This study reports two cases of progressive aphasia with focal left temporal lobe abnormalities. Unlike typical cases, the onset occurred later in life, at ages 68 and 69.

Area of Science:

  • Neurology
  • Neuroimaging
  • Linguistics

Background:

  • Progressive aphasia (PA) is a neurodegenerative disorder affecting language abilities.
  • Typical PA often presents with presenile onset and specific patterns of brain atrophy.
  • Magnetic resonance imaging (MRI) is crucial for identifying structural brain changes.

Observation:

  • Two patients presented with progressive aphasia without accompanying dementia.
  • Both patients exhibited focal abnormalities in the left temporal lobe on MRI scans.
  • The age of onset for these patients was 68 and 69 years, which is later than typical.

Findings:

  • The MRI findings revealed focal left temporal lobe abnormalities in both patients.
  • The late-onset presentation (68 and 69 years) distinguishes these cases from many previously documented PA instances.

  • These observations suggest a potential variant of progressive aphasia with later onset and specific imaging correlates.

    • Implications:

    • This case study broadens the understanding of the clinical and radiological spectrum of progressive aphasia.
    • It highlights the importance of considering late-onset presentations in the diagnosis of PA.
    • Further research is warranted to explore the etiology and long-term prognosis of such cases.
