Committee of the European Academy of Neurology in Brussels, Belgien. He is also a member of the high level advisory board for the European Ministry for Research and Development " Scientific Panel for Health (SPH) ". He has received many prestigious awards during his career, including the " carrier award for basal ganglia disorders " On the International Conference: Clinical Update Sleep 2016, w...
BACKGROUND Mutations in the PTEN-induced kinase (PINK1) gene located within the PARK6 locus on chromosome 1p35-p36 have recently been identified in patients with recessive early-onset Parkinson disease. OBJECTIVE To assess the prevalence of PINK1 mutations within a series of early- and late-onset Parkinson disease patients living in North America. DESIGN All coding exons of the PINK1 gene w...
Mutations in alpha-synuclein gene cause familial form of Parkinson disease, and deposition of wild-type alpha-synuclein as Lewy bodies occurs as a hallmark lesion of sporadic Parkinson disease and dementia with Lewy bodies, implicating alpha-synuclein in the pathogenesis of Parkinson disease and related neurodegenerative diseases. Dopamine neurons in substantia nigra are the major site of neuro...
Artificial neural network(ANN) with tansig, logsig and purelin transfer function, support vector machines(SVM), linear and quadratic classifiers are used in this work for the detection of Parkinson disease using voice features. In the Parkinson disease, voice of a person changes because of presence of tremor in the voicebox muscles. Total 195 phonations were used for the analysis from twenty th...
Parkinson disease is a neurological disorder. In this disease control over body muscles get disturbed. In almost 90% of the cases, people suffering from Parkinson disease (PD) have speech disorders. The goal of the paper is to differentiate healthy and PD affected persons using voice analysis. There are no well-developed lab techniques available for Parkinson detection. Parkinson detection usin...
In this Commentary, I describe the events that led from an NINDS-sponsored Workshop on Parkinson Disease Research in 1995, where I was asked to speak about the genetics of Parkinson disease, to the identification a mere two years later of a mutation in alpha-synuclein as the cause of autosomal dominant Parkinson disease in the Contursi kindred. I review the steps we took to first map and then f...
UNLABELLED Loss of nigrostriatal neurons leading to dopamine depletion in the dorsal striatum is the pathologic hallmark of Parkinson disease contributing to the primary motor symptoms of the disease. However, Parkinson pathology is more widespread in the brain, affecting also other dopaminergic pathways and neurotransmitter systems, but these changes are less well characterized. This study aim...
BACKGROUND AND PURPOSE The burden of amyloid β is greater in patients with dementia with Lewy bodies than in those with Parkinson disease dementia, and an increased amyloid β load is closely related to a higher incidence of cerebral microbleeds. Here, we investigated the prevalence and topography of cerebral microbleeds in patients with dementia with Lewy bodies and those with Parkinson disease...
Strength training has, in recent years, been shown to be beneficial for people with Parkinson disease and multiple sclerosis. Consensus regarding its utility for these disorders nevertheless remains contentious among healthcare professionals. Greater clarity is required, especially in regards to the type and magnitude of effects as well as the response differences to strength training between i...
BACKGROUND AND PURPOSE Both diffusion tensor imaging and the apparent transverse relaxation rate have shown promise in differentiating Parkinson disease from atypical parkinsonism (particularly multiple system atrophy and progressive supranuclear palsy). The objective of the study was to assess the ability of DTI, the apparent transverse relaxation rate, and their combination for differentiatin...
