Neuropsychiatric disorders are generally accompanied by a change in brain activity (hyperactivity or deficiency compared to normal activity). Therefore, intervention in brain activity may provide treatment for different disorders. In this paper we review various methods of brain stimulation: some that are familiar and have been in use for several years such as electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS); and others that are new and still being studied but have obtained promising preliminary results such as vagus nerve stimulation (VNS), deep brain stimulation (DBS], magnetic seizure therapy, transcranial direct current stimulation (tDCS] and near-infrared therapy. For each method we describe the procedure, proposed mechanisms, side effects and current status in research and in the practical field.

Münchausen syndrome by proxy (also known as factitious disorder by proxy) is a psychiatric disorder which consists of fabricating or inducing illness in a child, usually by his mother. The motivation for the perpetrator's behavior is receivng satisfaction from the investigations and treatments that the child receives and from the medical environment, as part of a unique mental disturbance. External incentives for the behavior (such as economic gain) are absent. ⋯ Suspicious signs and symptoms include prolonged and illogical course of disease, odd complications, exacerbation that appear just before discharge from the hospital and symptoms that occur only in the presence of a specific care giver. Münchausen syndrome by proxy is not very rare. It appears in all ethnic groups, socioeconomic status and educational backgrounds.
