Høyt kjøttinntak knyttet til lavere risiko for demens

Et høyt kjøttinntak kan redusere risikoen for demens hos eldre personer med genetisk disposisjon for Alzheimers, ifølge en studie fra Karolinska Institutet. Studien fulgte over 2100 personer i alderen 60 år og eldre i opptil 15 år. Funnene gjelder for bærere av spesifikke apoe-genvarianter.

En ny studie fra Karolinska Institutet, publisert i JAMA Network Open, har undersøkt sammenhengen mellom kjøttforbruk og kognitiv helse hos eldre voksne. Studien fulgte mer enn 2100 personer, alle i alderen 60 år eller eldre, i opptil 15 år. Deltakerne var bærere av apoe-genet, og rundt 70 prosent av Alzheimers-pasientene hadde kombinasjonene apoe 3/4 eller apoe 4/4, noe som indikerer genetisk risiko. Den kvintilen som spiste mest kjøtt, viste ingen forhøyet risiko for kognitiv svikt eller demens. Medianinntaket deres ble anslått til rundt 870 gram kjøtt per uke. "De som spiste mest kjøtt, hadde signifikant bedre kognitiv utvikling og lavere risiko for demens, men bare hvis de hadde genvariantene apoe 3/4 eller 4/4", sier Jakob Norgren, førsteforfatter av studien og forsker ved KI, i en uttalelse. Forskningen belyser hvordan kostholdet kan påvirke demensrisikoen hos personer med genetisk sårbarhet, selv om funnene er spesifikke for disse genbærerne.

Genetic study links lower cholesterol to reduced dementia risk

A large-scale genetic analysis of about 1.09 million people suggests that lifelong, genetically lower cholesterol—specifically non‑HDL cholesterol—is associated with substantially reduced dementia risk. Using Mendelian randomization to emulate the effects of cholesterol‑lowering drug targets such as those for statins (HMGCR) and ezetimibe (NPC1L1), the study found up to an approximately 80% lower risk per 1 mmol/L reduction for some targets.

A Swedish study suggests that consuming more high-fat cheese could lower dementia risk by 13%, based on data from nearly 30,000 people followed for 25 years. However, experts caution that it is an observational analysis without proof of causality. Critics highlight potential confounders and the importance of factors like blood pressure and weight control.

A 25-year Swedish study of nearly 28,000 people, published in Neurology, found that higher daily intake of full-fat cheese and cream was associated with a 13% to 24% lower risk of dementia—particularly in those without genetic predispositions—but not for low-fat dairy or those with genetic risks. The findings challenge low-fat dairy recommendations and emphasize overall healthy diets.

New research finds that blood biomarkers associated with Alzheimer’s disease increase significantly faster in people with obesity than in those without. Drawing on five years of data from 407 volunteers, the study suggests that blood tests can detect obesity‑related changes earlier than brain scans, underscoring obesity as a major modifiable risk factor for Alzheimer’s.

A large study of nearly 28 million older Americans has found that long-term exposure to fine particle air pollution increases the risk of developing Alzheimer's disease, primarily through direct effects on the brain. The research, led by Yanling Deng at Emory University, indicates that individuals with a history of stroke may face heightened vulnerability. Published in PLOS Medicine, the findings highlight the importance of cleaner air for protecting cognitive health in aging populations.

Researchers have identified the gene ADAMTS2 as significantly more active in brain tissue from African Americans with Alzheimer's disease, marking a potential shared biological pathway across racial groups. This finding emerges from the largest study of its kind using brain samples from over 200 African American donors. The gene's prominence also appeared in a separate analysis of White individuals, suggesting broader implications for treatment.

Researchers at the University of California, San Francisco, have discovered a mechanism by which exercise helps protect the brain from age-related damage associated with Alzheimer's disease. Physical activity prompts the liver to release an enzyme that repairs the blood-brain barrier, reducing inflammation and improving memory in older mice. The findings, published in the journal Cell, highlight a body-to-brain pathway that could lead to new therapies.
