Is it true that Friedrich Nietzsche suffered a mental collapse in 1889 and never recovered?

Yes. A reference biography states that in 1889 Nietzsche suffered a neurological collapse and a complete loss of mental faculties, living out his remaining 11 years until death. A peer-reviewed neurosurgical paper also confirms his 1889 mental collapse, though it does not address recovery.
