During low dose experiences, trainees would also assist in a facilitation role. Dr. A reported being assessed as having “high potential” due to her prior experience with psilocybin, training as a psychologist, and Drug rehabilitation meditation practice. After the third retreat she reported mild anxiety, restlessness, concentration difficulty, and growing apprehension about participating in the 4th retreat. She asserted that at the 4th retreat she did not want to take mushrooms but described feeling pressured by both peer trainees and the leaders to proceed.

These symptoms can last for weeks, months, and sometimes even years. In some cases, the condition becomes chronic, while in other instances, people can suppress the feelings and function normally. The frequency of recurrence of perceptual distortions is lower for HPPD I than HPPD II 18. Prior substance users can voluntarily elicit or produce visual disturbances with or without known triggers 4,17,18.
About this article
She reported that in the weeks between the 4th and 5th retreat she experienced impaired concentration, difficulty sleeping, and significant anticipatory anxiety that she might have another challenging experience. During her high dose session, she described the experience as very intense. This session was ended abruptly by the leaders while she was still experiencing the psychoactive effects of psilocybin. She also noted a significant exacerbation of her chronic sciatic nerve pain during this time.
Hallucinogen Persisting Perception Disorder: Etiology, Clinical Features, and Therapeutic Perspectives
You’ll be aware of the effects of the disturbances, but you likely will not enjoy the other effects of reliving a trip. As the flashbacks become more common, they can become frustrating, even overwhelming. People living with post-traumatic stress disorder (PTSD) experience flashbacks of stressful, even painful situations.
- A representative, but not exhaustive, list of reported visual disturbances.
- They are written by UK doctors and based on research evidence, UK and European Guidelines.
- Because the visual episodes of HPPD can be unpredictable, you may want to prepare yourself with techniques for handling the symptoms when they do happen.
Dr. hppd symptoms A’s repeated monthly use of back-to-back, high-dose psilocybin-containing mushrooms is likely to be the prime causal factor for her psychological decompensation. High doses of psychedelics have been identified as a risk factor for adverse events in naturalistic studies on PAEs 13. Additionally, high frequency of use and back-to-back daily dosing has been identified as a potential risk factor in other case reports of psychedelic PAEs 14,15,16,17. These pharmacological considerations should be understood in the context of Dr. A’s immediate set and setting. Apprehensive, preoccupied, and confused mental states, consistent with Dr. A’s history, are known risk factors for challenging experiences and poor outcomes 18,19,20.
- Concomitant coexisting psychiatric disorders can represent a further clinical challenge, with the clinical construct of the lysergic psychoma as a possible heuristic model.
- The prevalence is low and it is more often diagnosed in those with a history of previous psychological issues or substance misuse, but it can arise in anyone, even after a single exposure to triggering drugs.
- When the person with HPPD experiences a flashback, loved ones can help them feel safe and remind them that symptoms are temporary.
People who take hallucinogens may be hoping to escape their lives, reset their brains or have new experiences. While the drugs may provide these benefits, they can also cause side effects, including hallucinogen persisting perception disorder or HPPD. Read on to learn more about this disorder and what can be done to treat it. The use of second-generation antipsychotics in HPPD patients without comorbid psychotic disorders is debated. Anderson recently reported the case of a young woman presenting prolonged and distressing multimodal pseudo-hallucinations, depressive symptoms, and anxiety, who was treated with Risperidone for three months without any significant improvement 48.
Hallucinogen Persisting Perception Disorder (HPPD)
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. The person who developed psilocybin-related HPPD combined the drug with marijuana — a drug that has some hallucinogenic properties. Marijuana and heavy alcohol use have triggered HPPD in some people who have a history of hallucinogen use. HPPD is a persistent, recurring disorder that distorts a person’s visual perception. The symptoms, which aren’t linked to another disorder, may persist for months or years.

Treatment
Clonazepam has been evaluated in three case reports and one open-label trial by Lerner 19,50,51. In the clinical trial, 16 HPPD patients were treated with a Clonazepam dosage of 2 mg/day 51. Their symptoms improved significantly after treatment initiation and the improvement persisted during a 6-month follow-up after treatment discontinuation 51. The same author reported two cases of cannabis-induced visual disturbances and correlated anxiety features.
