“…Clinically, there may be eyelid flutter, vertical oscillations of the eyelids and eyeballs, and jerks involving the face and head (Noachtar et al, 1999). It most often is seen in tense, anxious individuals and can occasionally occur in alcohol withdrawal (Fisch et al, 1989).…”

The EEG is the most common neurodiagnostic test performed to evaluate patients with suspected seizures. The majority of EEGs are requested in patients because of suspected seizures or for seizure management. It is unlikely that the patient's usual spell will be recorded during a routine EEG. Therefore, several activation techniques have been used in clinical EEG to help increase the occurrence of interictal epileptiform abnormalities, which are highly correlated with the diagnosis of a seizure disorder. EEG laboratories have long employed these techniques, which include hyperventilation, intermittent photic stimulation, sleep, and sleep deprivation. However, despite being utilized in routine clinical EEGs for decades, a number of differing views on the usefulness and indications for these procedures exist. This review will evaluate these procedures and review their history, technique, effectiveness, controversies, and unanswered questions.

“…To address the influence of benzodiazepines on identification of photomyoclonic or photoconvulsive responses in patients undergoing withdrawal, Fisch et al (1986) performed EEGs on 49 patients within 48 h of their last drink. All demonstrated some features of withdrawal, but none had received benzodiazepines or other sedatives at the time of EEG recording.…”

Seizures, epilepsy, and alcohol are complexly interrelated. Although it is commonly perceived that patients with epilepsy experience problems with seizure control if they use alcohol, this is not confirmed by the few experimental studies that have tested the hypothesis. The last 30 years have emphasized the role of withdrawal from alcohol as a mechanism of seizure production. However, this is but one of many potential mechanisms by which seizures and epilepsy may be related to alcohol use and abuse. The rare but clear situations in which alcohol can act as a convulsant drug need further study, and mechanisms by which the long-term neurotoxic effects of alcohol lead to chronic epilepsy also need further elucidation.

“…Since generalized seizures may occur during alcohol withdrawal, the expectation could be that the PPR as a generalized discharge may be found in the state. However, Fisch et al 62 never found the PPR in his group of 49 patients in withdrawal.…”

The Photoparoxysmal Response: The Probable Cause of Attacks during Video Games

Photic stimulation is part of a typical EEG in most countries, especially to check on the photoparoxysmal response (PPR). Interest in this response was enhanced in 1997 when hundreds of Japanese children had attacks while viewing a TV cartoon called "Pokemon." The overall prevalence of the PPR among patients requiring an EEG is approximately 0.8%, but 1.7% in children and 8.87% in patients with epilepsy, more often in Caucasians and females. Autosomal dominant inheritance is indicated, and this response is seen especially at the wavelength of 700 nm or at the flicker frequency of 15-18 Hz. The PPR extending beyond the stimulus carries no increased risk of seizures. Prognosis is generally good, especially after 20 years of age. Attention to PPR has been increased with the advent of video games, and the evoked seizures from these games are likely a manifestation of photosensitive epilepsy. Drug therapy has emphasized valproic acid, but Levetiracetam has also been successful in eliminating the PPR.
