Filter by:The purpose of the study is to assess the pharmacokinetics, pharmacodynamics, and safety of XP21279 sustained release formulation [administered with Lodosyn® (carbidopa)] and Sinemet® tablets in subjects with Parkinson's disease with Motor Fluctuations.
The aim of the study is to assess the effect of continuous levodopa infusion on autonomic nervous system in patients with Parkinson's Disease (PD), blood pressure regulation and sweating. The investigators' hypothesis is that levodopa infusion may alleviate hyperhidrosis and orthostatic hypotension.
Therapeutic management of gait disorders in very advanced Parkinson's disease (PD) patients can sometimes be disappointing, since dopaminergic drug treatments and subthalamic nucleus (STN) stimulation are more effective for limb-related Parkinsonian signs than for gait disorders. Gait disorders could be also partly related to noradrenergic system impairment, pharmacological modulation of both dopamine and noradrenaline pathways could potentially improve the symptomatology. The investigators have demonstrated using an open label study on 17 advanced PD patients that chronic, high doses of methylphenidate (MPD) improved gait, freezing of gait, motor symptoms and attention in the absence of L-Dopa and increased the intensity of response of these symptoms to L-Dopa (Devos et al., 2007). The investigators aimed to confirm their results using a randomized, double-blind, placebo-controlled, parallel-group, multicentric trial. The investigators will assess the clinical value of chronic, high doses (1 mg/kg/day) of MPD vs placebo in 88 non demented PD patients suffering from severe gait disorders with freezing despite their use of optimal dopaminergic doses and eventually STN stimulation parameters. Efficacy will be assessed directly and on video in the absence of L-Dopa and again after acute administration of the drug, both before and after a 3-month course of MPD, using Stand Walk Sit test (primary criteria), the "Freezing Of Gait trajectory", RGSE scale, the UPDRS scores, the dyskinesia rating scale, Achiron scales and using auto-questionnaires of Giladi, ABC scale and PDQ 39. Attention will be assessed using reactions times. Drowsiness will be assessed using Epworth and Parkinson's disease Sleep Scales. Apathy and depression will be monitored with Lille Apathy Rating Scale, MADRS, BPRS, MINI and psychiatric interview. Cardiologic and general tolerance will be also monitored. This study could lead to propose methylphenidate with a good efficacy/ risk balance in advanced PD patients suffering from severe gait disorders with freezing of gait, drowsiness and attention deficit.
The investigators tested whether prospective memory is impaired in individuals with Parkinson's Disease compared to controls using reliable and validated experimental measures. Also, the investigators assessed the impact of Parkinson's medication on prospective memory performance in PD to better estimate prospective memory function in PD patients' everyday (chronically treated) life.
Nearly all Parkinson's disease (PD) patients eventually develop abnormal and unwanted movements (dyskinesias; LID) caused by the gold standard treatment, Levodopa. The severity of these movements can range from subtle to extremely debilitating and may or may not interfere with normal activities such as putting on a coat or brushing ones teeth. The purpose of this study is to demonstrate the validity and reliability of objectively measuring dyskinesia with a forceplate.
The purpose of this study is to find out if a medication that increases levels of a brain chemical called acetylcholine will improve balance and reduce falls in patients with parkinson's disease who have the problem of very poor balance and are frequently falling or nearly falling on a daily basis. Donepezil, a drug approved for the treatment of Alzheimer's dementia, will reduce falls in subjects with Parkinson's disease and balance impairment.
The purpose of this study is to determine if Amitiza (lubiprostone), a drug proven to be safe and effective for chronic constipation, will also improve constipation symptoms in Parkinson's Disease patients. We will also evaluate the impact of the drug on changes in bowel movement consistency, quality of life and motor symptoms.
There is convincing evidence from numerous studies using both psychophysical and electrophysiological approaches that olfaction is markedly reduced in Parkinson´s disease (PD). Data on the prevalence of olfactory dysfunction in PD however, range from 45% and 49% in the pioneering studies of Ansari & Johnson, and Ward, respectively, up to 74% in the work of Hawkes et al., or as high as 90% in a study published by Doty et al. Quality of life, safety, and interpersonal relations, as well as food behavior/nutritional intake are severely altered in a large proportion of patients with olfactory loss. Thus, the same can be assumed in patients with Parkinson's disease. If it was possible to improve olfactory function this would appear as a significant effect in patients with Parkinson's disease. Provided the study would reveal an improvement of olfactory function following therapy with rasagiline, this would have tremendous worldwide impact on the use of this drug. Considering the frequency of PD a very large number of patients would benefit from these findings, especially in terms of quality of life.
The purpose of this research study is to investigate the cognitive (thinking, memory, knowledge, intelligence) side effects of two medications commonly used to treat overactive bladder (OAB) symptoms in veteran patients with Parkinson's disease (PD) seen at the Philadelphia PADRECC.
Parkinson's disease (PD) causes motor and non-motor impairments that affect the quality of life of the subjects. The purpose was to assess the effects of treadmill walking training with additional body load on the quality of life and motor symptoms of the subjects with PD. Methods: Nine subjects with PD, Hoehn and Yahr stages 2 through 3, not demented and with capability to ambulate independently voluntarily participate in this study. The training program was divided into three phases (A1-B-A2): treadmill training with additional body load (A1), control condition (conventional physical therapy group) (B) and treadmill training with load again (A2). Each phase lasted six weeks. The quality of life and motor symptoms were assessed by PDQ-39 and UPDRS, respectively. Both evaluations and training were performed during on-phase of the medication cycle.
