Delusional disorder, fully known as paranoid disorder, was a serious mental illness in which patients persistently held strong beliefs that did not align with reality, and those beliefs were usually difficult to change through evidence or rational persuasion.
The causes of delusional disorder were complex, involving psychological and biological factors. High-risk groups included people with a family history, those who had suffered major psychological trauma, or those who had long been under intense pressure.
Its primary clinical symptoms included persistent, illogical delusions, such as firmly believing that one was being followed, framed, or secretly loved by others.
Patients might consequently suffer from anxiety, fear, abnormal behavior, and social difficulties. It was worth noting that delusional disorder was not contagious. It was a mental illness caused by internal factors and could not be transmitted through contact, air, food, or other means.
Delusional disorder did not directly cause death, but the suicidal behavior and accompanying mental health issues it could trigger might indirectly endanger a person's life.
To wizards, such mental illnesses were all "fragile ailments" that Muggles were prone to. Pure-blood Wizards even attributed mental illness to impure bloodlines, considering it a sign of "degeneracy."
Fudge was not as extreme as they were, but he still shifted his chair back slightly.
Umbridge, who was still denouncing the Batman Family's "crimes," seemed not to notice his movement. She rattled off a hundred reasons Batman had to die. Naturally, his cause of death would be a Dementor's Kiss, preferably under her personal supervision.
As Fudge listened, his thoughts had already drifted far away.
Whether Umbridge had delusional disorder or not, she would not be able to return to Hogwarts anytime soon to continue their plans.
As for the other Special Educational Commissioners, honestly, Fudge did not believe they could replace her.
"I know!"
