No single test can&nbsp;confirm or rule out multiple sclerosis (MS), but the following techniques can help your doctor make a diagnosis: 
<ul>
 <li>A medical history and neurological exam can help a doctor identify symptoms that may be caused by MS and evaluate a person's mental and language functions, as well as information on movement, coordination, balance, vision and other senses. According to the <a href="http://www.netreturns.biz/healthinfo/bouncelink.aspx?shortcut=nmss" target="_blank">National Multiple Sclerosis Society</a>, a medical history and neurological exam often provide enough evidence to diagnose MS. Other tests are used to confirm the diagnosis or provide additional evidence if necessary. </li>
 <li>Magnetic resonance imaging (MRI) scans can reveal patches of injured tissue in the central nervous system that suggest MS. Repeat tests can show whether diseased areas are changing. </li>
 <li>A sample of cerebrospinal fluid may be analyzed for abnormal proteins. </li>
</ul>
