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. 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. Thus far, SSRIs, benzodiazepines, risperidone, olanzapine and naltrexone have all been tried with sometimes contradictory outcomes (Table 2). Abraham suggested that all three can arise from a broader mechanism of disinhibition in sensory perception, affect https://ecosoberhouse.com/ and sense-of-self occasioned by psychedelic experience.
6. Second Line Medications
- Spam includes any topics outside of HPPD, or posts with unknown intentions.
- The type of investigations performed varied, and two patients had no neuroimaging or ophthalmic testing performed.
- These symptoms persisted for the last 13 years, with little change in intensity and frequency.
- They believe hallucinogens may inhibit systems in the brain that constantly filter signals that affect our perception.
Objects might also appear either too big (macropsia) or too small (micropsia). Auditory experiences, like loud music at a concert, may be more intense than normal. Regarding treatment options, a combination of medications may be needed according to the preceding or subsequent psychopathology.

Furthermore, after images, halos, and ‘glow worm’ effects occurred less frequently. Rapid improvement was registered even during the dosing-in phase of lamotrigine – before the administration of therapeutic doses. Addition of SSRI-type antidepressants to the drug regime did not yield any beneficial effects. Instead they increased the frequency of derealization and depersonalization episodes in the patient. This was reversed to a large extent upon cessation of SSRI therapy. The patient also noted positive effects of psychotherapeutic intervention on attention focusing and mood stabilization.
Hallucinogen Persisting Perception Disorder Diagnosis
Prior substance users can voluntarily elicit or produce visual disturbances with or without known triggers 4,17,18. After HPPD II onset, hallucinogenic events tend to occur more frequently, and their duration and intensity increase. There are many theories that hypothesize hppd symptoms the causal relationship between LSD and HPPD, but none of them have been validated. However, the long half-life and illicit nature of LSD use in uncontrolled environments may contribute to the frequency of flashbacks observed with this particular drug.
He had received treatment with antidepressants (Imipramine, Amitriptyline, and Venlafaxine); antipsychotics (Trifluperazine, Promazine); Benzodiazepines (Diazepam); Propranolol; and Fentazine. He was also prescribed Hydergine Drug rehabilitation (which helped reduce symptoms briefly) at one point. Second, methodological strategies (sample size, study design, diagnostic criteria, etc.) may vary greatly in several studies retrieved. Most studies included here investigated HPPD cases following the intake of LSD, even though other isolated cases described incidents following the intake of other serotonergic hallucinogens, and cannabis. Furthermore, most studies here retrieved do not specifically distinguish between the two types of HPPD, as previously discussed, by limiting the complete understanding of the clinical symptomatology and manifestation. Several case reports of reoccurring or prolonged persistent visual perceptual disturbances (HPPD) have been described occurring within a certain time frame after cessation of some hallucinogenic drugs (2, 53, 54).
