“…As was the case for the patient of Levy and Jankovic ( 1983 ) the patients never produced frustrated reactions and never attempted self-correction. For De Letter et al ( 2012 ) the fluctuating language problems and neurological symptoms were the primary reasons for considering the speech/language problems of their patients as psychogenic, although they demonstrated organic anomalies. They argue that “the presence of a language disorder in patients with organic cerebral disease cannot demonstrate causation (e.g., Whitlock, 1967 )” (p. 876).…”

“…naming error. De Letter et al ( 2012 ) reported three cases with (non-fluent) agrammatism, overgeneralizations, and paraphasias which could not be attributed to an underlying organic cerebral pathology. All three patients presented with psychiatric conditions: case 1 suffered from bipolar disorder, case 2 had a “manipulative personality” (p. 877), and case 3 had quite an extensive psychiatric history marked by mood swings, depression, and aggressiveness.…”

In the majority of cases published between 1907 and 2014, FAS is due to a neurogenic etiology. Only a few reports about FAS with an assumed psychogenic origin have been published. The present article discusses the findings of a careful database search on psychogenic FAS. This review may be particularly relevant as it is the first to analyze the salient features of psychogenic FAS cases to date. This article hopes to pave the way for the view that psychogenic FAS is a cognate of neurogenic FAS. It is felt that this variant of FAS may have been underreported, as most of the psychogenic cases have been published after the turn of the century. This review may improve the diagnosis of the syndrome in clinical practice and highlights the importance of recognizing psychogenic FAS as an independent taxonomic entity.

“…De Letter et al . (: 869) suggest that one difficulty in this area is the ‘dramatic under‐reporting’ of functional language disorders. This was evident in our review in that many papers simply mentioned these symptoms with little attached detail.…”

“…This means that functional communication and swallowing disorders may go underdiagnosed and consequently under-reported. Currently, functional communication and swallowing disorders are a diagnosis of exclusion (De Letter et al 2012, Teodoro et al 2018, Kim et al 2018. Further research is needed to validate a set of positive diagnostic criteria for SLTs to use both within clinical and research practice.…”

Background Functional neurological disorder (FND) is common across healthcare settings. The Diagnostic and Statistical Manual of Mental Disorders states that speech and swallowing symptoms can be present in FND. Despite this, there is a dearth of guidelines for speech and language therapists (SLTs) for this client group. Aims To address the following question in order to identify gaps for further research: What is known about speech, language and swallowing symptoms in patients with FND? Methods & Procedures A scoping review was conducted. Six healthcare databases were searched for relevant literature: CINAHL PLUS, MEDLINE, ProQuest Nursing and Allied Health Professionals, Science Citation Index, Scopus, and PsychINFO. The following symptoms were excluded from the review: dysphonia, globus pharyngeus, dysfluency, foreign accent syndrome and oesophageal dysphagia. Main Contribution A total of 63 papers were included in the final review; they ranged in date from 1953 to 2018. Case studies were the most frequent research method (n = 23, 37%). ‘Psychogenic’ was the term used most frequently (n = 24, 38%), followed by ‘functional’ (n = 21, 33%). Speech symptoms were reported most frequently (n = 41, 65%), followed by language impairments (n = 35, 56%) and dysphagia (n = 13, 21%). Only 11 publications comment on the involvement of SLTs. Eight papers report direct speech and language therapy input; however, none studied the effectiveness of speech and language therapy. Conclusions & Implications Speech, language and swallowing symptoms do occur in patients with FND, yet it is a highly under‐researched area. Further research is required to create a set of positive diagnostic criteria, gather accurate data on numbers of patients with FND and speech, language or swallowing symptoms, and to evaluate the effectiveness of direct speech and language therapy involvement.
