Hallucinogen Persisting Perception Disorder: Etiology, Clinical Features, and Therapeutic Perspectives

HPPD does not cause people to have full hallucinations or delusions.

What Are the Symptoms of HPPD?

For example, you may need to rest and use calming breathing techniques if Drug rehabilitation these episodes cause you significant anxiety. If your doctor suspects another possible cause, such as side effects of a medication, they may request blood tests or imaging tests. These tests can help them eliminate other possible causes of your symptoms. People living with post-traumatic stress disorder (PTSD) experience flashbacks of stressful, even painful situations. Researchers have recognized two forms of HPPD (type 1 and type 2).

What precautions should be taken for hallucinogen persisting perception disorder?

The physical symptoms of HPPD are a type of “flashback” similar to what you might experience with post-traumatic stress disorder (PTSD), except it’s visual and not always distressing. These are all symptoms of hallucinogen persisting perception disorder (HPPD), a treatable condition psychedelic substance use could trigger. No change was observed in her mental state, with a persistent low to medium depression indicative of a dysthymic disorder (Beck Depression Inventory IV, Self-report Symptom Inventory 90 Items – Revised).

Some people who have taken psychedelics, like LSD or psilocybin (“magic mushrooms”), might experience an “endless trip” long after the more intense or intoxicating effects of these substances have worn off. 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. From 2006 to 2008 the patient received fixed doses of sertraline (200 mg/day) for 13 months, citaloprame (20–30 mg/day) for 6 months and fluoxetine (20 mg/day) https://ecosoberhouse.com/ for 5 months.

• Trying mindfulness, yoga, or meditation may help to reduce stress and anxiety.
• Clinical experience and an extensive and comprehensive knowledge of these phenomena are vital for successful treatment outcomes.
• While there is no cure for Hallucinogen Persisting Perception Disorder, those individuals who suffer from it can find some relief from their symptoms by reducing stress and avoiding substance use.
• Addition of SSRI-type antidepressants to the drug regime did not yield any beneficial effects.

Clinical experience and an extensive and comprehensive knowledge of these phenomena are vital for successful treatment outcomes. A representative, but not exhaustive, list of reported visual disturbances. While there is no cure for Hallucinogen Persisting Perception Disorder, those individuals who suffer from it can find some relief from their symptoms by reducing stress and avoiding substance use. HPPD is also treated with several types of medication, through regimens that should be tailored to each individual.

It’s important to seek professional help if these symptoms persist or interfere with daily life. Although data is limited, research shows only 4% to 4.5% of people who take hallucinogenic drugs get it. 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. According to studies, the amount of a substance you took doesn’t seem to make a difference in your risk of getting HPPD.

How Common Is HPPD?

Thus, the serotonergic antidepressants administered during this period proved largely ineffective. However, the patient noticed a reduction in her anxiety and phobias that was also reflected in her psychological test scores. As for her personality, the patient’s self esteem deteriorated even further during the 18-month observation period whereas obsessive–compulsive and anti-social traits receded.

• While the drugs may provide these benefits, they can also cause side effects, including hallucinogen persisting perception disorder or HPPD.
• The contents of the perception and visual imagery range extensively 17,19.
• 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.
• These symptoms can last for weeks, months, and sometimes even years.
• The doctor may perform an examination, obtain laboratory tests, and take an image of your brain.
• However, in HPPD, they tend to be less intense — it is mostly vision that is affected, rather than the other senses.
• Often, these are negative events that feel intrusive, unwanted, and unpleasant.

Which drugs cause HPPD?

The effectiveness of Benzodiazepines may be related to their activity on the cortical serotonergic-inhibitory inter-neurons with GABAergic outputs 2,4. Alprazolam (0.25–0.75 mg/day) has been prescribed with some success and Clonazepam (0.5–1.5 mg/day) appears to be the most reliable and effective benzodiazepine even at low doses 17,18,51,67. Higher doses (4 mg/day) have also been used with good outcomes 68. Clonazepam may act on serotonergic systems, improving, enhancing, and augmenting transmission 17,18,51,67, thus promoting alleviation and a marked improvement 51,67.

Treatment course

• The total remission has been reported in a single patient with flashbacks and anxiety treated with 0.25 mg of Clonidine three times a day for two months 59.
• To date, no studies have investigated the potential use of rTMS in HPPD.
• In the International Classification of Diseases, 10th revision (ICD-10), such hallucinogen-induced echo psychoses are listed under F16.70 Dilling et al. 1991; Pechnik and Ungerleider, 2004.
• These include, but are certainly not limited to micropsia, macropsia, floaters, fractals, monochromatic vision, acquired dyslexia, visual snow, and other strange visual perceptions13.

These are generally considered to be the first line medications for treatment of HPPD. Researchers do not fully understand how these conditions relate to HPPD, but many report that they experience them alongside visual disturbances. Hallucinogen persisting perception disorder can lead to anxiety, depression, and impaired cognitive function but does not typically cause other physical health issues.

• Closely related to LSD in its psychotropic actions is psilocybin, which produces similar but shorter-lasting intoxications.
• During a year-long trial of lamotrigine, with a maximum dose of 200 mg, the patient experienced significant relief from her symptoms, some of which disappeared completely.

Many medical professionals often misdiagnose Hallucinogen Persisting Perception Disorder as one of the aforementioned disorders. Misunderstanding, misdiagnosis, skepticism and maltreatment of this condition is highly pervasive. 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.

Instead, episodes happen suddenly, without a sign that they’re coming. During an episode, you may feel like you’ve lost some or all control. HPPD type 2 can greatly affect your ability to function and take part in daily activities.
