Abstract
Sociolinguistic factors such as status and prestige can significantly impact the persistence of an accent in a patient with Foreign Accent Syndrome (FAS). FAS is a rare acquired syndrome that affects a speaker's accent typically caused by a stroke or trauma. In this presented FAS case study, we explore two distinct perspectives on a shift from a Sicilian to a North-East variety of Italian accent, caused by an accident trauma. Data have been collected with an ethnographic approach to explore the patient's narrative towards his 'foreign accent'. Firstly, the study analyzes the perception of native listeners through a speech sample perception test of different varieties of Italian. The listeners' responses revealed a diversified classification of the accent, highlighting the listener's crucial role in assigning the status of 'foreignness' to a particular variety. Additionally, an analysis with Praat software showed that the FAS speaker used a variety with some Sicilian and North-East traits. Secondly, the study investigated the patient's perception of their new accent through an ethnographic approach and participant observer technique. The results revealed a typology of FAS speakers that correlated with sociolinguistic factors not previously identified by research. In conclusion, this study sheds light on the complex interplay between sociolinguistic factors and FAS, demonstrating the importance of exploring FAS under various perspectives of research.

Abstract
Foreign accent syndrome (FAS) is characterized by new onset speech that is perceived as foreign. Available data from acquired cases suggests focal brain damage in language and sensorimotor brain networks, but little remains known about abnormal functional connectivity in idiopathic cases of FAS without structural damage. Here, connectomic analyses were completed on three patients with idiopathic FAS to investigate unique functional connectivity abnormalities underlying accent change for the first time. Machine learning (ML)-based algorithms generated personalized brain connectomes based on a validated parcellation scheme from the Human Connectome Project (HCP). Diffusion tractography was performed on each patient to rule out structural fiber damage to the language system. Resting-state-fMRI was assessed with ML-based software to examine functional connectivity between individual parcellations within language and sensorimotor networks and subcortical structures. Functional connectivity matrices were created and compared against a dataset of 200 healthy subjects to identify abnormally connected parcellations. Three female patients (28-42 years) who presented with accent changes from Australian English to Irish (n = 2) or American English to British English (n = 1) demonstrated fully intact language system structural connectivity. All patients demonstrated functional connectivity anomalies within language and sensorimotor networks in numerous left frontal regions and between subcortical structures in one patient. Few commonalities in functional connectivity anomalies were identified between all three patients, specifically 3 internal-network parcellation pairs. No common inter-network functional connectivity anomalies were identified between all patients. The current study demonstrates specific language, and sensorimotor functional connectivity abnormalities can exist and be quantitatively shown in the absence of structural damage for future study.

Abstract
Foreign accent syndrome (FAS) is a rare, poorly understood speech disorder. It is characterized by the patient speaking their native language in a different accent foreign to both the speaker and the listener. A majority of previously reported cases have been described in patients with diagnosed organic brain damage and a handful of other psychiatric disorders. FAS was not the result of language experience in our index patient, and there is no history of the patient ever visiting the United States of America. This case is presented because it is the first-ever seen case in the environment.

Abstract
OBJECTIVE Explore trauma, stress, and other predictive factors for treatment outcome in conversion disorder/functional neurological disorder (CD/FND). METHODS Prospective observational design. Clinical cohort study among consecutive outpatients with DSM-IV CD/FND in a specialized mental health institution for somatic symptom disorders and related disorders (SSRD), presented between 1 February 2010 and 31 December 2017. Patient files were assessed for early childhood trauma, childhood sexual abuse, current stress, and other predictive factors. Patient-related routine outcome monitoring (PROM) data were evaluated for treatment outcome at physical (Patient Health Questionnaire [PHQ15], Physical Symptoms Questionnaire [PSQ]) level as primary outcome, and depression (Patient Health Questionnaire [PHQ9]), anxiety (General Anxiety Disorder [GAD7]), general functioning (Short Form 36 Health Survey [SF36]), and pain (Brief Pain Inventory [BPI]) as secondary outcome. RESULTS A total of 64 outpatients were included in the study. 70.3% of the sample reported childhood trauma and 64.1% a recent life event. Mean scores of patients proceeding to treatment improved. Sexual abuse in childhood (F(1, 28) = 30.068, β = 0.608 p < .001) was significantly associated with worse physical (PHQ15, PSQ) treatment outcome. 42.2% reported comorbid depression, and this was significantly associated with worse concomitant depressive (PHQ9) (F[1, 39] = 11.526, β = 0.478, p = .002) and anxiety (GAD7) (F[1,34] = 7.950, β = 0.435, p = .008) outcome. CONCLUSION Childhood sexual abuse is significantly associated with poor treatment outcome in CD/FND. Randomized clinical trials evaluating treatment models addressing childhood sexual abuse in CD are needed.

Abstract
OBJECTIVE Foreign accent syndrome (FAS) is widely understood as an unusual consequence of structural neurological damage, but may sometimes represent a functional neurological disorder. This observational study aimed to assess the prevalence and utility of positive features of functional FAS in a large group of individuals reporting FAS. METHODS Participants self-reporting FAS recruited from informal unmoderated online support forums and via professional networks completed an online survey. Speech samples were analysed in a subgroup. RESULTS Forty-nine respondents (24 UK, 23 North America, 2 Australia) reported FAS of mean duration 3 years (range 2 months to 18 years). Common triggers were: migraine/severe headache (15), stroke (12), surgery or injury to mouth or face (6) and seizure (5, including 3 non-epileptic). High levels of comorbidity included migraine (33), irritable bowel syndrome (17), functional neurological disorder (12) and chronic pain (12). Five reported structural lesions on imaging. Author consensus on aetiology divided into, 'probably functional (n=35.71%), 'possibly structural' (n=4.8%) and 'probably structural' (n=10.20%), but positive features of functional FAS were present in all groups. Blinded analysis of speech recordings supplied by 13 respondents correctly categorised 11 (85%) on the basis of probable aetiology (functional vs structural) in agreement with case history assignment. CONCLUSIONS This largest case series to date details the experience of individuals with self-reported FAS. Although conclusions are limited by the recruitment methods, high levels of functional disorder comorbidity, symptom variability and additional linguistic and behavioural features suggest that chronic FAS may in some cases represent a functional neurological disorder, even when a structural lesion is present.

Abstract
We present a case of sudden onset, acquired altered accent in the speech of NL, a 48-year-old, left-handed female. NL's typical Standard Southern British English accent was preserved in singing and reading, but altered in recitation, repetition and spontaneous speech. Neuropsychological investigation, impressionistic and acoustic analysis of accented and unaccented speech are documented. The altered accent displays a slower speech rate and longer duration of consonants and vowels. There is evidence for a shift towards syllable-timed rhythm. NL's altered accent displays atypical coordination between voicing and supra-laryngeal articulation, reduced mean and range of F0, and minor differences in vowel space. These features are broadly consistent with other documented cases of Foreign Accent Syndrome, regardless of aetiology. However, NL's profile of preserved and impaired speech does not fit any pattern typically associated with organic neurological disorder. Moreover, left-handed preference may contribute to differences between singing and reading, versus recitation, repetition and spontaneous speech.

Abstract
Introduction: Foreign accent syndrome (FAS) is a rare speech disorder. It is becoming increasingly common to find reports of cases about alterations different from the suprasegmental aspects of speech, although these reports are not frequent in Spanish-speaking patients.Case presentation: 48-year-old female patient from Colombia diagnosed with FAS, segmental and suprasegmental speech alterations, and changes in cognitive domains (executive functions and language). The woman also presented with motor and affective changes. Brain imaging studies ruled out structural involvement and follow-up at one year did not show significant changes in speech.Discussion: This case presents the neurological, neuropsychological and speech features of a Spanish-speaking patient with FAS. Greater alteration in vowels than in consonants, alteration in pronunciation time, variation in rhythm and intonation of words and phrases, decrease of time between syllables, and insertion of vowels are common elements between this patient and other cases of FAS in non-Spanish speaking subjects.Conclusions: FAS is essentially a speech alteration; however, it can be accompanied by other physical and psychological signs. This case report allows recognizing the essential components for the definition, diagnosis and intervention of this syndrome.

Abstract
Foreign accent syndrome is a rare motor speech disorder that causes patients to speak their language with a non-native accent. In the neurogenic condition, the disorder develops after lesions in the language dominant hemisphere, often affecting Broca's area, the insula, the supplementary motor area and the primary motor cortex. Here, we present two new cases of FAS after posterior fossa lesions. The first case is a 44-year-old, right-handed, Dutch-speaking man who suffered motor speech disturbances and a left hemiplegia after a pontine infarction. Quantified SPECT showed a bilateral hypoperfusion in the inferior lateral prefrontal and medial inferior frontal regions as well as a significant left cerebellar hypoperfusion. Further clinical investigations led to an additional diagnosis of brainstem cognitive affective syndrome which closely relates to Schmahmann's syndrome. The second patient was a 72-year-old right-handed polyglot English man who suffered a stroke in the vascular territory of the left posterior inferior cerebellar artery (PICA) and developed a foreign accent in his mother tongue (English) and in a later learnt language (Dutch). In this paper, we discuss how the occurrence of this peculiar motor speech disorder can be related to a lesion affecting the posterior fossa structures.

Abstract
BACKGROUND Few publications deal with non-neurogenic language disorders (NNLDs), distinct from psychogenic speech disorders such as psychogenic dysphonia or stuttering. NNLDs are alterations in language owing to psychosomatic preoccupations, conversion disorder, psychiatric disorders, or other psychological reasons. OBJECTIVE To identify and classify the range of NNLDs and their characteristics. METHODS This review summarizes the literature on disturbances in language, broadly defined as the use of symbols for communication, which may have a psychogenic or psychiatric etiology. RESULTS The literature suggests a classification for NNLDs that includes psychogenic aphasia with dysgrammatism; psychogenic "lalias" including oxylalia and agitolalia, palilalia and echolalia, xenolalia, glossolalia, and coprolalia; psychologically-mediated word usage; psychotic language; and psychogenic forms of the foreign accent syndrome. CONCLUSIONS Clinicians and researchers have insufficiently emphasized the presence of NNLDs, their characteristics, and their identification. Yet, these disorders may be the first or predominant manifestation of a psychologically-mediated illness. There are 2 steps to recognition. The first is to know how to distinguish NNLDs from the manifestations of neurogenic language impairments after a neurological evaluation. The second step is awareness of specific associated and examination features that suggest the presence of a NNLD.

Abstract
A 57-year-old right-handed man was admitted to our hospital because of right facial paresis and acute-onset dysarthria. He presented with non-fluent aphasia. His aphasia gradually improved, but he started speaking with a strange accent and intonation from the fifth hospital day. He was diagnosed with foreign accent syndrome (FAS), which lasted for 2 months. MRI revealed ischemic infarction with edema in the superior, middle, and inferior parts of the left precentral gyrus. One year later, MRI revealed old, small infarct lesions in the left precentral gyrus, middle frontal gyrus, and postcentral gyrus. We suspected that FAS developed because of disturbance of prosody in the speaking network on improving his aphasia. His meticulous character was probably influenced on developing FAS. The responsible lesions possibly were those in the reversible parts of the left precentral gyrus with edema on acute stage.

Abstract
Foreign accent syndrome (FAS) is a speech disorder that is defined by the emergence of a peculiar manner of articulation and intonation which is perceived as foreign. In most cases of acquired FAS (AFAS) the new accent is secondary to small focal lesions involving components of the bilaterally distributed neural network for speech production. In the past few years FAS has also been described in different psychiatric conditions (conversion disorder, bipolar disorder, and schizophrenia) as well as in developmental disorders (specific language impairment, apraxia of speech). In the present study, two adult males, one with atypical phonetic production and the other one with cluttering, reported having developmental FAS (DFAS) since their adolescence. Perceptual analysis by naïve judges could not confirm the presence of foreign accent, possibly due to the mildness of the speech disorder. However, detailed linguistic analysis provided evidence of prosodic and segmental errors previously reported in AFAS cases. Cognitive testing showed reduced communication in activities of daily living and mild deficits related to psychiatric disorders. Psychiatric evaluation revealed long-lasting internalizing disorders (neuroticism, anxiety, obsessive-compulsive disorder, social phobia, depression, alexithymia, hopelessness, and apathy) in both subjects. Diffusion tensor imaging (DTI) data from each subject with DFAS were compared with data from a group of 21 age- and gender-matched healthy control subjects. Diffusion parameters (MD, AD, and RD) in predefined regions of interest showed changes of white matter microstructure in regions previously related with AFAS and psychiatric disorders. In conclusion, the present findings militate against the possibility that these two subjects have FAS of psychogenic origin. Rather, our findings provide evidence that mild DFAS occurring in the context of subtle, yet persistent, developmental speech disorders may be associated with structural brain anomalies. We suggest that the simultaneous involvement of speech and emotion regulation networks might result from disrupted neural organization during development, or compensatory or maladaptive plasticity. Future studies are required to examine whether the interplay between biological trait-like diathesis (shyness, neuroticism) and the stressful experience of living with mild DFAS lead to the development of internalizing psychiatric disorders.
