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.

Study finds continued birth of new neurons (neurogenesis) well into our 70s

Does this refute this research from March 2018? What is your doctors' protocol to create neurogenesis? Or are your doctors sitting on their asses waiting for SOMEONE ELSE TO SOLVE THE PROBLEM?

Human hippocampal neurogenesis drops sharply in children to undetectable levels in adults March 2018

Study finds continued birth of new neurons (neurogenesis) well into our 70s

___
Well into our 70s, we con­tin­ue to devel­op new cells in an area of the brain respon­si­ble for new mem­o­ries and explo­ration of new envi­ron­ments, sci­en­tists report.
These new brain cells sus­tain our abil­i­ties to make new mem­o­ries, learn, and cope with the envi­ron­ment, and they are impor­tant for emo­tion­al respons­es,” Dr. Mau­ra Boldri­ni from Colum­bia Uni­ver­si­ty in New York City told Reuters Health by email…Even the old­est brains pro­duced new brain cells. The num­ber of devel­op­ing and imma­ture brain cells remained sta­ble across the age range, the researchers report­ed in the jour­nal Cell Stem Cell.
There was, how­ev­er, a decline in the abil­i­ty of mature nerve cells to change their func­tion — a prop­er­ty known as neu­ro­plas­tic­i­ty — with increas­ing age… “We know that vas­cu­la­ture can become weak­er with aging, and we need to find ways to keep our (blood ves­sels) healthy so that our brain can remain more plas­tic,” Dr. Boldri­ni said. “This means that through healthy lifestyle, enriched envi­ron­ment, social inter­ac­tions, and exer­cise” — all of which help main­tain healthy blood ves­sels — “we can main­tain these neu­rons healthy and func­tion­ing and sus­tain healthy aging.”

The Study:

  • Sum­ma­ry: Adult hip­pocam­pal neu­ro­ge­n­e­sis declines in aging rodents and pri­mates. Aging humans are thought to exhib­it wan­ing neu­ro­ge­n­e­sis and exer­cise-induced angio­gen­e­sis, with a result­ing vol­u­met­ric decrease in the neu­ro­genic hip­pocam­pal den­tate gyrus (DG) region, although con­cur­rent changes in these para­me­ters are not well stud­ied. Here we assessed whole autop­sy hip­pocampi from healthy human indi­vid­u­als rang­ing from 14 to 79 years of age. We found sim­i­lar num­bers of inter­me­di­ate neur­al prog­en­i­tors and thou­sands of imma­ture neu­rons in the DG, com­pa­ra­ble num­bers of glia and mature gran­ule neu­rons, and equiv­a­lent DG vol­ume across ages. Nev­er­the­less, old­er indi­vid­u­als have less angio­gen­e­sis and neu­ro­plas­tic­i­ty and a small­er qui­es­cent prog­en­i­tor pool in ante­ri­or-mid DG, with no changes in pos­te­ri­or DG. Thus, healthy old­er sub­jects with­out cog­ni­tive impair­ment, neu­ropsy­chi­atric dis­ease, or treat­ment dis­play pre­served neu­ro­ge­n­e­sis. It is pos­si­ble that ongo­ing hip­pocam­pal neu­ro­ge­n­e­sis sus­tains human-spe­cif­ic cog­ni­tive func­tion through­out life and that declines may be linked to com­pro­mised cog­ni­tive-emo­tion­al resilience.
