Many international guidelines on the prevention of venous thromboembolism recommend targeting heparin treatment at patients with stroke who have a high risk of venous thrombotic events or a low risk of haemorrhagic events. We sought to identify reliable methods to target anticoagulant treatment and so improve the chance of avoiding death or dependence after stroke. ⋯ MRC.

Movement disorders can occur as primary (idiopathic) or genetic disease, as a manifestation of an underlying neurodegenerative disorder, or secondary to a wide range of neurological or systemic diseases. Cerebrovascular diseases represent up to 22% of secondary movement disorders, and involuntary movements develop after 1-4% of strokes. ⋯ Some of these disorders occur immediately after acute stroke, whereas others can develop later, and yet others represent delayed-onset progressive movement disorders. These movement disorders have been encountered in patients with ischaemic and haemorrhagic strokes, subarachnoid haemorrhage, cerebrovascular malformations, and dural arteriovenous fistula affecting the basal ganglia, their connections, or both.

Early recanalisation and an increase in collateral blood supply are predictors of favourable outcome in acute ischaemic stroke. Since individual responses to intravenous treatment with alteplase are heterogeneous, additional intra-arterial thrombolytic and mechanical endovascular treatment is increasingly given. ⋯ Although neuroprotective agents have not shown benefit in clinical trials, non-pharmacological treatment strategies-such as decompressive surgery, therapeutic hypothermia, transcranial laser treatment, or augmentation of cerebral collateral perfusion by different means (eg, partial aortic occlusion or sphenopalatine ganglion stimulation)-are topics of current research. The future of acute stroke therapy relies on evidence for individually tailored, effective, safe, and rapidly accessible treatment probably consisting of combined pharmacological and improved non-pharmacological approaches.
