58. Substance-Induced Psychotic Disorder
Substance- or medication-induced psychotic disorder is
characterized by hallucinations and/or delusions due to
the direct effects of a substance or withdrawal from a
substance in the absence of delirium
59. Substance-Induced Psychotic Disorder DSM5
A.
Prominent
hallucinations or
delusions.
B.
There is evidence
from the history,
physical
examination, or
laboratory findings
that either:
the symptoms in Criterion A
developed during, or within
a month of, substance
intoxication or withdrawal
C.
The disturbance is
not better
accounted for by a
psychotic disorder
that is not
substance induced
the symptoms precede the onset of the substance use
the symptoms persist for a substantial period of
time(e.g., about a month) after the cessation of
acute withdrawal or severe intoxication
there is other evidence that suggests the existence
of an independent nonsubstance-induced psychotic
disorder (e.g., a history of recurrent nonsubstance-
related episodes).
D.
The disturbance
does not occur
exclusively during
the course of
delirium
medication used is
etiologically related to
the disturbance

Does substance-induced
psychotic disorders progress to schizophrenia?
*Rajiv Tandon M.D., Sonia Motin Shariff, M.D. 2019
Swedish national
registry-based study*
7,606 individuals who had an index registry
diagnosis of substance induced psychotic disorder
assessed their diagnostic evolution over an
average of 7 years,
as well as how that related to their work history
diagnostic data on first-, second-, and third-
degree relatives of these individuals
examined how individual diagnostic outcomes
related to familial risk of alcohol or drug
abuse and nonaffective psychosis.

psychotic disorder is better explained
as a drug-precipitated disorder in highly vulnerable
individuals rather than a syndrome
predominantly caused by drug exposure.”
