I wouldn't be surprised if fresh epidemiological (whew, needed the spellchecker on that one...) studies found links to suicide, substance abuse etc, that were unknown simply because it wasn't tracked. Sidenote: testing for the infection is a routine blood test.

Or it could be a spurious correlation. If lots of folks in the general population are infected, then dementia patients and schizophrenics are bound to be among them. But it’s wise to rule it out as a cause.
