Professionals should carry out their tasks and assignments without bringing too much of emotion into it. Diagnoses should be taken into account, rather than trying to make it a routine, instead of patient-oriented.
An example of three patients suffering from different, but quite symptomatically similar dementia that are sometimes termed or tagged "aggressive". Aggression, breeds counter aggression. There I see this said aggressive nature as a special method of communication.
It could be that the attitudes of the professionals in question, seem to, either be untrusted, not understood, strange and even unfriendly in nature. So because one staff may have documented a patient to be aggressive, makes and put such patient on a "red" list. Thereby making it look like preparing for a battle when preparing to attend to such patient.
It is but quite interesting to know that, these patients react very differently to some other staff - a very calm and friendly manner. The act of caring seen as an art, science, even as a particular technique. It should not be taken or perceived as a one way route, but rather individualised, in essence, patient-centred-care.
The biography of patients should not be underestimated, but put to use as a tool or road map to achieving a goal. By doing this, it make caring, nursing and therapy, as the case may be, interesting, rather than otherwise.
