Artery of Percheron infarct – An ophthalmologist’s perspective

Indian Journal of Ophthalmology. Case Reports
Thalamus is an important relay station in diencephalon which receives its blood supply mostly from the posterior cerebral artery. The Artery of Percheron (AOP) arises from the posterior cerebral artery and bifurcates to supply paramedian thalami.

Novel Eye Movement Disorders in Whipple’s Disease—Staircase Horizontal Saccades, Gaze-Evoked Nystagmus, and Esotropia

Frontiers in Neurology, 2017
Whipple’s disease, a rare systemic infectious disorder, is complicated by the involvement of the central nervous system in about 5% of cases. Oscillations of the eyes and the jaw, called oculo-masticatory myorhythmia, are pathognomonic of the central ...

The Disturbance of Gaze in Progressive Supranuclear Palsy (PSP): Implications for Pathogenesis

Frontiers in Neurology, 2010
Progressive supranuclear palsy (PSP) is a disease of later life that is currently regarded as a form of neurodegenerative tauopathy. Disturbance of gaze is a cardinal clinical feature of PSP that often helps clinicians to establish the diagnosis.

How to spot ocular abnormalities in progressive supranuclear palsy? A practical review

Translational Neurodegeneration, 2019
Background For parkinsonian disorders, progressive supranuclear palsy (PSP) continues to be significant for differential diagnosis. PSP presents a range of ocular abnormalities that have been suggested as optional tools for its early detection, apart ...

Spatiotemporal Tau Accumulation and its Clinical Impact on Progressive Supranuclear Palsy: Longitudinal Florzolotau (18F) Positron Emission Tomography

Movement Disorders, EarlyView.
Abstract Background Florzolotau (18F) positron emission tomography (florzolotau PET) enables high‐contrast in vivo detection of four‐repeat tau pathology in progressive supranuclear palsy (PSP), but whether longitudinal tau imaging reflects disease progression remains unclear.

Atrophy in midbrain & cerebral/cerebellar pedunculi is characteristic for progressive supranuclear palsy – A double-validation whole-brain meta-analysis

NeuroImage: Clinical, 2019
Objective: Progressive supranuclear palsy (PSP) is an atypical parkinsonian syndrome characterized by vertical gaze palsy and postural instability. Midbrain atrophy is suggested as a hallmark, but it has not been validated systematically in whole-brain ...

Agrypnia Excitata and Supranuclear Vertical Gaze Palsy Linked to Anti‐Ma Encephalitis

Movement Disorders Clinical Practice
Paraneoplastic neurological syndromes result from cancer’s immune impact on the nervous system.1 Anti-Ma-associated encephalitis causes diencephalic, brainstem, and limbic symptoms such as memory loss, narcolepsy and rapid eye movement (REM) behavior disorder (RBD), eye movement abnormalities, and parkinsonism.
