COAST Study - Cholesterol Optimization After Stroke

This study (acronym COAST Trial) is a multicenter observational registry aiming to document: patients' adherence and persistence to lipid-lowering therapy prescribed for secondary prevention; the proportion of patients achieving LDL cholesterol therapeutic targets at 3 months; the incidence of cerebrovascular recurrence and mortality at 90 days, as well as the occurrence of any adverse effects from these therapies. This information will provide a snapshot of post-stroke/TIA lipid-lowering management across centers and identify areas for improvement, offering useful data to optimize secondary prevention strategies in everyday clinical practice.

PLatform Study for INTracerebral Haemorrhage (PLINTH): Community-based Feasibility Study

The goal of this observational study is to answer three uncertainties about the design of a platform study for adults with stroke due to intracerebral haemorrhage. The main things the investigators aim to find out are: * The acceptability of a platform trial and its comparisons to brain haemorrhage survivors or their carers, and their clinicians. * Estimates of eligibility, willingness to participate, diversity, representativeness, adherence, retention, data completion, and event rates of intermediate and clinical outcomes over time for each comparison. * The most efficient platform trial design considering the findings of this feasibility study. Participants, or their welfare guardian, welfare attorney, or nearest relative will: * Watch a video informing them about the study * Read written information about the study * Provide informed consent * Permit collection of demographic and clinical details * Provide information in interviews at \~3 and \~14 days after the onset of the stroke

High Risk of Death or Disability in Brain Hemorrhage: Role of Spot Sign and Secondary Markers

This study looks at patients with brain hemorrhage to see if a special sign on brain scans, called the "Spot Sign," combined with other scan features, can predict a higher risk of death or disability. By comparing patient outcomes with existing prediction scores, the study aims to understand whether these scan markers provide extra value in identifying patients at higher risk.

Brain PERfusion Evaluation by Contrast-Enhanced UltraSound

The objective of the study is to assess brain tissue perfusion by contrast-enhanced ultrasound perfusion imaging (PerCEUS) in acute brain injuries. More precisely, it aims : * to evaluate the heterogeneity of brain perfusion and thus diagnose brain tissue hypoperfusion with contrast-enhanced ultrasound. * to correlate contrast-enhanced ultrasound with perfusion measurements by usual multimodal monitoring.

Neurologic Stem Cell Treatment Study

This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/

Descriptive Study on MRI Contrast of Acute Cerebral Hemorrhage in Different Microangiopathies

Cerebral haemorrhage represents a minority of acute vascular syndromes (less frequent than ischemic stroke, at around 20%), but with a therapeutic impasse, having no specific treatment. Arterial contrast ("spot sign") within the hematoma has been described in CT scans as a risk factor for further enlargement and poor prognosis. An equivalent marker has also been described in gadolinium-enhanced MRI. By studying the radiological appearance of gadolinium "spot signs" on MRI, which has better parenchymal resolution, the researchers propose to retrace the phenomenology of the acute phase of cerebral hemorrhage in order to better estimate the risk of radiological aggravation by subgroup, which could serve as a target population for future therapeutic trials.

Active Removal of IntraCerebral Hematoma Via Active Irrigation

Study evaluating if active irrigation by IRRAflow® with infusion of tPA will reduce the time needed for clearance of intracerebral and intraventricular hemorrhage compared with passive drainage.
