Vertical oculomotor apraxia and memory loss

R P Mills, P D Swanson

    Annals of Neurology
    |August 1, 1978
    PubMed
    Summary

    A rare case of vertical oculomotor apraxia, memory loss, and inertia occurred in a woman using oral contraceptives. This eye movement disorder, linked to medial thalamic damage, suggests acute infarction.

    Area of Science:

    • Neurology
    • Neuro-ophthalmology

    Background:

    • Oral contraceptives are associated with various neurological risks, including thromboembolic events.
    • Oculomotor apraxia is a rare disorder affecting voluntary eye movements.

    Observation:

    • A 34-year-old woman using oral contraceptives presented with vertical oculomotor apraxia, severe memory loss, and hypokinetic inertia.
    • Electronystagmography confirmed true apraxia with random involuntary vertical saccades, while other eye movements remained intact.

    Findings:

    • The patient exhibited paralysis of voluntary vertical saccades but normal pursuit, reflex, and horizontal saccadic movements.
    • Neuroimaging revealed abnormalities in the medial thalami, consistent with similar reported cases.
    • The clinical presentation suggested acute infarction in the paramedian thalamosubthalamic artery territory, possibly embolic.

    Implications:

    • This case highlights a potential link between oral contraceptive use and specific neurological deficits.
    • Medial thalamic infarction can manifest as vertical oculomotor apraxia and cognitive impairment.
    • Understanding these associations is crucial for clinical diagnosis and patient management.
