Verified step by step guidance

1. Understand that Alcohol Use Disorder (AUD) is a clinical diagnosis based on behavioral patterns and symptoms, not just a single measurement or event.
2. Recognize that AUD diagnosis involves assessing a pattern of problematic alcohol use that causes significant impairment or distress over time, rather than relying solely on blood alcohol concentration levels.
3. Know that a single episode of heavy drinking does not meet the criteria for AUD; the diagnosis requires a recurring pattern of problematic use.
4. Be aware that daily alcohol consumption is not a requirement for AUD diagnosis; the disorder can be diagnosed based on the impact and pattern of use regardless of frequency.
5. Conclude that the true statement is that AUD is diagnosed based on a pattern of problematic alcohol use leading to significant impairment or distress, aligning with diagnostic criteria such as those in the DSM-5.
