I don’t understand what your question is.
You mentioned having two previous EEG’s that were normal but your last one was abnormal. Since you didn’t experience a seizure during the first two EEG’s the tests were normal. Normal tests are very common in Epilepsy patients. During your last EEG you had some seizure activity even though you may not have shown any seizure symptoms.
It appears you have TLE (Temporal Lobe Epilepsy) with Focal Aware Seizures (formerly known as Simple Partial Seizures) which appear to be controlled. As far as the new MRI is concerned it’s always a relief to know there are no structural problems other than the expected age related changes. But if your seizures are controlled there is no reason for surgery or electronic devices. Unless your having new symptoms or more frequent seizures another MRI seems pointless other than for piece of mind.
Wishing you health and happiness,
