Acute stroke can cause cerebral ptosis and gaze deviation. This may result from damage to brain connections, suggesting a bihemispheric representation rather than a single affected area.

Area of Science:

  • Neurology
  • Neuroscience
  • Stroke Medicine

Background:

  • Cerebral ptosis and gaze deviation are potential neurological deficits following acute stroke.
  • The precise neuroanatomical correlates of these symptoms are not fully elucidated.

Purpose of the Study:

  • To investigate the neuroanatomical basis of cerebral ptosis and gaze deviation in patients after acute stroke.
  • To explore the potential for bihemispheric involvement in these post-stroke symptoms.

Main Methods:

  • Retrospective analysis of nine patients presenting with cerebral ptosis and gaze deviation post-stroke.
  • Review of neuroimaging (brain scans) to identify lesion locations.

Main Results:

  • All nine patients exhibited extensive lesions in the fronto-parieto-temporal regions.

  • Five patients had lesions localized to the left cerebral hemisphere.

    • Conclusions:

    • Cerebral ptosis and gaze deviation following stroke may arise from damage to interhemispheric connections.
    • These symptoms suggest a bihemispheric representation, implicating widespread brain network disruption rather than focal damage.
