Retinal imaging, used for assessing stroke-related retinal changes, is a non-invasive and cost-effective method that can be enhanced by machine learning deep algorithms, showing promise in early disease detection, severity grading, prognostic evaluation stroke patients. This review explores the role of artificial intelligence (AI) patient care, focusing on imaging integration into clinical workflows. has revealed several microvascular including decrease central artery diameter an increase vein diameter, both which are associated with lacunar intracranial hemorrhage. Additionally, such as arteriovenous nicking, increased vessel tortuosity, arteriolar light reflex, decreased fractals, thinning nerve fiber layer also reported to higher risk. AI models, Xception EfficientNet, have demonstrated accuracy comparable traditional risk scoring systems predicting For diagnosis, models like Inception, ResNet, VGG, alongside classifiers, shown high efficacy distinguishing patients from healthy individuals using imaging. Moreover, random forest model effectively distinguished between ischemic hemorrhagic subtypes based features, superior predictive performance compared characteristics. support vector achieved classification pial collateral status. Despite this advancements, challenges lack standardized protocols modalities, hesitance trusting AI-generated predictions, insufficient data electronic health records, need validation across diverse populations, ethical regulatory concerns persist. Future efforts must focus validating ensuring algorithm transparency, addressing issues enable broader implementation. Overcoming these barriers will essential translating technology personalized care improving outcomes.

Background Intracranial haemorrhage (ICH) poses a significant threat to patients on Direct Oral Anticoagulants (DOACs), with existing risk scores inadequately predicting ICH in these patients. We aim develop and validate predictive model for DOAC-treated Methods 24,794 treated DOAC were identified province-wide electronic medical health data platform Tianjin, China. The cohort was randomly split into 4:1 ratio development validation. utilized forward stepwise selection, Least Absolute Shrinkage Selection Operator (LASSO), eXtreme Gradient Boosting (XGBoost) select predictors. Model performance compared using the area under curve (AUC) net reclassification index (NRI). optimal stratified model. Results median age is 68.0 years, 50.4% of participants are male. XGBoost model, incorporating six independent factors (history hemorrhagic stroke, peripheral artery disease, venous thromboembolism, hypertension, age, low-density lipoprotein cholesterol levels), demonstrated superior dateset. It showed moderate discrimination (AUC: 0.68, 95% CI: 0.64–0.73), outperforming (ΔAUC = 0.063, P 0.003; NRI 0.374, < 0.001). Risk categories significantly (low risk: 0.26%, 0.74%, high 5.51%). Finally, consistent internal Conclusion In real-world Chinese population therapy, this study presents reliable risk. integrating key factors, offers valuable tool individualized assessment context oral anticoagulation therapy.

Abstract Background Machine learning (ML) risk prediction models for post-stroke cognitive impairment (PSCI) are still far from optimal. This study aims to generate a reliable predictive model predicting PSCI in Chinese individuals using ML algorithms. Methods We collected data on 494 who were diagnosed with acute ischemic stroke (AIS) and hospitalized this condition January 2022 November 2023 at medical institution. All of the observed samples divided into training set (70%) validation (30%) random. Logistic regression combined least absolute shrinkage selection operator (LASSO) was utilized efficiently screen optimal features PSCI. seven different (LR, XGBoost, LightGBM, AdaBoost, GNB, MLP, SVM) compared their performance resulting variables. used five-fold cross-validation measure model's area under curve (AUC), sensitivity, specificity, accuracy, F1 score PR values. SHAP analysis provides comprehensive detailed explanation our optimized performance. Results identified 58.50% eligible AIS patients. The most HAMD-24, FBG, age, PSQI, paraventricular lesion. XGBoost model, among 7 developed based best features, demonstrates superior performance, as indicated by its AUC (0.961), sensitivity (0.931), specificity (0.889), accuracy (0.911), (0.926), AP value (0.967). Conclusion lesion is exceptional It provide clinicians tool early screening patients effective treatment decisions

Post-stroke dementia (PSD), a common complication, diminishes rehabilitation efficacy and affects disease prognosis in stroke patients. Many factors may be related to PSD, including demographic, comorbidities, examination characteristics. However, most existing methods are qualitative evaluations of independent factors, which ignore the interaction amongst various factors. Therefore, purpose this study is explore applicability machine learning (ML) for predicting PSD.

Abstract Cognitive impairments, which can be caused by neurodegenerative and cerebrovascular disease, represent a growing global health crisis with far‐reaching implications for individuals, families, healthcare systems, economies worldwide. Notably, neurodegenerative‐induced cognitive impairment often presents different pattern severity compared to cerebrovascular‐induced impairment. With the development of computational technology, machine learning techniques have developed rapidly, offers powerful tool in radiomic analysis, allowing more comprehensive model that handle high‐dimensional, multivariate data traditional approach. Such models allow prediction disease development, as well accurately classify from overlapping symptoms, therefore facilitating clinical decision making. This review will focus on application learning‐based radiomics neurogenerative disease. Within category, this primarily focuses Alzheimer's while also covering other conditions such Parkinson's Lewy body dementia, Huntington's In we concentrate poststroke impairment, including ischemic hemorrhagic stroke, additional attention given small vessel moyamoya We specific challenges limitations when applying radiomics, provide our suggestion overcome those towards end, discuss what could done future use.
