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.

Small 'window of opportunity' for best recovery after stroke

 That is just a convenient excuse for your medical team.  Don't allow that to ever  be used on you. Your doctor and hospital have known of this problem for decades and DONE NOTHING! Demand your doctor provide 100% recovery protocols.

Small 'window of opportunity' for best recovery after stroke

An international study has shown, for the first time, that the capacity of the human brain to recover and rewire itself peaks around two weeks after a stroke and diminishes over time.

The finding, published today in the Neurorehabilitation and Neural Repair journal, is the result of a study in London and Adelaide that followed the recovery of 60 stroke patients up to one year after their stroke.

Lead author Dr Brenton Hordacre, from the University of South Australia, says the multi-site study showed conclusive evidence that the brain only has a small window of opportunity to more easily repair itself after stroke.

"Earlier animal studies suggested this was the case, but this is the first time we have conclusively demonstrated this phenomenon exists in humans," Dr Hordacre says.

The researchers scanned the brains of stroke survivors as they recovered over 12 months. They found that in the initial days following an ischemic stroke (caused by a blocked artery to the brain), the brain has a greater capacity to modify its neural connections and its plasticity is increased.

"It is during this early period after stroke that any physiotherapy is going to be most effective because the brain is more responsive to treatment.

"Earlier experiments with rats showed that within five days of an ischemic stroke they were able to repair damaged limbs and neural connections more easily than if therapy was delayed until 30 days post stroke."

The researchers used continuous transcranial magnetic stimulation (cTBS) to repetitively activate different hemispheres of the motor cortex to measure brain plasticity.

The Adelaide laboratory tested the stroke damaged motor cortex, which is the main area that controls movement. The London laboratory tested the non-stroke damaged hemisphere which is also important to help recovery.

"Our assessments showed that plasticity was strongest around two weeks after stroke in the non-damaged motor cortex. Contrary to what we expected, there was no change in the damaged hemisphere in response to cTBS."

Dr Hordacre says the findings confirm the importance of initiating therapy as soon as possible after a stroke.

Current evidence indicates that less than eight minutes of daily therapy is dedicated to upper limb recovery within the first four weeks of a stroke.

"Delivering more treatment within this brief window is needed to help people recover after stroke.

"The next step is to identify techniques which prolong or even re-open a period of increased brain plasticity, so we can maximise recovery," Dr Hordacre says.
