Flashbacks are common in people with posttraumatic stress disorder (PTSD). In PTSD, the flashbacks take over many of your senses at once and enhance your feeling of being in the past. Studies show marijuana – specifically THC, the chemical in marijuana responsible for its mind-altering effects – is the most commonly reported drug people with HPPD used in the past. A representative, but not exhaustive, list of reported visual disturbances. In some cases, people experience HPPD after their very first use of a drug. Other people use these drugs for many years before experiencing symptoms.
- In PTSD, the flashbacks take over many of your senses at once and enhance your feeling of being in the past.
- You’ll be aware of the effects of the disturbances, but you likely will not enjoy the other effects of reliving a trip.
- With HPPD, you re-experience the visual aspects of a drug trip, even though you haven’t taken any kind of substance in months or even years.
- Agomelatine, given its peculiar function on neurotrophic factors 74, could have some benefits on the syndrome, although no data are available until now.
- It has been suggested that brain stimulation treatments, such as Repetitive Transcranial Magnetic Stimulation (rTMS), may be effective in treating HPPD, but there has been little evidence as of yet to establish their efficacy.
Hallucinogen Persisting Perception Disorder Diagnosis
In October 2008 she was prescribed 0.5–1.0 mg risperidone without any effect. The various aspects of HPPD are largely self-reported by the patient that is presenting. In very rare cases, people have had HPPD without ever having taken a hallucinogenic drug. Also called “magic mushrooms,” these psychedelic drugs look just like ordinary mushrooms. Evidence not included in our systematic review suggested that low dosages of atypical antipsychotics may be useful, specifically Aripiprazole (5–10 mg/day) 23, also because of its efficacy in substance and alcohol use disorders 74. A latent period may antecede the onset of returning visual occurrences.
What Are the Symptoms of HPPD?
Some types of drugs that have delivered positive results include antipsychotics, some drugs used for treating PTSD, and naltrexone, which is used to treat opioid and alcohol dependency. Most people who experience HPPD only have symptoms for a short time after drug use. However, there are examples of people experiencing HPPD symptoms over a number of years. If a doctor is not sympathetic to a person’s symptoms or does not want to explore HPPD as a diagnosis, then it is a good idea to speak to a different doctor.
4. Mental Illnesses Comorbid with HPPD
People with Hallucinogen Persisting Perception Disorder re-experience the same hallucinations they had on a past psychedelic “trip.” Oftentimes, these hallucinations are visual but they can affect the other senses as well. For example, someone with HPPD may see colors more intensely or notice halos of different-colored light around objects. Objects might also appear either Substance abuse too big (macropsia) or too small (micropsia).
Memory functions, attention span, visuo construction and frontal-executive functions were examined. No significant cognitive deficits were detected, except for underperformance in the test for phasic attention. With respect to her mental wellbeing, the patient’s self assessment indicated a light to medium depressive and anxiety disorder, most likely attributable to the chronic distress resulting from the abnormal perceptions. It is important to note that in contrast to classical psychotic disorders, patients with HPPD recognize the unreal nature of their visual disturbances which qualifies them as pseudohallucinations. Although researchers don’t know why some people get HPPD and others don’t, they know HPPD happens because you’ve used hallucinogenic drugs in the past.
- With research that is currently available, it is strongly suggested that psychedelic drugs have great potential to enhance treatments for various mental health conditions.
- Visual aberrations can occur periodically in healthy individuals – e.g., afterimages after staring at a light, noticing floaters inside the eye, blue field entoptic phenomenon or seeing specks of light in a darkened room.
- Empirically, clinicians still lack a model identifying what specific factors or elements of set and setting will maximize the effectiveness of psychedelic-assisted therapies.
Who is eligible for psychedelic therapy?
Lamotrigine has shown to be efficacious in a recent severe case of HPPD with some EEG abnormalities (Anderson et al., 2018). These medications may also be helpful when visual disturbances are accompanied by co-occurring mood swings and mood disorders. Some people experience these visual disturbances only once after using hallucinogenic drugs. For others, the disturbances may occur frequently but not be very bothersome. Abraham suggested that all three can arise from a broader mechanism of disinhibition in sensory perception, affect and sense-of-self occasioned by psychedelic experience. It is not uncommon for depersonalization-derealization to be the most distressing symptom of the condition.
The neuroplasticity theory may explain why teenagers are more susceptible to HPPD, as their brains are more plastic than adults. This theory could also explain why sometimes HPPD can be resolved or decreased by having another psychedelic experience. Because HPPD is relatively under-reported and under-researched, we still don’t know a huge deal about HPPD. Here we present the case of 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. It can be harder to get symptoms to go away for type 2, and it may mean you need to treat it for the rest of your life.
Which drugs cause HPPD?
A 33-year-old female patient developed a hallucinogen-persisting perception disorder (HPPD) after lysergic acid diethylamide (LSD) hppd symptoms abuse for a year at the age of 18. Specifically, she reported after images, perception of movement in her peripheral visual fields, blurring of small patterns, halo effects, and macro- and micropsia. Previous treatment with antidepressants and risperidone failed to ameliorate these symptoms.

Clinical experience and an extensive and comprehensive knowledge of these phenomena are vital for successful treatment outcomes. Reaching an HPPD diagnosis may be easier if your doctor is familiar with the condition and your past drug use. Your doctor will want to know your personal health history, as well as a detailed account of what you’ve experienced. If you experience unexplained hallucinations, it’s important to see a doctor. The doctor may perform an examination, obtain laboratory tests, and take an image of your brain. Researchers and doctors do not yet have a solid understanding of who develops HPPD and why.

According to studies, the amount of a substance you took doesn’t seem to make a difference in your risk of getting HPPD. 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.
