Abstract
Levodopa (L-3,4-dihydroxyphenylalanine, L-Dopa) alleviates the symptoms of Parkinson's disease (PD), yet prolonged usage may give rise to severe adverse effects. Resveratrol (RSV) is a potent antioxidant, anticancer and anti-inflammatory agent. And a variety of polyphenol antioxidant compounds derived from RSV combined with levodopa have demonstrated neuroprotective activity against neuronal cell death. The purpose of this study was to examine the impact of this combination of RSV and L-Dopa on the survival rate, growth status, and reactive oxygen species (ROS) of MES23.5 dopamine (DA) neuron cells. In this study, we induced MPP+ in MES23.5 dopamine neuron cells and observed their survival rate, growth status, ROS content, as well as the effect of RSV combined with L-Dopa on cell survival. We also measured malondialdehyde (MDA) levels and superoxide dismutase (SOD) activity levels as indicators of mitochondrial function, oxidative stress, and oxidative damage in the cells. Our results indicated that the MES23.5 dopamine neurons had decreased survival, poor growth status, and increased ROS content after MPP+ induction. Moreover, we found that MDA levels were elevated, and SOD activity levels were decreased, suggesting that the cells experienced abnormal mitochondrial function. However, when RSV was combined with L-Dopa, the cells showed a reduced level of MPP + -induced oxidative damage, with a more significant inhibitory effect observed in the RSV group at a concentration of 50 μmol/L. In conclusion, we found that the effects of co-administration of RSV with L-Dopa (100 μmol/L) was more effective than L-Dopa administered at the high dose. Thus, we found that RSV has the potential to reduce the dose of L-Dopa required to improve PD symptoms.

Natural history of motor symptoms in Parkinson's disease and the long-duration response to levodopa. Brain 2020; 143:2490-2501. [PMID: 32844196 PMCID: PMC7566883 DOI: 10.1093/brain/awaa181] [Citation(s) in RCA: 86] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 04/01/2020] [Accepted: 04/14/2020] [Indexed: 01/05/2023] Open
Abstract
The natural pattern of progression of Parkinson’s disease is largely unknown because
patients are conventionally followed on treatment. As Parkinson’s disease progresses, the
true magnitude of the long-duration response to levodopa remains unknown, because it can
only be estimated indirectly in treated patients. We aimed to describe the natural course
of motor symptoms by assessing the natural OFF in consecutive Parkinson’s disease patients
never exposed to treatment (drug-naïve), and to investigate the effects of daily levodopa
on the progression of motor disability in the OFF medication state over a 2-year period.
In this prospective naturalistic study in sub-Saharan Africa, 30 Parkinson’s disease
patients (age at onset 58 ± 14 years, disease duration 7 ± 4 years) began levodopa
monotherapy and were prospectively assessed using the Unified Parkinson’s disease Rating
Scale (UPDRS). Data were collected at baseline, at 1-year and 2-years follow-up.
First-ever levodopa intake induced a significant improvement in motor symptoms (natural
OFF versus ON state UPDRS-III 41.9 ± 15.9 versus 26.8 ± 15.1, respectively;
P < 0.001). At 1-year follow-up, OFF state
UPDRS-III score after overnight withdrawal of levodopa was considerably lower than natural
OFF (26.5 ± 14.9; P < 0 .001). This effect was not
modified by disease duration. At the 2-year follow-up, motor signs after overnight OFF
(30.2 ± 14.2) were still 30% milder than natural OFF
(P = 0.001). The ON state UPDRS-III at the first-ever
levodopa challenge was similar to the overnight OFF score at 1-year follow-up and the two
conditions were correlated (r = 0.72,
P < 0.001). Compared to the natural progression of
motor disability, levodopa treatment resulted in a 31% lower annual decline in UPDRS-III
scores in the OFF state (3.33 versus 2.30 points/year) with a lower model’s variance
explained by disease duration (67% versus 36%). Using the equation regressed on
pretreatment data, we predicted the natural OFF at 1-year and 2-year follow-up visits and
estimated that the magnitude of the long-duration response to levodopa ranged between 60%
and 65% of total motor benefit provided by levodopa, independently of disease duration
(P = 0.13). Although levodopa therapy was associated
with motor fluctuations, overnight OFF disability during levodopa was invariably less
severe than the natural course of the disease, independently of disease duration. The same
applies to the yearly decline in UPDRS-III scores in the OFF state. Further research is
needed to clarify the mechanisms underlying the long-duration response to levodopa in
Parkinson’s disease. Understanding the natural course of Parkinson’s disease and the
long-duration response to levodopa may help to develop therapeutic strategies increasing
its magnitude to improve patient quality of life and to better interpret the outcome of
randomized clinical trials on disease-modifying therapies that still rely on the overnight
OFF to define Parkinson’s disease progression.

Acta Neurol Scand 2019; 140:157-161.

Abstract
BACKGROUND Few studies have suggested that levodopa-carbidopa intestinal gel (LCIG) may have a benefit on Parkinson's disease (PD) axial signs. AIMS OF THE STUDY To investigate the long-term effect of LCIG on axial signs and the related prognostic factors. METHODS A retrospective study on 49 PD patients treated with LCIG. Axial signs as per the Unified Parkinson Disease Rating Scale axial score (AS), Hoehn and Yahr (H&Y) scale, and levodopa equivalent daily dose (LEDD) were assessed at baseline (before starting LCIG treatment) and at the last follow-up (FU). RESULTS After 47.6 ± 30 months of treatment, total AS deteriorated while motor complications still improved, in spite of a significant LEDD/Kg increment. When adjusted for LCIG treatment duration, a higher AS and freezing of gait severity at FU were predicted by a baseline lower response to l-dopa and higher H&Y (P < 0.01) and they were related to a lower independency in activity of daily life at FU (P < 0.001). Single axial items remain stable up to one year and postural instability up to four years. CONCLUSION Baseline disease severity and the magnitude of l-dopa response predict axial signs' severity after around four years of LCIG treatment, with consequent implication on patients' functional independence.

Abstract
BACKGROUND Few data exist on the rate of clinical progression for Parkinson's disease (PD) patients who have entered a late stage of the disease. OBJECTIVE Study the clinical progression of a late-stage PD (LSPD) population over one year follow-up. METHODS 50 LSPD patients (Schwab and England ADL Scale <50 or Hoehn Yahr Stage >3 in MED ON) underwent an extensive clinical assessment at baseline and after one year and an acute levodopa test at baseline. RESULTS Mean age of LSPD patients (female 46%) was 77.5 ± 5.9 years and mean disease duration was 15.5 ± 6.5 years. At baseline, 76% had levodopa-induced motor complications (MC), usually non-troublesome, 68% were demented, 54% had psychosis and 68% depression. Caregiver distress was high. l-dopa responsiveness was mild (18% ± 12 of improvement on MDS-UPDRS-III). After one-year, 20% of the patients were dead, institutionalized or HY 5. MDS-UPDRS-motor mean score worsened 7.2 ± 10.3 points although there was heterogeneity between patients, and there was a global worsening of non-motor symptoms, mostly in cognition/mood, urinary and gastrointestinal domains. Nevertheless, MC improved despite similar levodopa equivalent dose. Functional independence and quality of life worsened. Dysphagia severity at baseline predicted a poor outcome (death, institutionalization or HY 5) (Hazard ratio 2.3, 95% CI 1.12-4.4; p = 0.01), whereas magnitude of l-dopa response of LSPD patients did not. CONCLUSIONS LSPD patients still present a significant, although heterogeneous, motor and non-motor progression over 1 year. Dysphagia severity predicts the occurrence of additional disease severity milestones and its management must be prioritized.

Abstract
In Parkinson's disease (PD), on-demand deep brain stimulation is required so that stimulation is regulated to reduce side effects resulting from continuous stimulation and PD exacerbation due to untimely stimulation. Also, the progressive nature of PD necessitates the use of dynamic detection schemes that can track the nonlinearities in PD. This paper proposes the use of dynamic feature extraction and dynamic pattern classification to achieve dynamic PD detection taking into account the demand for high accuracy, low computation, and real-time detection. The dynamic feature extraction and dynamic pattern classification are selected by evaluating a subset of feature extraction, dimensionality reduction, and classification algorithms that have been used in brain-machine interfaces. A novel dimensionality reduction technique, the maximum ratio method (MRM) is proposed, which provides the most efficient performance. In terms of accuracy and complexity for hardware implementation, a combination having discrete wavelet transform for feature extraction, MRM for dimensionality reduction, and dynamic k-nearest neighbor for classification was chosen as the most efficient. It achieves a classification accuracy of 99.29%, an F1-score of 97.90%, and a choice probability of 99.86%.
