<s>[INST] I have unexplained severe tremors & have been to a neurologist to be tested for seizures where I was cleared for anything related to this. Everything was normal on EEG & MRI so nothing in the neuro department. Dr. suggested I see cardiologist as I have also had a couple of unexplained episodes of syncope . Not sure whether the two are related but both have happened while driving. One episode of syncope caused a traumatic car accident & I m thankful to walk away from it & no one was injured. Therefore, I m hoping you can provide me with some type of answer. [/INST] Hi, 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 findings. 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. Best wishes, Dr Sudhir Kumar MD DM Senior Consultant Neurologist </s>
