Abstract

Highlights: Suggestive seizure induction (SSI) is an accurate diagnostic screening tool. The overall level of evidence is low. Various techniques of suggestions have high diagnostic yields. There are some risks and side effects of SSI. There are no known relevant predictive factors of successful SSI. Abstract: Suggestive seizure induction is a widely used method for diagnosing psychogenic nonepileptic seizures (PNES). Despite seven decades of multidisciplinary research, however, there is still no unified protocol, no definitive agreement on the ethical framework and no consensus on diagnostic utility. This systematic review surveys the evidence at hand and addresses clinically relevant aspects of suggestive seizure induction. In addition to its use for facilitating the diagnostic process, its mechanism of action and utility in elucidating the psychopathology of PNES will be discussed.
