Depression is defined as “A mental state of depressed mood characterized by feelings of sadness, despair and discouragement.” Studies over the last few years have shown that alcoholism and depression are often interrelated. Those who suffer from alcoholism can develop depression and vice versa.
Many who suffer from depression develop alcoholism because alcohol consumption and its effects can cause a euphoric and relaxed state. In other words, they try to “drink away” their negative mood. The euphoric symptoms of these effects are only temporary: once the effects of the alcohol begin wearing off, the person's depression becomes worse which may lead to additional alcohol consumption.
Alcoholism can also contribute to developing depression because the alcohol has a negative effect on neurotransmitter production and levels in the brain. These neurotransmitters such as serotonin not only control our movements but also our emotional responses and our ability to feel happy. Disruption of chemical processes in the brain due to alcohol consumption often results in depressive incidents.
