Nonmotor symptoms (NMS) of Parkinson's disease (PD) are not well recognized in clinical practice, either in primary or in secondary care, and are frequently missed during routine consultations. There is no single instrument (questionnaire or scale) that enables a comprehensive assessment of the range of NMS in PD both for the identification of problems and for the measurement of outcome. Against this background, a multidisciplinary group of experts, including patient group representatives, has developed an NMS screening questionnaire comprising 30 items. This instrument does not provide an overall score of disability and is not a graded or rating instrument. Instead, it is a screening tool designed to draw attention to the presence of NMS and initiate further investigation. In this article, we present the results from an international pilot study assessing feasibility, validity, and acceptability of a nonmotor questionnaire (NMSQuest). Data from 123 PD patients and 96 controls were analyzed. NMS were highly significantly more prevalent in PD compared to controls (PD NMS, median = 9.0, mean = 9.5 vs. control NMS, median = 5.5, mean = 4.0; Mann-Whitney, Kruskal-Wallis, and t test, P < 0.0001), with PD patients reporting at least 10 different NMS on average per patient. In PD, NMS were highly significantly more prevalent across all disease stages and the number of symptoms correlated significantly with advancing disease and duration of disease. Furthermore, frequently, problems such as diplopia, dribbling, apathy, blues, taste and smell problems were never previously disclosed to the health professionals.

Objectives: To accurately establish the incidence of falls in Parkinson's disease (PD) and to investigate predictive risk factors for fallers from baseline data. Methods: 109 subjects with idiopathic PD diagnosed according to the brain bank criteria underwent a multidisciplinary baseline assessment comprising demographic and historical data, disease specific rating scales, physiotherapy assessment, tests of visual, cardiovascular and autonomic function, and bone densitometry. Patients were then prospectively followed up for one year using weekly prepaid postcards along with telephone follow up. Results: Falls occurred in 68.3% of the subjects. Previous falls, disease duration, dementia, and loss of arm swing were independent predictors of falling. There were also significant associations between disease severity, balance impairment, depression, and falling. Conclusions: Falls are a common problem in PD and some of the major risk factors are potentially modifiable. There is a need for future studies to look at interventions to prevent falls in PD.

This study compares the sensitivity of a Patient Questionnaire versus information gathered by clinicians at a routine clinic visit in recognizing symptoms of wearing-off in early Parkinson's disease (PD). This Patient Questionnaire, containing 32 items representing a wide spectrum of motor and nonmotor wearing-off symptoms, was administered to subjects attending two PD clinics. The Patient Questionnaire results were compared to the information gathered by the clinician from the Unified Parkinson's Disease Rating Scale (UPDRS) Part IV, Question 36 and from a specific Clinical Assessment Question regarding loss of medication efficacy, wearing-off, sleepiness, dyskinesias, psychiatric complications, morning akinesia, other dopaminergic side effects, or none of the above. Examiners were blinded to study hypothesis and survey contents. Three hundred consecutive subjects with PD of <5 years duration were evaluated; the mean subject age was 72 +/- 9.6 years and 60.2% were men. Subjects reporting wearing-off were significantly younger (69.9 vs. 74.7 years) and differed regarding duration of PD symptoms (3.7 vs. 3.1 years). Wearing-off was found in 181 subjects (62.6%) by one or more of the three measures. The most sensitive tool was the Patient Questionnaire, with 165 subjects (57.1%) indicating symptoms of wearing-off. Question 36 of the UPDRS was positive in 127 subjects (43.9%), and the Clinical Assessment Question identified 85 subjects (29.4%) as experiencing wearing-off. All of these results were found to differ significantly. The mean number of wearing-off symptoms reported by the 165 subjects indicating wearing-off on the clinical survey was 6.25, with tremor being the most common motor feature and tiredness the most common nonmotor feature.

This manuscript provides a practical summary of guidelines for institution of apomorphine subcutaneous injectable therapy, including patient education, pre-treatment issues, dosage titration and side-effect care. The timing of each injection is crucial if an impending "off" period is to be averted. Patients need to be aware of symptoms of an approaching "off" period, and the injection should be administered at the onset or ideally, in anticipation of an "off" episode. Patients being considered for apomorphine treatment should undergo pre-treatment assessment and optimization of ongoing oral therapy prior to initiation. Education and counseling regarding the benefits of apomorphine can often alleviate this. In addition, and where available, it is beneficial to provide the patient and caregiver(s) with additional written information and videos provided by the manufacturer demonstrating the operation of the pump or pen injection systems. Once a patient has been assessed as being a suitable candidate for apomorphine, an apomorphine challenge is performed to determine responsiveness and guide appropriate dosing, establish an individual dose, and to observe for side effects, such as nausea, postural hypotension, excessive somnolence, or dyskinesia. Three days prior to the challenge, domperidone 20 mg tid or trimethobenzamide (Tigan) 300 mg tid is recommended. Potential side effects include yawning, dopaminergic side effects, such as dyskinesias, nausea, orthostatic hypotension, confusion, hallucinations, somnolence and rarely, hypersexuality or other behavioral disturbances, and skin nodule formation.
