Symptoms Of Delusional Disorder

Delusional Disorder

Like schizophrenia, delusional disorder is characterized by the presence of delusions that persist for at least one month, and which often involve prominent psychotic themes: erotomanic, grandiose, jealous, persecutory, and/or somatic. Unlike schizophrenia, however, hallucinations are not prominent, unless related to the delusions. Delusional disorder also tends to start later in life than schizophrenia, and tends to leave patients' psychosocial functioning (their ability to care for themselves, work, have relationships, etc.) relatively unimpaired (See the section above covering delusional types for more detail).

The following diagnostic criteria must be met before a diagnosis of Delusional Disorder is warranted, according to the DSM-IV-TR:

A) Non bizarre delusions (i.e., involving situations that occur in real life, such as being followed, poisoned, infected, loved at a distance, or deceived by spouse or lover, or having a disease) of at least 1 month's duration.

B) Criterion A for Schizophrenia has never been met.

C) Apart from the impact of the delusion(s) or its ramifications, functioning is not markedly impaired and behavior is not obviously odd or bizarre

D) If mood episodes have occurred concurrently with delusions, their total duration has been brief relative to the duration of the delusional periods

E) The disturbance is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition

    I have a friend that is a compulsive lyer, he has destroyed my life by dognapping my companion of 61/2 years, Gizmo, my little pekingnese, he has my cell phone and refusses to give it back to me , so I have had to have the sevies turned off and have another one ordered to be sent to my home, previos to this I had just had my home phone and cell number changed to keep him from calling me, but after my baby was stollen , I put a n add in the paper with both numbers so he was able to get them in the paper. He vandleized my daughters grave by taking several large flower pots of dirt that I had once had and left in his back yard and dump them on top of her grave and headstone, He says that he didn't do it but who else would have taken them out of his yard an known where my daughters grave plot was to dumo them on top om it. He is saying that I fabercated the story because the cemetary groundsman cleaned it up for me the next day after I reported it to the office of the cemetary and nobody else so it. I told him that I would get a written statement from the cemetary, then I thought I didn't Have to prove anything to hem, He knw that He did it. He has stolen two diferant watches that I have forgotten at his house and all he will tell me is that he will look for them when he gets tiem, I know where I left them and they're aren't there now. He has intentionally broken some of my glass bells when he has been upset at me fow nothing, like if I was late getiing back from somewhere or I didn't do something the way that he wanted me to do it. The list goes on an on What type of perso is this?? I have gotten out of this relationship, but he keeps trying to pull me back in. I still miss my little dog and I know that he had something to so with his disaperance.

    Sincerely,Deborah Gibson
