Some people consider it best to use person-first language, for example "a person with a disability" rather than "a disabled person."

The cohort cannot therefore be defined as a group of people who already have the disease.
Mannheim defined a generation (note that some have suggested that the term cohort is more correct) to distinguish social generations from the kinship (family, blood-related generations) [2] as a group of individuals of similar ages whose members have experienced a noteworthy historical event within a set period of time.
