Abstract
Objective: To identify the risk factors, frequency, symptoms, pathomechanism and treatment of IIP through a comprehensive literature review.
Methodology: Systematic literature review. The author first screened the titles and abstracts of all 288 records; out of which 102 studies that do not meet the eligibility criteria; full-text version of the remaining 186 articles (151 original articles and 35 review articles) were then screened by the principal investigator. After this screening, 14 original articles and 3 review articles were excluded, leaving 169 articles (137 original articles and 32 review articles).
Result: Psychotic symptoms are common amongst ice users, the frequency of any psychotic symptoms ranged from 16% to 81%, with a median of 78%. The prevalence of IIP ranged from 24% to 76%, the median of prevalence of IIP is 42%. The most frequently reported symptoms of IIP are delusions of persecution and auditory hallucinations.
Conclusion: Long-term studies that track the ice users for a decade or more are necessary to collect sufficient evidence to understand the relationship between Ice use and the development of IIP.
