[edit] older talk
It should be reversed.
Is there any real need to have two separate articles for Progressive supranuclear palsy and Supranuclear palsy? --Bicycle repairman 17:11, 24 January 2006 (UTC)
I've merged them. JFW | T@lk 17:16, 24 January 2006 (UTC)
[edit] Rare?
A rare disease with over 10,000 sufferersin the UK alone? Rich Farmbrough 08:58 18 May 2006 (UTC).
[edit] Re:Rare?
Considering the United Kingdom has around 60 million inhabitants, that makes 1 sufferer for 6000 inhabitants. From: http://en.wikipedia.org/wiki/Rare_disease:
" A rare disease has such a low prevalence in a population that a doctor in a busy general practice would not expect to see more than one case a year. (...).
As a guide, low prevalence is taken as prevalence of less than 5 per 10,000 in the community [1].
The NIH's Office of Rare Diseases states that, "an orphan or rare disease is generally considered to have a prevalence of fewer than 200,000 affected individuals in the United States" "
Now let's see the "low prevalence": less than 5 sufferers per 10,000 inhabitants.
To reach the number of affected by PSP (which is 10,000), we have to multiply 5 per 2000:
(5 * 2000 = 10,000). And to reach the -in theory- total number of inhabitants, we do the same (10,000 * 2000 = 20,000,000).
So, in theory, there should be ten thousand sufferers for every twenty million inhabitants. As I've stated before, the United Kingdom has about sixty millions inhabitants. So, the ciphers are OK, and yeah, we can consider PSP "A rare disease with over 10,000 sufferersin the UK alone"... Which is the point I tried to prove!
