Review
We present a case study of a patient who was hospitalized with the initial diagnosis of psychotic depression with predominant delusions of poverty. During his hospital stay despite antidepressant and antipsychotic treatment with 150 mg of sertraline and 20 mg of olanzapine per day, no symptomatic improvement was achieved. Besides, the psychotic features have risen to the fore along with inadequately vaguely expressed affective component. What drew attention was the coherence and permanence of delusional judgements, which, albeit variable in expression, always concerned one theme - the belief of an inevitable bankruptcy. The whole clinical picture, both with the objectifying interview defining the order of emerging symptoms, was suggestive and the verification of diagnosis was made. Persistent delusional disorder with delusions of poverty with subsequent mood disorder was diagnosed. The treatment with 275 mg of clozapine per day was started and we observed a slow gradual withdrawal of psychosis as well as a total normalization of the affective range. The case illustrates the importance of differential diagnosis of mental states in which psychotic features coexist with affective symptoms. It is helpful to determine the sequence of the symptoms development. It should be noted that although the ICD-10 classification distinguishes exclusively 7 subtypes of persistent delusional disorder, in the clinical practice we can encounter other thematic areas of psychosis. It brings substantial therapeutic and prognostic implications.

Review
The theme, strength, and duration of a delusion are considered important in distinguishing one psychosis of old age from another. Research results, however, are mostly based on studies conducted on one form of psychosis, namely schizophrenia. The aim of this hypothesis-driven narrative review is to gather clinically important information about the psychosis identified as delusional disorder (DD), as it affects persons of senior age. We hypothesized that DD becomes relatively prevalent in old age, especially in women; and that it is associated with demonstrable brain changes, which, in turn, are associated with cognitive defects and poor pharmacological response, thus increasing the risk of aggression and suicide. Computerized searches in PubMed and ClinicalTrials.gov were conducted using the following search terms: (delusional disorder) AND (elderly OR old OR aged OR psychogeriatrics). A total of 16 recent studies (including case reports) were reviewed. Our hypotheses could not be definitively confirmed because research evidence is lacking. In order to improve eventual outcomes, our literature search demonstrates the need for more targeted, well-designed studies.

Review
The de Clérambault syndrome, commonly known as erotomania, is a delusional disorder in which the patient is convinced that another person has fallen in love with him or her. The syndrome is more frequent in female patients, who usually believe that their lover is a man belonging to a higher social and economic class, or is married, unknown, or even imaginary or deceased person. The course of the syndrome is usually chronic, with serious problematic behavioural consequences, including stalking behaviours, such as repetitive calling, unexpected visits or continuous attempts to send gifts or letters. According to the DSM-5, this syndrome is included in the erotomanic type of the delusional disorder, however, it is usually neglected in psychiatric practice and almost forgotten by modern psychiatrists.

Review
In his textbook from 1838, Esquirol made the first comprehensive psychopathological description of paranoia, which he labeled partial psychosis. This was a condition with encapsulated, well organized, and persistent delusions. These are defended with a great deal of emotions and sharp argument. The individual appears quite convincing, especially because he or she otherwise behaves rationally. The intellectual capacity is used to achieve defined goals according to the delusional content. This condition is difficult to uncover because of dissimulation and adaptation. The frequency in the population is unknown, but the condition is rare in psychiatric treatment facilities, and usually only when the persons become litigious or criminal. In Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, the condition is covered by the concept of delusional disorder, but that concept also comprises benign acute/subacute conditions as well as cases that turn out to have the diagnosis changed to schizophrenia.

Review
BACKGROUND
Delusional disorder is commonly considered to be difficult to treat. Antipsychotic medications are frequently used and there is growing interest in a potential role for psychological therapies such as cognitive behavioural therapy (CBT) in the treatment of delusional disorder.
OBJECTIVES
To evaluate the effectiveness of medication (antipsychotic medication, antidepressants, mood stabilisers) and psychotherapy, in comparison with placebo in delusional disorder.
SEARCH METHODS
We searched the Cochrane Schizophrenia Group's Trials Register (28 February 2012).
SELECTION CRITERIA
Relevant randomised controlled trials (RCTs) investigating treatments in delusional disorder.
DATA COLLECTION AND ANALYSIS
All review authors extracted data independently for the one eligible trial. For dichotomous data we calculated risk ratios (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis with a fixed-effect model. Where possible, we calculated illustrative comparative risks for primary outcomes. For continuous data, we calculated mean differences (MD), again with a fixed-effect model. We assessed the risk of bias of the included study and used the GRADE approach to rate the quality of the evidence.
MAIN RESULTS
Only one randomised trial met our inclusion criteria, despite our initial search yielding 141 citations. This was a small study, with 17 people completing a trial comparing CBT to an attention placebo (supportive psychotherapy) for people with delusional disorder. Most participants were already taking medication and this was continued during the trial. We were not able to include any randomised trials on medications of any type due to poor data reporting, which left us with no usable data for these trials. For the included study, usable data were limited, risk of bias varied and the numbers involved were small, making interpretation of data difficult. In particular there were no data on outcomes such as global state and behaviour, nor any information on possible adverse effects.A positive effect for CBT was found for social self esteem using the Social Self-Esteem Inventory (1 RCT, n = 17, MD 30.5, CI 7.51 to 53.49, very low quality evidence), however this is only a measure of self worth in social situations and may thus not be well correlated to social function. More people left the study early if they were in the supportive psychotherapy group with 6/12 leaving early compared to 1/6 from the CBT group, but the difference was not significant (1 RCT, n = 17, RR 0.17, CI 0.02 to 1.18, moderate quality evidence). For mental state outcomes the results were skewed making interpretation difficult, especially given the small sample.
AUTHORS' CONCLUSIONS
Despite international recognition of this disorder in psychiatric classification systems such as ICD-10 and DSM-5, there is a paucity of high quality randomised trials on delusional disorder. There is currently insufficient evidence to make evidence-based recommendations for treatments of any type for people with delusional disorder. The limited evidence that we found is not generalisable to the population of people with delusional disorder. Until further evidence is found, it seems reasonable to offer treatments which have efficacy in other psychotic disorders. Further research is needed in this area and could be enhanced in two ways: firstly, by conducting randomised trials specifically for people with delusional disorder and, secondly, by high quality reporting of results for people with delusional disorder who are often recruited into larger studies for people with a variety of psychoses.

The aim of the present study is to investigate the relationship between personality, trait affectivity, and severity of delusions in patients with delusional disorder (DD). Thirty-two outpatients affected by DD were administered the Structured Interview for DSM-IV-TR Personality Disorders (SIDP-IV), the Pathological Narcissism Inventory (PNI), the Positive and Negative Affect Schedule (PANAS), and the Psychotic Symptom Rating Scale (PSYRATS). We analyzed the prevalence of personality disorder in our sample of patients with DD and studied the correlations between the severity of delusions and the different affective variables. Finally, we obtained a multivariate explanatory model of the severity of the delusions. The severity of delusions was directly associated with "grandiose fantasy" item of narcissistic personality and inversely related with the feelings of shame, fear, and guilt. In the multivariate model, the feeling of shame was the only independent variable capable of accounting for the severity of delusions that, in DD patients, would lie on an affective core of shame.

Delusional disorder is a relatively rare psychotic illness characterized by delusions with contents that are theoretically possible but highly unlikely, and an absence of the disorganized thought and negative symptoms characteristic of schizophrenia. The illness is rarely studied systematically and most guidance with regard to the treatment derives from case reports and small case series. Antipsychotic medications are the mainstay of treatment, but it is not clear whether any particular agent is more effective than others. We report the case of a patient with delusional disorder who had failed to respond to risperidone but improved markedly with aripiprazole. Aripiprazole may show promise as a treatment for delusional disorder, possibly as a result of its effects on both dopaminergic and serotonergic receptors.
