Abstract

BACKGROUND:

Partial seizures often develop during the clinical course of infantile spasms. Herein, we report a boy with cryptogenic West syndrome, who developed partial seizures that we suspected were induced by the ACTH therapy.

SUBJECT:

The patient developed cryptogenic West syndrome at six months of age and ACTH therapy was started. On the tenth day of treatment, he developed frequent partial seizures, characterized by being motionless during the seizure with eye deviation to the right. The partial seizures stopped after the ACTH was discontinued, although oral carbamazepine was commenced at the same time. Thus, a definitive role for carbamazepine in the treatment of the partial seizures was unclear as the timing of the seizure cessation also corresponded to the discontinuation of the ACTH therapy. We suspected that the partial seizures were induced by the ACTH therapy for the following reasons: (1) seizures appeared only during ACTH therapy, (2) no new epileptic focus was revealed by EEG, MRI, or (99m)TcECD SPECT, and (3) the seizures were different from the epileptic spasms.

CONCLUSION:

Our results suggest that ACTH might induce partial seizures in West syndrome. Further studies are required to confirm this phenomenon.
