Ethical issues in research involving the aged and terminally ill population
Before discussing the ethical issues in research involving the aged population, we should ﬁrst identify this group of people accurately. As life expectancy increases, the exact deﬁnition of the ‘elderly’may need to be revised. The aged population could include the:
‘elderly’, i.e. people who are aged 65 years and above; ‘early elderly’, i.e. those from 65 to 74 years old; and ‘late elderly’, i.e. those over 75 years old.
