title: What was the cause of Nietzsche's dementia?
abstract: Many scholars have argued that Nietzsche's dementia was caused by syphilis. A careful review of the evidence suggests that this consensus is probably incorrect. The syphilis hypothesis is not compatible with most of the evidence available. Other hypotheses--such as slowly growing right-sided retro-orbital meningioma--provide a more plausible fit to the evidence.
