The aim of this study is to determine the role of SISCOM (see below) in aiding clinicians to manage epilepsy surgery candidates. SISCOM is already a routine component of pre-surgical epilepsy evaluation at Mayo Clinic. In particular, we are interested in assessing whether use of SISCOM can minimize the need for prolonged (>24 hours) invasive monitoring with electrodes placed on the surface of the brain prior to surgical resection.
Note: this study has recruited the required number of patients and is closed to further enrolment.
|Condition or disease|
Successful epilepsy surgery depends on accurate identification of the area of brain from which seizures originate (the epileptogenic zone). There are many non-invasive tests (including EEG and MRI) to indicate this area. Some patients require implantation of intracranial electrodes in order to determine the epileptogenic zone. A test known as SISCOM (subtraction ictal-interictal SPECT co-registered with MRI) has been validated as a non-invasive means of indicating the epileptogenic zone. However, this test is not widely available in the US, and it is not known how often the additional information provided by SISCOM makes a difference to clinical decision-making.
In order to determine the contribution of SISCOM towards clinical decision-making in epilepsy surgery candidates, we will ask epileptologists at Mayo Clinic to consider case presentations given all clinical information except for SISCOM results, and then to reconsider those same cases in conjunction with SISCOM data. This will indicate the degree to which SISCOM influences decision making.
50 patients at Mayo Clinic (38 adults, 12 children) will be enrolled.
