How can alcoholism lead to depression and anxiety?

Alcoholism is closely linked to the development of depression and anxiety through both direct physiological effects on the brain and the broader consequences of chronic substance dependence.12

As a depressant that affects the central nervous system, alcohol can paradoxically worsen objectively observed depression, even when individuals use it in an attempt to improve their mood. While alcohol may provide temporary feelings of relaxation or guilt reduction, these are often subjective; in reality, its impact on brain function can exacerbate depressive states.3

Furthermore, substance dependence often leads to withdrawal symptoms—including anxiety and tremors—when alcohol intake is reduced or ceased. Chronic alcohol abuse is also associated with a range of psychological disorders, including emotional instability and impaired cognitive function. Fortunately, research indicates that after a period of abstinence, there is often marked improvement in tests assessing chronic depression and anxiety, as well as recovery from associated cognitive impairments.21
