The disorder has caused debilitating muscle spasms, sometimes breaking her ribs.
She canceled her world tour and Las Vegas residency due to the condition.
Dion is undergoing intensive therapy but remains uncertain about returning to the stage.
A documentary about her health journey, 'I Am: Celine Dion,' will premiere on June 25.
