Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Ultra-Sensitive Molecular MRI of Vascular Cell Adhesion Molecule-1 Reveals a Dynamic Inflammatory Penumbra After Strokes

Read the conclusion paragraph and demand to know that means from your neurologist.

Abstract

Background and Purpose—Our aim was to assess the spatiotemporal evolution of the cerebrovascular inflammation occurring after ischemic and hemorrhagic strokes using a recently developed, fast, and ultra-sensitive molecular MRI method.
Methods—We first assessed longitudinally the cerebrovascular inflammation triggered by collagenase-induced hemorrhage and by permanent/transient middle cerebral artery occlusion in mice, using MRI after injection of microparticles of iron oxide targeted to vascular cell adhesion molecule-1 (MPIOs-αVCAM-1). Thereafter, we used this method to study the anti-inflammatory effects of celecoxib, atorvastatin, and dipyridamole after stroke.
Results—Using multiparametric MRI, we demonstrated that the level and the kinetics of cerebrovascular VCAM-1 expression depend on several parameters, including stroke pathogenesis, the natural history of the disease, and the administration of inflammation-modulating drugs. Interestingly, in transient middle cerebral artery occlusion and intracranial hemorrhage models, VCAM-1 expression was maximal at 24 hours and almost returned to baseline 5 days after stroke onset. In contrast, after permanent middle cerebral artery occlusion, VCAM-1 overexpression was sustained between 24 hours and 5 days, and was particularly significant in the peri-infarct areas. Our results suggest that these perilesional areas expressing VCAM-1 constitute an inflammatory penumbra that is recruited by the ischemic core during the subacute phase. Using MPIOs-αVCAM-1–enhanced imaging, we also provided evidence that celecoxib and atorvastatin (but not dipyridamole) alleviate VCAM-1 overexpression after stroke and prevent formation of the inflammatory penumbra.
Conclusions—MPIOs-αVCAM-1–enhanced imaging seems to be promising in the detection of individuals presenting with severe cerebrovascular responses after stroke, which could therefore benefit from anti-inflammatory treatments.
