In addition to chronic low moods, common symptoms of this mood disorder include:
- Feelings of hopelessness or helplessness
- Trouble sleeping or daytime sleepiness
- Poor appetite or eating too much
- Fatigue or low energy
- Low self-esteem
- Trouble concentrating or making decisions
A diagnosis of dysthymic disorder in adults requires at least a two-year history of depressed mood for most of the day on most days, along with at least two of the symptoms noted above. Although some symptoms may overlap, you may be less likely to have weight or sleep changes with dysthymic disorder than with depression. You may also tend to withdraw more and have stronger feelings of pessimism and inadequacy than with major depression.
