Which of the following mental health issues is NOT listed as a disqualifying condition?

Chronic anxiety is not classified as a disqualifying condition in the context of the DOT medical standards. The medical guidelines primarily focus on mental health conditions that significantly impair a person's ability to operate a commercial vehicle safely. Conditions that may severely affect judgment, perception, or the overall mental stability required for safe driving are specifically noted as disqualifying.

Chronic anxiety, while it can impact daily functioning, does not automatically disqualify a person if it does not lead to significant impairment in judgment or functioning. This differentiates it from the other options, which are clearly defined as causing severe enough symptoms that could endanger safety on the road, such as mental conditions affecting judgment or perception, various forms of dementia, and any history of suicidal behavior or ideation that indicates a person may be a danger to themselves or others. Therefore, chronic anxiety stands out as the condition that is not expressly listed as a disqualifying factor.
