Nope, but it's easy to do as long as you know what to do.
The easiest thing: add rare castes which can randomly tantrum. Just add
[CASTE:MALE_CRAZY]
[MALE]
[CASTE:FEMALE_CRAZY]
[FEMALE]
[MULTIPLE_LITTER_RARE]
[SELECT_CASTE:MALE_CRAZY]
[SELECT_ADDITIONAL_CASTE:FEMALE_CRAZY]
[CAN_DO_INTERACTION:CRAZY_FIT]
[CDI:ADV_NAME:Madness]
[CDI:USAGE_HINT:FLEEING]
[CDI:VERB:go crazy:has gone stark raving mad:NA]
[CDI:TARGET:A:SELF_ONLY]
[CDI:WAIT_PERIOD:10000]
[CDI:FREE_ACTION]
10000 here is time ticks between rages. Give those castes [POP_RATIO:X] where X is a small number in comparison to POP_RATIO on normal castes.
Don't forget to add an interaction itself.
[INTERACTION:CRAZY_FIT]
[I_SOURCE:CREATURE_ACTION]
[I_TARGET:A:CREATURE]
[IT_LOCATION:CONTEXT_CREATURE]
[IT_CANNOT_TARGET_IF_ALREADY_AFFECTED]
[I_EFFECT:ADD_SYNDROME]
[IE_TARGET:A]
[IE_IMMEDIATE]
[SYNDROME]
[SYN_NAME:madness]
[CE_FLASH_TILE:TILE:33:4:0:1:FREQUENCY:5:5:START:0:END:150]
[CE_ADD_TAG:CRAZED:START:0:END:150]
I typed from my head so I could make a few typos, but you get the idea.
CE_FLASH_TILE makes mad dwarves flash with a red "!" when they are in a crazy fit, and 150 on flash tile and CRAZED tag is the duration in tick the tantrum lasts.
You could make a mental medicine which adds a syndrome with [SYNDROME_CLASS:MENTAL] and lowers creativity/willpower (and maybe something else, like skills), and add [IT_CANNOT_HAVE_SYNDROME_CLASS:MENTAL] to the CRAZY_FIT interaction.
