Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 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:

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's quite disgusting that this information is not available from every stroke association and doctors group.

Newly discovered scavenger brain cells could protect against stroke and dementia

Followup needed, but we have fucking failures of stroke associations that will do nothing with this information.

Lymphatic cells are the body’s garbage-disposal system: When fats and other waste products leak out of blood vessels, they mop them up so they don’t damage organs. These types of cells have not been seen in the brain, however, so scientists at the University of Queensland in Australia were surprised when they found a new type of lymphlike cell there.
By studying transparent zebrafish, the scientists observed scavenger cells surrounding the brain that clear out cellular waste. The cells are similar to "mato," or lipid-laden, cells in people, which were not previously known to be lymphatic, according to a press release. Ben Hogan, Ph.D., an associate professor in the university’s Institute for Molecular Bioscience, believes similar cells may be active in the human brain as well, protecting it against stroke and dementia by keeping harmful substances out.
Normally, lymphatic cells clump together, forming vessel-like structures that carry fluid, Hogan explained. But in zebrafish brains, “these cells exist individually, independent of vessels and collect waste that enter the brain from the bloodstream,” he said in the release.
Because zebrafish have many of the same cells and organs as people do, the discovery could enhance the study of brain disorders and treatments, Hogan added. The study was published in the journal Nature Neuroscience.
Zebrafish are being deployed in research for a range of diseases, from cancer to diabetes. Last year, scientists at Boston Children’s Hospital used the transparent creatures to visualize the spread of melanoma from a single cell, and in so doing identified genes involved in metastasis that they believe could be targets for new treatments. Researchers at the University of Oregon found a protein in zebrafish that seems to boost insulin production. And a team at Johns Hopkins has developed genetically modified zebrafish embryos that can be used in high-throughput screening for potential new drugs.
The University of Queensland team plans to expand upon their findings by studying how the cells they discovered function in people and how they influence neurological diseases such as stroke and dementia. They are also interested in learning whether existing drugs can directly control the scavenger cells in the brain, Hogan said.
