Acupunctures neurological mechanisms

 

In a recent study into the neurological mechanisms of acupuncture the authors open saying,

‘Acupuncture treats nervous system diseases by increasing the brain-derived neurotrophic factor level and involves multiple signal pathways, including p38 MAPKs, Raf/MAPK/ERK 1/2, TLR4/ERK, PI3K/AKT, AC/cAMP/PKA, ASK1-JNK/p38, and downstream CREB, JNK, m-TOR, NF-κB, and Bcl-2/Bax balance. Acupuncture affects synaptic plasticity, causes an increase in neurotrophic factors, and results in neuroprotection, cell proliferation, antiapoptosis, antioxidant activity, anti-inflammation, and maintenance of the blood-brain barrier.’

Which is nice.

Probably doesn’t make a whole lot of sense to you though unless you have a degree in neurobiology. Perhaps some of the most important phrases in there are, well actually all of them, but particularly neuroprotection, anti-inflammation and maintenance of the blood-brain barrier. These three alone are some of the most important factors in neurological diseases including Alzheimer’s, dementia and Parkinson’s. Not only the scariest diseases around, but also, as of this year, the leading causes of death in the UK population. To summaries, acupuncture, through it’s neurological mechanisms, can help mitigate and prevent the leading cause of death in the UK.

What is also pretty interesting here, especially for an acupuncturist and a biology geek, is that there are so many pathways involved in its mechanisms of action, especially for such a simple procedure. Most medications are made to just target one pathway at a time, yet with the simple insertion of a few needles you can affect multiple pathways! Very cool.

Another four exciting phrases are synaptic plasticity, increased neurotrophic factors, anti-apoptosis and cell proliferation. Essentially these all chalk up to increased growth and repair in the brain and nervous system as a whole. Apoptosis is the process of cell death that can be caused by a wide variety of issues, whereas all of the others are to do with cell development or growth. Again, we see acupuncture working both sides of the equation in order to benefit the nervous system. These mechanisms are very useful for the reduction and prevention of the above mentioned diseases. They can also be useful for repair of the nervous system, for instance, after stroke. This is something that we don’t see acupuncture used for as regularly in the UK, but it is common place in China, there are even whole in-patient hospitals devoted to stroke rehabilitation through acupuncture, herbal medicine and physio.

Indeed, the study goes on to mention the benefits of acupuncture for stroke;

‘Acupuncture has shown beneficial effects on ischemic stroke rehabilitation by exerting the antiapoptosis effect on the ischemic area, promoting neurogenesis and cell proliferation, and regulating cerebral blood flow.’

Essentially, it helps the area of the brain affected by stroke to regrow and repair. It is also shown to reduce the recurrence of strokes. Again, stroke is a leading cause of death in the UK population.

I would recommend trying to read the referenced article as it also goes on to mention the biological mechanisms of why acupuncture is beneficial for seizures, haemorrhagic injury and depression.

As a practitioner it is great to see so many mechanisms being researched and discovered that corroborate the results we see in the clinic.

If you would like to chat to me about any of the above conditions please email or call me.
