Prebiotics, Probiotics, Synbiotics for ADHD May Improve Symptoms in Children (2024 Review)

by

Probiotics and prebiotics show potential benefits in improving symptoms and quality of life in children with ADHD, but more extensive studies are needed to confirm these effects. Highlights: Positive Impact on Functioning: Lactobacillus rhamnosus GG (LGG) supplementation improved emotional, physical, social, and school functioning in children with ADHD. Reduction in Inflammation: Synbiotic 2000 reduced markers …

Guanfacine Reverses Cognitive Impairment in Long COVID (2024 Case Report)

by

Guanfacine extended release (GXR) may effectively improve cognitive impairments and brain activity in long-COVID patients. Highlights: Patient Presentation: A 32-year-old woman experienced cognitive impairments such as difficulty in word recall, reading, and writing, and delayed task completion following COVID-19 infection. Baseline Assessment: Initial tests showed poor performance in attention, working memory, and executive function, with …

High Zinc Levels Linked to Increased Risk of Parkinson’s Disease (2024 Study)

by

Zinc levels were found to have a causal effect on the risk of Parkinson’s disease, while other oxidative stress biomarkers showed no significant association. Highlights: A study identified a significant causal relationship between higher zinc levels and increased risk of Parkinson’s disease (PD). No causal effects were found between PD and other oxidative stress biomarkers …

ACOT7 Biomarker May Help in Early Diagnosis of Alzheimers Disease (2024 Study)

by

ACOT7 shows promise as a non-invasive serum biomarker for Alzheimer’s disease (AD) with high diagnostic accuracy. Highlights: Increased Expression: ACOT7 levels were significantly elevated in AD patients and animal models compared to controls. Correlation with Cognitive Decline: A strong negative correlation was observed between serum ACOT7 levels and MMSE scores (r = -0.85; p < …

Antidepressant Efficacy vs. CYP2C19 & CYP2D6 Metabolism Genetics (2024 Review)

by

CYP2C19 poor metabolizers showed a nominally higher antidepressant remission rate compared to normal metabolizers, but overall genetic variations in CYP2C19 and CYP2D6 were not significantly associated with antidepressant response. Highlights: Higher Remission Rate: CYP2C19 poor metabolizers had a nominally higher remission rate (OR = 1.46) compared to normal metabolizers, but this did not hold after …

High Methylmalonic Acid (MMA) Levels Linked to Depression & Mortality Risk (2024 Study)

by

Elevated methylmalonic acid (MMA) levels are associated with depressive symptoms and increased mortality risk, but depressive symptoms do not mediate the relationship between MMA and mortality. Highlights: Each standard deviation increase in MMA is associated with a small but significant increase in depressive symptoms. The association between MMA and depressive symptoms is more pronounced in …

Transcranial Direct Current Stimulation (tDCS) of Left Dorsolateral Prefrontal Cortex Seems Effective for Depression & Anxiety (2024 Review)

by

Transcranial direct current stimulation (tDCS) targeting the left dorsolateral prefrontal cortex (DLPFC) at 2-mA intensity effectively alleviates depressive symptoms and shows promise in reducing anxiety symptoms across various clinical conditions. Highlights: tDCS targeting the left DLPFC significantly reduces depressive symptoms, highlighting it as a transdiagnostic neural mechanism across diverse clinical conditions. The meta-analysis showed that …

LIT-001 (Oxytocin Receptor Agonist) Alters Pair Bonding in Prairie Voles (2024 Study)

by

A small-molecule oxytocin receptor-specific agonist, LIT-001, differentially affects the acquisition and expression of partner preference in prairie voles, enhancing bonding when administered before cohabitation but inhibiting it when given afterward. Highlights: LIT-001 Enhances Bonding Pre-Cohabitation: Administration of LIT-001 (10 mg/kg) before a 4-hour cohabitation period facilitated the acquisition of partner preference in male prairie voles. …

Blood Urea Nitrogen (BUN) & Creatinine Ratio vs. Cognition & Depression (2024 Study)

by

Elevated blood urea nitrogen and creatinine ratio (BUNCr) is associated with decreased cognitive function and increased depressive symptoms, with depressive symptoms mediating part of the relationship between BUNCr and cognitive decline. Highlights: BUNCr has a negative association with cognitive function, with higher BUNCr levels linked to lower cognitive performance. BUNCr is positively associated with depressive …

Retina Thinning Linked to Parkinson’s Disease: Potential Diagnosis via Optical Coherence Tomography (2024 Study)

by

Optical coherence tomography (OCT) reveals significant retinal nerve fiber layer (RNFL) thinning in Parkinson’s disease (PD) patients, correlating with disease severity and suggesting OCT as a potential biomarker for PD diagnosis and monitoring. Highlights: RNFL Thinning: Parkinson’s disease patients exhibit significant thinning of the retinal nerve fiber layer (RNFL) compared to non-PD individuals (p = …
