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.

Exercise interventions in individuals with Parkinson's disease incorporate goal-based motor skill training to engage cognitive circuitry important in motor learning. With this exercise approach, physical therapy helps with learning through instruction and feedback (reinforcement) and encouragement to perform beyond self-perceived capability. ⋯ Exercises that incorporate goal-based training and aerobic activity have the potential to improve both cognitive and automatic components of motor control in individuals with mild to moderate disease through experience-dependent neuroplasticity. Basic research in animal models of Parkinson's disease is beginning to show exercise-induced neuroplastic effects at the level of synaptic connections and circuits.

Mutant mouse models suggest that the chloride channel ClC-2 has functions in ion and water homoeostasis, but this has not been confirmed in human beings. We aimed to define novel disorders characterised by distinct patterns of MRI abnormalities in patients with leukoencephalopathies of unknown origin, and to identify the genes mutated in these disorders. We were specifically interested in leukoencephalopathies characterised by white matter oedema, suggesting a defect in ion and water homoeostasis. ⋯ European Leukodystrophies Association, INSERM and Assistance Publique-Hôpitaux de Paris, Dutch Organisation for Scientific Research (ZonMw), E-Rare, Hersenstichting, Optimix Foundation for Scientific Research, Myelin Disorders Bioregistry Project, National Institute of Neurological Disorders and Stroke, and Genetic and Epigenetic Networks in Cognitive Dysfunction (GENCODYS) Project (funded by the European Union Framework Programme 7).
