Evaluation Scale for Depersonalization-Derealization Disorder (DPDR)
Depersonalization-Derealization Disorder (DPDR) is a dissociative condition that can disrupt daily life due to frequent feelings of detachment from one's body and a dreamlike quality that makes the external environment seem unreal.
First described by the American neurologist C. W. Lippman in 1952, DPDR is not a psychotic disorder as people with DPDR are aware that their feelings aren't real. Symptoms of depersonalization include the sensation of watching oneself, bodily sensations feeling distant, loss of control over speech or movements, numbness, and the perception that memories may not be one's own. Symptoms of derealization, on the other hand, include feeling like one is living in a dream or movie, people around seeming unreal, time feeling unreal, distorted or hard-to-estimate object sizes and shapes, blurry or colorless surroundings, flat or two-dimensional surroundings, and surroundings appearing sharper and clearer than usual.
It's important to note that DPDR can be caused by various factors such as traumatic events, lack of sleep, hallucinogenic drugs, seizure disorders, brain diseases, or symptoms of dementia. It can also be linked to certain external factors, including these conditions.
This brief questionnaire is designed for anyone who thinks they may be experiencing symptoms of DPDR. It can be used as a self-screening tool to help determine whether or not it is advisable to seek professional help for one's symptoms. However, it's crucial to remember that an individual cannot self-diagnose DPDR. A trained medical professional is required for diagnosing DPDR or creating a plan to alleviate symptoms.
The test can help determine whether one may need additional help and professional support for their symptoms. If symptoms of DPDR are disrupting your daily life, it's advisable to seek professional help. The results of this questionnaire can provide valuable insights for both the individual and the healthcare provider in understanding and addressing the symptoms.
Some people with DPDR have no discernible reason for developing the condition, making it all the more important to seek help if symptoms persist. If you're experiencing any of these symptoms, remember that you're not alone, and help is available. Reach out to a healthcare provider to discuss your concerns and begin the journey towards understanding and managing your symptoms.
