ABSTRACT

Importance: Visual hallucinations are a core feature of dementia with Lewy bodies and primary psychiatric disease, yet identification of a hallucination vs normal spiritual experience depends on cultural context. Almost no information exists in the medical literature regarding normal spiritual experiences in American Indian participants in the context of a neurocognitive evaluation. Objective: To assess the characteristics of a normal spiritual experience in an Ojibwe Tribal Nation. Design, Setting, and Participants: This prospective, cross-sectional study was conducted between August 1, 2021, and August 31, 2022, among an Ojibwe Tribal Nation in northern Minnesota. Participants were evaluated at their tribal nation clinic. Cognitively unimpaired tribal Elders who were enrolled members of the tribal nation and aged 55 years or older were invited to participate via fliers, radio advertisements, and health fair presentations. Thirty-seven tribal Elders volunteered. Main Outcomes and Measures: Each participant was asked whether they experienced hallucinations or visions of people, animals, or objects that are not part of the physical world. This was an a priori formulated question and part of a comprehensive neurocognitive evaluation consisting of history and physical examination (including cognitive screening with a subspecialty-trained behavioral neurologist); blood tests for metabolic, nutritional, and thyroid conditions; and noncontrast magnetic resonance imaging brain scan. Four patients were excluded from the present analysis due to having mild cognitive impairment or dementia. Results: Thirty-three cognitively unimpaired tribal Elders (mean [SD] age, 66.0 [7.5] years; 22 women [67%]) were included. Sixteen (48%) answered affirmatively, reporting recurrent visions of the nonphysical world. Generally, these visions were well formed, benevolent in nature, and transient; started in preadolescence; involved spirits or ancestors; and were congruent with cultural and spiritual beliefs of the Ojibwe people. No patients had accompanying dream enactment behavior, dysautonomia, parkinsonism, sleep transition-related hallucinations, or moderate to severe depression to suggest a prodrome of an α-synucleinopathy, hypnopompic or hypnagogic hallucinations, or psychosis. Conclusions and Relevance: Although based on only 1 Ojibwe Tribal Nation, this study suggests that formed visions of the nonphysical world are common among cognitively healthy Ojibwe individuals and can represent normal spiritual experiences. Clinicians would benefit from careful consideration of cultural or spiritual context to avoid misdiagnosis of neuropsychiatric disease.

ABSTRACT

This article outlines the mental health burden of COVID-19 in the United Kingdom population, and presents preliminary evidence of less common psychiatric issues, such as paranoia and hallucinations, to which vulnerable groups in the U.K. population may be more vulnerable. It is argued that cognitive-behavioral therapy, with components of mindfulness, should be part of the therapeutic response. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

ABSTRACT

OBJECTIVE: This article describes the voice hearing experiences of a young Maori man, and the joint Maori healing and psychiatry assessment he received, in which the Maori healer (WN) concluded that some of the young man's experiences could be accounted for by ancestral kaitiaki (spiritual guardians). CONCLUSIONS: Kaitiaki are commonly accepted in Te Ao Maori (the Maori world) as an explanation for some types of voice hearing experiences. Collaboration between a Maori healer and a psychiatrist can offer Maori whanau (individuals and families) more appropriate mental health assessment and intervention than conventional psychiatric assessment alone when Maori spiritual experiences are suspected.

ABSTRACT

In the last decades, biological and environmental factors related to psychosis were investigated in individuals at ultra-risk for psychosis (UHR) to predict conversion. Although religion relates to psychosis in a variety of ways, it is understudied in subclinical samples. Therefore, we assessed the interplay between religion and prodromal symptoms in 79 UHR and 110 control individuals. They were interviewed with the Duke University Religion Index and the Structured Interview for Prodromal Syndromes (SIPS). Organizational religious activity, a measure of how often someone attends churches/temples, was positively related to perceptual abnormalities/hallucinations (Spearman's rho = 0.262, p = 0.02). This relationship was replicated in a path analysis model (ß = 0.342, SE = 0.108, p = 0.002), as well as a link between organizational religious activity and lower ideational richness (ß = 0.401, SE = 0.105, p = 0.000) with no influence of sex, age, religious denomination, or socioeconomic class. Intrinsic religious activity was negatively correlated with suspiciousness (SIPS P2) (ß = -0.028, SE = 0.009, p = 0.002), and non-organizational religious activity was correlated with higher ideational richness (N5) (ß = -0.220, SE = 0.097, p = 0.023). We hypothesize that subjects with subclinical psychosis may possibly use churches and other religious organizations to cope with hallucinations. Indeed, Brazil is characterized by a religious syncretism and a strong influence of Spiritism in the popular culture. The mediumistic idea that some might be able to hear and/or see spirits is probably employed to explain subclinical hallucinations in the lay knowledge. Our results emphasize the importance of assessing religion and other region-specific aspects of various cultures when studying UHR individuals. This sort of assessment would enhance understanding of differences in conversion rates, and would help to transpose prevention programs from high-income countries to other settings.

ABSTRACT

Objective: To explore the clinical predictors of freezing of gait (FOG) in Chinese patients with Parkinson's disease (PD). Methods: This study included 225 patients with PD who completed a three-year follow-up visit. The end-point was the presence of FOG (freezers), which was assessed during the follow-up visit. Group comparisons were conducted, followed by a further forward binary logistic regression analysis. Results: Eighty-five patients with PD (38%) had developed FOG at the end of study. At baseline, freezers exhibited higher age, longer disease duration, higher scores in Unified PD Rating Scale (UPDRS) III and Hamilton Depression/Anxiety Rating Scale, lower Frontal Assessment Battery (FAB) score, higher subscores (e.g., "urgency") and frequencies (e.g., "hallucinations") in Non-Motor Symptoms Scale, higher annual changes in MoCA, UPDRS III and FAB scores, and higher incidences of festination and falls than nonfreezers (p < .05). The forward binary logistic regression model indicated that a longer disease duration, a higher UPDRS III score, higher annual changes in UPDRS III score and "visuospatial/executive abilities" subscore, onset in lower limbs, and the presence of festination, falls, and hallucinations were associated with the development of FOG. Conclusions: Patients with onset in the lower limbs and the presence of festination, falls, and hallucinations may be prone to develop FOG episodes. FOG also likely occurs with the deterioration of PD severity and visuospatial function.

ABSTRACT

OBJECTIVE: Schizophrenia spectrum disorders (SSDs), are diagnosed more frequently among African-Americans (AAs) than Caucasians. It has been suggested that cultural differences in symptom presentation and endorsement (including reporting spiritual/religious experiences) may influence this disparity. The current study investigated the relationship between endorsement of spiritual auditory and visual hallucinations and subsequent diagnosis of SSD among AA patients. DESIGN: Participants (N = 471 AAs) completed the Mini International Neuropsychiatric Interview-Plus (MINI-Plus) Screening Interview as part of their intake to a HIV outpatient clinic. Endorsement of auditory or visual (A/V) hallucinations was explored with the MINI-Plus Psychotic Disorder Module and questions regarding the content of the unusual experience. RESULTS: Logistic regression indicated that endorsement of A/V hallucinations significantly predicted a SSD (OR = 41.6, 95% CI 13.7-126.0, p < .001). However, when hallucinations were spiritual in nature, odds of an SSD fell dramatically (OR = 0.22, 95% CI 0.07-0.64, p < .001). CONCLUSIONS: The current study indicates that not all visual and auditory hallucinations are symptomatic of a psychotic disorder in AA patients. Many of these experiences may be related to spirituality. Clinicians assessing AA patients need to query content of, meaning attributed to, and distress associated with A/V unusual experiences.

ABSTRACT

BACKGROUND: Psychotic symptoms are common among older adults and are seen in a wide range of conditions. Most studies examining the prevalence and correlates of psychotic symptoms among older adults have been conducted in Western populations. To address this gap the current study was undertaken to establish the prevalence and correlates of psychotic symptoms and paranoid ideation within a community sample of older adults without dementia in an Asian population. METHODS: The Well-being of the Singapore Elderly (WiSE) study was a comprehensive single phase, cross-sectional survey. All respondents were assessed using the Geriatric Mental State examination (GMS). Specific questions of the GMS were then used to establish the prevalence of hallucinations and persecutory delusions. RESULTS: A total of 2,565 respondents completed the study giving a response rate of 65.6%. The prevalence of any psychotic symptoms in this population of older adults was 5.2%. The odds of hallucinations and any psychotic symptoms were significantly higher among those of Malay ethnicity, and those who had no formal education. Older adults aged 75-84 years were significantly associated with lower odds of having hallucinations (vs. older adult aged 60-74 years), while homemaker status was significantly associated with lower odds of having any psychotic symptoms. CONCLUSIONS: The prevalence of psychotic symptoms among older Asian adults without dementia was higher than that reported from Western countries. Psychotic symptoms were associated with Malay ethnicity, poor cognitive performance and fewer years of schooling, visual and hearing impairment as well as depression and irritability.

ABSTRACT

Racism is a multidimensional construct that impacts risk for psychosis through various complex pathways. Previous research has yet to fully explore how major racial discriminatory events contribute to risk for psychotic experiences in the general population. We examined the National Survey of American Life to analyze the effects of 9 major racial discriminatory events on lifetime psychotic experiences among Black Americans. By examining each event separately, we found that police discrimination was associated with increased risk for lifetime psychotic experiences after adjusting for demographic variables, socioeconomic status, and co-occurring psychological or social problems. Being denied a promotion, being a victim of police abuse, and being discouraged from pursuing education were associated with lifetime visual hallucinations, and being discouraged from pursuing education was also associated with lifetime delusional ideation. None of the events were associated with lifetime auditory hallucinations. As a count of events, experiencing a greater range of major racial discriminatory events was associated with higher risk, particularly for lifetime visual hallucinations. Our findings point to the need for early detection and intervention efforts in community settings and multilevel efforts to eliminate racial discrimination. (PsycINFO Database Record

ABSTRACT

We present the case of a 28-year-old Afghan woman who presented perinatally with concerns of being possessed by jinns. She was noted to have third person auditory hallucinations, delusions of control and somatic passivity. She was diagnosed with schizophrenia and was treated with antipsychotic medications with a positive outcome. Her husband also believed that his wife was possessed and believed that her jinns talked through his wife on occasions. He did not experience any psychotic symptoms himself. In the Muslim faith, beliefs about jinns are widely held by people with and without any signs of mental illness. We feel that the patient's interpretation of her symptoms was influenced by her and her husband's religious and cultural beliefs, leading to a delay in receiving appropriate treatment. Awareness among mental health professionals about widely held religious and cultural beliefs will enhance the assessment, diagnosis and treatment of similar presentations.

ABSTRACT

Several studies have reported differences between African Americans and Caucasians in relative proportion of psychotic symptoms and disorders, but whether this reflects racial bias in the assessment of psychosis is unclear. The purpose of this study was to examine the distribution of psychotic symptoms and potential bias in symptoms assessed via semi-structured interview using a cohort of 3,389 African American and 5,692 Caucasian participants who were diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder. In this cohort, the diagnosis of schizophrenia was relatively more common, and the diagnosis of bipolar disorder and schizoaffective disorder-bipolar type was less relatively common, among African Americans than Caucasians. With regard to symptoms, relatively more African Americans than Caucasians endorsed hallucinations and delusions symptoms, and this pattern was striking among cases diagnosed with bipolar disorder and schizoaffective-bipolar disorder. In contrast, the relative endorsement of psychotic symptoms was more similar among cases diagnosed with schizophrenia and schizoaffective disorder-depressed type. Differential item function analysis revealed that African Americans with mild psychosis over-endorsed "hallucinations in any modality" and under-endorsed "widespread delusions" relative to Caucasians. Other symptoms did not show evidence of racial bias. Thus, racial bias in assessment of psychotic symptoms does not appear to explain differences in the proportion of symptoms between Caucasians and African Americans. Rather, this may reflect ascertainment bias, perhaps indicative of a disparity in access to services, or differential exposure to risk factors for psychosis by race. © 2015 Wiley Periodicals, Inc.

ABSTRACT

This study compares 20 subjects, in each of three different settings, with serious psychotic disorder (they meet inclusion criteria for schizophrenia) who hear voices, and compares their voice-hearing experience. We find that while there is much that is similar, there are notable differences in the kinds of voices that people seem to experience. In a California sample, people were more likely to describe their voices as intrusive unreal thoughts; in the South Indian sample, they were more likely to describe them as providing useful guidance; and in our West African sample, they were more likely to describe them as morally good and causally powerful. What we think we may be observing is that people who fall ill with serious psychotic disorder pay selective attention to a constant stream of many different auditory and quasi-auditory events because of different "cultural invitations"-variations in ways of thinking about minds, persons, spirits and so forth. Such a process is consistent with processes described in the cognitive psychology and psychiatric anthropology literature, but not yet described or understood with respect to cultural variations in auditory hallucinations. We call this process "social kindling."

ABSTRACT

The impact of self esteem and Locus of Control (LoC) on clinical presentation across different ethnic groups of patients at their first psychotic episode (FEP) remains unknown. We explored these constructs in 257 FEP patients (Black n=95; White British n=119) and 341 controls (Black n=70; White British n=226), and examined their relationship with symptom dimensions and pathways to care. FEP patients presented lower self-esteem and a more external LoC than controls. Lower self esteem was associated with a specific symptoms profile (more manic and less negative symptoms), and with factors predictive of poorer outcome (longer duration of untreated psychosis (DUP) and compulsory mode of admission). A more external LoC was associated with more negative symptoms and an insidious onset. When we explored these constructs across different ethnic groups, we found that Black patients had significantly higher self esteem than White British. This was again associated with specific symptom profiles. While British patients with lower self esteem were more likely to report delusions, hallucinations and negative symptoms, Black patients with a lower self esteem showed less disorganization symptoms. These findings suggest that self esteem and LoC may represent one way in which social experiences and contexts differentially influence vulnerable individuals along the pathway to psychosis.

ABSTRACT

PURPOSE: Despite evidence of the increased risk of psychotic disorders among ethnic minority adults, little is known about the effect of ethnic minority status to mild psychotic experiences among adolescents. This study investigated mild psychotic experiences in ethnic minority and majority adolescents in a Dutch representative general population sample, and tested the ethnic density effect in the classroom. METHODS: The CAPE was used to assess mild psychotic experiences among Dutch (n = 3,606) and non-Western ethnic minority pupils (n = 769). RESULTS: Ethnic minority adolescents showed higher levels of grandiosity and delusions than their ethnic majority peers, whereas no differences were found for hallucinations, paranormal beliefs and paranoia between both groups of adolescents. The ethnic density effect was partly confirmed for the ethnic majority: a decrease of ethnic majority pupils in class increased their feelings of paranoia. CONCLUSIONS: Because only some dimensions of mild psychotic experiences were affected by ethnic minority status or the interaction between ethnic minority status and ethnic class composition, our findings emphasize that mild psychotic experiences are multifactorial in origin, with different underlying processes.

ABSTRACT

INTRODUCTION: The symptom profile of schizophrenia can vary between ethnic groups. We explored selected symptom variables previously reported to be characteristic of schizophrenia in the Iban of Sarawak in transethnic populations from Australia, India, and Sarawak, Malaysia. We tested site differences to confirm previous research, and to explore implications of differences across populations for future investigations. METHODS: We recruited schizophrenia samples in Australia (n = 609), India (n = 310) and Sarawak (n = 205) primarily for the purposes of genetic studies. We analyzed seven identified variables and their relationship to site using logistic regression, including: global delusions, bizarre delusions, thought broadcast/insertion/withdrawal delusions, global hallucinations, auditory hallucinations, disorganized behavior, and prodromal duration. RESULTS: We identified a distinct symptom profile in our Sarawak sample. Specifically, the Iban exhibit: low frequency of thought broadcast/insertion/withdrawal delusions, high frequency of auditory hallucinations and disorganized behavior, with a comparatively short prodrome when compared with Australian and Indian populations. DISCUSSION: Understanding between-site variation in symptom profile may complement future transethnic genetic studies, and provide important clues as to the nature of differing schizophrenia expression across ethnically distinct groups. A comprehensive approach to subtyping schizophrenia is warranted, utilizing comprehensively ascertained transethnic samples to inform both schizophrenia genetics and nosology.

ABSTRACT

BACKGROUND: We still know little about whether and how the auditory hallucinations associated with serious psychotic disorder shift across cultural boundaries. AIMS: To compare auditory hallucinations across three different cultures, by means of an interview-based study. METHOD: An anthropologist and several psychiatrists interviewed participants from the USA, India and Ghana, each sample comprising 20 persons who heard voices and met the inclusion criteria of schizophrenia, about their experience of voices. RESULTS: Participants in the U.S.A. were more likely to use diagnostic labels and to report violent commands than those in India and Ghana, who were more likely than the Americans to report rich relationships with their voices and less likely to describe the voices as the sign of a violated mind. CONCLUSIONS: These observations suggest that the voice-hearing experiences of people with serious psychotic disorder are shaped by local culture. These differences may have clinical implications.

ABSTRACT

There is significant variation in the expression of schizophrenia across ethnically different populations, and the optimal structural and diagnostic representation of schizophrenia are contested. We contrasted both lifetime frequencies of DSM-IV criterion A (the core symptom criterion of the internationally recognized DSM classification system) symptoms and types/content of delusions and hallucinations in transethnic schizophrenia populations from Australia (n = 776), India (n = 504) and Sarawak, Malaysia (n = 259), to elucidate clinical heterogeneity. Differences in both criterion A symptom composition and symptom content were apparent. Indian individuals with schizophrenia reported negative symptoms more frequently than other sites, whereas individuals from Sarawak reported disorganized symptoms more frequently. Delusions of control and thought broadcast, insertion, or withdrawal were less frequent in Sarawak than Australia. Curiously, a subgroup of 20 Indian individuals with schizophrenia reported no lifetime delusions or hallucinations. These findings potentially challenge the long-held view in psychiatry that schizophrenia is fundamentally similar across cultural groups, with differences in only the content of psychotic symptoms, but equivalence in structural form.

ABSTRACT

A number of studies have explored hallucinations as complex experiences involving interactions between psychological, biological, and environmental factors and mechanisms. Nevertheless, relatively little attention has focused on the role of culture in shaping hallucinations. This article reviews the published research, drawing on the expertise of both anthropologists and psychologists. We argue that the extant body of work suggests that culture does indeed have a significant impact on the experience, understanding, and labeling of hallucinations and that there may be important theoretical and clinical consequences of that observation. We find that culture can affect what is identified as a hallucination, that there are different patterns of hallucination among the clinical and nonclinical populations, that hallucinations are often culturally meaningful, that hallucinations occur at different rates in different settings; that culture affects the meaning and characteristics of hallucinations associated with psychosis, and that the cultural variations of psychotic hallucinations may have implications for the clinical outcome of those who struggle with psychosis. We conclude that a clinician should never assume that the mere report of what seems to be a hallucination is necessarily a symptom of pathology and that the patient's cultural background needs to be taken into account when assessing and treating hallucinations.

ABSTRACT

Despite the recent proliferation of scientific, clinical, and narrative accounts of auditory verbal hallucinations (AVHs), the phenomenology of voice hearing remains opaque and undertheorized. In this article, we outline an interdisciplinary approach to understanding hallucinatory experiences which seeks to demonstrate the value of the humanities and social sciences to advancing knowledge in clinical research and practice. We argue that an interdisciplinary approach to the phenomenology of AVH utilizes rigorous and context-appropriate methodologies to analyze a wider range of first-person accounts of AVH at 3 contextual levels: (1) cultural, social, and historical; (2) experiential; and (3) biographical. We go on to show that there are significant potential benefits for voice hearers, clinicians, and researchers. These include (1) informing the development and refinement of subtypes of hallucinations within and across diagnostic categories; (2) "front-loading" research in cognitive neuroscience; and (3) suggesting new possibilities for therapeutic intervention. In conclusion, we argue that an interdisciplinary approach to the phenomenology of AVH can nourish the ethical core of scientific enquiry by challenging its interpretive paradigms, and offer voice hearers richer, potentially more empowering ways to make sense of their experiences.
