Can we apply "disability" to all abilities, like being hungover and therefore temporarily sensitive to light and sound, or should it apply to specific ones, like being injured and therefore temporarily sensitive to light and sound?
That seems like something that will shift towards one or the other as society talks more openly about disabilities.
For instance if you're taking a legal drug that habituates you, they don't like calling you an addict, so you're experiencing cessation syndrome. A change in legal status of the drug would presumably lead to a terminology change.
And I'm not going to revisit DSM fights, but suffice to say, a number of changes made to certain diagnoses over time reveal more about sociopolitical changes than anything having to do with psychiatry.
