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:

The neuroprotective compound P7C3-A20 promotes neurogenesis and improves cognitive function after ischemic stroke

How many decades will it take before followup studies are done in humans? I'm guessing never because we have fucking failures of stroke associations and NO stroke strategy or stroke leadership. Or you just could hire your own researchers to test this out.

The neuroprotective compound P7C3-A20 was proposed as a therapeutic for stroke.
P7C3-A20 reduced sensorimotor and cognitive deficits that occur after stroke.
P7C3-A20 significantly increased neurogenesis in both neurogenic niches.
P7C3-A20 significantly reduced both hippocampal and cortical atrophy which was strongly correlated to tissue sparing.
P7C3-A20 treatment enhanced flux of nicotinamide adenine dinucleotide.


Ischemic stroke is a devastating condition with few therapeutic interventions available. The neuroprotective compound P7C3-A20 inhibits mature neuronal cell death while also increasing the net magnitude of postnatal neurogenesis in models of neurodegeneration and acute injury. P7C3 compounds enhance flux of nicotinamide adenine dinucleotide (NAD) in mammalian cells, a proposed therapeutic approach to treating cerebral ischemia. The effectiveness of P7C3-A20 treatment on chronic histopathological and behavioral outcomes and neurogenesis after ischemic stroke has not previously been established. Here, a transient middle cerebral artery occlusion in rats was followed by twice daily injection of P7C3-A20 or vehicle for 7 days. P7C3-A20-treated rats performed significantly better than vehicle-treated controls in sensorimotor cylinder and grid-walk tasks, and in a chronic test of spatial learning and memory. These behavioral improvements with P7C3-A20 treatment were correlated with significantly decreased cortical and hippocampal atrophy, and associated with increased neurogenesis in the subventricular zone and hippocampal dentate gyrus subgranular zone. Furthermore, cerebral ischemia significantly reduced NAD in the cortex but P7C3-A20 treatment restored NAD to sham levels. Thus, P7C3-A20 treatment mitigates neurodegeneration and augments repair in the brain after focal ischemia, which translates into chronic behavioral improvement. This suggests a new therapeutic approach of using P7C3 compounds to safely augment NAD and thereby promote two independent processes critical to protecting the brain from ischemic stroke: mature neuron survival and postnatal hippocampal neurogenesis throughout the post-ischemic brain.
