    Area of Science:

    • Neuroscience
    • Neurology
    • Cognitive Science

    Background:

    • Pure alexia without hemianopia is a rare neurological condition affecting reading ability.
    • It is characterized by the inability to read despite preserved writing and spelling abilities.

    Observation:

    • A case study of a right-handed male patient presenting with pure alexia without hemianopia is detailed.
    • Neuroimaging, including CT scan and MRI, identified an intraparenchymal hematoma.

    Findings:

    • The lesion was located in the lateral temporo-occipital region of the brain.
    • This anatomical location supports the hypothesis that reading pathways are situated near the lateral temporo-occipital or inferior temporal gyrus.

    Implications:

  • This finding reinforces the understanding of the neural basis of reading.
  • It underscores the critical role of the temporo-occipital region in visual word processing and reading comprehension.
