#delirium

• Ab hoc et ab hac - A Latin phrase literally translated as 'from this one and from that one' or 'about this and about that'. In clinical psychology, neurology, and psychiatry, it describes a chaotic, incoherent speech with no logical connection between ideas, typical of patients experiencing delirium episodes, dementia, acute mental confusion, or severe intoxication with psychoactive substances.
• abera - To deviate from normal mental, cognitive, or behavioral manifestations; to express delusional, incoherent, or clinically illogical ideas during a psychotic episode, acute febrile state, or delirium. In early semiology, the term described the wandering of the mind or the deviation of an organ from its natural anatomical function or trajectory.
