If we're talking about non-epilectic seizures or pseudoseizures, there has been some work done on applying CBT to the problem:

Abstract: Evaluated in an open trial the effectiveness of cognitive behavioral therapy as a treatment of adults with dissociative seizures (i.e., "pseudoseizures"). Although suggestions have been made concerning the management of patients with dissociative seizures, no studies have previously evaluated the systematic use of cognitive behavioral therapy in the treatment of this disorder. Twenty patients diagnosed with dissociative seizures were offered treatment comprising 12 sessions of cognitive behavioral therapy. Principal outcome measures were dissociative seizure frequency and psychosocial functioning, including improvement in employment status and mood. Measures were administered before treatment, at the end of treatment, and at a 6-month follow-up. Treatment was completed by 16 patients (questionnaire measures were not available for 4 patients who discontinued treatment). Following treatment, there was a highly significant reduction in seizure frequency and an improvement in self-rated psychosocial functioning. These improvements were maintained at the 6-month follow-up. There was also a tendency for patients to have improved their employment status between the start of treatment and the 6-month follow-up period.
