Flashbacks are a feeling that you’re reliving an experience from your past. During some flashbacks, the sensation of reliving the trip or the effects of the drug is pleasant. HPPD II – The prognosis is usually worse than in HPPD I. Some patients fail to adapt to the presence of these long-lasting, recurrent visual and sensory disturbances1118. There is a consistent subgroup within those patients with HPPD II that require constant pharmacologic intervention1118.

Therapy can help people with the disorder learn to manage stress and develop coping strategies for dealing with HPPD vision symptoms. 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. After HPPD II onset, hallucinogenic events tend to occur https://ecosoberhouse.com/article/hallucinogen-persisting-perception-disorder-hppd-symptoms/ more frequently, and their duration and intensity increase. 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 drug. But more commonly, episodes of both types cause feelings of distress and anxiety.
Treatments
A person fearful of having acquired HPPD may be much more conscious about any visual disturbance, including those that are normal. 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 marijuana addiction be diagnosed with HPPD, these other potential causes must be ruled out.

Research is limited regarding the best treatment but prescription medications and relaxation techniques, such as meditation, breathing, and yoga, may reduce symptoms or shorten episodes. However, taking certain medications can worsen symptoms in some people. Maintaining close contact with a healthcare provider when determining an effective treatment plan is important. The Perception Restoration Foundation (PRF) is an industry-funded 501 nonprofit.
On the other hand, a more recent study has shown the ineffectiveness of antipsychotic medications in an SCZ+HPPD population 57. The unifying symptomatology of all cases of HPPD (Types I/II) are a wide range visual disturbances. These include, but are certainly not limited to micropsia, macropsia, floaters, fractals, monochromatic vision, acquired dyslexia, visual snow, and other strange visual perceptions13. Other, non-visual symptoms can include recurrent synesthesias, dissociation, auras, depersonalization, and derealization3. Accompanying these hallucinations and sensory disturbances, the patient may report severe anxiety, which can escalate to full blown panic attacks1.
- Therapy can be an important part of hallucinogen persisting perception disorder (HPPD) management, and online therapy offers a flexible and comfortable way to receive treatment.
- This theory could also explain why sometimes HPPD can be resolved or decreased by having another psychedelic experience.
- The psychedelic trip is likely caused by the way psychotropic compounds bind with 5-HT2A serotonin receptors.
- When abused, it causes hallucinations and disconnection from reality.
- There is also a correlation between the number of times a hallucinogenic drug is used and the onset of HPPD.
Other disorders with similar symptoms
These flashbacks are rarely as intense or long lasting as a typical drug-induced trip. 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. Most people who experience HPPD only have symptoms for a short time after drug use.
- Haloperidol 69 and Trifluoperazine 70 were reported to be helpful.
- Previous use of hallucinogens is necessary, but not sufficient, for diagnosis of HPPD, and the symptoms cannot be due to another medical condition.
- Functional neuroimaging may be beneficial in localizing a specific target for stimulation and may prevent wasting time and money on targets which are not as likely to be involved in the pathogenesis.
- In HPPD, the filtering mechanism may remain switched off even after the drug has worn off.
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. Researchers and doctors do not yet have a solid understanding of who develops HPPD and why. The strongest connection points to a history of hallucinogenic drug use, but it’s not clear how the type of drug or the frequency of drug use may affect who develops HPPD.
