Light may help halt dis­ease

The Courier-Mail - - NEWS - BRIGID O’CON­NELL

THE power of light is emerg­ing as a promis­ing way of slow­ing dev­as­tat­ing brain con­di­tions such as Parkinson’s dis­ease.

Clin­i­cal tri­als across the coun­try are test­ing whether ap­ply­ing “laser hel­mets” to a pa­tient’s head can im­prove symp­toms and halt the dis­ease. But a new Uni­ver­sity of Syd­ney study has found that ap- Aus­tralasian Neu­ro­science So­ci­ety’s an­nual sci­en­tific meet­ing this week – had in­formed hu­man clin­i­cal tri­als in Ade­laide, Bris­bane and Syd­ney, his team would now re­turn to mice stud­ies to con­firm them.

“There is pretty good ev­i­dence it works by us­ing a mild in­ter­mit­tent phys­i­o­log­i­cal stress to make your tis­sue more re­silient and bet­ter pre­pared to deal with what­ever in­jury it faces,” he said.
