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 …

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 < …

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 = …

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 …

Occlusion Dysfunction (OD) Causally Linked to Alzheimer’s Disease (2024 Study)

by

Occlusion dysfunction (OD) is causally linked to an increased risk of Alzheimer’s disease (AD), while dentures restoration can mitigate this risk. Highlights: Periodontal disease (PD) and Alzheimer’s do not have a direct causal relationship (P = 0.395). Loose teeth significantly increase the risk of AD progression (P = 0.017, OR = 187.3567). Dentures restoration is …

Necrostatin-1: A Necroptosis Inhibitor to Treat Neurological Disorders (2024 Research)

by

Necrostatin-1, an inhibitor of necroptosis, exhibits significant neuroprotective effects and potential therapeutic applications in various neurological disorders by modulating cell death pathways, inflammation, and reactive oxygen species. Highlights: Mechanism of Action: Necrostatin-1 specifically inhibits receptor-interacting protein 1 (RIP1), preventing necroptosis and other cell death pathways, including apoptosis and ferroptosis. Neuroprotective Role: It shows promise in …

Novel Risk Genes for Schizophrenia Discovered in High Altitude Tibetans via Whole-Exome Sequencing (2024 Study)

by

A study on Tibetans living at high altitudes identified novel risk genes for schizophrenia (SCZ) related to hypoxia, suggesting a unique genetic signature for SCZ in this population. Highlights: Whole-exome sequencing of 47 SCZ cases and 53 controls in Tibetans revealed 275 potential novel risk variants and two known variants. One gene, C5orf42, surpassed exome-wide …

PCSK9 Inhibitors May Increase Parkinson’s Disease & Reduce ALS Risk (2024 Study)

by

PCSK9 inhibitors significantly reduce the risk of amyotrophic lateral sclerosis (ALS) but increase the risk of Parkinson’s disease (PD). Highlights: ALS Risk Reduction: PCSK9 inhibitors marginally reduced the risk of ALS with an odds ratio of 0.89 (p = 0.048). PD Risk Increase: PCSK9 inhibitors increased the risk of Parkinson’s disease, with an odds ratio …
