Introduction: Post-operative delirium remains a significant problem, particularly in the older surgical patient. Previous evidence suggests that the provision of supplementary visual feedback about ones environment via the use of a mirror may positively impact on mental status and attention (core delirium diagnostic domains). We aimed to explore whether use of an evidence-based mirrors intervention could be effective in reducing delirium and improving post-operative outcomes such as factual memory encoding of the Intensive Care Unit (ICU) environment in older cardiac surgical patients...

BACKGROUND: Childhood trauma has been associated with a more severe clinical expression of bipolar disorder (BD). However, the results that specifically associated traumatic events and psychotic features in BD have been inconsistent, possibly due to the low resolution of the phenotypes being used. METHODS: 270 normothymic patients with BD completed the Childhood Trauma Questionnaire (CTQ) and the Peters Delusion Inventory (PDI) that assessed 21 delusional beliefs...

Few reports exist about the treatment of body dysmorphic disorder (BDD) in patients who are suicidal. This case report describes a 19-year-old male with BDD who had delusional-intensity beliefs about facial disfigurement that had gradually intensified over a 2-year period. However, he was initially misdiagnosed with depression partly because he was admitted immediately after a suicide attempt that was associated with depressive symptoms and social withdrawal, symptoms that subsequently proved to be secondary to his BDD...

BACKGROUND: Despite the prevalence of mental health problems during the perinatal period, little research has examined psychotic symptoms in a community sample across pregnancy and the postpartum. Exposure to environmental risk factors, and immigration in particular, are associated with increased risk for psychotic disorders. The current investigation examined whether psychosocial risk and immigrant status would predict levels of delusional ideation across the perinatal period when controlling for depression, anxiety, and demographic factors...

Individuals with obsessive-compulsive features frequently visit dermatologists for complaints of the skin, hair, or nails, and often progress towards a chronic relapsing course due to the challenge associated with accurate diagnosis and management of their psychiatric symptoms. The current DSM-5 formally recognizes body dysmorphic disorder, trichotillomania, neurotic excoriation, and body focused repetitive behavior disorder as psychodermatological disorders belonging to the category of Obsessive Compulsive and Related Disorders...

The world will be facing huge population aged 65 and older, accounting for 13% of the total population in the future. Significant disabilities rates reflect an accumulation of health risks. Psychiatry disability is one of the most significant disabilities, because it manifests in cognitive, affective, and behavior disorders that limit one's daily life and restrict their participations. Very few studies have explored the 20 years associations between demographic factors and psychiatry disability among older people in China...

Research in western nations has found that pathologically fixated individuals pose a risk of serious harm to public figures, and that many of these fixated persons are mentally ill and require treatment. Over the past decade, integrated fixated threat assessment agencies have been established in western Europe and Australia to specifically assess and manage this group. The current study examines 400 consecutive referrals to a fixated threat assessment center in Queensland, Australia, with a particular focus on the mental health and risk profile of those who engage in inappropriate contact with public office holders...

AIM: Retrospective studies of first-episode psychosis patients have reported that psychosis often remains untreated for some time. Yet, from clinical samples, the characteristics and number of non-diagnosed untreated psychosis patients in a community can only be estimated. Thus, this short report compares socio-demographic and clinical features of diagnosed and non-diagnosed psychotic individuals assessed in the community. METHODS: Using telephone interviews, we clinically assessed 2682 community participants (aged 16-40 years) in the Canton of Bern, Switzerland, to examine the characteristics of non-diagnosed psychosis...

In some instances the ostensibly false narratives produced by patients with delusional misidentification syndromes (DMS) or confabulation may - unbeknownst to the patient - contain some authentic self-referential information. In this review, extracted from a video library or verbatim transcripts of approximately 50 clinical cases with either delusional misidentification or some variety of confabulation, we identified four cases (Feinberg, 2001, 2009, 2010; Feinberg & Shapiro, 1989) with either DMS for persons or confabulations about "phantom" persons, who showed prominent "self-referential" (SR) narratives...

BACKGROUND AND OBJECTIVES: Cognitive biases play a role in the development and maintenance of delusions. However, delusions are multidimensional (i.e., emotional and cognitive facets) and often co-occur with auditory hallucinations. Therefore, further refinement of the precise relationship between cognitive biases, delusions, and hallucinatory experiences is warranted. METHODS: A total sample of 167 patients with schizophrenia spectrum disorders was split into two groups consisting of patients with active delusions (n = 127) and active hallucinations (n = 92)...

BACKGROUND: Delusional disorder (DD) is an under-researched condition and its relationship to schizophrenia (SZ) controversial. This study aimed to further characterize DD and to examine multi-domain evidence for the distinction between DD and SZ. METHOD: Using univariate analyses we examined 146 subjects with DD, 114 subjects with paranoid SZ and 244 subjects with non-paranoid SZ on 52 characteristics from several domains including demographics, risk factors, premorbid features, illness characteristics, index episode features, delusional-related features, response to treatment and outcome...

BACKGROUND: Recent findings suggest that dopaminergic abnormalities found in psychotic disorders may be secondary to nitric oxide dysfunctions. Nitric oxide seems to influence glutamatergic and dopaminergic neurotransmission, both of which have been associated with psychosis. OBJECTIVE: To search and review published works which examined the influence of nitric oxide in psychotic disorders subjects. METHOD: The research was executed in the on-line collections of Pubmed and ISI Web of Science...

The majority of women suffering from psychiatric disorders in pregnancy and the breast feeding prefer psychotherapy and other nonpharmacological treatment over psychopharmacological treatment although the risk of malformations and postnatal complications in children exposed to psychopharmacological drugs must be regarded as acceptable in moderate to severely ill patients. Data are lacking, but several psychotherapeutic and biological treatments as well as noninvasive brain stimulation procedures have been investigated to treat depressive episodes and anxiety disorders in pregnancy and the breast feeding...

Delusions as a feature of psychosis have long captured the fascination of both psychiatry and the public at large. The French first described three famous delusions: the Cotard delusion, folie à deux, and Capgras delusion. In this article, we examine a case illustrating each delusion and the hallmark features of each as well as a brief discussion about the current understanding of these disorders.

The author analyze conceptions of mental signs of predisposition (diathesis, vulnerability) to non-psychotic and delusional mental disorders of functional origin described in the works of leading French psychiatrists of the late 19th/early 20th centuries (E. Regis, P. Serieux, J. Capgras, E. Dupre, J. Levy-Valensi etc). The descriptions of characteristics of some constitutional types and the differences in the structure of constitutional types and the structure of delusional disorders developed on their basis are compared...

BACKGROUND: First rank symptoms (FRS) of schizophrenia have been used for decades for diagnostic purposes. In the new version of the DSM-5, the American Psychiatric Association (APA) has abolished any further reference to FRS of schizophrenia and treats them like any other "criterion A" symptom (e.g. any kind of hallucination or delusion) with regard to their diagnostic implication. The ICD-10 is currently under revision and may follow suit. In this review, we discuss central points of criticism that are directed against the continuous use of first rank symptoms (FRS) to diagnose schizophrenia...

BACKGROUND AND OBJECTIVES: Delusions are usually anchored in past events associated with abnormal experiences or delusional interpretations of personal events. The characteristics of the memory of these experiences may contribute to maintain delusional beliefs by providing confirmatory evidence for the delusions. However, these aspects have not been investigated properly. METHOD: Seventeen patients with schizophrenia were examined in study 1 during a face-to-face interview...
