I know the frustration level we have, even for the most patient person, is much higher. I also had a lacunar stroke, no aphasia, but I feel my personality is different. More annoyed at anything. Mine was 4 years ago, and I think I am different than I was, less positive all around even tho I worked hard at it to recover muscle/leg use. It is also possible being herded into the VA 's new "no pain meds for you" program of serious meds reduction (for other health problems) also did NOT help.
So my reply to both Melly and Phoebe, to all, actually is behaviors over time will be different person to person-- how well we respond to the event, our recovery, add in other life issues, stressors (financial, family, lack of resources, etc) and this medical life changer will affect anyone!
I find I no longer tolerate stupid behavior, rudeness, especially from strangers or "front desk" type staff. I even called the home insurance guy a "really dull man"...he HEARD that of course, came unglued, but he wan't hearing my issue about a property damage problem.
There was a really silly movie called HENRY where the family man (harrison ford) turns into a lovely person when he was a total jerk before) ...dream on. Our brains are BEYOND complex, we may never be what we were in personality, or coping, but if FAMILY will sett firm but gentle "ground rules" it may help the person COPE..and realize they can't be acting out endlessly.
Here are two things I have read on dynamics of anger handling:
1. a family had a toy doghouse on top the refrigerator..each member had a little plastic dog... when mom was upset with anyone of her brood or husband, she placed that one's dog in the doghouse..a quick glance could tell you where you stood. so you could address the issue sooner.
2. The child's "time out" rule.. when they act out - say"you have 2 more minutes to rant, then I ask you to calm down." some hand them a foam bat to go hit a stuffed toy, or hand a small "scream here" pillow.
There are ways to address the person's acting out without constantly causing clashes and disharmony for all.
I live alone..so when I hung up from arguing with the insurance 'dullard' I picked up the cuddly cat, closed my eyes and let her warm, affection sooth my temper. it works every time
