Priority 9 from the Epilepsy (Canada) PSP

UNCERTAINTY: Aside from anti-seizure drugs and some brain lesions, what causes behavioural changes in people who experience seizures? What is the best way to treat behavioural issues? (JLA PSP Priority 9)
Overall ranking 9
JLA question ID 0110/9
Explanatory note Behavioural changes, such as depression, anxiety, impulsiveness, aggression, and attentional difficulties are often seen in people with epilepsy. Some of these changes may be due to side effects of anti-seizure drugs (ASDs), some may be caused by structural abnormalities in the brain, and some may be caused by seizures themselves. In addition, there may be other contributing factors, such as stress, environment, sleep quality or social settings. More research is needed to determine how each of these affect cognition and behaviour. Current treatments include counselling or psychotherapy, modifying or changing ASDs, or adding medication to treat behavioural issues. Researchers are still trying to determine the most effective treatments or therapies to manage behavioural changes in people with epilepsy. Another key question is how to effectively treat seizures while minimizing or managing behavioural changes.

Original uncertainty examples Behavioural issues: Why is there such a high rate in epilepsy? Differentiate between behaviour and seizures? ~ Are my child's behavioural issues part of a larger syndrome that relates to the epilepsy? -Will my child ever develop enough to 'catch up' to peers in terms of abilities? ~ Can epilepsy cause behavioural changes, depression, or increased anxiety? Can epilepsy affect learning capabilities? ~ What is the latest evidence about the treatment strategies of depression, anxiety, and behavioural problems for people with epilepsy?
