Hallucinogen persisting perception disorder (HPPD) signs include the presence of recurring visual disturbances after using a hallucinogen, such as LSD (lysergic acid diethylamide) or PCP (phencyclidine). Symptoms related to HPPD can have different possible causes, and therefore it is very crucial to rule out all possible underlying causes before diagnosing. Such was the course of action in our patient’s management described above. Some of the possible causes are anatomic brain lesions, brain infections (encephalitis), epilepsy, delirium, depersonalization, derealization, hallucinogen-induced psychotic mood and anxiety disorders, hypnopompic hallucinations, and schizophrenia 4. Some people get HPPD after using hallucinogenic drugs just once, while others may use them for years without https://ecosoberhouse.com/ any symptoms. Although it is unknown what proportion of those experiencing HPPD seek professional help, only a small group manages to procure the help they need.
How Can People With HPPD Disorder and Their Families Cope With the Condition?
Regardless, every perceptual symptom that was experienced during intoxication may re-occur following hallucinogen withdrawal. We report a list of the main literature-reported visual disturbances in Table 2. This may have biased the frequency of visual snow as patients with HPPD experiencing this symptom were more likely to be referred. Cases were collected retrospectively, meaning data for treatment outcomes were not available for all patients. All patients had their drug history recorded; however detailed timelines between use of illicit substance and onset of HPPD symptoms was not available.
- Lamotrigine has also been shown to reduce symptoms of depersonalization and derealization Sierra et al. 2001, although the same group was unable to reproduce their results in a placebo-controlled follow-up study Sierra et al. 2003.
- If you’re at work, you may consider designating a quiet, private place to wait for visual distortions to pass.
- The World Health Organization states it is among the top 10 diseases contributing to the global disease burden.
- These distortions can be particularly distressing, as they may interfere with normal functioning.
- She also used marijuana for relaxation and occasionally experimented with ecstasy, psilocybin mushrooms and ketamine.

- Only a small minority of the patients (12.3%) experienced HPPD symptoms for less than a month.
- The relationship between HPPD symptom type(s) and psychiatric comorbidity was varied.
- The clinical phenotype of HPPD presented in our paper shares overlapping features with visual snow syndrome (VSS) (Table 6).
- What sets HPPD apart is the re-experiencing of visual disturbances—often referred to as “flashbacks”—even when the individual is no longer under the influence of the drug.
- Hallucinogen-persisting perception disorder (HPPD), also known as acute hallucinogen-induced psychosis or informally known as “flashbacks,” is an unusual condition experienced by patients due to the use of different hallucinogenic substances.
- From Dr. Abraham’s observations, those who do recover from HPPD, do so within 5 years.
HPPD symptoms such as derealization and depersonalization might be exceptions to this tenet because of the narrowing of consciousness that characterizes these phenomena. Both substance-induced psychotic disorder and hallucinogen persisting perception disorder (HPPD) can involve visual disturbances and hallucinations. In substance-induced psychotic disorder, symptoms occur while the substance is still active in the body or during withdrawal.
Studies on Psychopharmacotherapy of HPPD
Symptoms can also include migraines, tinnitus (ringing in the ears), and difficulty reading. Here we present the case of Alcohol Use Disorder a 33-year-old female former LSD user who displayed typical symptoms of HPPD over an extended period of time. Both perceptual and affective disorder proved largely unresponsive to various psychopharmacological interventions. As part of the initial psychiatric assessment, extensive neuropsychological profiling was undertaken (Table 1). Memory functions, attention span, visuo construction and frontal-executive functions were examined.
Before the patient’s hospitalization, he reported having an eye exam within normal limits. As chief Clinical Officer at FHE Health, a nationally recognized behavioral health treatment provider, he ensures quality, innovation, and comprehensive treatment for patients. One theory is that taking hallucinogens changes the way the brain processes visual information, causing it to see things incorrectly or superimpose colors, patterns and images over things that exist in the environment. The hppd symptoms alterations in brain activity may be due to shifts in levels of the brain chemical gamma-aminobutyric acid or GABA. Because the condition affects only a small number of people, there’s much we don’t understand about HPPD.
