Persistent Depressive Disorder
Persistent depressive disorder describes a long-lasting depressive pattern that may feel less dramatic than a major episode yet steadily shape energy, confidence and daily life.
When low mood becomes the background
Possible signs include low mood, low energy, poor concentration, low self-esteem, hopelessness and changes in sleep or appetite. Because the pattern is chronic, a person may conclude “this is just who I am” and may not recognise it as something that deserves assessment.
People can continue working and caring for others while experiencing substantial internal effort. Periods of more severe major depression can also occur on top of the persistent symptoms.
Assessment and differential diagnosis
Assessment reviews the long-term course, periods of improvement, functional impact and any current safety concerns. A clinician considers major depressive episodes, bipolar-spectrum conditions, trauma, substance use, medicines and physical health. Long duration alone does not make self-diagnosis reliable.
Treatment and support
Psychotherapy may address entrenched patterns of withdrawal, hopelessness, self-criticism and relationship difficulties while supporting gradual re-engagement with valued activity. Medication may be considered by a doctor. Treatment is individualised and may need patience because the pattern has often been present for years.
