Hallucinogen-persisting perception disorder

Hallucinogen persisting perception disorder (HPPD) is a rare but potentially long-term set of visual disturbances occurring following the use of psychedelic and or hallucinogenic drugs and causing impairment and distress. Treatment includes medication, talk therapy, and reducing anxiety and stress, which can exacerbate symptoms and may be implicated in the origin of HPPD in some users of psychedelic drugs. HPPD Type 1 is a mild form of hallucinogen persisting perception disorder. Those with this diagnosis tend to have benign visual flashbacks, with little disruption to daily life. Many of the flashbacks patients experience are similar to or the same as what they experienced while on psychedelic drugs.

What is Hallucinogen Persisting Perception Disorder (HPPD)?

— who requested anonymity to discuss his drug use and medical history — was on no other mind-altering substances beyond the caffeine in his mug. The fantastical visions, which he’s come to expect and in some ways https://ecosoberhouse.com/article/hallucinogen-persisting-perception-disorder-hppd-symptoms/ even enjoy, were a lingering effect of past drug use. 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. But there is a diagnosis called hallucinogen persisting perception disorder. It is described as the presentation of visual effects—like the effects of LSD—but long after the drug has left the body.

How we reviewed this article:

Some people experience these visual disturbances only once after using hallucinogenic drugs. For others, the disturbances may occur frequently but not be very bothersome. Some people using hallucinogenic drugs can re-experience the effects of the drug days, weeks, or even years after they used it. This is called hallucinogen persisting perception disorder (HPPD). HPPD can occur after the use of recreational hallucinogenic drugs.

• The female patient, now 33 years old and an architect by profession, reported the recreational use of up to 30 doses of lysergic acid diethylamide (LSD; ‘tabs’) during a 1-year stay in the USA at the age of 18.
• Experiencing symptoms of Type I or Type II HPPD after using psychedelics can make some people feel distressed or confused.
• Despite that, HPPD can still cause significant distress and interfere with one’s work and social life.
• Therapy, especially cognitive behavioural therapy (CBT), can help patients reduce the anxiety that can make HPPD symptoms worse, redirect their attention, and improve their mood.
• Researchers have recognized two forms of HPPD (type 1 and type 2).

Hallucinogen persisting perception disorder

• Some people experience these visual disturbances only once after using hallucinogenic drugs.
• Visual perceptions usually comprise perceived increased color intensity, dimensionality, vibrancy, illusory changes, and movements of a perceived object.
• Regardless of this research, it’s still important to be aware that these drugs are illegal in the U.S. and can still have detrimental effects.
• Additionally, only a small spectrum of hallucinogens seem capable of eliciting flashbacks, with LSD being the leading causative agent.
• 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.

Some experts believe a bad drug trip can inflict severe trauma that leaves people with a condition akin to PTSD. Dr. Wesley Ryan, who has treated about a dozen people with HPPD at his psychiatric practice in Marina del Rey, said such patients often experience depersonalization and derealization. They feel like they are witnessing their own life from the outside or that nothing is real. It’s possible that several different medical phenomena are lumped together under the HPPD umbrella.

It’s worth noting that it is possible for someone to show signs of HPPD and not have a history of taking hallucinogens. Researchers suggest that HPPD may be caused by alterations in the visual processing center of the brain triggered by an LSD trip. Yet another hypothesis suggests that people who are prone to anxiety during psychedelic trips may be more at risk of developing symptoms of HPPD later.

Symptoms Reported by DSM V

A therapist or psychologist can help you learn how to respond to stressors when they occur. Read on to learn more about HPPD, the symptoms you might experience if you have it, and how you can find relief. Because so few cases of HPPD are officially diagnosed, research is quite limited. That makes what doctors and researchers do know about the condition limited as well.

With the Cochrane Society’s strict criteria for evidence-based medicine as a yardstick, our current knowledge does not allow for any empirical recommendations as to the rational pharmacotherapy of HPPD. Future clinical research needs to be directed towards Halfway house randomized controlled trials to establish sound treatment guidelines, in particular for chronic forms of HPPD Halpern and Pope, 2003. As part of the initial psychiatric assessment, extensive neuropsychological profiling was undertaken (Table 1).

These are particularly helpful in treatment of HPPD II with co-morbid anxiety disorders11. Non-pharmacological management could include brain stimulation treatment, but this has not been fully substantiated or investigated. 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) for 5 months. These selective serotonin reuptake inhibitors (SSRIs) alleviated depression but did not relieve the HPPD symptoms. In October 2008 she was prescribed 0.5–1.0 mg risperidone without any effect.

There is usually a latent, asymptomatic period following the initial intoxication, before the onset of returning visual disturbances and other hallucinations. This latent period could range anywhere from minutes to years1118. Following informed consent, a trial of the antiepileptic lamotrigine was initiated to combat the unrelenting visual disturbances of the patient. The ‘sense of levitation’ indicates that this case of HPPD was more complex as it included more than just visual abnormalities.

Is what I’m feeling nirvana or burn out from LSD use?

• A person with HPPD has recurring sensory disturbances similar to the ones from past trips.
• Since then, Locke has developed a general working theory of what causes HPPD and how it works.
• You might still see visual oddities long after the effects of psychedelics wear off.
• Other, non-visual symptoms can include recurrent synesthesias, dissociation, auras, depersonalization, and derealization3.

After Dr. Henry Abraham, considered the grandfather of HPPD research, retired in 2017, Locke took on many of his patients. Since then, Locke has developed a general working theory of what causes HPPD and how it works. At its most severe, HPPD can destroy people’s lives or impair their basic faculties.
