According to a global survey in 2018, more than 107 million people struggle with alcohol abuse; 1/3 of these also suffer from a psychiatric disorder. (Source: Alcohol Rehab Guide), like depression or bipolar disorder, alcohol dependence also induces a chemical imbalance in the brain – leading to a risk of mental illness. 
The overlapping connection between alcoholism and mental health makes it hard to quit alcohol as many cannot tolerate withdrawal and relapse. Studies have shown that long-term alcohol abuse can cause brain impairment, emotional instability, and worsen depression. 
Getting professional help to achieve sobriety may help you win the battle against alcohol abuse and depression.
Alcohol Abuse And Mental Health
People usually drink alcohol to indulge, release stress and overcome negative emotions. For many, drinking serves as an escape from day to day problems – eventually leading to addiction, becoming alcoholics.
Some triggering factors for alcohol dependence are:
- Emotional breakdown
- Emotional distress
- Financial struggle
- Alcohol abuse
- Mental relapse
- Mental health disorders like depression, bipolar disorder, and anxiety
Symptoms And Side Effects
Apart from the adverse effects on personal life, people with a drinking problem are at risk of serious health concerns – weight gain, pancreatitis, heart and liver disease, to name a few.
Besides affecting the chemical imbalance, over-drinking changes the brain itself. Thus, alcohol abuse also affects cognitive performance.
Here are the side effects of long-term drinking on the human brain:
- Slows Central Nervous System – Alcohol slows down messages between the brain and the body, eventually slowing down your central nervous system.
- Prefrontal–striatal–limbic circuit – Alcohol harms this part of the brain that controls decision-making, stress, and emotions. 
- Ventral striatum – This part of the brain gets damaged and reduces the feel-good chemical (dopamine), causing mood swings and depression. 
- Prefrontal cortex and orbitofrontal cortex – People with a drinking problem have fewer brain cells or grey matter – thus, affecting their decision-making abilities. [6, 7]
Relationship Between Alcohol And Depression
On the other hand, mental health problems can also encourage alcohol abuse. Studies show that 47% of people with mental health issues also abuse alcohol and drugs. (Source: Boardwalk Recovery Centre)
Alcohol and depression are often co-occurring, meaning the two disorders coincide and intertwine towards a bigger issue.
Common symptoms of depression in early sobriety include:
- Feeling low, sad, and hopeless
- Overthinking and cycling negative thoughts
- Insomnia and restlessness
- Difficulty getting out of bed
- Feeling anxious and fearful
- Chronic pains, lethargy, and immense fatigue
- Poor eating habits (loss of appetite or overeating)
- Inability to focus and pay attention
- Having suicidal thoughts or suicidal idealization
Types of Depression in Sobriety
Impact of Sobriety/Quitting Alcohol on Depression
Depression in early recovery may occur in rare cases, but some also experience Day drunk syndrome – reflecting impulsive and dysfunctional alcoholic behaviors even after quitting alcohol.
How Sobriety Helps Depression
- Regulates Excitatory Neurotransmitters
Quitting alcohol dependence reverses these changes and regulates the neurotransmitters, putting the body in its natural state.
- Normalizes Dopamine Levels
Thus, when you quit drinking, you start feeling sad and depressed due to the reduction in dopamine. Over time the brain begins to normalize dopamine levels.
- Serotonin Production Increases
Alcohol boosts serotonin, but the long-term heavy consumption of alcohol decreases serotonin, leading to depression symptoms. Quitting alcohol normalizes serotonin production, leading to better emotional health.
How To Quit Alcohol and Treat Depression?
Want to develop an alcohol-free lifestyle and achieve long-term sobriety? Quit.
Quitting is the only way to treat and get rid of alcohol addiction. Joining AA meetings and reaching a professional for help. Since alcohol affects the mind, get help from a professional Psychiatrist.
An alcohol addiction psychiatrist will diagnose and treat the causes of alcohol abuse and alcoholism by:
- evaluating your mental health
- finding the triggering factor
- recommending effective treatment options
- assisting with the treatment
When it comes to dual diagnosis, i.e., suffering from both depression and alcoholism. Such issues have to be treated separately but under interconnected conditions.
Here are proven-effective treatments for alcohol-induced depression.
