HPPD is still poorly understood, but research points to neurobiological changes in visual processing pathways in the brain—likely involving serotonin receptors (especially 5-HT2A). Although HPPD is primarily visual, many people also report Alcohol Use Disorder ringing in the ears, muffled hearing, or increased sensitivity to sound (hyperacusis). Written informed consent was obtained from the individual(s) for the publication of any potentially identifiable images or data included in this article. The original contributions presented in the study are included in the article/supplementary material, further inquiries can be directed to the corresponding author/s. Having a flashback can be distressing, but calming or self-soothing activities like deep breathing, grounding techniques, and mindfulness can ease the psychological discomfort and help you to stay in the moment. It’s also important to learn your triggers so you can do your best to avoid them and better manage them when they do occur.
- The diagnosis of HPPD presents unique challenges for healthcare providers.
- Healthcare providers may conduct psychological evaluations and ask about physical symptoms.
- The risk of developing HPPD doesn’t correlate with frequency of use – some users experience symptoms after a single exposure, while others develop issues after multiple uses.

In addition to medication, mental health professionals frequently recommend talk therapy as a treatment for HPPD. Therapy can help people with the alcoholism disorder learn to manage stress and develop coping strategies for dealing with HPPD vision symptoms. These are all symptoms of hallucinogen persisting perception disorder (HPPD), a treatable condition psychedelic substance use could trigger.
How we reviewed this article:
There is little evidence that an individual’s chances of developing HPPD increase with their frequency of drug use; the disorder can also occur in people who have had little experience with hallucinogens. Unlike the immersive flashbacks that some people have after taking drugs, HPPD flashbacks are purely visual. This means that a person with HPPD just has visual disturbances, such as seeing blurry patterns, size distortion, and bright circles. They do not relive any other aspects of a drug trip, only the part that involved vision.
Understanding Hallucinogen Persisting Perception Disorder (HPPD)
Our partnership with the Visual Snow Initiative brings you a short introduction video on HPPD, visual snow, and how it can affect someone, helping you to understand the condition in a concise yet accurate way. In most cases, the symptoms of HPPD will gradually improve over time. Visual Snow Initative Founder Sierra Domb shares her story on how she first developed visual snow, what she has learned, and why she started her organization. Prescription‑style coverage for cannabis is still the exception, not the rule, but patients are pushing insurers to catch up. In this article, we examine what causes HPPD, its symptoms, how it is diagnosed, and ways to manage and prevent it. Knowing what it is and how to deal with it can help those who are struggling with this disorder.
Treatment and Recovery
Auditory experiences, like loud music at a concert, may be more intense than normal. It is important to note that HPPD hallucinations are always obvious as hallucinations to the individual experiencing them and don’t override their reality. Despite that, HPPD can still cause significant distress and interfere with one’s work and social life. 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. Also called “magic mushrooms,” these psychedelic drugs look just like ordinary mushrooms.
- It can cause ongoing problems with your vision, and come back again and again.
- Afterimages are lingering visual impressions that remain after the original image is gone.
- HPPD patients appear to be sensitive to first-generation antipsychotics at low doses, requiring monitoring of extrapyramidal side effects.
- If you are dealing with HPPD, you are not alone—this disorder is recognized in the DSM-V, yet it remains underdiagnosed, with fewer than 1% of psychologists familiar with its symptoms and treatment.
- However, there are examples of people experiencing HPPD symptoms over a number of years.
- Both anxiety disorders and HPPD can involve anxiety, restlessness, and difficulty concentrating.
Patients who receive coordinated care for both their HPPD and co-occurring conditions report better outcomes in symptom management and quality of life. Some people experience these visual disturbances only once after using hallucinogenic drugs. For others, the disturbances may occur frequently but not be very bothersome. 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. However, visual disturbances defined as HPPD also occur in people who have never used psychedelics or other drugs, especially those with anxiety disorders.
His paper “When the Trip Doesn’t End” talks extensively of his journey, research, and theories for effective treatments. Understanding how hallucinogens can affect your brain and mental health can help you make informed decisions. It’s important to be in a good mental state before using these substances, as pre-existing mental health issues can increase the risk of developing HPPD.
- Start your recovery journey with peace of mind, knowing your care is covered.
- Schizophrenia often develops gradually over time, whereas HPPD symptoms appear after drug use.
- Case 1 had a developmental change in the lingual gyrus, and case 8 had non-specific scattered T2-hyperintense lesions.
These symptoms may occur spontaneously or be triggered by stress, fatigue, or the use of substances such as alcohol or cannabis. In addition to visual disturbances, some individuals may also experience symptoms of anxiety or depression. Lamotrigine is a widely used antiepileptic and mood-stabilizing drug which acts by blocking sodium and voltage-gated calcium channels and inhibiting glutamate-mediated excitatory neurotransmission. Additionally, there are data supporting a neuroprotective effect Halonen et al. 2001. Given that excitotoxic destruction of inhibitory interneurons may play a role in at least some of the visual symptoms of HPPD (see below), lamotrigine was considered a possible treatment option for this patient.
Brain imaging or other diagnostic tests may be used to rule out other causes of psychosis in schizophrenia, though these are not typically necessary for diagnosing HPPD. The other most common symptoms experienced by patients were floaters, palinopsia, photophobia, photopsia and nyctalopia. Currently, the DSM-5 does not include visual snow, nyctalopia, photophobia or floaters in their description of HPPD. A revision of the diagnostic criteria to include these symptoms may better reflect the common presentations and guide clinicians in identifying patients presenting with a suggestive history.
