I think this topic is important in PTSD.
It’s not about trying to become an ambidextrous genius, or even being ambidextrous. It is about basic biology, and how people with PTSD can benefit from using both cerebral hemispheres, by practicing an activity right and left handed that is neurologically intense.
To illustrate what I mean, I am going to place a time frame for what happened with me, using events which are relevant to this topic.
1959 - born, grow up with abusive father.
1980 – started playing acoustic music, at the age of 21. I continue this up to this day.
2000 – intervention forced me into drug rehab, I was addicted to hydrocodone. This is from my story “I Believe PTSD is Curable”
“Once at the facility, I underwent lengthy and very extensive psychological testing. I was told I had PTSD, and in addition I seemed to have multiple diagnoses. I told them I already knew about the PTSD. I did ask what could be done for it. There was very little that could be done, if anything. But they could get me into a life of sobriety, and that would make my life better.
I was also diagnosed as severely schizoid. Schizoid means “like schizophrenia”. Severe enough, that for all real purposes, my life was identical to a person with true schizophrenia.”
2002 – 2nd intervention forced me into a 2nd rehad. Again the following is from the same story.
“Throughout your life, you have been using a psychological defense mechanism we call compartmentalization. That means when something traumatic happened, you put it in the back of your mind, kind of like a little box. Well now you do not have any boxes left. You have used them all." I remember the words, used up, being mentioned. He also said, "You can not take another hit in life. You will kill yourself."
2003 – continued to struggle with ptsd and dysfunctional life.
12/2003 – start playing music left-handed. 3 months later
3/2004 – announce to family, friends, and coworkers, I don’t think I have PTSD.
4/2004 – voluntarily undergo psychiatric testing. Again from the same story
“The head psychologist, who had a Ph.D. from a prominent university, went over the results with me. The tests showed that there was not anything that was wrong, and she was confused as to why I was even there. I asked her specifically if the results indicated PTSD, and she specifically stated there were no symptoms of PTSD, or anything else, for that matter, indicated on the test.”

What is written above was easy to write about and describe, but the rest is not so easy, because there are not any words for it that I have been able to find, so please bear with me.
In addition, in March 2004, another phase of healing started to occur, and I think it relates to our topic.
I have seen individuals in 12 step programs struggle for a time, then a light comes on, you can see it on a person’s face. I have heard it called “a moment of clarity”. Confusion, pain, desperation, give way to a calm peaceful feeling. In AA I experienced it a time or two, myself.
Well this was like “an HOUR OF CLARITY”. It happened without fail, every day and became a regular part of my life. It happens upon awakening, every day, and lasts for about an hour, right after I would wake up. It is very, very peaceful.
I am certain this occurred because of an existing hemispherical imbalance of some type, because of the PTSD. I believe this occurs because our mind has a capacity for balance, if we give it the means to do so.
I no longer have flashbacks, I don’t jump out of my skin at sudden noises. I don’t have nightmares, and my mind is not stuck on traumatic events from years ago. I am not depressed, or suffer from undo anxiety. I do not take ANY psychotropic meds, and I will have 5 years of sobriety this Thursday 2/22/7.
