5-Hydroxyindoleacetic acid and homovanillic acid concentrations in cerebrospinal fluid in patients with Alzheimer's disease, depression and mild cognitive impairment.
: In this study we investigated the cerebrospinal fluid (CSF) concentrations of 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) in Alzheimer (AD) patients (n=75), patients with mild cognitive impairment (MCI, n=9) and patients with depression (n=7).
