These selective serotonin reuptake inhibitors (SSRIs) alleviated depression but did not relieve the HPPD symptoms. Due to weight gain the SSRIs were discontinued in September 2008. In October 2008 she was prescribed 0.5–1.0 mg risperidone without any effect. The hppd symptoms 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.

- Instead, episodes happen suddenly, without a sign that they’re coming.
- At variance with DSM-IV-R, ICD-10 recognizes hallucinogen-induced visual disturbances as lasting only seconds to minutes.
- The alterations in brain activity may be due to shifts in levels of the brain chemical gamma-aminobutyric acid or GABA.
What Are the Symptoms of HPPD?
As such, the doctor may ask a number of questions to reach a diagnosis. More research is needed to understand the changes in the brain that cause HPPD symptoms. These individuals do not relive any other aspects of the feeling of being on drugs. Though it can take time to find the right treatment regimen and begin to feel comfortable again, it is a process that is well worth the effort.
- As a result, it’s important to develop a plan of action to respond when they do.
- However, reports have highlighted that other psychoactive drugs which aren’t classically psychedelic, such as MDMA, ketamine, and cannabis, can onset HPPD.
- The hallucinations are typically long, and can come and go over the course of months or years.
- It’s unclear how many people experience this condition because people with a history of recreational drug use may not feel comfortable admitting this to their doctor.
- Researchers have recognized two forms of HPPD (type 1 and type 2).

The primary risk factor for HPPD disorder is using LSD and other hallucinogenic drugs. The complex phenomenology of acute hallucinogen-induced psychosis has been described and analysed extensively over the years. However, the clinical relevance of the long-term psychological sequelae which include so-called flashbacks remains unclear Hermle et al. 1992; Hermle et al. 2008. Moreover, a consistent etiological model drug addiction treatment to explain these effects has yet to be proposed.
Symptoms and Signs of HPPD
- One theory is that taking hallucinogens changes the way the brain processes visual information, causing it to see things incorrectly or superimpose colors, patterns and images over things that exist in the environment.
- Some types of therapy used to treat those conditions may be helpful in managing HPPD symptoms as well.
- 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.
- Likewise, bright lights in an otherwise dark environment may generate trails and halos.
Learning relaxation techniques like deep breathing or mindfulness exercises can help those with HPPD disorder remain more in control when flashbacks occur. Taking steps to manage stress through exercise, enjoying hobbies, socializing with others, listening to music and engaging in other activities may help reduce the frequency of flare-ups. A MEDLINE literature search (1994–2011) with the keywords ‘Hallucinogen persisting perception disorder HPPD’ was conducted.
Symptoms Reported by DSM V
In its pure state, it’s a white crystalline substance, but you only need a very small amount to feel the effects. People typically take the drug in sugar cubes or on small gelatin sheets that dissolve on the tongue. Hallucinogen-persisting perception disorder (HPPD) causes a person to keep reliving the visual element of an experience caused by hallucinogenic drugs. However, the ‘success’ of pharmacotherapy for HPPD should be treated with caution as this disorder appears to have a high propensity for spontaneous remissions – up to 50% of cases within a few months Abraham, 2001. In this context, the rarely ever documented occurrence of flashbacks in controlled studies of hallucinogen action should be mentioned. Apparently a favourable protective ‘setting’ may prevent the development of anxiety and psychotic decompensation as well as the loss of self control.
Little research explains what causes HPPD, but certain factors can increase your risk. Hallucinogen persisting perception disorder (HPPD) signs include the presence of recurring visual disturbances after using a hallucinogen, such as LSD (lysergic acid diethylamide) or PCP (phencyclidine). HPPD can affect mental health and cause ongoing stress and concern. 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.
