Is epilepsy more heritable from maternal side?
Epilepsy is a neurological disorder characterized by hypersynchronous discharge of neurons .i.e abnormal electrical activity in the brain. Epileptic seizures caused primarily due to i) inhibition of inhibitory neurotransmitter systems such GABA neurotransmitters or ii) Enhancement of excitatory neurotransmitter systems such as nAchR. These conditions arise due to head injury, trauma and genetic factors. But there is no evidence as of now regarding Mitochondrial DNA taking part in inhibitory and excitatory systems. so, epileptic seizures are not specific in inheriting from any side (Maternal or paternal side) as far as pathophysiology of epilepsy is concerned.
