Asylum-seeking children with severe loss of activities of daily living: clinical signs and course during rehabilitation

The neurobiology of functional neurological disorders characterised by impaired awareness

We review the neurobiology of Functional Neurological Disorders (FND), i.e., neurological disorders not explained by currently identifiable histopathological processes, in order to focus on those characterised by impaired awareness (functionally impaired awareness disorders, FIAD), and especially, on the paradigmatic case of Resignation Syndrome (RS). We thus provide an improved more integrated theory of FIAD, able to guide both research priorities and the diagnostic formulation of FIAD. We systematically address the diverse spectrum of clinical presentations of FND with impaired awareness, and offer a new framework for understanding FIAD. We find that unraveling the historical development of neurobiological theory of FIAD is of paramount importance for its current understanding. Then, we integrate contemporary clinical material in order to contextualise the neurobiology of FIAD within social, cultural, and psychological perspectives. We thus review neuro-computational insights in FND in general, to arrive at a more coherent account of FIAD. FIAD may be based on maladaptive predictive coding, shaped by stress, attention, uncertainty, and, ultimately, neurally encoded beliefs and their updates. We also critically appraise arguments in support of and against such Bayesian models. Finally, we discuss implications of our theoretical account and provide pointers towards an improved clinical diagnostic formulation of FIAD. We suggest directions for future research towards a more unified theory on which future interventions and management strategies could be based, as effective treatments and clinical trial evidence remain limited.

Separation and not residency permit restores function in resignation syndrome: a retrospective cohort study

Despite poor treatment results, a family-oriented approach and the securing of residency have been deemed essential to recovery from resignation syndrome (RS). In a retrospective cohort study, we evaluated an alternative method involving environmental therapy, with patients separated from their parents, while actively abstaining from involving the asylum process in treatment. We examined medical records, social services acts, and residential care home acts from 13 individuals treated at Solsidan residential care home between 2005 and 2020. Severity and outcome were assessed with Clinical Global Impression, Severity and Improvement subscales. Thirteen participants were included and out of these nine (69%) recovered, i.e. they very much or much improved. Out of the eight that were separated, all recovered, also, one non-separated recovered. The difference in outcome between subjects separated and not was significant (p = 0.007). Moreover, out of the five which received a residency permit during treatment, one recovered whereas four did not. The difference in outcome between subjects granted residency and not was significant (p = 0.007). The data revealed three (23%) cases of simulation where parents were suspected to have instigated symptoms. Our evaluation suggests that separation from parents and abstaining from invoking residency permit could be essential components when treating RS. Relying on a family-oriented approach, and residency could even be detrimental to recovery. The examined intervention was successful also in cases of probable malingering by proxy.

Suicide rates and suicidal behaviour in displaced people: A systematic review

Background

Refugees, and other forcibly displaced people, face mental distress and may be disproportionately affected by risk factors for suicide. Little is known about suicidal behaviour in these highly mobile populations because collecting timely, relevant, and reliable data is challenging.

Methods and findings

A systematic review was performed to identify studies of any design reporting on suicide, suicide attempts, or suicidal ideation among populations of displaced people. A sensitive electronic database search was performed in August 2020, and all retrieved studies were screened for relevance by two authors. Studies were categorised by the population being evaluated: refugees granted asylum, refugees living in temporary camps, asylum seekers, or internally displaced people. We distinguished between whether the sampling procedure in the studies was likely to be representative, or the sample examined a specific non-representative subgroup of displaced people (such as those already diagnosed with mental illness). Data on the rates of suicide or the prevalence of suicide attempts or suicidal ideation were extracted by one reviewer and verified by a second reviewer from each study and converted to common metrics. After screening 4347 articles, 87 reports of 77 unique studies were included. Of these, 53 were studies in representative samples, and 24 were based on samples of specific target populations. Most studies were conducted in high-income countries, and the most studied population subgroup was refugees granted asylum. There was substantial heterogeneity across data sources and measurement instruments utilised. Sample sizes of displaced people ranged from 33 to 196,941 in studies using general samples. Suicide rates varied considerably, from 4 to 290 per 100,000 person-years across studies. Only 8 studies were identified that compared suicide rates with the host population. The prevalence of suicide attempts ranged from 0.14% to 15.1% across all studies and varied according to the prevalence period evaluated. Suicidal ideation prevalence varied from 0.17% to 70.6% across studies. Among refugees granted asylum, there was evidence of a lower risk of suicide compared with the host population in 4 of 5 studies. In contrast, in asylum seekers there was evidence of a higher suicide risk in 2 of 3 studies, and of a higher risk of suicidal ideation among refugees living in camps in 2 of 3 studies compared to host populations.

Conclusion

While multiple studies overall have been published in the literature on this topic, the evidence base is still sparse for refugees in camps, asylum seekers, and internally displaced people. Less than half of the included studies reported on suicide or suicide attempt outcomes, with most reporting on suicidal ideation. International research networks could usefully define criteria, definitions, and study designs to help standardise and facilitate more research in this important area.

Health-related quality of life in refugee minors from Syria, Iraq and Afghanistan resettled in Sweden: a nation-wide, cross-sectional study

PURPOSE

To examine health-related quality of life (HRQoL) in refugee minors resettled in Sweden and compare results to a European reference population, while exploring associations between sociodemographic factors and HRQoL dimensions.

METHODS

A cross-sectional, nation-wide study was conducted with a stratified sample of refugee minors ages 12-15 and 16-18 from Afghanistan, Iraq and Syria, resettled in Sweden between 2014 and 2018. HRQoL was measured using KIDSCREEN-27. HRQoL dimension scores of the sample were compared to mean scores of European age and gender-matched reference population. Associations between sociodemographic factors and HRQoL dimensions were investigated with independent t tests and ANOVA. A multivariable regression analysis was performed to identify the sociodemographic factors associated with HRQoL.

RESULTS

The questionnaire was sent to 10,000 potential respondents. The response rate was 26%, yielding n = 2559 refugee minors (boys 55%, girls 45%) in the study sample. Compared to European references, minors in the present study had significantly lower scores of HRQoL within psychological wellbeing and peers and social support, whereas levels for autonomy and parent/guardian relations and school environment were higher. Several sociodemographic factors were significantly associated with all HRQoL dimensions, with those 16-18 years old, having average or poor family economy, and living with an unrelated adult or family reporting lower levels of HRQoL. Minors from Afghanistan had significantly lower scores of HRQoL for all dimensions compared to those from Iraq and Syria.

CONCLUSION

Refugee minors had significantly lower levels of HRQoL for psychological wellbeing and peers and social support compared to European references. Future research should further investigate this potential HRQoL gap further.

Epilepsy and psychogenic non-epileptic seizures in forcibly displaced people: A scoping review

With a growing number of forcibly displaced people (FDP) globally, the focus on their medical needs has necessarily increased. Studies about the prevalence and incidence of epilepsy and psychogenic non-epileptic seizures (PNES) in this population are, though, sparse. This Review highlights the importance of exploring and managing both conditions in these vulnerable people to promote global health. We performed an exhaustive review of 10 databases, as well as a manual search of relevant websites related to global health and refugee-related organizations. We analyzed data related to the prevalence and incidence of epilepsy and PNES; health visits; costs of medical care and challenges faced by healthcare workers in relation to FDP with these conditions. Fifty six papers met our inclusion criteria. Of these, 53 reported directly or indirectly on the prevalence of epilepsy and its costs in FDP. Two articles reported on the prevalence of PNES in forcibly displaced people. The reported prevalence of epilepsy in FDP varied from 0.2% to 39.13%, being highest in people with pre-existing neurological or psychiatric comorbidities. Only one study reported on the incidence of epilepsy in internally displaced children. Data from the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) have identified a tendency to higher incidence of epilepsy in children following wars. While within displaced women without a history of sexual violence the rate of PNES was 16.7%, in FDP women with such a history the rate of PNES was 43.7% (p=0.02). The healthcare costs for epilepsy can be high, with recurrent health visits related to seizures being the most common cause of health encounters in refugee camps. Increasing awareness and further studies of multicultural aspects to improve shared understanding of seizure phenomenon in vulnerable displaced populations would seem crucial.

Pervasive refusal syndrome: systematic review of case reports

Pervasive refusal syndrome (PRS) is a complex condition that affects young people leading to social withdrawal, inability or refusal to eat, drink, mobilise or speak. The affected individual regresses and is unable to self-care and quite characteristically will resist rehabilitation, worsen with praise or remain entirely passive. This systematic review was aimed at describing clinical features of PRS, current interventions and to summarise some of the nosological aspects of the condition. Without language restriction, an electronic search was conducted in Embase, PsychInfo, Medline, Cochrane library, and PubMed databases yielding 29 articles with a total of 79 cases. We performed a risk of assessment bias using an adapted Newcastle-Ottawa Scale and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. 124 articles were identified, of which 29 were included and these yielded 79 cases. Seventy-six percent of the studies had a low rate of risk of assessment bias (good quality). Our results show that PRS overlaps with several conditions, mainly affects young females aged 7-15 years and has a recovery rate of 78% if diagnosed and treated early but the duration of inpatient treatment may last up to 9.44 months (8.82 SD). The patients had multiple inter-dependent risks. The major predisposing factors included vulnerable premorbid personality and pre-existing mental disorder. Precipitating factors were stressors such as infection and traumatic experiences. Enmeshed parent-child relationship served as a maintaining factor. The themes of treatment approach are essentially rehabilitative: (1) working collaboratively with patient and family, (2) having access to multidisciplinary team, and (3) peer/group supervision. This study has systematically evaluated a large sample of patients with PRS to ascertain its clinical features and the core elements of its treatment. Its key treatment approach is a multi-modal rehabilitative strategy that is compassionate, transparent and inclusive.

Asylum-seeking children with resignation syndrome: catatonia or traumatic withdrawal syndrome?

In the beginning of the 2000s, an increasing number of asylum-seeking children in Sweden fell into a stuporous condition. In the present study, we report 46 consecutive children with the most severe form of this illness where the children were unable to give any response at all, did not react to pain, cold or touching, could not be supported to sit or stand on their feet, could not do anything when requested, and in most cases had enuresis/encopresis. A minority of the children came from war zones (n = 8, 17.4%). A majority belonged to an ethnic or religious minority (n = 32, 69.6%) in their homeland and almost all were persecuted (n = 43, 93.5%). All had either experienced violence themselves or had witnessed or heard about violence against close family members. The age of onset of the first symptom of illness for boys was 11.2 years [CI 9.6-12.8], for girls 11.8 yrs.[CI 10.4-13.2], and the age for falling into stupor for boys was 12.9 years [CI 11.6-14.1] years and was the same for girls, 12.9 years [CI 11.6-14.2] years. Girls tended to have depression before entering the stuporous condition, while the boys tended to have PTSD first (Chi-square = 3.73, p = 0.054). A majority of the children had one (n = 13, 28.3%) or both parents (n = 14, 30.4%) suffering from mental or severe physical disorder. It is discussed whether the presented condition is a separate entity or if the syndrome should be regarded as a variant of catatonia, and whether benzodiazepines should be tried.

Pervasive refusal syndrome in asylum-seeking children: Review of the current evidence

This study reviews the current evidence in pervasive refusal syndrome (PRS) in asylum-seeking children. Refugees can experience a variety of traumas throughout the process of migration. Children can be exposed to multiple traumas such as experienced or witnessed physical or sexual violence, loss and bereavement, parental separation and the threat of persecution and/or kidnapping. The third stage of the migration journey can add further stress; children and families may experience multiple rejections of asylum application effectively living in limbo with the constant threat of deportation. High rates of mental health disorder are well documented in young asylum seekers, particularly depression, anxiety and post-traumatic stress disorder (PTSD). PRS is less frequently described but nonetheless a severe and life-threatening condition affecting young asylum seekers. Traumatisation, cultural factors and hostile asylum processes are specific moderating factors seen in asylum-seeking children. Asylum-seeking children normally make a full recovery from PRS. This study suggests a link between prolonged asylum processes and hostile foreign policy in developing and maintaining illness; similar cases are now being reported in other countries with hostile foreign policies. These findings are therefore relevant to clinicians and politicians working with this vulnerable group.

Practitioner Review: Mental health problems of refugee children and adolescents and their management

BACKGROUND

Since 2010, the numbers of refugees have increased and around half are under 18 years of age. It is known that experience of organised violence, displacement and resettlement increases the risk for psychiatric disorders and psychosocial impairment. This review integrates recent research into the risk and protective factors for psychopathology with service and treatment issues.

METHODS

We draw on and critically evaluate key systematic reviews in the selected areas, innovative robust studies and relevant government reports.

RESULTS

Many refugee children show resilience and function well, even in the face of substantial adversities. The most robust findings for psychopathology are that PTSD, and posttraumatic and depressive symptoms are found at higher prevalence in those who have been exposed to war experiences. Their severity may decrease over time with resettlement, but PTSD in the most exposed may show higher continuity. More severe psychiatric disorders including psychosis may also occur. Service delivery needs to take into account socioeconomic and cultural influences but, given the high level of unmet need even in high-income countries, stepped care delivery is required. The evaluation of psychological interventions, often delivered in group settings, suggests that they can be effective for many distressed children; however, for the more impaired, a greater range of disorder-specific therapies will be required.

CONCLUSIONS

Child and adolescent mental health clinicians and service providers need to be aware of the specific needs of this population and systems for service delivery. There are significant knowledge gaps in understanding risk and vulnerability, service delivery and treatment effectiveness.

Agency, embodiment and enactment in psychosomatic theory and practice

In this paper, we examine some of the conceptual, pragmatic and moral dilemmas intrinsic to psychosomatic explanation in medicine, psychiatry and psychology. Psychosomatic explanation invokes a social grey zone in which ambiguities and conflicts about agency, causality and moral responsibility abound. This conflict reflects the deep-seated dualism in Western ontology and concepts of personhood that plays out in psychosomatic research, theory and practice. Illnesses that are seen as psychologically mediated tend also to be viewed as less real or legitimate. New forms of this dualism are evident in philosophical attacks on Engel's biopsychosocial approach, which was a mainstay of earlier psychosomatic theory, and in the recent Research Domain Criteria research programme of the US National institute of Mental Health which opts for exclusively biological modes of explanation of illness. We use the example of resignation syndrome among refugee children in Sweden to show how efforts to account for such medically unexplained symptoms raise problems of the ascription of agency. We argue for an integrative multilevel approach that builds on recent work in embodied and enactive cognitive science. On this view, agency can have many fine gradations that emerge through looping effects that link neurophenomenology, narrative practices and cultural affordances in particular social contexts. This multilevel ecosocial view points the way towards a renewed biopsychosocial approach in training and clinical practice that can advance person-centred medicine and psychiatry.

Resignation Syndrome: Catatonia? Culture-Bound?

Resignation syndrome (RS) designates a long-standing disorder predominately affecting psychologically traumatized children and adolescents in the midst of a strenuous and lengthy migration process. Typically a depressive onset is followed by gradual withdrawal progressing via stupor into a state that prompts tube feeding and is characterized by failure to respond even to painful stimuli. The patient is seemingly unconscious. Recovery ensues within months to years and is claimed to be dependent on the restoration of hope to the family. Descriptions of disorders resembling RS can be found in the literature and the condition is unlikely novel. Nevertheless, the magnitude and geographical distribution stand out. Several hundred cases have been reported exclusively in Sweden in the past decade prompting the Swedish National Board of Health and Welfare to recognize RS as a separate diagnostic entity. The currently prevailing stress hypothesis fails to account for the regional distribution and contributes little to treatment. Consequently, a re-evaluation of diagnostics and treatment is required. Psychogenic catatonia is proposed to supply the best fit with the clinical presentation. Treatment response, altered brain metabolism or preserved awareness would support this hypothesis. Epidemiological data suggests culture-bound beliefs and expectations to generate and direct symptom expression and we argue that culture-bound psychogenesis can accommodate the endemic distribution. Last, we review recent models of predictive coding indicating how expectation processes are crucially involved in the placebo and nocebo effect, delusions and conversion disorders. Building on this theoretical framework we propose a neurobiological model of RS in which the impact of overwhelming negative expectations are directly causative of the down-regulation of higher order and lower order behavioral systems in particularly vulnerable individuals.

Pervasive refusal syndrome (PRS) 21 years on: a re-conceptualisation and a renaming

Twenty-one years ago, Lask and colleagues first described pervasive refusal syndrome (PRS) as a child's "dramatic social withdrawal and determined refusal to walk, talk, eat, drink, or care for themselves in any way for several months" in the absence of an organic explanation. PRS has been conceptualised in a variety of ways since then. These have included a form of post-traumatic stress disorder, learnt helplessness, 'lethal mothering', loss of the internal parent, apathy or the 'giving-up' syndrome, depressive devitalisation, primitive 'freeze', severe loss of activities of daily living and 'manipulative' illness, meaning the possibility that the children have been drugged to increase chances of asylum in asylum-seeking families. Others have insisted that PRS is simply depression, conversion disorder, catatonia or a factitious condition. This paper reviews these conceptualisations, explores some of the central complexities around PRS and proposes a neurobiological explanatory model, based upon autonomic system hyper-arousal. It touches upon the clinical implications and suggests a new name for the condition reflecting what we believe to be a more sophisticated understanding of the disorder than was available when it was first described.

Pervasive refusal syndrome among inpatient asylum-seeking children and adolescents: a follow-up study

BACKGROUND

Pervasive refusal syndrome (PRS) is a rare but severe condition, characterised by social withdrawal and a pervasive active refusal in terms of eating, mobilisation, speech and personal hygiene. PRS has been proposed as a new diagnostic entity in child and adolescent psychiatry, although the diagnostic criteria are debated. In the past 10 years there has been an increase in PRS symptoms among asylum-seeking children and adolescents in Sweden. Here, we describe five cases of PRS among asylum-seeking children and adolescents.

METHOD

Three females and 2 males, 7-17 years of age with the clinical picture of PRS, treated as inpatients at the Department of Child and Adolescent Psychiatry, Malmö, Sweden, 2002-2010, were analysed on the basis of their medical records. Subjects were diagnosed using previously suggested criteria for PRS. At follow-up, a semi-structured interview focusing on the inpatient stay and current status was performed. The subjects were assessed with Global Assessment of Functioning (GAF) and self-rating questionnaires regarding depression and post-traumatic stress disorder (PTSD).

RESULTS

The pattern of refusal varied among the five subjects. All subjects originated from former Soviet republics, indicating a possible cultural factor. Mean period of inpatient treatment was 5 months. All subjects received intense nursing and were treated with nasogastric tube feeding. Parents were involved and were given support and instructions. All subjects gradually improved after receiving permanent residency permits. Depression and PTSD were co-morbid states. At follow-up, 1-8 years after discharge, all subjects were recovered.

CONCLUSION

Although a severe condition, our five cases suggest a good prognosis for PRS among asylum-seeking children and adolescents.

Patterns of endogenous steroids in apathetic refugee children are compatible with long-term stress

Background

During the last few years, a number of children of asylum applicants in Sweden developed an apathetic or unconscious state. The syndrome was perceived as new, and various explanations were advanced such as factitious disorder, intoxication, or stress. Considering a potential association between traumatic stress and regulation of steroids biosynthesis, this study explored whether changes in concentrations of endogenous steroids were associated with the above syndrome.

Methods

Eleven children were recruited in the study. Concentrations of steroids in blood samples were determined using high sensitivity liquid chromatography tandem mass spectrometry methods. Symptoms were assessed with a clinical rating scale developed for the study. Steroid concentrations were measured at the entry into study and after recovery; and concentrations were evaluated for the association with the symptoms in apathetic children.

Results

Cortisol and cortisone concentrations at baseline were negatively associated with duration of the symptoms from entry into the study to clinical recovery. Higher concentrations of pregnanes (pregnenolone, 17-OH-pregnenolone, and dehydroepiandrosterone) were observed in the symptomatic state and the concentrations decreased after the recovery.

Conclusions

Pattern of low cortisol concentrations found in apathetic children is consistent with long-term stress. An increase of upstream steroid metabolites (pregnanes) was found to be associated with the symptomatic state.

Neurological disorders in complex humanitarian emergencies and natural disasters

Complex humanitarian emergencies include the relatively acute, severe, and overwhelming health consequences of armed conflict, food scarcity, mass displacement, and political strife. Neurological manifestations of complex humanitarian emergencies are important and underappreciated consequences of emergencies in populations worldwide. This review critically assesses the existing knowledge of the range of neurological disorders that accompany complex humanitarian emergencies and natural disasters in both the acute phase of crisis and the "long shadow" that follows.
