Hallucinogen-Persisting Perception Disorder HPPD
The patient had suffered from these rather distressing visual disturbances for more than two decades, which have had considerable impact on his daily living. He was given alcoholism different diagnoses which included Induced depersonalisation, depersonalisation-derealisation syndrome, LSD induced simple schizophrenia, depressive disorder and anxiety disorders. He had received treatment with antidepressants (Imipramine, Amitriptyline, and Venlafaxine); antipsychotics (Trifluperazine, Promazine); Benzodiazepines (Diazepam); Propranolol; and Fentazine.
What Is Hallucinogen-Persisting Perception Disorder (HPPD)?
HPPD as defined in DSM-IV-R is a post- hallucinogen intoxication disorder encompassing hppd meaning a range of mostly visual perceptual disturbances that occur within a certain time frame after cessation of drug use. The definition of this disease entity is entirely based on studies involving chronic LSD users Abraham, 1982, 1983. However, any additional psychopathological symptoms that may have occurred in this patient population were not given any consideration.
- She described these as attenuated ‘flashbacks’ – comparable with the experiences during acute LSD intoxication.
- It’s important to note that hallucinogen use does not always lead to HPPD.
- Pharmacotherapy of this very distressing condition is limited and any recommendations are based almost entirely on uncontrolled studies on small patient populations or even single case observations.
Hallucinogen-Induced Persisting Perception Disorder: A Case Report
Studies estimate that roughly 4% of people who have used psychedelics experience HPPD. One review of case studies and case series found that 76% of those with HPPD also experience micropsia or macropsia or “Alice in Wonderland” syndrome. You might still see visual oddities long after the effects of psychedelics wear off.
Causes and Risk Factors of Hallucinogenic Disorders
HPPD primarily affects visual perception, whereas substance-induced psychotic disorder can impact multiple senses. Certain lifestyle choices can increase the likelihood of developing HPPD. The primary risk factor is the use of hallucinogenic drugs, such as LSD, psilocybin, and MDMA. Higher doses and frequent use may amplify the risk, as can combining hallucinogens with other substances like alcohol or cannabis. Additionally, using hallucinogens in stressful or anxiety-provoking environments may heighten the risk of HPPD. Stressful experiences during a hallucinogenic trip can intensify its effects and contribute to lingering visual disturbances.
Pharmacogenomics and personalized medicine
Two patients fully recovered, two partially recovered, and four did not recover. 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. 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.

The most crucial step you can take to avoid HPPD is to stop misusing https://www.revenueknowmads.com/blog/substance-abuse-treatment/ hallucinogens. Some people may find they can manage flashbacks that are brief and not very intense. Those who experience flashbacks frequently and with higher intensity may need professional help, especially when the flashbacks are interfering with how they function in their daily routines.
