**Core Concept**
Electroconvulsive therapy (ECT) is a psychiatric treatment involving electrical stimulation of the brain to induce seizures, primarily used for treating severe, treatment-resistant depression and certain other psychiatric conditions.
**Why the Correct Answer is Right**
The mechanism of ECT is thought to involve the release of neurotransmitters such as serotonin and norepinephrine, which can help alleviate depressive symptoms. The therapeutic effect of ECT is believed to be related to the neuroplastic changes that occur in the brain as a result of the induced seizure. These changes can include increased activity in areas of the brain involved in mood regulation, such as the hippocampus and prefrontal cortex.

**Clinical Pearl / High-Yield Fact**
ECT is often considered a treatment of last resort for severe, treatment-resistant depression, and its effectiveness can be influenced by factors such as the presence of mood stabilizers or antipsychotic medications.
**Correct Answer:** C.
