Serum brain-derived neurotrophic factor, nerve growth factor and neurotrophin-3 levels in dementia

The aim of this study is to measure serum levels of neurotropic factor (NF) in patients with dementia. Brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), and neurotrophin-3 (NT-3) were determined in Alzheimer's dementia patients without medication (AD; n: 22), Alzheimer's dementia patients receiving cholinesterase inhibitor (CEI) treatment (AD?+?CEI; n: 32) and vascular dementia patients receiving CEI treatment (VaD?+?CEI; n: 27) and the age-matched control group (n: 20). NGF levels were detected to be significantly higher in the control group than in AD group (P?
