Progressive supranuclear palsy (PSP) is rare neurodegenerative disorder characterized by deposition of fibrillar aggregates of 4R tau-protein in neurons and glial cells. This disorder is underdiagnosed due to the overlap of the clinical syndrome with other related conditions. The clinical manifestations include cognitive impairment associated with behavioral changes, akinetic rigid syndrome, and prominent oculomotor dysfunction. We present the F-FDG and F-THK5351 PET images of a 71-year-old man diagnosed of probable PSP. This image highlights the hopeful results of the new tau-PET ligands radiotracers, because it allows to assess the distribution of tau-protein over time, closely associated with neurodegeneration in PSP.

Radiological biomarkers have been reported for multiple system atrophy and progressive supranuclear palsy, but serum/plasma biomarkers for each disorder have not been established. In this context, we ...
Statins were proposed to be neuroprotective; however, the effects are unknown in progressive supranuclear palsy (PSP), a pure tauopathy.
Microstructural white matter integrity captured by diffusion-tensor imaging (DTI) is significantly more affected in progressive supranuclear palsy-Richardson's syndrome (PSP-RS) compared to PSP-parkin...
Progressive Supranuclear Palsy (PSP) patients present language disturbances in tasks like naming, repetition, reading, word comprehension and semantic association compared to Parkinson's disease (PD) ...

The purpose of this study is to evaluate the long-term safety and tolerability of multiple intravenous (IV) infusions of BMS-986168 in patients with Progressive Supranuclear Palsy (PSP). T...
This study is designed to learn more about overall tau burden in the brain of patients with Progressive Supranuclear Palsy (PSP).
Progressive supranuclear palsy (PSP) is the most common atypical parkinsonian movement disorder. This study will determine the role of specific genetic, occupational and environmental com...
The purpose of this study is to determine the efficacy and safety of intravenously administered BMS-986168 in participants with Progressive Supranuclear Palsy.
The clinical syndrome of PSP responds poorly to all available forms of therapy used in Parkinson's Disease (PD). Currently, no effective treatment exists. Coenzyme Q10 in high doses has b...
Neurodegenerative disorders involving deposition of abnormal tau protein isoforms (TAU PROTEINS) in neurons and glial cells in the brain. Pathological aggregations of tau proteins are associated with mutation of the tau gene on chromosome 17 in patients with ALZHEIMER DISEASE; DEMENTIA; PARKINSONIAN DISORDERS; progressive supranuclear palsy (SUPRANUCLEAR PALSY, PROGRESSIVE); and corticobasal degeneration.
A degenerative disease of the central nervous system characterized by balance difficulties; OCULAR MOTILITY DISORDERS (supranuclear ophthalmoplegia); DYSARTHRIA; swallowing difficulties; and axial DYSTONIA. Onset is usually in the fifth decade and disease progression occurs over several years. Pathologic findings include neurofibrillary degeneration and neuronal loss in the dorsal MESENCEPHALON; SUBTHALAMIC NUCLEUS; RED NUCLEUS; pallidum; dentate nucleus; and vestibular nuclei.

Diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. Clinical subtypes are distinguished by the major site of degeneration. In AMYOTROPHIC LATERAL SCLEROSIS there is involvement of upper, lower, and brainstem motor neurons. In progressive muscular atrophy and related syndromes (see MUSCULAR ATROPHY, SPINAL) the motor neurons in the spinal cord are primarily affected. With progressive bulbar palsy (BULBAR PALSY, PROGRESSIVE), the initial degeneration occurs in the brainstem. In primary lateral sclerosis, the cortical neurons are affected in isolation.

A motor neuron disease marked by progressive weakness of the muscles innervated by cranial nerves of the lower brain stem. Clinical manifestations include dysarthria, dysphagia, facial weakness, tongue weakness, and fasciculations of the tongue and facial muscles. The adult form of the disease is marked initially by bulbar weakness which progresses to involve motor neurons throughout the neuroaxis. Eventually this condition may become indistinguishable from AMYOTROPHIC LATERAL SCLEROSIS. Fazio-Londe syndrome is an inherited form of this illness which occurs in children and young adults.

Systematic identification of a population's needs or the assessment of individuals to determine the proper level of services needed.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
