Purpose: A quarter of ICU-patients develop post-traumatic stress disorder (PTSD) after discharge. These patients could benefit from early detection of PTSD. Therefore, we explored the accuracy of text mining with self-narratives to identify intensive care unit (ICU) patients and surviving relatives at risk of PTSD in a pilot study.

Alternating bilateral sensory stimulation (ABS) is a clinical physical therapy technique effective in treating post-traumatic stress disorder (PTSD). However, its utilization in treating conditions beyond PTSD remains limited. Here, we present a protocol to reduce ethanol-induced conditioned place preference (CPP) using 4 Hz ABS.

Backgrounds: Memory and emotion are especially vulnerable to psychiatric disorders such as post-traumatic stress disorder (PTSD), which is linked to disruptions in serotonin (5-HT) metabolism. Over 90% of the 5-HT precursor tryptophan (Trp) is metabolized via the Trp-kynurenine (KYN) metabolic pathway, which generates a variety of bioactive molecules. Dysregulation of KYN metabolism, particularly low levels of kynurenic acid (KYNA), appears to be linked to neuropsychiatric disorders.

Psychedelics, historically celebrated for their cultural and spiritual significance, have emerged as potential breakthrough therapeutic agents due to their profound effects on consciousness, emotional processing, mood, and neural plasticity. This review explores the mechanisms underlying psychedelics' effects, focusing on their ability to modulate brain connectivity and neural circuit activity, including the default mode network (DMN), cortico-striatal thalamo-cortical (CSTC) loops, and the relaxed beliefs under psychedelics (REBUS) model. Advanced neuroimaging techniques reveal psychedelics' capacity to enhance functional connectivity between sensory cerebral areas while reducing the connections between associative brain areas, decreasing the rigidity and rendering the brain more plastic and susceptible to external changings, offering insights into their therapeutic outcome.
