| History |
The patient is a 60 year old woman who was given a diagnosis of Progressive supranuclear palsy six months before she was referred by the Movement Disorders Clinic for evaluation of difficulty reading. Family History: Negative for neurodegenerative disease. Neuro-ophthalmological examination: Supranuclear vertical gaze palsy (saccades and pursuit) Convergence absent Prominent stare Slow hypometric horizontal saccades Slow horizontal pursuit Deviation of the eyes up under closed lids (Bell's phenomenon) Vertical oculocephalic reflexes normal Positive Glabella tap Diagnosis: Progressive supranuclear palsy (PSP) Global supranuclear vertical gaze palsy Paresis of downgaze prevented the patient from reading in her usual position with her book or paper on her knee. She was helped by prescribing separate reading glasses corrected for reading with the eyes in primary position. Previously, she had had moon bifocals which are particularly unsatisfactory for older people as convergence fails. (View ID 932-3 and ID 939-3). |
| Anatomy |
Supranuclear paralysis of vertical gaze localizes to the mesencephalic reticular formation and the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF). The riMLF is a wing-shaped structure that lies dorsomedial to the red nucleus and rostral to the interstitial nucleus of Cajal. The riMLF contains burst neurons for vertical and torsional saccades. The riMLF projects predominantly to the ipsilateral oculomotor (third nerve) and trochlear (fourth nerve) nuclei. |
| Pathology |
In an autopsy case of PSP, a pale locus ceruleus and substantia nigra are two typical gross features on inspection of the brainstem. Neuronal loss, granulovacuolar degeneration and fibrillary gliosis are present in areas of neuronal change. There is widespread neuronal and glial tau accumulation in the cortex, basal ganglia, in periaqueductal gray matter, subthalamic nucleus, red nucleus, substantia nigra, pedunculopontine nucleus, superior colliculus, and in the dentate nucleus of the cerebellum. Microscopically, globose neurofibrillary tangles are observed. The neuronal cytoplasmic inclusions are strongly immunoreactive for tau. Tufted astrocytes are a specific finding in PSP. They are often binucleate and have long tau reactive processes. The intracellular aggregation of tau in PSP may be sufficient to cause nerve cell degeneration. |
| Disease/Diagnosis |
Progressive Supranuclear Palsy - tauopathy |
| Clinical |
This patient with supranuclear vertical gaze palsy has the following: A supranuclear vertical gaze palsy (saccades and pursuit) Convergence absent A prominent stare Slow hypometric horizontal saccades Slow horizontal pursuit Deviation of the eyes up under closed lids (Bell's phenomenon) Vertical oculocephalic reflexes normal Positive Glabella tap |
| Presenting Symptom |
Difficulty reading |
| Ocular Movements |
Global Supranuclear Vertical Gaze Palsy; Convergence absent; Prominent Stare; Slow Hypometric Horizontal Saccades; Slow Horizontal Pursuit; Vertical Oculocephalic Reflex Normal; Positive Glabella Tap |
| Neuroimaging |
No neuroimaging studies are available in this patient. |
| Treatment |
There is no cure for PSP. Once the disease has begun, its course is relentlessly progressive. |
| Etiology |
PSP is a "tauopathy". Studies suggest that it is a recessive disorder in linkage disequilibrium with the tau gene. Rare familial forms of PSP exist including an autosomal dominant transmission with incomplete penetrance. The relationship to the tau gene further suggests a relationship to frontotemporal dementia/Pick's Disease (FTDP) and some families carrying the FTDP-17 mutation (chromosome 17) have affected members with PSP-like phenotypes. |
