Which suffix denotes a state of frenzy or obsession?

The suffix that denotes a state of frenzy or obsession is -mania. In medical terminology, this suffix is often used to describe conditions characterized by excessive enthusiasm, obsession, or wild excitement. For instance, in the term "pyromania," it indicates an obsession with fire.

In contrast, the other suffixes serve different purposes: -pathy refers to a disease or disorder (as seen in "neuropathy"), -scopy denotes a procedure of examining or observing (like in "endoscopy"), and -desis indicates a binding or surgical fixation (used in terms such as "arthrodesis"). Each of these suffixes has distinct meanings relevant to various medical contexts, but only -mania specifically addresses the concept of a state of frenzy or obsession.
