Depression and abstinence: when alcohol leaves its mark

Alcohol use disorder (AUD) is a complex condition affecting millions of people worldwide, with profound consequences on both mental and physical health. Among the commonly associated comorbidities, depressive symptoms play a central role, significantly impacting patients' quality of life and their ability to maintain long-term abstinence. These depressive symptoms also increase the risk of relapse, creating a challenging vicious cycle to break.

While alcohol abstinence generally leads to an improvement in depressive symptoms due to reduced neurotoxic effects of alcohol on the brain, some patients continue to experience depression even after several weeks without drinking. This phenomenon raises important questions about the factors contributing to the persistence of depressive disorders in this population.

This study aims to better understand these mechanisms by exploring the link between pre-abstinence drinking behaviors and the persistence of depressive symptoms after four weeks of abstinence.

Alcohol: A Double-Edged Escape?

A total of 102 patients with initial depressive symptoms (QIDS-SR-J score ≥ 6) hospitalized for AUD were included in the study. After four weeks of abstinence, participants were divided into two groups:

• Remission group (51 patients): No persistent depressive symptoms.
• Persistence group (51 patients): Persistent depressive symptoms.

Drinking behaviors were assessed using the DBP-20 questionnaire, which measures factors such as automaticity, social use, and reliance on alcohol to manage negative emotions. Advanced statistical analyses, including logistic regression and ROC curves, were used to identify predictors of persistent depression.

The findings demonstrated that patients who used alcohol as a strategy to cope with negative emotions had a significantly higher risk of persistent depression after abstinence. High scores on the "coping with negative emotions" subscale were associated with elevated rates of depression, particularly among unemployed patients. Conversely, patients with automatic drinking habits showed more frequent natural remission, suggesting that their depressive symptoms were more alcohol-induced.

Identified risk factors include:

• Low education level.
• Unemployment.
• Alcohol consumption motivated by emotional regulation.

The results also highlight the importance of offering therapeutic alternatives, such as cognitive-behavioral therapies, to help these patients manage their emotions without relying on alcohol.

Toward Tailored Rehabilitation? 

AUD is a complex mental health issue, often accompanied by depressive symptoms that severely impair patients' quality of life. For some, these symptoms persist despite abstinence, increasing the risk of relapse and complicating their treatment.

This study explored the role of drinking behaviors in the persistence of depressive symptoms after four weeks of abstinence. The findings underscore that using alcohol as an emotional coping mechanism is a key factor contributing to persistent symptoms. These conclusions emphasize the importance of assessing the underlying motivations for alcohol use to tailor therapeutic strategies to patients' needs.

However, the study has limitations, including a small sample size and the lack of long-term follow-up, which prevent generalization of the results. Larger-scale research with diverse cohorts and extended follow-ups is necessary. Enhancing rehabilitation programs by combining psychosocial therapies and tools like the DBP-20 could better identify at-risk patients. A personalized approach could reduce persistent depression and prevent relapse, providing more comprehensive and effective care.
