The Truth Behind Drinking Alcohol with a Concussion

Clinically Reviewed by: Charee Marquez, LMFT

Hello there! At California Prime Recovery, we are here to share vital information about a topic that concerns many: “The Truth Behind Drinking Alcohol with a Concussion.” In this blog post, we will explore the effects of alcohol consumption on individuals with a concussion, diving into medical insights and practical advice. So, let’s get started on this critical discussion.

What is a Concussion?

A concussion is a mild traumatic brain injury (TBI) that occurs when a blow to the head or body causes the brain to move rapidly within the skull. This movement can result in chemical changes in the brain and, in some cases, damage to brain cells. Concussions are common and can happen during various activities, such as sports, falls, or motor vehicle accidents.

Effects of a Concussion:

  1. Cognitive Effects:

    • Difficulty concentrating
    • Memory problems
    • Slowed reaction times
    • Confusion
    • Disorientation
  2. Physical Effects:

    • Headache or head pressure
    • Nausea or vomiting
    • Dizziness or balance problems
    • Sensitivity to light or noise
    • Fatigue or low energy
  3. Emotional and Behavioral Effects:

    • Irritability or mood swings
    • Anxiety or depression
    • Sleep disturbances (insomnia or excessive sleep)
  4. Communication Effects:

    • Difficulty communicating or finding the right words
    • Slurred speech
    • Communication challenges may contribute to social difficulties.
  5. Sleep Disturbances:

    • Changes in sleep patterns, such as difficulty falling asleep or excessive sleepiness.

Symptoms of a Concussion:

Symptoms of a concussion can vary widely among individuals and may not always be immediately apparent. They can manifest immediately after the injury or may develop over hours or days. Common symptoms include:

  1. Headache: A persistent or worsening headache is a common symptom.
  2. Dizziness or Balance Issues: Feeling unsteady or having difficulty maintaining balance.
  3. Nausea or Vomiting: Sensation of queasiness or vomiting.
  4. Sensitivity to Light and Noise: Discomfort or pain in response to light or noise.
  5. Fatigue: Feeling unusually tired or lacking energy.
  6. Confusion: Feeling disoriented or having difficulty concentrating.
  7. Memory Problems: Difficulty remembering events before or after the injury.
  8. Mood Changes: Irritability, mood swings, or changes in emotional well-being.
  9. Sleep Disturbances: Changes in sleep patterns, including difficulty falling asleep or excessive sleepiness.

It’s important to seek medical attention if a concussion is suspected, especially if symptoms are severe or worsen over time. While most concussions resolve with rest and time, a healthcare professional can assess the severity of the injury, provide guidance on recovery, and monitor for any complications.

Alcohol and The Brain

At its core, alcohol’s classification as a depressant underscores its capacity to slow down cognitive functions, resulting in a perceptible decrease in mental acuity. This phenomenon manifests as impaired decision-making, reduced attention span, and compromised memory recall. Concurrently, alcohol’s influence on the central nervous system contributes to disruptions in coordination, affecting motor skills and physical dexterity.

Delving into the intricacies of alcohol’s impact on brain function reveals its ability to modify neurotransmitter levels, an integral aspect of the brain’s communication network. The delicate balance of neurotransmitters, serving as chemical messengers between nerve cells, plays a pivotal role in regulating mood and behavior. By interfacing with this intricate system, alcohol introduces alterations that reverberate throughout the neural landscape.

One such neurotransmitter affected by alcohol is gamma-aminobutyric acid (GABA), an inhibitory messenger that promotes relaxation and a sense of calmness. Alcohol enhances the inhibitory effects of GABA, contributing to the sedative properties observed during moderate alcohol consumption. Simultaneously, alcohol influences the release of dopamine, a neurotransmitter associated with pleasure and reward, fostering the initial feelings of euphoria and contentment.

Can you Drink with a Concussion?

It is generally advisable to avoid alcohol consumption while recovering from a concussion. A concussion is a mild traumatic brain injury, and during the recovery period, the brain is in a vulnerable state. Alcohol can have various effects on the brain, including impairing cognitive function and coordination. Combining alcohol with the potential lingering effects of a concussion could exacerbate symptoms and delay the healing process.

Here are several reasons why it’s recommended to refrain from drinking alcohol during concussion recovery:

  1. Cognitive Impairment: Alcohol can further impair cognitive functions, such as memory, attention, and decision-making. Since a concussion already affects these cognitive processes, adding alcohol to the mix may intensify these impairments.

  2. Balance and Coordination: Concussions can disrupt balance and coordination, and alcohol can exacerbate these issues. Consuming alcohol may increase the risk of falls or accidents, especially if balance is already compromised.

  3. Increased Risk of Complications: Alcohol can dilate blood vessels and potentially increase the risk of bleeding. Since concussions involve injury to the brain, minimizing the risk of complications, including bleeding, is essential for a smooth recovery.

  4. Interference with Sleep: Alcohol can interfere with sleep patterns, and adequate rest is crucial for the brain’s recovery after a concussion. Disrupted sleep can impede the healing process and contribute to ongoing symptoms.

  5. Dehydration: Alcohol is a diuretic, meaning it can contribute to dehydration. Adequate hydration is important for overall health and recovery, and dehydration can exacerbate symptoms such as headaches.

  6. Masking Symptoms: Alcohol can mask or alter symptoms associated with a concussion. This can make it difficult to gauge the extent of recovery or identify worsening symptoms.

Individual responses to alcohol vary, and what may be tolerated by one person could have a different impact on another. However, as a general guideline, healthcare professionals often recommend abstaining from alcohol during the recovery period after a concussion.

Side Effects and Risks

Short-Term Effects and Risks of Drinking with a Concussion:

  1. Increased Cognitive Impairment:

    • Alcohol, even in moderate amounts, can exacerbate cognitive impairment associated with a concussion. This may lead to heightened confusion and difficulties in decision-making.
  2. Worsened Coordination:

    • Drinking alcohol can further impair coordination, which may already be compromised due to the effects of the concussion. This increases the risk of accidents or falls.
  3. Interference with Recovery:

    • Alcohol consumption may interfere with the brain’s natural healing processes after a concussion, potentially prolonging the recovery period.
  4. Dehydration:

    • Both alcohol and a concussion can contribute to dehydration. Consuming alcohol may intensify dehydration, leading to symptoms such as headaches and dizziness.
  5. Masking Symptoms:

    • Alcohol can mask or alter concussion symptoms, making it challenging to accurately gauge the extent of recovery or identify worsening symptoms.

Long-Term Effects and Risks of Drinking with a Concussion:

  1. Prolonged Recovery:

    • Regular alcohol consumption during concussion recovery may impede the healing process, leading to a prolonged recovery period.
  2. Increased Risk of Complications:

    • Alcohol’s effects on blood vessels may increase the risk of bleeding, which can be particularly concerning in the context of a recent concussion.
  3. Exacerbation of Mental Health Issues:

    • Combining alcohol with a concussion may contribute to or exacerbate mental health issues, including mood swings, irritability, and anxiety.
  4. Impaired Neurological Healing:

    • Chronic alcohol use can impair neurological healing, potentially hindering the restoration of normal brain function after a concussion.
  5. Addiction Risk:

    • Consistent alcohol consumption during concussion recovery may increase the risk of developing alcohol use disorder (AUD), leading to addiction and dependence.
  6. Increased Likelihood of Accidents:

    • The combination of alcohol and a concussion heightens the risk of accidents and injuries, further jeopardizing the individual’s overall well-being.
  7. Weakened Immune System:

    • Both alcohol and a concussion can weaken the immune system. Combined, they may make the individual more susceptible to infections and illnesses.
  8. Compromised Rehabilitation Efforts:

    • The impaired cognitive and motor functions associated with alcohol consumption may compromise rehabilitation efforts designed to address the effects of the concussion.

It’s crucial to note that the effects of alcohol on an individual recovering from a concussion can be unpredictable and vary based on factors such as the severity of the concussion, the individual’s overall health, and the amount of alcohol consumed. As a general guideline, healthcare professionals often recommend abstaining from alcohol during the recovery period after a concussion to optimize healing and minimize potential risks. Consulting with a healthcare provider for personalized advice is recommended in such situations.
