The HPPD Information Guide is here

For anything and everything HPPD in a concise, relatively accessible but still informed and scientific presentation, we advise readers check out our Information Guide, located in the namesake dedicated section on our site.

The Guide is intended to be a real-time document with edits over time - ideally with input from specialists and HPPD patients - to reflect new knowledge and increase accuracy. If you have any thoughts, comments, criticisms or questions, please contact us at info@perception.foundation
