Neurostimulation
Toronto Private Hospital's comprehensive mental health treatment model is further enhanced by effective, proven and alternative treatments for depression.
These established services, such as Repetitive Transcranial Magnetic Stimulation (TMS) and Electroconvulsive Therapy (ECT), already administered in private suites at Healthe Care's other specialised mental health facilities are particularly effective for higher acuity cases of depression, and for those who may not have responded to antidepressant medication treatment.
Repetitive Transcranial Magnetic Stimulation (rTMS)
Repetitive Transcranial Magnetic Stimulation (rTMS) is a proven treatment for depression and possibly other psychiatric disorders. Studies have clearly shown that rTMS is an effective treatment for patients with depression.
What is rTMS?
Repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive procedure that involves the focused application of magnetic energy to superficial regions of the brain, inducing small electrical currents. During an rTMS procedure, an electrical current passes through a small coil placed close to the scalp. This current induces a magnetic field. The magnetic field can pass into the brain without resistance. If the magnetic field is of sufficient strength, it will stimulate electrical activity in nerves below the coil, that is, in superficial regions of the brain.
rTMS in Depression
Studies have evaluated the role of rTMS in the treatment of depression since the mid-1990s. These studies have clearly shown that rTMS is more effective than a placebo type of stimulation, especially in patients who have not responded well to antidepressant medication treatment.
How is rTMS administered?
rTMS is administered as a course of 20 treatments which are generally administered on a daily basis. Sessions usually take between 20 and 45 minutes per day depending on the protocol being utilised. During an rTMS session a patient is awake, alert and aware of what is happening at all times and is seated in a comfortable chair. Before the treatment course begins, the treating Psychiatrist will undertake threshold testing to ensure that the correct prescription is tailored for the patient for the treatment sessions.
You may feel small twitches in the hand during this procedure. It is not painful. This procedure is done to establish how high the machine intensity needs to be sent to affect the brain in an individual patient.
During the treatment itself, a coil is usually placed on the scalp (held by hand or with a coil stand) near the front region of the brain. This may be on the left or right depending on how the treatment is being given. The coil is connected to a machine that generates the electrical current. You may feel a tapping sensation under the coil (this occurs due to a twitch produced in scalp muscles as the magnetic field crosses into the brain). The magnetic field can also stimulate small nerves around the head and face, producing a muscle twitch in the forehead, face or eye region.
Antidepressant medications may be prescribed, especially to try and prevent relapse after the treatment with rTMS finishes.
Treatment Program
Toronto Private Hospital has an accredited team of Clinicians who administer rTMS as part of an inpatient admission program. Average length of stay is 21 days. During this time, you will be enrolled in a depression specific psychoeducation program, designed specifically to provide the skills and strategies to support your recovery.
Electroconvulsive Therapy (ECT)
ECT is a medical treatment for severe depression, bipolar disorder and psychotic illnesses such as schizophrenia.
What is ECT?
Electroconvulsive therapy (ECT) has been used across the world as an effective treatment for some severe mental illnesses for many years. The value of this treatment is known internationally and the method has been improved in recent years to get better results and fewer side effects.
Modern ECT is safe for most people (exceptions are now rare) and for some conditions, ECT is the best and safest treatment option. ECT will not be given to anybody deemed unfit for treatment and your physical health such a cardiac condition will be assessed as a part of this. ECT is not painful.
A carefully controlled electrical current is passed through the scalp and induces a seizure throughout the brain, affecting the brain’s electrical activity and producing an improvement in depressive and psychotic symptoms.
Why do I need ECT?
ECT is good for major depression, mania and some forms of schizophrenia. In depression, it is particularly good for those people who are very depressed and those who may be suicidal. It is used in the treatment of depression when antidepressants have not worked. It is also used for patients who have bad side effects with antidepressants or whose medical condition means they can’t take antidepressants safely.
Your Doctor will discuss with you why ECT is the best treatment for you and what other relevant treatment options are available.
ECT can help you by treating your condition which may also help you in the lifting of depression and better thinking ability.
What do I need to do before ECT?
Before your procedure, you will need to have some tests including an ECG, chest x-rays, a physical examination, and a blood test(s). Your Psychiatrist will explain these tests and when to have them.
You must fast (eat no food or drink any fluid or water) for several hours before the ECT treatment. If you do eat or drink anything during the fasting period it is important that you tell Nursing and Medical staff.
If there is any chance you may be pregnant please advise your Psychiatrist.
How is ECT administered?
Treatment takes place in the hospital's ECT Suite and only takes a few minutes.
You will have a short general anaesthetic so you will be asleep and not feel or remember the treatment. An Anaesthetist will give the anaesthetic. You will also be given a muscle relaxant to keep any muscle reaction to the ECT at a safe level.
A Psychiatrist who has specialised training in ECT performs the treatment. The Psychiatrist puts the treating electrodes to your scalp and passes a measured amount of electricity to a part of the brain to cause a seizure. The seizure will last about one minute.
During the treatment, the Anaesthetist will continue to give you oxygen via a mask and monitor your heart rate and oxygen level. You will be asleep during all of this treatment, which means that you will not feel or remember any of the actual treatment.
Within a few minutes, the anaesthetic medication will have worn off and you will wake up. During this time, you will be moved to the recovery room where you will monitored until you are awake enough to return to your ward (or wait to be taken home if you are having day procedure ECT). You will usually be ready for a meal about 15–20 minutes after the treatment.
The anaesthetic will affect your judgement for the first 24 hours following treatment. During this time YOU MUST NOT:
- Drive any type of vehicle
- Operate machinery including cooking implements
- Make important decisions or sign a legal document
- Drink alcohol, take other mind-altering substances, or smoke as these drugs may react with the anaesthetic drugs
What is a course of ECT?
ECT is usually administered two or three times a week. It is not possible to determine exactly how many treatments will be required. You will be reviewed regularly by your Psychiatrist to determine your progress. Some patients improve after three or four treatments others may need as many as 12 and very occasionally more.
Is there evidence that ECT works?
There is clear scientific evidence that ECT is effective in improving depressive and psychotic symptoms. Approximately 80 per cent of depressed patients who receive ECT have a good response. People commonly report that ECT makes them "feel like themselves again" and "as if life is worth living again."
