The regulations were loosened with ADAAA to be more flexible with episodic conditions and illnesses in remission. ADA applies when an impairment or illness is active rather than dormant. When symptoms are in remission, individuals may still be covered if they require an accommodation to continue controlling symptoms. Episodic conditions and illnesses in remission could be impairments such as: Bi-polar disorder, depression, cancer, PTSD, multiple sclerosis, GI diseases, migraine headaches, etc.
