Functional Neurological Disorder (FND) is one of the commonest reasons that people seek help from a neurologist and is for many people a life-long cause of disability and impaired quality of life. Although the evidence base regarding FND pathophysiology, treatment and service development of has grown substantially in recent years, a persistent ambivalence remains amongst health professionals and others as to the veracity of symptoms in those with FND, and whether they are not, in the end, just the same as feigned or malingered symptoms. Here, we provide our perspective on the range of evidence available which in our view provides a clear separation between FND and feigning and malingering. We hope this will provide a further important step forward in the clinical and academic approach to people with FND, leading to improved attitudes, knowledge, treatments, care pathways and outcomes.
