he diagnosis of Functional Neurological Disorder (FND) represents a challenging but critical endeavor in neurology and psychiatry, requiring an integrated approach that transcends traditional diagnostic categories. This paper outlines a comprehensive framework for diagnosing FND, emphasizing the importance of direct clinical assessment, the strategic exclusion of other neurological and medical conditions, and the identification of characteristic positive signs. Contrary to being a diagnosis of exclusion, FND involves specific, identifiable signs such as Hoover’s sign, distractibility, and other non-physiological findings. These markers facilitate a positive diagnostic outcome, reinforcing that FND symptoms are genuine and rooted in functional impairments rather than structural abnormalities. Furthermore, the method of communicating the diagnosis to patients significantly affects their understanding, acceptance, and engagement in subsequent treatment, which can include physical therapy, psychotherapy, and medication. By providing a clear diagnostic pathway that incorporates both neurologic and psychiatric expertise, this paper aims to enhance the accuracy of FND diagnoses and improve patient outcomes through tailored, multidisciplinary care.
