This paper is based on a significant trend test between fish
consumption and incidence of dementia. A similar trend test between meat
consumption and incidence of dementia proved to be negative. It is,
however, worth checking out the results. Thus, incidence of dementia for
those who eat fish daily is 1% per year. This figure is based on 19
persons, one of whom had dementia. My point is that the study's thrust is
entirely based on this unique case. Had one counted two cases of dementia
instead of one, incidence would be about 2% per year, and the whole
incidence trend for people consuming fish would be no more significant
than in those consuming meat. Given the difficulty of diagnosis of
dementia and Alzheimer's disease, the possibility evoked here is highly
likely.

Shaky ground for fish
