Objective:

To characterize cortical atrophy patterns and CSF biomarkers of Alzheimer’s disease in patients with late-onset temporal lobe epilepsy (LO-TLE) and assess their significance.

Key Findings:
  • CSF biomarkers in LO-TLE patients were normal and significantly different from those in MCI-AD patients, indicating a potential distinction in neurodegenerative processes.
  • No significant differences in cortico-subcortical atrophy between LO-TLE patients and healthy controls, suggesting preserved brain structure.
  • MCI patients exhibited widespread cortico-subcortical injuries, unlike LO-TLE patients, highlighting the differences in neurodegenerative features.
Interpretation:

LO-TLE patients with short disease duration and normal CSF amyloid-β and tau levels show cortical and subcortical patterns similar to healthy controls, contrasting with MCI patients, which may have implications for diagnosis and treatment.

Limitations:
  • Small sample size of LO-TLE patients (20 participants) may limit the robustness of the findings.
  • Short disease duration may limit generalizability of findings and the understanding of long-term outcomes.
Conclusion:

LO-TLE may not share the same neurodegenerative features as Alzheimer’s disease, as indicated by normal CSF biomarkers and similar brain atrophy patterns to healthy controls, emphasizing the need for careful clinical differentiation.
