Abstract

Studies on cerebrospinal fluid (CSF) monoamines in patients with Alzheimer's disease (AD) are conh·oversial. In this work, CSF concentrations of 3-methoxi-4-hydroxi-phenylethylgly­col (MHPG), 5-hydroxyindoleacetic acid (5-HTAA), homovanillic acid (HVA), and dihydroxyphenylacetic acid (DOPAC), metabo­lites of noradrenaline, seroconine and dopamine were measured by high performance liquid chromatography (HPLC) with electro­chemical dececcion. CSF was obtained from 18 patiems with AD and 16 subjects without neurological or psychiatric diseases, who underwent spi.nal aoesthesia. Significantly lower levels of CSF MHPG, HVA and 5-HIAA were observed in AD palients with re­spect to the control group. No changes in CSF DOPAC concentra­tion were demonstrated. CSF monoamine levels were not significamly associated with the severity of dementia. Studies of CSF monoamines in AD may provide further information for t.he paihophysiology of this disorder and offers the possibility of moni­toring neurotransmitter replacement therapies.
