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.

Left-side neglect may shed light on strokes

This is the kind of knowledge based research we need to understand strokes. And it comes from Australia. I had a slight case of this.  My theory on why I had a slight case of this is that the penumbra damage extended into the prefrontal cortex area. Your doctor should be required to explain why you have it and what to do about it.

An unusual condition that causes people to ignore the left sides of their bodies may help scientists better understand stroke recovery.

Unilateral spatial neglect is typically caused by strokes on the right hand side of the brain and manifests in patients ignoring the left side of their body.
People with the condition may ignore food on the left hand side of their plate or, if asked to draw a clock, squash all 12 numbers into the right side of the clock face, leaving the other side blank.
They may also fail to shave, or to put make-up on the left side of their faces and in severe cases, they behave as though the left side of their world does not exist.
“We know that brain plasticity plays a critical role in recovering from stroke,” says Professor Jason Mattingley, chair of cognitive neuroscience.
“The fact that people with spatial neglect tend to have poorer recovery of motor function suggested to us that attention may be important for guiding plasticity following stroke.”
Current research being undertaken by the Mattingley laboratory is exploring this link.
“What we’re trying to do is explore what effect attention has on brain plasticity, and how attention might be used in neurorehabilitation” says Mattingley.
Volunteers first undergo a magnetic resonance imaging (MRI) scan, which provides researchers with a three-dimensional picture of the brain.
“In terms of their structure, brains are like fingerprints—no two are exactly the same, even though superficially they seem very similar,” Mattingley explains.
The MRI scan allows researchers to guide a transcranial magnetic stimulation (TMS) coil into position upon a volunteer’s scalp.
The device induces a small electrical current in the underlying brain tissue, causing it to become more active. The researchers specifically target a part of the motor cortex that controls the thumb muscle in the left hand.
“It’s well established that the more often neurons activate at the same time, the more likely they are to communicate efficiently in the future. This is how the brain learns,” says Mattingley.
“We’re exploiting that general principle in this research.”
Marc Kamke, research fellow at QBI explains: “By adjusting the type of brain stimulation delivered we can artificially induce short-term changes that resemble naturally-occurring plasticity.”
But what the researchers have found is that the effects of stimulation upon a brain’s plasticity are dependent on attention.
“When we ask people to undertake a visual task that is irrelevant to the brain stimulation, but that demands a great deal of their attention, we observe a reduction in plasticity,” Kamke explains.
“When the task does not require much attention, however, the brain’s plastic response is apparent.”
“These results show that attention plays an important role in guiding brain plasticity,” says Mattingley.
He adds, “while practical applications remain several steps away, this knowledge may ultimately help us develop more effective strategies for physical therapy after stroke.”
The results of the research, which was funded by the National Health and Medical Research Council of Australia, are published this week in The Journal of Neuroscience.
