Mental Disorders

Ocean Absence Syndrome
Ocean Absence Syndrome, or OAS, is developed only in water elementals when they're kept away from the ocean too long. This can drive them to self-harm or suicide if kept locked away long enough.

Grooming Syndrome
Grooming Syndrome occurs more commonly in female Bellurium and Dairfinxs (though it does happen in others), causing the nearly uncontrollable urge to groom one's fur. Sometimes this may be with a brush, paws, or even the Elemental's own tongue, but that last one is rather rare. When it does happen, an Elemental may throw up fur-balls, or if they don't, they may require surgery to extract the fur. More extreme sides of Grooming Syndrome could cause death if left untreated.

Mental Shut Down
Sort of like an Emotional Shut-Down, but where certain parts of an Elemental's brain just stop working. There are varying degrees to this, but if it gets bad enough, an Elemental could simply revert back to their feral instincts with no way to get them back. They may lose the ability to speak normally (or at all), the ability to shift easily (or, again, at all) and their sense of empathy, depending on their element. Fire Elementals who Shut-Down tend to cannibalize.

Abanism
Abanism is kind of like the Zanzus equivalent of Autism. It, like Autism, is a spectrum of symptoms and effects, but the most common effects are; refusing/trouble learning to speak as an Elet (IE. Communicating with noises only, perhaps even as an adult), showing intense primal fears (these often develop into anxiety, fear of their opposing Element, such as Plant Elementals to Fire to the point where the mention of fire sends them into a frenzy, etc.), discomfort with eye contact (Most common in Fire Elementals, it was definitely a challenge for them then), among other things.

Feral Thinking Disorder
Feral Thinking Disorder, or FTD, is an uncommon, genetic condition that occurs when the parts of the Anthro Brain that control critical thinking and decision making are overpowered by the Feral part of the brain that do the same things. This can be because the Anthro part is weaker than usual, or because the Feral part is stronger than usual, but the outcome is typically the same depending on the Element. Their motor functions aren't typically affected, but they may occasionally struggle with walking in their Anthro forms when angered/frightened (depending on the Element).

For most Elements, the effect is more just making decisions quickly and not being very good at brain games, but for fire Elementals, it's a very harmful thing, especially if they get angry easily already. For Plant Elementals, they get incredibly jumpy and skittish, constantly apologizing and being submissive to larger Elementals, even if they've done nothing wrong.
