Ailments in the Final Fantasy Zero game are negative status effects — things that characters must labor under, that they're often interested in removing as early as possible.
Each ailment has a level, which is the normal minimum level for being able to inflict that ailment, and a keyword that describes if it affects the creature mentally or bodily. It also has methods for removal (often using Saving Throws). Unless otherwise mentioned, the esuna spell and the Remedy item will remove the status as well. Being KO'd removes all ailments
It is possible to use certain ailments (such as Berserk) as part of a strategy to enhance your party, due to some of their positive side-effects. However, they are included in the "ailments" category due to the fact that some creatures may be immune to them — there are no creatures with immunity to enhancements.
Certain ailments are special: Instants are ailments that come and go before anyone can react, so they cannot be removed in the common ways (e.g.: a remedy only removes ailments currently affecting an individual). Permenants are ailments that will not end on their own, and, generally, will not be removed with a Safe Crystal, either. Until pro-active action is taken, the ailment will remain.
