Recent Advances in the Early Intervention in Schizophrenia: Future Direction from Preclinical Findings
AbstractPurpose of ReviewIn the past decade, there has been increasing interest in the potential benefit of early intervention in schizophrenia. Patients with schizophrenia show cognitive impairment for several years preceding the onset of psychosis. The author discusses the recent topics on prevention of schizophrenia.Recent FindingsPreclinical findings suggest that maternal immune activation (MIA) produces cognitive deficits as a prodromal symptom in juvenile offspring in rodents. Treatment with anti-inflammatory compounds, such as D-serine, 7,8-dihydroxyflavone (a TrkB agonist), sulforaphane (or its precursor glucoraphanin), and TPPU (1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea: a soluble epoxide hydrolase inhibitor), during adolescence might prevent the onset of behavioral abnormalities and parvalbumin immunoreactivity in the medial prefrontal cortex of adult offspring after MIA.SummaryBased on the role of inflammation and cognitive impairment in the prodromal state, early intervention using anti-inflammatory compounds (i.e., D-serine, sodium benzoate, TrkB agonist, Nrf2 agonist, soluble epoxide hydrolase inhibitor) may reduce the risk of subsequent transition to schizophrenia.

This article describes the epidemiologic features and clinical manifestations of psychosis in individuals with ASDs, while also discussing shared genetic risk factors and affected brain regions. Components of a diagnostic assessment, including a thorough developmental, behavioral, medical, and psychiatric history, will be reviewed. The authors highlight the manifestations of catatonia in this population and note the shared features between catatonia and ASDs. Finally, treatment approaches and areas for future study are suggested.
This study is a prospective, exploratory, qualitative analysis. Twenty midwives from Grenoble Alpes University Hospital who took care of one of the selected patients participated in this study. Two women had schizophrenia and one bipolar disorder. Interviews realized with a semi-structured guide were fully transcribed, anonymized and thematically analyzed. Topics have been structured according to the number of occurrences to build a thematic tree. RESULTS: Midwives felt insecure and resourceless when the postpartum care was unclear, insufficiently anticipated and in case of a danger for the women or the children. They ...
CONCLUSION: A psychotic experience could be traumatic for patients and lead to complete PTSD. Although it appears as a non-consensual clinical entity, from a likely epistemological slip of the definition of "psychotrauma", the consideration of potential PTSD-PP presents an undoubted clinical relevance. Indeed, it could help practioners to precise the semiological analysis of patients recovering from an acute psychotic episode; to impact the prognosis of psychosis, thinking about impairment on the quality of life and the affective and suicidal comorbidities; and to modify the therapeutic approach in the recovery o...
CONCLUSIONS: The diet of women diagnosed with schizophrenia did not deviate from the diet of healthy persons, although the nutritional mistakes that were made by them suggest to choose the nutritional therapy individually for each patient, after carrying out a detailed nutritional interview.

CONCLUSIONS: No supplementation of schizophrenia patients' diet is recommended; it is only justified in individual cases of patients in whom vitamin and mineral deficiencies were found on the basis of analysis of their food habits. However, it is necessary to provide each schizophrenia patient with appropriate food education that will allow them to choose products that contain all nutrients needed for proper functioning of the body, including the central nervous system.

Authors: Malewska-Kasprzak MK, Permoda-Osip A, Rybakowski J Abstract Purinergic system plays a role in the regulation of many psychological processes, including mood and activity. It consists of P1 receptors, with adenosine as the agonist, and P2 receptors, activated by nucleotides (e.g., adenosine 5'-triphosphate - ATP). Propounded disturbances of uric acid in affective disorders were related to the introduction of lithium for the treatment of these disorders in the 19th and 20th century. At the beginning of the 21st century, new evidence was accumulated concerning a role of uric acid in the pathogenesis and treat...
CONCLUSIONS: A statistically significant level of consistency of the whole scale and its individual domains with the results of the clinical assessment with the BNSS, speaks for the adequacy of the self - assessment of negative symptoms by a patient with schizophrenia. Good psychometric properties of the Polish version of the SNS obtained in the study can indicate its usefulness in the research on negative symptoms conducted in Poland.
