Multifactorial pathogenesis: ought we to classify disease or treat the individual's causes of disease?

Added to the uniqueness of most of us imparted by HLA, our individual differences in the expression of other genetic traits, foetal period steroid imprints on brain and other functions, and regulators shared by body and mind indicate that each one of us (except most monozygotic twins) is born as a unique individual whole (I). Mechanisms suspected to be contributing ones in classified synovitides appear to correspond to individually exaggerated or depressed modes of response by physiological mechanisms linked to our unique individual wholes (II). If we upgrade the importance of influences of combinations of 'contributing' mechanisms, the importance of the alleged unknown fundamental causes of these diseases diminishes (III). This broad interpretation of 'multifactorial pathogenesis' can probably be applied to many common types of disease (IV), implying that disease classifications may poorly reflect the individual's causes of disease (V). There is reason to challenge modern concepts about disease (VI).
