Local ELF-magnetic field: a possible novel therapeutic approach to psychology symptoms.

The recorded EEG of some brain regions of patients such as attention deficit hyperactivity disorder (ADHD), depression and etc. are different in comparison to healthy people. The disease improves with modifying the patient EEG that this is the basis of neurofeedback training. The main disadvantage of neurofeedback training demands patient's collaborative and active participation during treatment sessions, while some of patients such as addicts, depressed people and ADHD children cannot easily concentrate in direction of therapist's purpose. Furthermore, extremely low frequency magnetic fields (MFs) can affect brain signals and change them that in some cases lead to clinical effects. This report proposes if by locating small coils in desired region proceeds to local exposure of brain and happens in different frequencies or intensities and the effects of each MF in brain signals get analyzed then by knowing its effects we can make changes in patient voluntary without direct participation of patient in his/her brain signal changes. In the other words by changing type of the MF exposure and immediate record of brain signals we can fallow brain signals by observing the immediate record after exposure, with changes in the amplitude and the next exposure frequency, the therapist tries to direct the brain signal of desired region to the purpose. The possibility of approving this hypothesis in spite of contradictory effects about recovery or appearance of depression because of the MF and ability of local magnetic field exposures in changing of brain signals get reinforced to some extent.
