When to Seek Medical Attention
Persistent depressive disorder can cause long-lasting depressive symptoms and should be medically or professionally assessed when they interfere with daily life. Seek prompt care when symptoms worsen, functioning declines, or hopelessness becomes significant. Emergency assistance is needed for suicidal thoughts or plans, inability to remain safe, severe self-neglect, or other immediate safety concerns.

Causes
The exact cause of persistent depressive disorder is not fully understood. Genetic and biological factors may contribute, and the condition can occur in families. Psychological and environmental influences may also affect vulnerability and persistence of depressive symptoms. The disorder is not caused by a single event in every person. A healthcare professional may consider medical conditions, medicines, substance use, and other mental health disorders when evaluating persistent low mood.
Risk Factors
Risk may be influenced by family history of depression, previous depressive episodes, prolonged stress, social difficulties, and other mental health or medical conditions. Persistent depressive disorder can occur at different ages, and symptoms may appear differently in children, adolescents, and adults. Older adults may experience additional difficulties with self-care, isolation, or cognitive symptoms. Having another form of depression or a history of significant psychological stress may increase the likelihood of persistent symptoms.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based on the history and pattern of depressive symptoms over time. A clinician evaluates mood, sleep, appetite, energy, concentration, self-esteem, hopelessness, functioning, and any associated mental health symptoms. The duration and persistence of symptoms are important because persistent depressive disorder is characterized by a long-standing course. Blood or urine tests may sometimes be used to look for medical conditions that can contribute to depressive symptoms.
