Electroconvulsive therapy has a proven mechanism of action. When using it, the level of norepinephrine and other catecholamines in the hippocampus, frontal cortex, and basal ganglia increases. Dopamine secretion is increased in the striatum.
The indications for the appointment of electroconvulsive therapy (ECT) are:
- depression in the context of bipolar disorder and paroxysmal schizophrenia;
- resistant depressive states.
There are emergency and routine indications for ECT. Emergency indications include:
- depression with strong motor response and physical exhaustion;
