RESUMEN

BACKGROUND: There are, to date, limited and inconsistent findings concerning the relationship between insight and psychotic symptoms, despite some evidence in favor of the clinical and therapeutic relevance of the insight construct. We aimed to add to the pool of the available data in this area, by examining the correlations between the severity of insight and positive psychotic symptoms (delusions and auditory hallucinations), while accounting for self-stigma and attitudes towards medication, in a sample of long-stay inpatients with schizophrenia. METHODS: A cross-sectional study was conducted at the Psychiatric Hospital of the Cross, between July and October 2021. A total of 82 patients diagnosed with schizophrenia (aged 55.55 ± 10.21 years, 54.9% males) were enrolled. The semi-structured psychotic symptom rating scales, the Birchwood Insight Scale, the Belief About Medicine Questionnaire, and the Internalized Stigma of Mental Illness were used. RESULTS: The mean duration of illness in years was 30.15 ± 11.73, and the mean duration of hospitalization in years was 17.56 ± 9.24. Sixteen out of the 82 patients (19.5%) were considered as having poor insight. Bivariate analyses showed that higher chlorpromazine equivalent dose was significantly associated with more delusions, whereas higher insight was significantly associated with lower delusions. Multivariable analyses revealed that Higher chlorpromazine equivalent dose (Beta = 0.004) was significantly associated with more delusions, whereas higher insight (Beta = - 0.89) was significantly associated with less delusions. No significant associations were found between insight, self-stigma and hallucinations. CONCLUSION: Our results imply that more impaired insight is associated with greater severity of delusions, above and beyond the effects of self-stigma and medication doses. These findings are valuable to aid clinicians and researchers improve their understanding of the relationship insight-psychotic symptoms, and could help personalize prevention and early intervention strategies in schizophrenia.

RESUMEN

BACKGROUND: Till that date, a sparse body of research has been dedicated to perusing psychotic symptoms of sexual type, particularly in psychiatric populations. Our study's objective was to delineate psychotic symptoms with a sexual content, namely sexual delusions and hallucinations, among inpatients diagnosed with schizophrenia in Lebanon, and scrutinize their relationships with the severity of schizophrenia symptoms and childhood abusive events. METHODS: We conducted structured interviews with 167 chronic schizophrenia patients, who completed the Questionnaire for Psychotic Symptoms with a Sexual Content, the Child Abuse Self-Report Scale, and the Positive and Negative Syndrome Scale. RESULTS: 36.5% and 50.3% of the participants screened positive for current and lifetime episodes of sexual delusions and/or hallucinations, respectively. Alcohol drinking (aOR (adjusted odds ratio)current = 2.17; aORLifetime = 2.86) and increased psychological (aORcurrent = 1.09; aORLifetime = 1.09) and sexual (aORcurrent = 1.23; aORLifetime = 1.70) abuse were significantly associated with higher chances of experiencing current and lifetime sexual hallucinations and/or delusions. Additionally, an increased severity of schizophrenia symptoms (aOR = 1.02) was significantly associated with higher chances of current sexual hallucinations and/or delusions, whereas having a university level of education compared to primary (aOR = 0.15) was significantly associated with lower odds of current sexual hallucinations and/or delusions. CONCLUSION: In sum, our findings suggest that sexual psychotic symptoms are prevalent in chronic schizophrenia patients, providing support for their associations with antecedents of childhood traumatic experiences, illness severity, and substance use disorders. They endorse the vitalness of preventive measures against abuse, in order to circumvent such phenomenological outcomes. Our study offers the first data on sexual hallucinations and delusions in a non-Western psychiatric population, thus allowing clinicians and researchers to draw featural comparisons across different cultural settings.

RESUMEN

Corticobasal syndrome (CBS) is one of the Parkinson-plus disorders. While initially defined as a movement disorder rather than cognition, it is now known that CBS is related to various psychiatric symptoms. We describe a patient clinically diagnosed with CBS whose initial presentation was psychiatric and rather atypical. His clinical picture included psychotic depression and delusional jealousy. Misdiagnosing these syndromes may delay the initiation of the treatment and worsen the patients' condition, as well as increase the burden of the caretakers. Finally, COVID-19-related changes in the organization of health services complicated the diagnosis and follow-up processes of this patient.

RESUMEN

BACKGROUND: Cognitive models of psychosis postulate an important role of Theory of mind (ToM) in the formation and maintenance of delusions, but research on this plausible conjecture has gathered conflicting findings. In addition, it is still an open question whether problems in emotion recognition (ER) are associated with delusions. We examined the association of problems in ToM and ER with different aspects of delusions in a large sample of patients with psychosis enrolled in a therapy trial. This also enabled us to explore the possible impact of ToM and ER on one part of patients' social life: the quality of their therapeutic relationship. METHODS: Patients with psychotic disorders and delusions and/or hallucinations (n = 185) and healthy controls (n = 48) completed a ToM picture sequencing task and an ER task. Subsequently, patients were enrolled in a randomized-controlled Cognitive Behavior Therapy (CBT) trial (ISRCTN29242879). Patients and therapists rated the quality of the therapeutic relationship during the first five sessions of therapy. RESULTS: In comparison to controls, patients were impaired in both ToM and ER. Patients with deficits in ER experienced more severe delusional distress, whereas ToM problems were not related to delusions. In addition, deficits in ER predicted a less favorable therapeutic relationship and interactional problems viewed by the therapist. Impaired ER also moderated (increased) the negative influence of delusions on the therapeutic relationship and interactional difficulties viewed by the therapist. CONCLUSIONS: Cognitive models on the formation and maintenance of delusions should consider ER as a potential candidate that might be related to the formation and maintenance of delusional distress, whereas problems in ToM might not be directly related to delusions and secondary dimensions of delusions. In addition, problems in ER in patients with psychosis might have an impact on the quality of the therapeutic relationship and patients with problems in ER are more likely to be viewed as problematic by their therapists. Nevertheless, training ER might be a way to improve the quality of the therapeutic relationship and potentially the effectiveness of CBT or other interventions for patients with psychosis.

RESUMEN

Injustice, breach of trust, and humiliation are social stressors which can result in embitterment, known to everybody and which has been described in the Bible (Cain and Abel) or by Aristotle in the Nicomachean Ethics. It has been discussed by several authors since the early days of psychiatric classification. In the textbook 'Psychiatry' by E. Kraepelin a full chapter is devoted to 'querulant delusion', named a reactive psychosis, which can be discriminated from endogenous psychosis or personality disorders. Core symptoms are embitterment, negativism, helplessness, self blame, unspecific somatic symptoms, phobic avoidance of persons or situations related to the event, intrusions, phantasies of revenge and aggression. Another name is 'Posttraumatic Embitterment Disorder' according to the leading emotion. This severe mental disorder has by and large been ignored over the years by health professionals. In ICD-11 the term embitterment is mentioned for the first time in the category '6B43 adjustment disorder'. Embitterment can be measured with the 'Bern Embitterment Inventory (BVI)' and the 'Post-Traumatic Embitterment Self-rating Scale (PTED scale)'. Treatment must take into account the special features of embitterment including often aggressive rejection of help. A promising treatment approach is, to refer to wisdom psychology and transfer this in 'wisdom psychotherapy'.

RESUMEN

Malignant catatonia is a life-threatening syndrome, associated mostly with psychiatric diseases but also with neurological and neurodegenerative syndromes. We report the case of a 72-year-old patient, hospitalized for a major depressive episode with delusional symptoms, who presented a malignant catatonia. The patient had been transferred to an intensive care unit and treated with electroconvulsive therapy (ECT) leading to a rapid disappearance of the catatonic syndrome associated with a remission of the depressive symptoms. Complementary investigations helped us to secondarily diagnose a Lewy Body Dementia, which probably caused, associated with a treatment by haloperidol, the onset of catatonia. This case illustrates the need of an early diagnosis of neurodegenerative diseases in psychiatric outpatients and the importance of a quick management of catatonia, including ECT.

RESUMEN

PURPOSE OF REVIEW: Neuropsychiatric syndromes (NPS) are common in neurodegenerative disorders (NDD). This review describes the role of NPS in the diagnosis of NDD, criteria for the diagnosis of NPS, management of NPS, and agents in clinical trials for NPS. RECENT FINDINGS: NPS play an increasingly important role in the diagnosis of NDD. Consensus diagnostic criteria have evolved for psychosis, depression, agitation, and apathy in NDD. With one exception-pimavanserin is approved for the treatment of hallucinations and delusions in Parkinson's disease-there are no drugs approved by the FDA for treatment of NPS in NDD. Trials show that atypical antipsychotics reduce psychosis in AD and in Parkinson's disease, although side effect concerns have constrained their use. Antidepressants show benefit in treatment of Parkinson's disease with depression. Several agents are in clinical trials for treatment of NPS in NDD. Neuropsychiatric syndromes play a major role in NDD diagnosis. Clinical criteria allow recognition of NPS in NDD. Psychotropic medications are often useful in the treatment of NPS in NDD; efficacious, safe, and approved agents are needed.

RESUMEN

We describe an autopsy-proven case of Parkinson's disease with dementia showing early-onset delusions and hallucinations with limbic-type Lewy body pathology. A Japanese man 72 years old at time of death, developed hand tremor at the age of 45. On neurological examination at 47 years of age, parkinsonian symptoms and signs were present. Pergolide mesylate 1000 µg/day improved his motor symptoms. Then, delusional jealousy appeared and he consulted the psychiatric department in our hospital at the age of 50. Pergolide mesylate 2000 µg/day and trihexyphenidyl hydrochloride 6 mg/day were prescribed. His delusional jealousy made him hit his wife at the age of 63, and visual hallucinations were demonstrated. Brain magnetic resonance imaging (MRI) at the age of 65 revealed mild frontal lobe atrophy. At the age of 72, apparent dementia and dysphagia appeared. The total clinical course was 27 years. The brain showed mild frontal atrophy and weighed 1295 g before fixation. Depigmentation of the substantia nigra and locus ceruleus was macroscopically apparent. Neuronal loss with gliosis was noteworthy in the substantia nigra, locus ceruleus, dorsal vagal nucleus, nucleus basalis of Meynert (NBM), and intermediate lateral nuclei; however, cerebral neocortex and limbic systems were relatively preserved. Widespread occurrence of Lewy bodies with a few Lewy neurites were demonstrated (limbic-type). Noticeable Lewy body pathology in the NBM was shown in contrast to that in other limbic system structures, such as the amygdala and parahippocampal gyrus, and cerebral cortex. In vivo structural imaging studies revealed that cholinergic projections from the NBM could be responsible for generation of cholinergic deficiency syndrome, including delusions and hallucinations. Furthermore, basal forebrain volume is reduced in patients with Parkinson's disease showing visual hallucinations. Prominent Lewy body pathology in the NBM could be related to not only visual hallucinations but also delusions.

RESUMEN

BACKGROUND: Environment and culture are shown to be an important factor influencing characteristics of psychotic symptoms. Content of hallucinations and delusions is a projection of internal processes on external world. Religion plays a central role to lives of many people, but in schizophrenia religious experience and spirituality is confounded by psychotic symptoms. The aim of this study was to find how content of hallucinations and delusions interact with cultural conditions, that were changing over the decades. SUBJECTS AND METHODS: 100 of case histories from 2012 were randomly selected. From the medical record, content of hallucinations and delusion was extracted and categorized. Data from 2012 was compared with previous study by the authors, obtaining perspective of 80 years of history in the one hospital. RESULTS: Religious content of delusions and hallucinations appeared in 26% of patients. Diversity of the religious and spiritual themes in schizophrenia has been gradually decreasing. Many minor religious entities and figures such as "saints" and "angels" disappeared in 2012. Although, occurrence of contact with God and other religious figures was similar as in previous years, number of "visions" abruptly decreased. All of the religious content was culture-specific. CONCLUSIONS: Religious topics express general plasticity over a time, following cultural changes in society.

RESUMEN

Suicide prevention is a central topic of psychiatry and psychotherapy. Times of changes in psychiatric inpatient treatment conceptions usually come along with an increase of psychopathology and with increasing suicide rates in psychiatric hospitals to, like seen in the seventies and eighties of last century in Germany. After a real increase of inpatient suicides during those years the number and rate of inpatient suicides decreased from about 280 of 100 000 admissions of patients in 1980 to about 50 in 2014. Young male schizophrenic patients were identified as the new high risk group despite the severely depressed patients with delusions as a traditional high risk group. Nowadays suicide prevention is part of all educational programs in psychiatry and psychotherapy.

RESUMEN

MIT aims at progressively fostering metacognition until patients are able to understand what kind of interpersonal events or ideas about self and interpersonal interactions trigger their persecutory delusions and to question the delusional meaning they attribute to events.

RESUMEN

OBJECTIVE: To portray the emotional and behavioral reactions of persons with dementia to the delusions and hallucinations they experience, according to the reports of their family caregivers. The article also explores the relationship between those reactions and background variables. METHODS: Study participants were family caregivers of 74 older persons with a diagnosis of dementia (aged ≥ 65) residing in the community recruited from adult day centers and support groups for caregivers of persons with dementia and by advertising online. Assessments included the Behavioral Pathology in Alzheimer's Disease, the Neuropsychiatric Inventory, the Etiological Assessment of Psychotic Symptoms in Dementia, Activities of Daily Living questionnaire, and the Mini-Mental State Examination. RESULTS: Findings concerning emotional reactions reveal that close to half of the delusions resulted in discomfort, whereas around 40% did not. We found significant differences in the discomfort associated with different types of delusions, with delusions of abandonment, danger, and infidelity associated with more discomfort than other delusions. Around half of the delusions were associated with a behavioral manifestation. CONCLUSION: The findings highlight the need to examine the emotional impact of delusions and hallucinations as part of their assessment and as a consideration in treatment decisions.

RESUMEN

OBJECTIVES: Confabulations occur in schizophrenia and certain severe neuropsychiatric conditions, and to a lesser degree in healthy individuals. The present study used a forced confabulation paradigm to assess differences in confabulation between schizophrenia patients and healthy controls. METHODS: Schizophrenia patients (n=60) and healthy control participants (n=19) were shown a video with missing segments, asked to fill in the gaps with speculations, and tested on their memory for the story. Cognitive functions and severity of symptoms were also evaluated. RESULTS: Schizophrenia patients generated significantly more confabulations than healthy control participants and had a greater tendency to generate confabulations that were related to each other. Schizophrenic confabulations were positively associated with temporal context confusions and formal thought disorder, and negatively with delusions. CONCLUSIONS: Our findings show that the schizophrenia patients generate more confabulations than healthy controls and schizophrenic confabulations are associated with positive symptoms.

RESUMEN

Delusional misidentification syndromes (DMSs) are persistent delusions of hyper- or hypofamiliarity for meaningful persons and places in one's environment. This study set to determine the clinical course, neuroanatomical localization, neuropsychological abnormalities, and delusional content in patients with DMSs occurring after focal neurological injuries. Sixty-one patients were identified: 28 with hypofamiliar delusions, 27 with hyperfamiliar delusions, and, most surprisingly, six patients with both hypo- and hyperfamiliar delusions. Recognition is often delayed by months from the time of injury, and the delusions are self-limited. Patients with DMSs had right hemisphere (92%) injuries (specifically right frontal injuries in 63%), prominent memory impairment (73%), and multiple concurrent DMSs (29%).

RESUMEN

The perception of the bodily self in space is a composite cognitive function requiring a dynamic integrated brain mechanism. Somatoparaphrenia (SP), a delusional belief concerning the experienced disownership for the contralesional paralyzed arm, represents the disruption of such mechanism. In two experiments, we have investigated the alteration of limb disownership after spatial manipulations in a right-brain-damaged patient affected by chronic SP. In experiment 1 the patient's spatial attention was switched between the left and right sides of space. SP signs worsened when the patient was interviewed from the left compared to the right bedside. In the second experiment we showed the first systematic transient remission of SP using left caloric vestibular stimulation (CVS), a physiologic manipulation mainly acting on the spatial frame of reference. Taken together, these results shed further light on the spatial nuance of SP and on the importance of vestibular signals for the generation of a coherent body representation. Furthermore, our case study demonstrated the possibility of eliciting more severe SP signs if the patient is interviewed from the left bedside. Additionally, CVS applications may have an important impact on the rehabilitation of these symptoms.

RESUMEN

Dementia with Lewy bodies (DLB) is recognised as the second most common form of dementia in older people. Delirium is a condition of acute brain dysfunction for which a pre-existing diagnosis of dementia is a risk factor. Conversely delirium is associated with an increased risk of developing dementia. The reasons for this bidirectional relationship are not well understood. Our aim was to review possible similarities in the clinical presentation and pathophysiology between delirium and DLB, and explore possible links between these diagnoses. A systematic search using Medline, Embase and Psychinfo was performed. References were scanned for relevant articles, supplemented by articles identified from reference lists and those known to the authors. 94 articles were selected for inclusion in the review. Delirium and DLB share a number of clinical similarities, including global impairment of cognition, fluctuations in attention and perceptual abnormalities. Delirium is a frequent presenting feature of DLB. In terms of pathophysiological mechanisms, cholinergic dysfunction and genetics may provide a common link. Neuroimaging studies suggest a brain vulnerability in delirium which may also occur in dementia. The basal ganglia, which play a key role in DLB, have also been implicated in delirium. The role of Cerebrospinal fluid (CSF) and serum biomarkers for both diagnoses is an interesting area although some results are conflicting and further work in this area is needed. Delirium and DLB share a number of features and we hypothesise that delirium may, in some cases, represent early or 'prodromal' DLB. Further research is needed to test the novel hypothesis that delirium may be an early marker for future DLB, which would aid early diagnosis of DLB and identify those at high risk.

RESUMEN

BACKGROUND: There has been increasing interest in the association between childhood trauma and psychosis. Proposals for potential mechanisms involved include affective dysregulation and cognitive appraisals of threat. AIMS: To establish if, within bipolar disorder, childhood events show a significant association with psychosis, and in particular with symptoms driven by dysregulation of mood or with a persecutory content. METHOD: Data on lifetime-ever presence of psychotic symptoms were determined by detailed structured interview with case-note review (n = 2019). Childhood events were recorded using a self-report questionnaire and case-note information. RESULTS: There was no relationship between childhood events, or childhood abuse, and psychosis per se. Childhood events were not associated with an increased risk of persecutory or other delusions. Significant associations were found between childhood abuse and auditory hallucinations, strongest between sexual abuse and mood congruent or abusive voices. These relationships remain significant even after controlling for lifetime-ever cannabis misuse. CONCLUSIONS: Within affective disorder, the relationship between childhood events and psychosis appears to be relatively symptom-specific. It is possible that the pathways leading to psychotic symptoms differ, with delusions and non-hallucinatory symptoms being influenced less by childhood or early environmental experience.

RESUMEN

BACKGROUND: Several clinical studies point to a high prevalence of psychotic symptoms in frontotemporal dementia associated with C9ORF72 mutations, but clinicopathological studies addressing the association between C9ORF72 mutations and delusions are lacking. METHOD: Seventeen patients with pathologically proven frontotemporal lobar degeneration (FTLD) associated with C9ORF72 mutations were identified from Neurodegenerative Disease Brain Bank. Of the 17 cases with C9ORF72 mutation, 4 exhibited well-defined delusions. The clinical history, neurological examination, neuropsychological testing, neuroimaging analysis, and postmortem assessment of the patients with delusions were evaluated and compared with the other cases. RESULT: The content of the delusions was mixed including persecution, infidelity, and grandiosity. All cases showed parkinsonism; voxel-based morphometry analysis showed greater precuneus atrophy in patients with delusions than those without delusions. All 4 had unclassifiable FTLD with TAR DNA-binding protein inclusions, with characteristics of both type A and type B. Three cases had additional τ pathology and another had α-synuclein pathology. CONCLUSION: C9ORF72 carriers with well-defined delusions likely associated with additional pathologies and parietal atrophy in neuroimaging. Patients presenting with middle-aged onset of delusions should be screened for C9ORF72 mutations, especially if family history and parkinsonism are present.
