Research has indicated a potential correlation between HPPD and other mental health conditions. Conditions such as anxiety disorders, depression, and substance use disorders may co-occur with HPPD. It is crucial for healthcare providers to conduct a thorough evaluation to Alcoholics Anonymous identify and address any additional underlying conditions that may require specific treatment approaches. Hallucinogenic persisting perception disorder is characterized by the recurrence of visual phenomena caused by psychedelic drugs for days, months, or even years after the trip.
- Because HPPD is relatively under-reported and under-researched, we still don’t know a huge deal about HPPD.
- Usually, people experience symptoms affecting their vision or mood.
- Hallucinogen-persisting perception disorder (HPPD) causes a person to keep reliving the visual element of an experience caused by hallucinogenic drugs.
- This means that a person with HPPD just has visual disturbances, such as seeing blurry patterns, size distortion, and bright circles.

Also known as LSD, this drug is a clear or white material derived from a fungus that grows on grains. It causes people to see images and feel sensations that aren’t real, called hallucinations. However, visual disturbances defined as HPPD also occur in people who have never used psychedelics or other drugs, especially those with anxiety disorders. HPPD symptoms can also manifest months or years after psychedelic use, throwing into question the causal link between the drug and the visual disturbances. Hallucinogen persisting perception disorder (HPPD) signs include hppd symptoms the presence of recurring visual disturbances after using a hallucinogen, such as LSD (lysergic acid diethylamide) or PCP (phencyclidine).
- A healthcare provider diagnoses HPPD based on assessment tools and by ruling out other health conditions.
- The Neurosensory Research Foundation14 was founded by HPPD sufferers to promote research and awareness around the condition.
- It’s unclear how many people experience this condition because people with a history of recreational drug use may not feel comfortable admitting this to their doctor.
- A person fearful of having acquired HPPD may be much more conscious about any visual disturbance, including those that are normal.
Signs of Hallucinogen Persisting Perception Disorder (HPPD)
Your doctor may give you an electroencephalogram (EEG) test, to look at your brain’s electrical activity. HPPD is different from other psychotic disorders because while you’re having an episode, you’re aware of it, and you know that what you’re seeing isn’t real. A flashback feels as if the individual is relieving something that happened in the past. 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.
- It is important to be open and honest about any past drug use, to help the doctor reach the correct diagnosis.
- The hallucinations are typically long, and can come and go over the course of months or years.
- The brains of people with HPPD may be unable to filter unnecessary signals, causing visual distortions, according to a 2018 article in the journal Brain Sciences.
Symptoms Reported by DSM V
LSD is a lab-made chemical that is in a class of drugs called psychedelics. In its pure state, it’s a white crystalline substance, but you only need a very small amount to feel the effects. People typically take the drug in sugar cubes or on small gelatin sheets that dissolve on the tongue. However, in people with HPPD, symptoms seem typically to be worse, but complication comes from the additional roles played by anxiety and fixation. Indeed, anxiety has been implicated in visual perceptual effects similar to HPPD,17 and authors have recognized the crucial role of attending to underlying anxiety and panic in recovering from the disorder. HPPD can occur in combination with other mental disorders, such as panic disorder, alcohol use disorder, and depression, according to the DSM-5.
Hallucinogen Persisting Perception Disorder (HPPD)
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. Many people feel that HPPD is just another myth created by the (failed) War on Drugs.
In addition, visual problems can be caused by brain infections or lesions, epilepsy, and a number of mental disorders (e.g., anxiety, delirium, dementia, schizophrenia, Parkinson’s disease). For an individual to be diagnosed with HPPD, these other potential causes must be ruled out. With HPPD a person experiences ongoing visual disturbances, flashbacks, and other persistent symptoms after hallucinogenic drug use. Little research explains what causes HPPD, but certain factors can increase your risk. HPPD II aligns with the APA’s criteria for hallucinogen persisting perception disorder.
