Articles like these are abundant, it is clear that this issue is not resolved and that the Prion theory is not proven so Venetia where do you get off by claiming that Prions ARE (as you so emphasized in caps) the cause of Alzheimer's?
Quote:
| But the theory is incomplete. It doesn't explain exactly how the misshapen proteins trigger the avalanche, or why the disease can take so long (sometimes decades) to appear. Even his supporters were surprised this year when Professor Prusiner received the Nobel Prize for Medicine; Nobels are usually awarded for work which has proved itself fully. |
Prion theory which defied the CJD orthodoxy - News - The Independent Quote:
| Not all researchers are sold on the prion theory; many believe that a more traditional pathogen like a virus will yet be isolated. Last week this camp got a boost when the journal Science published a study in which a group of lab mice injected with BSE-infected tissue all came down with the disease, yet fewer than half were shown to harbor Prusiner's infectious prions. Opponents of the prion theory say this proves the proteins don't cause disease. Proponents insist that the methods used to detect the molecules were simply not sensitive enough.
