Key points

  • DPDR involves persistent feelings of being detached from your body or the world around you.
  • It is often a response to severe stress, anxiety, or previous traumatic experiences.
  • Symptoms can be distressing but are not a sign of 'losing your mind' or psychosis.
  • Diagnosis in the UK usually involves a GP consultation to rule out other medical causes.
  • Treatment focuses on psychotherapy, particularly CBT, and managing underlying anxiety.
  • Online GPs can provide initial assessments and referrals for specialist mental health support.

What is Depersonalisation-Derealisation Disorder?

Depersonalisation-Derealisation Disorder (DPDR) is a dissociative condition where an individual regularly feels detached from themselves or their surroundings. While many people experience brief moments of dissociation during highly stressful events, those with DPDR experience these sensations persistently or recurrently, which can significantly impact daily life.

In the UK, it is increasingly recognised that these symptoms are often linked to chronic anxiety or past trauma. It is important to understand that DPDR is not a form of psychosis; individuals remain aware that their perceptions are distorted, which often adds to the distress of the condition.

The Difference Between Depersonalisation and Derealisation

  • Depersonalisation: Feeling like an outside observer of your own thoughts, body, or movements. You may feel like a 'robot' or that your limbs are not your own.
  • Derealisation: Feeling that the world around you is unreal, 'foggy', or like a movie set. Objects might look 'flat' or distorted in size.

Common Symptoms and Experiences

The symptoms of DPDR can be difficult to describe to others, often leading patients to fear they are 'going mad.' However, clinical evidence shows these are protective mechanisms of the brain during periods of overwhelm. Common experiences reported by British patients include:

  • A sense of being in a dream or a fog.
  • Feeling emotionally numb or disconnected from memories.
  • Visual distortions, such as a lack of depth perception or heightened sensitivity to light.
  • The sensation that you are 'auto-piloting' through your day without actually being present.
  • Constant 'checking' of your mental state to see if you still feel unreal.

If these symptoms persist for several weeks or keep returning, it is advisable to seek medical advice to help manage the distress they cause.

What Causes Dissociation and DPDR?

According to NHS and NICE guidance, dissociation is often the brain’s way of coping with too much stress. When the nervous system is overwhelmed, it can 'disconnect' as a survival strategy. Potential triggers include:

Severe Stress and Anxiety

High levels of cortisol and adrenaline from Generalised Anxiety Disorder (GAD) or Panic Disorder can trigger dissociative episodes. The brain attempts to shut down emotional processing to protect itself.

Trauma

Many individuals with DPDR have a history of childhood emotional neglect, abuse, or a single traumatic event. The mind uses dissociation as a shield against painful emotions.

Recreational Drug Use

In some cases, DPDR can be triggered by a bad reaction to drugs, particularly cannabis or hallucinogens. Even after the drug has left the system, the resulting anxiety can keep the 'unreal' feeling alive.

Diagnosis and Treatment in the UK

The first step toward recovery is a formal assessment. A UK GP will typically ask questions about your mood, any medications you are taking, and your history of stress. They may perform blood tests to rule out physical causes like thyroid issues or vitamin deficiencies.

Psychological Therapies

Cognitive Behavioural Therapy (CBT) is often the first line of treatment. It focuses on reducing the fear of the symptoms themselves. When you stop fearing the 'unreal' feeling, the anxiety levels drop, allowing the dissociation to naturally fade.

Grounding Techniques

NHS practitioners often recommend grounding exercises to help 'pull' you back into your body. This includes the '5-4-3-2-1' technique (noticing five things you can see, four you can touch, etc.) or using strong sensory input like holding an ice cube.

Medication

There is no specific 'DPDR pill,' but if your symptoms are driven by depression or anxiety, a GP may prescribe SSRIs (Selective Serotonin Reuptake Inhibitors) to help stabilise your mood.

When to Speak to an Online Doctor

Discussing mental health can be daunting, and for those experiencing DPDR, leaving the house can sometimes feel overwhelming. Speaking to a GP online provides a calm, familiar environment to discuss your symptoms.

An online doctor can help by:

  • Explaining the mechanism of dissociation to reduce your fear.
  • Conducting an initial screening for anxiety and depression.
  • Discussing treatment options and self-help strategies.
  • Providing a private referral to a specialist psychiatrist or psychotherapist if needed.
  • Issuing fit notes if your symptoms are temporarily affecting your ability to work.

Through OnlineDoctor24, you can book a consultation to speak with a GMC-registered GP who can help you navigate the next steps in your mental health journey.

Managing DPDR: Self-Help Strategies

While professional help is vital, there are steps you can take daily to manage the sensations of unreality:

  • Stop 'Body Checking': Constantly monitoring your thoughts to see if you feel 'normal' actually keeps the brain in a state of high alert. Try to focus on external tasks.
  • Maintain Routine: Keeping a regular sleep and meal schedule helps stabilise the nervous system.
  • Limit Caffeine: Stimulants can increase the physiological symptoms of anxiety, which in turn triggers dissociation.
  • Accept the Feeling: This sounds counterintuitive, but telling yourself 'I feel unreal right now, but I am safe' can reduce the panic that fuels the condition.

Red flags — when to seek urgent help

Call 999 or go to A&E if you experience any of the following:

  • Symptoms accompanied by a sudden, severe headache or loss of consciousness.
  • If you feel you are an immediate danger to yourself or others.
