BACKGROUND: The delusional misidentification syndromes (DMS) include a myriad of discrete but related syndromes, which have wide spectrum anomalies of familiarity. Several misidentification syndromes have been described in the psychiatric literature, the most common of these delusions are: the Capgras syndrome; the Fregoli syndrome; the syndrome of inter-metamorphosis; reduplicative paramnesia; and environmental reduplication. CASE PRESENTATION: The reported case highlights the emergence of late onset first episode psychosis in a Middle Eastern 65-year-old female who has no previous psychiatric history...

Psychiatry and society are interrelated and the biopsychosocial model continues to dominate the clinical psychiatric practice. Some doubts have been expressed in recent years about the value and the wide acceptance of the biopsychosocial model. Ghaemi (2009)1 considers it to be anti-humanistic and advocates the use of less eclectic, less generic, and less vague alternatives. The fundamental changes that have been witnessed in our times across the spectrum of biology, psychology and sociology have made necessary that a conceptual clarity should prevail...

BACKGROUND: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a potentially lethal autoimmune disease. Early diagnosis and immunotherapy can improve prognosis; however, early prominent psychiatric symptoms have led to misdiagnosis in numerous cases, delaying diagnosis and treatment. This study aimed to explore the clinical features and psychiatric symptoms of anti-NMDAR encephalitis and the association between antibody titers and psychiatric symptoms. METHODS: In this retrospective study, 43 patients with anti-NMDAR encephalitis and 70 new-onset psychiatric patients were enrolled...

This is the first case report in a country predominated by Chinese that describes the physical abuse of a recipient by the inducer in shared delusional disorder. The report describes a 42-year-old patient who physically abused her father until he submitted to her delusions. Subsequently and for years, both sustained persecutory delusions against their neighbours. While the patient was undergoing treatment, the father continued reinforcing her delusions. There is a need to explore the possibility of any forms of abuse of the recipient by the inducer in shared psychotic disorder...

Psychosis symptoms (delusions and hallucinations) are multifactorial in origin and, in later life, occur in the context of schizophrenia, delirium, dementia, delusional and schizophrenia-like disorders, mood disorders, and alcohol or substance abuse. The current article provides a clinical overview of very late-onset (after age 60) schizophrenia-like psychosis (VLOSLP), summarizing the literature on treatment options and reflecting on the role of psychiatric-mental health nurses (PMHNs). Increased awareness of the clinical presentation, key features, and evidence-based treatment options will assist PMHNs to confidently recognize this often under-diagnosed disorder and adopt a more assertive role in terms of engagement and follow up...

The authors present the case of a 24-year-old male with treatment-resistant schizophrenia, with predominant severe delusion and hallucination, who received bone marrow transplantation (BMT) for acute myeloid leukemia. After BMT, he showed a remarkable reduction in psychotic symptoms without administration of neuroleptics. He also showed drastic improvement in social functioning. Follow-up evaluations 2 and 4 years after BMT showed persistent significant improvement of the psychotic state and social functioning...

Schizophrenia is a pervasive neuropsychiatric disorder affecting over 1% of the world's population. Dopamine system dysfunction is strongly implicated in the etiology of schizophrenia. Data support the long-standing concept of schizophrenia as a disease characterized by hyperactivity within midbrain (striatal D2) dopamine systems. In addition, there is now considerable evidence that glutamate neurotransmission, mediated through NMDA-type receptors, is deficient in patients with schizophrenia and that hypoactivity in cortical dopamine and glutamate pathways is a key feature of this serious mental disorder...

OBJECTIVE: To examine the nature of the association between affective disorders and psychosis in Parkinson's disease (PD). BACKGROUND: In PD, psychosis and affective disorders are common and independently impact quality of life and mortality. Both depression and psychosis are correlated with the occurrence of cognitive dysfunction, suggesting that they may share neurobiological substrates. Anxiety has not been examined as a correlate of psychosis. METHODS: 144 PD subjects were evaluated with the Schedule for Assessment of Positive Symptoms to assess psychotic features, while depression and anxiety were examined by the Structured Clinical Interview for DSM-IV-TR (SCID) and self-assessment scales Beck Depression Inventory II (BDI-II) and Beck Anxiety Inventory (BAI)...

Dextromethorphan (3-methoxy-N-methylmorphinan), also known as "DXM" and "the poor man's PCP," is a synthetically produced drug that is available in more than 140 over-the-counter cough and cold preparations. Dextromethorphan (DXM) has overtaken codeine as the most widely used cough suppressant due to its availability, efficacy, and safety profile at directed doses. However, DXM is subject to abuse. When consumed at inappropriately high doses (over 1500 mg/day), DXM can induce a state of psychosis characterized by Phencyclidine (PCP)-like psychological symptoms, including delusions, hallucinations, and paranoia...

A decade has passed since the standardized remission criteria of schizophrenia spectrum disorders-the Andreasen Criteria-were defined. Over 2000 studies have been published, but only a few describe symptomatic remission over time. In this prospective study we followed patients for 3 and 5years, respectively. The aim was to investigate how different symptoms affect the occurrence of remission and how the remission cut-off level affects remission sustainability. The participants were patients diagnosed with schizophrenia spectrum disorders (DSM-IV)...

OBJECTIVE: Although many nursing home residents with dementia show agitation, hardly any literature is published about very frequent agitation. The WAALBED-III study focuses on the 2-week prevalence and correlates of very frequent agitation in these residents. DESIGN: Cross-sectional study using combined data of four studies. SETTING: One hundred nineteen dementia special care units in twenty-six nursing homes in The Netherlands. PARTICIPANTS: Two thousand seventy-four residents with dementia...

Kleine-Levin syndrome is a rare neuro-psychiatric disease. Most of the young patients are males who present with hypersomnia, cognitive dysfunction, altered perception, eating disorder (e.g. hyperphagia) or disinhibited behaviour (e.g. hypersexuality). Psychiatric symptoms such as apathy, delusions and hallucinations, depressed mood and compulsive behaviours also appear often and result frequently in a psychiatric referral. These symptoms, however, should be distinguished from those of psychiatric diseases as early as possible in order to ensure that patients do not receive the wrong treatment...

REVIEW
Aviv M Weinstein, Paola Rosca, Liana Fattore, Edythe D London
As part of an increasing worldwide use of designer drugs, recent use of compounds containing cathinones and synthetic cannabinoids is especially prevalent. Here, we reviewed current literature on the prevalence, epidemiology, bio-behavioral effects, and detection of these compounds. Gender differences and clinical effects will also be examined. Chronic use of synthetic cathinone compounds can have major effects on the central nervous system and can induce acute psychosis, hypomania, paranoid ideation, and delusions, similar to the effects of other better-known amphetamine-type stimulants...

OBJECTIVE: We have previously reported high dopamine D2/3 receptor occupancies at low amisulpride concentrations in older people with Alzheimer's disease (AD), during off-label treatment of AD-related psychosis. This post hoc analysis explored pharmacokinetic (concentration) and pharmacodynamic (prolactin, D2/3 occupancy) contributions to symptom reduction and extrapyramidal side effects (EPS) to inform AD-specific dose adjustments. METHODS: Population pharmacokinetic-pharmacodynamic models were developed by combining pharmacokinetic data from a phase 1 study in 20 healthy older people with pharmacokinetic prolactin, [¹⁸F]fallypride D2/3 receptor imaging, and clinical outcome data from 28 older patients prescribed open amisulpride (25-75 mg/d) to treat AD-related psychosis...

The two terms, pseudocyesis and delusion of pregnancy, were frequently used for pseudopregnancy. Delusion of pregnancy is a special form of hypochondriacal/somatic delusion reported in various psychiatric and organic disorders. The origin of the delusion of pregnancy in schizophrenia has often been explained by psycho-analytic interpretations attributing wish fulfilling, protective role to false beliefs, and mother establishes an undisturbed union with her fetus during pregnancy, which eliminate loneliness and helplessness...

REVIEW

There is growing recognition of the relationship between trauma, posttraumatic stress disorder (PTSD) and psychosis. There may be overlaps in casual mechanisms involved in the development of PTSD and psychosis following traumatic or adverse events. Trauma-focussed treatments found to be effective in treating PTSD may therefore represent a new direction in the psychological treatment of psychosis. This systematic review examined the literature on trauma-focussed treatments conducted with people with schizophrenia spectrum or psychotic disorders to determine effects on psychotic symptoms...
