Note: Dysthymic disorder was a mood disorder in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-4). However, in the most recent version of the DSM, the DSM-5, this condition has been renamed persistent depressive disorder (PDD). 

Persistent depressive disorder, often called dysthymia, is a depressive disorder that lasts for over two years for adults and over a year for children and adolescents. To understand dysthymic disorder, it can be helpful to look at the diagnostic criteria for this condition and how to find support if you believe you are living with it.

What is dysthymia?

Dysthymia, properly called persistent depressive disorder (PDD), is a depressive disorder lasting for over two years. It causes similar symptoms to major depressive disorder (MDD). However, the symptoms are often milder and last for longer. Try thinking of it as a milder but chronic major depressive disorder. The word “dysthymia” comes from the Greek language and roughly translates to “bad state of mind.”

PDD is sometimes referred to as a “low-grade” or low-level” depression” by psychiatrists. However, this labeling doesn’t mean that the condition is not severe or does not cause functional impairments. Although the symptoms may be less harsh, their chronic nature can interfere with a person’s livelihood.

Those with major depressive disorder often know they have a more baseline mood that can sometimes be considered positive. In addition, major depressive episodes may not last every day for years. Those with a chronic condition like dysthymia may not experience any positive emotions for years. In addition, many people living with PDD experience major depressive disorder. 

Based on statistics, PDD is rarer than major depression. Approximately 1.5% of adults in the US are diagnosed with PDD annually, while 7% of those with major depressive disorder are diagnosed. In addition, to receive a diagnosis of persistent depressive disorder, symptoms must occur non-stop for at least two years. To be diagnosed with MDD, symptoms must occur every day for at least two weeks.

What are the symptoms of PDD? 

According to the DSM-5, individuals must have at least two of the following symptoms for two years or more to be diagnosed with PDD

A poor appetite or overeating

Appetite changes can be a common symptom of depression and may go both ways. Some people with PDD may struggle to eat enough to remain healthy, whereas others may overeat. Some of the foods people crave when anxious, stressed, or depressed may be unhealthy, which can lead to adverse health impacts and cause a desire to eat even when one is not hungry. In some cases, over or undereating leads to weight loss or gain, which may have health impacts for some people. 

Insomnia or hypersomnia

Like appetite changes, it can be typical for those with depression to struggle to sleep or wake up. Struggling to fall or stay asleep is called insomnia, whereas sleeping too much or struggling to wake up in the morning is called hypersomnia, which may be associated with the fatigue that often accompanies depression. 

Some people experience both insomnia and hypersomnia. For example, someone may struggle to fall asleep at night. Still, when they fall asleep late in the night or early morning, they may struggle to wake up on time and could sleep for over eight hours, which is higher than average for adults. 

Treating sleep conditions may require the assistance of a doctor who can prescribe sleeping medication or offer treatment plan recommendations. Consult your provider before starting, changing, or stopping any medication or treatment. 

Low energy and fatigue

Having little to no energy can make performing daily tasks difficult. If a person has the strength to complete tasks when they wake up, depression can cause their energy to be quickly expended, causing fatigue later in the day. Excess fatigue can be dangerous and may cause a person to fall asleep at work, on the road, or in other dangerous situations. 

These symptoms, sleep disturbances, and concentration challenges can make PDD like chronic fatigue syndrome (CFS). However, to get a diagnosis of CFS, an individual must have memory issues or experience headaches, dizziness, lightheadedness, or blurry vision. Talk to your doctor to understand what may be causing your fatigue. 

Poor concentration and difficulty making decisions

Sleep disturbances and fatigue can manifest in difficulty focusing, which can make performing tasks challenging. For example, doing homework for school or completing an assignment for a job can seem impossible due to depression. The thoughts and feelings associated with this condition can distract and get in the way of completing tasks. 

Some individuals with depressive disorders may also exhibit poor decision-making skills or indecisiveness. Difficulty with decision-making may occur because the individual wants to avoid a negative outcome or anxiety, even if the topic is positive or beneficial. Risk aversion can also be a factor, and an individual with depressive symptoms may turn down a job promotion because they don’t believe they are competent or that there is hope for them. 

Thoughts of hopelessness and low self-esteem

In addition to having a depressed mood, those with dysthymic disorder may experience low self-esteem and thoughts of hopelessness consistently. Although these thoughts may not be as severe as they are in major depressive disorder, these symptoms can be a sign of suicidal thoughts, and they may worsen over time. 

If you are experiencing suicidal thoughts or urges, contact the National Suicide Prevention Lifeline at 988. Support is available 24/7.

Finding treatment as soon as possible can be crucial when experiencing long-term feelings of hopelessness. Engaging in therapy or beggining to take medications such as selective seretonin reuptake inhibitors, can help to reduce symptoms of persistent depressive disorder. With support, you may receive a boost of hope from someone else, which you can start reincorporating into your life. 

If you are experiencing suicidal thoughts or urges, call the 988 Suicide & Crisis Lifeline at 988 or text 988 to talk to a crisis provider over SMS. They are available 24/7 to offer support. 988 also offers an online chat for those with an internet connection.

Support options

Treating persistent depressive disorder can look similar to treating major depression, and it may consist of medication, therapy, or a combination of the two. Although you must have symptoms for at least two years to receive a diagnosis, you don’t need a diagnosis to seek support from a therapist. 

Selective serotonin reuptake inhibitors are the most common form of medication for various forms of depression, including chronic depression, persistent depressive disorder, and double depression. Selective serotonin reuptake inhibotors increase seretonin levels when they are deficient. This can bolster mood and decrease mental health symptoms. When combined with therapy, selective seretonin reuptake inhibitors can significantly decrease symptoms of depression. However, it’s important to speak to a healthcare professional before beginning antidepressants.

Some people with depression may avoid therapy due to barriers to in-person care, such as a high cost, transportation difficulties, or long distances. In these cases, online platforms like BetterHelp can offer convenient and affordable therapy. Through an online platform, individuals can get matched with a therapist within 48 hours. In addition, you can attend therapy from home and choose between phone, video, or live chat sessions. 

Studies show that online therapy is effective for those living with depression. One review of 17 studies found that internet-based interventions were more effective than face-to-face options in treating depression and improving quality of life, with results sustained in the long term. 

Takeaway

Although dysthymia is a chronic and persistent condition that can last a lifetime if untreated, the prognosis is often positive for those who receive support. To get started, it can be vital to recognize the signs of dysthymia and talk to a professional. Consider contacting a provider online or in your area to get started. With a therapist you can explore treatment options that can work for you, whether it’s beginning to take selective serotonin reuptake inhibitors, or maintaining weekly one-on-one appointments with your therapist. You’re not alone, and depression is highly treatable.
