Risk factors for aneurysmal sub-arachnoid haemorrhage can be divided into environmental and inherited factors; the latter being presumed more important in young patients. We explored in young sub-arachnoid haemorrhage patients whether risk-factor profiles influence clinical and radiological characteristics of aneurysms and sub-arachnoid haemorrhage. ⋯ Young sub-arachnoid haemorrhage patients without atherogenic risk factors are rare. Clinical and radiological characteristics vary between sub-arachnoid haemorrhage patients with different risk-factor profiles. This clinical heterogeneity should be taken into account in future genetic and other etiological studies.

The clinical diagnosis of transient ischemic attack is highly subjective, and the risk prediction after transient ischemic attack using the clinical parameters still remains unsatisfactory. ⋯ Approximately three-quarter of transient ischemic attack is associated with multimodal magnetic resonance imaging abnormality. Initial perfusion-weighted imaging abnormality predicts newly developed diffusion-weighted imaging lesions, and symptomatic magnetic resonance angiogram abnormality seems to be the most important predictor for subsequent clinical events. Multimodal magnetic resonance imaging appears to be useful in assessing transient ischemic attack and predicting outcome in these patients.

Reliable epidemiological data on the true incidence of cerebrovascular events related to spontaneous cervical artery dissection, including stroke and transient ischemic attack, are scarce. ⋯ The incidence of cerebrovascular events related to vertebral artery dissection is greater than previously reported, which may indicate a better identification of patients due to improvements in diagnostic procedures.

Randomized Controlled Trial Multicenter Study
Dual antiplatelets reduce microembolic signals in patients with transient ischemic attack and minor stroke: subgroup analysis of CLAIR study.
Short course of dual antiplatelet therapy for early secondary prevention is a promising treatment for patients with minor stroke or transient ischemic attack at high risk of recurrence. ⋯ Early dual therapy with clopidogrel and aspirin reduces microembolic signals in patients with minor ischemic stroke or transient ischemic attack, without causing significant bleeding complications.

The ASTRAL score was recently shown to reliably predict three-month functional outcome in patients with acute ischemic stroke. ⋯ The addition of information derived from multimodal imaging does not increase ASTRAL score's accuracy to predict functional outcome despite having an independent prognostic value. More selected radiological parameters applied in specific subgroups of stroke patients may add prognostic value of multimodal imaging.
