Which symptom might indicate a risk for imminent manic episode?

A symptom that might indicate a risk for an imminent manic episode is sleep disturbances. In individuals with bipolar disorder, changes in sleep patterns are often one of the earliest warning signs of a manic episode. Insomnia or decreased need for sleep may lead to increased energy levels and activity, which can escalate into a full-blown manic episode if not addressed.

Sleep disturbances can disrupt the body’s natural circadian rhythms, contributing to mood instability and other symptoms associated with mania. Recognizing and monitoring these changes can be crucial for mental health professionals and individuals prone to mania, as early intervention can help mitigate the severity of the manic episode.

While other options may have their relevance in other contexts, such as isolation indicating depressive symptoms or heightened motivation potentially being healthy, they do not have the same direct correlation with the onset of a manic episode as sleep disturbances do.
