Functional Neurological Disorders (FND) are characterized by neurological symptoms that are not explained by identifiable neurological disease. The diagnosis of FND is complex and requires a careful approach to avoid misdiagnosis, which can have significant legal and ethical implications. Misdiagnosis can lead to unnecessary treatments, psychological harm, and a lack of informed consent. Studies have shown that misdiagnosis rates for FND are similar to those for ‘organic’ neurological diseases, and the misdiagnosis of neurological diseases as FND occurs at a similar frequency. The challenge is compounded when patients have comorbid conditions, such as multiple sclerosis, where both conditions need to be treated. Ethical concerns include the potential for stigmatization of patients, the responsibility of healthcare professionals to correct public misinformation, and the importance of accurate communication of diagnoses. Legal concerns revolve around the accuracy of diagnosis, informed consent, and confidentiality. To address these concerns, enhanced training for healthcare providers, development of guidelines for media engagement, and multidisciplinary approaches to assessment and treatment are recommended. The goal is to ensure that patients receive accurate diagnoses and appropriate care, while healthcare providers navigate the ethical and legal landscape with due diligence.
