Although children with benign infantile epilepsy typically have a normal EEG between seizures, some infants have been found to have a characteristic abnormal EEG during sleep. Called benign infantile focal epilepsy with midline spikes and waves during sleep, these infants have few seizures and there may often be a family history. [4]
It is an abnormal interictal pattern, consisting of high amplitude and irregular waves and spikes in a background of chaotic and disorganized activity seen on electroencephalogram (EEG), and frequently encountered in infants diagnosed with infantile spasms, although it can be found in other conditions such as tuberous sclerosis.
Infants present with a characteristic seizure type called infantile spasms (repetitive spells of body crunching, each spell lasting less than 2-3 seconds, but which occur in brief clusters). The EEG is always severely abnormal and often shows a pattern called hypsarrhythmia.
A neonatal seizure is a seizure in a baby younger than age 4-weeks that is identifiable by an electrical recording of the brain. [1] It is an occurrence of abnormal, paroxysmal, and persistent ictal rhythm with an amplitude of 2 microvolts in the electroencephalogram,. [2]
EEG abnormalities do not appear to determine clinical manifestations, duration, severity, and frequency of seizures or prognosis. [ citation needed ] There are now significant reports of ictal EEGs in 20 cases, which objectively document the seizures of Panayiotopoulos syndrome and their variable localisation at onset. [ 18 ]

Even though an abnormal EEG reading is common in LKS patients, a relationship has not been identified between EEG abnormalities and the presence and intensity of language problems. In many cases however, abnormalities in the EEG test has preceded language deterioration and improvement in the EEG tracing has preceded language improvement (this ...
Such spasms are found in association with characteristic abnormal EEG pattern findings (hypsarrhythmia), and cognitive delay or deterioration. [2] [4] The peak age of onset is 4-6 months of age, with 90% of cases presenting during the first year of life. The spasms are usually resistant to conventional antiepileptics. They may persist beyond ...
