Previously we suggested that major depression (MD) in Parkinson's disease (PD) could be an indication of a more advanced and widespread neurodegenerative process, as PD symptoms were more severe in those with depression. We also found a different antidepressant response with SSRI medication in PD patients with depression compared to depressed patients(More)
Both tau and beta-amyloid 42 (Abeta42) have been implicated in Alzheimer's disease (AD) and tau alone in frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). These proteins can be measured in the cerebrospinal fluid (CSF); differences from normal CSF levels may reflect pathophysiological mechanisms. Using ELISAs, we investigated the levels(More)
The biochemical basis of major depression (MD) in Parkinson's disease (PD) is largely unknown. To increase our understanding of MD in PD patients, the levels of monoamine metabolites (HVA, 5-HIAA and MHPG), BDNF, orexin-A, IL-6 and corticosterone were examined in cerebrospinal fluid. The analyses were performed in MD patients with (n = 11) and without (n =(More)
The CSF and sera of 7 patients with Parkinson's disease were investigated immunocytochemically, in order to see if antibodies were present which recognized DA-ergic cell bodies in glutaraldehyde fixed rat brain. In 2 patients a marked labeling of DA-ergic neurons in the substantia nigra was observed, identified by anti-DA antiserum and by 6-OHDA induced(More)
