Deans' stroke musings: Scientists uncover a sleep-brain connection that could be the key to halting cognitive decline

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.

Scientists uncover a sleep-brain connection that could be the key to halting cognitive decline

Your incompetent? doctor missed this well over a decade ago, right? Why don't you get them fired? There are no excuses for such massive incompetence!

Scientists uncover a sleep-brain connection that could be the key to halting cognitive decline

The study monitored and recorded the brain activity of mice through electrode brain implants. Researchers stimulated neurons located in the hypothalamus, including the growth-hormone-releasing hormone (GHRH) neurons and two types of somatostatin neurons responsible for the regulation of the growth hormone release during the sleep-wake cycle.

Once those hormones are released, they increase activity in the brainstem region that affects attention, arousal, and cognition. This region, called the locus coeruleus, has also been associated with several neurological and psychiatric issues, such as PTSD and depression.

In this study, researchers found that GHRH stimulates growth hormone release while somatostatin suppresses it, essentially functioning like an accelerator and brake system in the brain. They also discovered that these peptides behave differently in REM and non-REM sleep states. During a non-REM state, somatostatin levels dropped while GHRH activity rose, promoting growth hormone release. “This suggests that sleep and growth hormone form a tightly balanced system: Too little sleep reduces growth hormone release, and too much growth hormone can in turn push the brain toward wakefulness,” said Daniel Silverman, a postdoctoral fellow at UC Berkeley and a co-author of the study.

Eventually, this finding could help researchers better understand and potentially develop treatments for various conditions, including sleep disorders, degenerative diseases like Parkinson’s and Alzheimer’s, and even metabolic conditions like diabetes.

“Sleep drives growth hormone release, and growth hormone feeds back to regulate wakefulness, and this balance is essential for growth, repair, and metabolic health,” Silverman said.
