The human body is complex but it has a lot of global variables. All a virus needs to do is twiddle these global variables and sometimes it will have a beneficial effect for propagation. Any part of the body can chuck any molecule into the blood stream and have it transported round the body. Virus evolutionary processes can ‘engineer’ for things to cross the blood brain barrier just like pharmaceutical researchers. Even if you can’t get into the brain, you can still drastically alter behaviour by messing around with the rest of the body.
