The purpose of this research is to address the challenges of diagnosing and long-term management of epilepsy in participants whose seizures are not well captured by standard electroencephalography (EEG) tests and who cannot use or are not able to use more standard monitoring techniques. This research will compare the Minder System to standard of care in providing reliable seizure data. The Minder System was granted De Novo classification by the U.S. Food and Drug Administration (FDA) and is not investigational. Participants will consent to join the study and be implanted with the Minder device; or consent to join the study and continue with their Standard of Care (SOC) as a control group. Participants chose to be implanted with the Minder device will have the device implanted under their scalp. After implantation, participants will be randomly assigned to a group where their treating physician will have access to the EEG data collected by the Minder System or a group where their treating physician does not have access to the EEG data collected by the Minder System. Participants receiving the Minder System will not know which group they are in (blinded) until the study ends. All participants will continue to be followed by their treating physician and undergo assessments and visits until enough information is available to determine a treatment plan or the 6-month follow-up visit.
