<p>My hypothesis is that she is suffering from advanced multiple sclerosis. The extreme exhaustion along with the loss of motor function in her legs (Episode 15-Liar) and hands (Episode 21- Snow) are her most obvious symptoms.  However, the risky operation she undergoes is the only thing that make me question my theory.</p>

<p>In my theory, her disease is Friedreich's Ataxia. Symptons begins between the ages of 5 to 15. Muscle weakness in the arms and legs and loss of coordination are symptons.</p>

<p>It causes heart disorders. In Episode 20, she may be having a severe and painful tachycardia, and a following cardiac arrest. The surgery may be to implant a pacemaker, but another arrest killed her during the surgery. </p>

<p>Does anyone know what kind of illness Kaori Miyazono was suffering from?</p>
<ul>
<li>Kaori Miyazono is a girl about 14 years old</li>
<li>It has caused her to be hospitalized several times prior to the events of the series.</li>
<li>The disease causes her to collapse during a violin performance</li>
<li>It appears to cause her to have trouble walking, and is ameliorated by rehabilitation</li>
<li>It causes seizures that can cause unconsciousness, and lead to her being placed in the ICU</li>
<li>It is cured or temporarily halted by surgery, but the surgery is highly risky, and can result in patient death</li>
</ul>
<p>According to the <a href="http://shigatsu-wa-kimi-no-uso.wikia.com/wiki/Kaori_Miyazono" rel="nofollow noreferrer">series' wiki</a>, it is speculated that it was <a href="http://en.wikipedia.org/wiki/Bone_marrow_failure" rel="nofollow noreferrer">bone marrow failure</a>,</p>

<p> due to the change in her skin pigmentation and the need for an operation.</p>

In my theory, her disease is Friedreich's Ataxia. Symptons begins between the ages of 5 to 15. Muscle weakness in the arms and legs and loss of coordination are symptons.

It causes heart disorders. In Episode 20, she may be having a severe and painful tachycardia, and a following cardiac arrest. The surgery may be to implant a pacemaker, but another arrest killed her during the surgery.

It's a fictitious anime illness that functioned as a plot device as needed. There is no canonical mention of a specific illness and there would be no reason for the author to research one.

There is [a YouTube video](https://www.youtube.com/watch?v=FLhAHDJy3Bc) that falsely claims Kaori suffered from Friedreich's ataxia. The uploader is not a doctor or someone with any professional credentials that would allow him to make such a diagnosis.
