Collectivism Is Associated With Greater Neurocognitive Fluency in Older Adults
This study aimed to evaluate the impact of self-construal on neurocognitive functions in older adults. A total of 86 community-dwelling older adults 60 years and older were assessed with three common self-report measures of self-construal along individualism and collectivism (IC). A cognitive battery was administered to assess verbal and non-verbal fluency abilities. Latent profile analysis (LPA) was used to categorize individuals according to IC, and one-way analyses of covariance (ANCOVA), including relevant covariates (e.g., ethnicity, gender, linguistic abilities), were used to compare neurocognitive functions between ...

Consecutive Slides on Axial View Is More Effective Than Transversal Diameter to Differentiate Mechanisms of Single Subcortical Infarctions in the Lenticulostriate Artery Territory
Conclusion: Consecutive slides on axial view (≥4 consecutive slices) might be more effective than transversal diameter to identify the atherosclerotic mechanisms of SSIs in the lenticulostriate artery territory. Clinical Trial Registration: http://www.clinicaltrials.gov. Unique identifier: NCT00664846 Introduction Single subcortical infarctions (SSIs) have been considered to be caused by lipohyalinosis degeneration in small artery disease, traditionally called lacunar infarct (1). However, atherosclerosis occurring in the parental artery blocking the orifice of the branch artery or atherosclerosis in the p...

Age-Specific Associations of Renal Impairment and Cerebral Small Vessel Disease Burden in Chinese with Ischaemic Stroke
Recent studies in Caucasians with transient ischaemic attack or ischaemic stroke have demonstrated significant age-specific associations between cerebral small vessel disease (SVD) burden on magnetic resonance imaging and renal impairment. We aimed to validate these findings in a large cohort of Chinese with ischaemic stroke.

Late-onset mitochondrial disease in a patient with MELAS and mitochondrial DNA T14487C mutation.
We report a case of a 58-year-old male who presented with stroke-like episodes and late-onset mitochondrial encephalopathy. Brain magnetic resonance imaging (MRI) revealed multiple lesions in different locations, including in the left hypothalamus, bilateral parietal lobe, left occipital lobe, centrum semiovale and right cerebellar hemisphere. Muscle histopathological analysis showed no myopathic changes. We identified a T14487C mutation in the mitochondrial DNA (mtDNA), which causes a M63V substitution in the mitochondrial NADH dehydrogenase 6 (ND6) of complex I of the mitochondrial respiratory chain. The mutation was het...

New-Onset Geriatric Epilepsy in China: A Single-Center Study.
Conclusions: Autoimmune encephalitis is becoming an increasing risk factor of subsequent epilepsy in older people. Older patients with new epilepsy are more likely to respond to antiepileptic drugs, and drug-resistant epilepsy is uncommon. PMID: 30539903 [PubMed - in process]

Increased Neutrophil-to-lymphocyte Ratios are Associated with Greater Risk of Hemorrhagic Transformation in Patients with Acute Ischemic Stroke.
CONCLUSIONS: Higher level of NLR is associated with greater risk of hemorrhagic transformation in patients with acute ischemic stroke, especially in cardio-embolic stroke. Moreover, the results suggest that therapeutic interventions that may increase the risk of bleeding should be undertaken carefully in the management of AIS patients with higher NLR.

Association Between PPARs Gene Functional Polymorphisms and Ischemic Stroke in Chinese Uyghur Population
AbstractPPAR γ and PPARα belong to a receptor family of ligand-activated transcription factors involved in the regulation of inflammation, cellular glucose uptake, protection against atherosclerosis and endothelial cell function. Through these effects, they might be involved with the ischemic stroke (IS). We r ecruited 100 IS patients diagnosed by CTs or/and magnetic resonance imaging (MRI) and 100 normal healthy controls from Chinese Uyghur Population to assess the nature of the functional polymorphisms of PPARs and any links with IS in this unique population which has 60% European ancestry and 40% East Asian ancestry. ...

Recurrent cerebellar infarction associated with hereditary heterozygous protein C deficiency in a 35-year-old woman: A case report and genetic study on the pedigree.
In conclusion, the clinical manifestations of hereditary PROC deficiency may vary between individuals. The heterozygous mutation locus c.565C>T on the PROC gene is associated with thrombophilia. Awareness of the association between natural anticoagulants and thrombophilia may promote the prevention and therapy of stroke. PMID: 30210609 [PubMed]

Bu Yang Huan Wu Decoction prevents reperfusion injury following ischemic stroke in rats via inhibition of HIF-1 α, VEGF and promotion β-ENaC expression
ConclusionsBYHW protected against cerebral I/R injury in MCAO rats through inhibiting the activation of the HIF-1 α /VEGF pathway and stabilizing ion channel of β-ENaC in brain, indicating that BYHW shows potential for stroke treatment in acute stage.Graphical abstract

A Chinese CARASIL Patient Caused by Novel Compound Heterozygous Mutations in HTRA1
Our objective is to reported a Chinese CARASIL patient caused by novel compound heterozygous mutations in HTRA1. Detailed clinical and neuroimaging examination were conducted in proband and her available family members. Sanger sequencing of NOTCH3 and HTRA1 was used to investigate causative mutations. The patient was born in an outbred family. She experienced recurrent transient ischemic attacks, hair loss, and low back pain. Brain magnetic resonance imaging showed multiple lacunar infarctions, diffuse leukoencephalopathy, and multiple microbleeds of white matter.

Antiplatelet Treatment After Transient Ischemic Attack and Ischemic Stroke in Patients With Cerebral Microbleeds in 2 Large Cohorts and an Updated Systematic Review Clinical Sciences
Background and Purpose—In patients with transient ischemic attack/ischemic stroke, microbleed burden predicts intracerebral hemorrhage (ICH), and ischemic stroke, but implications for antiplatelet treatment are uncertain. Previous cohort studies have had insufficient follow-up to assess the time course of risks, have not stratified risks by antithrombotic use, and have not reported extracranial bleeds or functional outcome of ICH versus ischemic stroke.Methods—In 2 independent prospective cohorts with transient ischemic attack/ischemic stroke (Oxford Vascular Study/mainly white; University of Hong Kong/mainly Chinese),...

Crossed aphasia following cerebral infarction in a right-handed patient with atypical cerebral language dominance
ConclusionThe findings suggest that the patient has right-sided cerebral language dominance, or that both hemispheres have linguistic functions. Not all patients show linguistic capabilities on the side opposite hand preference. The language dominance should be predicted by a combination of clinical manifestations and functional imaging techniques.
