Glabellar and palmomental reflexes in parkinsonian disorders

Neurology, 2004
The authors examined the glabellar reflex and the palmomental reflex in 100 subjects, including patients with Parkinson disease (n = 41), patients with progressive supranuclear palsy (n = 12), patients with multiple system atrophy (n = 7), and healthy, age-matched, controls (n = 40).

Brain perfusion differences in Parkinsonian disorders

Movement Disorders, 2011
AbstractWe aimed to objectively examine the brain perfusion differences between PD, Parkinson variant of multiple system atrophy, and progressive supranuclear palsy. 99mTc ethylcysteinate dimer single‐photon emission CT (SPECT) was performed in 28 patients with PD, 12 with Parkinson variant of multiple system atrophy, 19 with progressive supranuclear ...

The Role of Tau Imaging in Parkinsonian Disorders

Current Neurology and Neuroscience Reports, 2018
Differential diagnosis of atypical Parkinson syndromes (APS) is difficult as clinical presentations may vary and as there is a strong overlap between disease entities. Aggregations of misfolded and hyperphosphorylated tau proteins are the common denominator of many of these diseases.Several tau targeting positron emission tomography (PET) tracers have ...

The auditory startle reaction in parkinsonian disorders

Movement Disorders, 2001
The auditory startle reaction to an unexpected loud stimulus is regarded as a brainstem reflex originating in the nucleus reticularis pontis caudalis and being distributed up the brainstem and down the spinal cord along slowly conducting pathways. Auditory startle responses (ASR) have been reported absent or reduced in progressive supranuclear palsy ...

Tracking the neurodegeneration of parkinsonian disorders – a pilot study

Neuroradiology, 2007
The purpose of the study was to explore the possibilities of using diffusion tensor imaging (DTI) and tractography (DTT) for the differential diagnosis and monitoring of disease progression in idiopathic Parkinson's disease (IPD), compared with the atypical parkinsonian disorders multiple system atrophy (MSA) and progressive supranuclear palsy (PSP).

Cerebrospinal Fluid Levels of Neurogranin in Parkinsonian Disorders

Movement Disorders, 2019
AbstractBackgroundCSF concentration of neurogranin has been suggested as a biomarker for synapse dysfunction.ObjectivesTo investigate CSF neurogranin in parkinsonian disorders compared to controls and Alzheimer's disease and the possible correlations between neurogranin and cognitive and motor impairment.MethodsWe included 157 patients with PD, 29 with

Transcranial sonography in parkinsonian disorders

2021
Parkinson's disease is extremely difficult to diagnose, given that no test provides conclusive evidence for the disease. Many patients in the early stages of the disease have very few symptoms or experience symptoms that overlap with other conditions that resemble Parkinson's disease, known as parkinsonian disorders.

Recent advances in atypical parkinsonian disorders

Current Opinion in Neurology, 1999
Recent advances in epidemiologic, diagnostic, pathologic, and management aspects of atypical parkinsonian disorders are reviewed and placed in perspective. The implications of considering progressive supranuclear palsy and corticobasal degeneration as tauopathies, and multiple system atrophy and dementia with Lewy bodies as alpha-synucleopathies are ...

Disorders of Intention in Parkinsonian Syndromes

2003
In recent years, the symptom of akinesia in parkinsonism has provided a valuable window into the physiological substrate of voluntary movement in man, particularly the role of the basal ganglia and the influence of dopamine. In a similar way, the study of individual nonmotor symptoms in parkinsonism can provide insights into the subsystems underlying ...
