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.

Brain-training games don’t really train brains, a new study suggests

So what the hell is your doctors solution to prevent cognitive decline? DEMAND an answer.

Brain-training games don’t really train brains, a new study suggests


The first large study to rigorously examine brain-training games using cognitive tests and brain imaging adds to evidence that they are not particularly good at training brains and appear to have no more effect on healthy brains than video games. The study is another blow to companies such as Lumosity that have been accused of falsely claiming their programs can improve mental performance.
In a study published Monday in the Journal of Neuroscience, 128 young adults were tested for mental performance after playing either Lumosity brain-training games or regular video games for 10 weeks. Researchers saw no evidence that commercial brain-training leads to improvements in memory, decision-making, sustained attention or ability to switch between mental tasks.
In early 2016, Lumosity paid a $2 million fine to settle charges of misleading advertising. While its commercials boasted that Lumosity games are based on the science of neuroplasticity, the Federal Trade Commission and an open letter from 69 brain scientists insisted the research does not support claims that brain games make people smarter or stave off mental decline. While a study conducted by Lumosity in 2015 suggested that brain-training games improve performance on some mental tasks better than crossword puzzles do, other studies have shown no effect.
Caryn Lerman and Joseph Kable at the University of Pennsylvania were interested in whether brain-training games could help people control risky or impulsive behaviors. “You can predict using brain imaging data who will succeed and who will fail in an attempt to quit smoking,” Lerman explained. The “executive control network,” or ECN, is more active in those who will likely quit. The ECN is important for self-control, planning, and goal-setting. When we’re focused on a task and forming memories, the ECN is activated. When we begin to daydream, our “default mode network” takes over.
Other studies have suggested cognitive exercises such as brain games increase activity in the ECN, but few have shown translation of that increase into everyday activities.
“People who choose immediate rewards over long-term benefits are more likely to engage in risky behaviors,” said Lerman. To measure inclinations toward impulsive decisions in the study, researchers had volunteers rapidly make a series of hypothetical choices. For example, would they prefer to receive $20 now or $40 in a month? The answer seems like a no-brainer, but imagine if the question was instead: Should I eat a piece of cake now, or lose a pound this week? We make these kinds of decisions all the time, and our ECN is involved.

The researchers predicted that playing brain-training games that require memory and focus might activate the ECN of healthy young adults more than regular video games, leading to improved decision-making. Participants in the brain-training group played Lumosity computer games designed to improve mental skills like memory; for example, they would have to click on fish to feed them while making sure not to feed the same fish twice.
