Stroke researchers report improvement in spatial neglect with prism adaptation therapy
Stroke rehabilitation researchers report improvement in spatial neglect with prism adaptation therapy. This new study supports behavioral classification of patients with spatial neglect as a valuable tool for assigning targeted, effective early rehabilitation. Results of the study, "Presence of motor-intentional aiming deficit predicts functional improvement of spatial neglect with prism adaptation" were published ahead of print in Neurorehabilitation and Neural Repair on December 27, 2013.The article is authored by Kelly M.

Stem cell discovery: Astrocytes could repair stroke brain damage
Stem cell researchers have discovered that astrocytes may prove useful against stroke and other brain disorders. Astrocytes - neural cells that form the blood-brain barrier and so control what can and cannot enter the brain from the blood supply - have previously been overlooked in this area of stroke research. A collaborative study published in Nature Communications suggests that astrocytes can do far more than simply support nerve cells (neurons)...

Stem cell study uncovers brain-protective powers of astrocytes
One of regenerative medicine's greatest goals is to develop new treatments for stroke. So far, stem cell research for the disease has focused on developing therapeutic neurons - the primary movers of electrical impulses in the brain - to repair tissue damaged when oxygen to the brain is limited by a blood clot or break in a vessel. New UC Davis research, however, shows that other cells may be better suited for the task...

Stem cell survival after transplantation impacted by melatonin pre-treatment
When melatonin, a hormone secreted by the pineal gland, was used as a pre-treatment for mesenchymal stem cells (MSCs) prior to their transplantation into the brains of laboratory animals to repair damage from stroke, researchers in China found that the stem cells survived longer after transplantation. Previous studies had shown that 80 percent of transplanted MSCs died within 72 hours of transplantation. By contrast, the melatonin pre-treatment "greatly increased" cell survival, said the researchers...

New Astrocytes Play Unexpected Role In Healing After Brain Injury
The production of a certain kind of brain cell that had been considered an impediment to healing may actually be needed to staunch bleeding and promote repair after a stroke or head trauma, researchers at Duke Medicine report. These cells, known as astrocytes, can be produced from stem cells in the brain after injury. They migrate to the site of damage where they are much more effective in promoting recovery than previously thought. This insight from studies in mice, reported online in the journal Nature, may help researchers develop treatments that foster brain repair...

In Stroke And Other Neurological Disorders, Nitric Oxide Damages Neurons And Blocks The Brain's Ability To Repair Itself
Nitric oxide, a gaseous molecule produced in the brain, can damage neurons. When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer's. Researchers at Sanford-Burnham Medical Research Institute recently discovered that nitric oxide not only damages neurons, it also shuts down the brain's repair mechanisms. Their study was published by the Proceedings of the National Academy of Sciences the week of February 4...

Stroke Recovery Aided By Stem Cells
Stem cells from bone marrow or fat improve recovery after stroke in rats, finds a study published in BioMed Central's open access journal Stem Cell Research & Therapy. Treatment with stem cells improved the amount of brain and nerve repair and the ability of the animals to complete behavioural tasks. Stem cell therapy holds promise for patients but there are many questions which need to be answered, regarding treatment protocols and which cell types to use. This research attempts to address some of these questions...
