People with invisible or fluctuating disabilities can face skepticism about whether they need support. Appearance, a good day or ability to do one activity does not settle that question.
Use the current legal definition
The ADA Amendments Act broadened disability coverage after court decisions had narrowed it. The older Toyota v. Williams approach discussed in the original article should not be presented as the current test.
An impairment that is episodic or in remission can qualify when it would substantially limit a major life activity while active. Coverage is intended to be assessed broadly. A person is not automatically excluded because they can shower, eat or work sometimes.
Different systems ask different questions
ADA protection, a workplace accommodation, Social Security benefits and a particular program's eligibility are separate matters. Being able to work sometimes does not by itself answer every benefit or accommodation question. Seek advice for the actual system and facts.
An accommodation request also involves what is needed and reasonable in that setting. A diagnosis, somebody else's opinion or a general article cannot resolve every request.
For service-dog teams
Under ADA public-access rules, the dog must be individually trained in work or tasks directly related to the person's disability. Assistance may be needed intermittently. Comfort from presence alone is different from a trained task.
Do not rank a stranger's disability or task by how visible it is. The person, relevant professionals and an appropriate trainer can discuss practical support, safety and the dog's welfare. A voluntary registry does not decide a person's legal disability status.
