The ADC(av) values did not significantly change with aging, except for an increase in the lateral ventricles, and can be used for reference in future studies and in clinical settings.
Cerebral hemodynamics in a healthy population measured by dynamic susceptibility contrast MR imaging
The perfusion parameters did not change with age, except for a tendency to an increase in gray matter MTT and CBV, and age itself seems to have only a marginal effect on cerebral perfusion in healthy population.
Prognosis and Safety of Anticoagulation in Intracranial Artery Dissections in Adults
IADs appear to polarize into 2 groups: (1) nonaneurysmatic IADs presenting without SAH that are associated with favorable outcomes and safe anticoagulant therapy; and (2) aneurysmatic IIADs, characterized by SAH and poorer prognosis.
Leukoaraiosis Burden Significantly Modulates the Association Between Infarct Volume and National Institutes of Health Stroke Scale in Ischemic Stroke
Lukoaraiosis significantly modulates the association between infarct volume and NIHSS, and may be relevant to mitigate outcome differences in patients with stroke by aiding treatment decisions that rely on the NIHSS.
Concurrent acute brain infarcts in patients with monocular visual loss
The frequency of acute brain infarcts on diffusion‐weighted imaging (DWI) in patients with monocular visual loss of presumed ischemic origin (MVL) is sought to determine.
Adult cervicocerebral artery dissection: a single‐center study of 301 Finnish patients
This data indicates that there are only few small studies assessing potential risk factors, comorbidity, and prognostic factors in adult spontaneous cervicocerebral artery dissection (CAD) and these studies need to be investigated further.
Extensive Leukoaraiosis Is Associated With High Early Risk of Recurrence After Ischemic Stroke
The extent of leukoaraiosis independently predicts 90-day recurrent stroke risk after ischemic stroke, which suggests that leukoARaiosis may be used for risk stratification in isChemic stroke.
Atrial fibrillation is associated with anterior predominant white matter lesions in patients presenting with embolic stroke
AF is associated with specific WMH lesion pattern among patients with embolic stroke aetiology, suggesting that the link between AF and brain injury extends beyond thromboembolic complications to include a cardiovasculopathy that affects the brain and can be detected and characterised by WMH.
Atrial Fibrillation Is Associated With a Worse 90-Day Outcome Than Other Cardioembolic Stroke Subtypes

AF is associated with an unfavorable 90-day outcome among patients with a CES independent of established risk factors and initial stroke severity, which suggests that AF-specific mechanisms affect CES severity and functional status after CES.
Marchiafava–Bignami disease: two cases with favourable outcome

The incidence of Marchiafava–Bignami disease may be higher and its prognosis may be milder than generally believed, and non‐specific general symptoms and encephalopathy in an alcoholic may harbour undiagnosed MBD.
