Ja, maar misschien vervormt de stof de vervormingen?Madcat schreef:met sommige vormen van HPPD zie je dingen al redelijk vervormd, en dan is dat de normale situatie, en zullen sommige tripmiddellen niet echt spectaculair zijn. mss versterkt het wel, maar dat weet ik niet.

Hallucinogen Persisting Perception Disorder (Flashbacks)
The essential feature of Hallucinogen Persisting Perception Disorder (Flashbacks) is the transient recurrence of disturbances in perception that are reminiscent of those experienced during one or more earlier Hallucinogen Intoxications. The person must have had no recent Hallucinogen Intoxication and must show no current drug toxicity (Criterion A). This reexperiencing of perceptual symptoms causes clinically significant distress or impairment in social, occupational, or other important areas of functioning (Criterion B). The symptoms are not due to a general medical condition (e.g., anatomical lesions and infections of the brain or visual epilepsies) and are not better accounted for by another mental disorder (e.g., delirium, dementia, or Schizophrenia) or by hypnopompic hallucinations (Criterion C).
The perceptual disturbances may include geometric forms, peripheral-field images, flashes of color, intensified colors, trailing images (images left suspended in the path of a moving object as seen in stroboscopic photography), perceptions of entire objects, afterimages (a same-colored or complementary-colored "shadow" of an object remaining after removal of the object), halos around objects, macropsia, and micropsia.
The abnormal perceptions that are associated with Hallucinogen Persisting Perception Disorder occur episodically and may be self-induced (e.g., by thinking about them) or triggered by entry into a dark environment, various drugs, anxiety or fatigue, or other stressors. The episodes usually abate after several months but can last longer. Reality testing remains intact (i.e., the person recognizes that the perception is a drug effect and does not represent external reality). In contrast, if the person has a delusional interpretation concerning the etiology of the perceptual disturbance, the appropriate diagnosis would be Psychotic Disorder Not Otherwise Specified.
Diagnostic criteria for 292.89 Hallucinogen Persisting Perception Disorder (Flashbacks)
A. The reexperiencing, following cessation of use of a hallucinogen. of one or more of the perceptual symptoms that were experienced while intoxicated with the hallucinogen (e.g., geometric hallucinations, false perceptions of movement in the peripheral visual fields, flashes of color, intensified colors. trails of images of moving objects, positive afterimages. halos around objects. macropsia. and micropsia).
B. The symptoms in Criterion A cause clinically Significant distress or impairment in social. occupational. or other important areas of functioning.
C. The symptoms are not due to a general medical condition (e.g.• anatomical lesions and infections of the brain, visual epilepsies) and are not better accounted for by another mental disorder (e.g., delirium, dementia, Schizophrenia) or hypnopompic hallucinations.

Of dit komt door HPPD weet ik niet, ik hoor graag reacties van mensen met en zonder
