It can be caused by a number of different reasons, some benign, unknown reasons, but also are commonly associated with lesions, tumors, and encephalopathies. [3] ...
Polymicrogyria (PMG) is a condition that affects the development of the human brain by multiple small gyri creating excessive folding of the brain leading to an abnormally thick cortex.
Panayiotopoulos syndrome (named after C. P. Panayiotopoulos) is a common idiopathic childhood-related seizure disorder that occurs exclusively in otherwise normal children (idiopathic epilepsy) and manifests mainly with autonomic epileptic seizures and autonomic status epilepticus. [1]
Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production.
Electrode locations of International 10-20 system for encephalography recording. The 10–20 system or International 10–20 system is an internationally recognized method to describe and apply the location of scalp electrodes in the context of an EEG exam, polysomnograph sleep study, or voluntary lab research.
A drawing of the human brain showing the thalamus and cortex relative to other structures. The spike-and-wave pattern seen during an absence seizure is the result of a bilateral synchronous firing of neurons ranging from the neocortex (part of the cerebral cortex) to the thalamus, along the thalamocortical network.

Bilateral frontoparietal polymicrogyria is a genetic disorder with autosomal recessive inheritance that causes a cortical malformation. Our brain has folds in the cortex to increase surface area called gyri and patients with polymicrogyria have an increase number of folds and smaller folds than usual. [1]
Lennox–Gastaut syndrome (LGS) is a complex, rare, and severe childhood-onset epilepsy syndrome. It is characterized by multiple and concurrent seizure types including tonic seizure, cognitive dysfunction, and slow spike waves on electroencephalogram (EEG), which are very abnormal. [1]
