Is it time to back NAC?

 

A lot of Parkinson’s research is focused on antioxidants – molecules that can reduce the level of stress a cell is under when it is not feeling well.

One of the most widely discussed antioxidants on Parkinson’s online forums is a molecule called Nacetylcysteine (or NAC).

Recently, the results of a small clinical trial – in which NAC was administered to people with Parkinson’s – have been published. The results are rather interesting.

In today’s post, we will discuss what NAC is, why it is important in the context of Parkinson’s, and we will look at what the new clinical trial report suggests about this molecule.

One question I get asked a lot is “What do you think of NAC?”

And I usually answer with my standard “I’m not a clinician, just an ex-research scientist. I can’t talk about medications or supplements, etc…”

But recently some interesting new data has been published regarding NAC and it’s kind of interesting.

What is NAC?

N-acetylcysteine (or NAC; also known as Acetylcysteine – commercially named Mucomyst) is a prodrug – that is a compound that undergoes a transformation when ingested by the body and then begins exhibiting pharmacological effects.

Acetylcysteine serves as a prodrug to a protein called L-cysteine, and – just as L-dopa is an intermediate in the production of dopamine – L-cysteine is an intermediate in the production of another protein called glutathione.

If you remember nothing else today, remember this: Acetylcysteine allows for increased production of glutathione.

And what is glutathione?

The TAU of Parkinson’s

Here at the SoPD, we regularly talk about the ‘bad boy’ of Parkinson’s disease – a protein called Alpha Synuclein.

Twenty years ago this year, genetic variations were identified in the alpha synuclein gene that increase one’s risk of developing Parkinson’s. In addition, alpha synuclein protein was found to be present in the Lewy bodies that are found in the brains of people with Parkinson’s. Subsequently, alpha synuclein has been widely considered to be the villain in this neurodegenerative condition and it has received a lot of attention from the Parkinson’s research community.

But it is not the only protein that may be playing a role in Parkinson’s.

Today’s post is all about TAU.

I recently informed my wife that I was thinking of converting to Taoism.

She met this declaration with more of a smile than a look of shock. And I was expecting the latter, as shifting from apatheism to any form of religious belief is a bit of a leap you will appreciate.

When asked to explain myself, I suggested to her that I wanted to explore the mindfulness of what was being proposed by Lao Tzu (the supposed author of the Tao Te Ching – the founding document of Taoism).

This answer also drew a smile from her (no doubt she was thinking that Simon has done a bit of homework to make himself sound like he knows what he was talking about).

But I am genuinely curious about Taoism.

Most religions teach a philosophy and dogma which in effect defines a person. Taoism – which dates from the 4th century BCE – flips this concept on its head. It starts by teaching a single idea: The Tao (or “the way”) is indefinable. And then it follows up by suggesting that each person should discover the Tao on their own terms. Given that most people would prefer more concrete definitions in their own lives, I can appreciate that a lot of folks won’t go in for this approach.

Personally speaking, I quite like the idea that the Tao is the only principle and everything else is a just manifestation of it.

According to Taoism, salvation comes from just one source: Following the Tao.

Oh and don’t worry, I’m not going to force any more philosophical mumbo jumbo on you – Taoism is just an idea I am exploring as part of a terribly clichéd middle-life crisis I’m working my way through (my wife’s actual response to all of this was “why can’t you just be normal and go buy a motor bike or something?”).

My reason for sharing this, however, is that this introduction provides a convenient segway to what we are actually going to talk about in this post.

You see, some Parkinson’s researchers are thinking that salvation from neurodegenerative conditions like Parkinson’s will come from just one source: Following the TAU.

What is TAU?
