SUMMARY
Nonlinear Diagnosis Computer System uses the torsion method which at the moment is one of the most advanced methods of diagnostics of the cellular magnetic fields. Unlike MRI and computer tomography, the NLS-analysis does not need high intensity magnetic fields; it uses low intensity fields with a low frequency similar to brain theta waves; nowdays is used as a diagnostic tool for the human body. It is able to locate the allergens in the body and it also identifies the modifications in the body induced by the allergens observed through endocrine, biochemical and metabolic changes. The adaptative response due to allergenic load appears mainly in the neuroendocrine controlling system and the immune system as functional and metabolic shifts. This shifts are detected as entropy changes in specific locations of the nervous system related as an ultimate homeostatic adjusting appliance. After some delay, organic disturbances are expected to be seen in structural and metabolic patterns of the cells. The correlation between the presence of allergens and functional modifications such as digestive, respiratory and cardiovascular disorders is stated by studies of patient cases.
