Epilepsy & gambling: Risk factors for problem gambling behaviors in people with epilepsy

OBJECTIVE

Problem gambling results from the complex interaction of neurological factors with psychological, demographic, and socioeconomical influences. The vulnerabilities of people with epilepsy to many of these influences may increase their susceptibility to developing problematic gambling behaviors. The aim of this study was to establish the frequency of gambling participation and the clinical correlates of problem gambling behaviors in people with epilepsy.

METHODS

Lifestyle questions, including the Lie/Bet screening questionnaire were administered to 250 consecutive attendees at a neurology clinic. Valid data were available for 174 adults with epilepsy and 65 adults with other neurological conditions.

RESULTS

With the exception of people with frontal lobe epilepsy (FLE), gambling participation rates in people with epilepsy and those with other neurological conditions were lower than those reported in the general population. While the overall levels of gambling participation were relatively low in this sample, the number of gamblers who responded positively to the lie/bet questionnaire was ten times higher than that seen in the general population, with one in three gamblers in our series reporting signs of escalation. All had epilepsy and were more likely to be taking Levetiracetam or Brivaracetam than the other gamblers in our series. While epilepsy classification was not related to gambling escalation, patients with FLE were overrepresented in this group due to their significantly higher baseline levels of participation in gambling.

CONCLUSIONS

People with FLE may have a heightened vulnerability to developing problem gambling behaviors. The role of the neurological consultation in managing these risks is discussed.
