 Alcohol in Moderation (of Course!) Saves You from Depression
Here's some news for those teetotalers! Studies have shown that alcohol is great for you- but, of course, in moderation. And the reason? It might just save you from sinking into depression.

According to a new research, stopping drinking, especially at moderate level, may lead to health problems including depression and a reduced capacity of the brain to produce new neurons, a process called neurogenesis.

"Our research in an animal model establishes a causal link between abstinence from alcohol drinking and depression," said study senior author Clyde W. Hodge, Ph.D., professor of psychiatry and pharmacology in the UNC School of Medicine.

"In mice that voluntarily drank alcohol for 28 days, depression-like behavior was evident 14 days after termination of alcohol drinking. This suggests that people who stop drinking may experience negative mood states days or weeks after the alcohol has cleared their systems," Hodge added.

In the study, mice were tested for depression-like behavior using a widely recognized method called the Porsolt Swim Test.

The mice are placed inside a beaker filled with water and allowed to swim for six minutes. Mice are good swimmers and have no problem completing this task. The amount of time they spend immobile (floating and not swimming) is measured as an index of despair or depression-like behavior. The more time a mouse spends immobile, the more "depressed" it is thought to be.

"This research provides the first evidence that long-term abstinence from moderate alcohol drinking - rather than drinking per se - leads to a negative mood state, depression," Hodge said.

The study also found that the emergence of depression was associated with a profound reduction in the number of neural stem cells, i.e. the cells that will become neurons, and in the number of new neurons in a brain region known as the hippocampus.

This brain region is critical for normal learning and memory, and recent studies show that the development of neurons in the hippocampus may regulate mood, Hodge said.

According to Hodge, the negative mood state in mice may represent depression in humans and appears to be linked to a diminished capacity of the brain to form new neurons.

"Thus, people who drink moderate alcohol socially, or for potential health benefits, may experience negative mood or diminished cognitive abilities due to a loss of the brain's ability to form new neurons," he said.

But the study also found that treatment with an antidepressant drug during 14 days of abstinence prevented the development of depression and restored the capability of the brain to produce new cells.

The study has been published in the journal Neuropsychopharmacology.

The results of this study do not show (as suggested by the title) that moderate alcohol prevents depression. To the contrary, this study showed that profound changes can occur in the brain (reduced neurogenesis) and mood (depression-like symptoms) weeks after moderate alcohol exposure. Similar effects are seen after heavy drinking in alcoholics who report that negative affect is a primary reason they start drinking again. Thus, this study shows that pathological conditions that exist in alcoholism may begin early in a person's drinking history – even after moderate use. Using alcohol to alleviate a negative mood state is dangerous and could lead to addiction.
