Smoking and Alzheimer's

Column in question - Does smoking have any health benefits? 1995.

In light of the most recent review of all previous papers dealing with smoking and Alzheimer’s (Cataldo et al. 2010), it may be wise to update the column. This study found that non-tobacco industry affiliated papers indicated that smoking was a significant risk factor (averaging 1.72 ± 0.19 (P< 0.0005)) in developing Alzheimer’s. Mysteriously, affiliated papers (not always disclosed in the paper) yielded an odds ratio of 0.86 (95% CI, 0.75–0.98).
