One is the Vividness of Visual Imagery Questionnaire (VVIQ), a scale that evaluates visual imagery by asking questions about vivid memories and discussing experiences as they are seen visually. Another is the Modified Tellegen Absorption Scale (MTAS), which assesses how open a person is to absorption, a personality trait that represents being prone to accepting fantasy as real. Lastly, the Visual Apophenia Luke Irvine Scale (VALIS) https://ecosoberhouse.com/ for HPPD uses cloud images to determine if people see images within the clouds and, if so, how vividly. The flashbacks of HPPD are primarily visual and can make you feel as if you are reliving an experience from the past.
Treatment for HPPD
In conclusion, Hallucinogen Persisting Perception Disorder (HPPD) is a rare condition characterized by persistent visual disturbances following the use of hallucinogenic substances. The symptoms of HPPD can range from visual snow and geometric patterns to depersonalization and difficulty with night vision. While there is no known cure for HPPD, various treatment options, including psychotherapy, medication, and lifestyle modifications, can help individuals manage the symptoms and improve their quality of life. The patient developed and reported several hallucinogen-induced perceptual symptoms for the first time after seven months of complete cessation of LSD. His symptoms affected enough of his social, professional, and other areas of functioning to be admitted to the hospital. However, Criteria C of the DSM-5 could not be met due to the patient’s history of schizophrenia.
Simple changes to daily habits can help manage HPPD symptoms. These include:
On the ninth, tenth, and eleventh days, the same regimen continued with the improvement of an elevated mood of 6/10. The patient believed that the medications were finally working for him. He denied any intrusive thoughts or auditory or visual hallucinations. Hallucinogen-persisting perception disorder (HPPD) causes a person to keep reliving the visual element of an experience caused by hallucinogenic drugs.
- Individuals experience time- and space-related perceptual distortions.
- Some individuals may have a predisposition to developing HPPD due to their unique neurobiology or genetic makeup.
- Lauterbach et al. reported the unique case of HPPD induced by the atypical antipsychotic Risperidone 60.

Trails or tracers, or when the image of objects seem to linger even after they move, creating a repeated “trail” of the object as it moves. Or you may continue to see an object even after it’s gone from your vision (an “after image”). As researchers come to understand more about the condition, a more extensive range of treatments may become available. HPPD does not cause people to have full hallucinations or delusions. Worrying about having an HPPD episode could actually make you more likely to experience one.
- The rationale behind this interesting and novel approach is that improving sensory gating by dopaminergic enhancers may cause an inhibition of catechol-O-methyl transferase (COMT), that may improve HPPD symptomatology.
- The exact cause of HPPD is not fully understood, and researchers continue to search for a definitive answer.
- The causes of hallucinogen persisting perception disorder are incompletely understood.
Some people report episodes of HPPD (type 1) as pleasant, like a “free trip” where they get the good feelings of a hallucinogen without taking a alcoholism treatment drug. But more commonly, episodes of both types cause feelings of distress and anxiety. Other common symptoms include anxiety, panic attacks, and depersonalization.
The way the flashbacks in HPPD affect a person’s vision can be frustrating and may cause anxiety. If you’ve used hallucinogenic drugs, you should let your doctor know. It’s important to understand that your doctor’s primary concern will be helping you address and treat your symptoms. HPPD is divided into two types, according to the kinds of hallucinations the person HPPD symptom experiences.
Flashbacks are typically less intense and do not last as long as the effects you get when using hallucinogens. You may feel a dissociation or depersonalization from your situation during the flashback. Treatment may not lead to complete recovery, and patients, especially those with Type II, must learn to cope with the visual disturbances. In many accounts, accepting the visual phenomena helps patients learn to ignore them.
What Is Hallucinogen Persisting Perception Disorder (HPPD)?
Other people use these drugs for many years before experiencing symptoms. The number of people with HPPD is low, and it’s more often diagnosed in those with a history of previous psychological issues or substance use. However, it can arise in anyone, even after a single exposure to triggering drugs.
The duration of HPPD varied from less than one year to over 10 years. It is important to note that individuals with HPPD may experience a combination of these symptoms, which can persist for an extended period. The severity of symptoms can vary from mild and tolerable to severe and significantly impairing. However, modern research into HPPD highlights the distinction between these previously named “flashbacks” and Hallucinogen Persisting Perception Disorder (HPPD) itself. While flashbacks are temporary and transient experiences, HPPD is a lifelong condition that sufferers live with continuously.
