Which of the following is true regarding diabetes symptoms?

Diabetes symptoms can indeed include changes in behavior, especially during episodes of hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar). When blood sugar levels are not well managed, they can lead to confusion, irritability, or unusual behavior as the brain and body are impacted by the fluctuating glucose levels. Recognizing these behavioral changes is critical for prompt intervention, as they may indicate that the person is experiencing a serious medical issue related to their diabetes.

Other options mention symptoms that are not typically associated with diabetes. For example, while cool, pale skin can indicate other medical conditions, it is not standard for diabetes. Hallucinations are not a direct symptom of diabetes, although severe complications might lead to altered mental states. Finally, while diabetes can lead to serious situations, the symptoms themselves do not always indicate an immediate crisis; they can range from mild to severe depending on the individual's blood sugar levels and overall management of the condition.
