“…Gil et al 17 tried to correlate P300 latency increase with alterations in the neuropsychological tests in MS patients, and they did not find amplitude and latency differences in P200, N200 and P300 potentials among the subgroups classified by the McAlpine criteria. In the present study, it was possible to correlate MMN to alterations in a neuropsychological test.…”

Mi smatch Negativity is a functional index of the supratemporal auditory cortex. Aim: The aim of the present study on Mismatch Negativity (MMN) in multiple sclerosis (MS) patients was to evaluate if the MMN can be correlated with cognitive deficits assessed by the Paced Auditory Addition Task -PASAT. Method: a clinical study in forty females and 20 males separated in two groups: control individuals and those with a definite diagnosis of MS underwent a duration and frequncy MMN. The MMN latencies and negative amplitudes obtained from the MS group were compared to the ones from the control group. The scores from the Paced Auditory Addition Task were correlated either with the presence or the absence of MMN. Results: MMN was found in 60% of the individuals with multiple sclerosis within the auditory stimulation protocol with varied durations, and in 45 % within the auditory stimulation protocol with frequency variations. There were no statistically significant differences in latencies and amplitudes when compared to controls. We found a statistically significant correlation for the lack of MMN wave together with cognitive disorder asserted by the PASAT. Conclusions: The MMN correlated to the cognitive deficit assessed by the PASAT.

“…Delayed latency and decreased amplitude of the main ERPs components, particularly of the P3 to oddball paradigm, representing the discrimination of stimuli differing in some physical dimension and whose latency reflects processing speed [36], have been reported in MS [38,42]. Delayed P3 is associated with higher EDSS scores [22,67], disease duration [25], low performance on attention and memory tasks and total MRI lesion burden [30,49,63]. Previous neuroimaging and neuropsychological studies pointed out the need for early detection of cognitive impairment in MS [1,46], possibly at the subclinical level.…”

Background: Dysfunction of higher cognitive abilities occurs in 40-60 % of people with multiple sclerosis (MS), as detected with neuropsychological testing, with predominant involvement of executive functions and processing speed. Event-related potentials to the Stroop are a bioelectrical correlate of executive function. We tested whether event-related potentials to the executive Stroop test may reflect executive dysfunction in MS.

“…P300 potentials have been used as a reliable neurophysiological marker for various neurological conditions. Multiple sclerosis, stroke, Alzheimer's disease and myotonic dystrophy are illnesses that have been analyzed employing this test [9][10][11][12] . Visioli-Melo and Rotta 13 , analyzing epileptic brazilian children, did not found differences in P300 when compared with non epileptic children.…”

-Objective: To examine auditory cognitive evoked potentials (P300 potentials) and neuropsychological dysfunction in patients with Duchenne muscular dystrophy (DMD). Method: P300 potentials and neuropsychological test results were obtained from 16 healthy control boys and 20 DMD patients. Full Intelligence Quotients (IQ) were estimated for patients and control group. Mean age was 9.5 years in the DMD patient group, and 10 years in the control group (p>0.05). Results: The mean IQ values were 64.35 in the DMD patients and 82.68 in the control group (p=0.01). Mean P300 values were 347.6 in the DMD group and 337.4 in the control group (p=0.14). There was no significant correlation between parameters in each group. Conclusion: DMD patients showed a poor performance as evaluated by P300 potential compared to the control group, although the difference was not statistically significant. Systematic alterations in neuropsychological test results were found, the differences paralleling those detected in IQ.
