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.

Sense of smell key to predicting recovery after brain injury, say scientists

Obviously it is your responsibility to be able to do this while in a locked-in state otherwise you may be cut off from rehab. Not your doctor's responsibility, YOURS.  You do know that this will never get to your hospital.

Sense of smell key to predicting recovery after brain injury, say scientists

Sense of smell may hold the key to predicting the recovery of people with severe brain injury, according to scientists.
A simple "sniff test", trialled by researchers at the University of Cambridge, could help doctors diagnose and determine treatment for patients who are in a vegetative state or have minimal consciousness following brain injuries.
Patients in a vegetative state can open their eyes, wake up and fall asleep regularly and have basic reflexes but don't show signs of awareness.

Minimally conscious patients can have periods where they can show signs of awareness or respond to commands.

'Sniff test'

"The accuracy of the sniff test is remarkable - I hope it will help in the treatment of severely brain injured patients around the world," said Dr Anat Arzi, a researcher in the University of Cambridge's Department of Psychology and the Weizmann Institute of Science Israel, who led the study.
Results published in the journal Nature revealed 100 per cent of patients who reacted to the sniff test went on to regain consciousness and more than 91 per cent of these patients were still alive three and a half years after injury.
Doctors often find it difficult to determine a patient's state of consciousness after a severe brain injury but accurate diagnosis is critical for treatment strategies, such as pain management, and for end-of-life decisions.
Sense of smell relies on structures deep within the brain and works whether we are awake or asleep.

Accurate diagnosis

The brain automatically changes the way we sniff in response to different smells, with shorter and shallower breaths for unpleasant smells.
Scientists carried out the ‘sniff test’ on 43 patients with severe brain injury, presenting them different jars of smell for five seconds.
One jar contained a pleasant smell of shampoo, one an unpleasant smell of rotten fish, and one had no smell at all.
Each jar was presented ten times in a random order and the volume of air sniffed by the patient was measured using a nasal cannula.

Researchers found minimally conscious patients inhaled significantly less in response to smells but did not discriminate between nice and nasty.
These patients also modified their nasal airflow in response to the jar with no smell, suggesting they were aware of the jar or anticipated a smell.
Vegetative state patients had a more varied response, some did not change their breathing in response to the smells but others did.
A follow-up investigation three and a half years later found more than 91% of the patients who had a sniff response shortly after injury were still alive, but 63% of those who had showed no response had died.

Sniff response

"We found that if patients in a vegetative state had a sniff response, they later transitioned to at least a minimally conscious state”, said Dr Arzi, “In some cases, this was the only sign that their brain was going to recover - and we saw it days, weeks and even months before any other signs.”
Dr Tristan Bekinschtein, from the University of Cambridge's Department of Psychology who was also involved in the study, said:"This new and simple method to assess the likelihood of recovery should be immediately incorporated in the diagnostic tools for patients with disorders of consciousness."
