EEG Spectral Changes in Treatment-Naive, Actively Drinking Alcoholics

EEG spectral changes in treatment-naive, actively drinking alcoholics.

BACKGROUND The current study examines the EEG spectra of actively drinking, treatment-naive alcoholics (TxNAs). METHODS EEGs were gathered on 51 TxNAs and age- and sex-matched controls during closed-eyes conditions. Participants were excluded for lifetime diagnoses of psychiatric or substance abuse disorders. Power for the theta to high beta bands was examined across midline electrodes. RES...

Mismatch negativity: no difference between treatment-naive alcoholics and controls.

BACKGROUND Several studies have examined the mismatch negativity (MMN) evoked potential as a measure of a brain inhibitory deficit in alcoholics or those at risk for alcoholism. This study examined MMN in actively drinking treatment-naive alcohol-dependent individuals. This study examined the association of MMN with risk factors for alcoholism, postalcohol withdrawal hyperexcitability, and alco...

Theta power in the EEG of alcoholics.

BACKGROUND In this study, the magnitude and spatial distribution of theta power in the resting EEG were examined to explore the changes in the neurophysiological status of the alcoholic brain. Some state- and trait-related issues of theta power increases in the EEG of alcoholics were also examined. METHODS Absolute theta (3-7 Hz) power in eyes-closed EEGs of 307 alcohol-dependent subjects and...

Phases in the drinking history of alcoholics.

Loss of Control Drinking in Alcoholics

W this landmark article was published in 1973, the domi­ nant model of alcoholism considered it a dispositional dis­ ease, the cardinal symptom of which is inevitable loss of control whenever alcohol is consumed. The reasons for this loss of con­ trol over drinking were generally assumed to be physiological, an automatic and irreversible reaction to the chemical ethanol (pure alcohol). A few co...
