Background:
Mirror movements (MM) are involuntary movements during the voluntary movements of the contralateral homologous body parts.
Review Summary:
We report a patient with an increase in MM after suffering an epileptic seizure of his upper and lower limbs due to the right frontoparietal polymicrogyria, including the supplementary motor area as evidenced by magnetic resonance imaging. MM have been investigated using transcranial magnetic stimulation and other electrophysiological techniques in our case.
Conclusion:
This case is notable in that it is the first recorded observation of a patient manifesting mirroring after apparently suffering an epileptic seizure. In our case, we suggest that epileptic seizure increases MM by inducing cortical reorganization.
Insights
Epileptic seizures may increase mirror movements (MM), which are involuntary movements. This case suggests seizures induce cortical reorganization, potentially explaining the observed increase in MM.
Area of Science:
- Neuroscience
- Clinical Neurology
Background:
- Mirror movements (MM) are involuntary movements of contralateral homologous body parts during voluntary actions.
- Understanding the mechanisms underlying MM is crucial for diagnosing and managing neurological disorders.
Observation:
- A patient experienced an increase in mirror movements following an epileptic seizure affecting the upper and lower limbs.
- The seizure was linked to right frontoparietal polymicrogyria, involving the supplementary motor area, confirmed by MRI.
Findings:
- This is the first reported case of mirror movements manifesting after an epileptic seizure.
- Electrophysiological techniques, including transcranial magnetic stimulation, were used to investigate MM in this patient.
Implications:
- The findings suggest that epileptic seizures can exacerbate mirror movements.
- We propose that seizures may lead to increased MM by inducing cortical reorganization in the affected brain regions.
