Electroconvulsive Therapy (ECT) in Addiction: Meaning, Effectiveness, Steps, Use Cases

Electroconvulsive Therapy (ECT) is a medical treatment that involves the use of controlled electrical currents to induce brief seizures in the brain. This procedure is primarily used to treat severe mental health conditions, such as major depression and bipolar disorder, particularly when other treatments have failed. In the context of addiction, ECT is explored as an adjunctive treatment for individuals who suffer from co-occurring disorders, such as severe depression or anxiety, that complicate their addiction recovery. 

ECT is used in addiction treatment primarily for individuals who have severe co-occurring mental health disorders that are resistant to other forms of therapy. It is particularly beneficial for patients with severe depression or bipolar disorder who have not responded to medications or psychotherapy. In these cases, ECT helps alleviate the psychiatric symptoms that exacerbate the addiction, making it easier for the individual to engage in and benefit from addiction treatment programs.

The effectiveness of ECT in treating co-occurring disorders in addiction has been supported by various studies, particularly for cases of treatment-resistant depression. According to the case report titled “Electroconvulsive Therapy for Depression When Substance Use Disorders are Comorbid” written by Silverio, A. et. al. 2019, and published by the Journal of Addiction Research & Therapy, ECT is considered one of the most effective treatments for severe depression, with response rates ranging from 60% to 90%. While ECT is not a standalone treatment for addiction, it helps by reducing the severity of these co-occurring conditions. ECT enhances the overall effectiveness of addiction treatment, contributing to better outcomes and reducing the likelihood of relapse.

What is Electroconvulsive Therapy (ECT)?

Electroconvulsive Therapy (ECT) is a medical procedure that involves passing a mild electric current through the brain, intentionally triggering a brief seizure. This procedure is done under general anesthesia and is used to treat severe mental health conditions, including depression, schizophrenia, and bipolar disorder. ECT is often used when other treatments are unsuccessful and when the full course of treatment is completed.

Electroconvulsive Therapy (ECT) was first introduced in 1938 by Italian neurologists Ugo Cerletti and Lucio Bini as a treatment for schizophrenia. Inspired by earlier experiments with inducing seizures, Cerletti and Bini developed ECT as a safer and more controlled method. Initially, ECT was widely adopted for various psychiatric disorders, but its early use without anesthesia led to significant discomfort, contributing to its controversial reputation.

Over the decades, advancements such as the introduction of anesthesia and muscle relaxants in the 1960s and 1970s significantly improved the safety and tolerance of ECT. These developments, along with better patient selection and informed consent practices, have rehabilitated ECT’s image. Today, ECT is recognized as a safe and effective treatment, particularly for severe, treatment-resistant cases of depression, bipolar disorder, and certain forms of psychosis. Despite its controversial past, ECT remains a valuable tool in modern psychiatry.

According to an article titled “Electroconvulsive Therapy (ECT)” published by Mental Health America, in the United States, ECT is administered to an estimated 100,000 people annually, primarily in psychiatric hospitals and general hospital psychiatric units. ECT stimulates a brief pulse (0.5 to 2 milliseconds) or ultra-brief pulse (less than 0.5 milliseconds). The procedure causes a seizure within the brain, which lasts for approximately a minute. ECT often works when other treatments are unsuccessful and when the full course of treatment is completed, but it is not effective for everyone.

What are the Steps in Electroconvulsive Therapy?

​​The process involves a series of well-defined steps to ensure the safety and effectiveness of the treatment. From the initial medical evaluation to the administration of controlled electrical currents, each step in ECT is designed to minimize risks and maximize therapeutic benefits. 

The steps in the ECT procedure are as follows:

1. Initial Preparation and Pre-Treatment Evaluations

Before beginning Electroconvulsive Therapy (ECT), patients undergo a thorough preparation process to ensure the treatment is appropriate and safe. This phase includes an extensive medical evaluation, which involves a detailed psychiatric assessment to confirm the diagnosis and determine if ECT is suitable. Additionally, a physical examination is conducted to evaluate the patient’s overall health and identify any potential risks or contraindications. Routine diagnostic tests, such as blood work and electrocardiograms (EKGs), are performed to ensure the patient will safely proceed with ECT. Informed consent is then obtained, where patients receive comprehensive information about the procedure, including potential benefits, risks, and side effects. Patients and their families are also educated on what to expect before, during, and after ECT to alleviate any concerns. Anesthesia preparation involves instructing patients to fast for several hours and reviewing current medications to make necessary adjustments or temporarily discontinue certain drugs.

2. Procedure Execution

The ECT procedure itself consists of several meticulously planned steps, each carried out by a team of healthcare professionals to ensure maximum safety and effectiveness:

• Anesthesia Administration: General anesthesia is administered to the patient to ensure they remain unconscious and free of discomfort during the procedure. A muscle relaxant is also provided to prevent physical convulsions. Vital signs, such as heart rate, blood pressure, and oxygen levels, are continuously monitored throughout the procedure to ensure patient safety.
• Electrode Application: Electrodes are carefully positioned on the patient’s scalp based on the specific treatment plan. Depending on the condition being treated, electrodes are placed either unilaterally (on one side of the head) or bilaterally (on both sides). Common configurations include right unilateral, bifrontal, and bitemporal, each selected to optimize treatment outcomes while minimizing potential side effects.
• Electrical Stimulation: A controlled electric current is delivered through the electrodes, stimulating the brain’s neurons and inducing a seizure, which is an essential part of the therapy. The current used is low, around 0.4 amps. The induced seizure lasts between 30 and 90 seconds and is closely monitored by medical professionals to ensure it is both safe and effective.

3. Post-Treatment Observation and Care

Following the ECT session, patients receive attentive care and monitoring to manage any immediate side effects and ensure a safe recovery:

• Anesthesia Recovery: After the procedure, patients are moved to a recovery area where they are closely observed as they wake up from anesthesia. Nurses monitor vital signs and manage common immediate side effects, such as confusion, headaches, and muscle soreness, with appropriate medications and care.
• Short-Term Observation: Medical staff conduct neurological assessments to evaluate the patient’s cognitive and physical status post-procedure, including checks on orientation, memory, and coordination. Emotional support is also provided during this period, as patients experience anxiety or disorientation.
• Ongoing Follow-Up and Care: Regular follow-up appointments are scheduled to track the patient’s progress, assess the effectiveness of the treatment, and manage any longer-term side effects. Based on the patient’s response, adjustments to the treatment plan, such as changes in the frequency of ECT sessions or the addition of psychotherapy and medication, are made to optimize outcomes.

What are the Physiological Changes Induced by Electroconvulsive Therapy (ECT)?

Electroconvulsive Therapy (ECT) triggers several physiological changes in the brain that contribute to its effectiveness in treating severe mental health conditions. These changes affect neurotransmitter levels, neuroplasticity, blood flow, and overall brain activity, enhancing mental health and cognitive functions.

1. Alterations in Neurotransmitter Levels:

ECT significantly impacts neurotransmitter levels, which play an important role in mood regulation and cognitive function, these alterations are central to the therapeutic effects of ECT.

• Serotonin: ECT increases serotonin levels, a key neurotransmitter involved in mood regulation. This increase contributes to improved mood and a reduction in depression symptoms, as detailed in “Mechanism Underlying the Therapeutic Effects of Electroconvulsive Therapy (ECT) on Depression,” written by Ishihara, K., and Sasa, M., and published in 1999.
• Dopamine: The therapy also affects dopamine levels, which are associated with pleasure and motivation. The article “Electroconvulsive Therapy Alters Dopamine Signaling in the Striatum of Non-Human Primates,” by Landau, A.M., Chakravarty, M.M., Clark, C.M., and colleagues, published in 2011, explains how ECT adjusts dopamine levels, enhancing motivation and overall mental well-being.
• Norepinephrine: ECT alters the levels of norepinephrine, a neurotransmitter involved in stress response and alertness. These changes help improve the patient’s ability to manage stress and maintain alertness during recovery.

2. Promotion of Neuroplasticity:

ECT promotes neuroplasticity, the brain’s ability to reorganize itself by forming new neural connections. This process is critical for recovering from mental health disorders. 

• Formation of New Neural Connections: The stimulation provided by ECT encourages the formation of new neural connections, enhancing cognitive functions and contributing to a more adaptable and robust neural network.
• Reorganization of Brain Networks: Neuroplasticity induced by ECT helps reorganize dysfunctional brain networks, aiding in the restoration of normal brain function. This reorganization is essential for overcoming the dysfunctional patterns associated with mental health disorders.

3. Increased Blood Flow and Metabolic Activity:

ECT enhances cerebral blood flow and increases metabolic activity, which are crucial for maintaining overall brain health. Improved blood flow ensures that the brain receives adequate oxygen and nutrients, facilitating better mental health outcomes.

4. Reduction of Abnormal Brain Activity:

ECT helps normalize abnormal brain activity, which is often present in mental health disorders. According to the article “Electroconvulsive Therapy-Induced Changes in Functional Brain Network of Major Depressive Disorder Patients: A Longitudinal Resting-State Electroencephalography Study” by Sun, S. et al., published in 2022, this normalization is vital for stabilizing brain function and reducing symptoms of mental illnesses. Consistent brain function supports long-term improvements in mental health.

When Is Electroconvulsive Therapy Shown to Be Effective? 

Electroconvulsive Therapy (ECT) has been demonstrated to be particularly effective for certain severe mental health conditions, often providing rapid and significant improvements when other treatments have failed. Over a thousand adults with severe, life-threatening depression, catatonia and other serious mental illnesses benefited from electroconvulsive therapy (ECT) in 2021, according to new data published by the Royal College of Psychiatrists. Here’s a detailed look at when ECT is shown to be effective:

1. Severe Depression: ECT is highly effective in treating severe major depression, especially in cases where symptoms are debilitating and have not responded to medications or psychotherapy. It is often used in cases of major depressive disorder with melancholic features or psychotic depression, where it provides rapid relief of symptoms.
2. Bipolar Depression: ECT shows high response rates in treating bipolar depression, particularly in individuals who do not respond to mood stabilizers or antidepressants. ECT is especially valuable for older adults with bipolar disorder, where age is a significant prognostic factor for a positive response.
3. Catatonia: ECT is one of the most effective treatments for catatonia, a condition characterized by motor disturbances, stupor, and unresponsiveness. It is also beneficial in treating other mental health disorders with catatonic features, providing quick and often complete resolution of symptoms.
4. Treatment-Resistant Conditions: ECT is considered a valuable option for treatment-resistant mental health conditions, where conventional treatments such as medications and therapy have not been successful. It is particularly effective in cases of treatment-resistant depression, bipolar disorder, and certain forms of schizophrenia.
5. Medicine Not Working or Desired: ECT is often used when traditional treatments, such as antidepressants, have not yielded positive results. It is also considered when patients are unable or unwilling to take medications due to side effects, lack of efficacy, or personal preference.
6. Need for Fast-Acting Treatment: ECT is particularly beneficial when a rapid, fast-acting treatment is needed, such as in cases of severe depression with a high risk of suicide. Its ability to provide quick symptom relief makes it a critical option for patients in acute crisis situations.

What is the Success Rate of Electroconvulsive Therapy?

ECT is approved by the U.S. Food and Drug Administration (FDA) and has been shown to be highly effective, giving some patients full reversal of severe depression symptoms. According to a study by Bailey, K. et. al. 2019 published by UT Southwestern Medical Center, ECT is approximately 80 percent effective when a patient is a good candidate. By comparison, about 50 percent of patients respond to antidepressant medication. ECT is primarily reserved for patients who do not respond to other types of therapy, but in some patients with severe symptoms, failure of other therapies is not a requirement.

How Does Electroconvulsive Therapy Compare with Other Therapies for Addiction?

Compared to other therapies like Cognitive Behavioral Therapy (CBT) or Medication-Assisted Treatment (MAT), ECT offers a unique approach by rapidly alleviating severe psychiatric symptoms that hinders recovery efforts. However, ECT is reserved for cases where other treatments have failed or where there is a need for immediate symptom relief, such as in cases of severe suicidal ideation.

Comparison of ECT with Other Therapies for Addiction

Why Does ECT Continue to Be Controversial Despite Its Effectiveness?

Electroconvulsive Therapy (ECT) remains a subject of controversy despite its effectiveness, primarily due to concerns surrounding memory loss, particularly events near the time of treatment. This controversy persists because ECT’s efficacy varies among individuals, not all patients respond to conventional ECT monotherapy, and there are ongoing debates about its effectiveness, with critics highlighting potential substantial costs.

In a 2005 paper published in the International Journal of Environmental Research and Public Health by CA Galletly, electroconvulsive therapy (ECT) is highlighted as a controversial treatment despite its proven efficacy and safety. This scrutiny persists, indicating ongoing debates surrounding the use of ECT. Moreover, a 2009 paper by A Kavanagh on PubMed highlights the enduring stigma and controversy associated with ECT despite being in use for 70 years, emphasizing the need for ongoing scrutiny and discussion surrounding its application. 

The lack of clear evidence regarding ECT’s effectiveness and its impact on the brain contributes to ongoing debates, with critics expressing concerns about potential brain damage. Stigmatization and negative portrayals in media, along with a history marked by abusive practices, further contribute to ECT’s controversial status. Gender concerns have also been raised, as the majority of ECT patients are women, impacting perceptions of gender equity and women’s mental health.

How Long Does ECT Memory Loss Last?

ECT causes retrograde amnesia, which means you will have gaps in your memory for events that occurred close in time to the course of ECT. This type of memory loss extends back several months or years. However, retrograde amnesia usually improves during the first few months after ECT.

A patient affected by anterograde amnesia is temporarily less able to remember what he or she has experienced for three months after treatment. Most people’s confusion clears up quickly, and memory loss usually goes away entirely within a few months. 

Why Is ECT a Last Resort?

Electroconvulsive Therapy (ECT) is often considered a last resort treatment option for severe mental health conditions, such as depression, schizophrenia, and bipolar disorder. This is because ECT involves sending an electric current to the brain, which causes a brief seizure within the brain. ECT causes side effects, such as memory loss, which is both short-term or long-term.

The potential for side effects and the invasive nature of the treatment make it a last-resort option for many patients and healthcare professionals. The perception of ECT as a last resort aligns with the stigma stemming from historical practices involving high doses of electricity administered without anesthesia, leading to memory loss and severe side effects. While traditionally viewed as a last resort, ECT’s role is expanding, challenging misconceptions, and offering hope to a broader range of patients. It’s crucial to reassess its perception in light of evolving research and consider it as a valuable option in comprehensive mental health care.

Is ECT Dangerous?

ECT is considered safe when administered by trained professionals in appropriate medical settings. However, like any medical intervention, ECT carries risks, commonly associated with temporary memory loss and difficulty learning. Some patients struggle to recall events preceding the treatment, with memory issues improving within a couple of months.

The decision to undergo ECT should be made after careful consideration of individual health factors and in consultation with a qualified healthcare provider. It is important to note that ECT is approved by the U.S. Food and Drug Administration (FDA) and is highly effective, particularly in cases where other forms of therapy have not been successful.

What Are the Odds of Relapse After ECT?

According to a study published in 2009 in the International Journal of Environmental Research and Public Health by Dr. G Rehor, the high relapse rate within 6 months after successful electroconvulsive therapy (ECT) poses a significant challenge for patients and psychiatrists.

A 2013 paper by A Jelovac found a 6-month relapse rate of 37.2% in patients treated with continuation ECT. Another meta-analysis revealed that, despite continuation pharmacotherapy, 51% of patients experienced relapse within 12 months post-successful ECT, with a majority relapsing within the initial 6 months.

What are the Side Effects of Electroconvulsive Therapy (ECT)?

Electroconvulsive Therapy (ECT) is a highly effective treatment for severe mental health conditions, but it does come with some side effects. ECT induces several physiological changes in the brain that contribute to its therapeutic effects. These changes span neurotransmitter levels, neuroplasticity, blood flow, and brain activity, according to Szuba, M. P. et al. 2000, “Physiological effects of electroconvulsive therapy and transcranial magnetic stimulation in major depression.” The side effects of ECT are categorized into short-term and long-term effects. 

Short-Term Side Effects:

• Confusion: Patients often experience confusion immediately following the procedure. This confusion lasts for a few minutes to several hours and is usually mild. The disorientation is a result of the induced seizure and anesthesia used during the treatment.
• Headaches: Headaches are a common short-term side effect after ECT. They occur due to the electrical stimulation and the induced seizure but are manageable with over-the-counter pain relievers.
• Muscle Aches: Muscle soreness, especially in the jaw and neck, occurs after ECT. This is due to the muscle contractions that happen during the seizure, despite the use of muscle relaxants. The discomfort usually subsides within a day or two.
• Nausea: Some patients experience nausea following ECT, which is often related to the anesthesia rather than the ECT itself. The nausea is usually temporary and will be treated with anti-nausea medications if necessary.
• Temporary Memory Loss: Memory loss is one of the most common side effects of ECT. Patients often forget events that occurred immediately before or after the treatment, a condition known as anterograde amnesia. This type of memory loss is short-lived, with memory function usually returning to normal within a few hours to days after the procedure.

Long-Term Side Effects:

• Persistent Memory Loss (Retrograde Amnesia): Long-term memory loss, particularly retrograde amnesia, occurs with ECT. This involves difficulty recalling events from weeks or months before the treatment. While many patients regain these memories over time, some experience permanent gaps in their memory.
• Cognitive Changes: In rare cases, patients experience long-term cognitive changes, such as difficulties with concentration, processing information, or executive function. These changes are usually subtle and improve over time, but for some individuals, they persist and require additional cognitive rehabilitation.
• Ongoing Memory Gaps: Some patients report long-lasting memory gaps where they are unable to recall specific events or information even months after completing ECT. These memory issues affect personal, social, and professional life, particularly if the gaps involve important events or details.

Is Electroconvulsive Therapy the Same as Shock Therapy?

Electroconvulsive Therapy (ECT) is often referred to as “shock therapy,” but the two terms reflect different connotations. ECT is the modern, medically supervised procedure used to treat severe mental health conditions like depression, bipolar disorder, and schizophrenia. The term “shock therapy” is outdated and generally refers to early forms of ECT that were administered without the safety measures we use today, such as anesthesia and muscle relaxants. Modern ECT is a highly controlled and refined procedure, unlike the crude methods historically associated with “shock therapy.” Despite the stigma surrounding the term, ECT is now considered a safe and effective treatment under proper medical supervision.

What are the Main Conditions Electroconvulsive Therapy Is Used For?

Electroconvulsive Therapy (ECT) is used to treat severe mental health conditions, especially when other treatments fail. It is most commonly applied in cases of major depressive disorder (MDD) with treatment resistance or suicidal ideation, making it one of the most effective options for severe cases. ECT is also effective for bipolar disorder, acute episodes of schizophrenia, catatonia, severe manic episodes, and psychosis related to Parkinson’s disease, particularly when other treatments are ineffective.

What Happens if You Drink Alcohol or Use Drugs After ECT?

Drinking alcohol or using drugs after Electroconvulsive Therapy (ECT) poses significant risks and should be strictly avoided. These substances interfere with the effectiveness of the treatment and exacerbate side effects such as confusion, memory loss, and cognitive impairment. They also increase the likelihood of seizures, which is particularly dangerous following ECT, as the brain is in a sensitive state post-treatment. Furthermore, alcohol and drugs undermine your overall mental health recovery and can lead to severe complications, making it crucial to avoid these substances during your treatment period. Always follow your healthcare provider’s advice regarding substance use after ECT.
