The Intersection of OCD and Depression: What You Need to Know

One of the issues when dealing with mental health is that of co-occurring disorders, sometimes referred to as comorbid disorders. Comorbid simply means that two or more disorders are present at the same time. And comorbidity is common. Studies have found that having one mental health issue significantly increases the risk for the occurrence of a second or even a third disorder over time. 

OCD is no exception. It’s estimated that about  60% of people with OCD have one or more co-occurring mental health disorders including anxiety, depression, tic disorders, and obsessive compulsive-related disorders (OCRDs such as skin picking or trichotillomania). Research indicates that major depression (MDD) is the most common comorbidity, affecting about 50% of people with OCD. 

Living with Obsessive-Compulsive Disorder (OCD) is challenging on its own, but when it co-occurs with depression, the complexities and difficulties can intensify. Understanding the intersection of these two disorders can help you find effective ways to manage your symptoms. 

Understanding OCD and Depression

When you have two disorders, it’s important to understand the unique features of each one. 

Obsessive-Compulsive Disorder (OCD)

Obsessive Compulsive Disorder (OCD) is a mental health disorder characterized by the presence of intrusive thoughts, images, or urges, known as obsessions, which cause significant anxiety or distress. To alleviate this distress, individuals engage in repetitive behaviors or mental acts, known as compulsions. These symptoms can be severe, consuming a significant portion of a person’s time and attention, and causing marked emotional distress and impaired functioning. 

• Obsessions: Intrusive and distressing thoughts, images, or urges. Common themes include contamination fears, harm fears, symmetry and order, and taboo thoughts.
• Compulsions: Repetitive behaviors or mental acts performed to neutralize the obsessions. Examples include excessive hand washing, checking, counting, and arranging.

Depression

Depression is a mood disorder that involves persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in activities. It can significantly impair daily functioning and one’s quality of life. 

Symptoms of depression can include:

• Depressed mood
• Loss of interest or pleasure (anhedonia)
• Changes in appetite or weight
• Sleep disturbances
• Fatigue
• Feelings of worthlessness or guilt
• Difficulty concentrating
• Thoughts of death or suicide

Comorbid OCD and Depression

When OCD and depression occur together, they can create a vicious cycle. The distress and impairment caused by OCD can lead to feelings of hopelessness and sadness, contributing to depression. In fact, research suggests that for many people living with OCD, the OCD tends to predate the onset of depression. 

Conversely, depression can exacerbate OCD symptoms. Studies have found that people who have OCD and depression tend to have more severe OCD symptoms and more severe general pathology.  Depression can decrease motivation to engage in treatment or cope with obsessions and compulsions. Additionally, people with comorbid OCD and depression usually present with more severe anxiety symptoms, less insight about their OCD, greater impairment in functioning, and an elevated risk of suicide attempts when compared with people with OCD without depression.

The combination of OCD and depression can make treatment more challenging too. People who have both OCD and depression may not respond as well to the standard treatments for either disorder. For example, cognitive-behavioral therapy (CBT), the gold standard for OCD, may be less effective if the individual's depression is not addressed concurrently.

Treating Comorbid OCD and Depression

When considering treatment for comorbid disorders, it’s important to choose a plan that will address the symptoms of both disorders. Some research has found that focusing primarily on OCD often improves depressive symptoms. Treating depression first does not seem to have the same effect on OCD. 

Treating OCD and depression means taking an integrated approach. What that looks like will vary from person to person and which approach to use is best determined in consultation with your mental health provider. 

Integrated Cognitive Behavioral Therapy (CBT)

Exposure and Response Prevention (ERP)

ERP, a specialized form of cognitive behavioral therapy (CBT), is widely considered the gold standard for treating OCD. ERP involves gradually exposing the individual to the source of their anxiety (the obsession) and preventing the compulsive behavior that usually follows. Over time, this helps to reduce the anxiety associated with the obsession and the urge to engage in the compulsion.

Cognitive Restructuring

Cognitive restructuring, an essential component of CBT, helps the person identify and challenge negative thought patterns that contribute to their depression and OCD. Cognitive restructuring consists of:

1. Identifying Negative Thoughts: Learning to notice negative or irrational thoughts related to both OCD and depression.
2. Examining Evidence: Evaluating the evidence for and against these thoughts. Are they true or not true?
3. Reframing Thoughts: Learning to replace irrational or negative thoughts with ones that are more balanced and realistic.

Medication

Medications can be an effective component of treatment for comorbid OCD and depression. Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed for both conditions and can help reduce symptoms of both OCD and depression. These medications can help reduce the severity of symptoms by increasing levels of serotonin in the brain, which is believed to play a role in mood regulation. In some cases, other medications may be considered.

What Else Can You Do?

Beyond clinical interventions like therapy and medication, there are a number of things you can do to help manage your symptoms and support your well-being. 

Lifestyle Practices

incorporating healthy lifestyle practices can support your overall mental health and enhance the effectiveness of other treatments. Here are some lifestyle changes you can implement:

• Regular Exercise - Physical activity releases endorphins, which can improve mood and reduce anxiety. Incorporating “exercise snacks”, brief bouts of exercise like a short walk at lunch, can help you easily incorporate movement into your day.
• Healthy Diet – They say food is medicine and a healthy, balanced diet has been shown to positively impact mood and energy levels. 
• Sleep - Sleep helps the brain function at its best. Poor sleep has been consistently linked to physical and emotional problems and can exacerbate mental health conditions. Practice good sleep hygiene by setting a regular sleep schedule and creating a calming bedtime routine. 

Find Support

Building a strong support network can provide emotional and practical support for managing comorbid OCD and depression. A support network might include: 

• Family and Friends – Seek out supportive friends and family. Educate them about your experience and how they can support you. Open communication can help them understand your struggles and provide the support you need.
• Support Groups – A support group, whether online or in person, can connect you with others who are on a similar path. Sharing your experiences and learning from others can provide validation and be a source for finding practical strategies.

Self-Help Strategies 

Self-help strategies can be beneficial in managing comorbid OCD and depression too. F

• Mindfulness and Meditation - Practicing mindfulness and meditation can help you stay present and reduce the power of obsessive thoughts and depressive rumination.
• Journaling - Writing about your thoughts and feelings can help you process emotions and identify patterns of thoughts, feelings, and behaviors. Try to set aside a few minutes each day to write and reflect. 
• Practice Gratitude – Gratitude is the practice of intentionally appreciating the things in your life that are valuable or meaningful to you. Practicing gratitude has been liked to improved sense of well-being and improvements in mental health. And practicing gratitude is easy. Take a few moments daily to focus on positive aspects of your day and appreciate even the small moments of joy.

Putting It Together

Living with comorbid OCD and depression presents unique challenges, but with the right combination of treatments and support, individuals can manage their symptoms and improve their quality of life. Integrated cognitive-behavioral therapy, medication, lifestyle modifications, and strong support networks are all crucial components of effective treatment. By addressing both conditions simultaneously and employing a multifaceted approach, individuals can find relief and work towards recovery.
