Summary: In this study, differences in white matter integrity were observed between FND patients and healthy controls, with specific brain regions showing correlations with symptom severity, physical disability, and illness duration. These findings provide valuable insights into the neurocircuit pathways involved in the pathophysiology of FND, particularly related to salience, defensive behaviors, and emotion regulation.

Summary: This study found that patients with FND exhibit higher suggestibility than controls on standardised behavioural scales and are more responsive to suggestive symptom induction. These results suggest that atypical suggestibility may be a risk factor for FND and could potentially aid in diagnosis and treatment.

Summary: This study explores the relationship between speech disorder-stuttering and epileptic seizures, and raises awareness of the diagnostic dilemmas and potential misdiagnosis. It emphasizes the complexity and importance of accurately detecting stuttering-induced epilepsy.

Summary: Functional neurologic (conversion) disorder is a neuropsychiatric condition that represents the intersection of psychiatry and neurology. Advancements in rule-in diagnostic approaches and understanding of psychological factors have improved our knowledge of FND, with emphasis still placed on the importance of emotions in the conceptual understanding of this disorder.

Summary: Functional neurological disorder (FND) is often misdiagnosed, leading to higher healthcare costs. This study analyzed the direct costs associated with FND diagnosis compared to other neurological disorders, and explored cost trends related to clinical and demographic features of FND.

Summary: This study provided a population-based estimate of the prevalence of PNES for the first time. The findings suggest that the prevalence of PNES falls within the range of estimates from non-population-based data. A notably high prevalence of PNES was found in the 15-19-year age group.

Summary: Descriptions of seizure manifestations can aid in identifying patients with dissociative seizures, but no single manifestation is specific for either epileptic seizures or dissociative seizures. Patients with mixed epileptic seizures and dissociative seizures report factors divergent from those with isolated epileptic seizures or dissociative seizures.

Summary: This study aimed to compare the multidimensional psychopathological profiles of patients with PNES and ES. The results showed that PNES patients reported more overall psychopathology, particularly in childhood trauma, dissociation, and depression. These psychopathological profiles have limited usefulness as standalone screening tools for differentiating PNES and ES.

Summary: This review summarizes the recent advances in the diagnosis and treatment of psychogenic nonepileptic seizures (PNES). It emphasizes the effectiveness of psychotherapeutic modalities in empowering patients and reducing seizures, and highlights the importance of a multidisciplinary and holistic approach. The review also suggests the need for additional treatment modalities and further research for patients who are refractory to current treatment.

Summary: This study suggests that ADHD is underrecognized and underdiagnosed in patients presenting to the Epilepsy Monitoring Unit, and screening tools may be useful to help clinicians address seizure comorbidities such as ADHD.

Summary: Adolescents with psychogenic nonepileptic seizures (PNES) face numerous challenges in school. This qualitative study explored the experience of attending school as an adolescent with PNES and identified several themes, including stress, bullying, accusations of faking seizure events, feeling left out, and school management of PNES. The study highlights the need for increased understanding and collaboration among peers, as well as from families, healthcare providers, and school personnel.

Summary: This study investigated the frequency of ictal crying in epileptic seizures (ESs) and psychogenic nonepileptic seizures (PNESs), highlighting the differences between the two. The study also analyzed the etiology, symptoms, treatment options, and prognosis of ictal crying in ESs. Results showed that all patients in the ES group had refractory focal epilepsy, and some achieved good outcomes through surgical treatment.

Summary: This study explored how neurology specialists perceive psychogenic nonepileptic seizures (PNES) through an art project, finding that they often see PNES as masking underlying psychological issues with limited understanding of its origin. Specialists used the symbol of a labyrinth to represent the challenges in diagnosing and providing multidisciplinary care for patients with PNES.

Summary: This study investigated the frequency of epileptic seizures (ES) and psychogenic non-epileptic seizures (PNES) in an epilepsy monitoring unit and driving-related issues in each group. The results showed that although the PNES group had a higher frequency of events, a large percentage of these patients complied with driving law recommendations. Patients with PNES had a higher incidence of habitual events while driving but were less likely to be involved in accidents resulting in serious bodily injury compared to patients with ES.

Summary: The study aimed to differentiate patients with psychogenic nonepileptic attacks (PNEA) from status epilepticus (SE) by analyzing clinical features and laboratory values. Patients intubated for convulsive activity with 5-6 risk factors were more likely to have PNEA, and these simple characteristics could raise clinical suspicion for PNEA in the appropriate setting. Early neurological consultation may help prevent unnecessary intubation of at-risk patients.
