Abstract
PURPOSE OF REVIEW: Neurologic symptoms due to a psychogenic cause are frequently seen in clinical practice. Psychogenic nonepileptic seizures (PNES) and psychogenic movement disorders (PMD) are among the most common psychogenic neurologic disorders. PNES and PMD are usually investigated and managed separately by different neurology subspecialists. We review the main epidemiologic and clinical features of both PNES and PMD, aiming to highlight their similarities and differences and to see whether a common framework for these disorders exists. RECENT FINDINGS: Data from the literature show that there is a profound overlap between PNES and PMD, which would argue for a larger unifying pathophysiology with variable phenotypic manifestations. SUMMARY: Collaborative and integrated research among epileptologists, movement disorders experts, psychiatrists, psychologists, and physiotherapists may increase our collective knowledge about the pathophysiologic mechanisms of PNES and PMD and therefore improve outcomes for these patients.
