What causes derealization

What is Derealization?

Derealization is a fascinating and often unsettling psychological phenomenon characterized by a sense of detachment from one's surroundings. Individuals experiencing derealization may feel as though the world around them is not real, is artificial, or is like a dream or fog. This experience is distinct from hallucinations, where one perceives things that aren't there; instead, it's a distortion of one's perception of reality itself. It's a type of dissociative symptom, a defense mechanism the mind might employ when overwhelmed.

Common Causes and Triggers

The exact causes of derealization are not fully understood, but it is widely believed to be a response to significant stress, emotional trauma, or overwhelming anxiety. The brain, in an attempt to cope with unbearable psychological pain or fear, may disconnect the individual from their immediate reality. This detachment can serve as a protective buffer, making the overwhelming experience feel less direct or impactful.

Psychological Factors:

• Stress and Trauma: Severe stress, whether acute (like a car accident) or chronic (like ongoing abuse or neglect), is a primary trigger. Post-traumatic stress disorder (PTSD) frequently involves derealization symptoms.
• Anxiety Disorders: Conditions such as generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder are strongly associated with derealization. Panic attacks, in particular, often include feelings of unreality.
• Depression: While not as common a primary symptom as in anxiety, depression can also manifest with derealization, especially in more severe forms.
• Depersonalization: Derealization often co-occurs with depersonalization, a feeling of being detached from one's own body or self. The two are often grouped together as depersonalization-derealization disorder.

Physiological and Medical Factors:

• Substance Use: Certain drugs, including hallucinogens (LSD, psilocybin), cannabis, and MDMA, can induce derealization during intoxication or even lead to persistent symptoms (hallucinogen persisting perception disorder - HPPD). Withdrawal from certain substances can also be a trigger.
• Neurological Conditions: Migraines, particularly those with aura, and certain types of epilepsy (like temporal lobe epilepsy) can sometimes present with derealization as a symptom. Brain injuries can also be a cause.
• Sleep Deprivation: Profound lack of sleep can impair cognitive function and perception, leading to transient feelings of unreality.
• Fatigue: Extreme physical or mental exhaustion can lower the threshold for experiencing dissociative symptoms.
• Medical Illnesses: While less common, certain severe physical illnesses or conditions affecting brain chemistry can contribute.

How Derealization Manifests

The experience of derealization can vary greatly among individuals. Common descriptions include:

• The world appearing foggy, dreamlike, or artificial.
• Objects seeming distorted in size, shape, or distance.
• Sounds appearing muffled or distant.
• A feeling of emotional detachment from loved ones or familiar places.
• A sense of observing oneself or the world from behind a glass or veil.
• Time distortion, where time seems to speed up or slow down.

It's crucial to differentiate derealization from psychosis. While both involve altered perceptions, psychosis typically involves delusions or hallucinations, whereas derealization involves a distortion of perceived reality while maintaining insight that the perception is distorted.

When to Seek Help

Occasional, brief episodes of derealization triggered by extreme stress might not require medical intervention. However, if derealization is persistent, recurrent, distressing, or significantly interferes with daily functioning, it is important to consult a healthcare professional. A doctor can help rule out underlying medical conditions and refer you to a mental health specialist for appropriate diagnosis and treatment, which often involves psychotherapy and, in some cases, medication.
