Event-related brain potentials to high incentive stimuli in abstinent alcoholics.

We have previously found that the P3 component of the event-related potential (ERP) is reduced in alcoholics in visual target-selection paradigms. P3 voltage depends on the "subjective significance" of the stimulus (e.g.

The N2 component of the event-related brain potential in abstinent alcoholics.

The latencies of the N2 component of the ERP and reaction time were manipulated in abstinent alcoholics and controls. The experimental design consisted of visual stimuli that differed in difficulty of discrimination. N2 latencies were found to be significantly delayed in alcoholics compared to controls, particularly for the easy discrimination.

Event-related brain potentials in boys at risk for alcoholism.

Recent neurophysiological findings have demonstrated that abstinent chronic alcoholics manifest deficits in event-related brain potentials. To explore possible biological antecedents of alcoholism the present study examined boys at high risk for alcoholism. Event-related brain potentials were recorded from biological sons of alcoholic fathers and matched control boys.

Oral cytologic patterns and nutritional status: some relationships in alcoholic subjects.

Exfoliative cytologic preparations from the cheeks of 790 alcoholic patients were evaluated for relationships between microscopic features and selected indicators of nutritional status. Significant associations were observed between the cell/nucleus ratio, degree of cornification, relative concentrations of leukocytes and microorganisms, and poor dietary patterns, as well as body weight statua and serum albumin and blood hemoglobin levels. Microscopic examination, as an adjunct to gross inspection of the mouth, may be of value in the clinical assessment of nutriture.
