Transcranial Magnetic Stimulation in Depression
The study examines efficacy of repetitive transcranial magnetic stimulation in treating severely depressed patients who are medicated.
Medicated, treatment resistant, depressed patients are randomized to active or sham repetitive transcranial magnetic stimulation (rTMS). Responding patients go into a six months follow-up period.

This study will examine the effects of high frequency, repetitive Transcranial Magnetic Stimulation on decision-making and smoking behavior.
Repetitive transcranial magnetic stimulation has been shown to be moderately effective in the treatment of major depression. Theta burst stimulation (TBS) is a new form of rTMS that may ex...
This is a pilot project to study if repetitive Transcranial Magnetic Stimulation (rTMS) will benefit patients with bipolar depression safely. Based on published studies, this study hypothe...

Medical and Biotech [MESH] Definitions
The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.
A technique that involves the use of electrical coils on the head to generate a brief magnetic field which reaches the CEREBRAL CORTEX. It is coupled with ELECTROMYOGRAPHY response detection to assess cortical excitability by the threshold required to induce MOTOR EVOKED POTENTIALS. This method is also used for BRAIN MAPPING, to study NEUROPHYSIOLOGY, and as a substitute for ELECTROCONVULSIVE THERAPY for treating DEPRESSION. Induction of SEIZURES limits its clinical usage.
A persistent activity-dependent decrease in synaptic efficacy between NEURONS. It typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. Long-term depression appears to play a role in MEMORY.
Decompression external to the body, most often the slow lessening of external pressure on the whole body (especially in caisson workers, deep sea divers, and persons who ascend to great heights) to prevent DECOMPRESSION SICKNESS. It includes also sudden accidental decompression, but not surgical (local) decompression or decompression applied through body openings.
Depression in POSTPARTUM WOMEN, usually within four weeks after giving birth (PARTURITION). The degree of depression ranges from mild transient depression to neurotic or psychotic depressive disorders. (From DSM-IV, p386)
