Silent StrokeSilent Cerebral Infarct4 moreThe CBI registry is a prospective, interdisciplinary, multimodal observational registry of patients with covert brain infarction. Methods: A standardized workup in analogy to manifest ischemic stroke including cerebral MRI, long-term rhythm monitoring (3 x 7 days ECG), echocardiography, laboratory work-up and risk factor assessment as well as noninvasive angiography of the cervical and intracranial arteries will be performed.
Searching for Explanations for Cryptogenic Stroke in the Young: Revealing the Etiology, Triggers,...
Brain InfarctionIschemic Stroke3 moreBACKGROUND: In industrialized countries a considerable and increasing proportion of strokes occur at younger ages. Stroke at young age causes marked disability at worst and thus long-standing socioeconomic consequences and exposes survivors for 4-fold risk of premature death compared with background population. Up to 50% of young patients with ischemic stroke remain without definitive etiology for their disease despite extensive modern diagnostic work-up (i.e. cryptogenic stroke). The group of cryptogenic strokes includes those with patent foramen ovale (PFO) or other abnormalities in the atrial septum in the heart as the only or concomitant finding. Population prevalence of PFO is high, 25%, and the mechanisms how PFO would be associated causally with ischemic stroke remain to be clarified. Moreover, there are only scarce data on clinical outcome, long-term risk of new vascular events, and prevention of such events in these patients. DESIGN: Searching for Explanations for Cryptogenic Stroke in the Young: Revealing the Etiology, Triggers, and Outcome (SECRETO) is an international prospective multicenter case-control study of young adults (age 18-49) presenting with an imaging-positive first-ever ischemic stroke of undetermined etiology (aim N=2000). Patients are included after standardized diagnostic procedures (brain MRI, imaging of intracranial and extracranial vessels, cardiac imaging, and screening for coagulopathies) and age- and sex-matched to healthy controls in a 1:1 fashion. Up to 45 study sites worldwide will be needed to recruit the planned participant population during a 3-year period. Neurovascular imaging and echocardiography studies, and ECGs will be read centrally. AIMS: SECRETO involves five principal fields of investigation: (1) Stroke triggers and clinical risk factors; (2) Long-term prognosis (new vascular events, functional and psychosocial outcomes); (3) Abnormalities of thrombosis and hemostasis; (4) Biomarkers of e.g. inflammation, atherogenesis, endothelial function, thrombosis, platelet activation, and hemodynamic stress to characterize postulated cryptogenic stroke mechanisms; and (5) genetic study, including genome-wide association and candidate gene studies as well as next-generation sequencing approach. All analyses consider cardiac functional and interatrial structural properties as a possible mediator. Furthermore, SECRETO Family Study (substudy) aims at collecting extensive family history of thrombotic events from informative patients being screened for SECRETO main study and collect genetic samples from all consenting family members for whole-genome sequencing. SIGNIFICANCE: SECRETO will provide novel information on clinical and subclinical risk factors, both transient and chronic, predisposing to cryptogenic ischemic stroke in young adults. This study also reveals long-term prognosis of this understudied patient population and may discover new genetic background underlying the disease mechanism and provide potential targets for drug development.
Safety and Long-term Effectiveness of High Frequency Repetitive Transcranial Magnetic Stimulation...
Nervous System DiseasesStroke3 moreThe aim of the study is to determine if 2-week repetitive transcranial magnetic stimulation at the subacute phase of stroke (between day 7 and day 14) improves significantly arm motility at 3 months with remaining effect at one year, without significant adverse effect.

Brain InfarctionBrain IschemiaOverall goal of this study is to determine if transcranial direct current stimulation (tDCS) plus conventional occupational therapy improves functional motor recovery in the affected arm-hand in patients after an acute ischemic stroke compared to sham tDCS plus conventional occupational therapy, and to obtain information to plan a large randomized controlled trial.
Telerehabilitation With Aims to Improve Lower Extremity Recovery Post-Stroke

Arm Rehabilitation Study After Stroke
StrokeBrain Infarction3 moreThis study is about arm and hand recovery after a stroke. The investigators are testing an experimental arm therapy called Accelerated Skill Acquisition Program (ASAP) which combines challenging, intensive and meaningful practice of tasks of the participant's choice compared to two standard types of therapy (usual and customary arm therapy totaling 30 hours and usual and customary arm therapy for a duration indicated on the therapy prescription). A second objective is to characterize current outpatient arm therapy (dosage & content) following stroke for individuals who are eligible for ICARE. Eligible candidates must have had a stroke affecting an arm within the last 106 days.
Effect of Dipeptidyl-4 Inhibitors in Reducing Stroke Severity, From HIRA Database
Cerebral InfarctionInfarction2 moreThe goal of this observational study is to compare severity and mortality rates of acute cerebral infarction(requiring thrombolysis or endovascular recanalization) depending on the type of oral antidiabetic drug taken before the onset of cerebral infarction. Researchers will compare the group that used DPP-4 inhibitors as anti-diabetic drugs before cerebral infarction and the group that did not use them to see the effect of DPP-4 inhibitors in reducing severity of cerebral infarction.
