Treating paranoia is a process difficult because the affected person does not feel sick. She is in denial and is suspicious of everyone, including the doctor.

The neuroleptiques are sometimes prescribed when paranoia leads to delirium, but these drugs do not address the root of the problem, which is the abnormal way of thinking.

La psychotherapy can only be effective if the affected person agrees to be accompanied in this way, which is rarely the case.

THEhospitalization may be necessary, sometimes under duress, because a paranoid person can in some cases be aggressive and dangerous towards himself (suicide) or others (sometimes very serious physical aggression).
