Patients with schizophrenia and substance related comorbidity or substance induced psychotic disorder are difficult to treat. Although the prevalence of a comorbid substance use is approximately 40% in schizophrenia, such patients are usually excluded from clinical trials. We therefore performed a random-effects meta-analysis of all randomized controlled antipsychotic drug trials in this patient subgroup. Read More

Background: Substance induced psychotic disorders (SIPD) have been historically considered as associated with better clinical and functional outcomes than other psychotic diagnoses. As a result, treatments for those with SIPD are often considerably less intensive, yet this is not based on evidence. The present study aimed to examine whether differences exist between those with SIPD and other first episode psychosis (FEP) diagnoses in regards to demographic and clinical factors, and to determine the symptomatic, clinical and functional outcomes in those with SIPD.

Background: One major risk factor for the development of psychopathology is a family history of psychopathology (FHP). Cross-sectional studies have shown that FHP is associated with alterations in white matter microstructure in adolescents without current psychopathology; however, whether these associations persist throughout adolescence, particularly in those who remain resilient to developing psychopathology, is unclear.
Methods: Sixty-six adolescents underwent diffusion-weighted imaging at baseline (12-16 years of age) and at one or two follow-up visits (142 total scans). Read More

Background: The observation that N-methyl-D-aspartate glutamate receptor (NMDAR) antagonists such as ketamine transiently induce schizophrenia-like positive, negative and cognitive symptoms has led to a paradigm shift from dopaminergic to glutamatergic dysfunction in pharmacological models of schizophrenia. NMDAR hypofunction can explain many schizophrenia symptoms directly due to excitatory-to-inhibitory (E/I) imbalance, but also dopaminergic dysfunction itself. However, so far no new drug targeting the NMDAR has been successfully approved. Read More

Introduction: Isotretinoin, previously marketed as Accutane®, is an oral retinoid medication that is used to treat acne and other cutaneous disorders. Although the data is conflicting, previous reports suggest a causal relationship between isotretinoin and depression. When reviewing these previous reports, many patients who were diagnosed as "depressed" did not undergo a thorough psychiatric evaluation and/or were not diagnosed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM).

Purpose: To explore the unintended impact of a targeted case identification (TCI) campaign for first episode psychosis (FEP) on people not experiencing FEP ("non-cases") with respect to referral patterns and reasons for being a non-case.
Methods: Sources of referral, reasons for being a non-case, and subsequent referral destinations of non-cases were examined before and after a TCI.
Results: Following the TCI, a greater proportion of non-cases lived outside the study catchment area. Read More

Background And Aims: To review early case reports and experimental inductions of amphetamine and methamphetamine psychosis, prior to the prohibition of these drugs, to gain a better understanding of the nature and aetiology of methamphetamine psychosis.
Methods: Papers considered were historical case reports and case series of psychosis relating to the use and misuse of prescription amphetamine, focusing upon papers by Young & Scoville (1938), Connell (1958), and three subsequent experimental studies published in the early 1970s (Griffith 1972, Angrist & Gershon 1970 and Bell 1973), where psychosis was induced in volunteers using high-dose amphetamine and methamphetamine.
Results: High-dose methamphetamine and amphetamine can result in a paranoid psychosis which remits rapidly (within days) of discontinuing use. Read More

An association between marijuana use and schizophrenia has been noted for decades, and the recent emergence of high-efficacy synthetic cannabinoids (SCBs) as drugs of abuse has lead to a growing number of clinical reports of persistent psychotic effects in users of these substances. The mechanisms underlying SCB-elicited pro-psychotic effects is unknown, but given the ubiquitous neuromodulatory functions of the endocannabinoid system, it seems likely that agonist actions at cannabinoid type-1 receptors (CB1Rs) might modulate the functions of other neurotransmitter systems known to be involved in schizophrenia. The present review surveys what is currently known about the interactions of CB1Rs with dopamine, serotonin, and glutamate systems, because all three of those neurotransmitters are well-established in the pathophysiology of schizophrenia and psychosis.

Substance use disorders are becoming an increasingly significant problem in general hospitals and hence play a key role in consultation- and liaison psychiatry. Diverse psychotropic effects of various substances mimic psychiatric disorders. An alcohol intoxication can present depressive or manic symptoms, a cannabis delirium can present as a psychosis while stimulants use can suggest the diagnosis of an anxiety disorder. Read More

Cannabis (also known as marijuana) is the most frequently used illicit psychoactive substance in the world. Though it was long considered to be a "soft" drug, studies have proven the harmful psychiatric and addictive effects associated with its use. A number of elements are responsible for the increased complications of cannabis use, including the increase in the potency of cannabis and an evolution in the ratio between the two primary components, Δ-tetrahydrocannabinol (Δ-THC) and cannabidiol (toward a higher proportion of Δ-THC), Synthetic cannabinoid (SC) use has rapidly progressed over the last few years, primarily among frequent cannabis users, because SCs provide similar psychoactive effects to cannabis.
