Virtual brain twins are personalized, generative and adaptive brain models based on data from an individual's brain for scientific and clinical use. After a description of the key elements of virtual brain twins,we present the standard model for personalized whole-brain network models. The personalization is accomplished using a subject's brain imaging data by three means:(1) assemble cortical and subcortical areas in the subject-specific brain space;(2) directly map connectivity into the brain models, which can be generalized to other parameters; and(3) estimate relevant parameters through model inversion, typically using probabilistic machine learning. We present the use of personalized whole-brain network models in healthy ageing and five clinical diseases: epilepsy, Alzheimer's disease, multiple sclerosis, Parkinson's disease and psychiatric disorders. Specifically, we introduce spatial masks for relevant parameters and demonstrate their use based on the physiological and pathophysiological hypotheses. Finally, we pinpoint the key challenges and future directions.

Background Atrial cardiomyopathy(AC)is an emerging concept explaining the pathophysiology of cardioembolic strokes in absence of atrial fibrillation(AF).A definition based on the presence of electrical abnormality(P-wave terminal force in lead V1(PTFV1)>5000µV×ms),N-Terminal pro-B-type natriuretic peptide(NT pro BNP)>250pg/mL and/or indexed left atrial diameter(LADI)>3cm/m^(2)is currently tested in the ARCADIA(AtRial Cardiopathy and Antithrombotic Drugs In prevention After cryptogenic stroke)*** set out to estimate the prevalence of AC as defined in the ARCADIA trial,its determinants and its association with AF detected after stroke(AFDAS).Methods Stepwise screening for silent Atrial Fibrillation After Stroke(SAFAS)study prospectively included 240 ischaemic stroke *** markers were complete for 192 of them and 9 were not included in this analysis because AF had been diagnosed on *** A total of 183 patients were analysed,of whom 57%(104 patients)met the AC criteria(79 NT-proBNP,47 PTFV1,4 LADI).In the multivariate logistic regression,C reactive protein>3mg/L(OR(95%CI)2.60(1.30 to 5.21),p=0.007)and age(OR(95%CI)1.07(1.04 to 1.10),p34mL/m^(2),OR 2.35(CI 1.09 to 5.06)p=0029).Conclusion AC as defined in ARCADIA is mostly based on NT pro BNP elevation(76%of patients)and is associated with age and ***,AC was not independently associated with AFDAS at *** ARCADIA trial,which compares aspirin to apixaban in patients with embolic strokes of undetermined source with AC markers and must,therefore be analysed in the light of these limitations.
