The prevalence and prognosis of asymptomatic intracranial atherosclerosis in a community-based population: Results based on high-resolution magnetic resonance imaging
CONCLUSIONS: We found that ICAD detected using HR-MRI increases the long-term risk of a first-ever ischemic stroke in a stroke-free population, suggesting that the current primary prevention protocol of stroke awaits further optimization.PMID:37738517 | DOI:10.1111/ene.16057

Case report: Heterozygous mutation in HTRA1 causing typical cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy
Conclusion: This case suggests that patients carrying a heterozygous mutation in G905A may also have typical clinical features of CARASIL, which allows us to have a more comprehensive understanding of CARASIL.

Incidence, characteristics and outcome of post-stroke recrudescence in the Chinese population: a single-centre observational study
Conclusions PSR is not uncommon in patients presenting with stroke symptoms and can be distinguished from TIA and SMs based on a combination of clinical features and trigger in the Chinese population. The neurological deficits of patients with PSR often resolve within several days following the resolution of the trigger.

Improved cerebral blood flow and hippocampal blood flow in stroke ‐free patients after catheter ablation of atrial fibrillation
ConclusionSR restoration with catheter ablation was associated with improved CBF and HBF at 3 months, maintenance of blood flow, and improved cognitive function at 12 months.

Statins may Decrease Aneurysm wall Enhancement of Unruptured Fusiform Intracranial Aneurysms: A high-resolution 3T MRI Study
AbstractInflammation plays an integral role in the formation, growth, and progression to rupture of unruptured intracranial aneurysms. Aneurysm wall enhancement (AWE) in high-resolution magnetic resonance imaging (HR-MRI) has emerged as a surrogate biomarker of vessel wall inflammation and unruptured intracranial aneurysm instability. We investigated the correlation between anti-inflammatory drug use and three-dimensional AWE of fusiform intracranial aneurysms (FIAs). We retrospectively analyzed consecutive patients with FIAs in our database who underwent 3T HR-MRI at three Chinese centers. FIAs were classified as fusiform...

Iatrogenic Air Embolisms During Endovascular Interventions: Impact of Origin and Number of Air Bubbles on Cerebral Infarctions
ConclusionIatrogenic AEs originating at the ascending aorta cause a  similar number and pattern of cerebral infarctions compared to those with origin at the carotid artery. These findings underline the relevance and potential risk of AE occurring during endovascular interventions at the aortic valve and ascending aorta.

A right convergence area of the prefrontal lobe is involved in the improvement of semantic fluency in patients with post-stroke aphasia
CONCLUSION: The improvement of semantic fluency in subacute PSA patients may require the participation of the right convergence area of the prefrontal lobe.PMID:37651207 | DOI:10.1080/10749357.2023.2253632

Cerebral Microbleed Patterns and Cortical Amyloid- β: The ARIC-PET Study
CONCLUSIONS: In this community-based cohort of nondemented adults, lobar-only pattern of CMBs or superficial siderosis is most strongly associated with brain Aβ, with no elevated risk for a mixed CMB pattern. Further studies are needed to understand differences in CMB patterns and their meaning across subgroups.PMID:37638398 | DOI:10.1161/STROKEAHA.123.042835

Diffusion tensor imaging magnetic resonance imaging (DTI-MRI) helps to tailor speech therapy: A case report with a short narrative review
CONCLUSION: Brain MRI is confirmed as a multimodal tool evaluating the damage, both from the point of structural and functional view. Tractography in aphasia allows focusing on major pathways. The involvement of the arcuate fascicle, whose lesion disconnects Broca's and Wernicke's areas, is related to clinical improvement, and represents a neural correlate of the brain injury recovery process that physicians and speech therapists might be aware of it, tailoring the plane of care of each patient.PMID:37638456 | DOI:10.3233/NRE-230082
