"Pre-Dementia Cognitive Changes: A Precursor to Decline"

Researchers have identified a key deficit in individuals with amnestic mild cognitive impairment (aMCI) related to producing complex language, independent of the memory deficit characterizing this group, which may serve as a cognitive biomarker for early detection of dementia. The study found that aMCI patients struggled with processing ambiguous sentences involving pronouns, indicating a breakdown at the higher level of integrating form and meaning in language processing. These findings could potentially aid in early detection and treatment of dementia, as well as inform neuroscience studies and linguistics theory.
