What is another word for hallucinogen persisting perception disorder?
Pronunciation: [hɐlˈuːsɪnəd͡ʒən pəsˈɪstɪŋ pəsˈɛpʃən dɪsˈɔːdə] (IPA) 
Hallucinogen persisting perception disorder (HPPD) is a relatively rare condition that is characterized by the continued experience of sensory disturbances such as visual disturbances, after discontinuing hallucinogenic drug use. Although the prevalence of HPPD remains uncertain, it has been documented to occur in a relatively small proportion of individuals who engage in the use of hallucinogenic drugs, including LSD and psilocybin. Synonyms for HPPD may include hallucinogen persisting toxic disorder, persistent perception disorder, visual stress disorder, and flashbacks. While HPPD can be challenging to diagnose and treat, treatments such as cognitive-behavioral therapy and medication management may help alleviate symptoms and improve quality of life for individuals living with this condition.
