Abstract: Patients with idiopathic Parkinson's disease (PD) may suffer from autonomic nervous system dysfunction even in the early phase of the disease.We assessed the autonomic cardiovascular and sudomotor regulation in de novo PD patients with and without medication.A freshly-made surface of obsidian (volcanic glass of rhyolitic composition) will absorb water which slowly penetrates by diffusion into the body of the artifact.Although the depth of penetration can be measured by various methods, it is generally determined by microscopic examination on thin sections of the artifact cut normal to the surface.We also measured the dopamine (DAT) and serotonin transporter (SERT) uptake in the PD patients using 2β-carboxymethoxy-3β-(4-iodophenyl)tropane (β-CIT) SPECT and studied the clinical correlates of the uptake.Sixty PD patients were included in the study and randomised to receive levodopa, bromocriptine or selegiline (n=20 in each) as their treatment. The results of the patients were compared with those of healthy controls and within the subgroups at different time points.
