Overview
Major Depressive Disorder
Major depressive disorder is a mood disorder characterized by persistent depressed mood or loss of interest that interferes with daily life. Symptoms may affect sleep, appetite, energy, concentration, and functioning and generally persist for at least two weeks. Depression can affect people of different ages and may require ongoing treatment.
Psoriatic Arthritis
Psoriatic arthritis is an inflammatory form of arthritis associated with psoriasis, a condition that affects the skin and may also affect the nails. It can cause pain, stiffness, swelling, and reduced movement in affected joints. The disease may involve different joints and can affect the fingers, toes, spine, or other areas. Symptoms may vary over time, with periods of increased inflammation and periods of fewer symptoms.

Major Depressive Disorder
Diagnosis is based on symptoms, their duration, their effect on daily functioning, medical history, and clinical assessment. Major depression generally involves depressed mood or loss of interest lasting at least two weeks along with other symptoms. Healthcare professionals may also assess for medical conditions, medicines, or substance use that could contribute to symptoms.
Psoriatic Arthritis
Diagnosis of psoriatic arthritis is based on the pattern of joint symptoms, physical examination, medical history, and evidence of psoriasis or related skin and nail changes. Imaging studies such as X-rays, ultrasound, or magnetic resonance imaging may help identify inflammation and joint damage. Blood tests can help evaluate inflammation and may be used to help distinguish psoriatic arthritis from other types of arthritis. There is no single test that independently confirms every case.
Prevention
Major Depressive Disorder
Major depressive disorder cannot always be prevented. Maintaining supportive social connections, regular physical activity, adequate sleep, healthy routines, and appropriate management of chronic medical conditions may support mental well-being. Recognizing persistent changes in mood or functioning and seeking professional help early may reduce the impact of depression.
Psoriatic Arthritis
Psoriatic arthritis cannot always be prevented because its exact cause is not fully understood. Managing psoriasis and maintaining regular medical care may help identify joint symptoms at an early stage. Regular physical activity can help maintain joint movement and general fitness, while maintaining a healthy weight may reduce stress on weight-bearing joints. Protecting the joints from unnecessary injury and seeking medical evaluation for persistent pain, swelling, or stiffness can support early management.
Risk Factors
Major Depressive Disorder
Risk of major depressive disorder may increase with family history, previous episodes of depression, stressful or traumatic life events, certain chronic medical conditions, long-term pain, substance or alcohol use, and other mental health conditions. Depression can occur even without an identifiable risk factor or family history.
Psoriatic Arthritis
Having psoriasis is an important risk factor for psoriatic arthritis. A family history of psoriasis or psoriatic arthritis may increase susceptibility because genetic factors can influence the immune response. Other autoimmune or inflammatory conditions may also be associated with increased risk. People with psoriasis who develop persistent joint pain, swelling, stiffness, or changes in movement should discuss these symptoms with a healthcare professional.
