In today’s post we will review recent research regarding one particular family of bacteria, Helicobacter pylori, and what they might be doing in relations to Parkinson’s disease.
In his magnificent book, I contain multitudes, science writer/journalist Ed Yong writes that we – every single one of us – release approximately 37 million bacteria per hour. By talking, breathing, touching, or simply being present in the world, we are losing and also picking up the little passengers everywhere we go.
Reminds me of that Pascal Mercier book “Night Train to Lisbon” – We leave something of ourselves behind when we leave a place,… I’m not sure if this is what he was referring to though.
Yong also points out that: 80% of the bacteria on your right thumb are different to the bacteria on your left thumb.
It’s a fascinating book (and no, I am not receiving any royalties for saying that).

We have discussed microbes several times on this blog, particularly in the context of the gut and its connection to Parkinson’s disease (Click here, here and here to read some of those posts). Today we are going to re-visit one particular type of microbe that we have also discussed in a previous post: Helicobacter pylori.

For many people diagnosed with Parkinson’s disease, one of the scariest prospects of the condition that they face is the possibility of developing dyskinesias.
Dyskinesias are involuntary movements that can develop after long term use of the primary treatment of Parkinson’s disease: Levodopa
In todays post I discuss one experimental strategy for dealing with this debilitating aspect of Parkinson’s disease.

There is a normal course of events with Parkinson’s disease (and yes, I am grossly generalising here).
First comes the shock of the diagnosis.
This is generally followed by the roller coaster of various emotions (including disbelief, sadness, anger, denial).
Then comes the period during which one will try to familiarise oneself with the condition (reading books, searching online, joining Facebook groups), and this usually leads to awareness of some of the realities of the condition.
One of those realities (especially for people with early onset Parkinson’s disease) are dyskinesias.
What are dyskinesias?
Dyskinesias (from Greek: dys – abnormal; and kinēsis – motion, movement) are simply a category of movement disorders that are characterised by involuntary muscle movements. And they are certainly not specific to Parkinson’s disease.
As I have suggested in the summary at the top, they are associated in Parkinson’s disease with long-term use of Levodopa (also known as Sinemet or Madopar).
