Increased Latency of Visual Evoked Potentials in Healthy Women during Menstruation

چکیده
PURPOSE To evaluate the latency of visual evoked potentials (VEPs) in healthy women during and after menstruation. METHODS Pattern and flash VEPs were performed in 15 healthy women aged 18 to 25 years on the maximum bleeding day (luteal phase) and 7 days after the menstrual cycle (follicular phase). RESULTS Mean latency was 119.6 msec on the maximum bleeding day and 100.8 msec one week after menstruation on pattern VEP (P < 0.001). Corresponding values for flash VEP were 124.5 msec and 112.7 msec, respectively (P < 0.001). CONCLUSION Prolonged VEP latency on the maximum bleeding day indicates that high progesterone levels may have an inhibitory effect on optic nerve conduction velocity.

Increased Latency of Visual Evoked Potentials in Healthy Women during Menstruation
We congratulate Dr. Azarmina and colleagues on their study investigating the latency of visual evoked potentials (VEPs) among healthy females during and after menstruation.1 The authors found significantly increased latencies in pattern and flash VEP in their subjects. Their findings are particularly remarkable since the mean latency of the P100 wave was increased by approximately 20 ms (mean i...
متن کاملThe Effect of Oral Verapamil on the Visual Evoked Potentials in Definite Multiple Sclerosis Patients
Introduction: Ionic channel rearrangements through the demyelinated axons or supporting media play significant role in remission of the neurological deficit in MS patients. In this study the effects of Verapamil as a calcium channel blocker on central conduction have been investigated through the evaluation of changes in P100 latency of the visual evoked potential. Method: This randomized doubl...

Background : To determine the effect of binocular summation on the time domain transient VEP wave's components. Methods : The monocular and binocular transient visual evoked potentials of 21 normally vision volunteers 18 to 24 years (mean ± SD, 20.7 ± 1.9) during a reversing checkerboard stimulus with spatiotemporal frequency of 2.18-4 cpd-Hz were recorded. The amplitude and latency of N75,...
متن کاملComparison of visual evoked potential changes in patients with alzheimer, vascular dementia and minimal cognitive Impairment with healthy people: a case-control study
Background: Alzheimer dementia as the most common cause of dementia is a chronic, progressive, irreversible and incurable disease. The second most common cause of dementia after Alzheimer is vascular dementia. One of the systems involved in dementia is the visuospatial system and visual evoked potential (VEP) can be one of the diagnostic methods for this disease. Therefore, the present study ai...
متن کاملP300 Component Modulation During a Go/Nogo Task in Healthy Children
ABSTRACT Introduction: Several differences in the P300 component are observed when responses must be executed or inhibited in the Go/Nogo task. However, few studies were established by using well-controlled task with respect to the preparatory processing and stimulus probability. In the present study, we examined the peak amplitude and latency of Go-P300 (P300 evoked by visual Go stimuli) and N...
