What is Low-Grade Depression and What You Can Do About It

Low-grade or mild depression can often go unnoticed since the symptoms tend to be mild and persist for long periods of time. While everyone has their emotional ups and downs, if you've been struggling with a consistently low mood, that could be a sign of low-grade depression.


What are the symptoms of low-grade depression?

Chronic low-grade depression is actually a symptom of a persistent depressive disorder, previously known as dysthymia or dysthymic disorder. It is one of the three major types of depressive disorders, alongside major depressive disorder and bipolar disorder. The symptoms of mild depression are very similar to the symptoms of major depressive disorder. The main difference is that low-grade depression is characterized by less severe symptoms which last for years without significant periods of wellness during that time.

According to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) the diagnosis of low-grade depression requires an adult to have been experiencing a depressed mood for at least two years. For children and adolescents, low-grade depression can be diagnosed if they have been experiencing either a depressed or irritable mood for at least one year. During that time, the symptoms must not be absent for more than two months. In addition to an ongoing depressed mood, you must also display at least two of the following symptoms:

  1. Poor appetite or overeating
  2. Insomnia or hypersomnia (sleeping too much)
  3. Low energy or fatigue
  4. Low self esteem
  5. Poor concentration or decision making
  6. Feelings of hopelessness

If you've noticed these signs, it is probably a good time to reach out to your doctor to talk about next steps.

What causes low-grade depression?

There are many different factors that could contribute to a low-grade depression, including genetics, environmental pressures, a biochemical imbalance, and prolonged stress. While the primary cause is unclear in many patients, people with low-grade depression may also have a chronic physical illness or another mood disorder. This makes it difficult to determine the cause of low-grade depression, but that doesn't mean that there aren't a variety of treatments to help you manage your symptoms.

How is the diagnosis made?

Your first step in finding out whether you have a form of depression is to reach out to your family doctor if you have one, or a telehealth service like Felix. As with other mood disorders, your doctor will assess the likelihood of the presence of low-grade depression based on the signs and symptoms that they can observe and that the patient reports. 

Your doctor will check your symptoms against the DSM-5 requirements for a diagnosis of low-grade depression. They will also consider the severity of your symptoms to determine whether it is more likely to be chronic low-grade depression or major depressive disorder, since the symptoms are very similar.

Your doctor may also suggest running some physical tests in order to rule out medical conditions like hypothyroidism, which can cause symptoms similar to those of mild depression. You may be asked about your medical history, medications, and family history of depression.

What are the treatment options for low-grade depression?

With such similar symptoms, it may not surprise you to learn that many of the same treatments are used for patients with low-grade depression and major depression. Depending on your situation, your doctor may prescribe antidepressant medication. SSRIs (selective serotonin reuptake inhibitors) are commonly prescribed for depressive disorders.

Psychotherapy or talk therapy is also one of the most common treatments for dysthymia. There are a number of different types of talk therapy, so you may have to try out a few therapists before you find one that feels like a good fit.

Another way to address depression symptoms is by practising self-care and taking a more proactive approach regarding your mental health. Here are some self-care ideas that could help you manage your low-grade depression.

Even if you and your doctor have developed a treatment plan to deal with your low-grade depression, it's possible that you may need to make adjustments at some point. Keep checking in and keeping track of your symptoms so that you and your doctor can find the best balance for your unique situation.
