Abstract
Cognitive problems represent one of the most common symptom dimensions in functional neurological disorder (FND; >80% of patients) and are frequently associated with distress, disability, and difficulties engaging in evidence-based treatments such as psychotherapy. Cognitive difficulties occur across the FND subtypes (eg, seizures, movement disorders, dizziness) but are largely underrecognized and undertreated by healthcare providers. That is, although a variety of interventions are available for primary functional symptoms and mental health comorbidities, there have not been any systematic efforts to date to specifically target cognitive functioning in FND, leaving an important gap in the literature.Cognitive rehabilitation is a flexible approach utilizing diverse techniques aimed at improving cognition and enhancing functional independence in people with neuropsychiatric disorders. Cognitive rehabilitation can have positive impacts (moderate effect sizes) on cognition and everyday functioning across a variety of conditions, including traumatic brain injury, mild cognitive impairment, long COVID, PTSD, and others. Given the transdiagnostic clinical utility of cognitive rehabilitation, it has potential for benefit in many patients with FND if adapted and applied appropriately.In this review, we highlight the utility of cognitive rehabilitation for FND, with a focus on clinically actionable advice and guidance. We describe fundamental principles of cognitive rehabilitation, evidence for its efficacy and effectiveness across neuropsychiatric disorders, and methods for avoiding potential pitfalls when applying it in FND. We then discuss a Case Vignette in order to emphasize the application of cognitive rehabilitation principles in an individual patient. We conclude with future directions for research and clinical care.
