Help with co-occuring mental health issues


Mental health issues often don't occur alone. If you have two or more mental health conditions at the same time, we refer to it as comorbidity. What is comorbidity exactly and how do we treat it?

What is comorbidity

Definition & causes

What is comorbidity

Comorbidity literally means "the simultaneous occurrence of diseases." In this case, mental health conditions. For example, depression, anxiety, and one or more addictions. Depression, for instance, often goes hand in hand with anxiety. And those with an addiction often also have a mood disorder. This requires a special approach. U-center is an expert in treating double diagnoses or multiple problems.

Causes of comorbidity
Why do some combinations of mental health conditions occur frequently? For example, compare it to a car breakdown. If a car's headlights are less bright and the windshield wipers, the culprit may be then a broken generator. And that can be caused by a damaged V-belt. It works the same way with psychological comorbidity. Comorbid disorders either have the same cause or one problem causes the other. Unlike with a car, many mental health problems also affect each other reciprocally.

Comorbidity examples

Some mental health problems more commonly occur in combinations than others. Examples of common mental comorbidities are:

People dealing with depression often also have an anxiety disorder and vice versa. Both disorders often come from a negative self-image and damaged trust in others.

Addictions rarely occur alone. Of people with severe mental disorders, 41% also have an addiction or have dealt with addiction in the past. Among people without other severe mental disorders, this number is 19%. Schizophrenia, bipolar disorder (extreme mood swings), ADHD, and depression are also often combined with addictions. For example, biological factors can cause smaller amounts of alcohol or drugs to have greater consequences than for others. This leads to a faster dependence on the substance.

Comorbid PTSD is quite common. When you’ve experienced one or more very traumatic situations this can lead to mood disorders, anxiety disorders, and addictions. It can also develop into personality disorders, psychoses, and dissociative disorders. This is often because a trauma disrupts your ability to ‘manage yourself’ and causes a negative self-image. As a result, people with PTSD have an 80% greater chance of having one or more other mental disorders at the same time.

Autism often occurs combined with ADHD, depression, or an anxiety disorder. This is because autism and ADHD are partly caused by the same brain functions. This can cause you, for example, to be unable to assess certain situations well, making you feel anxious more quickly. And that can lead to depression overtime.

ADHD has a high comorbidity rate. Someone with comorbid ADHD, for example, may have depression, addiction, anxiety disorder, and/or bipolar disorder (extreme mood swings) at the same time. How does this happen? If you are easily distracted and impulsive, chances are your surroundings often respond negatively to this behaviour. This can cause you to think negatively about yourself and may turn into a depression in the long run. Alcohol or drugs can reduce restlessness or negative feelings in the short term. And the physical cause of ADHD and bipolar disorder is partially the same, which increase chances of suffering from this mental disorder when you have ADHD.

Age can also play a role in a comorbid disorder. More than half of people over 55 years old with a long-term mental illness have mental comorbidities. For those over 50 with an anxiety disorder or depression, more than half deal with two or more mental health issues.
This may be due to increasing physical discomfort or a decreasing social network.

Dealing with comorbidity?

How to recognize comorbidity

Recognizing comorbidity is not always easy. Either for yourself and not for healthcare providers. Our brains are much more complicated than, for example, the operating system of a car. For example, if you have been struggling with depression and anxiety for a long time, there may be a trauma or addiction behind it. That is why thorough research is always necessary if you are struggling on multiple fronts in your life.

How does U-center investigate comorbidity?
At U-center, we carefully investigate whether there is comorbidity. We also immediately check if our treatment approach matches your healthcare needs.

  • We discuss the best solution with you on the phone.
  • We examine the referral from your GP or psychiatrist.
  • We study your medical records from previous healthcare providers.
  • We ask you to fill out extensive questionnaires.
  • If we think U-center is right for you, we invite you for an intake interview online or in the clinic. If U-center is not (currently) the best option for you, we will help you to find a treatment that fits better.

If we still think U-center is right for you, we will start your treatment as soon as possible in our treatment centre.

Approch & treatment

Why does comorbidity require a special approach?

Suppose you have an alcohol addiction and depression and treat them separately. If the cause of these two is trauma, there is a good chance you will relapse. Without treating the trauma, you are unlikely to solve these problems. Furthermore, with multiple mental disorders, it is often unclear which disorder is causing your symptoms or how the disorders affect each other. That is why comorbidity requires an all-in-one approach.

Preventing relapse
In mental healthcare, many treatments are focused on specific disorders or treatment methods. For example, addiction clinics often do not treat depression and institutions for other mental health do not treat addiction. This makes it harder for people with multiple problems to find efficient therapy. Have you already visited different healthcare providers and tried different therapies? But are you not making sufficient progress? Then U-center is there for you.

At one point, I couldn't even get up on time and shower. My biggest challenge was leaving the house: meeting friends, studying... I thought my depression made me socially anxious, but it turned out to be the other way around.
