This study describes a patient with intermittent alexia and dysgraphia, likely caused by migraines. Blood flow scans suggest a vascular origin for these neurological disturbances.

Area of Science:

  • Neurology
  • Neuroscience
  • Vascular Neurology

Background:

  • Migraine is a common neurological disorder.
  • Alexia and dysgraphia are complex neurological deficits affecting reading and writing.
  • Understanding the underlying mechanisms of transient neurological symptoms is crucial.

Observation:

  • A case study of intermittent alexia and varying degrees of dysgraphia is presented.
  • The patient experienced episodes of inability to read, with concurrent writing difficulties.
  • Neurological assessments revealed impaired right-left orientation, visual short-term memory deficits, and finger agnosia.

Findings:

  • The intermittent alexia and dysgraphia were suspected to be of migrainous origin.
  • Single-photon emission computed tomography (SPECT) scans showed altered blood flow during alexic episodes.

  • These findings support a vascular etiology for the observed transient neurological symptoms.

    • Implications:

    • This case highlights a potential link between migraine and transient alexia/dysgraphia.
    • Vascular mechanisms may underlie certain types of reading and writing impairments.
    • Further research into migraine-related neurological deficits is warranted.
