Sensory stimulation protects against brain damage caused by stroke

Summary:
Mild sensory stimulation given soon after the first symptoms of a stroke can prevent a large area of the brain from becoming damaged, a new animal study shows. If applicable to humans, these findings could potentially help protect vulnerable brain tissue in patients with stroke.

Mild sensory stimulation given soon after the first symptoms of a stroke can prevent a large area of the brain from becoming damaged, a new animal study shows. If applicable to humans, these findings could potentially help protect vulnerable brain tissue in patients with stroke.

The research was presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience, held in San Diego.

"Current treatment options are very limited for people who suffer a stroke," said senior author Ron Frostig, PhD, of the University of California, Irvine. "Our findings suggest a possible new treatment option, one based not on drugs or specialized machinery, but on activating the cortex with a non-invasive, mild sensory stimulation."

Frostig and his colleagues stimulated the whiskers of rats that had undergone a procedure that mimics an ischemic stroke -- one caused by an interruption in the blood supply to the brain. This kind of stimulation imitates the exploratory whisker motion made by healthy rats.

The researchers found that 90 minutes of intermittent whisker stimulation led to a full return of cortical function. Furthermore, the whisker stimulation redirected blood flow within the circulatory system of the cortex -- effectively compensating for the blockage that had caused the stroke. Timing was crucial, however: whisker stimulation offered protection only when it was given within two hours of the onset of the stroke.

"Our results suggest that mild sensory stimulation is capable of saving the cortex and restoring pre-ischemic levels of function if given right after the stroke begins," Frostig said. "This line of research may eventually add to the arsenal of existing stroke treatments and thus help to ease the high emotional, physical, and economic cost of stroke," he said.
