Metabolic Causes of Epilepsy - An Introduction
Epilepsy is a chronic neurological disorder characterized by repeated aberrant electrical activity in the brain and recurrent spontaneous seizures.

Quantitative EEG - An Introduction
Quantitative Electroencephalography (qEEG) is the digital analysis of the raw EEG data with the application of mathematical and analytical techniques to characterize the EEG signal.
Basics of EEG
20 minutes of artifact-free recording of epileptiform activity that consists of synchronized depolarization and repolarization of thalamic and cortical neurons. 20-electrode placement system along with bipolar and referential montages allows comparison of epileptiform activity on both sides of the brain as well as localization of seizure. Many provocative techniques such as hyperventilation, intermittent photic stimulation, and sleep are used to produce epileptiform waves.
Differentiating Frontal Lobe Epilepsy from Psychogenic Nonepileptic Seizures
There are three major categories of seizures: 1) Epileptic seizures (ES), 2) Psychogenic Nonepileptic Seizures (PNES), 3) Physiologic nonepileptic events (NEEs). PNES/NESS are can be difficult to distinguish from ES.
Sudden Unexpected Death in Epilepsy (SUDEP)
Sudden, unexpected, non-traumatic, non-drowning, witnessed or unwitnessed death, in any individual who has history of epilepsy, excludes documented status epilepticus and post-mortem examination does not reveal any cause (anatomical or toxicological) of death.
Seizures prophylaxis in Chronic Subdural Hematoma
Anti-seizures medications (ASM) are sometimes used prophylactically in CSDH, but no current guidelines are available for ASM therapy
