    Abstract Functional neurologic disorder (FND) is a "rule-in" diagnosis, characterized by positive examination signs or semiological features. Similar to other clinical diagnoses, providers should ideally see robustly present features, including if possible the identification of multiple features consistent with FND for the diagnosis to be made with a high degree of certainty. Diagnostic pitfalls need to be guarded against and vary depending on FND symptom subtype and the specific patient presentation. This perspective article aims to review pitfalls based on an FND symptom subtype, as well as discuss differential diagnostic considerations with respect to both neurologic and psychiatric entities.

    Title translation Understanding and explaining functional movement disorders.
    Abstract Functional movement disorders are not uncommon in neurological consultations, hospitals and emergency departments. Although the disorder can usually be recognized clinically, the communication of the diagnosis is often unsatisfactory. Those affected are indirectly accused of a lack of insight or openness but it is often the doctors who fail to formulate a coherent and comprehensible explanation of the underlying disorder. In this review an integrative model for the development of functional movement disorders is presented, which places the motor (and nonmotor) symptoms in a neuroscientific light. In addition, explanations and metaphors are presented that have proven helpful in conveying an understanding of the disorder.

    Abstract Introduction: Somatic symptom disorder (SSD) as introduced by the DSM-5 is characterized by chronic somatic symptoms not fully explained by underlying pathology and accompanied by psychological factors, the diagnostic B-criteria. These cognitive, affective, and behavioral disturbances are related to increased attention to somatic symptoms. However, there is a lack of empirical evidence regarding the association between the B-criteria and high symptom reporting in clinical settings.
    Methods: This 12-year retrospective, cross-sectional, observational study examined 6,491 patients from a German psychosomatic outpatient center. The somatoform subscale of HEALTH-49 was used to evaluate somatic symptom reporting. Excessive health concerns and other potential criteria associated with symptom reporting were determined using the ICD-10-Symptom Rating and other HEALTH-49 subscales.
    Results: Regression analysis revealed that the established B-criteria for SSD were the strongest factors associated with somatic symptom reporting, with a standardized beta-coefficient of β = 0.31 (
    Conclusion: This study provides evidence for the concept of SSD related to specific B-criteria associated with somatic symptom reporting, based on a large patient sample. These results point to an important role of psychological symptomatology in patients with somatic symptoms. The findings also suggest that additional factors contribute to the reporting of somatic symptoms. Our results may inform future diagnostic criteria for SSD.

  10. Article ; Online: Dissociative seizures in the emergency room: room for improvement.

    Abstract Background: Dissociative seizures, also known as functional or psychogenic non-epileptic seizures, account for 11%-27% of all emergency seizure presentations. Misdiagnosis as epileptic seizures is common and leads to ineffective and potentially harmful treatment escalations. We assess the potential for diagnostic improvement at different stages of emergency workup and estimate the utility of benzodiazepines.
    Methods: A retrospective study of all emergency presentations with a discharge diagnosis of acute dissociative seizures seen at a university hospital 2010-2022 was performed to assess clinical characteristics and emergency decision-making.
    Results: Among 156 patients (73% female, median 29 years), 15% presented more than once for a total of 203 presentations. Half of seizures were ongoing at first medical contact; prolonged seizures and clusters were common (23% and 24%). Diagnostic accuracy differed between on-site emergency physicians and emergency department neurologists (12% vs 52%). Typical features such as eye closure, discontinuous course and asynchronous movements were common. Benzodiazepines were given in two-thirds of ongoing seizures, often in high doses and preferentially for major hyperkinetic semiology. Clinical response to benzodiazepines was mixed, with a minority of patients remaining either unaffected (16%) or becoming critically sedated (13%). A quarter of patients given benzodiazepines by emergency medical services were admitted to a monitoring unit, 9% were intubated.
    Conclusions: Improved semiological assessment could reduce early misdiagnosis of dissociative seizures. Although some seizures seem to respond to benzodiazepines, critical sedation is common, and further studies are needed to assess the therapeutic ratio.
