Parkinson's disease (PD) is characterized by typical motor symptoms. However, recent studies show several non-motor features that may precede the development of the motor symptoms of PD. The best known premotor symptoms include hyposmia, REM sleep behavior disorder (RBD), constipation, and depression; other symptoms are excessive daytime somnolence, orthostatic hypotension and symptomatic hypotension, erectile or urinary dysfunction, musculoskeletal symptoms, pain, and global cognitive deficit. In this review, we summarize currently available diagnostic methods for these symptoms. We also briefly summarize neuroimaging, polyneuropathy, peripheral markers, and cerebrospinal fluid biomarkers that may be used in the early diagnosis of PD.

INTRODUCTION: Clusterin, a heterodimeric glycoprotein, is thought to be involved in many cellular functions, including cell-cell interaction, cell survival and apoptosis. In the brain, post-mortem analysis has found increased clusterin associated with the pathology of many other neurodegenerative diseases (ND) such as Parkinson's disease (PD), dementia with Lewy bodies (DLB), Alzheimer's disease (AD) and multiple system atrophy (MSA). In vivo cerebrospinal fluid (CSF) levels of clusterin in ND diseases may reflect differences in the pathology and thus aid in the differential diagnosis. METHODS: CSF levels of clusterin were assessed in 102 patients with clinical manifestations of neurodegenerative diseases (23 patients with PD, 18 with PDD, 15 with DLB, 18 with AD, 16 with PSP, 12 with MSA) and 21 subjects as a control group (CG). RESULTS: Significantly higher CSF clusterin levels were found in PD compared to CG (median 6884 vs. 4484; p=0.012), DLB (median 6884 vs. 4192; p=0.023), MSA (median 6884 vs. 3606; p=0.001) and PSP (median 6884 vs. 4193; p=0.014). Significantly higher CSF clusterin levels were found in PDD compared to CG (median 8617 vs. 4484; p=0.045), DLB (median 8617 vs. 4192; p=0.025) and MSA (median 8617 vs. 3606; p=0.004). CONCLUSION: The results of the presented "feasibility" study support the role of clusterin in PD/PDD pathogenesis. Clusterin CSF levels could serve as a potential marker for PDD and DLB differentiation.

An association between the CSF chromogranin A (CgA) and orthostatic blood pressure changes was investigated in 20 patients in the early stage of Parkinson disease (PD). There was a positive correlation between the CSF CgA and diastolic blood pressure change, when CSF CgA levels were lower in patients with orthostatic hypotension (OH). Decreased CSF CgA may be useful in predicting OH in the early stage of PD.

BACKGROUND: Parkinson's disease (PD), PD with dementia (PDD) and Lewy body dementia (DLB) are synucleinopathies. PDD and DLB are sometimes considered a transition between PD and Alzheimer dementia (AD). Finding in vivo markers or their combination could help in the differential diagnosis of these neurodegenerative (ND) diseases. OBJECTIVE: The aim of this study was to assess cerebrospinal fluid (CSF) levels of tau protein, betaamyloid1-42 and clusterin and to compare these levels among patients with probable PD, PDD, DLB and AD. METHODS: CSF levels of ND markers were assessed in 96 patients (27 patients with PD, 14 with PDD, 14 with DLB, 17 with AD and 24 subjects as a control group). RESULTS: In all of the groups of patients, beta-amyloid1-42 levels were decreasing in the order PD>PDD>DLB>AD, whereas tau protein and the tau protein/beta-amyloid1-42 index were increasing in the same order (PD
