BACKGROUND: 'Wearing off' refers to the phenomenology of movement disorders in Parkinson's disease (PD) that appears early and is much commoner than generally believed. It may be present in the form of either motor symptoms or non-motor symptoms. AIM: To investigate the utility of wearing-off questionnaire (WOQ-19, Italian version) in the outpatient clinical practice to assess the suitability of different combinations of treatment, in various stages of PD. METHODS: 73 consecutive patients (58% male and 42% female) suffering from PD were recruited through the Santorso Hospital and San Martino Hospital from September 2012 to March 2014...

Levo-dopa (L-DOPA) has shown significant and long-lasting efficacy in the treatment of motor features characteristic of Parkinson's disease (PD). However, the effects tend to wear off at a time typically when side-effects, such as L-DOPA induced dyskinesias (LIDs), start to emerge and for which the treatment options are very limited. In recent years, we have reported on the neuroprotective and neurorestorative properties of the compounds cystamine/cysteamine in ameliorating several aspects of PD. Building on these observations, we set out to further evaluate the benefits of cysteamine on LIDs...

INTRODUCTION: Falls are a disabling feature of Parkinson's disease (PD). In this prospective study we investigated: (1) in which motor state patients with PD fallmost often; and (2) whether freezing of gait (FOG) and dyskinesias contribute to falls. METHODS: Patients with PD who had fallen at least once in the previous year and had wearing-off were recruited. During six months, patients complete a standardized fall report. We analyzed data regarding fall circumstances and motor state at the time of each first 10 falls...

PURPOSE: Istradefylline is useful in treating the wearing-off state in Parkinson's disease (PD). We investigated the effectiveness of istradefylline (ISD) in improving arousal, sleep, and gait deficits in patients with PD. METHODS: We examined 14 patients with PD treated with ISD. We assessed the patients using the Unified Parkinson's Disease Rating Scale, Parkinson's Disease Questionnaire, Timed Up-and-Go test (TUG), Freezing of Gait Questionnaire (FOG-Q), Epworth Sleepiness Scale (ESS), and Parkinson's Disease Sleep Scale (PDSS) before and 1 month after ISD use...

Parkinson's disease (PD) is a progressive movement disorder caused by the death of dopamine-producing cells in the midbrain. There is a need for frequent symptom assessment, since the treatment needs to be individualized as the disease progresses. The aim of this paper was to verify and further investigate the clinimetric properties of an entropy-based method for measuring PD-related upper limb temporal irregularities during spiral drawing tasks. More specifically, properties of a temporal irregularity score (TIS) for patients at different stages of PD, and medication time points were investigated...

OBJECTIVES: The adenosine A2A antagonist istradefylline has been used to treat Parkinson disease (PD) with symptoms of wearing-off since 2013 in Japan. Previous randomized controlled trials of istradefylline compared with placebo included PD patients experiencing an average daily OFF time of more than 2 hours. The purpose of this study is to assess the efficacy of 20 mg/d istradefylline in PD subjects experiencing an average daily OFF time of 3 hours or less. METHODS: Fifteen patients were enrolled into this retrospective study...

Wearing-off refers to the predictable worsening of motor and sometimes non-motor symptoms of Parkinson's disease occurring at the end of levodopa dose that improves with the next drug dose. Here, we investigated the efficacy of rasagiline on executive functions at the end of levodopa dose in patients displaying symptoms of wearing-off. Rasagiline was well-tolerated and produced a significant improvement at the Frontal Assessment Battery, together with improvement of motor symptoms at the end of levodopa dose...

BACKGROUND: Our group earlier developed a small monitoring device, which uses accelerometer measurements to accurately detect motor fluctuations in patients with Parkinson's (On and Off state) based on an algorithm that characterizes gait through the frequency content of strides. To further validate the algorithm, we studied the correlation of its outputs with the motor section of the Unified Parkinson's Disease Rating Scale part-III (UPDRS-III). METHOD: Seventy-five patients suffering from Parkinson's disease were asked to walk both in the Off and the On state while wearing the inertial sensor on the waist...

Levodopa-induced dyskinesia (LID) is commonly seen in Parkinson's disease patients treated with levodopa. This side effect is usually encountered after long duration of treatment, but occasionally, this may be seen even after few days or months of treatment. LID is broadly classified as peak-dose dyskinesia, wearing-off or off-period dyskinesia, and diphasic dyskinesia. Pathogenesis of LID is complex, and different neurotransmitters such as dopamine, glutamine, adenosine, and gamma-aminobutyric acid play important role altering the normal physiology of direct and indirect pathway of cortico-basal ganglia-thalamic loop responsible for fine motor control...

Since the effect of a percutaneous absorption-type dopamine agonist (DA) preparation, rotigotine patch, stably persists by once-a-day application, this dosage form is appropriate for Parkinson's disease patients showing levodopa induced wearing off phenomenon. On the other hand, skin disorders, mainly application site reaction, are characteristic problems associated with use of the patch. In this study, to clarify the influence of a topical agent used to prevent or treat rotigotine patch-induced skin disorder on continuation of the patch application, patients who started rotigotine patch application at our hospital were retrospectively surveyed...

BACKGROUND: Istradefylline, a selective adenosine A2A receptor antagonist, has been reported to improve daily "off time" and motor symptoms in patients with Parkinson's disease (PD). However, the effect of istradefylline on sleep problems has not been thoroughly investigated. METHODS: We evaluated the effect of istradefylline on daytime sleepiness, sleep disturbances, and motor symptoms in 22 PD patients who were affected by the wearing off phenomenon in an open-label, 3-month study...

BACKGROUND: Exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist, has neuroprotective effects in preclinical models of Parkinson's disease. We investigated whether these effects would be apparent in a clinical trial. METHODS: In this single-centre, randomised, double-blind, placebo-controlled trial, patients with moderate Parkinson's disease were randomly assigned (1:1) to receive subcutaneous injections of exenatide 2 mg or placebo once weekly for 48 weeks in addition to their regular medication, followed by a 12-week washout period...

BACKGROUND: Mood disorders are very frequent in Parkinson's Disease (PD), and their effective treatment is still a major unresolved issue: growing evidence suggests that glutamatergic system dysfunction is directly involved. Safinamide is a drug with an innovative mechanism of action, dopaminergic and non-dopaminergic, that includes the reversible inhibition of the monoamine oxidase-B (MAO-B) enzyme and the modulation of excessive glutamate release through the use- and state-dependent blockade of the sodium channels...

Levodopa is considered to be the most effective symptomatic drug for Parkinson's disease (PD). As the disease progresses, however, the patients are likely to experience a reduced response to levodopa and develop motor fluctuations (i.e., end-of-dose wearing off and unpredictable "on-off"). Protein-rich diets and elevated plasma concentrations of large neutral amino acids have been proved to impair the therapeutic effect of levodopa by reducing its absorption and influx into the brain. On the other hand, the protein-restricted diets including low-protein diet (LPD), protein-redistribution diet (PRD) and PRD with use of low-protein products can all improve the efficacy of levodopa in patients with motor fluctuations...

BACKGROUND: Levodopa bioavailability is enhanced by adding entacapone. However, the optimal dose of levodopa while transitioning to levodopa/carbidopa/entacapone (LCE) in Parkinson's disease (PD) during the wearing-off period is unclear. AIMS: The relative therapeutic efficacy and safety of different doses of levodopa were assessed when transitioning to the LCE combination for optimizing combined levodopa therapy. MATERIALS AND METHODS: A randomized, multicenter, double-arm, open-label study was conducted in Korea...
