What Is Depersonalization-Derealization Disorder?

Written by Medicover Team and Medically Reviewed by Dr Siva Anoop Yella , Psychiatrist

Feeling disconnected from your own mind or the world around you can be deeply unsettling. In depersonalization-derealization disorder (DDD), this experience happens often and can last for a long time. You may feel like you're watching your life from outside your body or seeing your surroundings through a foggy lens.

This disorder involves two main parts depersonalization, where you feel detached from yourself, and derealization, where the environment seems unreal. Even though these episodes feel strange or scary, people with DDD still know what's real. This awareness makes the condition more frustrating and stressful.

How Common is Depersonalization-Derealization Disorder?

Many people experience short moments of disconnection during high stress. But in DDD, the symptoms are chronic or keep coming back. This condition affects about 1 to 2% of people worldwide, often starting in teens or early adulthood.

It's more common than most people realise, but it often goes undiagnosed due to a lack of awareness or misunderstanding of the symptoms. Getting the right support early makes a big difference.

What Are the Symptoms of Depersonalization and Derealization?

People with DDD often struggle to explain how they feel. The symptoms can sound confusing to others but are very real and distressing to those experiencing them.

You may feel

As if you're outside your body, watching yourself move or speak.
Like your thoughts or feelings don't belong to you.
As if you're in a dream, or the world feels flat, lifeless, or artificial. Emotionally numb or robotic.
That time is moving too fast or too slowly.
A strong sense that you're losing control or going crazy, though you're not.
These feelings can come and go, last for hours or even longer, and may feel more intense during stress or tiredness.

What Causes Depersonalization-Derealization Disorder?

DDD doesn't have a single known cause, but it's often triggered by severe stress, emotional trauma, or frightening experiences. In many cases, the mind creates a sense of detachment to cope with overwhelming emotions.

Possible causes include

Childhood trauma or abuse
Sudden loss of a loved one
Witnessing or experiencing violence
Life-threatening events like car crashes or natural disasters

It may also develop from other mental health issues such as anxiety, panic attacks, PTSD, or depression. Some cases have been linked to epilepsy or other neurological conditions.

Who is at Risk for Developing DDD?

Some people may be more likely to develop DDD due to their personality or medical background. It's not always clear why one person develops it and another doesn't after a similar event.

Risk factors include

Ongoing or past trauma
High levels of stress or anxiety
Family history of dissociative disorders
Low emotional awareness
Use of recreational drugs (especially hallucinogens)
Neurological conditions such as seizures

Being aware of these risks can help in recognizing the disorder early and seeking proper care.

How is Depersonalization-Derealization Disorder Diagnosed?

There is no single test for DDD. Diagnosis is based on a detailed conversation about symptoms, mental health history, and current functioning. Doctors may also rule out other medical causes.

Diagnosis steps often include

Psychological evaluation
Screening for anxiety, depression, or PTSD
Questions about drug or medication use
Sometimes a physical exam or neurological testing

It's important to be honest about how you feel, even if it seems hard to explain. The right words help your doctor understand what you're going through.

Are Any Tests Used to Confirm the Diagnosis?

While there's no lab test to prove DDD, your doctor may use questionnaires to track your symptoms and their impact on daily life. In some cases, brain scans or EEGs are done to check for physical conditions like seizures.

If symptoms are not caused by another illness or medication, and you still feel a strong sense of disconnection, DDD may be the diagnosis.

What is the Best Treatment for Depersonalization-Derealization Disorder?

Treatment for DDD is focused on managing the symptoms and helping you feel grounded again. Many people improve with therapy, stress-reduction techniques, and sometimes medication.

The most effective treatments include

Cognitive Behavioral Therapy (CBT): Helps change how you think about your symptoms and manage triggers.
Trauma-focused therapy: Useful if past trauma caused the disorder.
Mindfulness and grounding exercises: Bring awareness back to the present moment.
Medication: Antidepressants or anti-anxiety meds may be used in some cases.

Each treatment plan is different and depends on your symptoms, history, and goals.

What Medications Are Used in Treatment?

While talk therapy is the main form of treatment, medications may help when DDD comes with depression or anxiety.

Doctors may prescribe

SSRIs (like fluoxetine or sertraline)
Anti-anxiety meds (for short-term use)
Mood stabilizers
Antipsychotics (used cautiously)

Medication alone usually isn't enough it works best alongside therapy and lifestyle changes.

When Should You See a Doctor for Depersonalization or Derealization?

Feeling detached from yourself or the world around you can be scary. If these feelings last more than a few days or start to affect your daily life, it's time to get help. You are not alone, and the right care can make a big difference.

See a doctor if you

Feel like you're outside your body or watching life from afar
Notice the world feels strange, blurry, or dreamlike often
Struggle to focus, work, or keep up with daily routines
Feel anxious, confused, or afraid because of these symptoms
Had a traumatic experience before these feelings started

The sooner you get support, the sooner you can start feeling like yourself again. Early care helps prevent symptoms from becoming worse or long-lasting.

Your health is everything - prioritize your well-being today.

What is the Outlook for People With DDD?

Many people recover fully, especially with early and consistent treatment. For others, the disorder may come and go over time, but symptoms often improve as coping skills develop.

Without treatment, DDD can last for months or years and interfere with relationships, school, or work. But with support, most people find relief and feel more in control.

How Long Does It Take to Recover from DDD?

Recovery time varies. Some people feel better in weeks, while others take months. Progress may be slow, but small improvements build up over time.

Consistency is key regular therapy sessions, self-care, and stress management all play a role. Even during setbacks, the path forward is possible with patience and the right support.

Take deep breaths or touch nearby objects to feel calm.
Try to sleep at the same time every night.
Stay away from alcohol and drugs.
Talk to your friends and family often.
