- In Diane Bailey's post about aluminium and Alzheimer's diease, the
- argument seems to be (if I can follow it) :
-
- aluminium is dangerous
- aluminium does not need to be present in brain tissue to cause
- Alzheimer's
- aluminium can pass through the blood brain barrier and presumable leave
- again so therefore need not be present at the time of study
-
- But (and this is a significant but), where was the evidence that
- aluminium is at all involved in Alzheimer's disease without the
- findings of aluminium in the neural plaques? Was there any association
- before this finding?
-
- Aluminium is associated with a dialysis dementia that occurs when high
- amounts of aluminium are present in the dialysate. This should not occur
- now since it is a known complication and the preparations do check to
- ensure the levels are low.
-
- One of the significant conclusions that were drawn from the original
- studies (assuming that it was correct) was that since aluminium is not
- normally found in the brain - that aluminium is effectively stopped by
- the blood brain barrier from accumalating in large amounts; then the
- presence indicated a pathological process either is the ability to keep
- it out or acquisition by the neural tissue.
