a fever affects the nervous system because it has a direct effect on the brain which is what controls the nervous system. The hotter it gets the more noticable the nervous system changes will be. IE If you are a child and you have a 104 fever you might be tired/sleepy, miserable, body cramps etc but once you get that fever down a few degrees the nervous system functions closer to normal allowing them to get back up and run around. If you are an adult and you get a fever of 104 your unable to get up and function (typically) even if you get the fever down a few degrees.
