Active clinical trials for "Parkinson Disease"

Researchers are to determine if turning on an additional unilateral DBS (deep brain stimulation) electrode with stimulation to the globus pallidus externa (GPe) region of the brain will improve insomnia (sleep).

This is a randomized clinical trial in an online format, which will only include people with PD randomly divided into two groups: Group 1 - Social Telerehabilitation with Dance and Music Group 2 - Social Telerehabilitation with Multimodal Therapeutic Exercise and Music

The purpose of this study is to assess how alternating-frequency Deep Brain Stimulation (DBS) works to improve postural instability and gait, while also treating other motor symptoms of Parkinson Disease (PD).

Parkinson's disease (PD) is one of the most common neurodegenerative diseases characterized by the progressive loss of dopaminergic (DA) neurons in the substantia nigra compacta (SNc) and aggregation of Lewy bodies in neurons. Although aging, oxidative damage and neuroinflammation have been recognized to play crucial roles in the pathogenesis of PD, the precise etiology remains obscure. Emerging evidence suggests PD is a systemic metabolic disease, and metabolic abnormality correlates with functional alternations in PD

Individuals with Parkinson's disease demonstrate impaired motor learning, including a slower acquisition rate and poor retention, which may result from deficits in cognitive function, especially executive function. Considering the reduced motor learning ability in this patient group, exercises should be designed with a focus on strengthening sensory inputs and basic functional training. Therefore, the investigators established this program according to previous experience published study [NCT04063605]. Therefore, the feasibility of this rehabilitation protocol, which combines motor learning and clinical pilates principles and is adapted to the needs of individuals with Parkinson's disease, will be examined.

This study investigates whether vestibular (inner ear) dysfunction is a cause for poor balance in Parkinson Disease (PD), and whether inner ear stimulation with a small device may improve balance. This study will involve clinical testing, brain imaging, and an interventional treatment device for symptoms.

Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. Besides causing symptoms that impair movement, PD also causes non-motor symptoms, such as problems thinking and orthostatic hypotension (OH), i.e., low blood pressure (BP) when standing. About one-third of people with PD have OH, which can cause sudden, temporary symptoms while upright, including lightheadedness, dizziness, and fainting. People with PD and OH can also experience problems thinking that happen only while upright and not while sitting - this can occur without other symptoms, such as feeling dizzy or faint. However, the level of low BP that can affect thinking remains unknown, and no guidelines exist for treating OH when it happens without symptoms. This is significant because OH could be a treatable risk factor for thinking problems in PD, but OH is often not treated if people do not report obvious symptoms. This project's goal is to determine how BP affects brain function in PD. The proposed experiments will measure BP and brain blood flow continuously in real-time using innovative wearable technology. Persons with PD with OH and without OH will undergo repeated cognitive tests while supine (lying down) and while upright. I will study the associations between BP, thinking abilities, and brain blood flow, and will compare groups with and without OH. These findings could be important because if a certain level of BP correlates with thinking abilities, then treating OH in PD may prevent thinking problems, which would improve health-related quality of life and reduce disability and healthcare costs.

Physiotherapy and targeted rehabilitation are routinely performed in order to influence disorders of posture, gait and stability in Parkinson´s disease (PD), but their effects have been controversial (Keus et al. 2014; Walton wt al. 2014). Recently, several studies suggested that cognitive training can improve gait in patients with PD (Peterson et al. 2016, Heremans et al. 2013), similar to the effects seen in the elderly (Yogev-Seligmann et al. 2008; Amboni et al. 2013). Specific training programs including dual tasking with automatic verbal series, counting etc. have led to increased walking speed and improved stepping cadence, length, and duration in patients with dementia (Schwenk et al. 2010). However, since in advanced PD patients dual-task gait training has to be supervised by therapists, it is not a suitable type of therapy to be performed at home. Therefore, this study aims to verify and extend the encouraging results of the single study which showed a positive effect of cognitive function training on gait in PD (Milman et al. 2014) by exploring this effect in advanced PD patients, by assessing the effect on gait using more targeted clinical and instrumental evaluation, and by comparing two modes of therapy delivery, group and computer-based.

The Swedish BioFINDER 2 study is a new study that will launch in 2017 and extends the previous cohorts of BioFINDER 1 study (www.biofinder.se). BioFINDER 1 is used e.g. to characterize the role of beta-amyloid pathology in early diagnosis of Alzheimer's disease (AD) using amyloid-PET (18F-Flutemetamol) and Aβ analysis in cerebrospinal fluid samples. The BioFINDER 1 study has resulted in more than 40 publications during the last three years, many in high impact journals, and some the of the results have already had important implications for the diagnostic work-up patients with AD in the clinical routine practice. The original BioFINDER 1 cohort started to include participants in 2008. Since then there has been a rapid development of biochemical and neuroimaging technologies which enable novel ways to the study biological processes involved in Alzheimer's disease in living people. There has also been a growing interest in the earliest stages of AD and other neurodegenerative diseases. With the advent of new tau-PET tracers there is now an opportunity to elucidate the role of tau pathology in the pathogenesis of AD and other tauopathies. The Swedish BioFINDER 2 study has been designed to complement the BioFINDER 1 study and to e.g. address issues regarding the role of tau pathology in different dementias and in preclinical stages of different dementia diseases. Further, the clinical assessments and MRI methods have been further optimized compared to BioFINDER 1.
