Deans' stroke musings: Chew On This: Reduced Mastication Impairs Memory and Learning Function

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.

Chew On This: Reduced Mastication Impairs Memory and Learning Function

Well shit this was written about in April 2016, why repeat the research?

The impact of mastication on cognition: evidence for intervention and the role of adult hippocampal neurogenesis April 2016

No chewing because of swallowing problems? I bet chewing gum would work,

Summary: Researchers find changes in masticatory stimuli can modulate neurogenesis and hippocampal function. Published in the Journal of Dental Research, findings reveal reduced mastication impaired learning and memory function in mice.

According to researchers, the frequency of mastication has dramatically decreased along with changes in dietary habits. Masticatory stimulation has influence on the development of the central nervous system as well as the growth of maxillofacial tissue in children. Deterioration of masticatory function due to aging and the consequent reduction of brain function has become major problems. Although the relationship between mastication and brain function is potentially important, the mechanism underlying is not fully understood.
In order to prevent brain function disorders, including those relating to memory and learning, it is an urgent task to elucidate the linkage between masticatory function and brain function.
Researchers found that growth of the maxillofacial bone and muscle were suppressed in mice with reduced masticatory stimuli by feeding with powder food. In addition, behavioral experiments revealed that reduced mastication impaired memory and learning functions. In the hippocampus, a major component responsible for memory, neural activity, synapse formation and expression of brain-derived neurotrophic factor (BDNF) were reduced in these mice .
Thus, the authors demonstrated that the changes in masticatory stimuli can modulate neurogenesis and neuronal activity in the hippocampus, functionally contributing to cognitive function.
This research suggests that maintaining or strengthening of masticatory function would be effective in preventing dementia and memory/learning dysfunction. It is also suggested that further elucidation of the mechanism linking mastication and brain function can lead to novel treatments and preventive measures for memory/learning dysfunction in the future.
