Recent evidence indicates that the occurrence of psychiatric disorders in patients is linked to a local "sterile" inflammation of brain or due to a systemic inflammation process that affects the central nervous system. This is supported by the observation that in peripheral blood of psychotic patients are detectable several mediators and markers of inflammation as well as clinical data on correlations between systemic chronic inflammatory processes and psychiatric disorders. This may explain why some reported anti-inflammatory treatment strategies have beneficial effects on ameliorating psychotic events. In this review we will present a concept that aberrant purinergic signaling and increases in extracellular level of adenosine triphosphate (ATP) in the brain parenchyma may lead to activation of Nlrp3 inflammasome in microglia cells and as a consequence microglia released danger associated molecular pattern (DAMP) proteins activate complement cascade (ComC) in mannan binding lectin (MBL) - dependent manner. Activation of ATP-Nlrp3 inflammasome-ComC axis may also orchestrate trafficking of stem cells released from bone marrow into peripheral blood observed in psychotic patients. Based on this, the ATP-Nlrp3 inflammasome-ComC axis may become a target for new therapeutic approaches, which justifies the development and clinical application of efficient anti-inflammatory treatment strategies targeting this axis in psychiatry.

Deep brain stimulation - A primer for psychiatrists.
Asian J Psychiatr
December 2024
OCD Clinic, Department of Psychiatry, National Institute of Mental Health and Neurosciences (NIMHANS), India.
Deep Brain Stimulation is a form of neurostimulation where electrical stimulation is delivered via intracranial electrodes over specific subcortical targets. It has been increasingly used as an alternative to ablative procedures for psychiatric disorders refractory to standard treatments. This review describes the common psychiatric indications for DBS, the current evidence base, putative mechanisms, and future directions.

Previous cross-sectional studies have utilized scales to explore potential indications of the moderating effect of resilience on the relationship between stressful life events (SLEs) and mental health. However, there remains a notable dearth of psychometrically driven models in longitudinal resilience research, especially concerning the prognosis of individuals with affective disorders and/or anxiety. This study aimed to investigate whether baseline resilience capacity, measured by the Connor-Davidson Resilience Scale, could mitigate the impact of SLEs on depressive symptoms assessed using the Beck Depression Inventory-II among 66 outpatients with depression and/or anxiety disorders during a follow-up period ranging from 4-8 years.

This study examined the relationship between change in symptom severity and personal recovery in patients with severe mental illness (SMI). Forty-nine outpatients at Mentrum/Arkin, Amsterdam, the Netherlands, were assessed at baseline and 3 years later, using the Brief Psychiatric Rating Scale and the Mental Health Recovery Measure. Correlation coefficients and linear regression analyses were used.

Exposure to sound energy may be a risk factor or a therapeutic intervention for Alzheimer's disease (AD). On one hand, noise has a harmful effect on people with AD by contributing to hearing loss, sleep disturbance, oxidative stress, inflammation, and excitotoxicity. But on the other hand, clinical trials and nursing home interventions with soundscape augmentation involving natural sounds have shown promising results in alleviating psychophysiological symptoms in people with AD.

Background And Objective: It is unclear whether variation in covert cerebrovascular disease prevalence is attributable to ethnic differences or to other factors. We aimed to examine the associations of country of residence with covert vascular brain injury (VBI) and cognitive dysfunction among Chinese adults residing in Canada and China.
Methods: This was a multisite cross-sectional study of Chinese adults aged 40-80 years in the Canadian Alliance for Healthy Hearts and Healthy Minds (CAHHM; January 1, 2014, to December 31, 2018) and Prospective Urban Rural Epidemiological-Mind (PURE-MIND; November 1, 2010, to July 31, 2015) cohorts living in Canada and China.
