Which of the following subcategories of alcohol use disorder onset is NOT found in the elderly?

The choice indicating early-onset alcoholism is the correct answer because this category typically refers to individuals who start drinking heavily at a younger age. In the context of the elderly, early-onset alcoholism does not apply, as it is characterized by problems arising from alcohol use that were established earlier in life, usually before the age of 25.

In contrast, late-onset alcoholism usually emerges after age 60 and is often influenced by life changes such as retirement, loneliness, or loss, which are more relevant to older adults. Delayed-onset alcoholism is also relevant as it can describe the emergence of problematic drinking later in life, possibly due to cumulative stressors. Late-onset exacerbation drinking refers specifically to an increase in alcohol consumption in those who may have previously had a stable pattern of drinking, again aligning with issues common in the elderly demographic.

Thus, the concept of early-onset alcoholism does not pertain to the aging population, making it the correct choice in this context.
