What are the signs?
The delusional disorder, if left untreated, might lead to depression, often as a consequence of difficulties associated with the delusions. Delusions also can lead to violence or legal issues; for instance, stalking or harassing the object of delusion, could lead to arrest.
8 Other persistent delusional disorders. Disorders in which the delusion or delusions are accompanied by persistent hallucinatory voices or by schizophrenic symptoms that do not justify a diagnosis of schizophrenia (F20.
A disorder characterized by the presence of one or more nonbizarre delusions that persist for at least 1 month; the delusion(s) are not due to schizophrenia or a mood disorder, and do not impair psychosocial functioning apart from the ramifications of the delusion(s).
Delusional Disorder DSM-5 297.1 (F22)
Delusional disorder is a type of mental health condition in which a person can't tell what's real from what's imagined. There are many types, including persecutory, jealous and grandiose types. It's treatable with psychotherapy and medication.
Persistent delusional disorder is diagnosed when a person exhibits non-bizzare delusions of at least 1 month's duration that cannot be attributed to other psychiatric disorders. Delusions are subdivided according to their content into various types.
Delusional disorder is distinguished from schizophrenia by the presence of delusions without any of the other symptoms of psychosis (for example, hallucinations, disorganized speech, or disorganized behavior).
Types of Delusions in Delusional DisordersErotomanic: The person believes someone is in love with them and might try to contact that person. ... Grandiose: This person has an over-inflated sense of worth, power, knowledge, or identity. ... Jealous: A person with this type believes their spouse or sexual partner is unfaithful.More items...•
The most frequent type is the persecutory delusion. This paranoid thinking can be severe—law enforcement is bugging the phone, for example. People with this type of delusion may suffer from illnesses such as schizophrenia, bipolar disorder, or dementia.
In the DSM-IV (Glossary) delusions were defined as follows: Delusion. A false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary.
There are several subtypes of delusional disorders and some of these include:Persecutory delusion. ... Delusion of grandeur. ... Delusional jealousy. ... Erotomania or delusion of love. ... Somatic delusional disorder. ... Induced delusional disorder or folie a' deux.More items...

Therefore, a hallucination includes seeing, hearing, tasting, smelling, or feeling something that isn't there. On the other hand, delusions are false beliefs despite evidence to the contrary.

Delusional disorder is one of the less common psychotic disorders, in which patients have delusions but not the other classical symptoms of schizophrenia (thought disorder, hallucinations, mood disturbance or flat affect). There have been some changes in diagnostic criteria for this condition in the new edition of the Diagnostic ...
Symptoms of Delusional Disorder. Delusions are generally categorized in 4 groups: bizarre, non-bizarre, mood-congruent and mood-neutral. Bizarre delusions are strange and implausible, such as being vivisected by aliens, while non-bizarre delusions are possible but unlikely, such as being under surveillance.
Patients with delusional disorder may be difficult to treat, in part because of the centrality of the delusions in their lives and in part because the delusions may not be very disruptive in the absence of other positive or negative psychotic symptoms. The often-formidable internal logic of the delusional system, even if wrong, may also militate against treatment adherence. Put another way, if you believed unhesitatingly that you were President of the United States, or that you were being poisoned, or that your wife had put you in treatment so she could run off with the postman, would you take your medication? A nonconfrontational culturally-sensitive approach to agreed-upon therapeutic goals, that includes the family when possible, is recommended, outpatient in nature except when violence or harm are concerns and aimed at maintaining social function and improving quality of life (Fochtmann, 2005).
DSM-5 changes the diagnostic criteria for delusional disorder to reflect revision of the diagnostic criteria for schizophrenia. In previous editions of the manual, delusions had to be “non-bizarre”, i.e., having erroneous beliefs related to real life (being followed or poisoned or persecuted) rather than, for example, the iconic delusion of being Napoleon Bonaparte. Bizarre delusions, such as detachment or liquefaction of body parts, can now be identified as manifestations of delusional disorder if they cannot be better explained by conditions such as body dysmorphic disorder or obsessive compulsive disorder. In addition, DSM-5 removes the distinction between delusional disorder and shared delusional disorder, in which two or more individuals share a delusional belief, historically referred to as folie à deux. It was previously difficult to diagnose delusional beliefs in more than one person if the belief in question might ordinarily be widely shared in the patients’ culture, such as demonic possession at certain times in history or the existence of elves in certain countries. The revised criteria simply propose that if two patients strongly espouse an erroneous belief and have the other symptoms described above, then both patients have delusional disorder.
Diagnosis of delusional disorder requires the presence of delusions of at least 1 month’s duration. The patient must never have met Criterion A for schizophrenia, which means that delusions must not have been accompanied by most types of hallucinations, disorganized speech (incoherence or derailments into tangents), grossly disorganized or catatonic behavior, or negative symptoms (flattening of affect, muteness, loss of volition). Tactile and olfactory hallucinations may be part of nonschizophrenic delusions, but not auditory or visual ones. Functioning must not be affected except for the immediate consequences of the delusions, such as hiding from imagined pursuers or preparing to confront the supposed lover of one’s wife. Episodes of mood disturbance if present must be much briefer in duration than the delusions: a patient who is despondent all the time because he is sometimes sure that he has cancer is more likely to be depressed than delusional. The delusion (s) must not be due to a general medical condition or to the effects of drug abuse or medication.
compared patients with delusional disorder to schizophrenics and age-matched normal controls (2002). Patients with delusional disorder had greater sensitivity to small doses of the dopamine-blocking neuroleptic haloperidol than did schizophrenic patients. Plasma levels of the dopamine metabolite homovanillic acid (HVA) were higher in patients with delusions of persecution than in controls, but not in patients with delusional jealousy, and elevated HVA levels decreased with haloperidol treatment. Certain polymorphisms or gene variants associated with the DR2 and DR3 dopamine receptors and the enzyme tyrosine hydroxylase involved in dopamine synthesis were significantly more common in delusional disorder than in schizophrenia or normal controls. These findings suggest that delusional symptoms arise from dopaminergic hyperactivity and may have a genetic basis.
Despite profound conviction about the delusion, the patient is often secretive or suspicious in discussing it. Delusional patients tend to be oversensitive and humorless, especially regarding the delusion. The belief is central to the patient’s existence, and questioning it elicits an inappropriately strong emotional reaction. The belief is nevertheless unlikely, and not in keeping with the patient’s social, cultural or religious background. The patient is highly invested emotionally in the belief, and other elements of the psyche may be overwhelmed. If the belief is acted upon, abnormal behavior may result which is out of character for the patient, but which may be understandable in light of the delusion; the belief and behavior are felt to be uncharacteristic by those who know the patient.
