Dr Gita Ramdharry, AHP consultant: “So some of the questions we get asked quite a lot in clinic is how many other people have my condition.
So I can tell you a little bit about some of the nerve conditions that we see.
So we either see people who have inherited nerve conditions with conditions like Charcot-Marie-Tooth disease (CMT), and we see people with inflammatory nerve conditions such as CIDP or Guillean-Barré syndrome.
Now, these are relatively rare conditions with CMT, the inherited neuropathy about 40 in a 100,000 people are affected by that, which works out about one in two and a half thousand. And the inflammatory neuropathies are much rarer. So between eight to ten in a hundred thousand people are affected by those muscle conditions.”
Dr Aisling Carr, Consultant Neurologist:
“So muscle conditions, if you group them all together, muscle diseases that are inherited are about nearly 40 per hundred thousand.
But we usually subdivide those up depending on what the gene causes.
And individually, things are much, much rarer.
The inflammatory myopathies, which are the treatable type, are rarer again.
They occur in about two per hundred thousand, but then Myasthenia Gravis, which again is a treatable disease which affects the connection between the nerve and the muscle, has a frequency of about 20 per 100,000.”
