Associations between memory loss and trauma in US asylum seekers: A retrospective review of medico-legal affidavits

Head Injury and Associated Sequelae in Individuals Seeking Asylum in the United States: A Retrospective Mixed-Methods Review of Medico-Legal Affidavits

People seeking asylum are susceptible to head injury (HI) due to exposure to various forms of violence including war, torture, or interpersonal violence. Yet, the extents to which clinicians assess HI, and if so, what the associated characteristics are, are not well known. We analyzed 200 U.S.-based medico-legal affidavits using descriptive, multivariate regression, and thematic analysis. Head injury was documented in 38% of affidavits. Those who experienced physical violence were eight times likelier to experience HI than those who did not experience physical violence. Five themes emerged: (1) HI occurred commonly in the context of interpersonal violence (44%), followed by militarized violence (33%); (2) mechanisms of HI included direct blows to the head and asphyxiation, suggesting potential for both traumatic brain injury and brain injury from oxygen deprivation; (3) HI was often recurrent and concurrent with other physical injuries; (4) co-morbid psychiatric and post-concussive symptoms made it challenging to assess neurological and psychiatric etiologies; and (5) overall, there was a paucity of assessments and documentation of HI and sequelae. Among individuals assessed for asylum claims, HI is common, often recurrent, occurring in the context of interpersonal violence, and concurrent with psychological and other physical trauma. Physical violence is an important risk factor for HI, which should be assessed when physical violence is reported.

Clinician perspectives on characteristics and care of traumatic brain injury among asylum seekers and refugees

PURPOSE

Traumatic brain injury (TBI) disproportionately affects asylum-seekers and refugees (ASR), although underdiagnosed and undertreated. Our study assesses clinicians' perspectives on characteristics and management of TBI among ASR, with the hope of improving TBI management in this population.

MATERIALS AND METHODS

We conducted six focus groups of 16 clinicians across two academic medical centers in Boston, Massachusetts, United States. Clinicians in our sample included primary care clinicians, nurse practitioners, social workers, psychologists, neurologists, psychiatrists, and neuropsychologists. We analyzed the qualitative data following a hybrid inductive-deductive thematic analytic approach.

RESULTS

Clinicians characterized TBI among ASR as mostly mild and remote, involving head strikes, perpetrated predominantly by interpersonal violence and strangulation-related brain injury, and involving symptom overlap with mental health diagnoses, challenging diagnosis. Clinicians also described inadequate screening, the importance of connecting the physical and psychological symptoms of the brain injury rather than viewing them as distinct, and addressing diagnosis-related stigma and shame. Finally, they discussed lack of TBI-specific knowledge among providers and patients alike, and resource limitations affecting the continuum of care for this population.

CONCLUSION

Integrating clinicians' perspectives in caring for this population allows us to best meet their needs, including in TBI recovery.

Asylum seekers and the role of the acute care physician

There has been a recent influx of migrants and asylum seekers to the United States. They often arrive with poor social support and an inability to access reliable health care. This can lead to overutilization of emergency departments (ED) while awaiting legal proceedings. With asylum seekers in all 50 states, it is important for emergency physicians (EP) to understand the barriers to care and difficulties asylum seekers face, and to gain tools to improve both migrants' and community health. Migration and experiences within the United States can worsen pre-existing health conditions. EPs are uniquely positioned to screen for acute pathology and link people to care. Psychiatric illnesses may present differently in asylum seekers. EPs must understand the sequalae of trauma to address it. EPs must also be aware of legal protections for asylum seekers to care for these patients, and recognize challenges faced by the population to mitigate health disparities.

Neurological Care of Refugees and Other Forcibly Displaced Persons

There are more than 100 million forcibly displaced persons (FDPs) in the world today, including a high number of people who experience neurologic symptoms and presentations. This review summarizes the conceptual frameworks for understanding neurological health risks and conditions across the migration journey (premigration, migration journey, and postmigration) and life span, including special attention to pediatric FDPs. The interaction with psychiatric illness is discussed, as well as the available published data on neurologic presentations in FDPs in the medical literature. A social determinant of health lens is used to provide ways in which forcible displacement can influence brain health and neurological outcomes. Priorities and future needs for the neurological care of refugees and other FDPs are suggested.

Medical evidence in asylum applications: Medical versus legal approaches

The purpose of this narrative review is to elucidate the ways the clinicians working on forensic medical evaluations can engage with asylum proceedings. We compare the legal and medical perspectives on different aspects of forensic medical evidence, asylum evaluations, and asylum applications. As asylum seekers must demonstrate a well-founded fear of persecution in order to receive asylee status, legal and medical professionals often need to collaborate in asylum cases. Although significant evidence has demonstrated that an objective expert medical opinion can support asylum claims, few studies have analyzed how the medical professional's role complements or is at odds with the goals of the legal system. This review summarizes and compares key aspects of the medical and legal perspectives on trauma, credibility, autobiographical memory, and medical evidence to better comprehend the role that medical professionals can play in writing medical affidavits for asylum applications. We dissect legal misconceptions surrounding trauma and the consequences of such misunderstandings and make recommendations for medical evaluators who are working in a forensic capacity.

Head Trauma in Refugees and Asylum Seekers: A Systematic Review

BACKGROUND AND OBJECTIVES

Refugees and asylum seekers are at risk of head trauma. They endure blows to the head due to exigent circumstances necessitating resettlement (e.g., torture, war, interpersonal violence) and during their dangerous journeys to refuge. Our objective was to assess the global prevalence of head trauma in refugees and asylum seekers and describe its clinical characteristics in this population.

METHODS

The protocol was registered in the PROSPERO International Prospective Register of Systematic Reviews (CRD42020173534). PubMed/MEDLINE, PsycInfo, Web of Science, Embase, and Google Scholar databases were searched for relevant studies. We included all studies in English that comprised refugees or asylum seekers of any age and examined the prevalence or characteristics of head trauma. We excluded studies that were not peer-reviewed original research. Information was recorded on the prevalence of head trauma, method of ascertaining head trauma, severity, mechanism of injury, other trauma exposures, and comorbidities. Descriptive analyses and narrative syntheses were performed.

RESULTS

A total of 22 studies were included, of which 13 with 6,038 refugees and asylum seekers reported head trauma prevalence. Prevalence estimates ranged from 9% to 78%. Heterogeneity among studies precluded meta-analysis. Most studies were US based (n = 9, 41%), followed by the Middle East (n = 5, 23%). Most refugees or asylum seekers were from the Middle East (n = 9, 41%), with those from Latin America least represented (n = 3, 14%). Studies disproportionately involved younger (pooled mean age = 29 years) adult samples composed of men. Recruitment settings were predominantly hospitals/clinics (n = 14, 64%), followed by refugee camps (n = 3, 14%). The most common mechanism of injury was direct impact through a beating or blow to the head. Studies varied greatly in how head trauma was defined and ascertained; no study used a validated traumatic brain injury (TBI)-specific screening tool. Similarly, TBI severity was not uniformly assessed, although hospital-based samples captured more moderate-to-severe head injuries. Mental health comorbidities were more frequently documented rather than physical health ones. Only 2 studies included a comparison with local populations.

DISCUSSION

Refugees and asylum seekers are vulnerable to head trauma, but studies using systematic approaches to screening are lacking. Increased attention to head trauma in displaced populations will allow for optimizing equitable care for this growing vulnerable population.

The Presence and Profile of Neurological Conditions and Associated Psychiatric Comorbidities in U.S. Resettled Refugees: A Retrospective Single Center Study

Refugees are a vulnerable, growing population who confront a myriad of traumas leading to their forced migration. Although psychiatric illnesses of resettled refugees are well-documented, there is a paucity of studies characterizing their neurological disease profiles. This study aimed to characterize the frequency and range of neurological disorders in a sample of resettled refugees receiving care at a community health center in Massachusetts, U.S.A. We performed a retrospective medical record review of adult (≥ 18 years) resettled refugees between May 2001 and December 2012 at a community health center in Northeast Massachusetts. Sociodemographic and clinical characteristics pertaining to neuropsychiatric health were collected from medical records using a standardized data extraction tool. Group comparisons between those with and without neurological illness and associated sociodemographic and psychiatric characteristics were evaluated using χ² and independent samples two-tailed t-tests. In our sample (n = 779), 53.3% (n = 415) were male and 48.8% (n = 380) were from the African continent. The mean age was 33.2 ± 12.4 years (range 18-85). 36.8% were diagnosed with at least one neurological disorder and 18.1% with more than one neurological illness. The most common diagnoses were headaches (28.3%), sleep disorders (11.2%), cognitive impairment/ dementia (5.5%), and head trauma (5.5%). Exploratory analyses revealed that participants with neurological illness were more likely to be older (p < .001), female (p = .002), and diagnosed with co-morbid psychiatric diagnoses (p < .001) than those without neurological illness. Neurological disorders frequently co-occur with psychiatric comorbidities among U.S. resettled adult refugees. Standard refugee health assessments should incorporate screening and treatment for neurological illnesses.

The Gory Details: Asylum, Sexual Assault, and Traumatic Memory

For asylum seekers to be granted asylum, they must convince immigration officials that they have been persecuted or that they fear they will be persecuted if returned to their home country. This article discusses the reluctance of asylum seekers to be forthcoming about sexual assault as a form of persecution and the ways in which traumatic memory can affect narratives of persecution for rape survivors. Many asylum seekers, particularly those who have been sexually assaulted, show symptoms consistent with trauma survivors. Consequently, their narratives of persecution are often shaped by partial and incomplete memory recall. The result is that how asylum seekers who have been sexually assaulted tell their stories of persecution is the antithesis of the expectations of credibility. This article is based on qualitative research in Los Angeles, California, and New York City, New York, in the United States. It includes interviews with asylum seekers, immigration attorneys, immigrant service providers, asylum officers, and immigration judges; observations of immigration court hearings; and content analysis of asylum applications. I use these sources to argue that the harm of rape and its long-lasting effects evidenced by symptoms of traumatic memory impacts how asylum seekers articulate stories of persecution. How these stories are told can have devastating effects for asylum seekers that may jeopardize their ability to gain asylum if immigration officials do not view them as credible applicants.

Torture Survivors and Asylum: Legal, Medical, and Psychological Perspectives

Torture occurs worldwide. Survivors seeking asylum are detained and must complete a complicated legal process to prove a "well-founded fear of persecution" if returned to their home countries. Forensic evaluations guided by the United Nations Istanbul Protocol increase asylum grant rates. Medical evaluation emphasizes skin examination, which can provide strong evidence of torture. Female genital mutilation and cutting, a basis for asylum, is classified according to the World Health Organization. Many resettled refugees and foreign-born immigrants at urban health care facilities have been tortured, but few report it to physicians due to factors affecting both survivors and physicians. Specific torture methods can cause characteristic long-term sequelae. Painful somatic disorders of mind-body interaction and psychological disorders are common. Practices derived from cultural factors and traumatized individuals' feedback enhance management of survivors. Individual and group psychotherapy provide modest proven benefit, but assessment is limited. Physicians and psychotherapists should coordinate care.

Impact of forensic medical evaluations on immigration relief grant rates and correlates of outcomes in the United States

The purpose of this study was to investigate the impact of forensic medical evaluations on grant rates for applicants seeking immigration relief in the United States (U.S.) and to identify significant correlates of grant success. We conducted a retrospective analysis of 2584 cases initiated by Physicians for Human Rights between 2008 and 2018 that included forensic medical evaluations, and found that 81.6% of applicants for various forms of immigration relief were granted relief, as compared to the national asylum grant rate of 42.4%. Among the study's cohort, the majority (73.7%) of positive outcomes were grants of asylum. A multivariable regression analysis revealed that age, continent of origin, history of sexual or gender-based violence, gang violence, LGB sexual orientation, and being detained by the U.S. government at the time of evaluation request were statistically associated with case outcomes. Forensic physical evaluation was more strongly associated with a positive outcome than forensic psychological evaluation. Our findings strengthen and expand prior evidence that forensic medical evaluations can have a substantial positive impact on an applicant's immigration relief claim. Given the growing applicant pool in the U.S., there is an urgent need for more trained clinicians to conduct forensic medical evaluations as well as to educate adjudicators, immigration lawyers, and policy makers about the traumatic nature of the life-altering events that applicants for immigration relief experience.
