“…A consistent finding in CAEP studies of children with epilepsy is that P3 latencies are prolonged but with normal amplitudes [88,90,91,[94][95][96][97][98][99][100]. This pattern holds across studies of children with idiopathic generalized epilepsy [94,96,99], idiopathic partial epilepsies including Benign Rolandic epilepsy [95,96,[99][100][101], occipital paroxysmal discharges [95,[97][98][99], and symptomatic partial epilepsies [95][96][97]99,100].…”

“…Oral administration of diazepam has been associated with prolonged P3 latencies, with no affect on amplitude [117]. P3 latencies were also found to increase in children receiving phenobarbital [102,115], carbamazepine [100,101,116], and with high-dose phenytoin [116]. Furthermore, P3 latencies decreased following discontinuation of phenobarbitol, while P3 amplitudes increased following discontinuation of carbamazepine, phenobarbitol, and valproate [115].…”

“…Studies of antiepileptic medication effects in humans and animals have reported prolonged CAEP latencies [100][101][102][111][112][113][114][115][116]. For example, carbamazepine was found to increase P1 latencies to visual stimuli in children [114].…”

“…Absent MMN responses have also been reported in children with partial epilepsies. Prolonged CAEP latencies have been associated with the presence of spikes [90] or increased spike frequency [95,100]. However, prolonged latencies have also been observed in the absence of spikes [87], suggesting that the underlying epileptic brain regions may be responsible.…”

Children with epilepsy are at increased risk for language impairments. Recent studies have suggested that abnormal cortical processing of complex sounds, including speech, may be a contributing factor. Cortical auditory evoked potentials provide an objective, non-invasive method for assessing auditory function in children. We begin with an overview of the cortical auditory system, cortical auditory evoked potentials, and childhood epilepsies. This overview provides a framework for reviewing recent studies using auditory evoked potentials to evaluate sound processing in children with epilepsy. Clinical implications, methodological considerations, and directions for future research are discussed.

Biological, phenomenological and cognitive similarities are known to exist between schizophrenia and schizotypal personality disorder (SPD). This study examined whether, and to what extent, abnormalities in event-related potentials (ERPs) already extensively reported in schizophrenia can also be observed in persons psychometrically identified with SPD. Event-related potentials were examined in nine SPD subjects and nine controls recruited from among 1693 college students, using the Schizotypal Personality Questionnaire (SPQ) and the Structured Clinical Interview for DSM-III-R (SCID I and II). Event-related potentials were recorded during an auditory oddball task. Smaller P300 amplitude and prolonged P300 latency were found in SPD subjects as compared with controls. Our findings indicate that such individuals do have deficits in information processing similar to that found in schizophrenia. We can conclude that P300 abnormalities may not be specific for SPD but that abnormalities shown in SPD are possibly a vulnerability marker for developing schizophrenia.

Purpose: Serious concerns about the effect of mobile phone radiation on cognition are growing. This study aimed to assess the possible effect of mobile phone radiation in persons with epilepsy and in normal subjects. Methods: The amplitude and reaction time of auditory event–related potentials (P300) and occipital alpha frequency were compared before and after exposure with a 30-minute call in 30 persons with epilepsy and in 30 control subjects. Alpha power was monitored before, during, and after exposure to mobile phone radiation. Moreover, correlations with clinical aspects were analyzed. Results: Increased reaction time and decreased P300 amplitude were more evident in persons with epilepsy. A significant decrease in alpha power was noted in control subjects and persons with epilepsy and was associated with an increased bilateral alpha frequency. In persons with epilepsy, such changes significantly correlated with the time since the last seizure and with the therapy regimen. Conclusions: Thirty-minute exposure to mobile phone radiation has a significant effect on the electrophysiological correlates of cognition, especially in persons with epilepsy.
