Proposed and tested an algorithm for diagnosis of Moebius strip like pathology, as prerequisite for treatment correction. The algorithm is reduced to initialization of study objects as a Moebius strip, in particular symptoms, syndromes, diseases, multimorbid states; clarification of investigation objects as non-orientable two-dimensional surface; cutting a Moebius strip like clinical data, variability to form two disjoint Moebius strips; clarification of chirality Moebius strip turn; the determination of Moebius strip like constituents as the object of research and their 3D representation; clarification of Moebius strips turn chiralities of constituents; the adoption of diagnostic and therapeutic solutions based on geometry of the pathogenetic and sanogenetic mechanisms. Thus, our algorithm may be basis for making diagnosis and treatment decision.
