Over the years I’ve heard many people advise dropping the word ‘disorder’ from dissociative identity disorder, citing
A) dissociation as a normal response to trauma, and
B) honoring subjective experiences as the primary reasons that it’s not helpful.
But the degree to which something is normal really has nothing to do with whether or not it’s a disorder. Disorders are referred to as disorders not because they’re abnormal, but because they actively, regularly, and severely disrupt people’s lives to such an extent that their ability to function is notably, even dangerously, compromised. And labeling a particular set of psychiatric symptoms with a particular psychiatric diagnosis is no more a call to ignore individual experience than it is to use labels like diabetes, hyperthyroidism, or influenza.
