    A man with a large left brain infarct showed right-sided deficits, suggesting reversed hemispheric lateralization. This case challenges typical brain function localization, particularly for language and spatial processing.

    Area of Science:

    • Neuroscience
    • Neurology
    • Cognitive Science

    Background:

    • Understanding hemispheric lateralization is crucial for diagnosing and treating neurological conditions.
    • Typically, the left hemisphere is dominant for language (aphasia) and the right for visuospatial functions.

    Observation:

    • A right-handed male patient experienced a large left fronto-temporoparietal infarct.
    • Despite the extensive left hemisphere lesion, the patient did not develop aphasia.

    Findings:

    • The patient exhibited deficits in visuospatial/constructional abilities, attention, and affective functioning.
    • These observed deficits are characteristic of right-hemisphere damage.

    Implications:

    • The findings suggest a rare case of reversed hemispheric lateralization for cognitive functions.

  • This case highlights the importance of considering atypical brain organization in neurological assessments.
  • Further research into individual variations in brain lateralization is warranted.
