Previous studies have suggested that mild cognitive impairment (MCI) may be reflective of the early stages of neurodegenerative disorders such as Alzheimer’s disease (AD). The hypothesis was that cytokeratin (CK) 14 expression can be used as a biomarker in isolated buccal mucosa to identify individuals with MCI or AD from the Australian Imaging, Biomarkers and Lifestyle (AIBL) flagship study of aging. Visual assessment of buccal cell CK14 expression was carried out using immunofluorescence techniques. The frequency of basal buccal cells expressing CK14 was significantly lower in the MCI (P=0.0002) and AD (P
