Video Game Addiction vs. Brain Activity & Response Inhibition: A Cued Go/NoGo Task Study

by

Video game addiction (VGA) is associated with significant deficits in response inhibition and preparatory processes, reflected by more commission errors and reduced N2 amplitudes in the cued Go/NoGo task. Highlights: Increased Commission Errors: Individuals with VGA made significantly more commission errors in NoGo trials compared to healthy controls, indicating impaired response inhibition. Faster Reaction Times: …

Omega-3 Fatty Acids & Souvenaid® May Slow Cognitive Decline in Alzheimer’s Disease (2024 Review)

by

Omega-3 supplements and Souvenaid® show potential in slowing cognitive decline in Alzheimer’s patients, though the evidence remains inconclusive. Highlights: Cognitive Decline Reduction: The CDR scale showed a significant reduction in cognitive decline progression with Omega-3 supplementation (SMD = −0.4127, 95% CI: [−0.5926; −0.2327]). Mixed Cognitive Outcomes: 58% of studies reported positive cognitive effects from Omega-3 …

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 < …

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 …

High Stress in Midlife Linked to Dementia in Women (2024 Study)

by

Women experiencing midlife stress-related exhaustion have a higher risk of developing dementia at a younger age and exhibit long-term cognitive impairments. Highlights: Higher Dementia Risk: Women with midlife stress-related exhaustion had a nearly threefold increased risk of developing dementia before age 75. Earlier Onset: The average age of dementia onset was younger for women with …

Fidgeting May Enhance Attention in Adults with ADHD During Cognitively Demanding Tasks (2024 Study)

by

Fidgeting in adults with ADHD may serve as a compensatory mechanism to sustain attention during cognitively demanding tasks, particularly during correct task performance and when reaction time variability is low. Highlights: Fidgeting was significantly higher during correct trials compared to incorrect trials, suggesting it may aid in task performance. Increased fidgeting was observed in later …

Selegiline Reverses Anxiety & Memory Impairment in Amyloid Beta-Induced Alzheimers Model Rats (2024 Study)

by

The study demonstrated that selegiline (SEL) improves memory performance, reduces anxiety, and modulates oxidative stress in an Alzheimer’s disease (AD) rat model. Highlights: Memory Improvements: SEL administration improved recognition memory, spatial memory, and passive avoidance memory in AD rats. Anxiety Reduction: SEL significantly reduced anxiety-like behavior in AD rats, as evidenced by performance in the …
