Emerging Biomarkers in Functional Neurological Disorders: A Synthesis of Current Research
Functional neurological disorders (FNDs) present a diagnostic challenge due to the absence of definitive biomarkers. This synthesis of current research explores the potential biomarkers for FNDs, aiming to enhance diagnostic accuracy and treatment efficacy. Cortisol levels have been investigated as state, trait, and prognostic biomarkers, reflecting the stress response and potential chronic alterations in hypothalamic-pituitary-adrenal axis functioning in FND patients[1]. Whole-body cryostimulation (WBC) has been proposed as an adjuvant treatment, with a case report demonstrating improvements in body composition, hematological biomarkers, and physical performance, suggesting physiological responses to WBC as potential biomarkers for treatment efficacy[2]. Vitamin B12 deficiency, often resulting from nitrous oxide misuse, has been identified as a consistent feature in hospital admissions for neurological disorders, indicating the importance of metabolic biomarkers in patient management[3]. Functional near-infrared spectroscopy (fNIRS) has been utilized to derive objective hemodynamic biomarkers, with machine learning algorithms demonstrating high accuracy in classifying neuropsychiatric disorders, underscoring the potential of fNIRS in the objective diagnosis of FNDs[4]. Additionally, glutamatergic dysfunction, neuroplasticity, and redox status in peripheral blood have been explored as potential biomarkers for motor conversion disorders, a subtype of FNDs[5]. This body of research signifies a shift towards identifying unfeignable biomarkers that could unravel the complex etiology of FNDs and guide more targeted interventions[6][7].

Salivary biomarkers in Post-concussion syndrome
Traumatic brain injuries (TBIs), particularly mild TBIs, present a complex diagnostic challenge due to their subtle manifestations and the broad spectrum of potential long-term consequences, including post-concussion syndrome (PCS) and chronic traumatic encephalopathy (CTE). The search for reliable diagnostic markers has led to the exploration of salivary biomarkers as a non-invasive, cost-effective means of detecting TBIs and assessing their severity. This review examines the role of salivary biomarkers—S100B, Neurofilament Light Chain (NfL), microRNAs (miRNAs), and Extracellular Vesicles (EVs)—in the diagnosis of TBIs and PCS. Elevated levels of S100B are associated with brain damage, suggesting its potential as an indicator of TBI. NfL, a marker of axonal injury, offers insights into the severity of neural damage. Altered miRNA profiles in saliva can reflect changes in gene expression related to neural injury, providing a molecular signature of TBI and PCS. Furthermore, EVs carry a cargo reflective of cellular and molecular changes post-injury, serving as a promising diagnostic tool. This review highlights the emerging significance of these salivary biomarkers in the early detection and management of TBIs, underscoring the need for further research to validate their clinical utility and integrate them into standard diagnostic protocols.
