Mild depression, or dysthemia, is a chronic form of depression. The National Institutes of Health (NIH) notes that mild depression is a less serious form of depression, where symptoms occur every day for at least 2 weeks.
Risk Factors
The Mayo Clinic states that people with a family history of depression or dysthemia have an increased risk of developing mild depression. Other risk factors include chronic medical conditions and stressful events.
Frequency
Women are more likely to develop mild depression, according to the NIH. In total, mild depression patients make up 5 percent of the population.
Symptoms
The NIH notes that symptoms of mild depression include poor concentration, feeling hopeless, fatigue and low self-esteem. Sleeping problems, such as insomnia and hypersomnia, also occur with mild depression. Some patients may have a poor appetite or overeat.
Treatment
Treatment options for mild depression include selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants and cognitive behavioral therapy. The NIH states that medication does not work as well with mild depression compared to major depression.
Complications
If mild depression is not treated, it can progress into major depression, according to the NIH.
