To identify biomarkers associated with cognitive stimulation of mild cognitive impairment (MCI) patients, we performed quantitative real-time reverse transcriptase polymerase chain reaction for brain-derived neurotrophic factor (BDNF) mRNA in peripheral lymphocytes of MCI and healthy subjects undergoing a multi-component cognitive training (CT) program. CT determined a significant decrease of BDNF mRNA levels in MCI (fold […]
