A rumour of a wild phase, years ago

A 35-year-old presents with two weeks of low mood, anhedonia, and poor sleep, meeting criteria for a moderate depressive episode. Her intake form includes a note from a family member mentioning she 'might have had some kind of wild manic phase a few years ago,' but no clinician ever assessed her at that time, and the family member cannot recall any specific symptoms, how long it lasted, or how it affected her daily life.

Based only on what is described so far, what is the best classification decision?
