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.
My back ground story is here:

Inhibition of Tnf-α R1 signaling can rescue functional cortical plasticity impaired in early post-stroke period

TNF is what Dr. Tobinick is supposedly treating using his proprietary method of injecting etanercept. Dr. Tobinick could have solved this TNF question years ago if he had only actually run clinical tests on etanercept.

Inhibition of Tnf-α R1 signaling can rescue functional cortical plasticity impaired in early post-stroke period 


Tumor necrosis factor-α (TNF-α) is one of the key players in stroke progression and can interfere with brain functioning. We previously documented an impairment of experience-dependent plasticity in the cortex neighboring the stroke-induced lesion, which was accompanied with an upregulation of Tnf-α level in the brain of ischemic mice 1 week after the stroke. Because TNF receptor 1 (TnfR1) signaling is believed to be a major mediator of the cytotoxicity of Tnf-α through activation of caspases, we used an anti-inflammatory intervention aimed at Tnf-α R1 pathway, in order to try to attenuate the detrimental effect of post-stroke inflammation, and investigated if this will be effective in protecting plasticity in the infarct proximity. Aged mice (12–14 months) were subjected to the photothrombotic stroke localized near somatosensory cortex, and immediately after ischemia sensory deprivation was introduced to induce plasticity. Soluble TNF-α R1 (sTNF-α R1), which competed for TNF-α with receptors localized in the brain, was delivered chronically directly into the brain tissue for the whole period of deprivation using ALZET Micro-Osmotic pumps. We have shown that such approach undertaken simultaneously with the stroke reduced the level of TNF-α in the peri-ischemic tissue and was successful in preserving the post-stroke deprivation-induced brain plasticity.
