Blackouts are indeed viewed as a significant indicator of alcoholism because they reflect a person's inability to form new memories due to the effects of alcohol on the brain. This inability can indicate a detrimental level of alcohol consumption, which may disrupt normal cognitive functions. In many cases, blackouts signify that the individual has reached a level of intoxication that not only compromises their memory but can also lead to dangerous behaviors and decision-making. Furthermore, experiencing blackouts frequently can alert family and friends to the severity of the drinking problem, signaling the potential need for intervention or treatment.

While frequent mood swings, physical health decline, and social withdrawal can all be components of alcohol use disorders, they may not be as definitive in isolation as blackouts. For instance, mood swings can arise from various mental health issues, physical health decline might stem from numerous health problems unrelated to alcohol, and social withdrawal can sometimes be a response to a range of factors, including anxiety or depression, rather than alcohol use specifically. Thus, the presence of blackouts often serves as a clear and alarming sign of an advanced stage of alcohol misuse.
