Electroconvulsive therapy (also known as electroshock) is a controversial treatment that has been used in psychiatry since the 1930s. Over the years, there have been significant advances in the techniques used and in our understanding of their effects . Despite the poor reputation it has acquired due to its depiction in popular culture, electroconvulsive therapy has proven to be a valuable tool in the treatment of certain serious psychiatric disorders. In this article, we will explore the current applications of electroconvulsive therapy, its mechanism of action, and possible associated side effects.
History and evolution of electroconvulsive therapy
Electroconvulsive therapy has its roots in the observation that epilepsy-induced seizures appeared to relieve psychotic symptoms in some patients. In 1938, the first modern electroconvulsive therapy was performed by Italian psychiatrist Ugo Cerletti and his colleague Lucio Bini. They used electrical currents to induce controlled seizures in psychiatric patients and observed significant improvements in their mental status.
Over the following decades, electroconvulsive therapy was refined and refined. Standardized protocols were developed for its administration, including the use of anesthesia and muscle relaxants to minimize patient discomfort during the procedure. Despite advances in its application, electroconvulsive therapy has been the subject of controversy and debate due to concerns about its safety and possible adverse effects.
Mechanism of action
The exact mechanism The action of electroconvulsive therapy is not fully understood, but it is believed to involve a combination of biochemical and neurological effects on the brain. During a treatment session, a brief electrical current is administered through the patient's scalp, inducing a controlled, generalized seizure in the brain.
It is thought that this widespread neuronal activation can trigger changes in neurotransmitter release and synaptic plasticity in specific brain regions, which in turn can positively affect the symptoms of certain psychiatric disorders. Additionally, it has been suggested that electroconvulsive therapy may have anti-inflammatory and neuroprotective effects that contribute to its therapeutic effects.
Clinical Indications
Over the years, electroconvulsive therapy has been used in the treatment of a variety of psychiatric disorders, especially in severe cases refractory to other treatments. Some of the most common clinical indications for electroconvulsive therapy include:
- Refractory major depression: Electroconvulsive therapy has been shown to be effective in relieving depressive symptoms in patients who do not respond to treatment. conventional pharmacological or psychotherapeutic therapy.
- Bipolar disorder: In some cases, electroconvulsive therapy is used to treat acute manic or depressive episodes in patients with bipolar disorder who do not respond to other treatments.
- Catatonic schizophrenia: Electroconvulsive therapy may be beneficial in the treatment of catatonia associated with schizophrenia and other psychotic disorders.
Patient selection and treatment protocol
Proper patient selection for electroconvulsive therapy is crucial to ensure its effectiveness and safety. Before starting treatment, extensive evaluations are performed to determine a patient's suitability and develop a personalized treatment plan. Some of the factors to consider include the severity of symptoms, previous medical history, response to previous treatments, and the presence of medical comorbidities.
The typical treatment protocol for electroconvulsive therapy consists of a series of sessions that are carried out under general anesthesia and medical supervision. During each session, a controlled electrical current is applied through electrodes placed on the scalp, inducing a therapeutic seizure. The duration and frequency of sessions may vary depending on the patient's individual needs and response to treatment.
Possible side effects and controversies
Despite its effectiveness in treating certain psychiatric disorders, electroconvulsive therapy may be associated with side effects and controversies. Some of the possible adverse effects of electroconvulsive therapy include:
- Memory and cognition problems: Some patients experience short-term memory difficulties and other cognitive problems after undergoing electroconvulsive therapy. These effects are usually temporary and tend to improve over time.
- Physical effects: During an induced seizure, muscle contractions and minor injuries to the muscles, bones, or joints may occur. However, these effects are usually minimal and do not usually cause serious complications.
- Stigma and negative perceptions: Due to its inaccurate representation in the media and popular culture, electroconvulsive therapy is often surrounded by stigma and negative perceptions. This can make it difficult for patients to access this potentially beneficial treatment.
Controversies and regulation
Electroconvulsive therapy has been the subject of debate in terms of its use, regulation and ethics. Some of the most common controversies include concerns about informed patient consent, inappropriate administration of treatments, use in vulnerable populations, and lack of long-term follow-up of treatment effects.
To address Given these concerns, strict guidelines and regulations have been developed for the administration of electroconvulsive therapy in clinical settings. This includes obtaining full informed consent from the patient or his or her legal representative, supervision by a trained medical team, and careful monitoring of the effects of treatment.
Conclusions and future considerations
In summary, electroconvulsive therapy is an effective therapeutic tool in the treatment of certain severe psychiatric disorders resistant to other treatments. Despite its poor reputation and associated controversies, electroconvulsive therapy has proven effective in relieving depressive, manic, and psychotic symptoms in many patients.
To ensure the safety and effectiveness of electroconvulsive therapy, it is essential continue developing research around its mechanism of action, long-term effects and best clinical practices. Additionally, it is important to address the stigma and negative perceptions surrounding this treatment, so that patients who could benefit from it can access it in an informed and non-judgmental manner.
Ultimately, therapy Electroconvulsive therapy continues to be a valuable resource in the field of psychiatry, and its appropriate and ethical use can make a difference in the quality of life of many people struggling with serious mental disorders. The combination of scientific advances, effective regulations and public awareness can contribute to improving the acceptance and accessibility of this treatment for the benefit of patients who need it.
