Review Meta Analysis
MRI lesions as a surrogate for relapses in multiple sclerosis: a meta-analysis of randomised trials.
A meta-analysis of randomised trials in relapsing-remitting multiple sclerosis published in 2009 showed a quantitative relation between the treatment effects detected on MRI lesions and clinical relapses. We aimed to validate that relation using data from a large and independent set of clinical trials in multiple sclerosis. ⋯ None.

Review Meta Analysis
Treatment of acute ischaemic stroke with thrombolysis or thrombectomy in patients receiving anti-thrombotic treatment.
Systemic thrombolysis with alteplase is the only approved medical treatment for patients with acute ischaemic stroke. Thrombectomy is also increasingly used to treat proximal occlusions of the cerebral arteries, but has not shown superiority over systemic thrombolysis with alteplase. Many patients with acute ischaemic stroke are pretreated with antiplatelet or anticoagulant drugs, which can increase the bleeding risk of thrombolysis or thrombectomy. ⋯ Almost no data are available for the safety of alteplase in patients with atrial fibrillation who have been given novel oral anticoagulants (NOAC) for stroke prevention. Some coagulation parameters could help to identify patients treated with NOAC who might be eligible for thrombolysis. Thrombectomy can be done in patients given antiplatelets and probably in those given anticoagulants; however, conclusions about anticoagulants are based on findings from observational studies with small patient numbers.

Vestibular migraine is becoming recognised as a distinct clinical entity that accounts for a high proportion of patients with vestibular symptoms. A temporal overlap between vestibular symptoms, such as vertigo and head-movement intolerance, and migraine symptoms, such as headache, photophobia, and phonophobia, is a requisite diagnostic criterion. ⋯ The pathophysiology of vestibular migraine is incompletely understood but plausibly could include neuroanatomical pathways to and from central vestibular structures and neurochemical modulation via the locus coeruleus and raphe nuclei. In the absence of controlled trials, treatment options for patients with vestibular migraine largely mirror those for migraine headache.

Spinocerebellar ataxias (SCAs) are autosomal, dominantly inherited, fully penetrant neurodegenerative diseases. Our aim was to study the preclinical stage of the most common SCAs: SCA1, SCA2, SCA3, and SCA6. ⋯ ERA-Net E-Rare and Polish Ministry of Science and Higher Education.
