The hallmark trait of delusional disorder is a strong belief in or about something that does not align with reality. The belief is either entirely untrue or it is an extreme exaggeration of the truth. Often, these beliefs are based on an ongoing misinterpretation of perceptions or experiences.
A principal components analysis indicated 4 components: distress, belief strength, obtrusiveness and concern. It is argued that delusions are most usefully regarded as multi-dimensional and, while characterised by conviction, vary considerably on other important dimensions.
Delusional disorder is a type of psychotic disorder. Its main symptom is the presence of one or more delusions. A delusion is an unshakable belief in something that's untrue. The belief isn't a part of the person's culture or subculture, and almost everyone else knows this belief to be false.

Delusions are common to several mental disorders and can be triggered by sleep disturbance and extreme stress, but they can also occur in physical conditions, including brain injury or tumor, drug addiction and alcoholism, and somatic illness.

It is best to talk to your loved one about your concern when they are not in the midst of their delusion. Stay neutral. Do not try and convince your loved one that their delusions are not real.
For example, you might feel that something or someone is trying to control, harm or kill you (even when you have no reason to believe this). These ideas are sometimes called paranoid delusions.
The main symptom is the presence of delusion. This type of delusion can influence a person's behavior. People with delusional disorders don't see their beliefs as irrational or inaccurate even when others point this out. So, they don't have a good sense of the problems created by their belief.
The mean age of onset is 40 years and ranges from 18-90 years. A Spanish study conducted by de Portugal et al looked at medical records of 370 people diagnosed with delusional disorder and found that the mean age in this population was 55 years, with 56.5% of the patients being female.
The diagnosis of delusional disorder is based on the DSM-5 diagnostic criteria, which include criterion A i.e the presence of one (or more) delusions with a duration of one month or longer, criterion B i.e criterion A for schizophrenia has never been met, criterion C i.e apart from the impact of the delusion(s) or its ...
The authors describe a scale designed to measure five dimensions of delusional experience: conviction, extension, bizarreness, disorganization, and pressure. Reliability was adequate to excellent on four of the dimensions, but only fair on the dimension of bizarreness.
The stages of delusion formation
Conard has proposed five stages in the development of delusional psychosis. Trema: Delusional mood representing a total change in perception of the world. Apophany: A search for, and the finding of, new meaning for psychological events. Anastrophy: Heightening of the psychosis.

They might make you feel like: A co-worker is trying to hurt you, like poisoning your food. Your spouse or partner is cheating on you.
More than half of the patients (64 percent) recovered from their long-standing delusions. These were people who had been begun the trial with persistent severe delusions, other troubling psychiatric symptoms, and very low psychological wellbeing — the toughest group to target with a new treatment.
Encourage a diagnosis and treatment; learn through your own therapy how to best support your loved one; avoid challenging delusions and acknowledge that they feel real to the person experiencing them; and above all, take care of yourself and your own mental and physical health.
Beginning in early adulthood, people with a paranoid personality disorder have a pervasive distrust and suspiciousness of others and their motives. Behavior is not obviously bizarre or odd. People with delusional disorder tend to function relatively well, except when their specific delusions cause problems.
While there are many types of delusions, delusions of grandeur are often associated with narcissistic personality disorder (NPD). These refer to believing you are superior and more deserving than other people.
Delusions are linked directly to psychosis, but not all delusions are that extreme. In fact, anxiety commonly causes delusional thinking, simply because of what it's like to deal with anxiety.
