Value of Eye Movement Exam in Aiding Precise Localization in Stroke (P1.016)
We present an unusual presentation of midbrain stroke presenting with bilateral ptosis in an African American male with vascular risk factors and concurrent use of bevacizumab. This case illustrates how detailed knowledge of anatomy and detailed neurologic exam remain valuable tools for localizing and diagnosing subtle presentations of common neurologic disease. Case description: A 69 year-old African American man with vascular risk factors including hypertension, hyperlipidemia and poorly controlled diabetes experienced sudden onset horizontal diplopia associated with fatigue. The patient presented to the Emergency Depart...

Underlying embolic and pathologic differentiation by cerebral microbleeds in cryptogenic stroke
ConclusionsCMBs were common, and age, male sex, hypertension, chronic kidney disease, and cerebral white matter diseases were related to CMBs in cryptogenic stroke. Aortic complicated lesions were associated with deep and diffuse CMBs, while prior anticoagulant therapy was related to lobar CMBs.

Trimethylamine N-Oxide and White Matter Hyperintensity Volume Among Patients With Acute Ischemic Stroke
CONCLUSIONS AND RELEVANCE: In this observational study, TMAO was associated with cerebral small vessel disease determined by WMHV and acute lacunar infarction. The association was independent of traditional vascular risk factors.PMID:37610752 | DOI:10.1001/jamanetworkopen.2023.30446

Blood Pressure After Recent Stroke: Baseline Findings From the Secondary Prevention of Small Subcortical Strokes Trial.
CONCLUSIONS: In this cohort with symptomatic lacunar stroke, more than half had uncontrolled hypertension at approximately 2.5 months after stroke. Regional, racial, and clinical differences should be considered to improve control and prevent recurrent stroke. CLINICAL TRIALS REGISTRATION: Trial Number NCT00059306.

What is the diagnostic value of head MRI after negative head CT in ED patients presenting with symptoms atypical of stroke?
The objective of this study is to detect the subgroup of patients with such presentations having minor strokes whom may benefit from primary and secondary stroke prevention. We conducted a retrospective analysis and stratified patient risk factors associated with positive findings on subsequent head MRI ordered by the emergency department physician following a normal head CT. Two hundred fifty-two patients presenting with atypical stroke symptoms to the emergency department had a negative head CT followed by head MRI within 24 h ordered by emergency department clinician (123 males and 129 females; mean age of 59.4). Twent...

Microbleeds in the Secondary Prevention of Small Subcortical Strokes Trial: Stroke, Mortality, and Treatment Interactions
ObjectiveTo characterize cerebral microbleeds (CMBs) in lacunar stroke patients in the Secondary Prevention of Small Subcortical Strokes (SPS3) trial and to assess their relationship with recurrent stroke and death, and response to assigned treatment. MethodsSPS3 is a randomized, clinical trial conducted between 2003 and 2011. Patients with recent magnetic resonance imaging (MRI)‐documented lacunar infarcts were randomly assigned in a factorial design to target levels of systolic blood pressure (130–149mmHg vs <130mmHg; open label) and to antiplatelet treatment (aspirin/clopidogrel vs aspirin/placebo; double‐blind...

Cardiac papillary fibroelastoma and stroke during pregnancy: Case report.
We report the case of a woman with severe headache associated with visual disturbances, without hypertension or proteinuria at 32 weeks of pregnancy. MRI revealed multiple recent cerebral vascular accidents. An echocardiogram detected a papillary fibroelastoma of 5mm. Maternal fetal experts determined it safe to continue the pregnancy. Childbirth at 39 weeks was normal uneventful for the newborn and mother. In the postpartum, despite the theoretical operative indication to resect the small residual papillary fibroelastoma, the patient was followed expectantly because of the stable neuro-cardiologic state. A fibroelastoma c...

Sex Differences in Intracranial Atherosclerosis in Patients With Hypertension With Acute Ischemic Stroke
Conclusions Men with hypertension with acute ischemic stroke have significantly higher total and proximal plaque burdens than women. Women with hypertension on anti-hypertensive medication showed a greater reduction in proximal plaque burden than men. Further confirmation with a longitudinal cohort study is needed and may help evaluate whether different treatment guidelines for managing hypertension by sex can help reduce intracranial atherosclerosis burden and ultimately acute ischemic stroke risk.PMID:35574965 | DOI:10.1161/JAHA.122.025579

Early Clinical Signs, Lesion Localization, and Prognostic Factors in Unilateral Symptomatic Internal Carotid Artery Occlusion
Conclusions: In unilateral symptomatic intracranial carotid artery occlusion, poor prognosis and high mortality–associated territorial stroke pattern is frequently observed. Besides, presence of severe stenosis or occlusion and absence of collateral circulation in MCA are associated with poor prognosis.

Grading and Interpretation of White Matter Hyperintensities Using Statistical Maps Clinical Sciences
Conclusions— We have generated a novel graphical WMH grading (Kim statistical WMH scoring) system, correlated to risk factors and adjusted for age/hypertension. Further studies are required to confirm whether the combined data set allows grading of WMH burden in individual patients and a tailored patient-specific interpretation in ischemic stroke-related clinical practice.

Left ventricular geometry and white matter lesions in ischemic stroke patients.
Authors: Butenaerts D, Chrzanowska-Wasko J, Slowik A, Dziedzic T Abstract Abnormal left ventricular (LV) geometry is associated with extracardiac organ damage in patients with hypertension. The aim of this study was to determine the relationship between LV geometry and white matter lesions (WMLs) in ischemic stroke patients. We retrospectively analyzed data from 155 patients (median age 62; 49.8% male) with mild ischemic stroke (median National Institutes of Health Stroke Scale score 4) who underwent brain magnetic resonance imaging and echocardiography. Patients were categorized into four groups: normal LV geometr...
