I have a morbidly curious mind (I can’t help it, I was born this way). For instance, I’m fascinated by incredibly rare diseases and disorders. It’s part of what inspired me to write a book about mental illness. So I spent some time going down the bizarre rabbit hole of radical disorders for an article that just went live on author, David Bernstein’s website.

Example 1: The Cotard Delusion: a rare, though real, neuropsychiatric disorder in which patients believe that they have died, do not exist, are putrefying, or have lost their vital organs.

If this has piqued your interest, proceed to David’s site for more. Scroll past his acclaimed catalog of twisted horror titles to find the article below. Warning: hypochondriacs should avoid at all costs.
