Higher Serum Lutein and Zeaxanthin Levels Associated with a Lower Risk of All-Cause Dementia
Written by Taylor Woosley, Staff Writer. Study findings using data from the NHANES III Survey (1988-1994) show that serum lutein+zeaxanthin was associated with a reduced risk of all-cause dementia, with an inverse relationship being noted between serum β-cryptoxanthin and all-cause dementia. (more…)
Higher Vitamin K Intake Associated with Reduced Risk of Dementia-Related Cognitive Impairment
Written by Taylor Woosley, Staff Writer. Results of the MAP longitudinal study show that higher brain MK4 concentrations in all four brain regions resulted in a 17% to 20% lower chance of dementia or mild cognitive impairment occurrence (ORs 0.80 to 0.83, all P-values < .014). (more…)
Blueberry Consumption Improves Cognitive Executive Control in Insulin-Resistant Adults
Written by Taylor Woosley, Staff Writer. 12-week supplementation with blueberry powder (equivalent to 0.5 c of blueberries) resulted in significant improvement in lexical access and a reduction of recall intrusion errors, with a significant decline in fasting insulin noted at the 12-week mark. (more…)
Aronia melanocarp Supplementation Improves Psychomotor Speed
Written by Chrystal Moulton, Staff Writer. 24-week supplementation with 90 mg Aronia melanocarpa resulted in significantly improved psychomotor functioning (p= 0.009). Supplementation of 150 mg Aronia melanocarpa showed no further increase in psychomotor skills but significant improvements in diastolic blood pressure were noted. (more…)
Phenylindane, a Bioactive Compound Found in Coffee, Exhibits Neuroprotective Properties Against Age-Related Cognitive Decline Disorders
Written by Taylor Woosley, Staff Writer. Results of the study suggest high levels of phenylindane, a bioactive compound found in coffee, may offer neuroprotective properties against age-related cognitive disorders through the dual inhibition of Aβ and tau aggregation. (more…)
B Vitamin Supplementation Improves Overall Cognitive Functioning in Non-Aspirin Users
Written by Taylor Woosley, Staff Writer. Findings suggest B-vitamin supplementation provides superior neuroprotective properties, particularly in its ability to reduce the rate of whole brain atrophy, in non-aspirin users compared to participants taking B-vitamins and aspirin. (more…)
Daily Peanut Consumption Associated with Improved Memory and Decreased Levels of Stress and Anxiety
Written by Taylor Woosley, Staff Writer. Results of the study show that after six months of daily peanut consumption participant’s polyphenol and short-chain fatty acid levels significantly increased, resulting in lower anxiety, depression, and cortisol scores, while also resulting in improvement in immediate memory. (more…)
Overconsumption of Sugar Shown to Have Lasting Effects on the Brain
Written by Jessica Patella, ND. Study results suggest that long-term, high-sugar consumption of the Western diet may play a role in attention deficits and hyperactivity disorders into adulthood. (more…)
Melatonin Regulates Daytime Learning Efficiency in Mice
Written by Angeline A. De Leon, Staff Writer. Study findings suggest that melatonin does indeed play a role in shaping time-of-day-dependent learning efficiency in mammals. (more…)
Possible Therapeutic Effects of Cannabidiol on Memory and Cognitive Function
Written by Chrystal Moulton, Staff Writer. Compared to delta-9-tetrahydrocannabinol (THC) inhaled alone or in combination with cannabidiol (CBD), inhaled CBD demonstrated a reduction in psychotic-like symptoms in light users of cannabis.
