Functional neurological disorder (FND) is a condition where neurological symptoms arise from functional, rather than structural, brain issues. Sitting at the crossroads of neurology and psychiatry, FND reflects complex interactions between biological, psychological, and social factors. Psychotherapy, particularly cognitive behavioural therapy, plays a crucial role in addressing symptoms, enhancing emotional regulation, and improving quality of life. Emerging treatments, technological innovations, and personalised approaches are reshaping care, aiming to overcome stigma and deliver more accessible, tailored interventions. Ongoing research continues to refine strategies for managing this often-misunderstood disorder.
