Some Gulf War veterans have different brains

Study adds to evidence of a physical basis for 'Gulf War syndrome'.

Regions of the brain important for thinking and memory may have shrunk in some veterans of the first Gulf War, according to a new study. The decline is at its worst in veterans who report more symptoms of what is commonly called 'Gulf War syndrome', the mysterious condition that has afflicted as many as one in seven veterans from the 1990-1991 war.
