH location were associated with IVH expansion. Given that IVH expansion resulted in poor functional outcomes, exploration of treatment approaches to optimize hemostasis and prevent IVH expansion, particularly in patients with thalamic ICH, require further study.

OBJECTIVE: To evaluate the efficacy and safety outcome and related risk factors of Naoxueshu in the treatment of acute SICH. METHODS: Two hundred twenty patients were enrolled in this study. Diagnosis of SICH was based on neuroimaging. All the patients received regular treatment and Naoxueshu oral liquid 10 ml 3 times a day for 14 consecutive days. Surgical intervention was conducted as needed. Efficacy and safety outcomes were evaluated. RESULTS: Hematoma volume decreased significantly 7 days after Naoxueshu treatment (from 27.3 ± 20.0 to 15.1 ± 15.1 ml, P < 0.0001), and it decreased further in 14-day result (6.9 ± 10.4 ml, P < 0.0001). Patients' neurological function was improved remarkably with NIHSS scores from baseline 13 points to 7-day 7 points (P < 0.0001) and 14-day 4 points (P < 0.0001). Cerebral edema was relieved only 14 days after Naoxueshu treatment (from 3 to 2 points, P < 0.0001). No clinically significant change was found in 7-day and 14-day safety results. Female sex was related independently to large 7-day hematoma volume and worse 7-day NIHSS score while it would not affect patients' 14-day outcomes. Rare cause of SICH (B = 17.4, P = 0.009) alone was related to large 14-day hematoma volume. Worse baseline NIHSS score (B = 0.3, P = 0.003) and early use of Naoxueshu (B = 2.9, P = 0.005) were related to worse 7-day and14-day neurological function. CONCLUSION: Naoxueshu oral liquid could relieve hematoma volume and cerebral edema safely; meanwhile, it could improve patients' neurological function. Sex, cause of SICH, and time from onset to receive Naoxueshu should be taken into consideration in the treatment of SICH.

OBJECTIVE: To evaluate the protective efficacy of Sanqi (Radix Notoginseng) on cerebral hemorrhage in a rat model of traumatic brain injury (TBI) by investigating plasminogen activator inhibitor-1 (PAI-1), tissue-type plasminogen activator (t-PA), nuclear factor-κB (NF-κB, p-p65), nitric oxide (NO), endothelin (ET), cluster differentiation (CD61CD62), and coagulation. METHODS: The free-fall method was used to create a rat model of TBI. Forty-eight rats were randomly divided into six groups: the blank group, sham group, model group, low-dose Sanqi (Radix Notoginseng) group, middle-dose Sanqi (Radix Notoginseng) group, and high-dose Sanqi (Radix Notoginseng) group. At 24 h after the model was created, we investigated brain MRI, brain tissue morphology using HE staining, flow cytometry, and immunohistochemical changes. RESULTS: Cerebral hemorrhage was aggravated in TBI rats (observed in brain specimens, brain MRI, and brain tissue HE). Cerebral immunohistochemistry results demonstrated that the expression of t-PA, PAI-1 and p-p65 increased significantly in TBI rats, while t-PA/PAI-1 had a significant decrease. In addition, CD61CD62, D2D, and ET were significantly increased in TBI rats, and PT and APTT were significantly prolonged; in contrast, NO was significantly decreased. Sanqi (Radix Notoginseng) decreased cerebral hemorrhage in TBI rats (observed in brain MRI and brain tissue HE), and increased t-PA/PAI-1, CD61CD62 significantly. It also significantly decreased the expression of t-PA, PAI-1, and p-p65 in brain immunohistochemistry and significantly decreased PT, APTT, D2D, and ET. However, there were no differences in NO between the model group and the Sanqi (Radix Notoginseng) group. CONCLUSION: Sanqi (Radix Notoginseng) can decrease the expression of p-p65, increase t-PA/PAI-1, and stem traumatic intracranial hemorrhage in a TBI rat model.

RATIONALE: Neurogenic fever is a non-infectious source of fever in a patient with brain injury, especially hypothalamic injury. We report on a stroke patient with neurogenic fever due to injury of hypothalamus, demonstrated by using diffusion tensor imaging (DTI). PATIENT CONCERNS: A 28-year-old male patient was admitted to the rehabilitation department of university hospital at 30 months after onset. Brain MRI showed leukomalactic lesions in hypothalamus, bilateral medial temporal lobe, and bilateral basal ganglia. He showed intermittent high body temperature (maximum:39.5°C, range:38.5-39.2°C), but did not show any infection signs upon physical examination or after assessing his white blood cell count and inflammatory enzyme levels such as erythrocyte sedimentation rate and C-reactive protein. In addition, 8 age-matched normal (control) subjects (4 male, mean age: 26.6 years, range: 21-29years) were enrolled in the study. DIAGNOSIS: Intraventricular hemorrhage and intracerebral hemorrhage in the left basal ganglia. INTERVENTIONS: He underwent extraventricular drainage and ventriculoperitoneal shunting for hydrocephalus. OUTCOMES: DTI was performed at 30 months after onset, fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were obtained for hypothalamus. The FA and ADC values of patient were lower and higher, respectively, by more than two standard deviations from control values. Injury of hypothalamus was demonstrated in a stroke patient with neurogenic fever. LESSIONS: Our results suggest that evaluation of hypothalamus using DTI would be helpful in patients show unexplained fever following brain injury.

A 54-year-old man suddenly developed impaired consciousness and left hemiplegia due to a right thalamic hematoma. Emergent ventricular drainage for acute hydrocephalus improved the level of consciousness, but macrosquare-wave jerks (MSWJ) consisting of a right-ward intrusive saccade and corrective saccade appeared. The MSWJ disappeared on day 2 when follow-up CT revealed improvement of hydrocephalus. However, on day 36, after ventricular drainage was clamped, the MSWJ reappeared. After ventriculoperitoneal shunt, MSWJ again subsided. In this patient, hydrocephalus may have stretched the superior colliculus, thereby decreasing activity of the fixation neurons and then omnipause neurons, and eventually resulting in the reversible MSWJ.

The aim of this study is to investigate the relationship between aging and brain vasculature health. Three groups of mice, 3, 17-18, and 24 months, comparable to young adult, middle age, and old human were studied. Prussian blue histology and fast imaging with steady precession T2∗-weighted magnetic resonance imaging were used to quantify structural changes in the brain across age groups. The novel object recognition test was used to assess behavioral changes associated with anatomical changes. This study is the first to show that the thalamus is the most vulnerable brain region in the mouse model for aging-induced vascular damage. Magnetic resonance imaging data document the timeline of accumulation of thalamic damage. Histological data reveal that the majority of vascular damage accumulates in the ventroposterior nucleus and mediodorsal thalamic nucleus. Functional studies indicate that aging-induced vascular damage in the thalamus is associated with memory and sensorimotor deficits. This study points to the possibility that aging-associated vascular disease is a factor in irreversible brain damage as early as middle age.

The Cheiro-Oral (COS) Syndrome is a rare neurologic condition characterized by sensory disturbances involving the peri-oral area and the upper extremity, typically isolated to the hand or fingers. The thalamus contralateral to the symptomatic side is the brain region most commonly involved. Most cases are caused by ischemic or hemorrhagic strokes, although other structural lesions have been implicated. These include tumors, subdural hematomas, aneurysms, and infections. The unusual and seemingly unrelated nature of the symptoms may contribute to misdiagnosis and incomplete workup for potentially serious conditions. We are unable to identify a report of this condition in the emergency medicine literature despite the emergency department being the likely point of presentation for patients with COS. In this report, we describe two patients with COS who presented to our emergency department and review the features of COS as described in published case reports.

OBJECTIVES: Surgical treatment is expected to remove clot immediately in acute spontaneous intracerebral hemorrhage (SICH) patients. The aim of this study was to evaluate whether Naoxueshu could enhance the efficacy of clot removal surgery in acute SICH patients. METHODS: One hundred twenty patients who had been diagnosed as SICH according to neuroimaging were enrolled in this study. They received craniotomy, decompressive craniectomy, or minimally invasive surgical evacuation as appropriate and then were randomized into two groups: the Naoxueshu group (NXS group, n = 60) and the control group (n = 60). All the patients received standard medical management while patients in NXS group also took Naoxueshu oral liquid 10 ml with three times a day for seven consecutive days. The primary outcome was the 7-day hematoma volume and secondary outcomes were 7-day National Institutes of Health Stroke Scale (NIHSS) score and 7-day cerebral edema score. RESULTS: After clot removal surgery, hematoma volume in NXS group (9.5 ± 8.0) was significantly decreased than that in Control group (21.3 ± 22.9, p < .0001) 7 days after surgery. Moreover, cerebral edema was also relieved after 7-day's Naoxueshu treatment (2.5 ± 0.9 vs. 2.9 ± 0.7, p = .043). Since patients in NXS group had worse baseline NIHSS score (17.2 ± 8.1 vs. 13.7 ± 10.1, p = .039), it was reasonable to conclude that Naoxueshu treatment could improve patients' neurological function because 7-day NIHSS score of the two groups was similar. CONCLUSION: Naoxueshu oral liquid could relieve hematoma volume and cerebral edema after clot removal surgery in acute SICH patients. Moreover, it had the potential to improve patients' short-term neurological function.

BACKGROUND AND PURPOSE: Neonatal subpial hemorrhage with underlying cerebral infarct is a previously described but poorly understood clinicoradiographic syndrome. We sought to further characterize the cranial ultrasound and MR imaging characteristics and associated outcomes of this condition across the full range of gestational ages, including extreme and very preterm neonates. MATERIALS AND METHODS: This was a single tertiary pediatric center retrospective case series. Brain MR imaging and cranial ultrasound of neonates with subpial hemorrhage with underlying cerebral infarct were identified from a population-based radiology registry (2006-2020). Original images were reviewed by 2 neuroradiologists blinded to history and outcome. Clinical presentation, course, and outcome at >12 months were abstracted from medical records. The diagnostic utility of cranial ultrasound was compared with that of MR imaging. RESULTS: Sixteen patients were included (median gestational age, 36.5 weeks; range, 27-41 weeks; 31% premature). MR images were obtained acutely at the time of presentation between days 0 and 9 of life. On T2WI and DWI, a consistent presence of a hypointense subpial bleed and an underlying hyperintense cerebral cortex were recognized, which created a distinct MR imaging pattern resembling the yin-yang symbol. Findings of all the MRAs and MRVs were normal. Cranial ultrasound detected 6 of 7 MR imaging lesions with sonographic features correlating well with MR imaging. The 3 extreme or very preterm neonates did not survive. The remainder survived with relatively mild neurologic deficits. CONCLUSIONS: Subpial hemorrhage with underlying infarction is a recognizable condition with unique MR imaging and sonographic features. Improved recognition may advance understanding of risk factors and outcomes.

Diffuse white matter (WM) disease is highly prevalent in elderly with cerebral small vessel disease (cSVD). In humans, cSVD such as cerebral amyloid angiopathy (CAA) often coexists with Alzheimer's disease imposing a significant impediment for characterizing their distinct effects on WM. Here we studied the burden of age-related CAA pathology on WM disease in a novel transgenic rat model of CAA type 1 (rTg-DI). A cohort of rTg-DI and wild-type rats was scanned longitudinally using MRI for characterization of morphometry, cerebral microbleeds (CMB) and WM integrity. In rTg-DI rats, a distinct pattern of WM loss was observed at 9 M and 11 M. MRI also revealed manifestation of small CMB in thalamus at 6 M, which preceded WM loss and progressively enlarged until the moribund disease stage. Histology revealed myelin loss in the corpus callosum and thalamic CMB in all rTg-DI rats, the latter of which manifested in close proximity to occluded and calcified microvessels. The quantitation of CAA load in rTg-DI rats revealed that the most extensive microvascular Aß deposition occurred in the thalamus. For the first time using in vivo MRI, we show that CAA type 1 pathology alone is associated with a distinct pattern of WM loss.

OBJECTIVES: Up to 41% of intracerebral hemorrhages (ICH) are considered cryptogenic despite a thorough investigation to determine etiology. Certain over-the-counter supplements may increase proclivity to bleeding, and we hypothesize that specifically vitamin E may have an association with ICH and acutely elevated serum levels of α-tocopherol. Our aim is to report 3 cases of recently admitted patients with hypervitaminosis E and otherwise cryptogenic ICH. METHODS: At our institution between January and December 2018, 179 patients were admitted with ICH with 73 imputed to be "cryptogenic" (without clear etiology as per Structural vascular lesions, Medication, Amyloid angiopathy, Systemic disease, Hypertension, or Undetermined and Hypertension, Amyloid angiopathy, Tumor, Oral anticoagulants, vascular Malformation, Infrequent causes, and Cryptogenic criteria). Of these, we found 3 (4.1%) clearly admitted to consistent use of vitamin E supplementation for which α-tocopherol levels were checked. We describe the clinical presentation and course of these patients and their etiologic and diagnostic evaluations including neuroimaging and α-tocopherol laboratory data. RESULTS: All patients in this series were consistently consuming higher than recommended doses of vitamin E and developed acute ICH. The first 2 patients both had subcortical (thalamic) intraparenchymal hemorrhages while the third had an intraventricular hemorrhage. Serum α-tocopherol levels in patient A, B, and C were elevated at 30.8, 46.7, and 23.3 mg/L, respectively (normal range 5.7-19.9 mg/L) with a mean of 33.6 mg/L. No clear alternate etiologies to their ICH could be conclusively determined despite thorough workups. CONCLUSIONS: In patients with cryptogenic ICH, clinicians should consider hypervitaminosis E and check serum α-tocopherol level during admission. Reviewing the patient's pharmacologic history, including over-the-counter supplements such as vitamin E, may help identify its association, and its avoidance in the future may mitigate risk. With its known vitamin K antagonism, hypo-prothrombinemic effect, cytochrome p-450 interaction, and antiplatelet activity, vitamin E may not be as benign as presumed. Its consumption in nonrecommended doses may increase ICH risk, which may be underestimated and under-reported.
