Filter by:Balance and gait impairment increases the risk of falls and contributes to a reduced quality of life and shorter survival in Parkinson disease (PD) and atypical Parkinsonism patients. In preliminary case studies, electrical epidural spinal cord stimulation (SCS) has been shown to significantly improve gait, postural instability, rigidity, and tremor. Controlled studies for optimizing which stimulation settings produce the best clinical response for mobility and gait, and achieving these results chronically are all significant unmet needs. Using quantitative laboratory and mobile technologies to test a range of stimulation settings, this research study aims to determine which SCS parameters or combination of parameters is best suited to effectively alleviate disabling symptoms experienced by each patient.
This study evaluates the effect of transcranial direct current stimulation (tDCS) on non-motor symptoms of Parkinson's disease, including depression and cognitive symptoms. Participants are randomized to receive active or sham tDCS for 30 minutes over 10 treatment sessions.
In certain neurosurgical procedures, the use of a stereotaxic frame is required. It is then possible to set a precise target (depending of the type of the surgery) to be reached by the surgeon. The fixation of the stereotactic frame on the awake patient's head is done under local anesthesia by screwing the frame directly into the skull. This procedure is reported as "painful" to "extremely painful" by patients. The objective of this study is to determine whether the hypnosis is effective in decreasing the pain perceived by the patient during the disposal of the stereotactic frame.
Ten sessions of repetitive transcranial magnetic stimulation yield ability to upregulate the function of primary motor cortex and prefrontal cortex that play key roles in motor and frontal memory processing.
In the VFS paradigm the stimulation frequency was set to alternate between high and low frequencies, where the frequency of stimulation or frequency combinations can be changed instantaneously according to damage of the moment rhythms. Variable frequency stimulation is a novel dynamic therapy which breaks through the existing single high-frequency stimulation paradigms. It is the world's first VFS therapy for the brain.
Parkinson's Disease (PD) is defined by characteristic motor symptoms including slow movements, small movements, difficulty with movement initiation and disruptions in timing. Besides gross motor symptoms, fine motor impairments in PD cause difficulties with everyday tasks such as writing, self-care, and fine object manipulation. These activity limitations can lead to disability, social isolation, and a reduced quality of life. In a series of breakthrough studies Michael Thaut and colleagues developed Neurologic Music Therapy (NMT) and found it can address many gross motor impairments and improve gait and balance. Other music therapies such as Music-supported Therapy (MST) have proven motor benefits in stroke patients through movement exercises with musical instruments. However, the pathological basal ganglia (BG) in PD brains leads to a reduced supply of those internally generated movements. In contrast, externally cued movements (eg. via a beat or a rhythm) during NMT sessions are instantaneously entrained to the period of a rhythmic stimulus possibly without involvement of the BG. The underlying idea is that rhythm is the essential component relating music specifically to motor behavior. The mechanism of action is called "rhythmic entrainment" where one system's motion or signal frequency entrains the frequency of another system. The effect of NMT on fine motor function has not been investigated yet. Music activities are important in the lives of many older adults. Notably, the use of music has been associated with increased well-being for older adults, as it fosters social connection and mood regulation. Furthermore, many musical activities have limited physical demands, making them attainable for individuals who are living with mobility impairments or other physical restrictions. Based on the literature and the investigators preliminary studies, the investigators propose to test the efficacy of Neurologic Music Therapy in comparison to Music Supported Therapy and Occupational Therapy (OT) as standard of care on adults in the Parkinson's spectrum. The investigators have defined a working plan using different musical instruments and growing tempo to specifically improve fine motor movements.
The objective of this study is to evaluate the performance of novel DBS programming methods compared to traditional programming methods.
The objective of the ADDIA clinical Proof-of-Performance study is to validate the performance of ADDIA' blood biomarkers for diagnosis of Alzheimer's disease (AD). ADDIA clinical study is a multi-centre, non-interventional, prospective, proof-of-performance study with only one visit. About 800 well-characterized subjects will be recruited into 3 groups in 2:1:1 ratio, namely patients with Alzheimer's disease (AD), patients with non-AD neurodegenerative disease (NAD) and 200 control subjects (healthy as compared to their age). - 400 patients with Alzheimer's disease (AD): 200 patients with mild AD, 200 patients with moderate-to-severe AD, - 200 patients with non-Alzheimer's neurodegenerative diseases (NAD), - 200 controls (healthy as compared to their age).
Depression is considered to be the most common neuropsychiatric disturbance of PD. In this study, investigators will summarize the treatment profile of PD depression to see if PD depression is properly treated according to guideline.
Parkinson's disease (PD) has been classically regarded as a "movement disorder", so earlier work has focused on treating motor symptoms only. As PD patients now have longer life expectancy, the relatively slowly progressing cognitive deficits (compared to their motor deficits) have become one of the major challenges. Approximately 80% of PD patients eventually become demented. Therefore cognitive dysfunction is one of the most significant factors affecting the quality of life of patients with PD. While dementia in Parkinson's disease is routinely treated by cholinesterase inhibitors (e.g., donepezil and rivastigmine), their efficacy on mild cognitive impairment found in non-demented PD is questionable. Alternative approaches have been proposed including transcranial direct current stimulation (tDCS) but no consensus has been reached. This can be attributed mainly to: (1) imprecise knowledge of the underlying functional circuitry mediating this disease manifestation and (2) inter-individual variability. Here, the investigators will utilize a novel personalized network analysis approach to elucidate on the underlying mechanisms of the effect of tDCS on cognitive dysfunction in non-demented PD patients. It has been well documented that the caudate nucleus plays an important role in cognitive dysfunction found in PD. In the investigators' preliminary resting-state functional magnetic resonance imaging (fMRI) study, they have shown that the connectivity of the right caudate nucleus is correlated to cognitive status of PD patients measured by the Montreal Cognitive Assessment (MoCA). The investigators hypothesize that tDCS on the left and/or right dorsolateral prefrontal cortex may restore the functional connectivity of the right caudate nucleus which may in turn improve patients' cognitive performance.
