The auditory-verbal hallucinations of Welsh-English bilingual people

Executive control of language in schizophrenia patients with history of auditory verbal hallucinations: A neuropsychological and resting-state fMRI study

BACKGROUND

As demonstrated by a plethora of studies, compromised executive functions (EF) and language are implicated in mechanisms of auditory verbal hallucinations (AVH), but the contribution of their interaction to AVH remains unclear. We hypothesized that schizophrenia patients with history of AVH (AVHh+) vs. without history of AVH (AVHh-) have a specific deficit of executive control of language and alterations in functional connectivity (FC) between the brain regions involved in EF and language, and these neuropsychological and neurophysiological traits are associated with each other.

METHODS

To explore the executive control of language and its contribution to AVH, we used an integrative approach involving analysis of neuropsychological and resting-state fMRI data of 34 AVHh+, 16 AVHh-, and 40 healthy controls. We identified the neuropsychological and FC measures that differentiated between AVHh+, AVHh-, and HC, and tested the associations between them.

RESULTS

AVHh+ were characterized by decreased category and phonological verbal fluency, utterance length, productivity in the planning tasks, and poorer retelling. AVHh+ had decreased FC between the left inferior frontal gyrus and the anterior cingulate cortex. Productivity in category verbal fluency was associated with the FC between these regions.

CONCLUSIONS

Poor executive control of word retrieval and deficient programming of sentence and narrative related to more general deficits of planning may be the neuropsychological traits specific for AVHh+. A neurophysiological trait specific for AVHh+ may be a decreased FC between regions involved in language production and differentiation between alien- vs. self-generated speech and between language production vs. comprehension.

Migrant status, clinical symptoms and functional outcome in youth at clinical high risk for psychosis: findings from the NAPLS-3 study

PURPOSE

Migrant status is a known risk factor for psychosis, but the underlying causes of this vulnerability are poorly understood. Recently, studies have begun to explore whether migrant status predicts transition to psychosis in individuals at clinical high risk (CHR) for psychosis. Results, however, have been inconclusive. The present study assessed the impact of migrant status on clinical symptoms and functional outcome in individuals at CHR for psychosis who took part in the NAPLS-3 study.

METHODS

Participants' migrant status was classified as native-born, first-generation, or second-generation migrant. Clinical symptoms were assessed using the Structured Interview for Psychosis-Risk Syndromes (SIPS); functional outcome was measured using the Global Functioning Scales:Social and Role (GF:S; GF:R). Assessments were conducted at baseline, 12-months, 18-months, and 24-months follow-up. Generalized linear mixed models for repeated measures were used to examine changes over time and differences between groups.

RESULTS

The overall sample included 710 individuals at CHR for psychosis (54.2% males; Age: M = 18.19; SD = 4.04). A mixed model analysis was conducted, and no significant differences between groups in symptoms or functioning were observed at any time point. Over time, significant improvement in symptoms and functioning was observed within each group. Transition rates did not differ across groups.

CONCLUSION

We discuss potential factors that might explain the lack of group differences. Overall, migrants are a heterogeneous population. Discerning the impact of migration from that of neighborhood ethnic density, social disadvantage or socio-economic status of different ethnic groups could help better understand vulnerability and resilience to psychosis.

Encapsulating psychosis with a second language: A clinical case

The percentage of individuals who are functionally bilingual in the United States has grown substantially in the last 3 to 4 decades. Nevertheless, bilingual mental health providers remain relatively scarce and bilingualism in psychosis or schizophreniaspectrum disorders remains relatively unexplored. Here, we present a clinical case study of a man with schizophrenia who presented his psychotic symptoms differently in his primary and secondary languages. We also consider this case in the context of other published cases with similar themes. Based on our review, we hypothesize that the presentation of psychotic symptoms may be influenced by the language a person uses, and more specifically, by their cognitive abilities to speak that language and/or their emotional attachment to that language. We outline the importance of obtaining a thorough language background of each patient with psychosis and investigate the ways in which a second language could serve as a protective factor against functional decline in psychotic and healthy populations. We suggest that attempts to engage bilingual patients with psychosis clinically in each language could lead to a more holistic evaluation of psychotic and disorganized symptoms and thus lead to more multidimensional intervention strategies.

Characterizing individuals accessing mental health services in the UAE: a focus on youth living in Dubai

Background

Most mental health issues develop during adolescence, therefore identifying youth mental health needs and pathways to care is critical to improve prevention. To date, studies have typically focused on Western samples, while the impact of cultural diversity on perception of health and illness, and pathways to care, remain poorly understood. To address the shortage of studies conducted in the Arab world, and particularly in the United Arab Emirates (UAE), the present investigation aims to identify the characteristics of youth accessing mental health services in Dubai.

Methods

Data was collected retrospectively from patients’ records at Rashid Hospital Child Psychiatry Service. Information collected included demographics, life stressors, symptoms duration, main diagnosis, and presence/absence of psychotic features in patients’ symptomatology. The relationship between demographic and clinical variables was explored using Chi-square tests and negative binomial regression models.

Results

The sample included 99 treatment-seeking young patients (mean age 15.3; SD = 1.7); 47.5 % were Emirati (UAE national) and 52.5 % were non-Emirati patients. In our treatment-seeking youth sample Depressive disorders represented the most frequent diagnosis, followed by Bipolar and related disorders, Anxiety and stress related disorders, and Schizophrenia and psychotic disorders. Compared to Emirati patients, non-Emirati patients were more likely to report relationships with friends as a source of stress. Female help-seekers, compared to males, were more likely to report stressful relationships with family members, and to receive a diagnosis of Depressive disorders. The duration of symptoms before seeking help was significantly predicted by family stress, gender, self-harm behavior, a symptomatology with psychotic features, and a diagnosis of Anxiety disorders.

Conclusions

The present study contributes to characterizing youth accessing mental health services at Rashid Hospital’s Child Psychiatry service in Dubai. An overall prevalence of poor family functioning among help-seeking youth, and the importance of peer support for expatriate youth were highlighted. Gender differences in perceived stressors, diagnoses and help-seeking behavior suggest the need to promote help-seeking among young boys. While presentation with psychotic features seems to lead to quicker access to medical care, self-harm and anxiety appear to delay help-seeking. The potential implications of our results for promoting youth wellbeing in the region are discussed.
