Hallucinogen Persisting Perception Disorder HPPD
Research suggests that up to 4% of hallucinogen users may experience HPPD. The condition is most frequently reported among young adults who use hallucinogens recreationally, though it can affect individuals of any age. The crucial movement towards a comprehensive clinical understanding of Hallucinogen Persisting Perception Spectrum Disorders (HPPSD) 23 is the establishment of an accepted operative nomenclature. This wide spectrum of disorders encompasses different subtypes, ranging from HPPD I to HPPD II, according to our hypothetical distinction.
Perceptual Distortions
Flashbacks may be triggered by an event or experience, or they may occur spontaneously. These symptoms may occur immediately after hallucinogen use and persist continuously. Or they may develop more than a year after hallucinogen use, fade and recur over time. Case reports by experts studying HPPD have revealed a large variety of symptoms. Some authoritative organizations refer to recurring flashbacks as HPPD. Halfway house One theory of why psychedelics cause visual hallucinations is that they stop information incoming into the visual cortex from being filtered out.
How to Deal With HPPD
To be included, cases had to meet DSM-5 HPPD diagnostic criteria (3). Due to diagnostic uncertainty, one patient was excluded, leaving 13 HPPD symptom cases for review. HPPD II aligns with the APA’s criteria for hallucinogen persisting perception disorder.
- Additionally, there are data supporting a neuroprotective effect Halonen et al. 2001.
- The mental disorder affects a small percentage of people with a history of psychedelic drug use.
- The psychedelic trip is likely caused by the way psychotropic compounds bind with 5-HT2A serotonin receptors.
- This drug is approved for use as an injectable, short-acting anesthetic and a nasal spray for depression.
How To Deal With HPPD Symptoms
- While the future of HPPD research remains unclear, general psychedelics research is going through something of a renaissance.
- An estimated 5.5 million adults in the United States use hallucinogenic drugs.
- The primary risk factor for HPPD disorder is using LSD and other hallucinogenic drugs.
- Secondly, HPPD seems to be more likely following the abuse of psychedelics, frequently occurring in a recreational context.
Additionally, individuals with traumatic brain injuries (TBIs) or other neurological conditions may face an increased risk, as these issues can impair the brain’s ability to process sensory information effectively. According to DSM-5, Hallucinogen Persisting Perception Disorder is the recurrence of perceptive disturbances that firstly develop during intoxication. The contents of the perception and visual imagery range extensively 17,19.
These factors will help your doctor reach a diagnosis and help you avoid possible complications from drug interactions. While these symptoms are reported, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) does not include them on the recognized list of symptoms. It is still unclear whether these symptoms are directly caused by the disorder. Researchers have recognized two forms of HPPD (type 1 and type 2). Type 1 HPPD https://ecosoberhouse.com/ is typically experienced as brief, random “flashbacks.” On the other hand, type 2 HPPD is generally long term, disturbing, and pervasive.

HPPD patients appear to be sensitive to first-generation antipsychotics at low doses, requiring monitoring of extrapyramidal side effects. Haloperidol 69 and Trifluoperazine 70 were reported to be helpful. Perphenazine (4–8 mg/day) 17,23, Sulpiride (50–100 mg/day) 23, and Zuclopenthixol (2–10 mg/day) 17,23, at very low doses, are well tolerated and may be an effective treatment. Some of the long-acting first-generation antipsychotics may still be useful in co-occurring Psychotic Spectrum Disorders and HPPD II 58. In one study, haloperidol was noted to reduce hallucinations, but an exacerbation of flashbacks in the early phases of treatment was highlighted as well 1,69. A dosage of 0.75 mg/die of Clonidine has been evaluated as a treatment option for nine HPPD patients 51,59 (Table 4).
