[https://wakeup-world.com/2017/10/01/cannabis-the-ultimate-in-neuroprotection/|This article] refers to groundbreaking research about the neuroprotective  properties of different cannabinoids ( i e preventing the damage and death of brain cells like in dementia, ALS, Parkinsons):

~~#060:"mice modified to elicit the symptoms of Huntington’s disease. In the cell cultures they found THCA caused an increase in mitochondrial mass as well as reducing cell toxicity, while in the mice, __THCA improved their Huntington’s related restricted movement__, prevented striatal degeneration and reduced the inflammation caused by the disease."~~

~~#060:“… useful in the treatment and prophylaxis of wide variety of __oxidation associated diseases__, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in__ limiting neurological damage following ischemic insults__, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease and HIV dementia.”~~
~~#060:
"Not only that, but cannabinoids have been found to promote the holy grail of the healthy ageing brain, neurogenesis, or the growth of new brain cells. Research has shown the administration of plant cannabinoids promoted hippocampal neurogenesis – __new cell growth in the region of the brain associated both with memory and learning__."~~

~~#060:"And finally, CBD in particular is thought to limit the damage caused to the brain after a stroke by blocking the neurotransmitter, glutamate."~~

In summary:
~~#060:"This is one of the great advantages of cannabinoids. They have a very wide spectrum and are extremely varied compared to other neuroprotective agents that have been researched until now. These have consisted of anti-excitotoxins to improve the glutamate homeostasis, antioxidants or anti-inflammatories. But __what we know is that the various stimuli that cause cell death work together__. In other words, where there is excitotoxicity there is oxidative stress, the proteins become oxidized, they lose their function, they form together to make plaques, which causes an inflammatory response. __We are not going to halt neurodegenerative diseases unless we have neuroprotective strategies__ that work together by reducing inflammation while at the same time being antioxidants, inducing autophagy in order to eliminate the protein build up, and returning the glutamate levels to normal.__This is something that cannabinoids can do__, either one cannabinoid or a number of cannabinoids together"~~

In META-Health, we look mainly at the results of conflicts in terms of symptoms, while scientific research presented here observes the ways by which the results are created in the brain.and nervous system, and the ways cannabinoids influences those.
I think in our therapy releasing emotions, re-evaluating thoughts, and bringing the body and mind in a state of calm, we are using/targeting the very same system. Adding cannabinoids to the plan could help us get over blockages, and facilitate new orientation towards healthy interaction and self-development, thus making old triggers redundant.

In the brain, it might reduce both the impact of a UDIN and the oedema after a resolution, and by that also prevent the "calcifications" or placque being observed after recurring conflicts in one relay/area that we connect to the onset of dementia.
