Psychiatric aspects of self-induced epileptic seizures

Abstract

Objective: To review the literature on self-induced epileptic seizures and apply psychiatric knowledge to define possible causes and treatment recommendations.

Methods: A review of MEDLINE literature on self-induced epileptic seizures was conducted, followed by cross-referencing with the relevant neurologic, psychiatric and paediatric books and journals.

Results: The reported prevalence of self-induction varies depending on the setting. In most instances, self-inducers are people affected by photosensitive primary generalized epilepsy, in whom self-induction is by intermittent photic stimulation or, more rarely, pattern stimulation or eye closure. Self-induced seizures are most commonly absences with spike-wave, though eyelid myoclonia and generalized myoclonic jerks occur. Earlier studies indicate that the majority of self-inducers were of subnormal intelligence but more recent ones indicate that as a group they could not be considered mentally retarded. Monitoring in a well-lit environment is indicated in any therapy-resistant photosensitive patient to determine whether or not selfinduction occurs. Self-induced epilepsy is notoriously resistant to therapy and reasons for this resistance are discussed. An explanatory model for the initiation and maintenance of selfinduction behaviour is also included.

Conclusions: It is difficult to determine from published papers just what level of clinical difficulty self-induction of seizures actually posed to the patients and clinicians. In some cases there is contradictory evidence as to the degree of willfulness or self-induction. Self-induced epileptic seizures may be an important aspect of poor seizure control in a subgroup of epilepsy sufferers. These seizures might be modifiable by psychiatric intervention or behavioural modification.
