Medication beliefs are a significant determinant of medication adherence in chronic illness. This study aimed to identify demographic, clinical, and medication-related factors associated with medication beliefs in patients with Parkinson’s disease (PD).
We used a descriptive cross-sectional design with a convenience sample of 173 PD patients who had been taking antiparkinson drugs for more than one year.
The subjects who believed PD medication was more necessary had more severe illness, younger age of onset, longer illness duration, and longer duration of levodopa therapy. They had higher levels of non-motor symptoms and depression, number of medication uses, number of drugs, and levodopa equivalent dose, and they reported fluctuation of motor symptoms and dyskinesia. The subjects who used catechol-O-methyltransferase (COMT) inhibitors, dopamine agonists, amantadine, and monoamine oxidase-B (MAO-B) inhibitors had significantly higher necessity scores than those who did not use them. The subjects who had higher concerns about PD medications had higher levels of non-motor symptoms and depression. The subjects using amantadine and anticholinergics had significantly higher concern scores than those who did not use them. Positive necessity-concerns differentials were associated with severe illness, the presence of motor fluctuation and dyskinesia, and the use of COMT inhibitors. Based on stepwise multiple regression, the most significant factors influencing necessity beliefs were severe illness, followed by depression and motor fluctuation.
Severe illness, higher levels of depression, and motor fluctuation are independent factors influencing patients’ beliefs regarding medication necessity. Therefore, these characteristics should be considered in medication belief assessment and interventions for PD patients.

AbstractAbstract PDF
The long-term effects of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) on postural instability and gait difficulty (PIGD) in patients with Parkinson’s disease (PD) remain unclear. In this study, we aimed to evaluate the longterm effects of STN-DBS surgery on PIGD symptoms in patients with advanced-stage PD. Methods This study included 49 consecutively included patients with PD who underwent bilateral STN-DBS. The Unified Parkinson’s Disease Rating Scale (UPDRS) scores and subscores for PIGD were assessed at baseline and at 1, 3, and 5 years postoperatively. The PIGD subscore was divided into PIGD-motor and PIGD-activities of daily living (ADL) scores according to parts III and II of the UPDRS, respectively. Results The PIGD-motor and PIGD-ADL scores at the “medication-off” state improved at 3 and 5 years, respectively. Overall, the UPDRS III and II scores at “medication-off” improved at 5 years. The UPDRS IV score also significantly improved and the levodopa equivalent daily dosage decreased at all follow-ups. Finally, the PIGD-motor score at baseline was able to predict long-term improvement in the PIGD-motor score at the 5-year follow-up. Conclusion The STN-DBS has both short- and long-term effects on PIGD, as well as overall motor function, in patients with advanced PD. The degree of PIGD at the preoperative evaluation can be used to predict long-term outcomes after STN-DBS surgery.

AbstractAbstract PDF

Various nonpharmacologic managements are important fundamental elements in the treatment of Parkinson’s disease (PD). We aimed to investigate the role of telephone counseling in managing PD patients.


From November 2006 to January 2007, we studied 243 PD patients at outpatient clinic of Asan Medical Center. Detailed telephone counseling was provided using a list structured questionnaires.


There were 73 men and 170 women with an age range of 17 to 85 years (mean age, 64.9 years). Mean age at onset was 59.5 years (range, 14–82 years) and mean disease duration was 5.6 years (range, 0.3–25 years). The contents of telephone counseling included adverse effects of anti-Parkinsonian medications (24.4%), aggravation of motor symptoms (18.7%), problems due to comorbidities (17.8%), how to take medicine (13.6%), activities of daily living (diet, bowel, sleeping and safety) (12.6%), complementary or alternative medicines (3.9%) and knowledge about PD (3.0%). Persons who responded to use the telephone counseling included patients (37.9%), offspring (36.2%), spouses (17.7%) and other relatives (7.4%). Persons who received the telephone counseling were determined by level of education, sex, cohabitation and Hoehn-Yahr stage. Contents of telephone counseling varied significantly with Hoehn-Yahr stage and persons who used the telephone counseling.


Our results suggest that support system with telephone counseling may provide beneficial therapeutic intervention in PD patients, especially for those with advanced PD. The most cost-effective method for telephone support needs to be studied.
