Many patients with epilepsy have warning symptoms prior to seizure onset, and some of these individuals report the ability to abort or prevent these seizures. We investigated the clinical characteristics of perceived self-control of seizures in 174 patients with uncontrolled partial epilepsy. The warning symptoms were categorized as premonitory (prodrome) and as initial symptoms of simple partial seizure onset, depending on the relationship between the warning events and the ensuing seizures. About 50% of the patients with simple partial seizure onset and about 70% of those with prodrome or premonitory symptoms reported that they could abort or prevent their seizures by various self-developed techniques. Patients who attempted to abort or prevent their seizures reported success rates as high as 80%. The proportion of patients with secondary generalized seizures was significantly lower in patients who tried to abort their seizures than in those who did not (p<0.05). The ability to prevent seizures was significantly higher in patients with brain lesions on MRI than in those without lesions (p<0.05). These results suggest that spontaneously developed methods are helpful in controlling seizures in some patients with uncontrolled partial epilepsy and that the potential success of self-control methods may be influenced by structural abnormalities on brain MRI.
