Hello, Thanks for choosing health care magic for posting your query. I have gone through your question in detail and I can understand what you are going through. Yes. Your concerns are right. Your symptoms of bipolar mood disorder can occur due to the frontal lobe mass or frontal lobe lesions. You will need mood stabilizer like valproate or lithium for your bipolar mood disorder. The lesion of the frontal lobe has not been specified. Get a consult from a neurosurgeon who can advice you if the lesion can be corrected. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you.
