HI,
I'm a spouse of a sufferer..He gets super angry and use to have super rages.. Definitely not fun.. His "triggers" were various things (due to being in the military) sights, sounds, smells, attitudes, voice tones, almost anything, rarely was it every time tho.
I find if it's possible to re-focuse them that's what works for ranger. Not always possible. I try to get him to go some place else or do something to get his mind ON something else. So he doesn't have to"over think" the situation.
Not all things work all the time or for others unfortunately. You'll have to find what works for your sufferer. As a carer, patience is great, tho sometimes it is very difficult to keep up. I have to take time out for my self. I read, take pictures, weld, build bird houses. Sometimes I go have a mother/daughter day w/my daughter and we go have lunch just talk....

She's super as she is a flight communications specialist (dispatches medivac) and works as an EMT/firefighter so she sees and understands a lot of stuff....
hang in there...keep reading and know you are not alone...
suffers are looking for help and answers, just as much as us carers are doing the same..
I pray that we all find our answers...
Hugs to you all

Donna
