Acetaldehyde, the intermediate byproduct of alcohol metabolism, appears to be one of the major villians in the onset of alcoholic drinking. The trouble probably begins in the liver ...
... found that the same amount of alcohol produced very different blood acetaldehyde levels in alcoholics and nonalcoholics. Much higher levels were reached in alcoholics. Lieber theorized that this unusual buildup of acetaldehyde was caused in part by a malfunctioning of the liver's enzymes.
... took this acetaldehyde difference in alcoholics one step further. His studies confirmed that, in alcoholics, the breakdown of acetaldehyde into acetate -- the second step in alcohol metabolism -- is performed at about half the rate of "normal" i.e. nonalcoholic metabolism. It is this slowdown in metabolism which apparently causes acetaldehyde to accumulate.
... Heredity is clearly implicated in these studies ...
In summary, addiction to alcohol may, in part, be traced back to a liver enzyme malfunction which results in a buildup of acetaldehyde throughout the body. In the brain, these large amounts of acetaldehyde interact with the brain amines to create the isoquinolines. These mischievous substances may trigger the alcoholic's need to drink more and more alcohol to counter the painful effects of the progressive buildup of acetaldehyde.
... Accumulated evidence clearly indicates that alcoholism is hereditary ...
... The weight of evidence clearly links alcoholism to heredity ...
Goodwin's studies provide compelling evidence that alcoholics do not drink addictively because they are depressed, lonely, immature, or dissatisfied. They drink addictively because they have inherited a physical susceptibility to alcohol which results in addiction if they drink.
Furthermore, this evidence has profound implications for treatment. While it may be possible to teach the problem drinker how to drink in a more responsible way, the alcoholic's drinking is controlled by physiological factors which cannot be altered through psychological methods such as counseling, threats, punishment, or reward.
In other words, the alcoholic is powerless to control his reaction to alcohol.
