system is made up of your brain and the many different neurons that transmit signals to and from the body. One of the most common ways the nervous system deteriorates is when the connections between two neurons diminish‚ or build plaque. The brain uses neurons to send signals to each other‚ in order to get our bodies to move‚ think‚ and react to different situations. As people age‚ the neurons lose their normal functioning quality.
