Brain Vital Signs M-Score: Point-of-care Monitoring for Motor Recovery After Stroke
StrokeThe purpose of this study is to investigate brain signals relating to motor function, using electroencephalography (EEG) technology. The aims of the study can be separated into 3 specific study objectives: Record EEG data from control participants and individuals with stroke during basic motor tasks and build a database of EEG signals to enable analysis of motor control. Apply signal processing algorithms to extract EEG features related to motor control. Develop a framework/the motor score (M-Score) that uses the EEG signals, in combination with machine learning approaches, to quantify motor control ability.
China Stroke Secondary Prevention Trial
StrokeTransient Ischemic AttackThe CSSPT study is a multi-center, randomized, double blinded, placebo-controlled secondary stroke prevention trial in China to determine whether the addition of folic acid and vitamin supplements will reduce recurrent stroke events and other combined incidence of recurrent vascular events and vascular death.

Mechanisms of Stroke in Intracranial Stenosis
StrokeThe objective of this SAMMPRIS-affiliated study is to understand the mechanisms the mechanisms that underlie ischemic stroke recurrence in high-grade intracranial atherosclerotic disease in order to determine predictors of recurrent stroke. MoSIS will evaluate 6 specific mechanisms of stroke in the medically-treated SAMMPRIS cohort: decreased antegrade flow, progression of stenosis, decreased proximal collateral flow, decreased distal collateral flow, impaired cerebrovascular reserve, and artery-to-artery embolism.
ERILs Und SNILs Unter SOC
StrokeAcuteHow many ERILs occur in caucasian patients with LAA stroke during 7 days on standard treatment? How many SNILs occur between 7 and 30 days after acute ischemic event on standard treatment? How many of during acute event diagnosed lesions (ERILs) are (still) detectable after 30 days? Are there relevant risk faktors for the occurence of ERILs and SNILs (eg Diabetes or Biomarkers)?
Prognosis of a First-Ever Stroke in Persons Living With HIV
Cerebrovascular AccidentAcute1 moreWith aging of the persons living with HIV, cardiovascular diseases now account for substantial mortality and morbidity. Stroke frequency grows exponentially with aging and its incidence doubles every decade over 55 years of age. The prognosis of ischemic stroke depends mainly on the care in Stroke Units in the acute phase of the disease (thrombolysis/thrombectomy). It is important that HIV patients are referred to these units in the first hours of a stroke and not to their infectious disease units which is a loss of chance. It would also be important to know whether HIV patients need specific protocols for stroke emergency management. The study aims to compare the functional prognosis after the first occurrence of an ischemic stroke, in patients admitted to a Stroke Unit, whether they are infected or not infected by HIV.
Risk Factors of Conversion From Local to General Sedation in Endovascular Stroke Therapy
Acute StrokeThrombectomy is now the standard of care of revascularization in acute ischaemic stroke. Data tend to show that final neurologic outcome is superior if the thrombectomy procedure was performed under conscious sedation. The Rothschild Foundation is a high output centre with more than 400 thrombectomy procedures every year. We report a rate of 5% of these procedures requiring general anesthesia despite conscious sedation being the standard of care. This study aims to identify clinical factors associated with a risk of conversion of a conscious sedation to a general anesthesia.
The Influence of Exercise on Neuroplasticity and Motor Learning After Stroke
StrokeExercise1 moreParticipants will complete 11 sessions. These include screening, 5 sessions where exercise or rest (according to group assignment) are paired with practice of a motor task, MRI and Transcranial Magnetic Stimulation (TMS) before and after the intervention will be used to assess neuroplasticity (ability for the brain to reorganize and create new connections).
rTMS Posterior Parietal Cortex Modulation and Upper Limb Movement After Stroke
StrokeHemiparesis2 moreThis study evaluates the effect of a unique session of inhibitory rTMS (cTBS) over the contralesional posterio parietal cortex (PPC) on the spatio-temporal parameters of a pointing movement performed by stroke patients with their paretic upper limb. It will also assess the effects on the resting motor threshold of both hemispheres and on parietopremotor connectivity. To achieve theses aims, the real cTBS stimulation will be randomly counterbalanced with a SHAM stimulation (in a second session) in a crossover design. Assessments will be performed before and after each stimulation session.
Action Observation Treatment (AOT) as a Rehabilitation Tool
StrokeAcute Hemiplegia1 moreEpidemiological studies report that 85% of stroke survivors show hemiparesis and a percentage ranging from 55% to 75% report upper limb functional impairment. Early rehabilitation in stroke patients with motor disorders can be effective to restore the affected function and to improve the performance of daily activities. Up to now, different methods and techniques have been used to recover motor functions in stroke patients. However, none of these has been conclusively proven to be more effective than the others. The clinical benefits induced by motor rehabilitation are closely related to "neuroplasticity". The main aim of the present study is to assess the efficacy of action observation treatment, based on Mirror Neuron System (MNS), in the rehabilitation of upper limb motor functions in acute stroke patients. The study will also aim at assessing neuroplasticity within areas belonging to the MNS through functional magnetic resonance (fMRI).
