Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 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:

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's quite disgusting that this information is not available from every stroke association and doctors group.

Early Prediction of Delayed Ischemia and Functional Outcome in Acute Subarachnoid Hemorrhage - Role of Diffusion Tensor Imaging

Who the fuck cares about predicting recovery? The non-negotiable goal is 100% recovery for all stroke survivors. Research dollars could be much better spent getting patients recovered.

Abstract

Background and Purpose—Diffusion tensor imaging (DTI) parameters are markers of cerebral lesion in some diseases. In patients with acute subarachnoid hemorrhage (SAH), we investigated whether DTI parameters measured at <72 hours might be associated with delayed cerebral ischemia (DCI) and with poor functional outcome at 3 months (modified Rankin Scale score ≥3).
Methods—DTI was performed in a prospective cohort of 60 patients with nontraumatic SAH at <72 hours. Association of fractional anisotropy and apparent diffusion coefficient values at <72 hours with the occurrence of DCI and outcome at 3 months was evaluated with logistic regression models, adjusting for known predictors of prognosis.
Results—At <72 hours after SAH, fractional anisotropy values at the cerebellum were associated with DCI occurrence (78% less odds of DCI for each 0.1 increase in fractional anisotropy; P=0.019). Early apparent diffusion coefficient values were not associated with DCI. After adjusting for confounding variables, an increase of 10 U in apparent diffusion coefficient at the frontal centrum semiovale corresponded to 15% increased odds of poor outcome (P=0.061).
Conclusions—DTI parameters at <72 hours post-SAH are independently associated with the occurrence of DCI and functional outcome. These preliminary results suggest the role of DTI parameters as surrogate markers of prognosis in nontraumatic SAH.
