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.

IL1B and VWF Variants Are Associated With Fibrinolytic Early Recanalization in Patients With Ischemic Stroke

At least they are trying to find out why tPA doesn't work.

Abstract

Background and Purpose—There is a great interindividual variability among patients with acute ischemic stroke regarding the response to intravenous tissue-type plasminogen activator treatment. The aim of this study was to identify genetic variants associated with recanalization, and thus treatment efficacy, after tissue-type plasminogen activator administration.
Methods—A total of 140 single nucleotide polymorphisms from 97 candidate genes were successfully genotyped by SNPlex in 2 cohorts, accounting for 497 prospectively recruited tissue-type plasminogen activator-treated patients, of whom 33% recanalized during tissue-type plasminogen activator infusion. Functional studies were then performed, including assessment of interleukin 1B mRNA levels and von Willebrand factor, FIII, FVII, FVIII, and FX protein activity.
Results—After replication, the following single nucleotide polymorphisms were associated with early recanalization: rs1143627 in IL1B gene (CC: 53.1% of recanalization, A-carriers: 32.7%; P=0.022; replication cohort: P=0.046), rs16944 in IL1B gene (AA: 50% of recanalization, G-carriers: 32%; P=0.038; replication cohort: P=0.049), and rs1063856 in the vWF gene (GG: 53.8% of recanalization, A-carriers: 31.5%; P=0.006; replication cohort: P=0.046). The functional studies revealed an association between the rs1063856 single nucleotide polymorphisms in vWF and FVIII activity (AA: 115.93%, AG: 156.07%, GG: 83.42%; P=0.005).
Conclusions—Three single nucleotide polymorphisms were associated with tissue-type plasminogen activator efficacy in the Spanish population, and their mechanism of action might be associated with the activity of coagulation factors.
