The heterogeneity of Parkinson’s disease
AbstractThe heterogeneity of Parkinson’s disease (PD), i.e. the various clinical phenotypes, pathological findings, genetic predispositions and probably also the various implicated pathophysiological pathways pose a major challenge for future research projects and therapeutic trail design.

Parkinson's disease dementia: a neural networks perspective. [PDF]
In the long-term, with progression of the illness, Parkinson's disease dementia affects up to 90% of patients with Parkinson's disease. With increasing life expectancy in western countries, Parkinson's disease dementia is set to become even more ...

Noradrenaline and Parkinson's Disease [PDF]
Parkinson's disease (PD) is characterized by the degeneration of dopamine (DA) neurons in the substantia nigra pars compacta, and motor symptoms including bradykinesia, rigidity, and tremor at rest. These symptoms are exhibited when striatal dopamine concentration has decreased by around 70%.

The competitive NMDA antagonist CPP protects substantia nigra neurons from MPTP-induced degeneration in primates [PDF]
Degeneration of nigrostriatal dopaminergic neurons is the primary histopathological feature of Parkinson's disease. The neurotoxin MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) induces a neurological syndrome in man and non-human primates very ...

Methamphetamine and Parkinson's Disease [PDF]
Parkinson's disease (PD) is a neurodegenerative disorder predominantly affecting the elderly. The aetiology of the disease is not known, but age and environmental factors play an important role. Although more than a dozen gene mutations associated with familial forms of Parkinson's disease have been described, fewer than 10% of all cases can be ...

Abnormal temporal coupling of tactile perception and motor action in Parkinson's disease [PDF]
Evidence shows altered somatosensory temporal discrimination threshold (STDT) in Parkinson's disease in comparison to normal subjects. In healthy subjects, movement execution modulates STDT values through mechanisms of sensory gating.

Parkinson's disease: autoimmunity and neuroinflammation [PDF]
Parkinson's disease is a neurodegenerative disease that causes the death of dopaminergic neurons in the substantia nigra. The resulting dopamine deficiency in the basal ganglia leads to a movement disorder that is characterized by classical parkinsonian ...

Primary skin fibroblasts as a model of Parkinson's disease [PDF]
Parkinson's disease is the second most frequent neurodegenerative disorder. While most cases occur sporadic mutations in a growing number of genes including Parkin (PARK2) and PINK1 (PARK6) have been associated with the disease.

Imaging in Parkinson's Disease [PDF]
Parkinson's disease (PD) is a chronic neurodegenerative disease characterized by the loss of nigrostriatal dopaminergic neurons and aggregation of misfolded α-synuclein in Lewy bodies. The underlying mechanisms of neurodegeneration in PD are still unknown, and there are no disease-modifying treatments to slow the neurodegenerative processes.

Characterization of vitamin D supplementation and clinical outcomes in a large cohort of early Parkinson's disease. [PDF]
BackgroundVitamin D (VitD) deficiency is common in Parkinson's disease (PD) and has been raised as a possible PD risk factor. In the past decade, VitD supplementation for potential prevention of age related conditions has become more common.
