TL;DR: Among 112 older adults in Spain with mild cognitive impairment, those who reported more physical activity and felt more supported by family and friends scored better on several thinking tests. The study took one snapshot, so it cannot show that activity or support protects thinking. Key Findings 112 adults, average age 71: All had …
TL;DR: People with a common type of heart failure scored lower on thinking tests than healthy people of similar age, and an MRI sign of the brain’s fluid-clearing system was lower on the left side of their brains. Lower values of that sign went with lower thinking scores. Key Findings Lower thinking scores: Average MoCA …
TL;DR: In 86 people from one hospital in China, those with Parkinson’s and mild thinking problems showed changes in how water moves through parts of the hippocampus, a memory center. The hippocampus was not measurably smaller, suggesting a diffusion scan may pick up changes that size alone misses. Key Findings No size difference: None of …
Blood GFAP Started Mirroring the Brain Only After the BBB Leaked TL;DR: Blood biomarkers mostly failed to mirror the brain while the blood-brain barrier stayed intact; once the barrier leaked, glial fibrillary acidic protein (GFAP), an astrocyte injury protein, and inflammatory signals started lining up across blood and cerebrospinal fluid (CSF), the fluid surrounding the …
Cannabis Did Not Just Blur Word Lists. It Hit Everyday Memory Too TL;DR: A randomized vaporized-THC trial found broad acute memory impairment, including false memories, prospective memory, source memory, and temporal order memory, with no meaningful dose split between 20 and 40 mg. Key Findings 120 regular cannabis users randomized: Participants vaporized placebo cannabis, 20 …
Blood Test Detects Alzheimer’s with 83% Accuracy TL;DR: A new blood test using three misfolded plasma proteins can identify Alzheimer’s disease with 83.44% accuracy, outperforming conventional biomarkers and offering a non-invasive screening tool years before cognitive symptoms appear. The holy grail of Alzheimer’s research isn’t a cure—yet. It’s catching the disease before memory starts to …
Extended intra-nasal insulin (INI) treatment in an insulin-resistant early Mild Cognitive Impairment (MCI) patient improved grey matter volume, reduced beta-amyloid levels, and enhanced cognitive and pragmatic capacities, suggesting potential to slow neurodegenerative disease progression. Highlights: Grey Matter Volume: After 9 months of INI treatment, the patient experienced an increase in grey matter volume. Beta-Amyloid Levels: …
TLDR: Researchers demonstrated that intranasal administration of the peptide FITC-PHDP5-CPP reverses early cognitive impairment in Alzheimer’s disease (AD) model mice, showing potential as a treatment for AD-associated cognitive decline. Highlights: PHDP5, derived from the pleckstrin homology domain of dynamin 1, inhibits the interaction between dynamin and microtubules, rescuing synaptic dysfunction caused by tau accumulation. The …
People struggling with substance use disorders often have difficulties with memory, attention, planning, and decision-making. New research explores how these cognitive deficits relate to treatment outcomes and whether targeting them could improve addiction recovery. Key Facts: Cognitive deficits are common in people with substance use disorders, especially relating to memory, attention, self-control, and reward-based decision-making. …
Pesticides are chemicals commonly used worldwide to control unwanted organisms and disease vectors. However, research shows that chronic pesticide exposure may impair brain health and contribute to neurodegenerative diseases like Parkinson’s and Alzheimer’s. Key facts: Pesticides like organochlorines, organophosphates, pyrethroids, and mitochondrial complex I inhibitors can damage neurons and brain cell function through mechanisms like …
