Deans' stroke musings: Researchers link post-right stroke delirium and spatial neglect to common brain mechanism

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 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:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. 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 lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Researchers link post-right stroke delirium and spatial neglect to common brain mechanism

This is not specific enough to be of any use. What parts of the right brain damage would cause this? I had a right brain stroke, picture of damage down at the bottom of blog. Had slight spatial neglect, resolved quickly, never had delirium. Of course followup is needed which will never occur.

Kessler Foundation scientists foresee potential for strategies for minimizing risks for cognitive complications after right-brain stroke

Kessler Foundation

East Hanover, NJ. Nov.20, 2017. Stroke researchers at Kessler Foundation have proposed a theory for the high incidence of delirium and spatial neglect after right-brain stroke. Their findings are detailed in "Disruption of the ascending arousal system and cortical attention network in post-stroke delirium and spatial neglect," which was published online ahead of print on September 27, 2017 by Neuroscience & Biobehavioral Reviews. The authors are Olga Boukrina, PhD, research scientist, and A.M. Barrett, MD, director of Stroke Rehabilitation Research at Kessler Foundation.
Delirium and spatial neglect affect approximately half of individuals with right brain stroke, increasing their risk for prolonged stays and rehospitalization. Identifying the factors associated with these often disabling conditions is the initial step toward minimizing their impact on recovery and rehabilitation. Stroke survivors with spatial neglect are more likely to develop delirium, an acute disorder of attention and cognition, suggesting that these conditions may share a common brain mechanism.
"The brain networks for spatial attention and arousal may underlie the impairments in delirium and spatial neglect," noted Dr. Boukrina. "These networks comprise ascending projections from the midbrain nuclei and integrate dorsal and ventral cortical and limbic components. We propose that right-brain stroke disproportionately impairs these cortical and limbic components, causing the lateralized deficits that characterize spatial neglect," she explained. "Spatial neglect may lower the threshold for delirium, which could account for the higher incidence of both post-stroke complications."
Further research is needed in order to identify individuals at risk soon after stroke, and develop an effective protocol for reducing the risk of these complications and their contributions to mortality and morbidity.
