Temporal-Mental Displacement

An early treatment for effontia was that of Temporal-Mental Displacement. Researchers discovered that the effects of Effontia couldn't be directly controlled, and could not find any way to cure the patient. Efforts to comfort the patient and family helped, but only filled physical comforts. They did little to help the minds of either the afflicted or their loved ones.
A new technique was attempted in 756 noted that while the patient was unable to be present in the present and often believed themselves to be in the past. The world disagreed, and the researchers theorized that that disagreement between the patient's mind and the rest of the world led to many of the magical side-effects.
Rather than attempting to fix the patient's mind so it was tethered appropriately in the present, the suggestion was instead to try to tether the minds of the caregivers and loved ones with that of the patient themself. It would allow them the opportunity to spend more time together in an environment that all could percieve and understand.
While this did little to help the patient themselves, it helped the loved ones immensely. While they may not be recognized as themselves in the world of the patient's mind, they could still interact with and be close. This had additional benefits that the loved ones' beliefs helped solidify the structure of the patient's mind, grounding them in a world of their making but with the rules and structure that normally exist. This cut down greatly on the number of magical effects that leaked into the real world.
While the world such patients created was almost always a world of their past, they never (as far as researchers could find) actually were in their own past. None of the Temporal-Mental Displacement therapy led to any actual recorded time-travel or temporal paradox type effects one would expect were actual time trave involved.
