I did not have MVD and have been reading mvd threads in here but I cannot find an answer so I was wondering since MVD is brain surgery do people who have MVD done....are you given a psychological test before the MVD ? Are you sent for psychological evaluation before you have an MVD ??? Because everyone must have one before they can be approved for PNS . So just wondering how brain surgery is treated compared to same day PNS surgery ???? Is there a psych evaluation before MVD ???????PEACE BMW
