Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It's quite disgusting that this information is not available from every stroke association and doctors group.

Study finds key physical difference in the brains of people with PTSD

Does your doctor even know about the 23% chance of stroke survivors getting PTSD? And what is s/he doing about it?

The part of the brain that helps control emotion may be larger in people who develop post-traumatic stress disorder (PTSD) after brain injury compared to those with a brain injury without PTSD, according to a study released today that will be presented at the American Academy of Neurology's Sports Concussion Conference in Jacksonville, Fla., July 14 to 16, 2017.
"Many consider PTSD to be a psychological disorder, but our study found a key physical difference in the brains of military-trained individuals with brain injury and PTSD, specifically the size of the right amygdala," said Joel Pieper, MD, MS, of University of California, San Diego. "These findings have the potential to change the way we approach PTSD diagnosis and treatment."
In the brain there is a right and left amygdala. Together, they help control emotion, memories, and behavior. Research suggests the right amygdala controls fear and aversion to unpleasant stimuli.
For this study, researchers studied 89 current or former members of the military with mild traumatic brain injury. Using standard symptom scale ratings, 29 people were identified with significant PTSD. The rest had mild traumatic brain injury without PTSD.
The researchers used brain scans to measure the volume of various brain regions. The subjects with mild traumatic brain injury and PTSD had 6 percent overall larger amygdala volumes, particularly on the right side, compared to those with mild traumatic brain injury only.
No significant differences in age, education or gender between the PTSD and control groups were found.
"People who suffered a concussion and had PTSD demonstrated a larger amygdala size, so we wonder if amygdala size could be used to screen who is most at risk to develop PTSD symptoms after a mild traumatic brain injury," said Pieper. "On the other hand, if there are environmental or psychological cues that lead to brain changes and enlargement of the amygdala, then maybe such influences can be monitored and treated."
"Further studies are needed to better define the relationship between amygdala size and PTSD in mild traumatic brain injury," said Pieper. "Also, while these findings are significant, it remains to be seen whether similar results may be found in those with sports-related concussions."
He pointed out that these participants' brain injuries were caused mostly by blast injuries as opposed to sports-related concussions. The study also shows only an association and does not prove PTSD causes structural changes in the amygdala.
