Clinical research criteria for the diagnosis of progressive supranuclear palsy (Steele-Richardson-Olszewski syndrome)
To improve the specificity and sensitivity of the clinical diagnosis of progressive supranuclear palsy (PSP, Steele-Richardson-Olszewski syndrome), the National Institute of Neurological Disorders… Expand
Manganese neurotoxicity: a review of clinical features, imaging and pathology.
Manganese intoxication can result in a syndrome of parkinsonism and dystonia. If these extrapyramidal findings are present, they are likely to be irreversible and even progress after termination of… Expand
In vivo positron emission tomographic evidence for compensatory changes in presynaptic dopaminergic nerve terminals in Parkinson's disease
- C. Lee, A. Samii, +8 authors A. J. Stoessl
- Chemistry, Medicine
- Annals of neurology
- 1 April 2000
Clinical symptoms of Parkinson's disease (PD) do not manifest until dopamine (DA) neuronal loss reaches a symptomatic threshold. To explore the mechanisms of functional compensation that occur in… Expand
Assessment of Parkinson's Disease

- Clinical neuropharmacology
- 1 June 1984
The quantitative assessment of clinical deficits in Parkinson's disease has become more difficult due to such factors as the introduction of therapy that induces involuntary movements, the… Expand

The power of placebos has long been recognized for improving numerous medical conditions such as Parkinson's disease (PD). Little is known, however, about the mechanism underlying the placebo effect.… Expand
Manganism and idiopathic parkinsonism
From the comparison we have made between PD and manganism, we draw the following conclusions: 1. There are similarities between PD and manganism, notably the presence of (a) generalized bradykinesia… Expand
Criteria for diagnosing Parkinson's disease
Parkinson's disease evolves slowly, and there is current interest in exploring the earliest stages of the disorder, because of new approaches to studying pathogenesis and developing potential… Expand
Age‐dependent decline of dopamine D1 receptors in human brain: A PET study
- Y. Wang, G. Chan, +8 authors A. J. Stoessl
- Psychology, Medicine
- Synapse
- 1 September 1998
Radioligand binding studies in animals have demonstrated age‐related loss of dopamine receptors in the caudate and putamen. In humans, while age‐related declines in dopamine D2 receptors have been… Expand
Manganese intoxication in the rhesus monkey

We gave three adult rhesus monkeys seven IV injections of manganese chloride at approximate 1-week intervals. We evaluated neurologic status by serial clinical examinations and performed a levodopa… Expand
Reaction time in Parkinson's disease.

- 1 March 1981
Both reaction time and movement time tend to be prolonged in Parkinson's disease, but they are often impaired independently of each other. Prolongation of RT is relatively slight, while MT undergoes… Expand
