Thank you for posting your query.
Based on the symptoms, the two possible diagnoses are still seizures and syncope
I should clarify that seizures are a clinical diagnosis and not purely based on the EEG and MRI
EEG may be normal in about 50% of cases of seizures. MRI of brain may also be normal in many cases of seizures.
So, my suggestion would be to see a cardiologist to evaluate for syncope. If that is normal, then, an empirical course of anti epileptic drugs may be used.
