摘要
Objectives To investigate the presence of cerebral amyloidopathy and its associations with performances on neurocognitive tests and clinical features in depressed elders with mild cognitive impairment (MCI). Methods/design In total, 94 older adults with concomitant MCI and some depressive symptoms were included in this study. Cerebral amyloidopathy was evaluated using F-18-florbetaben-positron emission tomography. A standardized neurocognitive test battery and brain magnetic resonance imaging (MRI) were administered to all subjects. We examined the Apolipoprotein E genotype using a polymerase chain reaction-based method. Results Among the 94 initial participants, seven participants were excluded because of failure to undergo MRI or complete the neuropsychological battery. Among 87 subjects, 45 elders (51.7%) had cerebral amyloidopathy and were classified as the concomitant depression and MCI with cerebral amyloid-accumulation-positive (CDAP) group; others were classified as the concomitant depression and MCI with cerebral amyloid-accumulation-negative (CDAN) group. Poorer performances on word list recall and constructional recall were observed in the CDAP group than in the CDAN group. Conclusions The results indicate that around half of older adults with concomitant MCI and some depressive symptoms might be prone to have Alzheimer dementia. Results of neurocognitive tests possibly aid in discerning the presence of cerebral amyloidopathy.
