  • Objectives: This study investigated how income, duration of illness, social stigma, quality of sleeping, ADL and social participation related to Parkinson's disease(PD) predict depression in a conceptual model based on the International Classification of Functioning(ICF) model. Methods: The sample included 206 adults with idiopathic Parkinson's disease(IPD) attending D university hospital in B Metro-politan City. A structured questionnaire was used and conducted face-to-face interviews. The collected data were analyzed for fitness, using the AMOS 18.0 program. Results: A path analysis showed that the overall model provided empirical evidence for linkages in the ICF model. Depression was manifested by significant direct effects of social stigma(${\beta}=.20$, p<.001), quality of sleeping(${\beta}=-.40$, p<.001), ADL(${\beta}=-.20$, p<.01), and social participation(${\beta}=-.12$, p<.05), indirect effects including income(p<.05), duration of illness(p<.05). These variables explained 45.9% of variance in the prediction model. Conclusions: This model may help nurses to collect and assess information to develop intervention program for depression.

  • After the first research declaring the generation of human induced pluripotent stem cells (hiPSCs) in 2007, several attempts have been made to model neurodegenerative disease in vitro during the past decade. Parkinson's disease (PD) is the second most common neurodegenerative disorder, which is mainly characterized by motor dysfunction. The formation of unique and filamentous inclusion bodies called Lewy bodies (LBs) is the hallmark of both PD and dementia with LBs. The key pathology in PD is generally considered to be the alpha-synuclein (${\alpha}$-syn) accumulation, although it is still controversial whether this protein aggregation is a cause or consequence of neurodegeneration. In the present work, the recently published researches which recapitulated the ${\alpha}$-syn aggregation phenomena in sporadic and familial PD hiPSC models were reviewed. Furthermore, the advantages and potentials of using patient-derived PD hiPSC with focus on ${\alpha}$-syn aggregation have been discussed.

  • The objective of this study was to produce a nutrient delivery system (NDS) using sialic acid extracted from edible bird's nest (EBN), which improves brain function in patients with Alzheimer's disease and Parkinson's disease, by affinity bead technology (ABT). The inhibitory activity of acetylcholinesterase (AChE) and pyramidal cells in the dentate gyrus of the hippocampus were analyzed to investigate the effect of a sialic acid NDS on Alzheimer's disease. Also, the effect of a sialic acid NDS on Parkinson's disease was evaluated by rota-rod test and pole test in an animal model. Among the groups treated with donepezil, EBN, and sialic acid NDS, the AChE activity was the lowest in the sialic acid NDS-treated group. The results of the hippocampus analysis of the rat model confirmed that the sialic acid NDS inhibited amyloid-beta accumulation depending upon the concentration. Also, the sialic acid NDS group showed more improvement in motor deterioration than the1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced group in both the rota-rod test and pole test. Therefore, the sialic acid NDS had an effect of protecting not only Alzheimer's disease by inhibiting AChE and amyloid-beta accumulation, but Parkinson's disease by preventing neurotoxicity induced by MPTP.

  • The concentration effect relationship (pharmacokinetic pharmacodynamic model, PKPD) of drugs used for Parkinson's disease is complex. The benefits and adverse effects of drug treatment have to be considered in terms of short term and long term effects. Acute effects, observed over hours and days, reflect symptomatic benefit while chronic effects, observed over months and years, also reveal influences on the progress of the disease. (omitted)

  • Purpose: The study was done to identify lower urinary tract symptoms (LUTS) and to evaluate the factors affecting LUTS for the people with Parkinson's disease. Methods: The research design was a cross-sectional study with interviews using a structured questionnaire. The participants were 72 patients with Parkinson's disease who were seen in the Neurology clinic of a university hospital from September to November 2005. Results: Mean score of LUTS for the participants was 10.11. In each symptom score of LUTS (range 0-5), weak stream was the highest 2.06, followed by nocturia 1.71, and urgency 1.61. The severity of LUTS was moderate to severe group for 51%. LUTS were significantly different by regular exercise. Positive correlations were observed between Hoehn and Yahr stage (stage of disease severity) and frequencyand between Hoehn and Yahr stage and urgency (r=.280, p=.018; r=.328, p=.005). LUTS were significantly predicted by regular exercise (p=.001) which explained 15.0% of the variance in LUTS. Conclusion: Regular exercise was found to be a very important factor associated with LUTS for patients with Parkinson's disease.

  • Background : Qigong is an exercise therapy based on the principles of Traditional East Asian Medicine. The exercises combine the practice of motion and breathing, both guided by mental imagery. Beneficial effects of qigong have been reported on a variety of complaints in chronically ill patients and on gait imbalance in the elderly. Parkinson's disease is a progressive neurodegenerative disorder that affects neurophysiological function, movement abilities, and quality of life. Objectives : We developed a qigong program based on the Traditional East Asian medical theory regarding the improvement of clinical symptoms of Parkinson's disease. Methods and Results : Our qigong program consists of three parts. The first one includes movements which stimulate the meridians that run from the toes to the top of the head. The second one is composed of breathing and qigong movements that create harmony and balance with the circulation of Qi and blood on the Meridians. The third is a stage of finger pressure therapy and massage from Daoyin medical qigong to maintain meridian stability. Conclusions : These qigong program would help relieve the clinical symptoms of Parkinson's disease patients.

  • Purpose: Investigation of the quality of life (QoL), family support and associated variables in patients with Parkinson's disease. Methods: The data were collected from 102 patients registered in the neurology department of C University Hospital. QoL was assessed using the Parkinson's Disease Questionnaire (PDQ-39) and Family Support Scale. Modified Hoehn and Yahr (H & Y) stages were obtained from an interview and clinical examination by a neurologist. Collected data were analyzed using the SAS program. Results: The participants' PDQ-39 average score was 34.34. The scores were significantly higher for participants who were older, who had a job and who were over 2.5 on the H & Y stage. The average for Family support scores was 41.6. Participants who had a living spouse, religion and a job scored higher than those who did not. PDQ-39 score had a positive correlation with age, job, and H & Y stage. Family support and PDQ-39 score were also positively correlated. Conclusion: It is recommended a program involving family that improves family support and be developed and that it be varied according to different H & Y stages, in order to improve QoL.

  • Objective: The study aimed to develop a functional performance index that evaluates the functional performance of Parkinson's patients, i.e., to integrate biomechanical measurements of walking, balance, muscle strength and tremor, and to use multiple linear regression with stepwise methods to identify the most suitable predictors for the progression of disease. Method: A total of 60 subjects were tested for sub-variables of four factors: walking, balance, isometric strength and hand tremors. Potential independet variables were extracted through correlation analysis of the sub-variables and dependent variables, Hoehn & Yahr scale. And then, a stepwise multiple regression analysis using the potential independent variables was performed to identify predictor of Hoehn & Yahr scale. Results: First, the results of the study showed that physical composition and gait had a relatively more correlated with the progression of the disease, compared to balance and hand tremor. Second, Parkinson's functional performance is characterized by dynamic pattern of walking, such as foot clearance and turning angle (TA) of walking, and a high-explained regression model is completed. Conclusion: The study emphasized the importance of walking variables and body composition in minor pathological features compared to Parkinson's patient's balancing ability and hand tremor. Specifically, it revealed that dynamic walking patterns functionally characterize patients. The results are worth considering when assessing functional performance related to the progression of the disease at the site.

  • The purpose of this study was to quantify the clinical assessment of rigidity at wrist in patients with Parkinson's disease. The experimental system was designed that the effect of gravity was negated by restricting motion at the horizontal plane and inertia was predetermined from a biomechanical measurement. Forty five patients with Parkinson's disease participated in this study. Viscoelastic properties were calculated from the experimental data acquired during intermittent passive movement of wrist. Viscoelastic constants correlated well with the rigidity scores of UPDRS, i.e., Spearman's r=0.733 and 0.905 for spring and damping constants, respectively. The results suggest that viscoelastic properties can be used as quantitative measures of rigidity.
