En ny studie viser at blodprøver kan avdekke tegn på Alzheimers flere år før sykdommen utvikler seg. Amerikanske forskere publiserte funnene i The Lancet.

Amerikanske forskere undersøkte blodprøver fra 1 350 personer uten demens med en gjennomsnittsalder på 61 år i en studie publisert i The Lancet. Nivåene av proteinet fosforylert tau viste seg å stige allerede i 60-årene.

86 deltakere hadde forhøyede nivåer og presterte dårligere på kognitive tester. Disse individene viste også en raskere nedgang ved oppfølginger hvert femte år.

Henrik Zetterberg ved Göteborgs universitet sier at blodprøven er enklere enn dagens metoder. Han understreker at det ikke er noen grunn til bred testing i dag, ettersom effektive behandlinger mangler i Sverige.

Study finds blood-cancer-linked mutations in brain immune cells tied to Alzheimer’s pathology

Researchers at Boston Children’s Hospital report that mutations commonly associated with clonal blood-cell expansion and some blood cancers were enriched in microglia-like immune cells in Alzheimer’s brains and were also detectable in matched blood samples. The Cell study proposes that age- or injury-related weakening of the blood-brain barrier could allow mutated blood immune cells to enter the brain, potentially amplifying inflammation and contributing to neurodegeneration.

Women’s verbal memory may delay alzheimer’s diagnosis by years

Women maintain normal scores on standard memory tests for nearly three years longer than men even after Alzheimer’s-related brain changes begin. This cognitive advantage can mask early signs of the disease and delay treatment. A new analysis of long-term studies in the US and Canada highlights the issue.

Higher midlife vitamin D levels linked to lower brain tau protein

7. april 2026 Rapportert av AI

A new study has found that adults with higher vitamin D levels in their 30s and 40s tend to have lower levels of tau protein in their brains about 16 years later. Tau is a key biomarker associated with dementia. The research, published this week, highlights a potential modifiable risk factor for brain health.

Scientists restore memory in Alzheimer's mice by blocking PTP1B

Researchers at Cold Spring Harbor Laboratory have found that blocking the protein PTP1B improves memory and boosts plaque clearance in mouse models of Alzheimer's disease. The discovery links the protein to brain immune function and metabolic risks like diabetes and obesity. The team aims to develop inhibitors for potential human treatments.

Copper compound restores memory in Alzheimer’s lab tests

16. juni 2026 Rapportert av AI

A copper-based drug has shown potential to reduce toxic protein buildup and improve memory in laboratory models of Alzheimer’s disease. Researchers at Monash University found that the compound Cu(ATSM) enhanced the brain’s waste-clearing mechanisms. The results were published in ACS Chemical Neuroscience.
