According to the definitions provided, how is 'elder' defined?

The definition of 'elder' typically refers to a person who is aged 65 years or older. This age is significant as it aligns with various social support programs, including Medicare eligibility in the United States. By using 65 as the threshold, this designation helps to identify individuals who are likely to require specific legal protections and support services, particularly in the context of elder abuse and neglect. As a standard age, it provides a clear guideline for defining a demographic that may be vulnerable and necessitate special consideration within legal and care frameworks.

The other options suggest different age thresholds or criteria that may not align with the widely accepted definition used in elder abuse and neglect discussions. These variations could lead to inconsistencies in policy implementation and support services aimed at older adults.
