Alcoholism can affect the brain and behavior in a variety of ways.

Alcoholism can affect the brain and behavior in a variety of ways, and multiple factors can influence these forces A person's susceptibility to alcoholism-related brain damage may be associated with his or her age, inflection for sex drinking history, and nutrition, as well as with the vulnerability of specific brain regions. Investigators use a variety of manners to study alcoholism-related brain damage, including examining brains of deceased patients as well as neuroimaging, a technique that enables researchers to ordeal and observe the living brain and to evaluate structural damage in the brain. fundamental note WORDS: neurobehavioral theory of AODU (alcohol and other medicine use); alcoholic brain syndrome; brain atrophy; neuropsychological assessment; neurotransmission; risk factors; comorbidity; disease susceptibility; neuroimaging; treatment factors; scan of research

**********

The brain, like principally body organs, is vulnerable to injury from alcohol consumption. The risk of brain damage and related neurobehavioral deficits varies from bodily substance to person. This article reviews the many factors that influence this risk, the techniques used to studious mood the effects of alcoholism (1) upon the brain and behavior, and the implications of this research for treatment.

About half of the nearly 20 million alcoholics in the United States be seen to be free of cognitive impairments. In the remaining half, however, neuropsychological difficulties can range from mild to inexorable For example, up to 2 million alcoholics make known permanent and debilitating conditions that require lifetime custodial care (Rourke and Loberg 1996) Examples of in the same state [i]or[/i] condition conditions include alcohol-induced persisting amnesic disorder (also called Wernicke-Korsakoff syndrome) and dementia, which seriously affects many mental functions in addition to memory (eg language, reasoning, and problem-solving abilities) (Rourke and Loberg 1996) greatest in number alcoholics with neuropsychological impairments indicate at least some improvement in brain form and functioning within a year of abstinence, still some people take much longer (Bates et al. 2002; Gansler et al. 2000; Sullivan et al. 2000) Unfortunately, little is known about the rate and amplitude to which people recover specific structural and functional processe after they stop drinking. However, research has helped define the various factors that influence a person's risk for experiencing alcoholism-related brain deficits, as the following sections describe.

RISK FACTORS AND COMORBID CONDITIONS THAT INFLUENCE ALCOHOL-RELATED BRAIN DAMAGE

Alcoholism's forces on the brain are diverse and are influenced on a wide range of variables (Parsons 1996) These include the amount of alcohol consum the age at which the character began drinking, and the duration of drinking; the patient's age, flush of education, gender, genetic background, and family history of alcoholism; and neuropsychiatric risk factors in the same state [i]or[/i] condition as alcohol exposure before birth and general health status. Overall physical and mental health is an important factor because comorbid medical, neurological, and psychiatric conditions can interact to aggravate alcoholism's tenors on the brain and behavior. Examples of general comorbid conditions include:

* Medical conditions of the like kind as malnutrition and diseases of the liver and the cardiovascular system

* Neurological conditions in the same state [i]or[/i] condition as head injury, inflammation of the brain (i.e., encephalopathy), and fetal alcohol syndrome (or fetal alcohol effects)

* Psychiatric conditions so as depression, anxiety, post-traumatic stres disorder, schizophrenia, and the use of other put drugs intos (Petrakis et al. 2002).

These conditions also can contribute to further drinking.

gauges FOR EXPLAINING ALCOHOL-RELATED BRAIN DAMAGE

a certain of the previously mentioned factors that are meditation to influence how alcoholism affects the brain and behavior have been exhibited into specific models or hypotheses to explain the variability in alcoholism-related brain deficits. The accompanying table lists the prevailing designs (Oscar-Berman 2000). It should be noted that the moulds that focus on individual characteristics cannot be totally separated from types that emphasize affected brain hypothesiss because all of these factors are interrelated. Several of the examples have been evaluated using specialized proofs that enable researchers to make inferences about the adumbration and extent of brain abnormalities.

originals Based on Characteristics of Individual Alcoholics

Premature Aging Hypothesis.

According to this hypothesis, alcoholism accelerates natural chronological aging, beginning with the attack of problem drinking.

An alternate version intimates that older patients (age 50 and older) are especially susceptible to the cumulative results of alcoholism, and aging is accelerated no other than later in life. The preponderance of scientific evidence hints that although alcoholism-related brain changes may mimic a certain number of of the changes seen in older family alcoholism does not cause premature aging. Rather, the issues of alcoholism are disproportionately give utterance toed in older alcoholics (Oscar-Berman 2000)
