Summary
Research on substance-induced psychotic disorder (SIPD) criteria is limited, with a lack of evidence on validity across substances. New classifications are needed to reflect current data on substance-associated psychosis.
Area of Science:
- Psychiatry
- Clinical Psychology
- Neuroscience
Background:
- Substance-induced psychotic disorder (SIPD) is a recognized diagnosis in the DSM-IV-TR.
- Current diagnostic criteria for SIPD have been questioned due to limited empirical validation.
Purpose of the Study:
- To critically evaluate the existing DSM-IV-TR criteria for substance-induced psychotic disorder (SIPD).
- To identify gaps in research regarding the validity and application of SIPD diagnostic criteria.
Main Methods:
- A comprehensive literature search of electronic databases (e.g., MEDLINE, PubMed) from 1992-2007.
- Inclusion of studies using clinical or structured diagnostic interviews for SIPD diagnosis.
- Review of bibliographies from relevant articles and books.
Main Results:
- Forty-nine articles presenting clinical data on SIPD were identified.
- A significant portion of the literature consisted of case reports.
- A notable lack of research rigorously examining the validity of DSM-IV criteria across various substances was found.
Conclusions:
- There is a significant lack of information regarding the outcomes, treatment, and best practices for substance-associated psychotic episodes.
- Further research is essential to refine diagnostic criteria for SIPD.
- An alternative, broader classification inferring association rather than causation is proposed to better align with existing evidence.

01:24Substance Use Disorders Affecting Sleep
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...

01:28Psychosis and Antipsychotic Drugs: Overview
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic symptoms in all...
01:26Positive Symptoms Schizophrenia: Hallucinations and Delusions
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
01:26Psychosis: Goals of Pharmacotherapy
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...
