Brain somatic mosaicism is increasingly recognized in focal epilepsies, revealing distinct molecular pathway dysfunctions. New discoveries are improving diagnostic yields, potentially reclassifying common epilepsies as genetic disorders.
Area of Science:
- Neuroscience
- Genetics
- Epilepsy Research
Background:
- Brain somatic mosaicism is a key factor in focal epilepsies.
- The discovery of somatic variants is rapidly expanding, implicating diverse pathologies.
- This phenomenon highlights dysfunction in specific molecular pathways across different epilepsy types.
Conclusions:
- Brain somatic mosaicism is a significant contributor to focal epilepsies.
- Advancements in genetic analysis are improving the diagnosis of epilepsy.
- Somatic mosaicism may necessitate a paradigm shift in understanding and treating common focal epilepsies as genetic conditions.

Seizures: Classification
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:
