Summary

Body asymmetry is a useful indicator for diagnosing localisation-related epilepsy. This finding can also help lateralise seizure origins in partial onset seizures, aiding diagnostic management strategies.

Area of Science:

  • Neurology
  • Clinical Neuroscience

Background:

  • Differentiating localisation-related epilepsy from generalised epilepsy is crucial for effective diagnostic and management strategies.
  • Body asymmetry (BA) is frequently observed in patients with localisation-related epilepsy syndromes.

Purpose of the Study:

  • To investigate the relationship between clinically detectable body asymmetry and the electro-anatomic characteristics of epilepsy.
  • To determine if body asymmetry can aid in differentiating epilepsy types and lateralising seizure origins.

Main Methods:

  • A retrospective study of 337 patients with seizure disorders was conducted.
  • Body asymmetry was documented, and 56 patients were excluded due to various non-epileptic conditions.
  • The association between body asymmetry and epilepsy type (localisation-related vs. generalised) was analyzed.

Main Results:

  • Body asymmetry was present in 88 of 282 eligible patients (31.2%).
  • Patients with localisation-related epilepsy showed significantly higher rates of body asymmetry (41.5%) compared to those with generalised epilepsy (18.75%).
  • In partial onset seizures, body asymmetry lateralisation was concordant with seizure origin in 75.9% of cases.

Conclusions:

  • Clinically detectable body asymmetry is a valuable clue for diagnosing localisation-related epilepsy.
  • Body asymmetry may assist in lateralising the seizure origin in partial onset seizures, improving diagnostic accuracy.
