Placement can be bilateral, where the electric current is passed from one side of the brain to the other, or unilateral, in which the current is solely passed across one hemisphere of the brain. High-dose unilateral ECT has some cognitive advantages compared to moderate-dose bilateral ECT while showing no difference in antidepressant efficacy.
Death can occur from any shock that carries enough sustained current through a vital organ or tissue. When an electric current flows through the brain or spinal cord, death due to asphyxiation may occur as a result of interference with the central nervous system's control of respiration, or through direct paralysis of the chest muscles.

The ECG and EEG are used to monitor electrical currents of the induced seizure. The nurse then ensures, “the patient is fully informed about their illness, why ECT has been recommended for them, the treatment process initially and throughout the course, allaying fears of the patient or their family may have about ECT and directing their ...
The electrical stimulation used in HWT differs from other forms of electrical stimulation such as TENS in terms of its waveform; it is intended to emulate the H waveform found in nerve signals, thus permitting the machine to use less power while attaining greater and deeper penetration of its low-frequency current.
The vertical axis represents the current intensity in milliamp (mA), while the horizontal axis illustrates the time-course. In transcranial magnetic stimulation (TMS), an electric coil is held above the region of interest on the scalp that uses rapidly changing magnetic fields to induce small electrical currents in the brain. There are two ...
Very small currents may be imperceptible or only produce a light tingling sensation. However, a shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling. A strong electric shock can often cause painful muscle spasms severe enough to dislocate joints or even to break bones.
About 280 million people worldwide and 26 million people in the United States have depression, which is a leading cause of disability. Some 30% to 40% of people with depression do not experience ...
ECT is the use of electrical currents to produce a seizure while under general anesthesia. It is thought to reset brain chemistry and may be beneficial in treating severe mental illnesses, including catatonia. [1] Exercising is shown to be beneficial to reduce symptoms of catatonic depression.
