Hello. Thanks for using DoctorSpring.com for posting your query.
I have gone through your post in detail and I can understand what you are going through. Panic disorder can be very troubling and repeated panic attacks can lead problems with concentration leading to pseudo (false) memory problems.
Although you are taking Escitalopram and Bupropion it is not helping you much. This suggests that you need to change medicines for the better. Among the available options, a better drug would be either Paroxetine or Venlafaxine. Both are good drugs and very effective. I generally use Paroxetine as a first line for all of my anxiety disorder patients.
Also, along with these medicines you may try restarting with cognitive behavioral therapy as well. This will help in bringing out remission along with the medicines.
Hope this helps. If you have any further queries, do let me know.
Kind regards,
Dr. Srikanth Reddy MD.
