Electroconvulsive therapy has been a treatment of choice for various psychiatric illness for decades. Over time due to improvements in the technical parameters, administration technique and advent of newer drugs, electroconvulsive therapy has transformed into a safer, tolerable and effective form of treatment.
Newer form of therapy utilizes narrower pulses of stimulation, under anesthesia to produce the desired effect. This form of treatment is known as Brief Pulse Therapy (BPT).
Brief Pulse Therapy is considered as the “GOLD STANDARD” of care in many conditions in Psychiatry.
For years now, the cinematic portrayal of ECT has vilified a necessary medical procedure.
A power packed performance where the person is AWAKE and shown tied up while being electrocuted, the scene is further dramatized by painful screaming and uncontrollable jerking followed by froth coming out of the mouth and at the end of the procedure the “actor” is shown to be completely disoriented. This exaggerated depiction has resulted in people equating ECT as a last ditch effort that is truly a punishment.
The visual medium and popularity of movies has been responsible for widespread misinformation across the globe, influencing the way millions of people perceive ECT. The only appropriate depiction came in the Hollywood Crime Drama “Homeland”, where Carrie Mathison, a CIA agent, would undergo this procedure for her Bipolar Mood Disorder.
In fact, many clinicians have covered these aspects in scientific papers to appeal to the television community to alter this depiction, in hope to de-stigmatize the procedure so that those in need, feel no fear in seeking out for help.1
ECT works in a number of ways. The exact mechanism is not entirely clear.
ECT’s most significant effect is on the neuro-endocrine balance in the brain. By increasing/decreasing the production of certain neurotransmitters, ECT enables the maintenance the homeostasis, which reduces illness severity and enhances resilience.
When done as an OPD procedure, the patient does not require admission (after a prior consultation) and can come at the time of BPT, and is free to go after a few hours of the procedure.
During the entire procedure the patient’s airway and ventilation is maintained and vital signs are continuously monitored.
NOTE : Emergency drugs are always kept handy to effectively deal with any complication, if they arise.
| Myths | Facts |
|---|---|
| BPT is given to an AWAKE patient | Patient is under anesthesia for the entire procedure. BPT is given after anesthesia has been given. |
| “Electrical Shock” is given for a long time. | Controlled electrical stimulation is given using a specialized machine. The average duration of the stimulus is for a few seconds (1-3 seconds). |
| BPT causes permanent memory loss | BPT is not associated with any permanent damages to memory or to other brain structure. |
| BPT resets/factory resets the brain | BPT causes a complex chain of changes in the chemical balance of the brain, which leads to recovery from illness. It does not alter the brain structure in any way. |
| A person goes crazy after receiving a course of BPT | BPT is the cure to an illness, and does not cause the illness. |
| After a course of BPT, the patient becomes dependent on BPT. | No form of dependence occurs after a course of BPT. |
| BPT is given to patients who have serious mental illnesses. | BPT can be given to any patient with mental illnesses, irrespective of the severity of the illness. |
Most frequently asked questions, is at what stage of the illness is ECT required for me. The answer depends on a number of clinical factors, but to give a brief idea.
| CONDITIONS REQUIRING ECT | |
|---|---|
| Melancholic Depression (Severe Depression) | Bipolar Mood Disorder (Mania/Depression) |
| Depression with Psychotic Features (Paranoia) | Increasing the time period between two episodes of Bipolarity |
| Aggression/Severe Irritability | Previous History Of Good Response To ECT |
| Schizophrenia (Positive Symptoms) | Improving residual symptoms |
| SUICIDAL THOUGHT/ACTIONS/ATTEMPTS | |
Administration of ECT causes a reduction in overall magnitude of illness.
This allows the existing medications to act in a more effective manner, thereby reducing the need to increase or change medication regimen.
The newer form of neurostimulation is Repetitive Transcranial Magnetic Stimulation (rTMS). This technique employs magnetic strength to alter brain activity.
It is noninvasive and associated with minimal side effects. However, efficacy wise it is inferior to ECT in all parameters. Also, other than in depression, its role in other psychiatric illness is very limited.
The table below will describe in detail the difference in effectiveness between ECT and rTMS in a patient of depression.
