Any single disease may fall within several of these classifications.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.britannica.com&amp;#x2F;science&amp;#x2F;human-disease&amp;#x2F;Classifications-of-diseases&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.britannica.com&amp;#x2F;science&amp;#x2F;human-disease&amp;#x2F;Classificat...&lt;/a&gt;</text><parent_chain><item><author>tejohnso</author><text>&amp;gt; Two children diagnosed with the disorder can have no overlapping symptoms.&lt;p&gt;Is there a precedent for this with other disorders?

<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>projectramo</author><text>I think there are precedents.&lt;p&gt;It happens because there is so much overlap in most patients, and symptoms tend to occur in clusters.&lt;p&gt;General delays in motor skills and language skills are quite prevalent in many conditions. If you google videos of kids with autism, you will see varied abilities.&lt;p&gt;I am hesitant to go into more detail because this is an area that causes a great deal of anxiety for parents and discussions are often sensitive. One surefire way to annoy a parent and get into an argument is to claim their kid does or does not have a condition that differs from their own opinion. (And I can see why it would bother them).</text><parent_chain><item><author>tejohnso</author><text>&amp;gt; Two children diagnosed with the disorder can have no overlapping symptoms.&lt;p&gt;Is there a precedent for this with other disorders?
