Abstract
It is a paradox that psychotomimetic drugs can relieve symptoms that increase risk of and cooccur with psychosis, such as attention and motivational deficits (e.g., amphetamines), pain (e.g., cannabis) and symptoms of depression (e.g., psychedelics, dissociatives). We introduce the ideas of psychotomimetic compensation and psychotomimetic sensitization to explain this paradox. Psychotomimetic compensation refers to a short-term stressor or drug-induced compensation against stress that is facilitated by engagement of neurotransmitter/modulator systems (endocannabinoid, serotonergic, glutamatergic and dopaminergic) that mediate the effects of common psychotomimetic drugs. Psychotomimetic sensitization occurs after repeated exposure to stress and/or drugs and is evidenced by the gradual intensification and increase of psychotic-like experiences over time. Theoretical and practical implications of this model are discussed.

Grover S, Kathiravan S. Acute and transient psychotic disorders: A review of Indian research. Indian J Psychiatry 2023; 65:895-913. [PMID: 37841545 PMCID: PMC10569331 DOI: 10.4103/indianjpsychiatry.indianjpsychiatry_254_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Revised: 06/26/2023] [Accepted: 08/09/2023] [Indexed: 10/17/2023] Open
Abstract
Background Acute and transient psychotic disorder (ATPD) was recognized as separate from other psychotic disorders and described in the International Classification of Diseases (ICD) tenth revision for the first time. A lot of research on ATPD has been conducted in India over the last six decades, but a review focusing exclusively on Indian research on ATPD is not available. Aim This paper aims to review the literature on ATPD emerging from India. Methodology A combination of search terms "Acute and Transient Psychosis," "acute psychosis," "non-affective psychosis," "non-affective psychotic disorder," "reactive psychosis," "first-episode psychosis," and "India" were searched on various search engines like PUBMED, Medknow, Hinari, and Google Scholar. We also did a hand search for additional relevant articles, including published abstracts of the Indian Journal of Psychiatry from 2007 to 2023. Relevant papers were selected. Results The prevalence of ATPD varies across different study settings, and it tends to have an abrupt to acute onset, and is primarily associated with stress. Few studies have assessed the subtypes of ATPD, and symptom profile has been inconsistently reported. There is a lack of trials on the effectiveness or efficacy of antipsychotics in ATPD patients. In a large proportion of patients initially diagnosed with ATPD, the diagnosis remains stable, with recurrence varying from 10% to 46.6% based on the duration of follow-up. Conclusion There is a need for more multicentric studies, studies with larger sample sizes, and consistency in data about risk factors. There is a need to evaluate symptom profile, course, outcome, and treatment outcomes in patients with ATPD using validated instruments to improve our understanding. Further, there is a need for comparative studies to evaluate the risk factors for ATPD.

Abstract
The ICD-11 International Classification of Diseases and Related Health Problems will move toward a narrower concept of "acute and transient psychotic disorders" (ATPD) characterized by the remnant "polymorphic psychotic disorder" (APPD) of the current ICD-10 category, also including schizophrenic and predominantly delusional subtypes. To assess the validity of APPD, relevant articles published between January 1993 and September 2017 were found through searches in PubMed and Web of Science. APPD is a rare mental disorder and affects significantly more women than men in early-middle adulthood. Its diagnostic reliability is relatively low, and its consistency reaches just 53.8% on average over 8.8 years, but is significantly greater than either of ATPD subtypes, which are more likely to progress to schizophrenia and related disorders. Although APPD has distinctive features and higher predictive power, its rarity and the fleeting and polymorphic nature of its symptoms could reduce its usefulness in clinical practice and discourage research.

Abstract
The potential role in neuropsychiatric disease risk arising from alterations and derangements of endogenous small-molecule metabolites remains understudied. Alterations of endogenous metabolite concentrations can arise in multiple ways. Marked derangements of single endogenous small-molecule metabolites are found in a large group of rare genetic human diseases termed "inborn errors of metabolism", many of which are associated with prominent neuropsychiatric symptomology. Whether such metabolites act neuroactively to directly lead to distinct neural dysfunction has been frequently hypothesized but rarely demonstrated unequivocally. Here we discuss this disease concept in the context of our recent findings demonstrating that neural dysfunction arising from accumulation of the schizophrenia-associated metabolite l-proline is due to its structural mimicry of the neurotransmitter GABA that leads to alterations in GABA-ergic short-term synaptic plasticity. For cases in which a similar direct action upon neurotransmitter binding sites is suspected, we lay out a systematic approach that can be extended to assessing the potential disruptive action of such candidate disease metabolites. To address the potentially important and broader role in neuropsychiatric disease, we also consider whether the more subtle yet more ubiquitous variations in endogenous metabolites arising from natural allelic variation may likewise contribute to disease risk but in a more complex and nuanced manner.

Abstract
BACKGROUND Short-lived psychotic disorders are currently classified under "acute and transient psychotic disorders" (ATPDs) in ICD-10, and "brief psychotic disorder" (BPD) in DSM-5. This study's aim is to review the literature and address the validity of ATPDs and BPD. METHOD Papers published between January 1993 and December 2016 were identified through searches in Web of Science. Reference lists in the located papers provided further sources. RESULTS A total of 295 articles were found and 100 were included in the review. There were only a few studies about the epidemiology, vulnerability factors, neurobiological correlates and treatment of these disorders, particularly little interest seems to exist in BPD. The available evidence suggests that short-lived psychotic disorders are rare conditions and more often affect women in early to middle adulthood. They also are neither associated with premorbid dysfunctions nor characteristic family predisposition, while there seems to be greater evidence of environmental factors particularly in developing countries and migrant populations. Follow-up studies report a favourable clinical and functional outcome, but case identification has proved difficult owing to high rates of transition mainly either to schizophrenia and related disorders or, to a lesser extent, affective disorders over the short- and longer-terms. CONCLUSIONS Although the lack of neurobiological findings and little predictive power argue against the validity of the above diagnostic categories, it is important that they are kept apart from longer-lasting psychotic disorders both for clinical practice and research. Close overlap between ATPDs and BPD could enhance the understanding of these conditions.

Abstract
The aim of this study was to look into the balance of pro-inflammatory (TNF-α, IL-6) and anti-inflammatory (TGF-β) cytokines and their association with stress, alterations in HPA axis activity and the disease severity in acute psychosis. Socio-demographic and clinical details were collected from 41 in-patients with a diagnosis of Acute and Transient Psychotic Disorder. Holmes and Rahe Stress Scale for stress in the preceding year, and Brief Psychiatric Rating Scale at baseline and follow up (4-12 weeks) for psychopathology were applied. IL-6, TNF-α (pro-inflammatory), TGF-β (anti-inflammatory) and Cortisol (morning and afternoon values) were measured at baseline and follow up. A total of 30 out of 41 cases recruited had follow up data available. The levels of IL-6 (p<0.001), TNF-α (p<0.001) and TGF-β (p<0.001) at baseline were all found to be significantly elevated compared to 42 age and gender matched healthy controls. There was a significant increase in the levels of TNF-α (p=0.020) and morning levels of cortisol (p=0.009) and a significant decrease in the levels of TGF-β (p=0.004) and afternoon levels of cortisol (p=0.043) from baseline to follow up. This study showed that there was an increased level of both pro and anti-inflammatory cytokines at baseline and a prolonged pro - inflammatory compared to anti - inflammatory response which warrants larger prospective studies and comparative studies to patients with schizophrenia and bipolar disorders.

Abstract
Psychotic disorders are frequent among travelers (10 to 20 % of medical evacuations). The travel is a concentrate of stressors. Psychotic disorders are not a contraindication to travel. Special precautions should be taken for patients with psychotic disorders wishing to travel. These precautions could apply to patients at risk of transition to a psychotic disorder.

Abstract
Climate change is an emerging challenge to the mental health of entire humanity. Several studies, in recent times, have brought to light the adverse public mental health outcomes of extreme weather events for the suffering communities. The general public and the policy making bodies need to gain awareness about these impacts. Through such awareness, communities and their governments can institutionalize mechanisms to provide psychological support to the populations affected by climate change, before it becomes a massive public health challenge and starts affecting the social and vocational lives of people. There is an urgent need for addressing these impacts. The aim of this paper is to provide an overview of the deleterious effects of climate change related extreme weather events on mental health, the worldwide response of several communities to such events, and preparedness of the public and government to deal with these adverse mental health impacts. Policy imperatives to prevent and mitigate these impacts have been suggested. It is hoped that the psychologists, governments, and communities will act earnestly to prevent the impending harm to human mental health due to climate change.

Abstract
Investigation of patients' subjective perspective regarding the effectiveness - as opposed to efficacy - of antipsychotic medication has been hampered by a relative shortage of self-report measures of global clinical outcome. This paper presents data supporting the feasibility, inter-item consistency, and construct validity of the Patient Assessment Questionnaire (PAQ)-a self-report measure of psychiatric symptoms, medication side effects and general wellbeing, ultimately intended to assess effectiveness of interventions for schizophrenia-spectrum patients. The original 53-item instrument was developed by a multidisciplinary team which utilized brainstorming sessions for item generation and content analysis, patient focus groups, and expert panel reviews. This instrument and additional validation measures were administered, via Audio Computer-Assisted Self-Interviewing (ACASI), to 300 stable, medicated outpatients diagnosed with schizophrenia or schizoaffective disorder. Item elimination was based on psychometric properties and Item-Response Theory information functions and characteristic curves. Exploratory factor analysis of the resulting 40-item scale yielded a five factor solution. The five subscales (General Distress, Side Effects, Psychotic Symptoms, Cognitive Symptoms, Sleep) showed robust convergent (β's=0.34-0.75, average β=0.49) and discriminant validity. The PAQ demonstrates feasibility, reliability, and construct validity as a self-report measure of multiple domains pertinent to effectiveness. Future research needs to establish the PAQ's sensitivity to change.

Abstract
A great deal of interest has been centered upon activated inflammatory processes in schizophrenia and their contribution to disease-relevant brain and behavioral impairment. In contrast, the role of anti-inflammatory signaling has attracted somewhat less attention in this context. The present article focuses on the emerging role of anti-inflammatory signaling in schizophrenia and discusses the potential influence of altered anti-inflammatory activity on progressive inflammatory processes, physical and metabolic functions, and treatment effects related to the use of conventional antipsychotic drugs and immunomodulatory agents in the pharmacotherapy of schizophrenia. By reviewing existing evidence, it appears that enhanced anti-inflammatory activity has many faces in schizophrenia: On the one hand, it may effectively limit potentially harmful inflammatory processes and may contribute to the improvement of psychopathological symptoms, especially when the anti-inflammatory system is boosted at early stages of the disease. On the other hand, enhanced anti-inflammatory activity may render affected individuals more susceptible to distinct physiological abnormalities such as cardiovascular disease, and may further impede the resistance to specific infectious agents. Therefore, an enhancement of anti-inflammatory signaling in schizophrenia might not simply be said to be either advantageous or disadvantageous, but rather should be interpreted and dealt with in a context-dependent manner. Increased awareness of the multiple roles of anti-inflammatory signaling may readily help to reduce additional health burdens in schizophrenia, and at the same time, may provide opportunities to further explore the benefits associated with anti-inflammatory strategies in the symptomatological and/or preventive treatment of this disorder.

Abstract
INTRODUCTION Behavioral emergencies constitute an important component of emergencies worldwide. Yet, research on behavioral emergencies in India has been scarce. This article discusses the burden, types, and epidemiology of behavioral emergencies in India. METHODS A computerized search of Medline, Psychinfo, and Cochrane from 1975 to 2009 was performed, and all articles were evaluated and collated. The results were summarized. RESULTS AND CONCLUSIONS There is an acute need for psychiatric emergency services in India. Suicides, acute psychoses, and substance-related problems form the major portion of behavioral emergencies, while current trends show a rise in disaster- and terrorism-related emergencies.

Abstract
Since the early 20th century, a group of nonaffective psychoses with acute onset and brief duration have been described in different countries under various names, including cycloid psychosis, bouffée délirante, and reactive psychosis. These psychoses share several characteristics, including benign course, greater prevalence in women than men and in developing countries than in industrialized countries, and high prevalence of premorbid psychological and physiologic stressors. However, the variations in names and minute details of symptomatology have overshadowed the basic similarities across these various descriptions. Confusion in classification persists in the two contemporary diagnostic systems, the DSM-IV and the ICD-10. We believe that most cases of these psychoses could be captured under a broad, unified category of nonaffective psychosis with acute onset and brief duration, and urge the authors of the upcoming revisions of the DSM and ICD to create such a category. A unified diagnostic category for these disorders would reduce unnecessary fragmentation in the diagnostic systems and assist in the progress of research on these rare conditions.

Abstract
Artemisinin, by the name of Qinghaosu, has been used in China for the treatment of fever over the years. Recently, a number of artemisinin derivatives such as artesunate, artemether, dihydroartemisinin, and arteether have been developed and have found widespread clinical use because of their efficacy against resistant forms of all plasmodial species and a favorable side-effect profile. However, concerns have been expressed about the neurotoxic effects of artemisinin derivatives based on some animal and human studies. We present a case of alpha/beta-arteether-induced mania in an adolescent having a family history of chloroquine-induced psychosis to discuss the hereditary predispositions, possible mechanisms, management, and clinical implications of this rare adverse event.

Abstract
OBJECTIVE The study aimed to establish clinical predictors of non-affective acute remitting psychosis (NARP) and assess whether these patients showed a distinct serotonergic profile. METHOD First-episode never treated psychotic patients diagnosed of paranoid schizophrenia (n=35; 21 men and 14 women) or NARP (n=28; 15 men and 13 women) were included. RESULTS NARP patients showed significantly lower negative symptomatology, better premorbid adjustment, shorter duration of untreated psychosis, more depressive symptomatology and a lower number of 5-HT2A receptors than the paranoid schizophrenia patients. In the logistic regression, the four variables associated with the presence of NARP were: low number of 5-HT2A receptors; good premorbid adjustment; low score in the item 'hallucinatory behaviour' and reduced duration of untreated psychosis. CONCLUSION Our findings support the view that NARP is a highly distinctive condition different from either affective psychosis or other non-affective psychosis such as schizophrenia, and highlight the need for its validation.

Abstract
Mental health problems are relevant for every country. They are particularly important for low-income countries which face a high burden of illness due to infectious disease, greater socio-economic disparities, and have limited resources for mental health care. There is a great mismatch in the areas of mental health research, practice, policy and services in comparison to developed countries. There have been a few studies that have investigated major mental health problems prevailing in these countries but missed out significant health problems. Studies have tended to be more donor driven and conducted in tertiary centres. The low priority accorded to mental health by the policy makers, scarcity of human resources, lack of culture-specific study instruments, lack of support from scientific journals have been some of the impediments to mental health research in these countries. In addition, lack of community participation and absence of sound mental health policies have deprived the vast majority of the benefit of modern psychiatric treatments. Recently, with increase in collaboration in research, availability of treatment including low-priced psychotropics, and a growing emphasis on the need for mental health policy in some low-income countries, the bleak scenario is expected to change.

Abstract
Fever (pyretotherapy) was used for psychosis during the turn of the 19th century, but pyretotherapy (ie, the treatment of a disorder by inducing fever) fell out of use after the introduction of convulsive methods. Here, we report on a case of schizoaffective disorder and review classical and recent literature on fever and psychosis. The patient developed auditory hallucinations, persecutory delusional ideas, and was terrified soon upon his arrival in a foreign country. After being treated for 12 days with olanzapine and haloperidol, he developed a fever due to urinary infection; his creatine phosphokinase levels were high, prompting the suspension of antipsychotics. Psychotic symptom resolution followed immediately fever abatement. Antipsychotics were reintroduced at lower dosages. He was discharged asymptomatic with a prescription of olanzapine 15 mg/day and haloperidol 3 mg/day. The time course of symptom resolution in this patient suggests that fever had a beneficial role in this case. The associations between body temperature changes and psychotic symptoms need to be further studied.

Abstract
OBJECTIVE To investigate the concept of 'Non-affective Acute Remitting Psychosis' (NARP) in a group of patients with first episode psychosis in Iran. METHOD This is a 24-month follow-up study of 54 patients with first-episode psychosis admitted consecutively to a psychiatric hospital in Tehran, Iran. At the end of follow-up, consensus judgments were made on fulfillment of the NARP criteria as well as illness course and treatment. NARP was defined as a psychotic illness with acute onset (developed within 1 week), short duration (remission within 6 months), and the absence of prominent mood symptoms. RESULTS Of 49 patients who completed the follow-up, 15 (30.6%) had NARP, accounting for 60% of non-affective psychoses. Ten patients with NARP remained relapse free, four had a very short-lived relapse, and only one developed a chronic illness. Throughout the follow-up, patients with NARP received fewer months of treatment than did patients with other non-affective psychoses. CONCLUSION The high proportion of NARP among patients with first episode psychosis, and the favorable course is in keeping with previous studies in developing countries.

Abstract
India is a country with a population of over 1 billion, and immense diversity in the languages spoken, levels of literacy, and social and cultural practices. Organising mental health services for this predominantly rural population is indeed a daunting task. Compounding this problem are low budgetary resources, the presence of competing and conflicting healing systems, scarcity of mental health personnel, ‘brain drain’, and the stigma of seeking help for problems related to the mind. This paper looks at the mental health scene in India with respect to services and research. It deals with conditions such as schizophrenia, acute psychoses, minor mental morbidity and drug misuse, highlighting aspects unique to the Indian scene. Indian families exhibit great tenacity in caring for relatives who are ill, and are a great resource in treatment and rehabilitation.

Abstract
Concept and nosologic status of acute and transient psychotic disorders, as they appear in the tenth edition of the International Classification of Disease, have seen review from the standpoint of validation and delineation from schizophrenia and affective disorders. Current research, particularly on the epidemiology, course, and outcome, and family genetic studies indicate that these disorders are common among women in developing countries, as well as among lower socioeconomic status and rural subjects. These patients have greater frequency of exposure to stress before childbirth, a family history of acute and transient psychotic disorder (and not of schizophrenia), and a course and outcome that is different from that of schizophrenia. The findings so far support the argument that acute and transient psychotic disorders are different from schizophrenia.

Abstract
This paper reviews the conceptual history of brief and acute psychoses. As psychotic disorders of usually dramatic symptomatology but nevertheless with a usually benign course, brief and acute psychoses have the air of a paradox. Thus, they have posed specific problems in regard to nosology, diagnostics and aetiology. Despite a strong convergence of the descriptive elements, the historical concepts of brief and acute psychoses have yielded different answers to the questions raised. Kahlbaum and Kraepelin set the stage on which brief and acute psychoses appeared "atypical". The concept of "bouffée délirante" used degeneration theory as a background for nosological and aetiological allocation. Similarly, the concepts of cycloid psychoses, reactive (psychogenic) psychoses, emotional psychoses and atypical psychoses have provided diverging but interrelated ways to delineate brief and acute psychoses, to determine their nosological status and to explain the coexistence of severe disorder and favourable prognosis. Modern classifications, namely the acute and transient psychotic disorder of ICD-10 and the brief psychotic disorder of DSM-IV, reflect the varied history of the concept.

Abstract
The comparative study of schizophrenia and related disorders across cultures has come a long way since Kraepelin advocated its cause, following his trip to Java at the beginning of the last century. The principal development since then has been the burgeoning of interest in the field, culminating in innovative and ambitious international collaborative research by the WHO. Despite reservations about covert ideology or about the more overt methodologic difficulties, the balance of evidence from these and similar studies suggests that: It is feasible to conduct such research despite the numerous hazards. There is a certain uniformity to the way schizophrenia presents globally; there are equally significant cultural differences. The outcome of schizophrenia appears to be better in developing, than developed cultures; reasons for this are far from clear, nevertheless, it can be safely assumed that culturally-determined processes, whether social or environmental, are partly responsible. Overall, the study of schizophrenia in different cultures has proved useful in establishing the pancultural and the culture-specific properties of this and related disorders.

Abstract
Modern classification systems have ignored the reactive psychoses, and little has been published using this concept during the last years. Nevertheless, the term is of interest in clinical practice where its presence is dependent on clinical skills and empathy. It is also important for a general understanding of the development of psychosis. The delineation from other acute psychoses needs clarification. Studies on reliability and validity are promising, but need extension. Traditionally, the concept of reactive psychosis has hardly been used outside Scandinavia, and it is encouraging that interest in brief psychoses seems growing in other cultures as well.

Abstract
BACKGROUND The short-term course of schizophrenia is reported to be better in some developing country settings. The long-term course in such settings, however, has rarely been studied. AIMS To examine the long-term course and mortality of schizophrenia in patients with a poor 2-year course. METHOD The report is based on two incidence cohorts of first-contact patients in urban and rural Chandigarh, India, originally recruited for the World Health Organization Determinants of Outcome of Severe Mental Disorders study. Patients were assessed using standardised instruments at 2- and 15-year follow-ups. RESULTS Ninety-two per cent of the patients with a poor 2-year course had a poor long-term course and 47% died - a nine times higher mortality rate than among patients with other 2-year course types. CONCLUSIONS In this developing country setting, a poor 2-year course was strongly predictive of poor prognosis and high mortality, raising questions about the adequacy of care for such patients.

Abstract
BACKGROUND The acute and transient psychotic disorders (ATPD) in ICD-10 advanced the nosology of remitting psychoses with acute onset. But the proposed criteria for ATPD--especially in regard to duration--are tentative and need to be validated. AIMS To evaluate: (a) the duration of remitting psychoses with acute onset; (b) the applicability of the ATPD criteria for these cases; and (c) differences in duration and ATPD diagnoses across sociocultural settings. METHOD Data from the World Health Organization Determinants of Outcome study were used. RESULTS The 98 cases of remitting psychoses with acute onset had a modal duration of 2-4 months, with 43% falling in this range. Mainly because of this, few met the ATPD criteria. Duration and diagnostic findings were similar across settings. CONCLUSIONS ATPD criteria need refinement, especially in regard to duration. Further studies aimed at early detection and assessment of onset and duration of these disorders are needed.
