The Claim
Plasma p-tau217 levels above 0.471 pg/mL are associated with a 0.828-point-per-year faster decline in MMSE scores over a 2.57-year period in older adults with cerebrovascular disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older adults with cerebrovascular disease, higher levels of p-tau217 in the blood are linked to a faster rate of cognitive decline measured by the MMSE test over 2.57 years.
See the scientific wording
Plasma p-tau217 levels above 0.471 pg/mL are associated with a 0.828-point-per-year faster decline in MMSE scores over 2.57 years in older adults with cerebrovascular disease, indicating that elevated p-tau217 predicts more rapid cognitive deterioration independent of baseline cognitive status.
Too much of a specific abnormal protein in the blood builds up in the brain, where it disrupts connections between nerve cells and causes them to die, leading to faster loss of memory and thinking skills.
What the research says
1 studyIn older people with brain blood vessel disease, those with higher levels of a specific protein (p-tau217) in their blood lost memory and thinking skills faster over time — and the study found this link even after accounting for how sharp they were at the start.
