Visual evoked potentials in alcoholics.

I Ahmed, K S Hines

Clinical EEG (Electroencephalography)

|January 1, 1983

Summary

This summary is machine-generated.

Early alcohol intoxication can cause abnormal visual evoked potentials (VEPs). Nutritional treatment improved VEPs in some patients, suggesting potential for recovery.

Background:

Alcohol consumption is a widespread issue with significant health implications.
Alcohol intoxication can affect various physiological systems, including the visual pathway.
Visual evoked potentials (VEPs) are a non-invasive tool to assess the integrity of the visual pathway.

Purpose of the Study:

To investigate the impact of early-phase alcohol intoxication on visual evoked potentials (VEPs).
To evaluate the potential for recovery of VEPs following nutritional intervention in patients with alcohol-induced abnormalities.

Main Methods:

Visual evoked potentials (VEPs) were recorded in 19 patients during the early stages of alcohol intoxication.
Abnormal VEP responses were identified and monitored.

Follow-up VEP testing was conducted at 3-4 week intervals after treatment with vitamins and balanced diets.

Main Results:

Out of 38 recorded VEP responses, 13% (5 responses) were abnormal in the intoxicated patients.
Three out of the five patients with abnormal VEPs showed normalization of major positive peaks after nutritional treatment.
VEP abnormalities were observed in the early phase of alcohol intoxication.

Conclusions:

Early alcohol intoxication can lead to detectable abnormalities in visual evoked potentials.
Nutritional interventions, including vitamins and balanced diets, may contribute to the recovery of visual pathway function in some individuals affected by alcohol.
VEPs can serve as a biomarker for alcohol's neurotoxic effects and the efficacy of treatment.
