Brain can repair itself from damage
Washington, Nov 16 : Results from new studies have revealed that the brain has a remarkable capacity to repair itself from damage.
The animal studies propose ways to prevent or limit damage after blood and oxygen deprivation and blood clots.
Stroke is the number one cause of long-term disability and the third leading cause of death in the developed world. Limiting the damage caused by stroke would improve patient prognosis.
An animal study found that sensory stimulation protects against stroke damage if administered within the first two hours of stroke onset, whether animals were awake or anaesthetized.
Another study suggested that auditory stimulation delivered soon after a stroke protects from damage.
Scientists also identified a cellular mechanism that blood vessels use to clear their own clots.
"The brain is remarkably robust," said Mark Paul Goldberg, MD, a neurologist at the University of Texas Southwestern Medical Center and an expert in brain injury.
"Many of the brain's systems have mechanisms that allow it to protect or repair itself. With the help of further research we can better understand these mechanisms and find new applications for treating brain injuries," he added
The findings were presented at Neuroscience 2011, the Society for Neuroscience's annual meeting. (ANI)
