        I'm not an expert on microbiology or Alzheimer's, but I remember
reading that Balin et al. found a bacterium called Chlamydia pneumoniae
(CPN) in the brains of 17 of 19 Alzheimer's patients, and in only 2 of 19
controls in 1998. Maybe a brain injury makes people more susceptible to CPN
infections.

        Are there any mechanisms whereby an injury would make a person more
susceptible to such an infection?
