Scientists say low-dose radiation can reduce brain damage from stroke

A low dose of radiation can reduce brain damage from trauma or stroke, as well as mitigate the movement disorders associated with these conditions, according to a study published in the scientific journal Brain, Behavior, and Immunity, Report informs.

Nearly half of survivors of traumatic brain injury or stroke experience movement problems and disabilities throughout their lives. In a new study, researchers found that low-dose X-rays can reduce the area of brain tissue lost in stroke by 43 to 51 percent.

In addition, X-rays accelerated the recovery of motor function. Thus, the mice took much less time to turn in the opposite direction on a narrow beam. Further analysis showed that low doses of X-rays stimulated the activity of genes associated with reducing inflammation.

Previous animal studies have shown that low-dose X-rays can stimulate the immune system, wound healing and cell growth, and prevent the loss of brain tissue in neurodegenerative diseases. Scientists believe that after additional testing, their method may find application in medicine.
