The takeaway I get from this is that the injury from stroke lasts a hell of a lot longer than any neurologist is willing to tell you. And they don't even know how to quantify it.

After a mild concussion, special brain
scans show evidence of brain abnormalities four months later, when
symptoms from the concussion have mostly dissipated, according to
research published in the November 20, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.
“These results suggest that there are potentially two different modes of
recovery for concussion, with the memory, thinking and behavioral
symptoms improving more quickly than the physiological injuries in the
brain,” said study author Andrew R. Mayer, PhD, of the Mind Research
Network and University of New Mexico School of Medicine in Albuquerque.
Mayer further suggests that healing from concussions may be similar to
other body ailments such as recovering from a burn. “During recovery,
reported symptoms like pain are greatly reduced before the body is
finished healing, when the tissue scabs. These finding may have
important implications about when it is truly safe to resume physical
activities that could produce a second concussion, potentially further
injuring an already vulnerable brain.”
Mayer noted that standard brain scans such as CT or MRI would not pick
up on these subtle changes in the brain. “Unfortunately, this can lead
to the common misperception that any persistent symptoms are
psychological.”
The study compared 50 people who had suffered a mild concussion to 50
healthy people of similar age and education. All the participants had
tests of their memory and thinking skills and other symptoms such as
anxiety and depression two weeks after the concussion, as well as brain
scans. Four months after the concussion, 26 of the patients and 26
controls repeated the tests and scans.
The study found that two weeks after the injury the people who had
concussions had more self-reported problems with memory and thinking
skills, physical problems such as headaches and dizziness, and emotional
problems such as depression and anxiety than people who had not had
concussions. By four months after the injury, the symptoms were
significantly reduced by up to 27 percent.
The people who had concussions also had evidence of abnormalities in the
gray matter in the frontal cortex area of both sides of the brain,
based on the diffusion tensor imaging scans. The increase equated to
about 10 percent compared to the healthy people in the study. These
abnormalities were still apparent four months after the concussion. In
contrast, there was no evidence of cellular loss on scans.
Mayer said possible explanations for the brain abnormalities could be
cytotoxic edema, which results from changes in where fluids are located
in and around brain cells, or reactive gliosis, which is the change in
glial cells’ shape in response to damage to the central nervous system.
The study was supported by the National Institutes of Health.

neurologist is a doctor with specialized training in diagnosing,
treating and managing
disorders of the brain and nervous system such as
Alzheimer’s disease, stroke, migraine, multiple sclerosis, concussion,
Parkinson’s disease and epilepsy.

Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 29,112 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
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.
