Essential Oils and Alzheimer's
Are Essential Oils Useful in Treating Alzheimer’s Disease?
The human brain is a complex network of nerve fibers in which individual nerve cells communicate with each other by way of chemical messenger molecules called neurotransmitters. This transmission of nerve impulses is involved in all of the brain’s cognitive functions, including learning, memory, speech, and emotions. In Alzheimer’s disease (AD), damage to the neurofibral network from formation and accumulation of protein fragments called amyloids leads to death of nerve cells, and deterioration of cognitive abilities. Once the nerve cells have died, it is very difficult, if not impossible, to regenerate them. Thus, at least for now, AD is considered incurable. In the meantime, there is considerable interest in treatments that may prevent the disease or help ease the symptoms of the disorder. There has been an increasing amount of research that indicates essential oils (EOs) may be of use in this regard.
So, what might EOs do to help?
There are three ways, all three believed to be involved in the processes leading to AD.
The research described above, as well as much work not mentioned, strongly suggest that EOs may provide an excellent alternative, natural, widely available, and inexpensive treatment for AD, particularly for easing the symptoms of the disease. As noted in previous posts, this doesn’t mean that a particular EO will work for everyone. The work to date does suggest that there needs to be long-term, large, controlled clinical studies to determine the efficacy of such treatments, and validate their usage for the larger health community.
In the meantime, there would seem to be no downside to their use in individual cases. Coriander can spice up most any dish very nicely, and might provide some neuroprotection. Lavender oil can freshen the air and reduce anxiety. And there are no side effects!
At the very least, the idea of improving cognitive function with natural essential oils is pretty exciting. Questions? Leave a comment! And for general guidelines about essential oils, see our FAQ page.
