Summary
Mirror movements (MMs) involve difficulties in independent limb control, potentially linked to epilepsy. Studying this comorbidity may clarify the pathophysiology of MMs and epilepsy-related brain connectivity.
Area of Science:
- Neuroscience
- Neurology
- Clinical Medicine
Background:
- Mirror movements (MMs) are associated with pyramidal tract or transcallosal pathway alterations.
- Epilepsy involves seizure propagation through white matter, impacting interhemispheric communication.
Purpose of the Study:
- To investigate the potential association between epilepsy and mirror movements.
- To explore shared pathophysiological mechanisms in these conditions.
Main Methods:
- Systematic literature search of MEDLINE and Embase databases.
- Inclusion of original articles, specifically case study reports.
Main Results:
- Identified thirteen patients with co-occurring epilepsy and mirror movements from eleven case reports.
- This co-morbidity is rarely documented in existing literature.
Conclusions:
- Epilepsy and mirror movements share altered interhemispheric modulation.
- Further study of this comorbidity can elucidate mechanisms of MMs and epilepsy-related brain connectivity.

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
