It is common to find, throughout life, that they tend to appear sad, negative or with a constant melancholic air.
However, when this persists over the years and begins to interfere with different aspects of the person’s life, we can speak of persistent depressive disorder.
What is persistent depressive disorder?
Previously labeled as dysthymia or dysthymic disorder, the latest volume of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) renames it persistent depressive disorder.
Persistent depressive disorder is considered a chronic affective condition that is distinguished because the person permanently experiences a depressed mood and melancholic and very low self-esteem.
Despite these indications, it does not correspond to major depression since it does not meet all the diagnostic requirements for it.
Although its origin is not clearly established, it is believed that there is a genetic component, that is, hereditary, which, together with psychosocial elements such as detachment or lack of stimulation and rewards during childhood, predisposes the person to suffer from this persistent depressive disorder.
Symptoms
Within the symptomatology of persistent depressive disorder, The symptom that most characterizes it is the patient’s experience of a persistent state of demoralization, uneasiness or grief and disconsolation; which lasts for at least two years.
When this disorder appears in children or adolescents, the manifestations go from being a depressed mood to being irascible or angry; and must last at least one year.
Likewise, the person must have two or more of these symptoms most of the time:
It is common for people with persistent depressive disorder to suffer from a negative self-concept, as well as a pessimistic view of their future, of others and of practically everything around them; so it is difficult for them to resolve any type of problem or conflict.
Causes
As mentioned above, the specific causes that cause this persistent depressive disorder or chronic depression are still unknown. However, it is known that this is usually hereditary, that it affects more men than women and that it is suffered by approximately 5% of the population
Likewise, it has also been established that the appearance of persistent depressive disorder is related to other mental conditions or disorders such as anxiety or substance abuse disorders such as alcoholism or drug addiction.
Another point in common that patients with chronic depression have is that at least 50% of them will suffer an episode of major depression throughout their lives.
Diagnosis
To make an effective diagnosis of persistent depressive disorder, the relevant health professional must take a medical history in which both the mood and the rest of the symptoms associated with this condition are evaluated.
In addition, a series of laboratory tests must be performed to rule out any possible physical origin of the disease.
