Post AVM

I am 54 yrs. old. My AVM was removed in 1982. I have been working in Behavior health for the last 28 yrs. the area the AVM was located was in the memory area of the brain. Within the last year or so I have had a difficult time remembering words/definition of words. And yes, become anxious at that time. Is this from the AVM? And if so, will it become worse.
