Schizophrenia and catatonia: from ICD-10 to ICD-11.

The classification of psychotic disorders has undergone a variety of changes. Since Karl Ludwig Kahlbaum's (Kahlbaum 1874) first descriptions of catatonic states and Emil Kraepelin's (Kraepelin 1883) nosological classification of psychotic syndromes in the second half of the nineteenth century, the diagnostic criteria for these disorders have been repeatedly modified, significantly impacting clinical practice. Eugen Bleuler (Bleuler 1911) coined the term "schizophrenia", emphasizing the disturbances in thinking, feeling and acting that he had observed.

Genetics of Response to ECT, TMS, Ketamine and Esketamine.

Treatment-resistant mood disorders are often managed with intensive interventions that include electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), ketamine, and esketamine, but the role of genetics in clinical response to those interventions is yet to be clearly determined. Here, we review the current literature on the genetics of response to these treatment modalities. To date, the limited number of studies done to investigate genetic predictors of treatment response have primarily focused on single variants in candidate genes, and none of these have been consistently reproducible.

Impairment of the GABAergic system in the anterior midcingulate cortex of heroin-addicted males.

Opioid addiction is a global concern and the largest health burden among drug use disorders. The multifunctional anterior midcingulate cortex (aMCC) is critical for processing nociceptive input and negative emotions, which play a prominent role in the maintenance of opioid addiction. GABAergic interneurons regulate the output of the aMCC, whose dysfunction has been linked to the behavioural abnormalities observed in addiction.

Differences in Blood Leukocyte Subpopulations in Schizophrenia: A Systematic Review and Meta-Analysis.

Importance: This study aims to provide robust evidence to support or challenge the immune hypothesis of schizophrenia.

Objective: To conduct a meta-analysis of reports on blood leukocyte subpopulations in schizophrenia vs healthy controls, examining disease- and treatment-related differences as well as potential confounders.

Data Sources: Systematic database search for English and non-English peer-reviewed articles in PubMed, Web of Science, Scopus, and Cochrane Library databases, with the last search in January 2024.
