They can affect a person's quality of life.In a study published by the American Academy of Neurology, a team of researchers set about validating the symptoms and case studies of patients with visual snow.

This.These variants probably represent an overlap in hallucinatory and illusory palinopsia but are included in illusory palinopsia since they often co-exist with the other illusory symptoms.

The 97 individual case reports described 64 unique manifestations of HPPD, which are detailed in Table 2where they are arranged in the six overarching categories we created.

 

Almost a decade on, more substantial evidence for the long-term effects of hallucinogens became available when Cohen and Ditman published the results of a survey among 62 scientific experts on mescaline and LSD, 44 of whom provided data on 5, people using these substances.

To facilitate a proper understanding of the outcomes of such surveys, we need to formulate and use a rigorous and well-operationalized classification of the perceptual phenomena of HPPD.

 

To answer that question, longitudinal studies are necessary.

Finally, an association between the first intake of the hallucinogenic drug and the onset of the HPPD symptoms must be established [19] [20].

 

In the light of our findings, we would like to see future research attempt to solve various theoretical and practical issues.
