How does ECT change brain chemistry?


Sharing is Caring


It may promote changes in how brain cells communicate with each other at synapses and it may stimulate the development of new brain cells. ECT may flood the brain with neurotransmitters such as serotonin and dopamine, which are known to be involved in conditions like depression and schizophrenia.

What is the science behind ECT?

During ECT, a small amount of electrical current is passed through the brain while the patient is under general anesthesia. This current causes a seizure that affects the entire brain, including the parts that control mood, appetite, and sleep.

Does ECT alters the structure and chemistry of the brain?

In psychiatric disorders alterations in volume of brain structures has been consistently reported. Studies have also demonstrated ECT to trigger changes in volume of whole brain as well as its components such as gray matter, white matter and other brain structures.

What is ECT most commonly used for?

Electroconvulsive therapy (ECT) is a medical treatment most commonly used in patients with severe major depression or bipolar disorder that has not responded to other treatments.

What is the mechanism of action of ECT?

The main mechanism of action in electroconvulsive therapy (ECT) is the induction of a generalized clonic seizure. This seizure is triggered by the delivery of an electric current to the patient’s brain using electrodes placed on the patient’s head.

Does ECT increase serotonin?

Conclusion. Altogether, our results showed that serum serotonin levels significantly increase following ECT in MDD patients.

What is the effectiveness of ECT?

Electroconvulsive therapy (ECT) is a highly effective treatment for depression. Research indicates that ECT can be significantly more effective than pharmacotherapy, with 50% to 60% of patients achieving rapid remission of depression after a course of ECT compared with 10% to 40% with pharmacotherapy/psychotherapy.

Is ECT still used today?

Using ECT to Treat Depression Effective treatments for depression include counseling, psychotherapy, and prescription medications. However, for an estimated 100,000 people a year in the United States, like Neville, these options fall short. And for them, ECT is safe, reliable, and effective.

What does ECT do for depression?

With ECT, an electrical stimulation is delivered to the brain and causes a seizure. For reasons that doctors don’t completely understand, this seizure helps relieve the symptoms of depression. ECT does not cause any structural damage to the brain.

What part of the brain is targeted in ECT?

Considering ECT as a kind of fast and effective treatment, the amygdala could be used as an important target in the treatment of MDD.

Does ECT destroy brain cells?

The review of literature and present evidence suggests that ECT has a demonstrable impact on the structure and function of the brain. However, there is a lack of evidence at present to suggest that ECT causes brain damage.

Does ECT affect intelligence?

However, former patients have publicly testified that ECT can result in a very significant (>30 point) permanent decrement in IQ score (Food and Drug Administration, 1982; Andre, 2001; Cott, 2005: p. 5) and have documented the claims by extensive neuropsychological evaluation.

What are the two types of ECT?

  • Bilateral ECT. This is when the current is passed through both sides of your head.
  • Unilateral ECT. This is when the current is only on one side of your head.

Why is BP cuff used in ECT?

The ‘cuff’ method provides a simple and reliable index of the occurrence of a generalized convulsion. A sphygmomanometer cuff is applied to the arm and inflated to ~ 40-50 mm Hg above the systolic BP before administration of the muscle relaxant [9].

What is the difference between ECT and TMS?

TMS is an outpatient procedure, in which the patient stays awake the entire time and can be performed in a doctor’s office in less than 30 minutes. ECT is a procedure typically administered in a hospital with the patient sedated under anesthesia and can require an inpatient stay.

What does ECT do to dopamine?

Human studies indicate that ECT leads to dopamine system activation. Rudorfer et al. (69) reported an increased level of homovanillic acid (HVA), a measure of dopamine turn-over, in the cerebrospinal fluid (CRF) following ECT.

What medications are used in ECT?

The ideal induction agent for ECT is an agent with low anticonvulsant properties, rapid onset of action, short duration of action with a good safety and tolerability profile. The most commonly used agents for induction are propofol, thiopental, methohexital, etomidate, ketamine, alfentanil and remifentanil.

Where are ECT electrodes placed?

In bilateral ECT, one electrode is placed on the left side of the head, the other on the right side. In unilateral ECT, one electrode is placed at the top (vertex) of the head and the other typically on the right side.

Do antidepressants work better after ECT?

Combining antidepressant drugs with electroconvulsive therapy (ECT) does a better job of reducing symptoms of severe depression and causes less memory loss than using ECT alone, according to a new study.

Does ECT reset the brain?

ECT has been referred to as a “reset button for the brain,” which not only directly improves depressive symptoms, but also allows current medications to work more effectively.

Can ECT make anxiety worse?

The concern of some psychiatrists is that while ECT may help with depressive symptoms, it could worsen anxiety symptoms, including obsessional thoughts or panic attacks.

Why is ECT used as a last resort?

“The seizure is induced in a very controlled fashion, using a fairly precise delivery of an electric current.” Dr Davey says ECT is seen as a treatment option of last resort, to be used when nothing else has worked, or when there isn’t time to find the right medication for a patient, a process that can take months.

Who may benefit the most from electroconvulsive therapy?

Between 70 and 90 percent of patients experience a rapid improvement in symptoms. It may also help people who are acutely ill with mania, psychosis, catatonia, agitated dementia, post-traumatic stress disorder (PTSD), and suicidal thoughts.

How much is the cost of ECT?

ECT treatments cost $300 to $1,000 per treatment, with an initial course requiring five to 15 treatments followed by 10 to 20 maintenance treatments per year, the researchers noted. That means the annual cost can be more than $10,000, compared with a cost of several hundred dollars for many antidepressant medications.

Why is ECT so controversial?

Reasons for Controversy Three reasons are given for the aversion: 1) ECT is considered old-fashioned and politically incorrect; 2) it is forced on the patient; and 3) the memory disturbances are so severe and persistent that no rational human being would undergo this procedure, no matter how well-intended.
