"Psychotherapy is a set of techniques believed to cure or to help solve behavioral and other psychological problems in humans. The common part of these techniques is direct personal contact between therapist and patient, mainly in the form of talking. Owing to the nature of these communications, there are significant issues of patient privacy and/or client confidentiality."
Electroconvulsive Therapy (ECT):
"Electroconvulsive therapy is a procedure in which electrical currents are passed through the brain to trigger a seizure. Although researchers don't fully understand just how ECT works, it's thought that the seizure causes changes in the brain chemistry. Given in a series over several weeks, ECT can help alleviate the symptoms of certain mental illnesses."
"It is handling your own troublesome situations by exercising deliberate conscious control to improve the outcome of the situation. It is recognizing your own personal weaknesses and working to overcome those faults and improve yourself. It sometimes involves changing others or the environment to improve your own circumstances or feelings, but self-help primarily focuses on changing your own behavior, feelings, skills, cognition (thoughts), or unconscious processes. Self-help is the conscious reasoning part of your "self" changing other aspects of your internal self, your actions, and your situation. It is self-improvement by yourself."
St John's Wort:
"The way in which St. John's wort works to help depression is unclear. It contains at least ten different chemicals that may help improve mood. St. John's wort [...] helps stop the breakdown of these monoamines and increases the level back to normal. This helps to improve mood in people who are feeling low or depressed."
"The investigational treatment involves placing a magnet on the head and stimulating key regions of the brain with electromagnetic fields. Unlike another depression treatment, electroconvulsive therapy (ECT), rTMS does not require anesthesia, so patients can eat and drink what they want before treatment and often can drive themselves to and from their appointments."
Sleep Deprivation Treatment:
"Sleep deprivation was shown to be effective in more than half the patients treated and in many types of depression. And if one course of sleep deprivation treatment didn't help relieve depressed patients' symptoms, often a second course did.
