Post-COVID Condition and Neuroinflammation: Possible Management with Antioxidants (2025)

Post-COVID condition (PCC) is a complex syndrome characterized by the persistence of diverse symptoms-including respiratory, neurological, and psychiatric manifestations-that last for weeks or months after acute Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. Epidemiological data indicate a higher prevalence among women and older adults, with significant impacts on daily functioning. The pathophysiology of PCC is multifactorial, involving immune dysregulation, viral persi

Peripheral Endocannabinoid Components and Lipid Plasma Levels in Patients with Resistant Migraine and Co-Morbid Personality and Psychological Disorders: A Cross-Sectional Study (2024)

Resistant migraine characterizes those patients who have failed at least three classes of migraine prophylaxis. These difficult-to-treat patients are likely to be characterized by a high prevalence of psychological disturbances. A dysfunction of the endocannabinoid system (ECS), including alteration in the levels of endocannabinoid congeners, may underlie several psychiatric disorders and the pathogenesis of migraines. Here we explored whether the peripheral gene expression of major components o

Medical cannabis use in Australia seven years after legalisation: findings from the online Cannabis as Medicine Survey 2022 (CAMS-22) (2024)

<title>Abstract</title> Background Cannabis was legalised for medical purposes in 2016. Uptake was initially slow, but since 2019 there has been a large increase in the number of Australians who have been prescribed cannabis for medical reasons. Yet a significant number of consumers continue to treat their medical conditions via illicitly-sourced cannabis. Little is known about how these two groups of medical cannabis consumers differ. Methods The anonymous Cannabis-As-Medicine Survey 2022 (CAMS

The Role of Fatty Acid Binding Proteins in Neuropsychiatric Diseases: A Narrative Review (2025)

Fatty acid binding proteins (FABPs) transport lipids in the brain and may be involved in the course of various neuropsychiatric syndromes, e.g., major depressive disorder (MDD), anxiety, schizophrenia, neurodegenerative disorders, autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and substance use disorders (SUDs). However, the nature of this link is not sufficiently elucidated. To that end, we performed a comprehensive literature search on the role of FABPs in neu

Maternal Cannabis Use During Pregnancy and Neuropsychiatric Adverse Outcomes During Childhood and Early Adult Life (2025)

Cannabis use during pregnancy is increasing; the study of adverse outcomes in cannabis-exposed pregnancies is therefore important. Previous articles in this series described increased risks of maternal adverse outcomes, fetal adverse outcomes, birth defects in newborns, and autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in childhood. This article examines neuropsychiatric adverse outcomes in offspring gestationally exposed to cannabis. Currently available rese

An ethogram analysis of cutaneous thermal pain sensitivity and oxycodone reward-related behaviors in rats (2023)

Abstract Inter-relationships between pain sensitivity, drug reward, and drug misuse are of considerable interest given that many analgesics exhibit misuse potential. Here we studied rats as they underwent a series of pain- and reward-related tests: cutaneous thermal reflex pain, induction and extinction of conditioned place preference to oxycodone (0.56 mg/kg), and finally the impact of neuropathic pain on reflex pain and reinstatement of conditioned place preference. Oxycodone induced a signifi

Therapy in the Age of Legalized Marijuana: A Qualitative Study of Counselors’ Experience in Responding to Patient Marijuana Use (2022)

A qualitative phenomenological study, the lived experiences of clinicians who treat clients using marijuana pre- and post-legalization in California are explored. This study was conducted to better understand the misconceptions associated with user attitudes and beliefs about marijuana use and provide clinicians, researchers, and physicians with information on the overall physical and emotional effects of marijuana use. Since legalization, investigating attitude and belief changes was essential

Investigating the Relationship Between Cannabis Expectancies and Anxiety, Depression, and Pain Responses After Acute Flower and Edible Cannabis Use (2024)

<b>Objective:</b> Cannabis has been touted for a host of pharmacological and therapeutic effects and users commonly report reduced symptoms of physical and mental health conditions, including anxiety, depression, and chronic pain. While there is existing empirical evidence supporting these effects of cannabis use, little is known about the extent to which these effects result from pharmacological versus expectancy factors. We evaluated the associations between participants' cannabis expectancies

Tourette syndrome research highlights from 2023 (2024)

In this, the tenth annual update for the F1000Research Tics collection, we summarize research reports from 2023 on Gilles de la Tourette syndrome and other tic disorders. The authors welcome article suggestions and thoughtful feedback from readers.

FMR1 Disorders: Basics of Biology and Therapeutics in Development (2024)

Fragile X Syndrome (FXS) presents with a constellation of phenotypes, including trouble regulating emotion and aggressive behaviors, disordered sleep, intellectual impairments, and atypical physical development. Genetic study of the X chromosome revealed that substantial repeat expansion of the 5' end of the gene fragile X messenger ribonucleoprotein 1 (<i>FMR1</i>) promoted DNA methylation and, consequently, silenced expression of <i>FMR1</i>. Further analysis proved that shorter repeat expansi

Integrative Interventions for Improving Outcomes in Depression: A Narrative Review (2024)

Antidepressants are among the most used medications in the US, with significant deleterious effects on people’s well-being. At any given time, depression impacts approximately 1 in 10 Americans, causing wide and broad societal costs. Interest is developing for non-pharmacological treatments and preventative measures. We summarize the literature on non-invasive dietary and lifestyle approaches for treating depression. This review aims to inform future research and treatment programs for depressio

Predictors of Pain Management Strategies in Adults with Low-Back Pain: A Secondary Analysis of Amazon Mechanical Turk Survey Data (2023)

<b><i>Objective:</i></b> To evaluate the associations between baseline demographics, health conditions, pain management strategies, and health-related quality-of-life (HRQoL) measures with pain management strategies at 3-month follow-up in respondents reporting current low-back pain (LBP). <b><i>Study design:</i></b> Cohort study of survey data collected from adults with LBP sampled from Amazon Mechanical Turk crowdsourcing panel. <b><i>Methods:</i></b> Demographics, health conditions, and the P

The Protective Effects of GPR55 Against Hippocampal Neuroinflammation and Neurogenic Damage in CSDS Mice (2021)

Abstract BackgroundDepression is one of the most prevalent mental illnesses in the world today, the onset of depression is usually accompanied by neuroinflammation and neurogenic damage. Recently, G protein coupled receptor 55 (GPR55) has been associated with mood regulation as a third kind of cannabinoid receptor, and the activation of GPR55 was demonstrated recently to have a neuroprotective effect on hippocampal neurogenesis against inflammatory insult. However, its role in regulating depress

Cannabidivarin for the treatment of HIV-associated neuropathic pain: a randomized, blinded, controlled clinical trial (2019)

Background: HIV remains a major burden to the health care system and neuropathic pain is the most common neurological complication of HIV-infection. Since current treatment strategies often lack satisfying pain relief, cannabinoids are discussed as a new option. We investigated Cannabidivarin as treatment for HIV-associated neuropathic pain. Methods: We conducted a randomized, double-blind, placebo-controlled cross-over study. Patients underwent two successive treatment phases (4 weeks each) and
