Dysthymia is the medical term for chronic or mild depression. People who suffer from mild depression, often called a dysthymic disorder, usually have symptoms that last for two years or longer. Unlike people suffering from a major depressive, people experiencing mild depression are able to perform their daily activities. Symptoms of mild depression will vary from patient to patient. The American College of Physicians classifies patients displaying at least two of these symptoms as mildly depressed.
Change of Disposition
The once-cheery and optimistic person who suddenly displays an attitude of gloom and doom may be experiencing mild depression. Suddenly, the half-full glass is considered half empty. Even mild criticism can cause an overreaction, which may result in tears and rage. The formerly easy-going person may display irrationally impatient behavior when forced to wait for a bus, elevator or restaurant service.
Loss of Interest
The mildly depressed person loses interest in her favorite activities, hobbies and foods. Motivation is lacking, and the ability to maintain friendships may be impaired.
Loss of Self Confidence
The mildly depressed person may lack the confidence to apply for a new job or a promotion, or to flirt with someone he finds attractive. He may be hesitant to learn a new activity, or to enhance the skills of the activities he enjoys.
Lack of Energy
The former marathon runner who can barely run a mile may be suffering from mild depression. Some mildly depressed people lack the energy to perform simple tasks, such as walking their dog or even washing their hair.
Impaired Concentration
The mildly depressed person may read a book or watch a television show and have difficulty following the plot. Impaired memory and decision making may also be apparent.
Impaired or Excess Sleep
While people suffering from mild depression may have the desire to sleep throughout the day, in some cases they may have insomnia.
Weight Gain or Weight Loss
While mild depression is often characterized by a loss of appetite, in some cases the patient may overeat as an attempt to mask or alleviate the symptoms of depression.
