 | | ECT was introduced as a treatment for schizophrenia in the 1930s, and soon became a common treatment for neurologically based disorders affecting mood. |
 | | ECT also decreases the functioning of norepinephrine and dopamine, inhibiting auto-receptors in the locus coeruleus and substantia nigra, respectively, causing more of each to be released. |
 | | Nearly all ECT devices deliver a lower current, brief-pulse electrical stimulation, rather than the original sine wave output; with a brief pulse electrical wave, a therapeutic seizure can be induced with as little as one-third of the electrical power used by the older method, reducing the risk of confusion and memory disturbance. |
