Persistent depressive disorder, sometimes called dysthymia, involves depression symptoms that are generally less severe but last much longer, usually for at least two years.
That long duration can make low mood, reduced energy, sleep changes, or trouble managing daily life feel familiar rather than treatable. Familiarity does not make your concern unimportant. A clinician can explore how long symptoms have lasted, how often they occur, and how much they affect your work, relationships, caregiving, and well-being.
