    BackgroundThe prevalence of dissociative seizures is between 2 and 33 sufferers per 100,000 persons. 70% of sufferers are women. Dissociative seizures markedly impair quality of life. Their close superficial resemblance to epileptic seizures makes them hard to diagnose.MethodsSelective literature search in PubMed and PsycINFO.ResultsPersons with dissociative seizures constitute a mixed group with a wide variety of predisposing, precipitating, and maintaining factors. Some 90% have comorbid psychiatric disorders such as depression, anxiety, somatoform disorders, personality disorders, or post-traumatic stress disorder. Video-EEG monitoring enables highly reliable diagnosis. Psychotherapy is considered the treatment of first choice; in prospective studies, it has been found to lower the frequency of dissociative seizures by at least 50%, or to eliminate them completely, in 50% to 80% of patients. An individually tailored combination of behavioral therapeutic, imagery-based, and psychodynamic approaches seems reasonable. For the treatment of psychiatric comorbidities, psychotherapy is indicated, in combination with psychoactive drugs if necessary. Before any treatment is provided, the diagnosis should be communicated to the patient in an appropriate way, ideally by both the neurologist and the psychotherapist, so that the patient can develop an alternative disease model.ConclusionWhen the diagnosis of dissociative seizures has been made, psychotherapy is indicated, possibly in combination with psychoactive medication, in the setting of long-term treatment provided in collaboration by the neurologist, psychiatrist, psychotherapist, and family physician. Further randomized trials are needed to determine which treatments are best for which subgroups of patients.
