Alcohol and the Developing Brain: Neuroanatomical Studies
One of the distinguishing features of prenatal alcohol exposure is impaired cognitive and behavioral function resulting from damage to the central nervous system. Information available from the small number of autopsied cases in humans indicates that...
Alcoholism and Human Electrophysiology
Electroencephalography (EEG), the recording of electrical signals from the brain, provides a noninvasive measure of brain function as it is happening. Research using EEG, as well as event-related potentials (ERPs) and event-related oscillations (EROs),...
Alcoholism and the Brain: An Overview
Alcoholism can affect the brain and behavior in a variety of ways, and multiple factors can influence these effects. A person's susceptibility to alcoholism-related brain damage may be associated with his or her age, gender, drinking history, and nutrition,...
Alcohol, Neural Stem Cells, and Adult Neurogenesis
Recent research demonstrates that neural stem cells divide throughout life and give rise to new neurons, a process known as neurogenesis. This article addresses two principal questions concerning alcohol and adult neurogenesis: To what extent are neurogenesis...
Hepatic Encephalopathy - a Serious Complication of Alcoholic Liver Disease
Alcohols harmful effects on liver cells not only interfere not only with the normal functioning of the liver but also impact distant organs, including the brain. Prolonged liver dysfunction resulting from excessive alcohol consumption can lead to the...
Male and Female Sensitivity to Alcohol-Induced Brain Damage
Women are more vulnerable than men to many of the medical consequences of alcohol use. Although research has shown that male alcoholics generally have smaller brain volumes than nonalcoholic males, the few studies that have compared brain structure in...
Positron Emission Tomography: A Tool for Identifying the Effects of Alcohol Dependence on the Brain
To study alcohol's effects on the structure and function of the brain in living human beings, researchers can use various imaging techniques. Positron emission tomography (PET) is a functional imaging approach used to study the metabolism and physiology...
The Role of Thiamine Deficiency in Alcoholic Brain Disease
A deficiency in the essential nutrient thiamine resulting from chronic alcohol consumption is one factor underlying alcohol-induced brain damage. Thiamine is a helper molecule (i.e., a cofactor) required by three enzymes involved in two pathways of carbohydrate...
Using Magnetic Resonance Imaging and Diffusion Tensor Imaging to Assess Brain Damage in Alcoholics
Brain imaging using conventional magnetic resonance imaging (MRI) has revealed that several brain structures in people with a history of chronic alcohol dependence are smaller in volume than the same brain structures in nonalcoholic control subjects....
What Happened? Alcohol, Memory Blackouts, and the Brain
Alcohol primarily interferes with the ability to form new long-term memories, leaving intact previously established long-term memories and the ability to keep new information active in memory for brief periods. As the amount of alcohol consumed increases,...
