Blodprøve kan afsløre tegn på Alzheimers år i forvejen

Et nyt studie viser, at blodprøver kan detektere tegn på Alzheimers flere år før sygdommen udvikler sig. Amerikanske forskere har publiceret resultaterne i The Lancet.

Amerikanske forskere undersøgte blodprøver fra 1.350 personer uden demens med en gennemsnitsalder på 61 år i et studie publiceret i The Lancet. Niveauerne af proteinet fosforyleret tau viste sig at stige allerede i 60-års alderen.

86 deltagere havde forhøjede niveauer og klarede sig dårligere i kognitive tests. Disse individer oplevede også en hurtigere forværring ved opfølgninger hvert femte år.

Henrik Zetterberg ved Göteborgs Universitet siger, at blodprøven er enklere end de nuværende metoder. Han understreger, at der ikke er grund til generel testning i dag, da effektive behandlinger mangler i Sverige.

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 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.

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.

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.

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.
