...First Do No Harm(1997)

Overview:

When Lori Reimuller learns that her young son Robbie has epilepsy, she first trusts the judgment of the hospital staff in how best to bring it under control. As Robbie's health slides radically downhill, however, she becomes frustrated and desperate, and so does her own research into the existing literature on treatments. When she decides to try an alternative treatment called the Ketogenic Diet, devised long ago by a doctor from Johns Hopkins, she is met with narrow-minded resistance from Robbie's doctor, who is prepared to take legal action to prevent Lori from removing him from the hospital.
