Post-Ringbearer Syndrome

Post-Ringbearer Syndrome is a condition suffered by the immortal and 6000-year-old Frodo Baggins in the well-known goodfic Bagenders. As it is described in the first chapter of said fic:

"Bearing a ring of ultimate evil takes its toll on the mind, as does 6000 years of blatantly misguided psychiatric care. The 'episodes' varied in frequency and severity, from mild gibbering which passed quickly to full on Sauron hallucinations and mental hospital admissions. Anti-psychotic drugs have little effect on the aftermath of the power of a dark lord."

It is unknown whether or not the compulsive desire to bake that he also suffers from is part of this syndrome.
