Meanings of cognitively unimpaired in English

Results: Plasma total tau and pTau181 levels were higher in AD dementia patients than those in cognitively unimpaired.

The evolution of Alzheimer's disease tauopathy in cognitively unimpaired individuals needs to be examined to better understand disease pathogenesis.

Elevated tau signal was seen in regions that are considered high Braak Stage in cognitively unimpaired and cognitively impaired individuals.

More frequent regional tau signal elevation throughout the brain was seen in cognitively unimpaired individuals with abnormal versus normal amyloid.

We evaluated the findings of tau-PET to better understand neurofibrillary tangle development as it is seen in cognitively unimpaired and impaired individuals.

Objective: To test whether neighborhood-level socioeconomic disadvantage is associated with decreased brain volume in a cognitively unimpaired population enriched for Alzheimer disease risk.

Tau-PET was performed in 86 cognitively impaired individuals who all had abnormal amyloid levels and 601 cognitively unimpaired individuals.

Methods: The study included 1,535 cognitively unimpaired participants with multimorbidity, 11C-PiB positron emission topography and magnetic resonance imaging data available.

They were compared with 25 disease severity- and age-matched amnestic AD patients and a group of 131 cognitively unimpaired (CU) elderly individuals.
