Thank you for posting your query at DoctorSpring.com
I have noted your symptoms and the main problem seems to be in speaking and understanding, which are language functions. In most right-handed people, the language area is located on the left side of brain. So, we need to do an MRI scan to detect any problems in that part of brain. Also, any recurrence of brain tumor can be detected from the MRI.
In addition, you also seem to be suffering from stress and anxiety, which could impair the brain functions including memory, language and concentration. So, we need to treat your anxiety too. A consultation with psychiatrist/psychologist would help in that.
I hope it helps.
