This is a prospective observational study investigating the utility of 7 Tesla MRI to quantify nigrosome1 signal in a cohort of individuals with recent onset Parkinson's disease and in at-risk cohorts at a premotor state of Parkinson's disease.

By creating a neurogenebank from Parkinson's disease patients' blood donations we will ultimately be able to define genes for Parkinson's disease and other neurological conditions.
Prospective observational study of Parkinson's disease with repeat clinical assessment and biobanking of blood samples.
The purpose of this study is to determine if the 9zest app for Parkinson's disease is feasible, safe, and efficacious when used independently by individuals with Parkinson's disease.
The aim of this research is to discover genes which modify risk for Parkinson's disease. The study includes 800 patients with Parkinson's disease, and their estimated 1,222 available sibli...
Multi-center, retrospective observational cohort study in 4 tertiary referral centers in Cairo over the period from 2004 to 2016. Study population. including all patients with idiopathic ...
Visual hallucinations (VHs) are common in Parkinson's disease (PD), with prevalence ranging from 27-50% in cross-sectional cohorts of patients with well-established disease. However, minor hallucinati...
Wearable-sensors provide accurate, continuous objective measurements, quantifying the variable motor states of patients with Parkinson's disease (PD) in real time.
Exercise is increasingly recognized as an important element in the treatment of Parkinson's disease but what is exercise targeting? What accounts for the benefits observed in Parkinson's disease? Is e...
Although, current medications for Parkinson's disease can control and relief symptoms of the disease efficiently, they are unable to either prevent progression of the disease or maintain their control...
Neurological disorders are now the leading source of disability globally, and the fastest growing neurological disorder in the world is Parkinson disease. From 1990 to 2015, the number of people with ...
Proteins associated with sporadic or familial cases of PARKINSON DISEASE.
A condition caused by the neurotoxin MPTP which causes selective destruction of nigrostriatal dopaminergic neurons. Clinical features include irreversible parkinsonian signs including rigidity and bradykinesia (PARKINSON DISEASE, SECONDARY). MPTP toxicity is also used as an animal model for the study of PARKINSON DISEASE. (Adams et al., Principles of Neurology, 6th ed, p1072; Neurology 1986 Feb;36(2):250-8)
A group of disorders which feature impaired motor control characterized by bradykinesia, MUSCLE RIGIDITY; TREMOR; and postural instability. Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA.
Parkinsonism following encephalitis, historically seen as a sequella of encephalitis lethargica (Von Economo Encephalitis). The early age of onset, the rapid progression of symptoms followed by stabilization, and the presence of a variety of other neurological disorders (e.g., sociopathic behavior; TICS; MUSCLE SPASMS; oculogyric crises; hyperphagia; and bizarre movements) distinguish this condition from primary PARKINSON DISEASE. Pathologic features include neuronal loss and gliosis concentrated in the MESENCEPHALON; SUBTHALAMUS; and HYPOTHALAMUS. (From Adams et al., Principles of Neurology, 6th ed, p754)
Conditions which feature clinical manifestations resembling primary Parkinson disease that are caused by a known or suspected condition. Examples include parkinsonism caused by vascular injury, drugs, trauma, toxin exposure, neoplasms, infections and degenerative or hereditary conditions. Clinical features may include bradykinesia, rigidity, parkinsonian gait, and masked facies. In general, tremor is less prominent in secondary parkinsonism than in the primary form. (From Joynt, Clinical Neurology, 1998, Ch38, pp39-42)
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Parkinson's is a progressive neurological condition, affecting one person in every 500, 95% of which are over 40. It is caused by degeneration of more than 70% of the substantia nigra, which depletes the dopamine (the neurotransmitter involved in pro...
